Originally posted by FantasticMrFox I've never got the appeal of car races. My dad loves his Formula 1 on Sundays, but all I see is cars going round and round in circles for hours, always along the same ideal line ...
Now, with a bit more action and a non-circular track I might actually enjoy races. Always liked the kind of stuff
Top Gear did
F1 is always a road or street circuit. Never ovals.
Indy Cars run a mix if oval, road and street circuits.
Sports cars always run road a street circuits.
Drag racing is always a straight line, point to point. Mostly 1/4 mile, but Top Fuel and Funny Car got cut back to 1/8 mile when Doug Kalitta was killed. Something about a car exceeding 300 miles an hour by half track that was just getting too risky.
Now after all that, consider stock car racing. Yes, most of the races are contested on ovals. Twice each year they do run at road courses, Sears Point in California and Watkins Glen in New York.
There is much more to racing on an oval than meets the eye. It isn't as simple as just hopping in and going for a ride. Each track is unique and presents challenges that must be overcome.
Superspeedways like Daytona and Talladega are fast. Before the days of restrictor plates cars were exceeding 250 miles an hour on the straights. Even with restrictor plates the cars run at around 200. Aerodynamics are critical, and to run fast a driver had to know how to work the draft. Get out of the draft and you go to the back of the pack. Also, at speed each driver runs a very narrow line between having enough traction to keep the car going in the right direction or spinning out of control. If you were to reach out and push the rear fender of a car next to you at speed you could make it spin out with very little effort. When exiting the track for fuel and tires a driver has to bring the car down from 200 to 45. Not an easy task. And it has to be done in as short a time possible, as every second counts.
On smaller tracks the cars are not restricted.
One and a half mile tracks are completely different from the Superspeedways. Each has its own character, and requires a completely different approach. Some can be run nearly wide open, and the cars do run very fast. Some are bumpy and chassis setups must account for conditions to keep the car/s hooked up and maintaining forward bite off the corners. Drafting and aerodynamics are still important.
The half mile tracks are also completely different.
Martinsville is referred to as a paper clip. Two long and flat straightaways paved with asphalt with no banking connected by two narrow and tight radius turns paved in concrete with 12 degree banking (nearly flat). Brakes are huge and the heat is difficult to control. Thermal coatings are applied to the wheels and calipers, heat shields and multiple fans with ducting are used, and even then it is not enough. The heat damages the bead of the tires, and can also affect the oil in the shock absorbers. Sometimes if a driver does not manage the brakes well the fluid boils and then the brakes fail.
Bristol is a bowl. All concrete, and steeply banked, the Cup cars are lapping in just under 15 seconds a lap. The World's Fastest Half Mile. The steep banking makes it a self cleaning track, meaning when a car spins it will wind up going to the inside rather than go up against the outside wall and stay there. The corners are banked at 20 to 30 degrees, the straights 10 to 12 degrees. Again, brakes are a challenge. Heat generated must be managed. Cars with 800hp have to be able to slow enough to get around the turns.
Then there are the tracks which are unique.
Darlington is 1.33 miles. Turns 1 and 2 are tighter radius with 25 degree banking, turns 3 and 4 are larger radius with 23 degree banking. The front straight is banked at 3 degrees and the back stretch banked at 2. When the track was built the owner of a pond nearby refused to relocate it, and this resulted in the different radius turns at each end. The track is tough to set a car up for and racing there results in many cars getting the "Darlington Stripe" (by race end most cars will have brushed the outside wall). Fastest lap is 26.705 sec. (184.145 mph), set be Aric Almirola, driving for Richard Petty in April 2014.
Phoenix Raceway is just over 1 mile, a trivial with (minimal) banking. Turns 1 and 2 are 10 to 11 degrees, the dogleg is also 10 to 11 degrees, turns 3 is 8 degrees, turn 4 is 8 to 9 degrees, the backstretch is 8 to 10 degrees and the front stretch has 3. When the Indy cars ran there a couple weeks ago they were running flat out all the way around. Helio Castro-Neves set a lap record of 19.0997 seconds driving for Roger Penske.
Pocono Raceway is a very unique oval, 2.5 miles with 3 turns and 3 straights. Turn 1 is banked at 14 degrees, turn 2 is 8 degrees, turn 3 is 3 degrees. Each turn was modeled for turns at different tracks. Because the straights are so long, and the turns so tight, the track drives more like a road course than an oval. It is also the only oval where racers shift rather than run in a given gear. In many ways it is driven like a road course.
Stock car racing has many things common to other types of racing. Pit stops must be accomplished as quickly as possible. Teams practice pit stops over and over. A 13 second stop to change 4 tires, add 22 gallons of fuel and make adjustments is about normal. Race strategies play out for each event. Crew chiefs keep copious notes for car setup at each track. Teams build highly specialized and developed cars for each track to fit the demands and unique requirements for each one.
Yep.
It may be a Sunday drive or a Saturday night out, but there is far more than simply riding around in circles.
