Chevrolet Firenza }} }} The HC Viva (1970–79) was mechanically the same as the HB but had more modern styling and greater interior space due to redesigned seating and positioning of bulkheads. It offered two- and four-door saloons and a fastback estate with the choice of either standard 1159 cc, 90 tuned 1159 cc or 1600 cc overhead cam power. No 2.0 GT version was offered with the new range, although the 2.0 became the sole engine offering for Canada, where the HC became the
Firenza, marketed by Pontiac/Buick dealers without the Vauxhall name. The cloned
Envoy Epic was dropped as Chevrolet dealers now carried the domestic
Chevrolet Vega. The HC was pulled from the Canadian market after two model years amidst consumer anger over corrosion and reliability issues. The American influence was still obvious on the design, with narrow horizontal rear lamp clusters, flat dashboard with a "letterbox" style speedometer, and a pronounced mid bonnet hump that was echoed in the front bumper. A coupé version called the
Firenza was introduced in early 1971 to compete with the
Ford Capri and forthcoming
Morris Marina Coupé. It was available in deluxe and SL forms, with the latter sporting four headlights and finally resurrecting the missing 2.0 twin-carburettor engine from the HB Viva GT. The basic 1159 cc engine was enlarged to 1256 cc in late 1971 and with this the 90 version was removed from the line-up. The overhead cam engines were upgraded in early 1972, the 1.6 becoming a 1.8 (1759 cc) and the 2.0 (1975 cc) twin carburettor became a 2.3 (2279 cc). At this time, the Viva 2300 SL and Firenza Sport SL did away with the letter-box speedometer and substituted a seven-dial instrument pack. Firenza SLs had a two round-dial pack, though all other Vivas and Firenzas stuck with the original presentation. In September 1973, the Viva range was divided, the entry 1256 cc models staying as Vivas, with the 1.8-litre engine an option on the Viva SL with an automatic transmission. The 1.8- and 2.3-litre models took on more luxurious trim and were rebadged as the
Magnum. The whole range of Viva-based cars received safety equipment upgrades at the same time, with power-assisted dual-circuit brakes (with discs in front) being made standard. Safety belts, reclining front seats, two-speed windscreen wipers, and undercoating were also made standard across the board. In 1977–78, there was also a limited-edition ES model with a slightly improved specification over the E model. For 1977, the SL was replaced by the GLS, essentially marrying the plusher Magnum trim and equipment with the base 1,256 cc pushrod ohv engine. These models all had the full seven dial instrument panel, velour seating and Rostyle wheels, among many other upgrades. Viva production was scaled down after the launch of the
Chevette in spring 1975. Originally a three-door hatchback (also sold as the
Opel Kadett City), the Chevette later offered two- and four-door saloons and as of 1976 a three-door estate which all but usurped the Viva's position as Vauxhall's small car entry. Nonetheless, the Viva remained on sale until the latter part of 1979. The Viva was effectively replaced by the new
Vauxhall Astra, a variant of the front-wheel-drive Opel Kadett. By that time it was dated in comparison with more modern rivals like the
Volkswagen Golf. Production ceased at a time when European manufacturers were making the transition from rear-wheel-drive saloons to front-wheel-drive hatchbacks in the family car market. The end of production of the HC Viva in 1979 marked a significant moment for Vauxhall, as it would ultimately prove to be the last car to be completely designed by the company with no input from Opel. The company's next car — the 1972 Victor FE range — was based on the
Opel Rekord D; albeit substantially modified by Vauxhall and ended up having little interchangeable content with the Opel car. However, subsequent models (such as the
Chevette — an
Opel Kadett C with a restyled front end and the HC Viva's powertrain) would set the eventual precedent — that all future Vauxhall cars would be badge-engineered and German designed
Opels, or in the case of the 2004 Vauxhall
Monaro, a rebadged Holden. The domestic market launch of the Viva HC coincided with one of the UK's periodic surges of
debt fueled economic growth, and the latest Viva became Vauxhall's fastest selling new model of all time, chalking up its first 100,000 units in just months. 640,863 Viva HCs were produced, making combined Viva production top the 1.5 million mark. The millionth Viva, a gold HC, was driven off the production line by politician
