Racing Divisions at CNS

Super Late Models
Cars in the Late Model division have a highly sophisticated racing chassis and a powerful V-8 engine. Their fiberglass and aluminum bodies closely resemble a Chevrolet Monte Carlo, Dodge Charger, or a short list of other American-made cars. These are the fastest machines that compete regularly at the speedway, with all Late Model drivers eligible for points in the NASCAR Whelen All-American Series, both in the Northwest Region as well as nationally.

Pro Trucks
The ProTrucks feature aftermarket-bodied replicas of full-size modern pick-ups. They have a pure racing chassis similar to a Late Model, but with a longer wheelbase. V-8 engines are used, with more limitations than in a Late Model.

Late Models
Sportsman cars have a factory chassis – often from a mid 1970’s through mid ‘80’s Camaro or Firebird – and only a slightly modified engine. Aftermarket bodies are allowed, and many of these cars are nearly as detailed as a Late Model. The “S” alongside their number allows fans to quickly identify them as a Sportsman car.

Grand American Modifieds
The Grand American Modifieds run an engine similar to those in the ProTrucks, but they weigh considerably less. Even with their narrower tires, they are thus capable of nearly the same lap speeds. All chassis have a factory original front stub, and car bodies are handmade of aluminum or fiberglass to loosely represent a 1970 or newer American made compact cars.

Figure Eight Stock Cars
A Figure-Eight car runs under nearly all the same rules as a Sportsman, but the chassis are set up to turn both right and left on the Figure-Eight track. Figure-Eight racing is a crowd pleaser that provides daring thrills as the cars narrowly miss each other in the “X”.

Super Stocks
Super Stocks run under a strict set of rules that allow for only very few performance modifications, but with all safety devices added. These division are generally intended for novice and low-budget competitors.

Pure Stocks
The Pure Stock division is very similar to a Super Stock division except this class is reserved for beginner drivers.

Legends Car Series
Powered by 1200 cc motorcycle engines, Legends Series cars are 5/8 scale replicas of the famous NASCAR Modifieds that were driven by the early heroes of the sport.

Modified Coupes
Flashbacks of the old days at Lakeside speedway.. The Modified Coupes come in all shapes and sizes and represent many decades of racing in Colorado. Don’t let the looks fool you, these guys are serious racers.

The fastest cars that run at Colorado National Speedway. These purpose built asphalt racers sport 800+ horsepower alcohol powered engines, 24″ racing tires and giant wings. 13 second laps around the 3/8 mile CNS racing surface hitting speeds of 125 mph is a Sunday drive for these racers.

Trains consist of three cars chained together, and two drivers. The front car is the only one with an engine; the middle car is completely empty, and the third car is the only one with brakes. The Trains display their wild action on the Figure-8 track.

The DEMOX (Demo-cross) is a division that is a combination of a demolition derby and a motocross. The cars race in a circle through the infield dirt jumps and are allowed to make contact with each other during the race. This wild and wacky division is a crowd favorite.

Supermoto bikes race on a course design to challenge the rider on both the dirt in the infield and the blazing fast paved oval at CNS.


Race Rental Modifieds
These equally prepared open wheel race cars can be rented and driven by fans who want to get a taste for auto racing. Each rental includes hot laps, qualifying, and a feature race. Call the track office for information about getting behind the wheel of a real race car.
