Audi presents PHEV concept with two electric motors and wireless charging

Audi is presenting a new concept PHEV at this week’s Beijing International Automobile Exhibition that showcases a number of cutting-edge technologies, including wireless charging.

The Audi TT offroad concept is based on the modular transverse matrix (MQB), the Volkswagen Group’s common engine-mounting core, which allows a model to be produced with different drivetrains (legacy, hybrid or electric) on the same line.

The TT concept features a plug-in hybrid drive with total power of 300 kW (408 hp) and 650 N·m (479 lb‑ft) of system torque. It does 0-100 km/h (62 mph) in 5.2 seconds, and has an electronically governed top speed of 155 mph. Fuel economy is estimated at 123 mpg, and electric range at about 31 miles.

The combustion engine is a transverse-mounted turbocharged 2.0 TFSI unit producing 215 kW (292 hp) and 380 N·m (280 lb‑ft) of torque. A separating clutch links the ICE to a slim 40 kW electric motor that’s integrated into the six-speed transmission. Mounted on the rear axle is an independent 85 kW electric motor. The liquid-cooled, 12 kWh lithium-ion battery pack has eight modules.

The show car is designed for use with Audi Wireless Charging technology, which consists of a plate with a coil and an inverter on the parking spot and a second coil integrated into the vehicle. Charging takes place at 3.3 kW AC. Audi says its charging technology is more than 90% efficient, and is not affected by rain, snow or ice.

The TT concept offers three driving modes and a couple of driver assistance systems. The intersection assistant aims to help avoid side-impact collisions by using radar sensors and a wide-angle video camera to detect vehicles approaching from the side and display a warning. Online traffic light information is designed to connect the vehicle with a city’s central traffic computer, and show the driver what speed to drive in order to reach the next traffic light while it is green.                                 

“The Audi TT offroad concept provides a glimpse of how we might imagine a new model in the future TT family,” said Board Member Ulrich Hackenberg. “Its plug‑in hybrid drive with the option of inductive charging is a major step toward the mobility of the future. We chose to present the Audi TT offroad concept in China, our second domestic market, because it represents the urban mobility of tomorrow: It is sustainable, dynamic, intelligent and connected.”
