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. 

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.

Sportsman Stock Cars

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.

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".

SuperModifieds

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. 

Midgets

Only slightly smaller than a sprint car these 4 cylinder machines are one of the purest forms of racing. Since midgets run without a wing these race cars will "wow" the crowd with their slicing and dicing action. Midgets have a deep and rich history in Colorado.

Mini Sprints

Mini sprints are just slightly smaller than a midget but no less exciting. Mini sprints run on both dirt and pavement and are one of the fastest growing divisions  around the country.

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.

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. 

Trains

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.

Busses

Get an old School Bus, put in a roll cage and hit the track...... These super sized, 6 wheel racers hit the "Figure 8 - X - " and race window to window
