Performance
The latest 911 has a new generation of engines with direct fuel injection (DFI), and significantly more power. 345 hp is generated by the 3.6-liter boxer (horizontally-opposed cylinder) engine and 385 hp by the 3.8-liter power unit.
The results are outstanding performance and increased fuel efficiency and emission values. All made possible thanks to DFI, VarioCam Plus, an improved lightweight construction, reduced friction and a number of detailed technical solutions.
Braking system
Porsche brakes are renowned for their stopping power, setting the standards for deceleration and stability. They are designed to cope with extreme forces such as those experienced during hard braking.
The brake calipers have a monobloc aluminum construction. This makes them tough but light and enables a rapid response and release of the brake. The pedal travel is short and easy to modulate.
On the 911 Carrera models, the front and rear axles are host to a new generation of brakes with anodized black, four-piston aluminum monobloc calipers. The brake calipers are now even stiffer thanks to their closed-type design. The brake disc diameters are larger: 330 mm front and rear and the rear brake discs are 4 mm thicker – for even better braking performance.
The S models have four-piston aluminum monobloc calipers that are larger, reinforced and have a striking red painted finish. The front axle has larger brake pads and thicker brake discs.
All models have cross-drilled brake discs ensuring optimum braking in the wet. The discs are internally vented for rapid heat dispersal.
Other features include a powerful 10-inch brake booster for reducing pedal effort in the rear-drive models and integral air spoilers for enhanced air flow in the brake cooling ducts.
For even better braking performance with braking force support, a 9-inch tandem brake force amplifier is used on the all-wheel drive models.
Steering
The power steering is sensitive and precise, providing excellent contact with the road and minimal steering effort by sportscar standards. It offers steering precision comparable with a racecar – even on those relaxing drives.
A special feature is the variable steering ratio. Around the straight ahead position, such as during motorway driving, the ratio is less direct. The risk of losing control of the wheel at high speed is reduced, with no loss of agility or feedback.
When the steering wheel is turned harder, the ratio becomes more direct, allowing for easier cornering and parking. The car has a turning circle of just 10.9 m.
