Mazda’s MX-03 sport coupe concept was built on a 106.7-inch wheelbase, and at 177.5 inches long, was about the size of a Ford Taurus. The 4-seater had 4-wheel drive, 4-wheel steering, and antilock brakes. Power was supplied by a 3-rotor rotary engine that produced 320 horsepower and came mated to a 4-speed automatic transmission. Mazda reported that the MX-03 could streak from 0-to-60 miles per hour in 5-seconds and top out at 186 miles per hour.
