Last Boulder Coffee & Classics of the Season: A 1931 Bugatti Charms Children of All Ages

Your lazy correspondent arrived a half hour late on the last Sunday morning in October as he was less ready to start at 8 than was his trusty English car.  An even later arrival, however, made him forget all about getting in the long line for coffee at Spruce Confections.  It's a 1931 Bugatti Type 40A, and in the photo above, its owner invites a car-bewitched youngster to have a look inside. From a perch on the driver's seat, that lucky kid will see this: the manual controls of a hand-built, Machine Age work of art with no microchips, or even plastic, anywhere...

The Type 40A replaced the Type 40 in May 1931 after 5 years and 790 examples of Ettore Bugatti's "entry level" car.  Only 40 of the Type 40A were released by the Bugatti workshops in Molsheim, Alsace Lorraine.  Nobody used the phrase "entry level" back then, however, and not many would've thought to base a touring car around a racing engine.  In the Type 40, this was the Type 37 GP 1.5 liter aluminum overhead cam four cylinder with 3 valves per cylinder (2 intake, 1 exhaust); the Type 40A got a longer stroke for 1.6 liters, and received twin spark plugs per cylinder. 

The T40A engine, like all classic Bugattis, resembles a piece of Cubist sculpture, enhanced by the swirls of the "engine-turned" finish on the aluminum firewall.  Though Bugatti was an early adopter of advances like multi-valve aluminum engines, overhead cams, and supercharging, the company stayed with rigid suspensions front and rear, and mechanical, cable-operated brakes.
Parked next to the Bugatti we found this Allard* J2X. Offered by Sydney Allard's British firm from 1952-54, the J2X was aimed at American amateur racers during the postwar boom in road races promoted by the SCCA...
For this reason, the J2X was often equipped with Cadillac's 331 cubic inch V8, but some, like this example, featured Chrysler's then-new V8, which had the same displacement, but with hemispherical combustion chambers. The J2X engine was moved back 7 inches in the chassis to improve handling over the previous J2 model built in '50 and '51. Those were powered by Caddy V8s, flathead Ford V8s, and a few Lincoln V12s.  Only 83 of the J2X were built, following 90 J2s. Handling, even on the improved J2X, could be dramatic, as both cars featured a swing axle front suspension...
In the same lineup as the Bugatti and the Allard we found a Ferrari F40, a Jaguar XK120 rom the same era as the Allard, and a silver 1968 Dino 246 that is a frequent visitor to the Sunday sessions. By this time people were cheerfully ignoring the No Parking Any Time signs...

Other Bugatti neighbors included the black Ferrari 328GTS in the foreground and a wild, racing red cousin based on Ferrari's V8 engine design... 
That would be the F40, introduced to celebrate Ferrari's 40th anniversary as a car maker in 1987. The mid-mounted, 2.9 liter, 4-cam, twin-turbocharged V8 sends over 470 hp to the rear wheels through a 5-speed transaxle.  400 units were planned, but over 1,300 were eventually built by the time production stopped in 1992. Styling was by Pininfarina, as on Ferrari's previous supercar, the 288 GTO.
The yellow Alfa Romeo Type 916 Spider below may have been less familiar to visitors than the F40, because along with its 916 GTV 2+2 sister car, it was never exported to the USA.  It was popular in Europe though; the front-driver won design and car of the year awards after introduction in 1995. Over 80,700 of the 916 (Spider and GTV included) were built before production ended for the coupe in 2005 and the Spider in 2006.  Styling, by Pininfarina, combined wedge themes with rounded contours...
This Spider, a 1998 model built for export to Canada, has Alfa's 2 liter, 16-valve Twin Spark inline 4.  Other engines offered over the production run included 12- and 24-valve versions of Alfa's 60 degree 3 liter V6, and also the 3.2 liter version. Transmission choices were limited to 5- and 6-speed manuals.  

