The Mercedes-Benz Viano (formerly known as the V-Class) is a multi-purpose vehicle based on the popular Mercedes-Benz Vito commercial panel van. The first generation went on sale in 1996; it is presently in its second generation, having undergone a number of changes - including a new name - in 2004. The Viano is a rear-wheel drive minivan available in three lengths, two wheelbases and a choice of four standard, modern petrol and diesel engines (as well as two specialist tuned models) coupled to either a six-speed manual or five-speed TouchShift automatic transmission. In some countries a camping derivative is available - known as the Marco Polo - which comes with a galley, wardrobe and individual seats in the rear which transform into a bed at the push of a button. Six individual seats come as standard, however up to two rear three-seater benches can be purchased, turning the Viano into an eight seat people carrier.
