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.

Making their debut halfway into the model year are the Turbo convertible and the Targa versions. The former is as you'd expect: the Turbo in the convertible body style. But the latter is noteworthy in that it mimics the style and function of the classic 911 Targa. Rather than having a big, framed glass sunroof that slides rearward over the rear hatch glass (like the most recent Targas), the 2014 version has a large, frameless roof panel that powers out of sight behind the rear seats, providing a more open cabin. It also features the iconic brushed aluminum "Targa bar" and wrap-around rear window that recall the handsome style of the earlier Targas.
