2015 Volkswagen Golf - New York

Volkswagen plans to launch a new diesel engine that will ultimately replace the current 2.0-litre TDI in all its Audi and Volkswagen applications.

The new engine, designated EA288, will be offered in North America in the 2015 Golf, Beetle, Jetta and Passat, which are scheduled to go on sale in the second half of 2014.

The 2015 Golf, which made it North-American debut at the New York International Auto Show this spring, is already on sale in other markes and has been voted the 2013 World Car of the Year.

The new engine was announced by Oliver Schmidt, general manager, Energy and Environmental Office at Volkswagen Group of America, during a speech at the Automotive Management Briefing Seminars in Traverse City, Michigan.

The new EA288 is a turbocharged, common-rail, direct-injection four-cylinder engine that produces 150 horsepower – an increase of 10 hp over the current engine – and 236 lb-ft of torque.

It is said to share only its bore spacing with the current diesel engine that shares the same designation.

Multiple changes have been made to help reduce emissions, including: use of a complex exhaust gas recirculation system (with high pressure EGR and a cooled low-pressure EGR); integration of the water-cooled intercooler and the EGR valve with the intake manifold, which also improves throttle response; and packaging the exhaust after-treatment components close to the engine by combining the particulate filter with the SCR Catalyst.

The engine also has a number of modifications to help minimize friction and optimize fuel economy. They include: low-friction bearings for the camshaft and balancer shafts; piston rings that have less pre-tension; and a two-stage oil pump with volumetric flow regulation.

"The Volkswagen Group is a leader in clean diesel technology," said Schmidt. "With the introduction of the new EA288 engine, we are excited that our family of TDI Clean Diesel vehicles is continuing to improve and will be even more clean, fuel efficient and powerful. "
