VW to Use BorgWarner Turbochargers for Diesel Engines

In order to increase performance and cut emissions as much as possible on diesel engines, German manufacturer Volkswagen turned to BorgWarner to equip its 2.0-liter diesel engine with regulated two-stage (briefly known as R2S) turbochargers. The 2.0-liter four-cylinder common-rail diesel engine is currently being used on VW's 180 horsepower Transporter T5 and the new 163 horsepower Amarok pickup.

Of course, both engines are capable of achieving impressive performance and emission levels, generating 400 Nm at only 1500 rpm and registering a fuel consumption rating of 31 mpg (7.5 l/100km).

"VW's commercial vehicles and pickups demand optimum power output and maximum fuel economy. BorgWarner's highly efficient R2S turbocharging technology delivers both with the added benefit of lower emissions," said Roger Wood, Executive Vice President, BorgWarner. "We value our successful long-standing partnership with Volkswagen and are pleased to collaborate on optimal solutions for powerful downsized diesel engines."

Curious how the two-stage BorgWarner turbocharger works? The company says its engineers used so-called two series-connected turbochargers to be sure that the engine receives high boost pressure at any given speed. The power-to-displacement ratio is 66kW per liter, according to official figures.

Of course, this isn't the first time when an automaker uses BorgWarner's turbochargers, as the company is one the main leaders of the industry. For example, it signed a partnership with Ford earlier this year to supply turbos for EcoBoost small units as well as for the 3.5-liter EcoBoost engine supposed to be installed on rear-wheel drive trucks.
