A 600bhp Porsche Cayenne Turbo with £90,000 of modifications and a top speed of 200mph is for sale on Auto Trader.

This 2004 Porsche Cayenne (like the one pictured) has been tuned by German outfit Gemballa with power upped from 500bhp and 516lb/ft of pulling power to 600bhp and 634lb/ft, making it more powerful – and faster – than many supercars.

The power upgrade to the 4.8-litre Porsche Cayenne has been made possible by fitting an upgraded Super Sound exhaust system, modifying the air intake and uprating the turbocharger.

As a result, the Gemballa-tuned Porsche Cayenne Turbo will accelerate from 0-62mph (100kph) in 3.95 seconds and 0-124mph (200kph) in 15.8 seconds before hitting a claimed top speed of 200mph – just 1mph less than the iconic Ferrari F40.

Inside, the 200mph Porsche Cayenne Turbo has a full carbon fibre interior trim, black heated leather seats, racing dials, sat-nav, all-round electrics and driver and passenger airbags.

The Porsche Cayenne went on sale in 2003 and was one of the most controversial looking cars of the last ten years, with many not liking the jacked-up Porsche 911 styling.

Gemballa is a company based 12 miles from Porsche’s headquarters in Stuttgart. With 40 members of staff, Gemballa has been modifying Porsches for more than 25 years, using its expertise on the likes of the Porsche 911 Turbo, Cayman and Carrera GT hypercar.

This titanium-coloured Gemballa-styled Cayenne Turbo features a more aggressive bodykit with larger air intakes to cool the engine, while huge alloy wheels house the monster disc brakes.

In 2004, this Porsche Cayenne cost £70,000 new, but after 35,000 mile and a £90,000 Gemballa conversion, you can get your hands on it for just £79,995 making it one of the cheapest 200mph cars on the market.
