Audi’s Q4 e-tron concept, first displayed at the 2019 Geneva Motor Show, is a compact electric SUV—a bit smaller than the original e-tron mid-size crossover SUV, which has been on sale since May 2019. Now the company has presented two more Q4 variants: the Q4 Sportback e-tron and SUV Coupé. Audi says the newly revealed cars are very similar to the versions that will go into production in 2021.
The two Q4 models are built on the Volkswagen Group’s modular electrification platform (MEB). They have almost identical dimensions, and share the same drive technology. Both versions do zero to 100 km/h (62 mph) in 6.3 seconds, and have a software-restricted top speed of 180 km/h (112 mph).
The 82 kWh battery pack weighs 510 kg (1,124 lbs), and takes up almost the entire space in the underbody area between the axles. Range is estimated at 450 km (280 miles, by the WLTP testing standard) for AWD versions, and 500 km (311 miles) for rear-wheel drive versions.
The thermal management system for the drive and battery pack features a CO2 heat pump.
The rear electric motor has an output of 150 kW and torque of 310 newton-meters (229 lb-ft); the front motor delivers 75 kW and 150 N-m (111 lb-ft). Total system output is 225 kW.
There is no mechanical connection between the axles— torque is electronically distributed to achieve optimum traction in all weather conditions and on any surface. For reasons of efficiency, most of the torque is usually going to the rear permanently excited synchronous motor. If more power or more traction is needed, the electric all-wheel drive redistributes torque to the front asynchronous motor as required.
The Audi “virtual cockpit” features a screen with the most important display elements—speed, charge level and navigation—behind the steering wheel, plus a 12.3-inch touchscreen above the center console for infotainment and other vehicle functions. There’s also a large-format head-up display with an augmented reality function.
Audi says there will also be lower-powered versions, with a single motor and a smaller battery pack. The Q4 line is expected to start at under 40,000 euros ($45,000).
By 2025, Audi plans to offer over 20 pure EVs in its most important global markets, and achieve roughly 40 percent of its sales with electrified models.
