Audi is investigating ways of adding new models to the TT range, and the first exploration in this vein is the Audi TT offroad concept, unveiled today at the Beijing Auto Show in China.
Audi says the concept combines the ‘sporty genes of the TT with the strengths of a compact SUV’.
The Audi TT offroad concept is a plug-in hybrid, featuring power from both a 2.0-litre TFSI petrol engine developing 292 hp and 380 Nm of torque, plus a pair of electric motors.
One, producing 40 kW and 220 Nm, is integrated into the six-speed dual-clutch transmission, while another is mounted on the rear axle, capable of delivering 85 kW and 270 Nm.
Combined, this gives the TT offroad concept 408 hp and 650 Nm of torque to play with, and this leads to a 5.2 second 0-62 mph time and a 155 mph electronically-limited top speed.
However, the real benefit is in efficiency, with the concept achieving 149 mpg while emitting just 45 g/km of CO2.
It can even drive for up to 31 miles on electric power alone fed from a 12 kWh liquid-cooled lithium-ion battery mounted just ahead of the rear axle.
Recharging the battery can be achieved either via a wall box or Audi’s Wireless Charging technology.
This requires a special charging plate embedded into a parking spot with an alternating magnetic field that induces a 3.3 kW current in a coil mounted on the underside of the vehicle.
Audi claims the system is 90% efficient, isn’t affected by rain, snow or ice, and can recharge the vehicle in the same time as a cabled charge.
Three driving modes are available: EV mode drives the vehicle using the rear electric motor at speeds of up to 80.8 mph.
Hybrid mode allows both electric motors and the petrol engine to work together, although the front-mounted electric motor works mostly as a generator, using the petrol engine’s power to recharge the battery and extended the range (to a potential total range of 547 miles).
In Sport mode, the full combined output of the system is available, with the powerful rear motor providing additional acceleration to help the petrol unit as required.
The system can also switch in electric motors to provide four-wheel-drive when additional traction is needed in slippery conditions.
