The Audi E-Tron GT will have a 90-kWh battery and is said to return 400 km (248.5 miles). The Model S, with only a 75-kWh pack, is rated for 416.8 km (259 miles) using the EPA test.
Audi E-Tron and Tesla Model S share a number of features: four doors, dual motors for all-wheel-drive, and a sporty level of performance.
The Audi E-Tron GT is said to be able to charge to 80% from empty in 20 minutes. On positive note, though: charging networks for non-Tesla vehicles should be much better developed in two years time given the effort being put into the Ionity charging network in Europe and Electricity System in the U.S.
For home charging, the Audi and Tesla are quite close, but with an interesting difference. The Tesla comes with an 11.5 kW onboard AC charger which would be plugged into a Tesla Wall Connector. The Audi features 11 kW wireless charging which would be extremely convenient: just park over the charging pad and the charging just happens.
About performance. The Audi E-Tron GT is said to scoot from 0-to-60 miles per hour in 3.5 seconds and tops out at 149 mph (240 km/h). This particular Tesla, can manage to accelerate to 60 mph in 4.2 seconds and offers a 140-mph top speed.
