Thanks to Dale Earnhardt Jr., NASCAR and Hendrick Motorsports for hosting me at the Charlotte Motor Speedway in North Carolina.
I learned a lot about the engineering that goes into these cars. Each engine is designed to run at 9,000 RPMs for 700 miles in a single race, and then it's done. The drivers get close to an average of 200mph during these races, and that's a bit faster than I go in my GTI!
