Porsche has added a new bodystyle to its Panamera range - revealing the more spacious Sport Turismo. The new model is based on the sports saloon, yet is more versatile with an increased luggage compartment of up to 570 litres - thanks to a raised roof line and larger tailgate. The new model will be available with five engines borrowed from the sports saloon, offering up to 550 bhp. The new Porsche Panamera Sport Turismo is set for market launch in October.
