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.
Lightweight construction
The advantages of an alloy engine are its low weight and reduced fuel consumption.
Thanks to intelligent design down to the finest detail, it has been possible to reduce the weight of the new generation of engines even further, e.g. by fully integrating the camshaft bearings into the cylinder heads.
Fuel economy has been further improved by the optimally designed oil supply system and a reduction in the mechanical friction of the engine.
Exhaust system
The stainless steel exhaust system comprises two independent and separate exhaust tracts. Its catalytic converters are highly temperature-resistant and heat up rapidly for effective emissions reduction.
Thanks to advances in emissions technology, they are able to meet strict emission standards, such as EU5 in Europe and LEV II in the USA.
Using stereo lambda control, two sensors continuously monitor the exhaust gas composition for each exhaust tract. A further sensor monitors the efficiency of the catalytic converters.*
In addition, a sports exhaust system is available as an option. This can be activated as desired using a button on the center console. If fitted in conjunction with the optional Sport Chrono Package Plus, the sports exhaust system is activated automatically when ‘Sport’ mode is selected.
