Come late 2014, the Volkswagen Golf, Beetle, Passat and Jetta will offer a new turbo-diesel four-cylinder engine that could get as high as 46 mpg highway in EPA figures. Final numbers are still pending, but Volkswagen announced that its new turbo-diesel four-cylinder — dubbed EA288 — will replace the existing turbo-diesel four-cylinder (shown above) in TDI versions of all four 2015 models.
Volkswagen notes that it has sold more than 47,000 diesel cars in the U.S. year to date, which represents more than three-fourths of all diesels sold here.
The engine has similarities to its predecessor — turbocharging and direct injection — and it should have the same 2.0-liter displacement, spokesman Mark Gillies told us. Beyond that, Volkswagen says it has a slew of new features, including better exhaust-gas treatment, numerous friction reductions and integration of the intercooler with the engine’s intake manifold. If that’s all Greek to you, VW says the end result should improve gas mileage and sharpen accelerator response. The new diesels also have slightly more oomph: 150 horsepower versus the outgoing TDI’s 140 hp. Torque remains the same, with a diesel-appropriate 236 pounds-feet.
