Coming to America: Land Rover Confirms Range Rover Diesel Duo in Fall 2015

At the North American International Auto Show today in Detroit, Jaguar Land Rover North America announced it would (finally) bring diesel power to the American lineup, beginning with the 2016 Range Rover and Range Rover Sport.

Power for both models will come from a 3.0-liter turbocharged V6 (Td6) that will combine ample horsepower, prodigious torque, and never-before seen fuel economy, just as it has already in other markets. Output is rated at 254 hp and 440 kb-ft, with peak torque available at 1750 rpm. EPA highway fuel economy is expected to be 28 mpg, allowing for more than 650 miles of range.

Numerous changes have been introduced to prepare the engine for the American market, mostly in the turbocharger itself, resulting in an eight-percent gain in efficiency.

The block itself is formed not from aluminum, but from Compacted Graphite Iron. This material is stiffer and has better fatigue strength than aluminum, as well as higher tensile strength than traditional grey iron.

The emissions system employs urea injection for selective catalyst reduction. Diesel exhaust fluid (DEF) is stored onboard  in two locations, with enough capacity to treat the vehicle for approximately 10,000 miles of driving. As with other new diesel vehicles, the fuel filler neck will include a misfueling protection device, preventing gasoline nozzles from entering the stream.

Land Rover has taken measures to ensure that the engine is as quiet as it is muscular, long a point of contention with American buyers.

With so much torque available at such low engine speeds, these new versions should make excellent off-road companions. Towing capacity should be excellent as well, and there’s no denying the appeal of a more efficient Rover.

It is conceivable, though not confirmed, that the same engine could find its way into the next-generation Discovery and the upcoming Defender replacement.

Both the Range Rover Td6 and Range Rover Sport Td6 will be available in the fall of 2015 as 2016 models. Pricing has not yet been announced.
