Chevrolet Corvair

A little history

When one thinks about American cars, stereotypes most probably come to his or her mind, as hefty sizes and weights, chromes, V8 engines, and so on. Still, American engineers sometimes proved to be capable of creating something original. In the case of the Corvair, they were poorly rewarded for their efforts.

The Corvair’s concept was due to Edward Nicholas “Ed” Cole, on Chevrolet’s payroll since 1933. During the Fifties, he was named chief engineer, then general manager of General Motors’ biggest seller. He already had an eye on the many rear-engine cars developed in Europe, particular the Volkwagen Beetle, so different from anything Detroit was producing, yet so popular in America. So Cole thought the time was ripe for an American-made rear-engine automobile.

The Corvair, as it was to be called, would be a compact car. Nash and its successor AMC had opened the way with the Rambler, imitated by Studebaker and its Lark. Simultaneously, imports peaked by the end of the decade. The three major corporations had to react and each prepared a compact car of their own. This riposte took the shape of three compacts that all appeared for model year 1960. Ford unveiled the Falcon, a very conventional car and, as it turned out, the most popular of the bunch. Plymouth introduced the Valiant, which unfortunately suffered from a tormented style announcing the odd-looking Chrysler cars of the next few years – until the group’s chief designer Virgil Exner finally got the boot. Concurrently, Chevrolet presented its Corvair, fitted with a rear-mounted, air-cooled flat six. Completely new to GM’s engineers, this original architecture had proved difficult to develop – even after entering production, the Corvair’s engine would leak oil in enormous proportions. Its main problem though would come from its rear suspension. The swing axle should have been complemented by an anti-roll bar. GM’s accountants didn’t follow the engineers’ suggestion: with all its unusual technologies, the Corvair was expensive to build, and some costs had to be cut to make the car competitive on the market. This choice would prove decisive in the catastrophe that loomed ahead.

Still, things were not going so bad yet. Sales were inferior to those of archrival Ford, but good enough. Performance was rather limited, though the 2.3-litre six was working hard to provide at least good acceleration, but the body had been masterfully crafted – ironically, the Corvair’s look would inspire many designers: the NSU Prinz 4, the Simca 1000, the Hino Contessa, or the Fiat 1300/1500 all mimicked the unsuccessful Chevrolet. In addition to this, the range was limited at first, including only only two- and four-door sedans. Developing Chevrolet’s offer could help, so during the next few years many models being added to the catalogue: the short-lived Lakewood station wagon, the Greenbrier minibus and Corvan 95 van and pickup, and a convertible. But it was the Monza Spyder that determined the future of the car. Launched in 1962, it added to the car a turbocharger (a rare equipment in those days), boosting the power to 150 hp and transforming the Corvair, with its peculiar handling, into an affordable sportscar. The whole range benefited from the new image carved by the Monza Spyder, finding a niche that allowed it to remain on Chevrolet’s pricelist despite the introduction of a more conventional compact, the Chevy II.

Sold as a sporty compact, could the Corvair finally be a success? Two elements played against it, once again. The first was the introduction of the Ford Mustang halfway through model year 1964. Compact, nimble, cheap, sporty, somewhat different, the new Ford was all this… as the Corvair had been before it. That is to say, the Mustang could do anything the rear-engine Chevrolet did, only better. In particular, the Corvair had to settle with its turbocharged six as its most potent engine, while the Mustang offered V8s and a whole range of optional heavy-duty parts that could turn it into a genuine performance machine. Inevitably, the Corvair was rapidly expelled from its very last stronghold.

The second event that negatively affected the Corvair’s career was the book from a then-unknown lawyer, Ralph Nader. In Unsafe at any speed, Nader violently denounced the absence of concern the manufacturers demonstrated for safety. All automobile companies were under fire – even Rolls-Royce was cited – but no car received harsher critics from Nader than the Corvair, which handling was supposedly extremely hazardous. In addition, Nader argued that in case of a frontal shock, the driver would be impaled by the steering column. Many claims later proved to be, at least, grossly exaggerated, but the fatal blow had already been given nonetheless.

