Model strengths: Iconic design with a fresh spin; exceptional agility; top-level engine performance; available all-wheel drive; open-roof options; surprising fuel efficiency.

Model changes: For 2017 there are minor changes are made to styling and features, a new 3.0L twin-turbocharged engine replaces last year’s 3.4L engine. 911 Turbo models gain the Sport Chrono Package and Dynamic Boost function as part of their standard equipment. All 911s gain Porsche Active Suspension Management (PASM), while options such are rear axle steering and Apple CarPlay make the option’s list.

Model value: In the world of high-end sports cars, the 911 is arguably the most iconic model in history. Though the design has continued to change over the last 50 years, the fundamentals are still in place: rear-mounted flat-6 engine and a precision chassis developed with handling in mind.

Together, the components add up to a sports car that’s hard to beat both in terms of aesthetics and performance. The 911’s a capable competitor to other sport coupes such as the Aston Martin V8 Vantage, Audi R8, BMW M3 and Nissan GT-R.

Carrera S, Carrera 4S and Targa 4S buyers get a slightly larger 3.8L flat-6, which makes between 370 and 450 horsepower.

The GT3, the GT3 RS, the Turbo and the Turbo S all use different versions of this same 3.0L engine, making different power in each variant. In the GT3 it makes 475 horsepower, while the GT3 RS makes 500. The addition of two turbochargers brings horsepower up to 520 and 560 for the Turbo and Turbo S, respectively.

All engines are mated to a standard 7-speed manual transmission. The 7-speed PDK double-clutch automatic is optional, and standard on the Turbo S, the GT3 and the GT3 RS. In the manual, the ratios are close together in every gear except 7th, which helps to achieve a better fuel consumption rate during highway use.

Other features include electric power steering and a hydraulic decoupler of the front and rear sway bars, known as Porsche Dynamic Chassis Control. In addition, 911s feature a rear-wheel torque vectoring system that helps build traction using the rear brakes in conjunction with the rear differential.
