2017 Audi R8 e-tron All-Electric Sports Car: Live Photos From Geneva Motor
Show

The all-new Audi R8 sports car was officially unveiled today at the Geneva
Motor Show, including the limited-production R8 e-tron battery electric
version.

Audi had previously released some advance information—including the first
official details—about the all-electric R8 e-tron sports car that will soon
follow the gasoline version, likely as a 2017 model.

The R8 e-tron information arrived earlier than expected; company officials
previously suggested that new electric and plug-in hybrid versions of the
R8 would appear some time after the base car’s launch.

Given the timing on details, we suspect the all-electric e-tron could be
mere months behind the gasoline model's anticipated late-summer market
launch.

Such a car would compete with the BMW i8, as well as with several niche
models, like the Detroit Electric SP:01.

And the plug-in hybrid version of the R8 that's also on the way might be
compared with the i8 and the upcoming Acura NSX, a hybrid sports car that
will also have a mid-engine layout.

This is the second version of the R8 e-tron. The previous version was
on-again, off-again for several cycles as Audi struggled to get the car’s
packaging and battery technology right.

*Much larger battery*

The previous 49-kilowatt-hour battery pack simply wasn’t going to cut it in
a high-performance sports car.

To provide for a German necessity—the Autobahn—the previous version simply
wouldn’t maintain speeds close to its 124-mph top speed for longer than
about 20 minutes.

(Jan 2014)*

With a much larger 92-kWh battery pack (nearly four times the capacity of a
Nissan Leaf), the new R8 e-tron should finally carry enough energy onboard
to deliver strong performance, or return a much-improved driving range of
280 miles.

That’s far more than the previous version’s 134 miles; on the performance
side it makes around 455 horsepower and up to 679 pound-feet of torque.

It can accelerate to 62 mph in 3.9 seconds, or reach a governed top speed
of either 131 mph or 155 mph. A coefficient of drag of just 0.28 helps with
that.

The R8 e-tron will have rear-wheel drive, with “targeted torque vectoring”
between the rear wheels, plus an electromechanical brake system aimed at
high brake-regeneration rates.

Expect DC fast-charging hardware using the CCS protocol, too—which might
make this sports car an interesting touring possibility in some West Coast
U.S. regions once more CCS chargers are in place.

Just as with the gasoline-only versions of the new-generation 2016 Audi R8,
the e-tron will be built on a new multi-material Audi Space Frame,
including “high proportions” of aluminum and CFRP (carbon-fiber-reinforced
polymer/plastic).

In 2017

The body shell and multi-material Audi Space Frame weigh just 441 pounds
altogether.

Audi notes that CFRP is used around the car’s middle side pillar, its
central tunnel, and the rear wall—and altogether torsional rigidity is 40
percent better than that of its predecessor.

*Weight savings: carbon fiber, better energy density*

Fitting that large, T-shaped battery pack required some packaging ingenuity
as well.

The pack is structurally integrated within the center tunnel, just behind
the occupant cell, and the automaker notes the energy density has been
increased from 84 Wh/kg to 154 Wh/kg.

The pack, produced by Audi, is “based on a newly developed lithium-ion
technology which was specially conceived for a purely electric vehicle
drive.”

Other design and technology details include LED headlights, an all-digital
‘virtual cockpit,’ and an instrument panel that has ‘floating’ climate
controls in the midst of vents, as in the new Audi TT.