As the morning warmed up, the owner of the 1959 Ford Skyliner retractable hardtop gave a demonstration of the hinged steel top's operation.  The Skyliner retractable appeared after much anticipation in 1957 and sold over 20,000 copies that year, nearly as many as 2-passenger T-Bird which was in its last year. 1959 was the final year for the retractable, with a bit over 12,900 examples finding homes. A similar rear-hinged deck design, with lots of motors and relays, would appear on the soft-top Lincoln Continental 4-door convertible for 1961...
This little 1972 Steyr-Puch* Haflinger was one of over 16,000 made by the Austrian Steyr-Puch combine from 1959 to 1975. The tiny (59" wheelbase!) 4-wheel driver was intended for the Austrian military, and used the same 643 cc (39,2 cu. in.), rear-mounted air-cooled boxer twin that appeared in Steyr-Puch's comparatively hot-rod version of the Fiat 500 body, and also in a rare, alloy-bodied 2-seater GT coupe.  The Haflinger was  also adopted by the Swiss Army, sort of like that famous knife.  Horsepower was less than in the Steyr-Puch Imp 700 GT* engine, though, at around 30 max.  And according to the owner, the military did not enjoy the tendency of the carb to vapor-lock.

Weather protection seems about the same as you'd get with a mobile jungle gym. We especially enjoyed the strap detail that substitutes for the doors, which according to the owner, are fabric over a steel frame.  He's fitted a rear vision camera because with the top installed, rearward vision vanishes.  Rear seats fold forward, but there are no seatbelts because of the hinge design...   

The Lotus 7 offered similarly casual weather protection, with not much in the way of doors, but with a sturdier-looking roll bar.  Early Sevens (1958-60) used Ford side-valve fours, but the Super Seven (1961-73) adopted Ford's overhead valve Kent four in 1.3, 1.5 liter sizes, with the Lotus twin-cam available in Series 3 .  Power output ranged up to 125 or so, which doesn't sound like much, but in a 1,600 lb. car gives a power-to-weight ratio better than the V8-powered Allard J2X, with better handling too.  After 1973 Caterham Cars built the original S3 design (not the wider, heavier S4) under license from Lotus, and maintained the Lotus tradition of offering the car in kit form...
The Jensen Interceptor appeared in 1966 with one of the last styling jobs by Italy's Touring Superleggera.  The first 3 test cars were bodied by Vignale; Jensen built the rest of the steel bodies in fastback coupe and (after '73) convertible form, with a few late notchbacks, over 6,400 cars in a decade.  Wheelbase was just over 105", power came from a Chrysler 383 V8 (with over 230 cars optioned with the 440 starting in '71), disc brakes were standard, and the only element that suggested cost savings was the live rear axle. The rarer FF model (320 built) as offered from '66 through '71, and offered Ferguson Formula all-wheel drive along with Dunlop Maxaret anti-lock brakes, a first in a production car.  One Hemi-powered prototype was built. How can you tell an Interceptor from an FF?  Well, there are two diagonal vents behind each front wheel on the FF and a longer wheelbase (109"), and all FFs are right-hand drive.
There were some working class cars to go with all the upper crust stuff on Sunday morning, including this tasty oval-window VW.  The small backlight disappeared for 1958...
The lineup of old cars covered both sides of 8th Street and stretched around the corner on this crisp autumn morning, and our extremely casual popularity count tallied the most numerous makes as follows: Porsche in first place by a pile, then Triumph, with Austin Healey and Alfa Romeo tied for 3rd. We wish everyone involved an enjoyable and not-too-expensive winter of tuning and tinkering...

