Mounted in the rear of the 911 is a twin-turbo 3.0-liter flat-six-cylinder engine. The base Carrera has 379 horsepower, the S pumps out 443 ponies, and the GTS generates 473 horses. While every model comes standard with a ridiculously quick-shifting eight-speed automatic transmission, a sweet seven-speed manual is offered on the S and GTS. The coupe and cabriolet have standard rear-wheel drive, but they can be fitted with all-wheel drive for four-season, high-performance driving. The Targa is all-wheel-drive only. We’ve tested the base Carrera as well as several variations of the more powerful Carrera S, which proved its prowess at the racetrack and its incredible traction in adverse weather conditions. No matter the application, every 911 has astonishing acceleration, especially when the gleefully good launch control is utilized. At our test track, the GTS model bolted to 60 mph in just 2.8 seconds when equipped with the eight-speed automatic; with the seven-speed manual, the 911 GTS delivered a slightly slower 3.2-second result in the same test. Porsche’s optional sport exhaust system also helps enhance the experience by providing a fuller engine note. Best of all, the 911 is as comfortable as ever and also better to drive. Its steering is communicative and brilliantly direct, and the coupe and convertible have increased cornering grip and stability. The ride quality is surprisingly supple, too, despite the 911’s amazing body control, which allow drivers to seamlessly switch between relaxed and spirited romps.
