The clean diesel V6 you see above will supposedly find a home under the hood of the Nissan Maxima sometime in 2010. Back in April in 2007, Nissan announced it would offer an oilburner in the Maxima, but that was before the price of diesel spiked well above gasoline. That price increase, combined with the huge drop in car sales over the past 12 months, has caused most of the non-German automakers planning US market diesels to seriously reconsider or cancel there plans altogether. That's a shame, because if this engine is anywhere near is as good as some of the others we driven, Americans would probably love it.
The diesel V6 is a joint project between Nissan and Renault, with both companies contributing half of the development cost. It's got all the latest diesel goodies including a 23,000 psi common rail injection system, EGR and a particulate filter to eliminate soot. About three-quarters of the total production will be used by Nissan, largely for Euro market Infinitis like the FX and G series, while Renault will install most of its share in the new Laguna coupe. If the 235 hp/331 lb-ft diesel does make into the US Maxima, it will probably get EPA numbers in the range of 25/35 mpg city/highway. Hit the jump to check out a video tour of the engine.
