New Porsche 911: T-Hybrid for significantly enhanced performance

Porsche has fundamentally upgraded the iconic 911 sports car. The new 911 Carrera GTS is the first street-legal 911 equipped with a super-lightweight performance hybrid. The 911 Carrera will also be available immediately upon the launch of the new model.

The newly developed, innovative powertrain system, with 3.6 litres of displacement (911 Carrera GTS (provisional values): Fuel consumption* combined (WLTP) 11.0 – 10.5 l/100 km, CO₂ emissions* combined (WLTP) 251 – 239 g/km, CO2 class G ), delivers significantly improved driving performance. The 911 Carrera GTS Coupé accelerates from zero to 100 km/h in 3.0 seconds and reaches a top speed of 312 km/h.

The 911 Carrera will also be available immediately upon the launch of the new model. It is powered by a lightly modified 3.0-litre twin-turbo boxer engine (911 Carrera: Fuel consumption* combined (WLTP) 10.7 – 10.1 l/100 km, CO₂ emissions* combined (WLTP) 244 – 230 g/km, CO2 class G ) that is more powerful than its predecessor’s. The new 911 also features a revamped design, better aerodynamics, a fresh interior, upgraded standard equipment and expanded connectivity.

With the relaunch of its iconic model, Porsche has modernised four of its six model lines in just a few months: Panamera, Taycan, Macan and 911. “Our product portfolio is younger than ever and highly attractive,” says CEO Oliver Blume. “It offers our customers even more customisation options and exclusive experiences.”

Inspired by motorsport: innovative performance hybrid

For the new 911 Carrera GTS models, Porsche’s engineers used knowledge gained from motor racing as the basis for designing the hybrid system. “We developed and tested a wide variety of ideas and approaches to arrive at the hybrid system that would suit the 911 perfectly. The result is a unique drive that fits into the overall concept of the 911 and significantly enhances its performance,” says Frank Moser, Vice President Model Lines 911 and 718.

The lightweight and powerful T-Hybrid system has a newly developed electric exhaust gas turbocharger. An integrated electric motor, placed between the compressor and turbine wheel, instantaneously brings the turbocharger up to speed. This immediately builds up boost pressure. The electric motor in the exhaust gas turbocharger also functions as a generator. It generates up to 11 kW (15 PS) of electric power. This energy is extracted from the exhaust gas flow. The wastegate-free electric turbocharger allows the use of only one turbocharger instead of the previous two, which ensures a more dynamic and responsive power delivery.

The powertrain also includes a permanent magnet synchronous motor integrated into the new, more powerful eight-speed dual-clutch transmission (PDK). Even at idle speed, it supports the boxer engine with extra drive torque of up to 150 Nm and provides a power boost of up to 40 kW. Porsche couples both electric motors to a lightweight and compact high-voltage battery. It corresponds in size and weight to a conventional 12-volt starter battery, but stores up to 1.9 kWh of energy (gross) and operates at a voltage of 400 V. For an optimised overall weight, Porsche has installed a lightweight lithium-ion battery for the 12 V on-board electrical system.

The heart of the T-Hybrid drive is a newly developed 3.6-litre boxer engine. The high-voltage system allows the air-conditioning compressor to be driven electrically and the belt drive to be omitted as a result, making the engine much more compact. This creates space above the power unit for the pulse inverter and DC-DC converter.  An enlarged bore of 97 mm and an increased stroke of 81 mm increase the displacement by 0.6 litres compared to its predecessor. The engine has VarioCam camshaft control and a valve control with rocker arms. It maintains the ideal mixture ratio of fuel and air over the entire map (lambda = 1).

Even without electrical assistance, the boxer engine delivers 357 kW (485 PS) and 570 Nm of torque. In total, the system output is 398 kW (541 PS) and 610 Nm. The power increase over its predecessor is 45 kW (61 PS). The new 911 Carrera GTS also beats its predecessor in the sprint to 100 km/h, particularly off the line. The efficient performance hybrid achieves highly dynamic driving characteristics while at the same time reducing CO₂ emissions with significantly less extra weight compared to plug-in hybrid vehicles. The weight increase over its predecessor is a mere 50 kilograms.
