Mercedes Biome Concept

At the 2010 Los Angeles Design Challenge, the designers from the Mercedes-Benz Advanced Design Studios in Carlsbad, California, surprised everyone with a revolutionary vision. Taking their inspiration from nature, they designed a vehicle which is fully integrated into the ecosystem, from the moment of its creation right through to the end of its service life.  Out on the road the car emits pure oxygen.

A super secretive Gumpert model was headed to the 2012 Geneva Motor Show and when the wraps came off, onlookers were made privy to the luscious, new Apollo R and a scintillating special edition, the Apollo Enraged. The Apollo Enraged not only succeeded in being kept a secret until only a day before Geneva, but it will also succeed at being one of the most exclusive (the sole Aventador J takes the cake on exclusivity) with only three units being produced of the super car.
