“thrilling experience” for the venerable<br />
rally legend. The difference, that is,<br />
between a combustion engine with<br />
quattro drive, which is controlled<br />
through the transmission and<br />
differential, and the electric quattro<br />
drive with four motors. “It’s incredible<br />
how the technology has developed, so<br />
that you can have a driving experience<br />
that comes extremely close to that of<br />
driving the original quattro,” he said.<br />
Blomqvist jerks the steering<br />
wheel to the right and brakes<br />
with his left foot.<br />
Blomqvist became famous not only<br />
as a rally driver, but also for braking<br />
with his left foot. In the early 1980s<br />
the Swede mastered like virtually no<br />
other driver the <strong>trick</strong> of braking with<br />
the left foot while simultaneously<br />
applying the gas with the right. This<br />
allowed him to maintain high revs<br />
and keep the engine’s output up,<br />
although he was braking. In addition<br />
to many victories, this <strong>special</strong> <strong>trick</strong><br />
brought Blomqvist the World Rally<br />
Championship in 1984 and the runnerup<br />
title the following year.<br />
Now he tries this <strong>trick</strong> out in the<br />
Audi e-tron Silvretta on the snowcovered<br />
test track in Munich. He’s too<br />
much of an old pro to not at least give<br />
it a shot. He jerks the steering wheel<br />
to the right, brakes with his left foot<br />
and applies the accelerator with his<br />
right. Now the butt instinct informs<br />
the driver that the Audi e-tron Silvretta<br />
wants to break loose each millisecond.<br />
But it doesn’t. “It won’t work,” said<br />
Blomqvist. “The ESP can’t be switched<br />
off. Those spectacular drifts aren’t<br />
possible.”<br />
Blomqvist stops at a charging<br />
station, climbs out of the Audi e-tron<br />
Silvretta and insists on plugging<br />
the electric cable himself into the<br />
plug behind the side window, with<br />
utmost care. “That will be the biggest<br />
adjustment,” he said, looking into the<br />
distance. “Filling up is just faster than<br />
charging up. But who knows what Audi<br />
will think of by the time electric cars<br />
start series production”<br />
After a 20-minute stop for electricity,<br />
Blomqvist wants to go at it again. Alone.<br />
In peace. Just the Audi e-tron Silvretta<br />
and him. On an open area and without<br />
limits. Blomqvist swings himself into<br />
the driver’s seat. Again he puts on the<br />
reading glasses, and again the searching<br />
look. Then snow swirls into the air.<br />
The Audi races away, traveling down<br />
the track at high speed. But without<br />
the usual sound. <br />

Torque vectoring<br />
Perfect torque<br />
Torque is the most highly prized<br />
force in a car. It’s what moves<br />
us forward. The higher the value<br />
in Newton meters, the more<br />
powerfully the car can move at<br />
a specific number of revs.<br />
Torque can also come into<br />
play at inopportune moments<br />
when we drive too quickly in a<br />
curve or a highway exit. In these<br />
cases, the path we are taking can<br />
quickly deviate from that which<br />
we should take. To keep that<br />
from happening, Audi drivers get<br />
help from both the electronic<br />
stabilization program (ESP) and<br />
from torque vectoring.<br />
While ESP keeps the car on the<br />
right track while braking, torque<br />
vectoring takes the opposite<br />
approach: It distributes torque<br />
to each wheel electronically,<br />
thereby preventing wheel<br />
spin. Faster than a blink of the<br />
eye, power is distributed to<br />
the front and rear wheels via<br />
multi-plate clutches on the<br />
individual wheels, in such a way<br />
that the Audi stays on track.<br />
This is true both when actively<br />
applying the accelerator or when<br />
simply allowing the car to coast<br />
downhill.<br />
