Porsche 911 review - engine, gearbox and technical details
Engine range comprises a pair of turbocharged 3-litre flat-sixes, with either an eight-speed PDK or no-cost option seven-speed manual
As the 992 has matured in the market, so too has the range expanded in both powertrain and body style. Currently there are two Carrera options with and without all-wheel drive (both now share a single body-in-white) plus the new top-tier Turbo and Turbo S. Each are then multiplied by hardtop and Cabriolet versions, with Carrera 4 and 4S models also available as a Targa. Carrera S models of any body shape are available with either a seven-speed manual or eight-speed PDK, while all other powertrains exclusively feature the PDK. Get it?
The Carrera’s 3-litre twin-turbocharged flat-six with 380bhp and 332lb ft, and the Carrera S’s 3-litre twin-turbocharged flat-six with 444bhp and 391lb ft. The latter figures, for reference, are very similar to the output produced by the old 991 Carrera GTS (and comfortably above the 996 Turbo’s – how times have changed).
Carrera 4 and Carrera 4S models use all-wheel drive, but all 992s currently use an eight-speed PDK dual-clutch gearbox, controlled as ever by a pair of paddles behind the steering wheel and via a new and curiously small transmission selector on the centre tunnel.
The 992s also feature petrol particulate filters in the exhaust system for the first time, helping to meet Euro 6 emissions regulations, but elsewhere it’s business as usual: suspension is by MacPherson struts up front with a multi-link rear axle, and the rack and pinion steering is electrically assisted. The wheel and tyre set-up is staggered: 19 and 20 inches on the Carrera, 20 and 21 on the Carrera S.
The 992’s structure though is more aluminium-intensive this time around. Only 30 percent of the shell is now steel, and the main body pressing is aluminium. There’s only one body shape, in contrast to previous 911s, which means two-wheel-drive models are now the same width as all-wheel-drive cars. The two-wheel-drive Carrera weighs in at 1505kg, the Carrera S 10kg more, all-wheel-drive models another 50kg, and Cabriolets an additional 70kg.
Turbo models have switched over to a new engine for the latest generation, drawing its base in Carrera S’s architecture, but with a larger 3.8-litre capacity, two variable geometry turbos and a completely different intake and cooling system. The Turbo models typically have much bigger numbers, with the standard Turbo running 572bhp and 552lb ft of torque, with the flagship S featuring a big jump to 641bhp and 590lb ft.
