Like a junky craving speed, the Mission 400 Plus project (that’s 400 for in kph or 248 mph) sponsored by H&R is attempting a new world record come 2007 with their slick 997 Turbo. RS Tuning are saucing up the motor to 1,054hp while Jurgen-Alzen Motorsport are heading the technical design and overall build for the Nardo top speed operation. This car’s debut was at Essen, though it’s a prototype we can guess that it’ll be the car to do it. Why?
H6 motor bored to 3.8L from 3.6L.
The roof has been cut down by 3 inches.
The A-pillars are tilted back by 5.5 degrees.
Sans side mirrors!
18-inch BBS light-alloy LM-Rs

World Fastest? What class?
Street legal i guess.
H&R wants this car to hit over 248 mph AND be street legal. The Koenigsegg CCR beat the McLaren F1 (231 mph) at Nardo when it hit 241 mph. Insane!
