The all-electric e-tron concept by Audi made its debut at the Frankfurt Motor Show in 2009. This amazing new technology surprised the car lovers by being displayed at Los Angeles in a unique paint scheme. The technology then made its way to the production factory with the nameplate, R4. E-tron is counted among the high-performance electric sports vehicle engines created in the same vein as R8.
This system is technically not an electric version of R8 supercar by Audi. E-tron concepts put emphasis on performance and at the same time, it shares a considerable amount of design language too. Audi e-tron has independent electric motors at four corners. These features give this new concept a touch of quattro all-wheel technology. Combined output of the two is 313 horsepower and 3,319 lb-ft torque. Its power accelerates e-tron from 0 to 62 in just 4.8 seconds. The rush is accomplished in 4.1 seconds from 37-75 mph.
A lithium-ion battery is used for the e-trons. It is located behind the passenger compartment for optimal weight distribution. According to Audi, e-tron carries enough food for a 154 mile optimal range. Audi uses LED lights and several other power saving features to ensure maximum range.
Audi e-tron is very light in weight and it weighs only 3,527 pounds. It has a huge battery pack of 1,036 pounds. Its weight is low mainly due to its Audi Space Frame designed aluminum structure. The ‘add on’ parts like, hoods, roof, doors, and fenders are made of fiber-reinforced plastic that weight can be minimalist.
`The car featured in the show included simplistic controls and revised MMI scroll pad with its touch sensitive surface on steering wheel. There is a smart phone integration setup. Smart phones can be inserted into a slot made for using the phone’s built-in audio and video processes. Most automakers are concerned about budget EVs for driving on the city roads. Vehicles with Audi E-Tron are highly priced mainly due to the high price of lithium-ion batteries.
After the bang in the Frankfurt show in 2009, Audi unveiled the second lot of electric sports car concept in 2010. This system is also called Audi E-Tron. In this E-Tron, a pair of asynchronous electric motors generates power of 201bhp. Like the very original E-Tron, a huge torque figure of 1955lb ft, is also created by this Audi system.
The first Audi E-Tron’s torque is 3,319lb ft measured at the wheels instead of output shaft. That means, in conventional measurement, this can generate something nearer to 250lb ft. The 2010 E-Tron’s actual torque is a bit lower.
According to Audi, the new E-Tron hits 62mph in 5.9 seconds. It tops out at a limited 124mph. The drain on the batteries above this speed gets increased disproportionately. The light weight of 1,350kg proves that the technology is astonishingly svelte for an electric car. It is still a concept. According to Audi, E-Tron has a range of 155mph. But, it is necessary to be gentle on the throttle for achieving that. Audi has utilized its E-Tron system in models like, A1, Spyder, R18, etc. and now probably on R8.
