News: New TDI Diesel coming to 2015 VW or Audi near you

2015 vw golf tdi diesel video review

The updated TDI diesel engine, designated EA288, is coming to a Volkswagen dealership in the second half of 2014.  The new turbo-diesel makes its debut in the 2015 model year Mk7 Golf, Jetta, Passat, Beetle, and Beetle Convertible.  The new motor makes 10 more horse than before for a total of 150 hp, while the torque output remains the same at 236 lb-ft.  This engine will also be used in Audi vehicles, like the 2015 Audi A3.  Eventually, the EA288 will spread across more and more Audi and VW models that can accommodate it.  So, you will likely see it in the next generation A4 and hopefully other VW Group vehicles.

The new powerplant may sounds very similar to the outgoing unit, but it shares only the displacement and bore spacing with the current 2.0L TDI.  Volkswagen worked hard to reduce emissions, increase efficiency, and improve throttle response.  Hence the use of a complex exhaust gas recirculation system; an intercooler integrated with the intake manifold, and packaging the exhaust after-treatment components close to the engine.

Volkswagen and the EPA are mum about the MPG estimates for the new diesel, but it does use low-friction bearings for the camshaft and balancer shafts, piston rings that have less pre-tension, and a two-stage oil pump with flow regulation.  Basically, components have been reworked and enhanced to provide incremental improvements.  The current VW Golf TDI is rated at 30 MPG city and 42 MPG highway, and the new engine needs a substantial increase in efficiency to keep diesel power viable.  Cars like the 2014 Ford Fiesta 1.0L EcoBoost are challenging the TDI to a battle of efficiency.
