There was even a performance version named 500 E from 1990 to 1993 and E500 from 1994 to 1995, which was developed in close cooperation with Porsche. In fact, Porsche actually hand built the cars at its Rossle-Bau plant in Zuffenhausen, Germany.
The E500 was powered by a specially tuned 5.0-liter V8 engine rated at 322hp (326PS) at 5,700 rpm and 480Nm (354 lb-ft) at 3,900 rpm, allowing for a zero to 100km/h (62mph) sprint time of 5.5 seconds and a top speed of 260km/h (162mph).[...]
