Electric Audi R8 e-tron supercar An R8 With 3,319.03 Lb-Ft Of Electric Torque [video]

It's official. The record has been set. Audi's 375-hp electric car — the Audi R8 e-tron — is the fastest "series production electric car" to lap the Nürburgring. Markus Winkelhock piloted the car around the 'Ring in 8:09.099.
Audi originally got cold feet over the car’s inadequate 134-mile range, although insiders say that up to 250 miles autonomy is now achievable due to improved power density of the lithium ion batteries.
So far just a handful of R8 e-tron prototypes exist, each worth near-enough one million euros. Performance was strong by sports car standards although modest in comparison to combustion-engined supercars such as the Ferrari 458 or Porsche 911 Turbo. Dispatching 0-60mph in 4.2 seconds, the car’s top speed was limited to 124mph, although more than 150mph was theoretically possible. Nothing to really trouble to Tesla Model S P85, then.
The Audi e-tron family is a series of electric and hybrid concept carsshown by Audi from 2009 onwards. In 2012 Audi produced a plug-in hybrid version, the Audi A3 Sportback e-tron, scheduled for retail sale in Europe for the second quarter of 2014, and in the U.S. in 2015
As this car is still in concept, much of its performance specifications are still uncertain. The car will have four electric motors, one per wheel. Together, these motors will produce 3,320 pound-feet (4,500 N·m) of torque. Top speed for the e-tron is limited to 200 kilometres per hour (124 mph), and will be able to travel 150 miles (240 km) on full charge.
In concept form, the e-tron also is equipped with conceptual technology: technology that communicates with other cars, road signs, etc
The first e-tron concept car was shown at the 2009 Frankfurt Motor Show. A two-seater, similar in appearance to the Audi R8 but slightly smaller, is powered by four UQM Technologies motors,providing four-wheel drive. Together, these produce 313 PS (230 kW; 309 hp) and 4,500 N·m (Template:Convert/lb-ft) of torque, resulting in an acceleration of 0 to 100 km/h (62 mph) in 4.8 seconds.
A 470 kg (1,036 lb) 42.4 kWh lithium-ion battery is located in front of the rear axle and provides a range of approximately 248 km (154 mi) with a full charge taking 6–8 hours from a normal household socket. The ceramic brake discs can also provide regenerative braking energy. A limited production model based on this car, called the R8 e-tron is reported to be under development.
In November 2012 it was announced to shelf the development project for undefined duration
