The Opel Calibra is a coupé, engineered and produced by the German automaker Opel between 1989 and 1997. In the United Kingdom, where it remained on sale until 1999, it was marketed under the Vauxhall brand as the Vauxhall Calibra. It was also marketed as the Chevrolet Calibra in South America by Chevrolet, and the Holden Calibra in Australia and New Zealand by Holden.
The Calibra was introduced to counter the Japanese sports coupés, of the end of the 1980s and beginning of the 1990s. It employs the running gear of the first generation Opel Vectra, which had been launched in October 1988. Calibra production was based in the Opel factory in Rüsselsheim, Germany, and the Valmet Automotive factory in Uusikaupunki, Finland, where production was consolidated in November 1995.
The Calibra was initially only available with front-wheel drive, but from November 1990, four wheel drive became available.
The Opel Calibra was styled by GM's designer Wayne Cherry, and German designer Erhard Schnell. As a front-wheel drive three door hatchback coupé based on the Vectra A chassis, its ride and handling are not significantly better than that of the large family car from which it grew.
Though it had a stiffer chassis as a whole (better torsional rigidity in NM/Deg).The 4WD turbo version of the car, which had independent rear suspension, featured the rear axle of the Omega A with some minor alterations to it.
When launched on 10 June 1989, the Calibra was the most aerodynamic production car in the world, with a drag coefficient (Cd) of 0.26. It remained the most aerodynamic mass production car for the next ten years, until the Honda Insight, along with the Audi A2, were launched both in 1999, with a Cd of 0.25.
All later 16V, V6, 4x4 and turbo models had a worse Cd of 0.29, due to changes in cooling system, underbody, use of spoked wheels and glass detail.
During its lifetime, the Calibra was much more popular in Europe, and outsold its nearest rival, the Ford Probe, which was considered to be underpowered, and very American for most European drivers. However, in the United Kingdom, it failed to outsell the Rover 200 Coupé, which offered comparable performance, but without 4WD in the top of the range models.
In July 1990, after General Motors bought a stake in Saab, it was reported the Calibra would be badged as a Saab in the United States, but these plans did not materialise. There were also plans for a cabriolet version to be produced, but these too failed to materialise, although Valmet Automotive built two fully working, red coloured prototypes in 1992, with the 2.0 litre, 8 valve engine.
A third body was also produced for use in flexibility tests. In the summer of 1994, the Calibra received a light facelift. Most noticeably, the manufacturer badge migrated from its place atop the leading edge of the bonnet into the front grille. Throughout the production run, several special models were launched.
In the United Kingdom, this began with the 'Tickford' conversion in October 1991, however, only twenty six Calibra's were ever converted. This was followed by Vauxhall's own Special Edition range the SE1 in 1993, and ran through to the SE9 in 1997. These limited run editions had often unique aspects. For example, solar yellow paint on the SE2, or "Icelandic" blue on the SE6. Neither colours were found on any other Calibra.
There was also a DTM edition available only in white, in celebration of the Calibra's success in the German Touring Car Championship at the time. In other parts of Europe, special models included the "Keke Rosberg" edition, the "Cliff" edition, the "Colour" edition and "Last" edition. Some special models included a numbered plaque on the ashtray.
In September 1995, the Vectra A was replaced, but Calibra production continued until June 1997. Although a smaller coupé (the Tigra) was available, the marque was left without a mid sized coupé until the Astra Coupé was launched in 2000, and with the introduction of the Opel Speedster in 2000, three years after the Calibra was discontinued, Opel finally offered a sports car again.
Power was initially from 2.0 litre 8 valve (85 kW/115 bhp C20NE) and a Cosworth designed 16 valve fuel injected (110 kW/150 bhp C20XE) four cylinder redtop petrol engines.
For 1992, a turbocharged 2.0 litre 16 valve engine (150 kW/204 bhp C20LET, the turbocharged version of the C20XE) was added to the range. With four wheel drive, a six speed Getrag manual transmission (F28/6) and a claimed top speed of 245 km/h (152 mph), this flagship model finally gave the Calibra the dynamics to match its looks.
The Turbo model was also notable for the five stud wheel hubs and the extreme negative camber (inward lean) of its rear wheels, which is apparent even from a cursory visual inspection. However, it was not a strong seller.
In 1993, a 125 kW/168 hp 2.5 litre V6 (C25XE or SE4) was introduced. Available with both manual and automatic transmissions, the V6 was not as fast as the Turbo, but was rather more civilised, and proved to be more reliable than the complex four wheel drive model. 1995 saw the introduction of the X20XEV Ecotec engine, a new version of the classic C20XE 16 valve or "red top" engine.
This marked a reduction in power from 150 bhp (112 kW) to 136 bhp (101 kW) for the 16 valve version, although the Turbo continued with the C20LET.
The last Calibra Turbos were produced in the beginning of 1997, before a final run of Calibra Turbo Limited Editions were rolled out. These were all finished in jet black paintwork with Irmscher spoiler, BBS RX 16" alloys and colour coded body fittings. This final incarnation was also lowered by 35mm on Irmscher springs and dampers.
