Even though this performance sedan had humble origins, it was the fastest car in the world at the time and epitomized the concept of a sleeper or Q-car. Name it.

The Vauxhall Carlton — also known in continental Europe as the Opel Omega — spent most of its existence in the shadow of its fancier sibling, the Senator. However, that all changed when Opel/Vauxhall teamed up with Lotus to built an ultra-high-performance variant, the Lotus Carlton. Powered by a twin-turbocharged 3.6-litre V6, it had a staggering (for a family sedan) 382 horsepower. This meant 0 to 60 in 5 seconds and a top speed of 190 mph — which was faster than the Ferrari Testarossa or the Lamborghini Countach.
