This new Turbo S model is the fastest, most powerful variant of the Porsche Panamera yet.
The twin-turbo 4.8-litre V8 super-saloon has had a power hike over the Turbo model on which it is based, from 493bhp to 542bhp, taking it beyond its Mercedes S63 AMG (518bhp) and BMW 760Li (537bhp) rivals. The Turbo S’s top speed is 191mph, 3mph higher than the standard Turbo, while its 3.8sec 0-62mph time makes it quicker than a 911 GT3 RS (4.0sec).
Porsche engineers have fitted titanium-aluminium turbine wheels to the turbochargers and revised the engine control management of the Turbo S to boost power and performance. Torque is also up in the S over the standard Turbo, from 510lb ft to 553lb ft when driven in Sport and Sport Plus modes, and up to 590lb ft is available with an overboost function.
These increases have been made without sacrificing economy, which stays at 24.6mpg combined, due to the lighter weight and lower inertia of the turbine and compressor wheel in the turbochargers.