Nader’s attacks paradoxically came as the Corvair was bettering itself. For 1965, a second generation of the car was unveiled. The swing axle gave way to a much superior independent suspension on all four wheels. One year later, Chevrolet would face Ralph Nader’s critics by fitting a two-piece steering column, then a collapsible one after another year. Best of all perhaps, the new Corvair, inspired in part by the Corvette Stingray, was lower and longer, and definitely very elegant.

Alas, this second Corvair was leading a fight that was already lost. In 1966, Chevrolet decided to stop the development of the car to concentrate on its challenger to the Mustang’s supremacy, the oncoming Camaro. Shortly thereafter, advertisement expenses were drastically reduced. Year after year, demand unsurprisingly dropped. Production figures were six-digits numbers when the car had been initially launched; in 1969, for its very last year, only six thousand left the factory. A sad end for a car that has been extremely ambitious at its outset.

Chaparral 2

A little history

Jim Hall was already acknowledged as a talented pilot when he proved an equally skilled engineer. The year was 1963, and the young Texan was just finishing his first complete season in Formula One. Having recorded some promising results at the wheel of a private Lotus, he was courted by several teams for 1964… but never returned – he already had other plans.

Actually, during the very same season, Hall had raced the first real machine he had designed on the American sportscar’s stage, the Chaparral 2. A very innovative car, this Chaparral, named after a Texan bird specie, was a spyder built around an inventive semi-monocoque structure carrying a fibreglass body drawn with aerodynamics in mind. Power was provided, as it was customary with most American racers of the time, by a small block V8, namely a Chevrolet. Fed by four two-barrel Weber carbs, it was good for about 420 bhp. This huge amount of power passed through a Colotti 4-speed gearbox before reaching the rear wheels.

Soon Jim Hall’s approach proved successful. Constantly improved thanks to Chevrolet and Firestone’s supports, and even more to Hall’s methodical ways which pushed him to experience ever new ideas on his cars, the Chaparral 2 soon was the car to beat. The original 2 was followed by the closely-related 2B and 2C, the latter riding on an aluminium chassis. Chaparral also replaced the gearbox his car originally used by a self-developed automatic transmission, a rather uncommon characteristic that would become its trademark for years to come. After three seasons, the Chaparrals had won 22 of the 39 races they had entered, which gave Hall even more ambition.

A logical step for a highly successful entrant in a national competition is to advance to the international level, that is, in Hall’s case, the World Championship for Makes. At the same time, a brand new championship for V8-powered spyders was being organized in North America, the CanAm. Which one would Hall next set his goal on? The Texan didn’t even choose – he decided to enter both in 1966.

In endurance racing, Chaparral’s car would be the 2D, a small coupe capitalizing on Hall’s experiences in the field of aerodynamics. After showing unfulfilled promises during the two first races of the championship, a large air intake was added to the 2D’s roof and the car was sent to Europe. Facing large and potent opponents of the likes of Ferrari and Ford, the Chaparral won the 1000 km held on the twisty Nürburgring circuit. Unfortunately, the 2D was rather unreliable and this extraordinary success remained an exception.

In CanAm, the 2E spyder pioneered the use of a high-mounted wing which added downforce directly to the rear axle. Actually Hall wasn’t the first one to imagine the benefits such an aileron could generate – as early as 1956, Michael May (another pilot-engineer, this time from Switzerland) had provoked much laughter by fitting such a peculiar contraption to his Porsche 550 spyder for a race at the Nürburgring. No one laughed anymore when May threatened even the fastest competitors during practice. As a result the other teams asked the organizers to ban May, which they did… at the same time postponing a crucial development for motor racing by a dozen years.

The experience of both the 2D and the 2E were incorporated into the design of the 2F, Chaparral’s endurance racer for 1967. Another coupe, the 2F was equipped with a huge movable wing – having his left foot available thanks to the use of an automatic transmission, the pilot would depress a pedal in long straights in order to set the wing flat and generate minimum drag then, approaching a curve, he would release it – the wing would then flip into an angle, increasing both drag, which assisted braking, and downforce, which helped cornering. Unfortunately, the 7.0-litre, 525 bhp Chaparral 2F was as fragile as its predecessor the 2D, and would have demonstrated nothing if not for an unexpected victory at the BOAC 500 at Brands Hatch, the very last race of the season.

