Porsche will initially launch two versions of its Cayenne SUV late this year. Entry-level model will be the £60,000 Cayenne S, powered by a 340bhp, naturally-aspirated version of Porsche's 4.5-litre V8.

Top of the range will be the £80,000 Turbo, which has 450bhp and will sprint from 0 to 60mph in 5.6 seconds and reach 165mph. Innovations include single switch control for ride height, torque split and a low ratio first gear.
