Mercedes and BMW are building
electric supercars, but Audi won’t be. Here’s why
The Audi R8 E-Tron won’t be hitting
showrooms like the BMW i8 or the Mercedes AMG SLS Electric Drive. So is the R8
E-tron a dud or an opportunity missed by Audi?
The electric version of the R8 carries 577
kg of lithium-ion batteries, but its 1,780 kg weight is only 210 kg more than
an R8 V10’s, thanks to extensive use of aluminum and carbon-fiber throughout
the lighter, stiffer shell. You might notice that there’s the race LMS
version’s carbon bonnet with its deep vent, too, and that the rear window’s
been binned to increase rigidity and save weight.

Instead of the cackling V8 or snarling V10
behind your head, the T-shaped battery pack mounted behind the seats is joined
by an electric motor for each of the rear wheels. They operate each wheel
individually, while the whole set-up is liquid-cooled to ensure it delivers the
full 380 PS.
At the wheel, other than the 6.8-mm TFT
screen that acts as a mirror and the instruments which measure the amount of
brake regeneration, it’s standard R8 fare.

It’s when you mash the pedal that you
realize this electric car is a little bit special. The 4.2-second 0-to-100 km/h
time isn’t as quick as the V10’s 3.9 seconds, but the punch is awesome, with
819 Nm of torque (substantially more than the V10’s 398) on tap from a single
RPM.
Audi have made some cars that lack the
involvement they promise (we’re looking at you, RS5), so you’d expect an
electrified R8 to have lost the plot once it reaches a corner – it hasn’t.
Sure, against the V10, the electric whir is like comparing porridge with prime
rib, but the sharp turn-in, nicely weighted steering and playfulness are a
boon.

The E-tron doesn’t feel heavy at all, while
the brakes don’t have that woody, on-off character like many electric cars,
instead cleverly ‘blending’ electric and mechanical systems to squeeze a
quartet of carbon-ceramic discs. This means a progressive pedal so you can set
up the R8 for a corner and exploit the front-end grip. It’s fun even in the
‘Efficiency’ mode, but choose ‘Dynamic’, switch the ESP off and the E-tron
shows its ability and flatters yours.
Here, entry speeds are up, as is mid-corner
pace for much faster exits, all thanks to the clever electric torque-vectoring
set-up. The system not only brakes each of the rear wheels individually, but
accelerates them when needed, too. This gives rock-solid stability under hard
braking and, along with special 19-inch tires, lets you push hard out of
corners with unshakeable composure. This is an easy car to hustle and makes you
feel like a great driver.

Now, the bad part. After a 12-hour charge,
the 214-km range is paltry and you won’t get near it on the track. Then there’s
the price: each has cost Audi $1,315,500 to build, which means it doesn’t add
up for Ingolstadt’s bean counters.
So while the e-SLS is not as engaging to
drive, sadly it’s the R8 E-tron that hits the cutting room floor.
