Audi has revealed more technical details of its upcoming electric SUV, which will be revealed later this year
9 August 2018

Audi has revealed that its upcoming e-tron electric SUV will get a maximum power output of 402bhp, with torque of 490lb ft, which will enable the car to reach 62mph in less than six seconds. Top speed is electronically limited to 124mph (200kph).

Under normal driving conditions, the combined power of the car's two motors is 350bhp, with torque of 414lb ft of torque, although a boost mode unlocks the full 402bhp for up to eight seconds.

The car, which is due to be fully revealed later this year at the postponed Audi Summit, will be powered by a dual-motor powertrain using a 95kWh lithium ion battery and capable of 150kW DC fast charging. The latter is claimed as a world first and is 30kW more rapid than Tesla's Supercharger network. It can charge the car in just 30 minutes.

Also confirmed is the use of alternating current AC chargers that can top up the battery by recovering energy on the move. As standard, the car will feature 11kW chargers for this, although 22kW chargers will be available as an option to enhance the recovery rate.

Audi also revealed details about the car's regenerative braking system; it can recuperate up to 30% of the car's total range, while the car brakes using an electrohydraulic system for quicker responses, thanks to the additional pressure of a hydraulic piston. The system, Audi claims, can reduce braking distance by up to 20%, as there is little delay in getting the brakes applied with full pressure.

Our Verdict

Audi Q5

Audi replaces the best-selling Q5 SUV with a model very much on the same theme, but does more sophistication make it a more compelling option than the BMW X3, Mercedes-Benz GLC or the Volvo XC60?

Home charging details have also been disclosed; Audi says that the e-tron can charge fully in 8.5 hours when connected to a 400V three-phase outlet. It's yet to reveal times for when the car is attached to a regular 230V household plug.

The extra technical info for the e-tron was shown to the press at a Siemens heavy-duty electrical engineering test centre in Berlin, Germany, where the car was subjected to a symbolic 500kV test to ‘spark the car into life'.

The brand previously showed interior images of its upcoming e-tron electric SUV, including the cameras in the front passenger doors which will enable the world's first 'virtual' exterior mirrors.

The German car maker is eking out details of its highly anticipated zero-emission model ahead of its reveal in late autumn. It was originally due to be revealed at the Audi Summit in Brussels on 30 August, but this has been postponed due to 'operational issues' cited by the company. It is understood that the difficulties may stem from the arrest of suspended CEO Rupert Stadler.

The E-tron's most notable new technology - the virtual exterior mirrors - which will be optional, replace conventional door mirrors and project digital images onto screens located inside the car where the front doors meet the dashboard. They help to reduce the car's aerodynamic drag coefficient to just 0.28, claims Audi.

First ride: Audi e-tron 2018 prototype

These more compact exterior cameras combine with active aerodynamics and air suspension that can lower the car into its most aerodynamic position when cruising, giving the car a claimed drag coefficient figure that makes it 0.04 slipperier than the smaller Q2 SUV.

Audi says that without the e-tron's selection of drag-reducing features, the large electric SUV would be 21 miles shorter on range per charge. With them, the car is good for a 248-mile range, according to WLTP (which is a tougher test than the outgoing NEDC test). At the last Audi summit, a source confirmed to Autocar that a 500km (310 miles) range is possible. Acceleration will be on par with other Audi Sport models.

Audi's new official images show the car's aerodynamics at work - and demonstrate the minimal drag created by the small virtual mirrors.

That also suggests the e-tron will be badged 55 under Audi’s new naming system, which has been introduced to put combustion-engined, hybrid and battery-powered electric vehicles on an even footing in the hierarchy.

“We have decided to keep the e-tron name and use it like quattro,” an Audi source told Autocar. “The first of our sporty models was simply named the Audi Quattro. Our first all-electric car will simply be badged Audi e-tron.”

While powerful, the production e-tron’s output is less than the 496bhp quoted for the two concepts shown so far, because those featured a three-motor powertrain with a single front motor and twin rear motors.

However, the choice of a twin-motor layout at launch paves the way for Audi to introduce a performance e-tron powered by three motors a couple of years later.

Audi has mounted the car's lithium ion battery pack low in the floor, between the front and rear axles, to keep the centre of gravity as low as possible and maximise crash protection. The battery pack will use pouch-type cells packaged into 36 shoebox-sized modules.

Each module contains 12 pouches, supplied either by LG Chem or Samsung, and each rated at 60Ah; that's higher than those used by both Nissan and Tesla.

The bulk of the modules are in a flat main casing, but some are housed in a supplementary ‘saddle’ casing above the main battery and under the rear seat.

The battery is not light, though, contributing at least 700kg to the e-tron’s kerb weight.

A key part of the battery is a water-based ‘lattice’ cooling system, bonded to the underside of the modules to maximise heat transfer and shedding heat through a conventional, front-mounted radiator. A second heat pump system with a plate heat exchanger – in effect an air-con system – can boost cooling or heating to keep the battery at its optimum operating range of 25-35deg C in extreme climates.

The 150kW DC fast charger will take advantage of the Ionity rapid-charge network being set up by a consortium of Europe’s car makers.

Low carbon production

Production of the e-tron will begin later this year using what the company claims is a carbon-neutral production process.

Following the announcement that £1000 deposits are being taken for its first bespoke electric vehicle, Audi said that its Brussels factory, where the e-tron will be built, has been certified CO2-neutral. The facility uses renewable energy and offsets its carbon to enable what Audi claims is a waste-free process.

This will substantially boost the e-tron's well-to-wheel sustainability, giving the car an edge, environmentally speaking, over its electric rivals and setting a new bar for premium manufacturers.

