Dartmouth Formula Racing (DFR), a student-run organization, designs and manufactures formula-style racecars and produces outstanding leaders and engineers in the process.
The 2007 DFR car was designed and built by four teams of students who initiated their design process in the ENGS 190/290 design sequence.

The 2007 Dartmouth Formula Racing (DFR) vehicle dynamics and dampers team completed all design and manufacturing for the vehicle. The final system is composed of four sections: the front sliding bellcrank, the anti-roll package, the rear bellcrank, and the anti-roll package. Our sponsors required us to develop a highly adjustable vehicle dynamics package in which bump and roll movements are decoupled. In the front, a sliding-bellcrank system was selected primarily for its ability to separate and manage independently these bump and roll forces. In the rear, a counter-acting spring system was selected due to packaging constraints.
The 2007 Dartmouth Society of Engineers Prize was awarded to Henning Olson, David Manegold, and Staffan Skallenas for outstanding performance in their B.E. project.

This year's Dartmouth Formula Racing (DFR) differential drivetrain and braking team was responsible for building systems capable of effectively delivering engine and braking torque to the road for the DFR vehicle. Through the design process, it became apparent that the drivetrain was limited by its mechanical components. While exceeding the specifications from last year's car, the team felt that through an electronic system, mechanical limitations could be overcome. This system allowed the DFR car to corner and accelerate well past its previous limits. Our sponsor, Taylor Race Engineering, allowed the team to modify their existing differential design in order to make improvements in weight reduction and performance.

Dartmouth Formula Racing (DFR) has traditionally been successful with vehicle design for the annual FSAE© competition. To further enhance the performance of its competition vehicles, the race electronics team aimed to develop an advanced electronics package. The team developed a traction-control system and driver display for the 2007 vehicle.
Groundwork was laid for an electronically-controlled wastegate system. To complete this project, the team mastered engineering principles in automotive electronics, instrumentation, data acquisition, and microcontroller programming.

The structural composites group's goal was to investigate the possible integration of composite materials into the 2007 Dartmouth Formula Racing (DFR) E85 racecar. The group decided to design and build the suspension and seat from carbon fiber. Through rigorous testing, the group optimized the process of carbon fiber construction. By using carbon fiber, the team was able to decrease the weight of the suspension system, while increasing the stiffness. The weight of the seat was also decreased, while the overall rigidity of the car was improved. A study was also performed on the feasibility of using carbon fiber half-shafts, which will provide valuable information for future DFR teams.
