If the Porsche 911 Turbo with 493bhp isn't powerful enough for you, TechArt has developed a 'power kit' to take it to 690bhp.
Extra power comes from new turbochargers, intercoolers, manifolds and air cleaners. The whole thing is controlled by a re-programmed engine management system and the motor's appearance is enhanced with a TechArt engine styling package.
The result of these modifications is a claimed 0-62mph time of 2.8 seconds. Keep accelerating and 124mph will come up in 9.0 seconds with a top speed of 218mph.
