NASCAR FAQs
I'm new to NASCAR and am seeing a lot about how race mpg is around 4-5. Does anybody know if this has changed over time? I know that they switched from leaded to unleaded fuel in 2007 - wondering what it was like before that change. Thanks!

I suspect that it has been similar for many a year, but I will be happy to be corrected.
I bet the bigger change might have come when they went to fuel injection from carbs in 2012. |

It's barely fuel injection as we know it now. I think they have a similar setup my old Suburban had from the early 90s. It looks like a carb but is electronically controlled, and they still use restrictor plates at Daytona and Talladega instead of a tune. I've seen it reported they couldn't detune enough to make it worth it. Uses McLaren electronics, I'm guessing Lucas was not available for the contract.

Fuel mileage used to be dependent on how big your "tank" was:

Good ole Smokey, with all due respect to everyone thinking Penske reads the rules and knows every inch of the book, he knew EVERY rule and everything that wasn't banned
