Total output is rated at 355 horsepower and 414 pound-feet of torque

Audi has finally released technical information for the E-Tron electric SUV, and there are plenty of juicy bits to parse through. Chief among these details is the e-Tron’s power output, which is rated at 355 horsepower and 414 pound-feet of torque, all of which comes from a pair of electric motors. The power output of the e-Tron is just one of many new details Audi released about the electric SUV. Apparently, it also has short-term boost capability, a feature that unlocks the e-Tron’s full power figures — 402 horsepower and 490 pound-feet of torque — albeit for just eight seconds at a time.

The power numbers of the Audi e-Tron aren’t the only figures Audi released. As a result of the SUV’s ability to produce 355 horsepower and 414 pound-feet of torque, the e-Tron is also capable of sprinting from 0 to 62 mph in under six seconds before hitting an electronically limited top speed of 124 mph. Since the model, at its heart, is an electric car, range is also of paramount importance for those who are looking into the e-Tron as a potential personal ride. On that end, the Audi EV makes use of a 95 kWh battery pack that can store enough juice to deliver 248.5 miles between charges. The range is based on the Worldwide Harmonized Light Vehicle Test Procedure (WLTIP), a laboratory test used to measure fuel consumption and CO2 emissions from passenger cars under conditions defined by EU law. This new test now takes precedence in terms of legitimacy and importance over the outgoing NEDC test cycle.

Speaking of the e-Tron’s range, the electric vehicle has an ace up its sleeve in the form of a recuperation system that can extend overall range by as much as 30 percent. According to Audi, the e-Tron comes with three different recuperation modes that can recharge the battery pack as often as possible. It has brake energy recuperation, automatic coasting recuperation, and manual coasting recuperation. When used properly, the e-Tron can recuperate one kilometer of range (0.62 miles) for every kilometer (0.62 miles) the SUV is driven downhill. Even more remarkable is Audi’s claim that “no series production model has achieved such a value up to now.”

Given what we know and expect about the e-Tron, it’s clear from these technical numbers that the electric SUV has more to offer than what we expected. It’s made the model more appealing ahead of its debut, which is likely to happen at the 2018 Frankfurt Motor Show next month.

And if you want to get even more excited about Audi’s e-Tron lineup, rest assured that the fun’s just getting started. The automaker’s family of EVs is expected to grow in the future to include the e-Tron Sportback, e-Tron GT sedan, and perhaps even an electric supercar that may or may not appear at the Pebble Beach Concours d’Elegance.

Highly efficient: up to 30 percent more range thanks to energy recuperation
World premiere in electric cars: the electrohydraulically integrated brake control system
Strong performance: up to 300 kW and from 0 to 100 km/h (62.1 mph) in less than six seconds
INGOLSTADT, Germany/COLORADO SPRINGS, Colo., August 8, 2018 – The Audi e-tron prototype combines enormous power and high efficiency. With a system output of up to 300 kW, the full-size SUV with a fully electric drive accelerates from zero to 100 km/h (62.1 mph) in less than six seconds. In the WLTP test cycle, it covers more than 400 kilometers (248.5 mi) on one battery charge. One important factor for the long range is the most innovative recuperation concept among the competitors. The electric SUV proved this with an impressive performance at Pikes Peak.

The scenario: Each kilometer downhill brings around an additional kilometer in range
At 4,302 meters (14,115 ft), Pikes Peak looms high in the southern Rocky Mountains. Where Walter Röhrl won the world’s most famous hill climb in the Audi Sport quattro S1 back in 1987, it is the Audi e-tron prototype that is now causing a sensation with its recuperation system that is variable and thus the most efficient among all the competitors. On its 31 kilometer (19 mi) downhill drive, the electric SUV feeds so much energy back to the battery that it can cover approximately the same distance again. The difference in altitude of about 1,900 meters (6,233.6 ft) provides the necessary conditions for this. The Audi e-tron prototype recuperates energy with up to 300 Nm of torque (221.3 lb-ft) and 220 kW of electric power – more than 70 percent of its operating energy input. No series production model has achieved such a value up to now.

The recuperation concept: from freewheeling to a one-pedal feeling
The recuperation system contributes to up to 30 percent of the electric SUV’s range. It involves both the two electric motors and the electrohydraulically integrated brake control system. For the first time, three different recuperation modes are combined: manual coasting recuperation using the shift paddles, automatic coasting recuperation via the predictive efficiency assist, and brake recuperation with smooth transition between electric and hydraulic deceleration. Up to 0.3 g, the Audi e-tron prototype recuperates energy solely via the electric motors, without using the conventional brake – that covers over 90 percent of all decelerations. As a result, energy is fed back to the battery in practically all normal braking maneuvers.

The driver can select the degree of coasting recuperation in three stages using the steering wheel paddles. At the lowest stage, the vehicle coasts with no additional drag torque when the driver releases the accelerator pedal. At the highest stage, the electric SUV reduces the speed noticeably – the driver can slow down and accelerate using only the accelerator pedal. This creates the one-pedal feeling. There is no need to use the brake pedal in this deceleration scenario.

The wheel brakes are involved only when the driver decelerates by more than 0.3 g using the brake pedal. They respond extremely quickly, thanks to a new electrohydraulic actuation concept. Audi is the first manufacturer worldwide to use this concept in a series production vehicle with electric drive. A hydraulic piston in the compact brake module generates additional pressure and thus additional brake force for the recuperation torque. When automated emergency braking is performed, there are only 150 milliseconds between the initiation of the deceleration and the presence of maximum brake pressure between the pads and disks. Thanks to this rapid pressure buildup, the braking distance is shortened by up to 20 percent compared with a conventional brake system.

Depending on the driving situation, the electrohydraulically integrated brake control system decides – electrically on each individual axle – whether the Audi e-tron prototype will decelerate using the electric motor, the wheel brake, or a combination of the two. The brake pedal is decoupled from the hydraulic system. The transition from the engine brake to the pure friction brake is smooth, and the driver does not notice it. This system allows the electric SUV to exploit its maximum recuperation potential in a targeted manner with support from the standard efficiency assist. The system uses radar sensors, camera images, navigation data and Car-to-X information to detect the traffic environment and the route. The driver is shown corresponding information in the Audi virtual cockpit as soon as it would be sensible to take the foot off the accelerator pedal. By interacting with the optional adaptive cruise assist, the efficiency assist can also decelerate and accelerate the electric SUV predictively.

The asynchronous motors: strong performance
What is fascinating about the SUV with electric drive is not just its efficiency but also its performance. Its two electric motors have an output of 265 kW and develop 561 Nm
(413.8 lb-ft) of torque. They can deliver this peak performance for up to 60 seconds. This way, they allow the vehicle to accelerate from a standstill to the electronically limited top speed of 200 km/h (124.3 mph) several times consecutively without output losses. The maximum drive torque is present within fractions of a second and provides enormous torque. By shifting from drive range D to S and fully depressing the right-hand pedal, the driver can activate boost mode. It is available for eight seconds. Here, the drive produces 300 kW of system output and 664 Nm (489.7 lb-ft) of torque. The Audi e-tron prototype sprints from 0 to 100 km/h (62.1 mph) in
less than six seconds.
