Car of Tomorrow
From Wikipedia, the free encyclopedia
The Car of Tomorrow (CoT), occasionally called the "Car of Today",[1] is the current car style for the NASCAR Sprint Cup Series. The larger, boxier Car of Tomorrow boasts better safety, cost maintenance, and competition. It succeeds the older, rounded stock car design used in the NASCAR modern era.
The car was first implemented in the 2007 Cup season at the Food City 500 on March 25 and ran a partial schedule of 16 races. The original plan was to fully implement the car in 2009, but NASCAR officials made the decision to run the car full time in the 2008 season.

[edit] Design
On January 11, 2006, NASCAR announced a universal car named the "Car of Tomorrow" (or "CoT" for short) after a seven-year design program sparked mainly due to the death of Dale Earnhardt Sr., one of the sport's drivers, in a final lap crash during the 2001 Daytona 500.[2] The then-current cars were based on Holman Moody's 1966 Ford Fairlane.[3] The primary design considerations were "safety innovations, performance and competition, and cost efficiency for teams."[4]
The CoT has improved safety features over the older car.[2] The driver's seat has been moved four inches to the right, the roll cage has been shifted three inches to the rear, and the car is two inches taller and four inches wider.[2] Larger crumple zones are built into the car on both sides, ensuring even more protection. The splitter is a piece of fiber reinforced plastic (FRP) used on the bottom front of the car to produce downforce, replacing the valence. The car's exhaust runs through the body, and exits on the right side, which diverts heat away from the driver.[2] The fuel cell is stronger, and has a smaller capacity (17¾ gallons, down from 22 gallons, which as of 2007 has become standard in all cars).
The car is advertised as reducing dependence on aerodynamics. It features a detached wing, which has not been used since the Dodge Charger Daytona and Plymouth Superbird in 1970.[5] The windshield is more upright, which increases drag. The radiator air intake is below the front bumper of the car, which reduces overheating caused by clogged grills. The front bumper is more box-like, which catches more air and slows the car. The front airdam is gapped, as opposed to being a flush piece on the older cars.
All cars are required to fit the same set of templates, using a device that has been named "the claw" that is designed to fit over the new cars. In the first two races at Bristol and Martinsville Speedway, the garages were opened one day early and the inspections took up to ten hours so that everyone (teams, officials, etc.) could get a better grip on the new unified template. NASCAR's old rules had a different set of templates for each manufacturer (Ford, Chevy, Dodge, and Toyota). NASCAR has frequently adjusted the rules to ensure that different car manufacturers have relatively equal cars. The universal body of the CoT will eliminate these problems, but could cause many more unforeseen problems.

[edit] Testing
The Car of Tomorrow was first tested in December 2005 at Atlanta Motor Speedway. Next it tested at the 2.5 mile Daytona International Speedway, then on NASCAR's two shortest tracks, Bristol (0.533 mi) and Martinsville (0.526 mi.), the 1.5 mile Lowe's Motor Speedway, the 2.66 mile Talladega Superspeedway, and 2.0 mile Michigan International Speedway. Former NASCAR driver, current Sprint Cup pace car driver and Director of Cost Research Brett Bodine also tested the prototype car against cars prepared by current NASCAR teams.
Drivers have tested the CoT concurrently with the old car at some NASCAR tests and at special NASCAR-authorized tests. Some teams have tested the cars at the half-mile Greenville-Pickens Speedway, Caraway Speedway in Asheboro, NC, and the one mile North Carolina Speedway, none of which are Sprint Cup tracks, and therefore are tests which do not fall under NASCAR's restrictions.
[edit] Implementation
The Car of Tomorrow was first raced at the 2007 Food City 500 at Bristol, the season's fifth race. The tracks that saw the CoT twice in 2007 besides Bristol and Martinsville were Phoenix International Raceway, Richmond International Raceway, Dover International Speedway, and New Hampshire International Speedway. Other than Talladega (for the fall event), Darlington Raceway and the road course races at Infineon Raceway (Sonoma, Calif.) and Watkins Glen (N.Y.) International ran the CoT once each in 2007.
Original implementation plans called for the CoT to be used at 26 events in 2008, starting with both races at Daytona, including the season-opening Daytona 500 and related events (Budweiser Shootout and Gatorade Duels), the spring race at Talladega and Michigan, both races at California Speedway, Pocono Raceway and the event at Indianapolis Motor Speedway. Based on the success of the February 28th test at Bristol, NASCAR considered requiring CoT cars for the full schedule in 2008 in order to avoid applying two sets of rules (as supported by a survey of NASCAR owners, with 80% favoring the switch), adding all three events (including the all-star event) at Lowe's Motor Speedway, as well as both races at Atlanta and Texas Motor Speedway, and single races at Chicagoland Speedway, Kansas Speedway, Las Vegas Motor Speedway and Homestead-Miami Speedway one year earlier than scheduled.[2] This was confirmed on Tuesday, May 22, 2007 by NASCAR.[7] Had NASCAR continued with the original schedule of implication, the other tracks would have been added in 2009.
