It was just last week that we brought you spy shots of a production-ready 911 Turbo S prototype being tested. The tester was wearing minimal camouflage leaving little to imagination. Porsche has now officially revealed the next-generation 911 Turbo S as the quickest and most powerful 911 Turbo model ever. With 640 horsepower and 800Nm of torque put out by the 3.8-litre turbocharged boxer engine paired with a Turbo-specific eight-speed PDK transmission, the range-topping 992 Coupe goes from 0-100kph in just 2.7 seconds (2.8 seconds for the Cabriolet). The 911 Turbo S Coupe reaches 200kph from standstill in just 8.9 seconds and the top speed for both the variants is 330kph.

The new 911 Turbo S is wider than its predecessor and Porsche says the modified track widths, along with optimised aerodynamics, and new tyres help the Turbo models with greater agility and sportiness. Contributing to enhanced aerodynamics are adaptive cooling air flaps at the front, and a larger rear wing designed to provide even more downforce. For the first time, the 911 Turbo S transfers its power to the road using staggered centre-lock wheels in two different diameters -- 20-inch wheels at the front are wrapped in model-specific 255/35 tyres, and the 21-inch rear wheels get 315/30 rubbers.

The new 911 Turbo S models get two new factory options not available on the previous generation, Porsche Active Suspension Management (PASM) Sport suspension with a ride height lowered by 10 mm compared to the standard PASM suspension, and the Sport Exhaust System with adjustable exhaust flaps and distinct oval tailpipes that give out a characteristically distinctive note. Porsche Dynamic Chassis Control, rear-axle steering and Porsche Ceramic Composite Brakes, now with 10-piston front callipers, are standard. The front brake rotors are larger by 10 mm at 420 mm.

Porsche says the new generation of the standard PASM chassis has also been retuned to offer even better handling. It claims faster and more precisely controlled dampers will provide better roll stability, road holding, steering behavior and cornering speeds. Wet Mode is standard, detecting water on the road, automatically preconditioning stability control and anti-lock brake systems accordingly, and warning the driver.

The new front end with wider air intakes, combined with dual front light modules and standard LED Matrix-design headlights with dark surrounds lend the 911 Turbo S models a distinctive front fascia. The redesigned, pneumatically extendable front spoiler and the larger rear wing result in 15 per cent more downforce compared to the previous model. The muscular rear fenders with integrated air intakes and rectangular tailpipes in high-gloss black, round off the brawny looks of the 911 Turbo S at the back. The optional Sport Exhaust System is distinguished by oval tailpipes that can be ordered in high-gloss Black or Silver finish.

The cabin gets full leather and carbon fibre trim in combination with Light Silver accents as standard. Also standard are 18-way adjustable sports seats that carry stitching patterns reminiscent of those on the first 911 Turbo, the type 930. The centre touchscreen on the dashboard now measures 10.9 inches, while a GT Sport steering wheel, Sport Chrono package with newly integrated Porsche Track Precision app and the Bose Surround Sound system are also standard equipment.

The 2021 Porsche 911 Turbo S Coupe will be priced at $203,500 (Dh747,500), while the 911 Turbo S Cabriolet will retail for $216,300 (Dh794,500). Both models will be available to order soon and are expected to reach dealerships later this year.
