Open overdose: The new Porsche 911 Turbo Cabriolet
The two Turbo Cabriolets follow closely in the technical footsteps of their coupé equivalents, including the 3.8-litre 6-cylinder engine with either 520HP or – in the S model – 560HP. The 0-62mph sprint takes 3.5 and 3.2 seconds respectively, beating the two models' predecessors by a small but (at these performance levels) significant 0.2 seconds. Top speed is around 198mph (318 km/h) and both cars boast innovative rear-axle steering.
