Powering the new 911 GT3 is a water-cooled six-cylinder Boxer engine with four-valve technology and enhanced VarioCam variable valve timing. It generates 320 kW (435 hp) from a total displacement of 3,797 cm3. The maximum torque is 430 Nm. The maximum engine speed is
The new 911 GT3 reaches 100 km/h (62 mph) in just 4.1 seconds, with a top speed of 312 km/h (194 mph). The weight-to-power ratio is 3.2 kg per hp and the new engine provides an output of 115 hp per litre.
In short: the popularity of the new 911 GT3 is assured due to this increase in power, yet similar fuel consumption.
This efficiency is demonstrated by the vehicle’s compliance with the stringent requirements of the Euro 5 emissions standard.
A consistent supply of oil to the engine, even at times of high lateral acceleration, is ensured by a dry sump lubrication system with an external engine oil reservoir. The oil is cooled by an oil-water heat exchanger. Both of these systems have proven themselves on the racetrack.
An extremely lightweight titanium connecting rod and lighter pistons reduce oscillating masses, thus ensuring dynamic engine speed development. The inlet and exhaust valves are actuated by extremely lightweight tappets and hydraulic valve clearance adjustment. This enables a maximum engine speed of 8,500 rpm which, together with the short sporty gear ratios, provides plenty of performance potential.
Added to this is a variable intake manifold with two resonance valves which work together with the sports exhaust system to ensure efficient cylinder charging and high throughput rates. The large volume of the exhaust system supplements the low-resistance intake manifold to improve cylinder charging and increase performance.
The development of the new engine. A challenge as always. Which is why it is proof of our core values.
* These data were obtained using the Euro 5 measurement method (715/2007/EC and 692/2008/EC) in the NEDC (New European Driving Cycle) with standard equipment. The information does not refer to an individual vehicle and is not part of the offer, but is simply provided so that comparisons can be made between different types of vehicle.
