The minds of the leading car manufacturers excites the idea of developing a hardy and fast supercar on electricity. The 2018-2019 Audi a couple of years ago, conceived to equip motors model, presenting an alternative to traditional internal combustion engines R8 V8 and the V10 . While the novelty of Ingolstadt in mass production and is not going to pass numerous tests. Misfire here should not be allowed, since we are talking about high-tech supercar.
One problem with electric cars is the limited cruising range, depending on the quality and capacity of traction batteries. Reduce the “voracity” of electric motors is possible by reducing the weight of the vehicle. Body 2018-2019 Audi R8 e-tron weighs 199 kilograms, which is 23 kg less than the R8 Coupe. As the body of the material used in aluminum and carbon fiber. Conventional suspension springs would be too mediocre elements of a high-performance supercar, so the German automobile latest GRP installed.
Externally, the 2018-2019 Audi R8 e-tron is similar to the modification of gasoline, but the aerodynamics in the electric vehicle will be better. The absence of the engine and exhaust system allowed to make a flat bottom and give up some of the vents. The coefficient of drag of environmentally friendly supercar is 0.27. The battery is located between the axles, which reduces the vehicle center of gravity velocity for increasing stability.
The two electric motors on the rear axle, powered by batteries with 48.6 kWh, develop power 280 kW (380 hp) and produce enormous torque of 820 Nm. From zero to hundred kilometers per hour the R8 e-tron accelerates in 4.2 seconds and reaches a top speed of 200 km / h. Distance running, the manufacturer, is 215 kilometers, after which the car will have to spend near the outlet of about 12 hours.
The so-called fast charging (DC) allows charging the battery per hour. For comparison: Mercedes SLS AMG Coupe Electric Drive charging even longer, but is superior to 2018-2019 Audi. Electric cars help save energy with special low rolling resistance tire dimension 225 / 35R19 front and 275/3519 rear.
Silent electric vehicles at the same time became the advantages and disadvantages. To protect pedestrians from cars creeping quietly without the internal combustion engine, the manufacturer is obliged to put the device, creating a familiar car sounds. In the 2018-2019 Audi R8 e-throne has a so-called generator “synthetic noise” and it works to a speed of 60 km / h, after which it is reasonable efforts wheel noise.
Some successes electric coupe R8 has already managed to achieve. The summer of supercar running German driver Markus Winkelhock crossed the North Loop of the Nürburgring in 8: 09,099, setting a record time of passage of the famous electric car track.
Inside, 2018-2019 Audi R8 e-tron is to provide a rear-view mirror, which is a 6.8-inch AMOLED display with active-matrix organic light emitting diode, working together with a broad overview of the camera. Sport car seats have a frame made of carbon fiber and weigh less than 20 kilograms each.
