To celebrate its 100th anniversary, Cadillac debuted the Cien concept car for 2002. Constructed in carbon fiber composite, this mid-engine two-seater featured scissor-style doors, a removable hardtop, and a speed-sensitive rear spoiler. A 750-horsepower, 7.5-liter Northstar XV-12 concept engine provided power. GM Executive Director of Advance Design Studio in England, Simon Cox, was responsible for the Cien's design. He made an appearance at the Chicago Show during the First Look for Charity black-tie event.
