For 2014, the new Turbo, Turbo S and GT3 models initially join the Porsche 911 lineup. Later in the model year, the Targa and the Turbo convertible variants further expand the family. To celebrate a half-century of 911s, there's also a 50th Anniversary edition.

For 50 years, the Porsche 911 has been the quintessential sports car. Through the decades, it has remained true to its roots as a serious performer, with enough refinement and innovation to appeal to more sophisticated drivers with deeper pockets. Rather than explode onto the scene with a completely reworked 911 every generation, Porsche's top sports car has evolved, edging ever closer to perfection.

The latest 2014 Porsche 911 lineup follows this tradition, providing stunning performance, decadent luxury and all-day comfort in a single package. This year, its performance threshold increases, as the new-generation 911 Turbo, Turbo S and GT3 models join the lineup. The new Turbo and Turbo S get a turbocharged 3.8-liter six-cylinder that belts out 520 horsepower in the Turbo and 560 hp in the Turbo S. All-wheel drive is again standard, though the Turbo models do have a new four-wheel steering system. Also new: Porsche is only equipping them with the seven-speed automated manual (PDK) transmission.

No disrespect to the Turbo S -- it's the fastest 911 on the lot -- but the GT3 is still the baddest Porsche on the block. This track-oriented model features a normally aspirated 3.8-liter six-cylinder good for 475 hp and a hair-raising 9,000-rpm redline. The new four-wheel steering system is used here as well, as is the PDK transmission (specially tuned for GT3 use). Note that PDK is standard -- this is the first Porsche 911 GT3 not offered with a conventional manual gearbox.