Twilight of the Independents: America's "Small Five" Car Makers in the 50s



In 1954, if you'd wandered into a Kaiser showroom, you might have encountered a fiberglass-bodied 2-seater like the one above. It's a Kaiser Darrin*, a product of the 1953 merger that made Kaiser-Frazer into Kaiser-Willys. A 161 cubic inch Willys* F-head six mounted in Kaiser's compact Henry J chassis provided 95 horsepower, not enough to catch the Corvette from that year, or the Nash-Healey*, or the Jaguar XK120 that sold for a bit less than the Darrin's $3,700 and led this price class.  Styling by namesake designer "Dutch" Darrin, with odd sliding doors, was the main attraction here.  In '54, you could also walk into your Nash showroom and order a Pinin Farina-bodied coupe like the one below; it followed a PF-styled roadster that appeared in '52 to replace the British-styled effort from '51.
Why were America's independent car makers displaying so much interest in 2-seaters?  Well, they'd noticed there was a sports car boomlet going on, ignited by returning GIs who'd seen small roadsters in England, and by postwar prosperity, which allowed more people to purchase a 2nd car for weekend fun, which sometimes extended to amateur road races organized by the Sports Car Club of America.  Crosley had tried an answer to the MG TC with its Hotshot in '49 and Super Sports a year later.  They offered about half the power and the same sketchy weather protection as the MG, but weighed and cost lots less, and so Crosley sold a couple thousand before stopping car production in '52. In the meantime, Jaguar had caught Detroit's attention by offering the XK-120, which took over the market for high performance cars by offering the most speed and style for the dollar.  Enough were sold to prompt Nash to release the Healey in '51, and GM to release Chevy's Corvette in '53.  Both cars originally appeared with the same 102 inch wheelbase as the XK120.  Nash had released its compact Rambler in 1950, and hired designer Pinin Farina to give its 1952 big car line some European flair...
He applied his talents to the Nash-Healey in the same year. The new sports cars generated showroom traffic but not great sales; Nash sold 162 Nash-Healeys in 1953, and mighty GM sold only 300 Corvettes. But the smaller independents needed some way of attracting attention to any offerings with higher profit potential in this period, when a price war between Chevy and Ford was taking sales from entry-level cars from the independents.  The success of the low-priced but nicely-equipped Nash Rambler, about the same size as the expensive Nash-Healey, also suggested their might be an untapped market for smaller cars.
These included Hudson's Jet, introduced for 1953 as an effort to compete with that Rambler, which had sold 160,000 copies in the previous 3 years.  Hudson was best known for the "step-down" fastback sedans and the coupes that were then dominating NASCAR with their low center of gravity and torquey flathead six.  But that design (one is parked next to the blue Jet below) had originally appeared for 1948 and carried into 1954, the year Hudson was absorbed by Nash.  Hudson offered a stripped base model, but prices were not competitive with the Rambler, which offered more standard equipment, or with the "standard size" Chevy and Ford.  Jet sales were not helped by clunky, tall bodywork; Hudson chief A.E. Barit had insisted on headroom for tall men in hats, which gave the 105-inch wheelbase Jet awkward proportions. 
Hudson stylist Frank Spring, father of the "step-down" design, had a different demographic in mind than men in hats when he designed the Hudson Italia* in 1953. The name referred to bodywork built in Italy by Carrozzeria Touring, using their Superleggera system of aluminum panels carried on steel tubing.  The "production" version shared the Jet's 105 inch wheelbase and 114 hp, 202 cubic inch flathead six, which offered only adequate performance considering the car's $4,800 price.  So the Italia didn't appeal to the same crowd as the Jaguar or the Nash-Healey, which could boast of racing success.

Styling included a wraparound windshield, doors wrapping into the roof (at 54 inches tall, the Italia was 7 inches lower than the Jet), a concave deck lid, odd rocket-tube tail lights, and inside, contoured bucket seats facing standard Jet instruments and an inappropriate column shift.  "Production" is in quotation marks because only 25 Italias were offered to the public after Nash took over struggling Hudson in 1954; there was also a lone prototype on a shorter 100 inch wheelbase (which might have helped body flex issues) and one 4-door prototype called X-161.
The 2-seaters from Kaiser, Nash and Hudson were never intended as mass-production showroom draws, but Studebaker's 1953 Starliner* and Starlight coupes were.  The low, sleek, Italian-influenced coupes offered seating for 5 on a 120.5 inch wheelbase, and unlike those others, a modern V8.  Design for the landmark coupes was by Bob Bourke at Raymond Loewy's studios; Loewy stands with the car below.
Unfortunately, Studebaker management tooled up for more of the taller 2 and 4-door sedans than the sexy coupes, and could likely have sold at least twice as many of these as they did.  Still, 106,259 sporty coupes (pillarless Starliner and B-pillar Starlight, Commander V8 and Champion 6 included) is impressive for the two years it was offered.  Any of the other independents likely would've been thrilled by those numbers...


