The electric powered compressor delivers high starting performance. As well as very vigorous acceleration, the electric supercharger provides a repeatable boost function when accelerating. This means the EPC pre-empts any hint of turbo lag, and enables high responsiveness and powerful acceleration in every driving situation.
700 Nm (516.3 lb-ft) of torque, output 255 kW (347 hp): The new Audi SQ5 TDI (combined fuel consumption in l/100 km: 6.8 – 6.6*; combined CO2 emissions in g/km: 177 – 172*) once again has a powerful V6 engine under the hood, just like its successful predecessor of the first generation. An electric powered compressor ensures that maximum torque is available to the sporty SUV at just above idle; a mild hybrid system further enhances efficiency.The 3.0 V6 TDI engine in the new Audi SQ5 TDI combines instant and supreme power with high efficiency. 255 kW (347 hp) output at 3,950 rpm and 700 Nm (516.3 lb-ft) of torque at 2,500 to 3,100 rpm. The V6 diesel accelerates the sports SUV to highway speed in 5.1 seconds on its way to an electrically limited top speed of 250 km/h (155.3 mph). In the NEDC it consumes between 6.6 – 6.8 liters of diesel per 100 kilometers (35.6 – 34.6 US mpg), corresponding to 172 – 177 grams of CO2 per kilometer (276.8 – 284.9 g/mi). The SQ5 TDI is certified according to the Euro 6d-temp emission standard.Audi has systematically refined the drive concept from the full-size SQ7 TDI (combined fuel consumption in l/100 km: 7.6. – 7.2*; combined CO2 emissions in g/km: 199 – 189*) for the new SQ5 TDI. The 48-volt main electrical system includes an electric powered compressor (EPC) and a mild hybrid system. Energy is stored in a compact lithium-ion battery with an electrical capacity of 10 Ah located beneath the luggage compartment floor. An DC/DC converter connects the conventional 12-volt electrical system.

The Premium Platform Electric, or PPE for short, is a modular platform system designed for battery-electric drive. The battery module is the central element, in the Audi urbansphere concept it has a storage capacity of 120 kWh. Thanks to the 800-volt charging technology, energy for a 300-kilometre range can be charged in 10 minutes. PPE will massively accelerate Audi's transformation towards e-mobility via volume and diversity.
The electric all-wheel drive in the Q4 e-tron top models has an asynchronous motor (ASM) on the front wheels that can rev at up to 14,000 rpm. It is installed coaxially and has combined cooling with coolant and oil. The principal advantages of the ASM are its short-term overload capacity and the minimal drag losses when it is inactive – these are important because the front motor does not contribute to the drive in the majority of driving situations for reasons of efficiency.
