2013 Audi R8 e-tron

R8 e-tron

The Audi R8 e-tron how emotional and dynamic electric can be. Its two electric motors, supplied energy by a large 48.6 kWh develop 280 kW (380 hp) along 820 Nm (604.80 lb-ft) of torque. accelerate the high-performance sports car 0 to 100 km/h (62.14 mph) in 4.2 and to a governed top speed of 200 km/h mph). The battery charge is for an operating range of 215 kilometers miles).

Through the R8 e-tron, has acquired extensive expertise will benefit its electrified models.

The Audi R8 e-tron in at 1,780 kilograms (3,924.23 Its body structure, including the sections, weighs just 199 (438.72 lb), 23 kilograms lb) less than that of the R8 which already sets the bar high with its aluminum-based ASF (Audi Space Frame). Audi presents a new stage in the of its ultra lightweight construction – a Multimaterial Space Frame, in large parts made of polymer (CFRP) supplement the frame.

The CFRP components 23 percent and the metal parts 75 of the bodyshell weight; miscellaneous make up the remainder. The forward of the R8 e-tron is a classic aluminum The dominant material in the occupant is CFRP, with the tail end a blend of both materials.

The trunk insert of CRFP corrugated crash structures mean the rear module can five times as much as an aluminum lattice structure. For the and rear bulkhead, a new sandwich reduces the weight by 11.5 (25.35 lb).

Every part of the outer skin, is made almost entirely of is tailored specifically to its position and In certain zones of the front for instance, there are seven of carbon fiber matting one on top of the For the inner shells of the rear sections, on the other hand, two incorporating nonwoven material are

The lithium-ion battery, too, is a of the development expertise of Audi – it was and built in-house. Bolted to the at 40 points, it functions as a supporting that more than the rigidity of the Multimaterial Space The battery incorporates 530 prismatic cells. Taking the shape of a T, the is 235 centimeters (92.52 in) long, 135 (53.15 in) wide and, unit included, 71 centimeters in) high.

Around the tunnel are two floors with cell one above the other; at the rear end are four floors.

Plates 12 (0.47 in) thick made high-strength aluminum alloys the floors, while forming the supporting structure. The coolant through narrow channels cut these, with a total of several hundred meters. A distributor maintains a precisely smooth flow serving all equally.

The battery management is housed together with the switches and power fuses in the box, which is located on the battery. The main tasks of the management system involve the battery system’s safety if need be, taking appropriate to prevent danger. It also the charge status and performance of the HV and transmits the readings to the electric drive controllers. To do that, the management system, for example, a battery-internal network of cell to gage cell voltages and

If the battery’s charge level towards the threshold of 15 percent SOC of charge), the controller correspondingly the amount of electrical power can be taken from the battery. In the functioning and safety of the high-voltage system are permanently monitored; in the of an accident, the battery is deactivated.

There are two options available for the battery: A full charge 230-volt alternating current the domestic mains takes twelve hours. Charging direct current cuts the required to less than one depending on the connected load. The can control and monitor a wide of functions and information remotely by app, including the charge the interior heating and the range

This is a customized service Audi connect, which is used in a very similar in models such as the A3 Sportback

The battery is also recharged on the road by means of energy during retardation phases. The chooses the degree of energy in three stages (plus at paddles on the steering wheel. The is especially high when because up to about 0.3 g the electric normally handle retardation on own.

Beyond that the brake system then comes into play, and the motors can recover up to 0.45 g. The developed electric individual-wheel control (eASR) maintains stability when braking, and compelling traction when

The two electric motors on the rear of the Audi R8 e-tron enable torque vectoring, the targeted and acceleration of individual wheels for torque distribution during cornering. Thanks to the separate of the electric motors and their behavior, this function is variable and fast; in theory the sports car can brake one wheel powering the other with torque.

With a total of 280 kW and 820 Nm lb-ft) available virtually off, the electric motors the Audi R8 e-tron impressive They catapult it from 0 to 100 (62.14 mph) in 4.2 seconds, and top is limited to 200 km/h (124.27 In the test-bench cycle, one battery is sufficient for driving over 215 (133.59 miles).

