On August 24, 2009, Motortrend and Automobile Magazine conducted a one-of-a-kind race up Loveland Pass, pitting four high-cost, high performance vehicles – a Mercedes Benz E550, a Maserati Quattroporte, a BMW 550i, and a Jaguar XF Premium 5L V8 – against…a 6-cynlinder Lincoln MKS. The race itself is not a straight line story, but a climb up one of the highest passes in America, with the winner determined by the treacherous, winding road with thousand-foot drop-offs and torturous hairpin turns.

Watch each burst of acceleration and wheel-clenching turn to see which vehicle emerges as challenging course’s the top performer.
