Audi has introduced a new plug-in hybrid powertrain to its Q5 range. The Q5 55 TFSI e will offer a 40km range and a top speed of 135km/h in electric-only mode.

The new drive concept combines Audi’s 2-liter TFSI four-cylinder, turbocharged gasoline engine, producing 252ps and 370Nm of torque with an electric motor. The permanently excited synchronous motor has a peak output of 141ps and peak torque of 350 Nm.

The e-motor and the separating clutch are integrated into the OEM’s seven-speed S tronic transmission, which uses ultra-technology to transfer the drive torque to the quattro drivetrain.

Overall, the hybrid powertrain system has a maximum output of 367ps and total torque of 500Nm from 1,250rpm. Acceleration from 0 to 100/km/h takes 5.3 seconds and the top speed is 238km/h. According to the standard for plug-in hybrid vehicles, combined fuel consumption according to the WLTP cycle is 113mpg, corresponding to 49 grams of CO₂ per km.

The SUV’s lithium-ion battery is located under the luggage compartment floor. It is made up of 104 prismatic cells and stores 14.1kWh of energy with a voltage of 381V. For optimal temperature control, its cooling loop is connected to both the coolant loop for the climate control system and the low-temperature cooling loop into which the electric motor and power electronics are also integrated.
