What is it?
Having driven the go-faster version of the Porsche Panamera Turbo abroad some time ago, we now get to experience the range-topper in the UK, where it adds £23k the standard model’s six-figure price. Chiefly, what that buys you is bragging rights.
Porsche has swapped out the two turbochargers on its V8 engine for those with an even healthy capacity for forcing air through the engine. With the pressure up by 20 bar, the pistons have been made from a new aluminium alloy to compensate.
The net result turns up the wick from 512bhp to 562bhp. The peak twist advantage is more slender – from 516lb ft to 553lb ft at 2250rpm – although full-throttle overboost takes it all the way to 590lb ft. Impressively, this hike in potency has apparently not harmed efficiency. Porsche has recorded the same optimistic 27.7mpg for the S as it did for the Turbo.
Elsewhere, most of Porsche’s favourite acronyms come fitted as standard. PASM, PDCC, PTV and PDCC (or active air suspension, active anti-roll bars, torque vectoring and ceramic brakes to you and me) are all on board, as are 20-inch wheels, sat-nav and a full-leather interior.
