The E-Tron GT will have two different motor setups available. Both the base model and the RS feature a 235-hp front motor. In the base model, the rear motor is a 429-hp unit that, combined with the front motor, produces 469 hp until the car is put into “overboost” launch control mode, which increases combined output briefly to 522 hp for 2.5 seconds. The base model’s motors crank out a combined 464 lb.-ft. of torque (472 lb.-ft in overboost), and the car has a top speed of 152 mph. The RS model has a more powerful 450-hp rear motor, which, combined with the front motor, puts out 590 hp (637 hp in overboost). The top torque output for the RS is 612 lb.-ft., and its top speed is 155 mph.
Unlike some of the gasoline-powered Audi cars currently on the road, the electric models don’t make much noise. So Audi’s audio engineers created a unique acceleration sound, to enhance the driving experience and to alert pedestrians to the vehicle’s approach. In a video published on Audi’s media site last fall, the company explains that different sounds will be available for the various driving modes. The sound bites available on the internet thus far depict a space-age sound that will put the “Tron” in E-Tron.
Most electric cars available right now rely on a direct drive without gear ratios, but the E-Tron GT features a two-speed transmission with one gear for acceleration, and the other for highway cruising. The car features an electronically controlled air suspension that can adjust its firmness for different driving demands, and which allows the ride height to be raised nearly an inch up or down from its center position. Four-wheel steering—which turns the rear wheels a few degrees in the opposite direction from the front wheels at low speeds to increase maneuverability, and turns them the same direction as the front wheels at higher speeds to aid stability—is standard on the RS version, and optional on the base model.
The two E-Tron GT models have the same 93-kWh battery pack, which sits within an aluminum frame beneath the cabin floor. Audi says the car’s 800-volt charging system allows the battery to be charged from 5 percent capacity to 80 percent capacity in 22 and a half minutes using DC fast charging that can be found in public places. In the absence of EPA-certified numbers, Audi estimates that the E-Tron GT has 238 miles of range in base trim and 231 miles of range in RS trim. That is a few miles more than the EPA’s range estimate for the Taycan 4S, but significantly less than the 387-mile EPA range estimate for the top-performing Tesla Model S.