The electric achieve over 95 percent over a wide range; they could rev up to 12,500 which would make capable of a speed of more 250 km/h (155.34 mph). as permanently excited synchronous they deliver a high and torque density and can also run on a small amount of electricity. The temperature is controlled by a water and the air additionally cooled by an air flow.

The single-stage planetary gears are into the cooling circuit.

electric motor is supplied by power electronics, which are temperature-controlled. The pulse inverters convert the battery’s direct-current into alternating-current voltage the benchmark for compact, lightweight The driveline’s control concept has redundancy and satisfies the highest safety standards – the controllers of the electronics communicate with other and with the drive

The chassis of the Audi R8 e-tron, features new solutions. The coil are made from glass-fiber-reinforced (GFRP) and weigh only 1.2 and 1.3 (2.65 and 2.87 lb) respectively, 40 percent less than springs. The rear wheel are of forged titanium, saving 0.6 (1.32 lb) of weight.

For the anti-roll bar at the wound layers of CFRP the tube, and the shanks are made aluminum – the component weighs 2.5 kilograms (5.51 lb), a of 35 percent.

The Audi R8 e-tron is with size 225/35 and tires with optimized resistance. From about 50 (31.07 mph), adjustable close the apertures in the 19-inch by centrifugal force; at low speeds open again. The active wheels trim about off the cD value.

The wheel brakes at the are electromechanical screw brakes. actuated and controlled ball drives (“by wire”) the pads against the disks lightning speed. There is a brake system on the front with two vacuum pumps the required partial vacuum.

the disks are made from fiber ceramic.

With a distribution of 42:58, the R8 e-tron is with just the right for sporty handling. The battery is between the axles, with a low position that lowers the center of gravity. Racing Markus Winkelhock established two new for electric-drive production vehicles the R8 e-tron on the Nьrburgring North He clocked up 8:09.099 minutes for the single lap and 16:56.966 minutes for two laps. For the single lap he drove on tires approved for a top speed of 250 (155.34 mph), and used tires with a 200 km/h mph) speed limit for the lap.

The Audi R8 e-tron looks to the Audi R8 with gasoline but the two vehicle body versions only nine common The drag coefficient of the electrically high-performance sports car is cD = 0.27. The of a combustion engine, transmission and system permit a smooth At its rear end a long, relatively raked diffuser deflects the air in a way harmonizes with the air flow the tail end.

The spoiler is slightly higher than on the R8, and is no spoiler.

The electrically powered sports car does not have an oil nor does it need intake Its side air inlets at the front as as the sideblades are sealed. Cooling air is admitted through the lower of the Singleframe grille.

It is required for the management. It flows through the structure in a duct and emerges through an opening in the front

In the shape of the multi-source heat Audi has realized a high-performance management solution for the R8 e-tron will be of great benefit to production models. The highly system keeps all important components – the battery, the electric the transmissions and the power electronics – at the temperature level. The heat it draws off is used to regulate the climate.

The efficient use of electrical energy the range by up to 20 percent.

The heat is based on the principle of the classic circuit. As a new component, it incorporates (elements which handle exchange between two fluids), the condenser/evaporator, electrically operated valves and an additional heater in the air conditioning unit. A heat developed by Audi manages how the interact; depending on the situation, it the best from 43 variants. The pump in the R8 e-tron, which operates independently, heats up the faster than a conventional or air conditioning system.

With an output of 1 kW, it can supply up to 3 kW of heating

When the system operates as an heat pump, it draws from the ambient air. is transferred to the refrigerant circuit via the condenser, which in this operates as an evaporator. At low outside the heat pump makes use of the heat from the electric and high-voltage battery via special the chillers, which simultaneously the assemblies.

The heater controller heats up the interior by transferring the energy stored in the refrigerant to the air drawn in. An electric PTC auxiliary only cuts in if maximum speed is required.

The interior of the R8 e-tron features elegant surfaces, soft leather and The sport bucket seats a CFRP chassis; each of weighs only 17.6 (38.80 lb). In the instrument LED strips indicate the coolant and battery charge level.

The powermeter presents the level of output and energy recovery on a from 0 to 100 percent. There is a color monitor for the driver system; together with the MMI it shows all important facts electric driving. These power consumption (in kW/h per 100 the chosen energy recovery the amount of energy recovered and an graphic of the energy flow.

In addition, the range is displayed in the navigation system’s map view.