Chaparral two-pronged effort saw the team entering a 2G spyder in CanAm, but the McLaren racers were rapidly gaining momentum and were increasingly impossible to beat. The FIA having banned prototypes of more than 3.0-litre displacement for the 1968 endurance season, Chaparral could concentrate on the CanAm, but the 2G, then the 2H (the “Great White Whale”) which replaced it in 1969, proved disappointing.

In 1970, Chaparral took the CanAm world by storm with the 2J, which seemed finally able to shake McLaren’s utter supremacy. The 2J was powered by 7.4-litre Chevrolet V8 delivering about 680 bhp, but the reason of its success wasn’t there. A second engine, a tiny Rockwell twin placed at the rear of the car drove two large fans which literally sucked the car onto the road – in theory, so much suction force was generated that, turned upside down, the car could have stuck to the ceiling of a room… Practice times recorded by the 2J were astounding and, though the car was rarely able to finish a race, there was much moaning in the paddock against Chaparral. Near the end of the season, McLaren and other CanAm entrants were able to convince the organizers that the side skirts used by the 2J were illegal, and the car was banned. Seeing its progressive approach forbidden, Chaparral retired from racing.

About the models

Model: Chaparral 2D - Chevrolet
Year: 1966
Event: 1966 Nürburgring 1000 km, driven by Phil Hill and Joakim Bonnier (finished 1st overall)
Maker: Del Prado, or whoever builds models for Del Prado
Scale: 1/43
Distributed by: Del Prado through an unknown Japanese press series

Same car, a few weeks later in the Sarthe. I didn’t have on hand the necessary tools to unscrew the car from its stand when I took this photo, so I’m afraid you’ll have to wait for more pictures! Likewise, I’ll wait until I have a better look at the model to give it a rating.

Lotus Elise

A little history

After a long period of uncertainty, Lotus found in Romano Artioli a new owner who understood what the company’s philosophy was all about: building lightweight GTs offering impressive performances, not overpriced supercars. Though the old Esprit would remain in production, a new model, small and affordable, would be added to the range: the Elise.

The Elise’s development was a protracted one, ending in the car being launched only in September 1996, just as Artioli had to relinquish the small British company to Malaysian giant Proton after the collapse of his over-ambitious project. The small roadster was constructed on an aluminium chassis fitted with Lotus’ traditional fibreglass body – as a result, at a time when extra electrical and electronic equipments had driven the weights of all other cars to towering heights, the Elise didn’t even reach 750 kilograms. With a 1.8-litre four borrowed from Rover, and rated at no more than 120 hp, the Elise was capable of impressive performances. Though its top speed was obviously no match for bigger GTs, its capacities in terms of acceleration and cornering enabled the car to challenge most of its larger and more expensive competitors.

Still, some customers were asking for more performance, that Lotus was keen to deliver. A 145 hp version debuted in 1999 as the Elise 111S, followed during the next year by the 179 hp Exige. The very same engine was also fitted to a lightweight roadster, the minimalist 340R, which with less than 570 kilos could be considered a modern interpretation of the original Lotus Seven.

During the same period Lotus decided to measure itself against the likes of Porsche or Mercedes-Benz in the FIA GT championship. Cunning interpretation of the FIA rules gave birth to the Elise GT1, which used the road car’s chassis but shared few other elements with its namesake. Its career wouldn’t essentially extend on more than a single season, as the car was only marginally short of being catastrophic. Its chassis lacked potential, aerodynamics weren’t its strong point, its gearbox was often failing and none of its engines (the GT1 could be fitted either with the 3.5-litre from the Esprit, brilliant but fragile, or the 6.0-litre lent by the Chevrolet Corvette, a GT block that proved insufficiently powerful) was satisfactory. Following the pitiful demonstration of the GT1, Proton, appalled by the staggering cost of the program, signified to Lotus that its unfortunate foray into international motorsports was over.

A Series 2 Elise was unveiled for model year 2001, which introduced many minor improvements and a body redesigned in a similar yet much more aggressive style – I personally prefer the more rounded, somehow more feminine look of the Series 1, but this is purely a matter of taste. The Elise is still produced today, the main event of its later years being the switch to a 1.8-litre Toyota engine following Rover’s collapse.

