As the trailblazer for a new range of plug-in models from Audi, the Q5 55 TFSI e is about to make a suitably progressive statement by combining the economic and environmental benefits of electrified driving with the demand-led efficiency of quattro with ultra technology for the first time.
The new drive concept combines a 2.0 TFSI four-cylinder, turbocharged petrol engine producing 249bhp and 370Nm of torque with an electric motor. The permanently excited synchronous motor has a peak output of 105kW and peak torque of 350Nm.
It and the separating clutch are integrated into the seven-speed S tronic, which uses ultra technology to transfer the drive torque to the quattro drivetrain.
Overall, the hybrid SUV impresses with a system output of 362bhp and total torque of 500Nm just above idle, namely from 1,250rpm. Acceleration from 0-100km/h takes 5.3 seconds; 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 49g of CO2/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.
The climate control system uses a highly efficient heat pump that pools the waste heat from the high-voltage components. With 1kW of electrical energy, it can generate up to 3kW of thermal heating output. That makes the car more efficient and also provides a more comfortable climate for the occupants.
