Total system output is 340PS (335hp) and 700Nm (516 lb-ft) of torque, allowing for a sprint to 62 mph (100 km/h in under 7 seconds. Average fuel economy is rated at 44.1 mpg UK (36.7 mpg US, 6.4 l/100 km).

The Range Rover Sport gets the powerful 334hp SDV8 diesel engine with a new sump, new cast alloy engine mounts and optimized calibration. Mated to the same ZF 8 Speed automatic gearbox, it delivers 700 Nm of torque and helps the Sport accelerate to 100km/h in 6.9 seconds and has a top speed of 225km/h.

The upgraded models will be available to order from September 10, with deliveries starting from early 2014.
