The All New Audi R8 E-Tron Concept Car

With the Frankfurt motor show's press days underway, Audi revealed a technical study that examines what its R8 sports car might be like if powered by four powerful electric motors. The answer is E-Tron. The four motors fitted under the hood produce a modest 313 horse power but an astronomical 3,319 pound-feet of torque. Isn't it amazing!
The total torque produced does not come at once. Such a quantity of twisting force usually found in the M47 Patton tank would turn all the tires into rubber vapor at the first throttle. The E-Tron is equipped with an electronic version of torque-vectoring system that is found in some of the Audi cars which are already on the road. This electronic version distributes the required torque to each wheel as needed to maximize traction the cornering ability. As Audi says it takes 4.8 seconds to get to 100 Km/h (62 Mph) from 0. This may not be termed as spectacular when compared with other super-cars. But once the rolling sets to go, the plot quickens - 37 Mph to 75 Mph in just 4.1 seconds, the extra torque stepping into defeat the mountain forces of friction and the resistance by wind.
Top speed has been clocked for 127 miles per hour. This may not be of much service when it comes to long trips, considering its range of 154 miles. The total energy content of the liquid-cooled batteries is roughly 53 kilowatt hours, with a usable portion restricted to 42.4 kilowatt hour, to increase the life of battery service. The weight distribution was managed properly and is very close to that of a gasoline powered R8. The heavy battery pack has been mounted behind the passenger cabin to optimize the center of gravity and axle load distribution, giving the car a front/rear weight loading of 42/58. A specialized thermal management system has been installed which controls the temperature of the driving system, power electronics, battery and the interior climatic control. A heat pump is also installed to warm up the interior in case of unavailability of waste heat from the electrical system.
The Audi E-Tron concept's interior takes advantage of the lack of a traditional drive train encroaching on space; designers created a slim center tunnel and console with a flush gear selector
The Audi R8 E-Tron also communicates with its surroundings. Yes, that's right. E-Tron showcases of something Audi calls as "Car-to-x-communication". It's a prototype for an information-processing system that networks the E-Tron to other cars and its surroundings by way of transmitting devices. Such a system can help reduce accidents, minimize roadway congestion and open up new convenience functions like finding a parking space in a crowded parking lot. Like most concept cars, Audi has no plans to build the E-Tron as on a whole, say a competitor to the Tesla Roadster, though expect to see some of the technology and design cues show up in other vehicles. The parking system would be the hottest feature.
