Sales of the large Range Rover are particularly low compared to Land Rover's targets. The reason is simple, customers seem to prefer rivals offering diesel engines with more torque and much lower fuel consumption. The British brand will rectify this by developing a new diesel engine.
The European Union's CO2 emission reduction targets for 2021 have only increased interest in diesel engines. For example, the old fuel-hungry 4.4-litre V8 diesel engine will be replaced by a smaller engine. It will be a 3.0-litre in-line six that will be coupled to a 48-volt battery.
Like all mild hybrid engines, you can't expect to drive a single mile using only electric power. The battery will actually assist the combustion engine in the acceleration phases, where fuel consumption is the highest. And the battery will recharge itself during deceleration by recovering kinetic energy.
CO2 emissions and fuel consumption are therefore expected to fall significantly. Emissions will drop below 200 g/km and actual fuel consumption will most likely approach 8L per 100 km (35 mpg UK/29 mpg US), which will be an excellent value for a vehicle of this size.
