The production-ready 2015 Audi R8 e-tron is going to have a curb weight of 1,840 kg (4,056 lbs). This makes it substantially heavier than the conventional powered models as the entry-level R8 V10 weighs 1,555 kg (3,428 lbs) whereas the beefier R8 V10 Plus weighs 1,454 kg (3,205 lbs). The added weight has to do with all the extra hardware that you will find in any electric vehicle, in this case two electric motors, 92 kWh lithium-ion battery and a fixed-ratio gearbox.
Even though the car is quite heavy, the EV-related hardware hasn’t hampered the R8 e-tron’s performances that much as it will still be able to run the 0-62 mph (0-100 km/h) journey in only 3.9 seconds before hitting an electronically limited top speed of 130 mph (210 km/h). Audi has said they will optionally allow the customer to raise the limiter to 155 mph (250 km/h).
The two electric motors mentioned before provide the 2015 Audi R8 e-tron with a combined output of 462 HP (340 kW) and 679 lb-ft (920 Nm). As for the battery, it has enough energy to grant the electric supercar with a maximum range of 279 miles (450 km).
Audi has previously mentioned the R8 e-tron will be built to order later this year but the price tag is not known at this point.
