The new 2017 Porsche 911 Targa 4 feature more powerful engines with better efficiency and a new all-wheel drive system. The 2017 911 Targa 4 features newly developed, powerful and fuel - efficient three liter twin-turbo flat six engines that can also be found in the rear-wheel drive 911 Carrera models. Power distribution to all four wheels is now handled by Porsche Traction Management (PTM ) with electrohydraulic control, adopted from the 911 Turbo.
Over one third of all Porsche 911 buyers choose a model with all-wheel drive. The new 911 Targa 4 now offers added performance and comfort characteristic of the latest 911 generation. The innovative turbo engines have higher power outputs and consume less fuel, and the enhanced all - wheel drive system boosts driving performance and safety. The standard adaptive PASM suspension with a 0.39 inch (ten millimeter) ride height reduction compared to the previous standard 911 Carrera and Targa models offers an even greater spread between performance and ride comfort. Rear axle steering – now available as an option in the 911 Targa 4S model for the first time – improves handling and performance even further. Inside the car, the new standard Porsche Communication Management (PCM) system offers extended functionality. It features online navigation, more connectivity and smartphone-like operation via a multi-touch screen.
