Recently, the idea came to flower at Superlite of running a diesel Superlite SLC on a coast-to-coast run, on a single tank of fuel.This was mentioned in passing to the owner of a Biodiesel company, the response was immediate...Lets do it together. 

And now, the result of that idea is the first diesel- powered SLC. The car is basically a stock SLC with a very efficient 2009 VW 2.0l 4-cylinder TDi engine. Using pretty tall gears from a European- market VW TDI car for economy, the engine and transaxle slotted right into the SLC’s engine bay with only a few modifications to accommodate the taller inline powerplant. With a larger fuel capacity, the SLC is primed to make the cross-country jaunt this fall, when the weather is right, and the logistics are set.
