- TECHART GTstreet Convertible

For those of you who are lucky enough to be able to afford a Porsche 911 Turbo Cabriolet yet are not satisfied with the 480 HP of the stock 3.6-liter biturbo boxer engine, German tuner Techart has announced that it will reveal a supped up version of the car at next month’s Geneva Motor Show. The GTstreet convertible’s tuned boxer engine generates a whopping 630 HP allowing it to reach a maximum speed of 345 km/h or 215 mph. More details on the car will be released at the Geneva Show.
