It’s all about EQ for Mercedes-Benz at the upcoming Frankfurt motor show. We already know that the premium brand will be unveiling the “first, fully electric EQ concept vehicle within the compact car segment” at IAA, and here’s an official teaser of the compact EV concept.

The Mercedes-Benz EQ A, as it’s called, will be the starter car and volume seller of the EQ sub-brand for Stuttgart’s electric cars. It will sit under the EQ C, an SUV, when it debuts in 2020. The EQ C was previewed by the Generation EQ concept from Paris 2016, where Mercedes announced the EQ sub-brand. Recent trademark applications hint at future plans for an EQ E and EQ S electric flagship.

An Autocar report suggests that the EQ A’s driveline will feature a cheaper and simpler set-up than the EQ C – which could be a single front-mounted electric motor sending drive to the front-wheels via a fixed ratio gearbox. A performance version with the addition of a rear motor (for 4WD), as used in the EQ C, is a possibility, the report adds.

The UK mag’s sources also point to Mercedes-Benz’s compact car plant in Rastatt, Germany, as the factory that will churn out the EQ A on a dedicated EV line. The EQ C will be made at a separate plant in Bremen.

On the other end of the scale, the annual Frankfurt show will also see the world premiere of the Mercedes-AMG Project ONE, a two-seater showcar with Formula 1 hybrid tech, 1,000 hp and a top speed of over 350 km/h. The production GLC F-Cell EQ Power, a hydrogen fuel cell plug-in hybrid vehicle, will also make its bow.
