After some speculation that Aston Martin's first SUV would be called Varekai, the company finally came out to confirm it will actually be called the DBX. Since then, Aston has been teasing us by showing off prototypes of the DBX undergoing various tests, such as drifting through the snow.

The DBX is set to benefit from Aston's deal with Mercedes-AMG and will pack a twin-turbo 4.0-liter V8 with 503 horsepower and 505 lb-ft of torque under the hood. And the horsepower won't be the only German item in this British SUV, all of the navigation and electronics will also be borrowed from Mercedes.

We've now seen several spy shots of the DBX, which allows us to glean information about the interior. This is still a prototype, so all of the test buttons, wires, the computer monitor, and the keyboard will not be present in the finished product. What we do notice is a significant amount of trim taken directly from a Mercedes, and not even the most recent of Mercedes interiors.

The steering wheel appears to be taken almost directly out of an AMG car and the power seat controls are pure Mercedes. Then there's the infotainment, which is the old Mercedes Comand system rather than the new Mercedes-Benz User Interface (MBUX). This means the DBX will go on sale with an outdated infotainment system rather than Mercedes' most recent technology.

Aston Martin has never had a reputation for including state-of-the-art infotainment systems in its vehicles, but it seems odd that the company was not able to procure the most recent system from Mercedes. The test mule in these spy shots was also seen hooked up to a small trailer, which could give us some insight into the DBX's towing ability. This is the first Aston Martin vehicle that could potentially be used for towing, though we'd place bets on few owners ever taking advantage of this capability.