[edit] Debut
On March 25, 2007, the CoT debuted in its' first NASCAR-sanctioned race. Kyle Busch won the race, the first win by a Chevrolet Impala since 1963.
Reactions to the CoT's performance were mixed. Dale Earnhardt, Jr., after finishing 7th, said, "It wasn't a disaster like everybody anticipated. It worked out, I reckon. Racing was about the same."[8] Drivers were also impressed with the car's ability to bump other competitors without causing a spin (as bumper heights were equalized; as street car development continued, nose-to-rear bumper contact caused spins that pre-1988 cars would not cause), and NASCAR officials were pleased with the improvements in safety.
Several drivers and pundits expressed distaste for the car and what they perceived as a less exciting style of racing created by it. Kyle Busch, despite winning at Bristol, commented that "they suck" during his victory lane interview.[9] Retired driver and TV analyst Rusty Wallace stated on ESPN that the car created a boring, single-file racing environment with little of the passing, action, or crashing that has made NASCAR popular, though after NASCAR announced the COT would run the full schedule, he stated that it was "one of the best decisions NASCAR had ever made." Drivers who placed well at Bristol, Jeff Gordon and Jeff Burton, claimed that the car allowed the use of a second passing lane not usually present at Bristol.[8] For the most part, however, the racing was strung out and single-file with drivers tentative in trying to make passes.
A major problem with the car's initial race was its front splitter. The splitter is a piece of fiber reinforced plastic (FRP) used on the bottom front of the car to produce downforce. It replaces the valence. One car's splitter running into the tire of another car beside it sometimes punctured the second car's tire.[10] There were no problems with the splitter causing tire failure at the car's second race.
Another major problem has been that the foam used in the side of the car has caught fire, causing smoke in the cockpit. Kevin Harvick experienced this problem at the first CoT race at Martinsville costing him a good finish or possibly a win, and NASCAR decided to make modifications before the April 21 Subway Fresh Fit 500 in Avondale, Arizona.[11]
Another problem with the foam was that when the side door was ripped open, as Brian Vickers experienced at Watkins Glen, the foam would spill out, making a mess.
During the 2007 UAW-Ford 500, the CoT's first debut on a superspeedway track at Talladega, NASCAR assigned a 31/32 inch (24.6 mm) restrictor plate to allow the engines to run at around 8,800 RPMs due to the less aerodynamic design of the CoT. The previous generation car's engine would normally run around 7,000 RPMs with a ⅞ inch (22.2 mm) plate.[12] This was the most open restrictor plate to race at Talladega since 1988.[13] On February 24th, 2008, Casey Mears became the first driver to flip the CoT when he was hit in the rear by Sam Hornish Jr.
[edit] Car models
Chevrolet teams continued to use the Monte Carlo SS with their old cars while using the Impala SS with the CoT. Chevrolet discontinued the Monte Carlo brand and switched full time to the Impala starting in 2008. Dodge teams used the Charger with the old car while using the Avenger with the CoT; however, Dodge has stated that the Charger will be their 2008 CoT.[14] Ford used the Fusion while Toyota used the Camry, respectively, for both their old and CoT cars.
[edit] Criticisms
Criticisms of the CoT began with its first tests, with the magazine Speedway Illustrated noting the car's poor performance in traffic (February 2006 issue). The Winston-Salem Journal also noted extensive criticism of the project during 2006 testing, with drivers becoming more vocal by July 2007 and most fans rejecting the model, citing the falsity of many of its technical claims;[15] one angle of criticism was the differing philosophies of NASCAR officials Gary Nelson and John Darby, with Darby a particularly ardent supporter of the CoT based on a misreading of the sport's competition packages.[16] Jeff Gordon and Matt Kenseth were pointedly critical of the car's poor performance in traffic, with Gordon stating after the 2007 Lenox Industrial Tools 300, "I'd like to know who it was who said this car would reduce the aero push because I could have told you from when I first drove this car that it would be worse."[17] Kyle Busch, who won the very first race with the car at Bristol in 2007, proclaimed that the car "sucks" afterward and expanded on this criticism at Dover in 2008 in noting how the Cars Of Tomorrow was "hitting a wall of air" in the wake of a leading car, thus neutralizing ability to close up on leaders.[18]
