Renault has pulled the covers off its new Master, which will be available with more efficient and powerful twin turbo engines.

The chief evolution is to be found under the Master’s bonnet, as a choice of 2.3 dCi engines with power outputs ranging from 110 to 165 horsepower (compared with 100-150hp previously).

The 135hp and 165hp versions will be equipped with Twin Turbo technology and, in addition to being more powerful, will be even more fuel efficient. The 165hp version, for example, will provide a fuel-consumption saving of 7.3 mpg* despite delivering 15 extra horsepower and 10Nm of additional torque. This will bring the fuel consumption of the L2H2 165hp version of New Master up to more than 40 mpg  (40.9 mpg, equivalent to 180g of CO₂/km).

Fuel consumption can be improved even further by up to 10 per cent by pressing on the ECOmode button which adjusts engine torque and the climate control/heater system’s settings.

The range also includes a number of new safety- and comfort-related features, including latest-generation ESC with Load Adaptive Control as standard equipment, as well as Hill Start Assist and Grip Xtend which optimises grip in difficult conditions, such as snow, mud and sand.

Trailer Swing Assist will also be available (in association with the towing option). When swaying of the trailer is detected, the system alternately applies the brakes and limits the delivery of engine torque until the phenomenon is halted.

The range now offers more than 120 versions in the UK, with a choice of four lengths and three heights, panel van, crew cab, platform cab, chassis cab, tippers, dropside and box van variants, as well as front- and rear-wheel drive, for a carrying capacity of between eight and 22 cubic metres.

New additions are the L4H2 and L4H3 panel van versions with single rear wheels.

The revised van will be available in Renault’s UK dealerships from the end of summer 2014, and order books are due to open in June.
