If you could create your very own, custom race track, what would it look like? What series would race there?
Mine would be a literal tri-oval racetrack; much like Pocono, but shorter, with more rounded straightaways and with higher banking. I would have the Nationwide and Cup Series race here, each with 1 event a year. There would also be a road-course included for IndyCar events. I chose to put this track in Savannah, Georgia, simply because of the location - the closest major tracks (Darlington, Atlanta, and Daytona) were each several hundred miles away.
(Now, with the real feet measurements here I know I'm probably off on specifics, but I did it just to give you an idea of how big the straights are in relation to each other - bear with me.)
Savannah Motor Speedway
0.7-mile tri-oval (to run counter-clockwise)
Front Straight: Straight with no banking, 1,100 feet long and 40 feet wide
Turn 1: A gradual left-hander with 18 degrees banking, 55 feet wide
Second Straightaway: Slightly curved left with 7 degrees of banking, 800 feet long and 45 feet wide
Turn 2: A quick, sharp left-hander banked at 15 degrees, 50 feet wide
Back Straight: Curved left with 4 degrees of banking, 1,800 feet long and 60 feet wide
Turn 3: A slow, sharp left-hander with 15 degrees banking, 45 feet wide
1.6-mile road course (to run clockwise)
Front Straight: Slightly curved right with no banking, 2,300 feet long and 40-60 feet wide
Turn 1: A slow, sharp right-hander with 15 degrees banking, 45 feet wide
Back Straight: Curved right with 4 degrees of banking, 1,800 feet long and 60 feet wide
Turn 2: A quick, sharp right-hander banked at 15 degrees, 50 feet wide
Second Straightaway: Slightly curved right with 7 degrees of banking, 800 feet long and 45 feet wide
Carousel/Turns 5 & 6: Two fast left-hand arcs each banked at 18 degrees, 2,100 feet long and 40 feet wide
Chicane/Turns 7 & 8: Two slow, right hand turns banked at 0 degrees, and 35 feet wide
Esses/Turns 9, 10, and 11: A short span of 3 tight turns: right, left, and right; 40 feet wide
Chicane 2/Turns 12 & 13: Identical to Turns 7 & 8
Turn 14: A wide, fast, sweeping arc leading to the front straightaway, 60 feet wide
I modeled this track after a bike racing course I have made in my driveway, alas on a much smaller scale, obviously.
