When does 5+3=4? Using Audi’s new math, that’s the sum one gets from the new Q4E-Tron crossover.

This marks the fourth e-tron electric vehicle and here, the company has mixed the compactness of its Q3 with the capaciousness of its Q5 in the same electrified crossover.

Should the model name ring any bells, it’s because Audi unveiled a concept vehicle in 2019 also called the Q4 E-Tron at the Geneva Auto Show. The production Q4 mimics the design study in that both are built on Audi-specific versions of the modular MEB platform, developed by Volkswagen and found under VW’s ID.4, among other models.

Autoblog recently had the opportunity to preview the upcoming crossover while still wearing camouflage. The headlights are larger while the rear is treated to new-look taillamps.

The Q4 is 180 inches long, 73 inches wide and 63 inches tall, which is on par with the Q3’s dimensions. However, the Q4’s front overhang is unusually abrupt because an electric motor uses less space than a four- or six-cylinder engine.

Michael Kaufmann, the project technical manager, informed Autoblog that inside, the cargo space is comparable to what the Q5 offers.

How much cargo space, you ask? With four people aboard, there is 18.4 cubic feet available behind the second row and 52.6 cu. ft. with the rear seat folded. There’s almost another cubic foot of additional storage sprinkled throughout the cabin, Audi noted.

Available goodies will include an augmented reality heads-up display (HUD). Beyond the typical projected driving information, the Q4 e-tron will superimpose navigation elements onto the windshield, which should make dealing with roundabouts and other, complex intersections easier. There will also be a steering wheel with touch-sensitive buttons on the spokes, a driver-configurable, digital instrument cluster and a standard 10.1-inch display or an optional 11.6-inch touchscreen for the MMI infotainment system.

Audi remains mum on the full tech specs, but what is known about the MEB offers a preview. There will be a lithium-ion battery pack directly beneath the cabin and the platform can take a single electric motor mounted over the rear axle or a twin-motor design. Different markets may receive different variants.

Full details will surface in April. Sales will start in the 2022 model year and buyers should expect the crossover’s base price to be north of $50,000.
