The revised Porsche Panamera Turbo S has been revealed, and is pictured here for the first time.
Porsche has raised the already imposing performance potential of the Turbo S, giving the facelifted model a 20bhp boost in reserves to take the output of its twin-turbocharged 4.8-litre V8 up to 562bhp – 49bhp more than the recently introduced facelifted Panamera Turbo.
To be revealed to the public at the upcoming Tokyo motor show prior to the start of UK sales in February 2014, the range-topping Panamera model adopts the various exterior and interior styling upgrades brought to other less powerful Panamera models earlier this year.
Included in the mid-life make-over is a new front bumper with larger air intakes and redesigned head lamps with LED operation.
Bigger changes are concentrated at the rear, which receives a larger rear window within the tailgate along with a colour-keyed four-way spoiler and a new bumper which now houses the licence plate.
Together with the standard model, Porsche now offers the Panamera Turbo S in Executive form with a 150mm longer wheelbase in selected markets, both running 20-inch 911 Turbo-style wheels shod with 285/40 and 295/35 profile tyres as standard.
At the heart of the facelifted Panamera Turbo S is a lightly revised version of its predecessor’s twin-turbocharged 4.8-litre V8. It gains new turbochargers boasting a larger compressor for improved air flow and combustion.
Further changes are concentrated on the injection system, which now operates at a pressure of 140 bar – up from a previous 120 bar. New pistons and piston rings featuring a newly developed aluminium coasting are also used.
