Mercedes had a single goal: create a single concept vehicle that could travel 1,000 kilometers (621 miles) on a single charge from a battery pack slightly smaller than 100kWh.

And the result was the EQXX, a coupe that looks as good as the best technology that powers it.

Typically these vehicles are off limits to anyone outside of a select few within the automaker. 

But Mercedes decided to let us get behind the wheel for a test drive.

Designed to glide through the air with as little drag as possible, the EQXX doesn't wow with off-the-line performance. 

Instead, the power really comes after you get up to highway speed. But even so, the concept car is an efficient machine that feels futuristic. 

Mercedes has no plans to put the EQXX into production, but what it's learning now will make its way into its vehicles at some point.
