Mercedes-Benz will be revealing its Vision Sports Tourer concepts ‘R’ and ‘B’ at the Paris Motor Show this month.

The Sports Tourers will be equipped with high-torque CDI diesel engines. In the Grand Sports Tourer ‘Vision R’ a new V6 power unit will be fitted, producing 218bhp.

The Grand Sports Tourer ‘Vision R’, which Mercedes-Benz is presenting in its European version in Paris, is designed as a 4+2-seater.

The new concept will feature four-wheel drive, air suspension and new V6 diesel engine.

Equipped with the 7G-TRONIC seven-speed automatic transmission, the 218bhp six-cylinder engine manages 32mpg. The exhaust emissions meet the EU IV standards, and the particulate filter system developed by Mercedes-Benz also reduces soot emissions.

The Compact Sports Tourer ‘Vision B’ has its engine and transmission partly in front of and partly beneath the passenger area, which Mercedes says ‘gives this all-new touring car the interior spaciousness of larger saloons and estates despite its compact external dimensions’.

The compact Sports Tourer is powered by a new four-cylinder diesel engine with an output of 140bhp. Other attributes are a fuel consumption of over 47mpg and exhaust emissions at EU IV levels. A diesel particulate filter is also included.
