The 993 Turbo coupé was introduced in 1995. It featured a new twin-turbocharged engine displacing 3.6 liters and generating a maximum power output of 402 hp. Air-to-air intercoolers, electronic engine management, redesigned cylinder heads and other modified engine internals completed the new engine. The 993 Turbo was the first 911 Turbo with all wheel drive, taken from the 959 flagship model. The electronic engine management helped the Turbo to achieve fuel efficiency far superior to its predecessors.
