718 BOXSTER/CAYMAN: All-new powertrains are the significant differentiator between '16 and '17. Gone are the normally aspirated six-cylinder Porsche powerplants, and in their place are two new turbocharged fours in 2.0-liter (Boxster/Cayman) and 2.5-liter (Boxster S/Cayman S) form. Beyond the drivetrains it's tweaked sheetmetal and improved handling for the droptop Boxster and Cayman coupe derivatives.
911: Like its smaller Boxster/Cayman sibling, the newest 911 Carrera and Carrera S forgo normally aspirated powertrains for the benefits of turbocharging. Unlike the Boxster and Cayman, they retain their six-cylinder configurations; with 3.0 liters of displacement the Carrera delivers 370 horsepower, while the higher spec Carrera S provides 420 hp. Beyond the power, Porsche Active Suspension Management is standard across the lineup, and the Porsche Communication Management infotainment system is enhanced.
PANAMERA: An all-new Panamera is introduced for 2017. Changes include two new engines (a 2.9 liter twin-turbo V6 for the Panamera S and 4.0 liter twin-turbo V8 for the Turbo), in combination with an all-new chassis, sheetmetal and interior.
CAYENNE: Porsche's first SUV received two significant updates for '17: An upgrade to the latest generation of Porsche Communication Management (PCM) infotainment/navigation system, first introduced in 2017 911 models, is installed in Porsche's largest crossover. And a Platinum Edition and Cayenne S E-Hybrid Platinum Edition are added to the lineup; both will help sustain Porsche as the world's most profitable automaker.
MACAN: The newest entry in Porsche's compact crossover lineup is the base Macan, boasting the only four cylinder in the Macan family as a complement to the other models, which have turbocharged V6s in various states of displacement and tune. The turbo four delivers 252 horsepower and 273 lb-ft of torque, propelling the Macan from 0-60 in 6.3 seconds. It also boasts a 200-pound weight advantage over the Macan S, and is some $5,000 less expensive.