Packard, long associated with solidly built, conservatively engineered and styled cars, tried for a more youthful look on their Caribbean convertible, launched the same year at the Loewy Studebakers. Like Hudson, Packard had stayed with inline, side valve engines in the postwar era, and would only have their V8 ready for 1955. In the meantime, there was this jazzy convertible, a restyle of the new-for-1951 body shell by Richard Teague. No Caribbean hardtops would be offered until 1956, final year of the big Packards. Though they were  among the priciest Packards ($5,400-$6,100), the '53 and '54 Caribbeans were on the 122" Clipper wheelbase, and the '53 version got 180 hp from its 327 cubic inch straight 8 with 7 main bearings.  For '54, the last year for the inline 8, there were 9 main bearings, displacement rose to 359, and horsepower to 212.  Choosing a wheelbase 5" shorter than the big Patrician's was a wise design move, along with the restrained (for the Fifties) use of chrome, which nicely outlined the wheel arches, emphasizing the wire wheels.  The full rear wheel arch was unique to the Caribbean, as was the hood scoop.  
Along with the medium-priced Clipper, Packard offered the Patrician at the top of the line, including the $6,500 Derham-modified Formal Sedan below, one of the old coach builder's last special Packard styles, which featured a retractable divider window between the front and back cabins. Only 25 were built that year; Derham modified similar numbers each year from 1951-54.  Packard also offered a few limousines bodied by Henney.
Packard did better with the Caribbean, selling 750 of the '53 model, and 400 of the '54 shown below.  The '54 version was less effective visually than the '53, losing the full rear wheel arch, and gaining two-toning and chrome that ignored the fender forms.  Packard merged with Studebaker in October 1954; Packard would release its last major design effort, the big Packard with the long-awaited V8 and electric self-leveling suspension, in January 1955.  The merger was an unsuccessful move, as outside of an expanded dealer network, there weren't many cases where the either of the 2 companies could exchange elements the other needed.  And they both had something neither needed: lots of red ink.  It might have made more sense for Packard to merge with Nash, as the latter did not have a production-ready V8, and in fact Nash offered one of Packard's new V8s (the 327) in its 1955 Nashes and Hudsons.  And it would likely have benefitted both Studebaker and Willys to merge, but we'll get to that... 
Another independent that became more unprofitable as the Fifties wore on was Kaiser-Frazer, a company formed after World War II to challenge the Big Three.  Instead of a promised front-drive car, what Henry Kaiser and Joseph Frazer delivered in 1947 was a slab-sided, rear-drive sedan with an already outmoded side-valve six from Continental Motors, which sold the same engine to Checker for their cabs.  Kaiser had gained fame and credibility creating a production line for ships during the war, and Frazer had held top posts at Chrysler, Willys-Overland and Graham-Paige; this led some people to expect great things from the company.  In 1950, there was a spurt in interest (and in sales) when Kaiser-Frazer released the new 1951 Kaiser with body designed by Howard Darrin, who'd done some classic Packards in the 30s and 40s.  The new car was lower than most of the competition, with a low belt line and glassy greenhouse, and was offered in more styles than previous Kaisers. There were now two-door coupes (shown below) as well as two and four-door sedans. For a couple of years, Kaiser also offered a Traveler version, a sedan with a pioneering hatchback feature, because there was no station wagon.  There were no convertible or pillarless hardtop versions either; perhaps some of the money spent on tooling up the close-coupled (and rare) coupe below would have been better spent on those.
Instead, in order to secure a government loan, Kaiser entered the low-priced field with the Henry J. also for 1951. The separate-chassis fastback matched the 100" wheelbase of the unit-body Rambler, and though over 80,000 sales made for an encouraging first year, sales decreased greatly each year until the finale in 1954, when only 800 were sold, and when the chassis was used for the Kaiser Darrin 2-seater.  The Henry J was only offered as a fastback 2-door, with the Willys 161 cubic inch 6 in the DeLuxe, and the Jeep inline 4 (134 cubes) in the Standard.  This highlights a recurring Kaiser problem, the lack of its own engine...
                   