A simple model that nonetheless does the trick perfectly well. At just above two euros it left my budget virtually unscathed in order to purchase rarer models proposed by more expensive brands. My rating is 12/20.

A correct die-cast but I have serious reservations about the clear covers on the headlights, which get loose with extraordinary ease – if you present your model out of its box, take care not to lose any, of otherwise unscrew the chassis, then add two little drops of glue on the inside of the body, where their lone stems are supposed to hold these faulty parts. My rating is 11/20.

Chevrolet Captiva

A little history

Taking design cues from the S3X concept car presented by parent company Chevrolet, built on an extended version of the Saturn Vue’s platform, the Daewoo Windstorm appeared in 2006 as a 2007 model. General Motors’ strategy since its takeover of the South Korean company having been to limit the use of this brand to its native country, even if this SUV is widely exported it bears the name Chevrolet Captiva in most of the world, with the exception of Australasia where the car is rebadged as a Holden Captiva. A pretty large vehicle graced by a rather pleasant styling, the Windstorm/Captiva is powered by a 2.0-litre turbocharged diesel, a 2.4-litre four or a 3.2-litre V6.

(This car’s history will be expanded in due time, please be patient.)

About the model

Facing the choice of buying either the model of a vintage automobile or that of a brand new car, I’ll always go for the older one. Nevertheless no rule goes without exception and on the date I bought this Captiva there could have hardly been a newer model. My decision probably has something to do with the quality and care for details that Norev displayed to reproduce this SUV. There isn’t much complaints I could make so I’ll give this die-cast a 15/20.

Chevrolet Nova

A little history

The Nova was an upscale variant of Chevrolet’s first traditional compact car, the Chevy II, introduced after General Motors realized that the unconventional Corvair displeased a large fringe of its potential customers. Launched in 1962, the Chevy II was well-timed as the Corvair’s sales plummeted as a result of a not-fully-justified campaign against it by security-minded (and somewhat publicity-seeking) lawyer Ralph Nader, and absorbed most of the sales of its unfortunate companion, a happy development for General Motors which could have otherwise seen its customers flock to its competitors’ showrooms.

A second-generation Chevy II appeared for 1966, but retained a squarish look close to the one which graced its predecessor. In late 1968, a third-generation car was introduced for the 1969 model-year, which dropped the original “Chevy II” name in favour of the sole “Nova”. The range was also simplified, from then on concentrating on two-door coupes and four-door sedans.

One of the most desirable third-generation Novas were the Super Sport, or SS. Though this performance package had been introduced as early as 1963, the combination of a fresh, clean design and more-potent-than-ever engines made the SS an instant classic. I’ll refrain from calling the Nova SS a “muscle car” – those who know me can say why: I abhor using the “muscle car” name outside the strict intermediate class and, as the Nova is per se a compact, it doesn’t qualify as such. Whatever you call it, it is nothing more than a name anyway, and that the Nova SS was a great performance machine is what really matters. Lighter and nimbler than a genuine muscle car, the Nova SS, fitted in standard guise with a 350 (5.7-litre) V8 good for 300 bhp could really do good when its throttle was tickled.

Chevrolet knew the potential of its third-generation Nova, and built them for six straight model years until the end of 1974 – quite a long life for an American car of this era. Then a new Nova, the depressingly plain fourth-generation, was introduced. Production of the Nova was halted for good a few days short of Christmas 1978.

About the model

Model: Chevrolet Nova SS396
Year: 1970
Maker: Ertl
Scale: 1/43
Distributed by: Ertl, "American Muscle" series ref. 0889GD, sold as part of the set "Class of 1970" ref. 32003
Acquired: brand new, in June 2005, in Manila, Philippines

Ertl is certainly better known for its numerous 1:18 scale models rather than its 1:43s. That’s a shame, as models of American classics which are both well done and affordable are scarce in the smaller scale. This Nova SS comes as part of a three-car package which also includes a Ford Torino Cobra and an Oldsmobile 4-4-2. With a nice metallic green paint, good-looking wheels and specific badges fitted all around, the car definitely looks great. The only drawback is the windshield wipers, moulded with the windshield rather than added as separate parts. Still, not bad for a rather low price. My rating: 14/20.
