Right now, Mercedes only sells one fully electric model: the EQC SUV. This will soon change, however, as the German automaker's EQ electric range will rapidly expand within the next few years to compete with Volkswagen's ID. family.

The production version of the Mercedes EQS Vision will represent the automaker's flagship electric sedan. Slotting below it will be the Mercedes EQE, which will essentially be an electric version of the Mercedes E-Class. We got our first look at Mercedes' new Tesla Model S rival last month, and now our spies have captured the Mercedes EQE on video during cold-weather testing, allowing us to see it in action from all angles. It was also caught testing alongside the all-new Mercedes S-Class.

The Mercedes EQE prototype is still covered in camouflage to disguise the design details, but we can see it has smaller proportions than the EQS. There are also some subtle styling differences compared to prototypes we've seen of the EQS, such as different side mirrors and repositioned headlights. In the video, we get a brief look at the cabin as the test driver exits the prototype, but it's heavily covered up.

The steering wheel looks identical to the EQS prototype's wheel, which has also been spotted in prototypes of the new S-Class. In the final production model, we're expecting the interior to sport a fully digital gauge cluster and a huge Tesla-style touchscreen.

The production EQE will ride on Mercedes' Modular Electric Architecture. With the batteries stored under the floor, the electric EQE will offer more cabin space than its combustion-powered sibling. Powertrain details haven't been confirmed, but the EQE is expected to adopt a four-wheel-drive setup with an electric motor powering each axle.

This setup delivered a combined 469 horsepower and 560 lb-ft of torque in the Vision EQS, enabling it to hit 0-62 mph in 4.5 seconds and offer a driving range of 435 miles. Reports claim the Mercedes EQE will go on sale in 2022.
