Weight does not include driver and fuel.


Swift 016a

Chassis


The overall dimensions of the monocoque were enlarged relative to the previous design to accommodate a larger range of driver sizes. Although this change brought about a weight increase in comparison to the previous chassis it was accompanied by an increase in torsional stiffness.

Durability is another major consideration in the design of the car. Currently the car is not being campaigned on oval tracks, but knowing there is the possibility of returning to these venues, Swift designed the chassis based on experiences learned from racing the previous two Atlantic 'spec' cars on ovals. The chassis was not designed to the minimum possible weight but more to a level of durability. A number of major incidents that occurred during the first season of racing has shown this to be a prudent decision and has proven the strength of the chassis.

The Atlantic series is a training series not only for drivers, but also race engineers and race car technicians. The 016.a was designed with ease of maintenance as a major consideration.

The layout of the mechanical components in the chassis was conceived for ease of maintenance. The steering rack was moved from inside the monocoque to the forward face of the front bulkhead. The master cylinders are mounted on the pedal assembly enabling the pedal location to e adjusted without the need to resort to cutting or replacing the master cylinder pushrods. Access apertures were enlarged to allow easier access to the chassis interior.

The directive from Champ Car, for the car to be faster in all aspects (straight line, cornering, decreased lap time) would prove to be quite a challenge.

Initial calculations showed that although the new power plant provided a 25% increase in power over the engine previously used in the series, the maximum speed of the vehicle would only increase by approximately 12 MPH, assuming the drag of the vehicle remained the same. Since the new car was larger in several dimensions and with wings of greater chord and span, a drag increase was inevitable. 50% scale wind tunnel models of both the old (014.a) car and the new car were created. The model of the new vehicle being very much a 'work in process' as the design progressed.

Both models were evaluated in the Swift wind tunnel and the data received, analyzed and fed back to the group working on finalizing the design. The use of the Swift wind tunnel data in conjunction with lap simulation programs enabled a study to be made incorporating both the aerodynamic changes and the weight increase of the car. Using these tools enabled the Champ Car directive to be achieved.

The Swift 016.a represents an evolution of the successful 008.a and 014a. The Swift 016.a Formula Atlantic racing car is the culmination of a comprehensive customer review of the 008.a and an application of Swift's extensive knowledge of racecar design. Evolutionary in design, the Swift 016.a utilized the Swift wind tunnel to aerodynamically shape the chassis elements and new bodywork.

Application of the state-of-art principles in composite technology and component engineering has increased the durability and performance of the bodywork, driveline, steering, suspension, and cooling systems. Finally, a brand new Swift SG4 gearbox complements the improved chassis. Improvements to the Swift 016.a represent an advanced step and new standard in the evolution of the Atlantic Series chassis.

Costs were held down through such economies as making removable bodywork panels of glass fiber rather than carbon, and using the same airfoil for all three wing elements (two in the rear). But this is still a serious race machine; it comes with a Pi Research data and dash system, a no-lift-shift feature in the five-speed Hewland, a push-to-pass button and without traction control.

In keeping with Atlantic tradition, the new Swift has larger ground-effect tunnels than Champ cars. These and smaller wings should make for closer racing.

Engine


The new-generation Atlantics will be powered exclusively by a 300 hp, normally-aspirated version of Mazda's 2.3-liter four-cylinder MZR engine, developed by Cosworth Engineering.

The head and cam cover of the MZR is a structural, stressed member of the chassis. "It was quite a complicated procedure because they had to decide how they tied in the top cam cover to the rest of the engine," Bisco explained. "They worked on special cam caps, extended studs, so that when it was all pulled together it pulled down into the core of the head rather then being something that just bolted onto the top of the head. That had implications for tolerances on cam bearings and clearances around the outside and all kinds of stuff."

Adding an engine and tire-support package brings the basic buy-in to the 2006 ***8220;Yokohama Presents the Champ Car Atlantic Championship Powered by Mazda***8221; to $179,000.
