German-tuned Crossfire gets performance to match appearance Startech—sister company to German tuner Brabus—is giving the Chrysler Crossfire the sort of performance its aggressive appearance suggests. Shoehorned under the hood of the heavily reworked two-seater revealed in Frankfurt is a 6.1-liter V8 based on the 5.0-liter V8 used in the Mercedes-Benz S-Class. In this guise, the three-valves-per-cylinder unit delivers 426 hp at 5400 rpm along with 449 lb-ft of torque at 4100 rpm. That’s up 208 hp and 225 lb-ft on the Crossfire’s standard 3.2-liter V6 and enough, according to Startech, to give the car 0-to-62-mph acceleration in 4.7 seconds and a top speed of 186 mph. Beefier suspension, bigger brakes and a larger automatic rear wing help the car cope with the added power. Base price for the car and modifications is a cool $107,000.