So you're probably wondering if the rumored Kaiser V8 finally arrived with the tasteful restyle of the Darrin body on the '52 Manhattan below, with its curved one-piece windshield above a padded dash, and restyled tail lights and bumpers nicely complimenting the curves. There is, for example, the "V" that's affixed to the deck lid.  But it doesn't stand for anything, because Kaiser couldn't afford to get their V8 engine design into production. Because of high production costs, Kaisers (and Frazers, discontinued after 1951), especially this top line Manhattan model, were forced to compete with makes like Oldsmobile and Dodge (and in '53, Buick), which offered modern V8s with more power than the old flathead 6 in the Kaiser. This wasn't "the world's most advanced new car", just a deft restyling effort.                                  
Kaiser management responded belatedly in 1953, spending $70 million to purchase Willys, which as we will see, gave it a more modern compact car to sell, as well as access to government contracts for Willys Jeeps and trucks.  It also readied a restyle of their big sedans for 1954, with a front end inspired by a Buick show car, a big, wraparound rear window, and a 140 hp supercharger option for the old inline 6.  The restyle made for a dandy future collector's item, but sales continued a downward spiral: 4,110 cars in 1954, and 1,291 in the final year, 1955.  

The Willys finally gave Kaiser dealers a modern competitor for the Rambler. The tidy, compact Willys Aero* below first appeared in 1952 and offered a unitized body on a 108" wheelbase (matched later by Chevy's Corvair, Studebaker's 109" Lark and even the Rambler), and a clever redesign of the Willys 161 cubic inch 6 with an F-head (inlet over exhaust) similar to designs then produced by Rover and Rolls-Royce. The Aero was relatively light and fuel- efficient, and before the small-block Chevy V8 appeared, offered one of the best power-to-weight ratios of a low-priced car.

Unlike Kaiser, Willys offered a pillarless hardtop by 1953.  The Bermuda shown below is from 1954, and shows the bigger tail lights and one-piece rear window added after the Kaiser takeover, which also prompted offering the 226 cubic inch flathead six from the Kaiser (not an improvement).  Studebaker might have chosen Willys for a merger, had they taken a good look.  They'd have gotten access to the Willys government contracts, both companies would have benefitted from a bigger dealer network (especially Willys), and Willys could have used Studebaker's V8 in its pickups and wagons (or in a hotter Aero), while Studebaker would have had a modern compact car to sell, 6 years before the Lark.  One of the Willys Aero models had already been named the Aero Lark.  So no problems with copyrights either...
While the Kaiser car line disappeared in the US after 1955 along with the Willys Aero line, Jeep sales provided profits for Kaiser-Willys, Kaiser Motors, and after 1963, Kaiser-Jeep.  The only other surviving independent of the Not So Big Five, American Motors, bought Jeep from Kaiser in 1970.  Jeep sales, including sales of the pioneering SUV, the Wagoneer introduced by Kaiser Jeep in 1963, generated income for AMC when their conventional cars struggled, and when Chrysler bought AMC in 1987, it was solely to get rights to the Jeep line, which survived under Daimler Chrysler ownership (1998-2007) and continued after Fiat purchased a stake in Chrysler (2009).  The Jeep line has continued to generate US sales for Stellantis since Fiat Chrysler and the French PSA group merged in 2021. The Willys name currently appears on special versions of the Jeep Wrangler and Gladiator pickup. It's the only surviving nameplate that was originally offered by an independent from our twilight era, and evidence that maybe Henry J. Kaiser wasn't so crazy to buy Willys when his own car company was losing money.

