New Porsche Panamera GTS takes to the track The new Porsche Panamera GTS is the latest Panamera variant to arrive – the ninth Panamera, no less – and is, as all Porsche GTS models are, a harder-edged take on the more mainstream variants. With its naturally aspirated 4.8 litre V8 producing 425bhp, and pushing those horses through a PDK ‘box to all four wheels, the Panamera can scoot to 62mph in a very respectable 4.5 seconds on its way to a top speed of 179mph. Not bad for a big saloon car that eschews forced induction and can carry proper-sized passengers in comfort.
