Is Porsche's New Le Mans Racer Diesel Powered?

Porsche has been doing a slow strip tease of its new Le Mans challenger for what seems like ages now. This time, they're showing off engine development. And if my eyes aren't deceiving me, this could very well be a diesel Porsche race car.


Around 46 seconds into the video, a close up of the cam covers on the race car shows four letters: TDFI. Now, that could mean two things. Turbo diesel fuel injection, or turbo direct fuel injection.

The earlier rumors for the Porsche engine centered on what configuration it would be. Some said V8, others called those people coocoobananas and said it was a flat six, and some band of heretics have said that it would be an inline four. While the engine layout hasn't been announced, what hasn't really been discussed is Porsche possibly going for diesel fuel.

Would a diesel Porsche LMP car be that much of a surprise? Not really. Le Mans has now been won by diesel cars every year since 2006. Gas cars have been given rules concessions and diesels have been given penalties to try and equal the fight in the last few years, yet they still have won. If they didn't at least consider a diesel, they'd be making a GOB Bluth level "huge mistake."

Does Porsche have a production car that runs on diesel? If the answer is no then this is MAJOR news. The argument for these factory LMP1 cars is that the technology trickles down into the production cars. A 911 Turbo Diesel? YES PLEASE.