John Eden amid much celebration on 20 July 1971. Although most Vivas were produced at Vauxhall's
Ellesmere Port plant in northern England, the company's production lines were by the standards of the time flexible, and the millionth car was a product of the
Luton factory. This local derivative offered the small British four or a locally built
Chevrolet 2.5-litre engine. After a 1975 facelift and some changes to the lineup, these lost the "Firenza" badges and were sold simply as the Chevrolet 1300 and 1900, as the smaller 1960 cc version had replaced the earlier 2.5. The car was facelifted, with a new front design which mimicked that of the bigger
Chevrolet 2500/3800/4100, with the grille protruding somewhat and being set apart from the headlights. The Firenza range originally consisted only of four-door saloons, but South Africa also saw a three-door hatch developed off this rather than taking on the then new Chevette/Kadett City; this was first shown in June 1976 and the first car rolled off the production line in August. This mixture used the T-car's rear hatch and taillights, but was a Viva ahead of the B-pillars. The arch around the rear hatch opening was considerably stronger than the T-car's, to suit local road conditions. Also, the was larger than one would expect from a car this size, to suit local road conditions and petrol sales restrictions. The split rear-seat folded down. With the new
Chevrolet Chevair recently introduced, cost prohibitions made such a creation a better proposition than bringing in an all-new car. Local parts content was high from the get-go, with some Hatch models reaching 71.15% right away. The 1300 has Vauxhall's 1256 cc engine, carried through from the Firenza, while the 1900 has a locally built 1960 cc Chevrolet cast-iron inline-four; a smaller version of the 2.5 seen earlier in the Firenza. At the time of introduction, the Weber carburetted manual 1900 claimed SAE and a top speed of for the Hatch. Automatics received a Rochester carburettor and more torque-oriented tuning; max power for this version is . The 1300 and 1900 were both available in De Luxe or LS trim, with a four-speed manual transmission and an available three-speed automatic for the 1900s. The Firenza was plagued with significant quality problems which were made worse with the lack of availability of spare parts due to the frequent
labour strikes in the UK at the time. Some of the Firenza's common problems included brake failure and engine fires. In 1972, angry Firenza owners organized into the "Dissatisfied Firenza Owners Association" and engaged in public demonstrations to publicize the car's quality problems and demand compensation from General Motors for repair costs and depreciation; the Firenza had become so toxic on the used car market that one year old examples with low mileage were worth less than a quarter of their MSRP and dealerships refused to take them as trade-ins. Multiple Firenzas caught on fire during a protest outside of the
Canadian House of Commons. The protests, combined with reports of a 19-year-old woman perishing in an accident caused by her Firenza's steering failing prompted intervention by the Canadian government, while GM denied the problems and attempted to protect the Firenza's reputation through
deceptive marketing before withdrawing it from the Canadian market in early 1973. The Disaffected Firenza Owners Association attempted to sue General Motors, but their lawsuit was unable to proceed as Canada didn't have any laws establishing
class-action lawsuits at the time, prompting Prime Minister
Pierre Trudeau to oversee their creation. The failure of the Firenza hurt Vauxhall, which considered Canada an important export market but was forced to withdraw from as a result. In a 2018 retrospective,
Autofocus.ca described the Firenza as "the worst car Canada ever saw" and claimed that its obscurity outside of Canada is the only thing preventing it from being considered one of the
all-time worst cars alongside the likes of the
Chevrolet Vega and
Ford Pinto, while also describing it as Canada's equivalent of
Ralph Nader and the
Chevrolet Corvair.
Grumett Several cars based on the Vauxhall Viva were produced from 1970 until 1976 by Grumett in
Uruguay. They came in different models, including a double-cab, two-door pick-up, with different Vauxhall and Opel engines. The body was
fibreglass; some original Vauxhalls were imported to serve as moulds. Mechanicals were either Vauxhall or Opel, depending on the batch. ==Name revival==
