British SUV marque Land Rover, now owned by Tata Motors, has updated its flagship luxury SUVs for 2015. The Range Rover and Range Rover Sport luxury SUVs get new equipment and mechanical changes. Key mechanical changes on the 2015 Range Rover and Sport models include revised 3 liter TD V6, SD V6 and SC V6 engines. The two diesel engines, which displace 3 liters in a V6 layout, are equipped with single and twin turbochargers respectively.
The TD V6 engine loses the twin turbocharger layout for a single turbo while gaining a low pressure exhaust gas recirculation system, revised injectors and a twin stage oil pump that minimizes parasitic losses. The 3 liter TD V6 motor outputs 254 Bhp of peak power and 600 Nm of peak torque. Land Rover claims that the TDV6 diesel engine powering the Range Rover is about 8.5 % more fuel efficient than the older version.
The SD V6 twin turbo diesel engine makes 300 Bhp and 700 Nm, and is fitted to the Range Rover Sport model. This diesel engine gets all the changes of the TD V6 motor, including better fuel efficiency. The SC V6 supercharged petrol engine, gets power and torque outputs of 335 Bhp and 700 Nm. In the 2015 Range Rover Sport, this engine gains revised injectors, a twin stage oil pump, revised camshaft geometry, hard coating on piston and gudgeon pin and a new thermostat. Fuel efficiency is also said to have increased, albeit marginally at 1.9 %.
Another new feature on the 2o15 Range Rover and Range Rover Sport models include an All-Terrain Progress Control (ATPC) terrain response system that allows a driver to preset a certain speed for off road conditions and allow the SUV’s on board computers to automatically sense the terrain and modulate wheel speeds accordingly. The driver can take her or his foot off the pedals and allow the ATPC to take control on the vehicle’s forward and reverse movements.
Land Rover also offers a laser powered heads up display on both SUVs. Land Rover sells both the Range Rover and Range Rover Sport Luxury SUVs in India. Both SUVs are imported into the country as completely built units. The 2015 variants of the Range Rover and Range Rover Sport will be launched in India sometime next year.
