The first generation Omega was a mid-sized luxury car offered in Europe by Opel, the German subsidiary of GM, between 1986 and 1993. Sold in Britain under the Vauxhall marque and rebadged as the Carlton, my friend’s dad had a mid spec model when I was growing up. I always thought of it as a poor-man’s BMW 5-series. And I don’t mean that in a bad way: it was actually a pretty admirable car, offering luxury features to the masses like ABS, an on-board computer and a dazzling (at the time) LCD instrument display. I suspect most people by now have forgotten all about them. But there is one very special edition of the Omega/Carlton that enthusiasts of my age could never forget, the one breathed on by Lotus. The British sports car manufacturer took the hottest version of the car, the 3000 GSi, enlarged the 3.0 liter 24v motor to 3.6 liters, added two Garratt T25 turbo chargers, a six speed manual gearbox taken from a Corvette and an aggressive bodykit. The result was a menacing and breathtakingly quick uber sedan, with 377 hp on tap and a top speed of 177 MPH.
