A Volkswagen Group of America executive revealed news of a new-generation TDI engine this week during a speech delivered at the Management Briefing Seminars in Traverse City, Michigan. Oliver Schmidt, General Manager, Energy and Environmental Office confirmed that the company’s new EA288 2.0-liter TDI will replace the existing 4-cylinder diesel in several group models including the upcoming Audi A3 sedan due in the first half of 2014.
This new EA288 is a turbocharged, common-rail, direct-injection four-cylinder that produces 150 horsepower and 236 lb-ft of torque. It marks an increase of 10 hp over the current 2.0 TDI sold in the USA. And even though it is also a 2.0-liter TDI, EA288 shares only bore spacing with the previous generation North American 4-cylinder TDI engine. Further improvements also includes a high pressure EGR and a cooled low pressure EGR, integration of the water-cooled intercooler and the EGR valve with the intake manifold that improves throttle repsonse. Exhaust after-treatment components are also packaged close to the engine by combining the DPF with the SCR Catalyst. Friction is minimized through the use of low-friction bearings for camshaft and balancer shafts, lower pre-tension piston rings and a two-stage oil pump with volumetric flow regulation each further minimize friction and thus optimize fuel economy.
Up until now the only Audi to use the older generation 2.0-liter TDI has been the A3 TDI in Sportback bodystyle sold through the 2013 model year. The new EA288 will debut with the MQB-based A3 sedan when it launches early in 2014 and a front-wheel drive A4 2.0 TDI has been rumored for America with the next-generation B9 A4.
“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. “
A release from the Volkswagen Group stated, “The announcement underscores Volkswagen Group of America’s continued success with diesel technology: Year-to-date the Volkswagen Group of America has sold more than 47,000 clean diesel vehicles, including more than 10,000 in the month of July alone. This represents nearly 78 percent of the diesel sales for passenger cars in the United States this year.”
