Audi's venture into producing its first mass electric vehicle (EV) is looking up it seems. Last month, our spies were able to take pictures of the upcoming e-tron quattro being driven on public roads. Based on the photos, its design will remain faithful to the original concept and could possibly be able to tow heavy payloads.

Now, it appears Audi is busy testing the e-tron quattro's agility and speed as it was recently spotted by our spies lapping the infamous 'Green Hell'. Looking at the images, Audi's all-new EV crossover appears quite agile around the corners. With most EVs known for being quite hefty (due to weight penalty caused by the batteries), it looks like Audi was able to fine tune the e-tron quattro's handling.

As for its exterior, the prototype EV is still heavily camouflaged but it's clear that Audi kept most of the concept's design intact for the production version. Still present up front are the slim headlights and the new Singleframe grill. Towards the side, it comes with a sleek roofline along with black plastic body cladding that runs the entire length of the crossover.

It's unclear whether the rear will get a redesign, but like the rest of it's body, it might still resemble the original concept's looks. Unusual however, on this particular prototype are its different set of wheels. This could mean Audi changed the tires for this particular test to check out how much grip the e-tron quattro can make.

In concept form, the e-tron quattro was powered by three electric motors that generate a combined output of 435 PS (503 PS with overboost function). It can go from 0 – 100 km/h in 4.6 seconds and reach a top speed of 203 km/h. It also has a maximum range of 500 km.

For now, the production version will reportedly retain the 500 km electric range though there is no word yet whether it will still produce 435 PS.

It is set to make its world debut some time in 2018.
