► The Porsche Turbo S, now in 992 form
► 641bhp and four-wheel drive
► The best 911 'til the GT models arrive
You’re looking at the new 911 Turbo S, just revealed via online stream instead of the Geneva motor show. The new range-topper for the new 992 – at least until the GT models get here – the Turbo S produces 641bhp from a forced-induction 3.8-litre flat six. It’ll come in Coupe and Cabriolet forms, both of which we’ve already spied testing earlier this year.
Tell us about the engine?
Unlike the Taycan Turbo S, this Porsche turbo actually has twin-turbochargers, and straps them to a new 3.8-litre engine block. Part of the power gain comes from larger turbochargers with Variable Turbine geometry: the turbine wheels are now five millimetres larger at 55 mm, and the 61mm compressor wheel is three millimetres larger than before. The wastegate flaps are electronically controlled now, for faster response times.
Even the layout of the turbochargers themselves is different for the 992 Turbo S: they now sit symmetrically, rotating opposite ways. Throw in piezo fuel injectors like we’ve seen elsewhere in the new 911 range, and power and torque – as well as efficiency – is all up on last gen’s model.
So how powerful, and how quick?
There’s a handsome increase in power: 641bhp is 69bhp more than the 991.2 Turbo S, and at 580 lb ft, the torque is up by 37 lb ft.
To cope with the extra power, Stuttgart’s engine bods have rethought the cooling philosophy for the new 992 Turbo S. Porsche Dynamic Chassis Control, along with PASM all-wheel drive also means the 911 can put some of that power down efficiently: 369 lb ft of torque can be diverted to the front axle if needed.
New Porsche 911 Turbo S prototype review
It’s all mated to an eight-speed PDK box, which promises a 0-62mph dash of 2.7 seconds (0.2 seconds faster than last time around) and 0-120 mph in just 8.9 – one second faster than the 991.2. Top speed is an autobahn-crushing 205mph.
It looks like a Turbo...
The Turbo S badge means this 911’s hips have grown by 20mm to 1900mm. The track is 42mm rider and the front axle and 10mm at the rear, too – both promising increased grip and agility on the roads. The Turbo S rolls on 20-inch 255/35 wheels on the front axle, and 21-inch 315/30 wheels on the rear – and there’s a new centre-lock design for the alloys.
Aero grip is equally important for the 992 Turbo S: downforce is up 15% thanks to a reworked, saucer-like rear wing, and active aero in the front spoiler.
Alongside the extra girth, the new 911 Turbo S features all the hallmarks of Stuttgart’s range-topper. Additional rear and wider front air-intakes, a pair of squared-off dual exhausts and dual front-light modules mark this out as something other than standard 911.
So how much?
The 911 Turbo S Coupe will cost £155,970, while the Cabriolet will set you back £165,127. If that’s not quite maxing your budget, Porsche will also let you tick a length options list, which includes a 10mm lower sports chassis, and sports exhaust.
