Could it be Mercedes' fourth debut?.
Mercedes-Benz has a secret world premiere at 2015 Geneva Motor Show, as per Mercedes Passion Blog, who have pictures of a V-Class
Reportedly named the Mercedes 'Concept V ision e', the vehicle appeared briefly yesterday while the final touches were given to the booth. The website claims that there is a charging socket on the vehicle, substantiating the possibility that the concept is a plug-in hybrid.
Though the badges are taped, the report says the V ision e would preview a production plug-in hybrid variant. Currently the people mover is available solely with a 2.1-liter diesel engine with outputs falling between 136 hp and 190 hp, and can optionally be fitted with an all-wheel drive system.
It adds that the concept would have just 4 seats with memory functions and a wooden floor.
Mercedes will also host the world premieres of the AMG GT3, G 500 4×4² Concept and the Mercedes Maybach S600 Pullman tomorrow at the Swiss fair.
