Opel operates 10 vehicle, powertrain, and component plants and four development and test centres in six countries, and employs around 30,000 people in Europe. The brand sells vehicles in more than 60 markets worldwide. Other plants are in Eisenach and Kaiserslautern, Germany; Szentgotthárd, Hungary; Zaragoza, Spain; Gliwice, and Tychy, Poland; Aspern, Austria; Ellesmere Port, and Luton, Great Britain.[37] The Dudenhofen Test Center is located near the company's headquarters and is responsible for all technical testing and vehicle validations.
We took the ferry from Newhaven to Dieppe and then headed down to Forges-les-Eaux, along winding D-roads through quiet villages and dense forests, scenes to be repeated over the following three days. What you notice immediately about the Calibra is how civilised it is. That V6 engine is a gem, not especially powerful by today’s standards but honestly quick and genuinely refined.
Automatic Emergency Braking with Pedestrian Detection works automatically at speeds between 5 and 140km/h. For speeds between 5 and 30km/h a 0.9g deceleration is applied to reduce the impact speed of the collision. For speeds of 30 to 140km/h the system reduces the speed by up to 50km/h. To reduce speed by over 50km/h the driver needs to provide additional braking. The operational speed range depends on the type of obstacle detected:
Opel campaigned the car extensively in motorsport too. The rally version was uncompetitive, but Opel eagerly waded into the 160mph traffic jam that was the International Touring Car Championship. The ITCC was created from the German DTM series, in which Opel had struggled. A rule change allowed Opel to use a new 480bhp V6 derived from the road car. The resultant four-wheel-drive monster carried Manuel Reuter to the 1996 ITCC driver's crown and Opel won the manufacturers' gong, beating Alfa Romeo and Mercedes-Benz. It was the Calibra's finest hour.
The transfer gearbox in the AWD models — the same as used in the Vauxhall Cavalier AWD—was somewhat on the flimsy side, liable to suffer damage from conditions such as minor differences in tyre wear or tyre pressure between front and rear axles. Since front and rear tyres would naturally wear at different rates in normal driving, it was necessary to swap front with rear tyres every 15,000 miles (24,000 km).
That makes it a similar size and weight to the outgoing Corsa, at a whiff over four metres long and 1177kg. Beyond that, new means new. Every panel on the mildly Adam-ised, slightly more butch exterior is different. Every component forward of the A-pillars is new. Every suspension component, too, as are the pick-up points for the front MacPherson struts and the rear torsion beam.
The GSi's engine mapping had been carried out by Opel tuning specialists Irmscher. A model with the 82 PS (60 kW) 1.4 L multi point fuel injected engine, which was otherwise mechanically identical to the GSi, also became available as the Nova SRi in the United Kingdom. In January 1988, a turbocharged version of the Isuzu diesel engine was introduced, with power increased to 67 PS (49 kW).[8]
