BorgWarner supplies the turbocharger for the all-alloy Si4 2.0-liter four-cylinder gasoline engine available in the all-new Land Rover Discovery Sport. According to the automaker, the 236-hp unit's compact design helps reduce weight and cuts CO2 emissions by up to 20 percent compared with engines with a similar power output.
All Si4 Discovery Sports are equipped with a nine-speed automatic transmission developed and supplied by ZF Friedrichshafen. The unit weighs 7.5kg less and is just 6mm longer than the six-speed transmission fitted to previous Land Rover models despite having an additional three gear ratios.
GKN Driveline supplies the new model with its three-piece propshafts, front sideshafts, power transfer unit and rear drive unit for the so-called Active Driveline system, available on selected diesel-powered variants. The system intelligently switches between two- and four-wheel drive as conditions dictate. Four-wheel drive is continuously engaged to provide traction from a standstill, but a clutch completely disconnects the propshaft, rear driveshafts as well as the rear differential and clutches during normal driving at speeds above 35kph. The reduction in friction contributes to the improved fuel consumption and CO2 emissions. Should the system detect wheel slip or a more dynamic driving style, four-wheel drive is re-engaged within 350 milliseconds.
Assembly of the new model began at Land Rover’s plant in Halewood, England, in October 2014. Output is forecast to peak at more than 84,000 units in 2016, according to IHS Automotive.
