The power output from this power plant is an acceptable 254 horsepower, but with all diesels, the strength of the engine can only be judged by its torque output. In the two Range Rover models, the engine produces a competitive 440 lb.ft. of torque at 1750 RPM, which places it right in between the Audi Q7 3.0 TDI, BMW X5 3.0 TDI and Mercedes-Benz GL 350 BlueTec. Like its gasoline counterparts, the diesel Range Rover models come standard with ZF sourced eight-speed automatic transmission with paddle shifters.
0 to 60 MPH is achieved in 7.1 seconds for the Range Rover Sport and 7.4 seconds for the Range Rover. The gasoline powered V6 Range Rover Sport and Range Rover complete the task in 6.9 seconds and 7.1 seconds. This means the difference between the two versions is only 0.3 seconds.
Thanks to the new diesel engine, the Range Rover and Range Rover Sport see an increase in fuel efficiency of 32% when compared to the gasoline V6 engine. The overall fuel mileage also increases to 22 city, 28 highway and 25 combined. With this new found efficiency, the two Range Rover models can now travel up to 658 miles on a single tank of diesel.
The TDI V6 is a whole new design constructed out of compacted graphite which is more durable compared to the traditional iron and aluminum engine blocks. This engine has been available to global consumers for the past two years already, but before it makes its debut on American shores, Land Rover engineers have made minor modifications to make the engine compatible with the strict American efficiency standards.
Around the world, Range Rovers are know for their luxurious features and not for their diesel engine clatter. So, the engineers have added dual-isolation engine mounts and acoustic laminate windshield to reduce the engine noise as much as possible. Also, to avoid confusion at the gas pump, the fuel filler module has a devise which prevents the narrower gasoline nozzle from entering the tank and only permits the larger diameter diesel fuel nozzle.
After years of asking, the Range Rovers are finally available with a diesel engine, but we are not sure if their timing was right or not. With the sharp decline in recent fuel prices, the advantages the diesel engine offer are almost nonexistent. With Premium Fuel averaging around $2.40/gallon and diesel still at or around $2.89/gallon, many consumers might find it hard to justify the additional costs of owning diesel powered Range Rovers over gasoline powered versions, but if your lifestyle includes a lot of commuting and you don’t like the concept of frequent fuel stops, then the diesel Range Rover is a no brainer.
