Intelligent lightweight design begins on the computer, using the newest virtual development methods. The specific use of various steel grades and connection methods enabled the Corsa’s big weight reduction. This includes the consistent use of high-strength and ultra-high-strength steels, as well as the optimization of load paths, connections, structure and form. Compared with the previous model, the body-in-white is 40kg lighter. The next Corsa is based on the multi-energy platform for small and compact cars, which allows a variety of propulsion systems. Customers can choose from combustion engines or the all-electric version.
There were two distinct generations of the Kadett B: 1966-1967, and the 1968-1973. Bob Lutz had a hand in the key feature that distinguished the two. The torque-tube/leaf-spring rear suspension was replaced for 1968 by a coil-spring and control-arm set-up, designed to both improve ride and handling, especially in reducing the Kadett’s tendency to tippiness. Bob had recently arrived at Opel, where he mentioned that the Kadett had a bit of a rep in the US for being a bit tippy, especially in a J-turn maneuver. The engineers told him that the new rear suspension (seen here in this picture) would eliminate that, and invited him to see for himself. The result is self-evident (full story here).
All of this was a product of corporate leverage and synergies and all of these corporate-sounding words that sound so much better when Jack Donaghy says them. The cynical say that the idea to badge Opels as Saabs happened a few years later with the second-generation 900, which shares a lot of pieces with the Calibra, but in reality they're very different cars. As a Saab, I say the Calibra would've been derided from the start and its reputation ruined that way. Listen to Chris Goffey and his beard go on about its styling and merits when he drove it as the Vauxhall Calibra on old Top Gear.
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).
