Just about a year after the first e-tron all-electric SUV was introduced to the world, Audi has unveiled at the 2019 Geneva International Motor Show a concept for the next product in its all-electric lineup—the Q4 e-tron. Combining the two fastest-growing trends in the automotive sector to create a battery-powered SUV, the Q4 e-tron offers a WLTP-measured range of 450 km (280 mi), a zero to 100 km/h (62 mph) time of 6.3 s, and an impressive charging time.
Audi says that the follow-up to the original e-tron is just the beginning of a huge product offensive on the EV market. The Q4 e-tron sits on the Volkswagen Group’s now-familiar MEB modular electrification platform, for which two electric motors (each driving one of the axles) combining for 225 kW of power work together with an 82-kW·h battery. The electric motor in the rear has 150 kW and 310 N·m (229 lb·ft) of torque, while up front there is 75 kW and 150 N·m (111 lb·ft) on tap. The battery is charged with a maximum of 125 kW, enabling a 30-min charge to provide 80% of the total capacity.
Audi says that, in the majority of cases, the rear electric motor will be used in the Q4 e-tron, to achieve the highest level of efficiency. This permanently excited synchronous motor is then joined in providing power by the asynchronous motor to redistribute the torque to the front wheels.
Keen to retain the combination of practicality and dynamic attributes that feature in all of Audi’s other Q cars, the location of the 510-kg (1125-lb) battery system was given careful consideration. Housing the pack in a flat block beneath the passenger compartment, it enables the e-tron to achieve a similar center of gravity to a mid-size sedan.
That 450-km range might be testament to the new batteries onboard the Q4 e-tron, but it’s helped by an aerodynamic body (with a Cd figure of 0.28) as well as an advanced energy-recuperation system. Audi also points to the thermal management of the drive and battery, including a CO2 heat pump.
The digital cockpit has become a popular addition to a number of Audi models in recent years, and, in the Q4 e-tron, augmented reality has been added into the mix on the head-up display unit. The concept boasts a 12.3-in touchscreen from where infotainment, connectivity, and other vehicle functions can be controlled.
Like many other manufacturers in Geneva, Audi made a major commitment to electric vehicles. By 2025, the company will offer no fewer than 12 models with all-electric drive in its major global markets. These vehicles will account for around one-third of the company’s total sales. In addition to the e-tron, Q4 e-tron, and the forthcoming e-tron Sportback (due to make its debut in 2019), Audi promises a range of models with classic body layouts such as Avant and Sportback. This EV line-up will cover every relevant market segment from the compact class to the luxury class, says Audi.
