With just over a week to go until the new Mercedes-Benz GLA's world debut on December 11, the teaser campaign for the new entry-level SUV is shifting into high gear. Last week, Mercedes showed off the new GLA's silhouette, and now we're getting a peek inside the cabin for the first time.

We hope you weren't expecting any surprises because the interior looks very similar to other recent compact Mercedes models such as the new A-Class Sedan, which the new GLA will share its platform with. The teaser photo shows the new GLA will have a virtually identical steering wheel, air vents, and digital dashboard to the A-Class.

It also showcases the automaker's blind spot assist with exit warning functionality. In the scenario shown in the photo, a cyclist is approaching the car and is visible in the side mirror. When the driver is about to exit the stationary car, the system activates a warning tone and warning lamp in the outside mirror if it detects an approaching vehicle or cyclist.

However, the exit warning function is only available when blind spot assist is activated and up to a maximum of three minutes after the ignition has been switched off. The exit warning is also no longer available once the warning lamp in the outside mirror flashes three times.

Compared to the outgoing GLA, the new model will be 3.9 inches taller allowing for more headroom and a higher seating position, and 0.59 inches shorter. Despite this, the new Mercedes GLA will offer more generous rear legroom than its predecessor. Teaser photos demonstrating the GLA's off-road capability also showed off the SUV's short overhangs at the front and rear, and protective cladding all-round. According to Mercedes, the new GLA will be offered with a Driving Assistance package, which includes active brake assist, cornering function, emergency lane function, exit warning, and pedestrian warning.

Under the hood, the GLA will likely be offered with a 2.0-liter turbocharged four-cylinder engine producing 220 horsepower paired with a seven-speed automatic transmission. More powerful AMG and plug-in hybrid variants will also join the lineup.
