We can’t get enough of the Audi e-tron. It’s not a traditionally exciting car for a lot of Audi enthusiasts, who are used to highly powerful, turbocharged monsters. However, the e-tron is a new way of thinking ofr the brand ad it’s incredibly impressive in its own right. Especially when you consider it’s Audi’s first true effort into the world of EVs. In this new video from Audi USA, we get to listen to Joachim Doerr, an engineer for the e-tron’s electric drivetrain, discuss its motors and axles.
The Audi e-tron uses two electric motors at each axle, giving it real-time torque vectoring all-wheel drive. Listening to Doerr talk about how they work together is quite interesting, as it’s actually more effective than Audi’s traditional Quattro system. Rather than having power send to a Torsen diff to then be distributed to different axles via driveshafts and differentials, it’s just an instantaneous application of power to whichever axle needs it most.
So in any situation, the Audi e-tron is going to be better equipped, grip-wise, than even the most high-performance Audis on the market. It puts its power down instantaneously and more accurately than even the Audi R8, the brand’s most expensive car.
He also talks about the cooling of the new electric axles. During the launch of the Audi e-tron, the brand was very proud of its cooling capabilities and the e-tron does boast more impressive battery and motor cooling than any other EV on the market. It’s what allows the e-tron to do successive 0-60 mph sprints without overheating the batteries, like one some other EVs *cough* Tesla *cough*.
If you’re a tech nerd, this video is interesting to watch. It’s short, so it’s not jam packed with info, but it does give you the gist of how a couple of the Audi e-tron’s systems work, directly from one of its engineers.
