POWERFUL DIESEL ENGINE SETS NEW STANDARDS FOR PASSENGER CARS

Powered by BorgWarner's (Auburn Hills, MI) regulated two-stage (R2S®) and variable turbine geometry (VTG) turbocharging technologies, the new 740d boasts BMW's most powerful 3.0 liter straight six-cylinder diesel engine, while improving fuel economy up to 4 percent compared with its predecessor. For the first time in a passenger car, the combination of direct fuel injection plus R2S® and VTG turbocharging sets new standards in improved performance and torque as well as reduced emissions and increased fuel economy. Accelerating from 0 to 62 mph (100 km/h) in just 6.3 seconds, the BMW 740d achieves a combined 34 mpg (6.9 liters/100 km) and meets Euro 5 emissions standards.

"BorgWarner's highly efficient turbocharging technology meets the highest demands for powerful performance, fuel economy and emissions," said Roger Wood, executive vice president of BorgWarner. "BMW was the first to introduce BorgWarner's R2S® technology in a diesel passenger car. We are pleased to continue our long-standing relationship with BMW with the introduction of our latest advancement."

Working with BMW, BorgWarner united two advanced technologies to accelerate BMW's engine downsizing strategy without compromising power and torque. BorgWarner's R2S® turbocharging system consists of two series-connected turbochargers. By applying BorgWarner's VTG technology to the smaller turbocharger, the engine responds spontaneously at low engine speeds for instant acceleration. As the engine reaches mid-range speeds, the larger low-pressure turbocharger takes over, providing the boost pressure to reach the maximum engine torque of 600 Nm at 1,500 rpm and a top output of 225 kW/306 horsepower at 4,400 rpm. The combination of technologies achieves both high torque at very low revs and maximum output at high engine speeds while reducing fuel consumption and emissions to a much lower level.

BorgWarner's patented R2S® technology has received several awards, including a 2008 Automotive News PACE Award and the 2008 Automotive News PACE Environmental Award. BorgWarner received a 2007 Automotive News PACE Award for its VTG turbocharging technology. BorgWarner Turbo Systems is a leading global manufacturer of turbochargers, exhaust gas recirculation valves and other engine air management systems for passenger cars, light trucks and commercial vehicles. These systems are designed to improve fuel economy, reduce emissions and enhance vehicle performance.
