It's been nearly a year and a half since the all-new 2020 Porsche 911 Carrera was presented to the world at the 2018 LA Auto Show. Now, Porsche is finally ready to expand the 992-generation 911 series with the new range-topper. Meet the all-new 2021 Porsche 911 Turbo S Coupe and Cabriolet - the fastest and most powerful 911 Turbo model ever made.

At the heart of the 2021 Porsche 911 Turbo S is a 3.8-liter, twin-turbo flat-six engine producing 640 horsepower and 590 lb-ft of torque, an impressive increase of 60 hp and 37 lb-ft from its predecessor. The flat-six engine is paired with a model-specific eight-speed, dual-clutch transmission, enabling the new 911 Turbo to sprint from 0-62 mph in just 2.6 seconds (2.7 seconds for the Cabriolet). That makes it 0.2 seconds faster than the previous model. 0-124 mph takes 8.9, while the quarter-mile takes 10.5 seconds. Both Turbo S models will hit a top speed of 205 mph. Power is sent to all four wheels.

Compared to its predecessor, the new 911 Turbo S is around 1.8 inches wider at the front and is 74.8 inches wide at the rear axle, an increase of 0.78 inches. Modified track widths, optimized aerodynamics, and new tires also enhance the car's agility. The track is now 1.65 inches at the front axle and 0.39 inches wider at the rear axle, and Porsche has added adaptive cooling air flaps at the front.

Dominating the rear is a larger rear wing that provides 15 percent more downforce than the previous model. For the first time, the 911 Turbo S sits on staggered center-lock wheels in two different diameters: 20-inch wheels at the front are wrapped in model-specific 255/35 tires, while the 21-inch rear wheels use 315/30 tires. The front and rear tires are 0.39 inches wider than 2020 911 Carrera S models and previous 911 Turbo models.

To further increase the performance, Porsche is offering an 'Active Suspension Management Sport' system that lowers the ride height 0.39 inches compared to the standard setup and a sport exhaust system with adjustable exhaust flaps and oval tailpipes in gloss black or silver. As with the previous 911 Turbo S, Porsche's dynamic chassis control, rear-axle steering, and ceramic composite brakes (now with 10-piston front calipers) are standard. The size of the front brake rotors has also increased from 16.14 inches to 16.5 inches.

Inside the luxurious interior, standard equipment includes full leather and carbon fiber trim combined with light silver accents, 18-way adjustable sport seats with stitching patterns reminiscent of those on the first 911 Turbo, and unique graphics and logos in the instrument cluster.

Like the 911 Carrera models, the new 911 Turbo is equipped with a 10.9-inch central touch screen. Other standard features include a GT Sport steering wheel, a Sport Chrono package with newly integrated Porsche Track Precision app, and a Bose surround sound system.

Pricing for the 2021 Porsche 911 Turbo S Coupe starts at $203,500, while the 911 Turbo S Cabriolet will retail for $216,300. Prices exclude the $1,350 delivery, processing and handling charge. Both models will be available to order soon and will arrive in US dealers in late 2020.