Forgotten Classic: Healey, Before and After Austin

Mentioning "Healey" to Americans of a certain age (or level of car obsession) usually summons up recollections of the Austin-Healey, either the Big Healey that was a fairly common sight on our roads from the mid-Fifties through the late Sixties, or the tiny Sprite Bugeye that appeared in the late Fifties.  But there were other Healeys before and after those cars, and they may not ring as many bells in the dusty attic of memory. After World War 2 Donald Healey founded a specialist car building firm in Warwick.  He had been shot down while flying for the Royal Flying Corps in the First World War, and raced cars after it, winning the 1931 Monte Carlo Rally in an Invicta.  By the mid-Thirties (and his own late 30s) he was technical director of Triumph Cars.  The 1947 Elliott coupe above was atypically elegant (its body was by Beutler in Switzerland), but its chassis was typical of early Healey designs: a ladder frame with independent front suspension with coil springs and trailing arms, a live axle rear, and hydraulic drum brakes during a time when mechanical brakes equipped (or afflicted) many British cars. The engine was a 2,440 cc Riley that made 104 hp when equipped with twin SU carbs.  This was a twin-cam inline four, but with high cams and pushrods, not unlike the Lea Francis engine of the same period.  Most of the 101 Elliott coupes looked like the green car below, rather than the white one above.  Sincere and even friendly looking, but not what you'd call sleek...
Just over 100 of the Elliott coupes were built between 1946 and 1950; there was also a Westland open tourer that managed to sell 70 copies.  
In '49 and '50, Healey also offered the Sportsmobile (below); only 23 were sold.  This may have been the result of the clunky styling; the Sportsmobile looks like it was designed as transport for Wallace and Gromit.  Another drawback was a short-lived steering system with a triangular aluminum pivot plate; even minor wear in the pivot bearing resulted in sloppy steering.  Mobile, maybe, but not very sporting... 
Healey's Silverstone was a more sporting proposition. The name was a clue; it was named after a race track.  Appearing in July 1949, the Silverstone was designed to avoid a recently doubled purchase tax on cars priced over a thousand pounds; it sold for 975 GBP.  Bodied in cycle-fendered style (think Allard or Frazer Nash) by Abbey Panels, it featured the twin-carb, "underhead cam" Riley four, but was the first Healey with bodywork supported on a tubular steel frame, rather than the wood framing of previous models.  Despite success in racing, only 51 D Types, and 54 of the wider, more comfy E, were made before production ended in Sept. 1950.  The E Type had a wider cabin, bigger windshield and hood scoop, but traded bucket seats for a bench.  The green car below is a D Type.
The black car below is a coupe bodied by Tickford (who also bodied Alvis and Aston Martin chassis); the last one appeared in '54.  The red drophead coupe below it was bodied by Abbott in the same period.  Both shared the Riley engine featured in the Silverstone.  Many Healeys, like the Elliott, Westland and Abbott, were named after the coach builders who bodied them...

