The Opel Ascona is a mid-sized car produced by Opel. It was produced in three separate generations from 1970 to 1988, beginning with rear-wheel drive and ending up as a front-wheel drive J-car derivative. In motorsport, the Ascona 400 rally car driven by Walter Röhrl won the World Rally Championship drivers' title in the 1982 season.
The Ascona took its name from the lakeside resort of that name in Ticino, Switzerland, and already in the 1950s a special edition of the Opel Rekord P1 was sold as an Opel Ascona in Switzerland, where the name was again used in 1968 for a locally adapted version of the Opel Kadett B into which the manufacturers had persuaded a 1.7-litre engine borrowed from the larger Rekord model of the time.
The Opel Ascona A launched in 1970 and sold across Europe was, however, the first mainstream Opel model to carry the name. The Ascona was introduced in September 1970 and ended production in August 1988, to be replaced by the Opel Vectra A.
Ascona A
In the fall of 1970, Opel presented its completely new vehicle range in Rüsselsheim (internal project code 1.450). The Opel Manta coupé was launched on September 9, followed by the Opel Ascona on October 28 in two and four-door sedan forms, plus a three-door station wagon, called the Caravan or Voyage. These models were positioned between the existing Opel Kadett and the Opel Rekord.Ascona B
The second generation Opel Ascona B was presented in the 1975 Frankfurt Motor Show. It was available as a two or four-door sedan. There were related two and three-door coupé models in the Opel Manta range. There was no estate body.The Ascona B retained the same engine range as its predecessor, although the 1.9 L was increased to 2.0 L in 1978, and versions with higher compression ratio and needing 98 octane petrol, dubbed S, were available alongside the 90 octane models. The 2.0 E model had a Bosch L-Jetronic electronic fuel injection, and a 2.1 L diesel motor was added to the Ascona B range in 1978.
Ascona 400 rally car
Built in 1981, the 1980 world champion Walter Röhrl took the rally car to victory and won the World Rally Championship drivers' title in the 1982 season. The car was developed by Opel alongside the Manta B 400 model which consisted of the same changes. Irmscher and Cosworth were hired as partners for the project, Cosworth to deliver a 16 valve double cam crossflow head for the engine, and Irmscher for the exterior and interior styling. Cosworth delivered the heads to Opel and Opel soon discovered a major mistake. The plan was to use the 2.0 litre engine block but this did not produce enough power. Time was running out and Opel badly needed to do something. Opel took the 2.0E block and gave it an overbore, installed larger pistons, other pistonrods, and installed the crankshaft of their 2.3 litre diesel CIH style engine. Results was a 2.4 litre engine. The 2.4 litre engine gave way to some massive power outputs using the 16 valve head. The street versions of the 400 therefore came with 144 PS (106 kW) engines, using the Bosch fuel injection of the Manta GSi and GT/E series. However in race trim they were delivered putting out 230 PS (169 kW), which could be improved further to 340 PS (250 kW), while still using normally aspirated engine components.Ascona C
The Ascona C was launched in August 1981 as part of General Motors' J-car project. This was Opel's second front-wheel drive car since the introduction of the Kadett D in 1979. This car was manufactured in Rüsselsheim, Germany, Antwerp, Belgium and Luton, England, and was sold in the UK under the name Vauxhall Cavalier and Chevrolet Monza in Latin America. The Cavalier Coupé was phased out, but the Opel Manta was retained in the UK (the last car to be badged as an Opel in the UK before the brand was phased out there in 1988). There were no longer sheet metal differences between Opel and Vauxhall models after 1982. The Ascona C won the "Golden Lenkrad" at the end of 1981 and was West Germany's biggest selling car. wikipedia.orgmore on: http://toplegendarycars.blogspot.com/2012/04/opel-ascona.html
