VW’s Geneva show launches include a Golf TDI Hybrid concept offering 83 mpg and 89 g/km of CO2 emissions.

It will also display a new Scirocco sports coupé, a natural gas-fuelled Passat Estate TSI EcoFuel, a BlueMotion version of the Sharan giving 45.6 mpg and 10pc lower CO2 than its nearest equivalent, and the previously publicized Passat CC four-door coupé.

The Golf TDI Hybrid concept combines a 1.2-litre 75 hp diesel engine with an electric motor and seven-speed DSG gearbox. It is capable of achieving 83 mpg on the combined cycle and emits 89 g/km of CO2 – while around town the vehicle reverts to purely electric mode. VW has not confirmed when or whether this car will be launched commercially.

The Passat Estate TSI EcoFuel features a 150 PS TSI engine which has been specifically designed to run on natural gas, and consumes 5.2 kg of gas per 100 kilometres.