Around the dawn of the Fifties, as a result of Donald Healey meeting Nash president George Mason on an ocean liner, a plan was hatched to outfit Healey chassis with Nash six-cylinder engines.  Bodywork was nearly identical to the Panelcraft-bodied, Alvis-powered Healey 3 liter, which managed to sell only 25 copies.  But the new Nash-Healey, fronted by a Nash grille and released in summer of 1950, sold 104 copies Stateside, and a Nash-powered Healey finished 3rd at Le Mans in 1952, behind two Mercedes 300SLs but ahead of the Ferraris...
Those were good sales numbers for Healey, but probably seemed small to Mason at Nash. The American company had already hired Pinin Farina as a design consultant, so the alloy Panelcraft body was replaced by the more stylish Farina-styled steel roadster body shown below for 1952.  Size of the OHV six with special aluminum head stayed at 3.8 liters for '52, but increased to 4.1 liters for '53, when Nash added a coupe to the range.  Nash-Healeys kept the Healey front suspension design, but substituted a Nash Ambassador torque tube and rear axle.
The side-curtained roadster on the 102" wheelbase was joined by a coupe (108" WB) in 1953, and only a lightly reslyled coupe with reverse-slant C-pillar (below) was offered in 1954. The revised cars sold 402 copies over 3 years, not bad considering that the roadster, priced at $4,700, was over a third more than a Jaguar, while the $5,900 coupe was in Aston Martin territory...
1952 was a big year for Healey.  Not only was Nash-Healey production ramping up, but in answer to a need for a less expensive roadster that could be produced at Healey's factory, designer Gerry Coker sketched out the Healey Hundred, with its curvy contours tightly fitted over a 90" wheelbase Healey chassis powered by a 2.6 liter Austin OHV four.  As luck would have it, Austin and Morris had merged early in 1952 to form the British Motor Corporation, and when the minions of BMC saw the new car at that year's Earls Court show, they quickly made a deal with Donald Healey to mass-produce the car as the Austin-Healey 100.  That's Leonard Lord from BMC on the left next to Donald Healey...
Production began in 1953. The new Healey had plenty to recommend it to sports car fans in the USA: swoopy lines, sturdy mechanicals, and a friendly price around $2,900.  The 2.6 liter inline four's 90+ hp made it competitive in increasingly popular road races, especially after the 3-speed gearbox in the BN1 version was replaced by the 4-speed in the BN2. Our example Austin-Healey 100, in blue below, is parked next to a red Jensen-Healey from the early 70s; more on that later...
Note how designer Coker had finally found the fan-shaped Healey grille a happy home, and how the curve of the door sills mirrors the fender curves above.  Also note the curved uprights of the folding windshield and how they work with the curves.  The windshield glass was flat, and the curved sides probably made the side curtains an odd fit, but most observers thought it was a great-looking car.  This blue example has been owned by the same Colorado family for decades...
In 1955 Healey introduced the 100S, a factory racer made in only 50 examples and only that year; there were another 5 factory test cars. It looked like an Austin-Healey 100 with an oval grille, but it was more.  Alloy body panels replaced steel, four Dunlop disc brakes replaced drums, and a special aluminum cylinder head and twin carbs offered 132 hp. A 1955 Road & Track test gives a 7.8 second time for the 0 to 60 run, and a top speed of 120 mph, fast for the era. The photo below shows how the windscreen looks in folded-down position.  Healey selected their purchasers from a list of successful amateur racers; most of the 100S models seem to have been delivered with the white and blue paint scheme shown...
You'd be forgiven for thinking the green car below is a 100S model.  Actually it's a Healey rebuilt by Cape Motors in England, with a new alloy body like the 100S, a new chassis, an engine with the rare aluminum cylinder head, and 4 disc brakes.  
There were other attempts to increase power on the Austin-Healey 100, and some of these involved American V8s, and some of those involved power bulges on the hood.  Not sure what's going on with the cow-catcher bumper on the orange car, but the owner had a good sense of humor...
BMC had its own plans for more power, though, and in 1956, after 3 years of the four-cylinder 100, introduced the Austin-Healey 100-6. Still at 2.6 liters (actually 2639 cc to the Hundred's 2,660), it offered the smoothness of 6 cylinders with 102 hp; after a new cylinder head design from late 1957 the power increased to 117. The wheelbase increased to 92 inches; more power provided the excuse to offer alleged 2+2 seating in the BN4 offered from '56 on, while the BN6 offered in '58-'59 kept the two-seater's lines, all behind a new hood with scoop and a somewhat fussier oval grille than on the 100S.  The example below is from 1959...