Audi won’t yet discuss production or sales numbers for the e-tron, but IT says it has test-marketed the SUV in two European countries and reports potential demand for the model to be in the “double-digit thousands”.

Audi adopted the highly unusual tactic of unleashing four e-tron prototypes to prowl the streets of Geneva in March to fight back against the launch of the Jaguar I-Pace.

“The e-tron will be a game-changer for Audi,” said former marketing boss and interim CEO Bram Schot. “It’s our first electric model and it's going to be a volume model.”

The production e-tron will be revealed later this year as the first of three battery electric vehicles (BEVs) that Audi will launch by 2021. 

By 2025, the company promises to have 20 electrified models on sale, with half of those being BEVs.

Audi has also raised the possibility of Audi Sport-tuned versions of the e-tron. “The question is when,” said Schot. “The electric powertrain gives really good performance, so the driving experience gives such a good feeling.”

e-tron models could also be sold on a monthly subscription that would allow buyers to switch between Audi models to suit particular driving demands. “We're actively looking at every option,” said Schot.

On-sale date

Audi has previously said the e-tron will “cost about the same as a well-specced Audi A6”, suggesting it will have an entry-level price of at least £60,000. The I-Pace is priced from £58,995.

Audi sales and marketing boss Dietmar Voggenreiter said that Audi has chosen to launch the e-tron in 2018 because battery technology is now mature enough to be able to offer range that's usable in the real-world. Charging infrastructure is also now growing rapidly – another key reason for choosing a 2018 launch date.

“A 400-500km range must be possible and we must have a fast charging infrastructure,” said Voggenreiter. “Both things are coming in 2018. The battery energy density is there and there's already a lot of charging infrastructure in Europe, the US and Asia.” 

Voggenreiter said Audi was involved through the Volkswagen Group with rival firms such as BMW, Daimler and Ford in ensuring there’s a fast-charging network for longer-range electric vehicles to use.

“It’s not our job to invest in charging points,” he said. “We're pushing and organising this, though, and working with our partners on it.” 

Voggenreiter referred to the ‘chicken and egg’ situation of limited charging infrastructure to date; there has been no need for third parties to install chargers because there are not enough cars to use them, and vice versa. “No cars, no infrastructure, but in the next two years there will be lots of investments,” he added.

e-tron name

Audi has opted not to launch its electric cars under a sub-brand, in the way BMW has with its i models and Mercedes-Benz with the EQ range. Instead, it's using e-tron, which has been a suffix on Audi's hybrid cars, as a model name in its own right.

Voggenreiter said the e-tron name will be used on a range of follow-up electric and plug-in hybrid vehicles, where it will appear mostly as a suffix, as is the case with the existing A3 e-tron. It’s likely that Audi’s next-generation models will all get electric versions, while an A8 e-tron is most likely to be the first candidate.

An SUV body is important for the e-tron, because it's the most on-trend bodystyle, said Voggenreiter. “A lot of customers have been asking when we’ll bring this car to market,” he said. “There's certainly demand in the premium segment; it’s the right product. It’s a real SUV, with Audi design language.” 

Voggenreiter suggested that Audi's future range of e-tron models will have slightly different styling from the Marc Lichte-designed new look that's currently being rolled out across the rest of the brand's line-up. 

“The e-trons are close to the designs of Lichte but in different packages,” he said. “There isn’t an engine in the front.” 

The size of the e-tron suggests it’s a Q6 in all but name, but Voggenreiter hinted that the Q6 is a separate project. He cited speculation that the Q6 should be a “four-door SUV-coupé” based on the Q5, in a similar style to the forthcoming Q8 being spun off the Q7.

Voggenreiter said the e-tron isn’t the Q6 because it’s “not a four-door SUV-coupé, but a sporty SUV”.

Speaking at the 2017 Audi Summit, suspended CEO Rupert Stadler said: “It will have the best technology and be the most beautiful of electric cars." Commenting on Audi's electrified sales targets, he said: "By 2025 we will have 800,000 sales a year of electrified cars with electric cars and plug-in hybrids. Every third Audi will be electrified. All our production sites will be carbon neutral by 2030."

senior executive previously told Autocar would make it the “first real premium manufacturer doing a premium electric SUV" you gotta love VW. They must think the Model X is a celebrity in rehab.

And as to thinking people won't except less than 311 miles, pah

...as a SUV does not make it a SUV. I doubt whether folk would pay >£100K for a plush minivan, and that, I would suggest, is the reason why it's marketed as such.

Fair point. The I Pace isn’t an SUV either.

I suppose it’s the same as movies and live shows being labelled as ‘comedy’ to sell more tickets, even when they aren’t really comedies at all.

the Audi is an SUV then?

In fairness to both sides we're yet to find that out. But I'd put money on it being more capable then Model X. Not, as is often pointed out, that many owners will venture off the beaten track.

I think it's a fair enough analogy from the exec. It's like apple made the first premium smart watch, but whilst they're clearly a premium brand, they're not a TAG, Rolex et al established old school watch maker. I prefer the novel, but to some they like the established nature of the old. As for SUV/Minivan argument, half the SUV's out there never get further off road than the pavemnet and are set up as such.

This one has a tow bar on it. 

Much more useful if you are claiming to be an SUV to actually have some "utility"

16 August 2017
"first real premium manufacturer doing a premium electric SUV”. What a condescending wanker. Typical senior exec shite and the exact reason I left the motor industry. I really hope Tesla can survive and do some real damage to these short sighted head in the sand tossers.

With you on this, where did you go? Take me with you!

With an EV you need to build 15-20cm of batteries into the floor. An SUV body style neatly hides this. 

i expect neither the Jaguar or Audi to have any real additional ground clearance. For many people this won't matter.
