1986 Vauxhall Carlton GSi 3000

The 1986 Vauxhall Carlton/Opel Omega was an impressive leap into the 1980s. The slippery new car boasted an Audi-beating drag co-efficient of 0.28, and a well sorted RWD chassis that challenged BMW’s overall ability. But it was a little dull – until the good men an GM shoehorned in the Senator’s 3-litre straight-six. With 177bhp on tap, the be-spoilered GSi was capable of topping 135mph, and doing it all day long. The best was to come in 1990, though, when the 24V version was installed, producing Luton’s first genuine BMW 535i-beater in the process.
