"The engine was the 2.2 Turbo III, the third turbocharger setup CC had developed. Mopar engineers worked with Lotus to create the engine, which included Lotus-designed heads; it was the first four-valve-per-cylinder engine Chrysler had ever built, and featured balance shafts, a double overhead cam, and an intercooled Garret turbocharger. With the R/T's only transmission - the A-568 five-speed manual, created for that engine - it could reach 60 miles per hour in between 5.8 and 6.8 seconds."

And by the way, my first car, which was the one before the contour, was a 1992 Plymouth Voyager, unfortunately not using the 2.2 mentioned above, but rather a paltry 2.5 liter inline 4 rated at 100 hp and 135 ft/lbs of torque. It had its uses though as a party van though.
