First, if you’ve never really been properly exposed to the Baja 1000, you absolutely need to see Dust to Glory. It’s a great watch.
Team EMW (East Meets West) from Greasecar Motorsports campaigns a classic beetle with a TDI engine that runs on veggie oil. Have a look at the great site they’ve got going.
I don’t follow off-road racing, but I wish them good luck. They seem to be doing just fine.
