It was only a matter of time before Porsche started selling a 911 Turbo based on the 992-generation car, though this time the automaker launched the flagship with the Turbo S, announced today with 640 horsepower and the ability to crush zero-to-60 miles per hour in just 2.6 seconds, storm the quarter mile in 10.5 seconds, and top out at 205 miles per hour. Let’s all remember not too long ago the Carrera GT supercar had a top speed of 205 mph, though it was slower in all other regards.

Both coupe and Cabriolet models are available, though expect the 0-60 mph time in that car to be a slightly slower 2.7 seconds. We also presume the “regular” 911 Turbo to join the Turbo S down the line.

Though it looks similar to the previous 991 generation and uses the long standard 3.8 liters of displacement, the Turbo S engine is a new development of the flat six in the Carrera S. Much is different to boost power, but it does take some cues from the turbocharged Carrera S, such as Piezo injectors and turbines that spin in opposite directions. Those two variable geometry turbos are bigger than in the old Turbo S (and, of course, those in the Carrera S) and now have electrically adjustable wastegate flaps.

The most radical change in the engine seems to be the approach to the air intake and intercooler placement. The intercoolers now cool charged air from behind the flat six instead of the openings in front of the rear fenders. Those openings now feed air to the engine intake, while the two intakes below the rear spoiler supply air to the intercoolers. Porsche says the intercoolers are 14% larger than in the previous Turbo S and that cool air flow has increased by 13%.

The Turbo S gets staggered-diameter wheels for the first time, measuring 20 inches up front and 21 inches at the rear. Tires are sized 255/35 and 315/30, respectively. The car also is wider than before, by 1.8 inches at the front axle and 0.78 at the rear, which in turn means a 1.65-inch wider front track and 0.39-inch wider rear track. These changes all increase grip, traction, stability, agility.

Also helping the handling are standard rear axle steering, active anti-roll bars, and ceramic composite brakes, which also improve braking and virtually prevent brake fade. The Turbo S now comes standard with 10-piston front calipers.

Two new options on the Turbo S appeal to the performance-minded buyer: an active sport exhaust and PASM Sport, a more performance-and-handling oriented suspension system than regular PASM with active dampers.

Visually the Turbo S is distinct from the Carrera lineup with larger front air intakes, LED headlights with dark surrounds, a redesigned extendable front lip spoiler and larger rear wing (which increase downforce by 15%), and gloss-black rectangular exhaust pipes. Cars equipped with the optional sport exhaust get ovular pipes in either gloss black or silver.

Inside, full leather is standard as well as carbon-fiber trim, 18-way adjustable Sport Seats Plus, and GT Sport steering wheel, Sport Chrono, and a Bose sound system.

The 911 Turbo S coupe will cost $203,500, while the Cabriolet will be a bit more at $216,300, not including $1,350 delivery, processing, and handling fee. They’re expected to arrive in dealer showrooms in late 2020.
