Porsche 911 (996)

The Porsche 996 is the fifth generation of the 911 sports car, manufactured by Porsche from 1997 until 2006. The 996 replaced the 993 and was itself replaced by the 997 in 2004, although the high-performance Turbo S, GT2 and GT3 variants stayed in production until 2006. It had little in common with its predecessor: the first all-new chassis platform since the original 911 and a new water-cooled engine in place of the air-cooled one, forced by emissions and noise rules and the need for a four-valve engine. Its development was shared with the Boxster, which saved Porsche about 30 percent of the development cost at a time of financial trouble.
