NEW FOR 2010: - Redesigned Turbo with new engine and drivetrain - New, more powerful GT3 model - New GT3 RS model - Exterior colours: Dark Blue added; Midnight Blue discontinued For 2010, the Porsche 911 Turbo is redesigned, with a major styling refresh, and an entirely new drivetrain with a 3.8-litre six-cylinder turbocharged engine that replaces the previous 3.6-litre turbo; the optional automatic transmission is now a seven-speed PDK double-clutch transmission in place of the previous five-speed automatic. The GT3 also gains a new 3.8-litre engine and styling, and an even more powerful RS version. The wide-ranging 911 family encompasses 15 models: the Carrera and Carrera S, in coupe or convertible; the all-wheel drive Carrera 4 and Carrera 4 S, in coupe or convertible; Targa 4 and Targa 4 S; Turbo and Turbo Cabriolet; and GT2, GT3 and GT3 RS. All engines are six-cylinder and horizontally-opposed. A 3.6-litre, 345-horsepower engine is used in the Carrera, Carrera 4, and Targa 4, while a 3.8-litre, 385-horsepower version is used in the Carrera S, 4 S and Targa 4 S. The Turbo models use a turbocharged 3.8-litre. The GT3 uses a naturally-aspirated 3.8-litre making 435 horsepower, while the GT3 RS uses the same engine but coaxes out 450 horses. The GT2 uses a turbocharged 3.6-litre for 530 horsepower and is race-ready but street legal. The “4” designation on models indicates all-wheel drive. All models use a six-speed manual transmission that can be optioned to a seven-speed PDK double-clutch transmission in everything but the GT3, GT3 RS and GT2 models, which are strictly stick-shift. Features on the Carrera include 18-inch alloy wheels, automatic climate control, four-piston calipers with ventilated brake discs, hydraulic power-assist steering, bi-xenon headlamps with washers, head and thorax side airbags, anti-theft system with interior sensor, keyless entry, heated mirrors, bi-xenon headlamps, Porsche Stability Management system, rain-sensing wipers with heated washer nozzles, tire pressure monitoring system, three-spoke leather-wrapped steering wheel, on-board computer, heated seats with power-adjustable backrest, storage shelf, lockable glovebox and storage compartment, Porsche Communication Management with 5.8-inch colour display, Bose Surround Sound CD stereo, garage door opener, cruise control, illuminated vanity mirrors, black instrument dials, power windows, Alcantara headliner, and automatic extending rear spoiler. The Coupe includes a power-operated sliding steel sunroof, while the Cabriolet adds a power top and safety bars. The all-wheel drive Carrera 4 and Carrera 4S models have corresponding features (S models use 19-inch wheels), while the Targa models include a glass roof made from two large panels running from the windshield to the engine cover. The transparent glass absorbs almost all ultraviolet radiation and does not transit heat into the vehicle; the front portion can be opened electrically, and the roof includes an integrated power shade. The Turbo models add 19-inch alloy wheels, all-wheel drive, red six-piston calipers, enhanced Porsche Stability Management system, auto-dimming side and rearview mirrors, Sport Chrono package, electrically-adjustable seats with driver’s side memory, full leather interior, navigation system, and aluminum-colour instrument dials.