In 1958, the year the BN6 appeared, BMC released the Austin-Healey Sprite, with 948 cc inline OHV four accessed by a hood in unit with front fenders including the famous Bugeye headlights, steel body designed again by Gerry Coker on an 80-inch wheelbase chassis, and everything pared down to a 1,460 pound weight and $1,795 price.  As with the AH 100-4 and 100-6, they sold thousands.  Ads highlighted the Sprite-powered speed record car, as well as the kinship to the Big Healey...
When the Sprite was released in the USA, designer Coker had gone on to work at Ford in Detroit, and was disappointed to see that his planned retractable headlights had been ditched by BMC for cost reasons.  But the Bugeye's trademark feature gave it an identity and a name, and some owners cannot resist pointing out that the car is, well, cute...
Bodies for the Sprite were built by BMC, while those for what soon became known as the Big Healeys were built by Jensen Motors...
Late in 1959 the Austin-Healey 3000 appeared, with 2.9 liter inline OHV six, still based on Austin's Westminster. At first, in Mark I and Mark II versions, these were offered as two-seater or 2+2 roadsters, all with side curtains and sketchy tops (above). In summer 1962 the Mark II convertible appeared with curved windshield and roll-down side windows. The 3000 substituted disc brakes at the front wheels; while drums remained at the rear.  Grille shape went to the simpler vertical bar design on the Mark II, and power went from 124 to 148 over the life of the 3000, which ended after the 1967 model year. The Convertible model below replaced the roadsters, and acquired a wood dash in the Mark III version which appeared in spring of 1964, around the same time as Ford's Mustang.  All Convertibles feature 2+2 seating.
New US safety regulations spelled trouble for the future of the Big Healey, and the father and son team of Donald and Geoff scrambled to save the car, and their manufacturing contract, by widening the 3000 model by half a foot and plunking a 4-liter Rolls-Royce inline six (inlet over exhaust valve) as supplied for the slow-selling Austin Princess into the 4000 prototype, of which a couple were built around 1966-7.  But this adaptation of a 15-year old design was doomed by the 1968 merger of Austin, Rover, Triumph and Jaguar into British Leyland, an unwieldly mess of competing design teams with a surplus of competing engines, including the 3.5 liter Rover V8 and Jaguar's 4.2 liter six.
Meanwhile, in 1962, the 23 year-old Italian designer Pio Manzu won the design competition sponsored by Swiss publication Automobile Year by designing a new body for the Big Healey, which was built by Pininfarina to Manzu's specifications.  As a sign that it might have pointed to a more modern future for the Austin-Healey, features of the Manzu design*, with its tall greenhouse, curved side glass and angular roof, appeared 3 years later on the MGB-GT, which was actually designed by Pininfarina.  PF improved on the concept a bit by substituting a large hatch for the conventional trunk lid on the Manzu design.
When the Healey concern found a new manufacturing deal to replace the BMC contract, it was with American importer Kjell Qvale and Jensen Motors, and the car they hatched was the Jensen-Healey. Appearing in 1972, it was a conventional two-seat roadster with live rear axle and disc brakes at the front only, like the Big Healey it sought to replace.  Chassis design was more rigid than that car, but testers found it was not rigid enough to avoid the cowl shake of the Big Healey. The one modern, cutting-edge feature was the twin-cam 2 liter inline four sourced, oddly enough, from Lotus.  The engine looked great on paper, making 140 hp from 2 liters with 4 valves per cylinder.  The new engine had not yet appeared in any Lotus product, so in a way the Lotus engineering team was using the Jensen-Healey team to do trouble-shooting on their new engine. And there was plenty of trouble on the Mk. 1 cars' engines, including water pump failures, oil leaks, gasket failures, low oil pressure, and fuel line leaks.  By the time the J-H team sorted out the Mk. 2 cars, their project was losing money.  Perhaps a better route to success would have been to use a proven production engine, like the Ford V6 in the Reliant GTE.  The Jensen-Healeys we see today have been mostly sorted out and offer plenty of fun; this red example has a Toyota 5-speed transmission...
By the time Jensen offered a 2+2 sports wagon version in 1975, Healey had withdrawn from the project, so the new model was offered as the Jensen GT.  With more development and some advertising, it might have filled the gap left by the Volvo 1800 ES. But the effort collapsed in 1977 for lack of funding, and Jensen was so invested in the Jensen-Healey that it collapsed too.
