Ringbrothers Enyo - Why does it have a Torque Tube & Rear Axle Transmission?

Enyo Torque Tube Design - Ahlman Engineering

The Ringbrothers wanted Enyo to steer, ride and handle as great as she looks. Scott Ahlman, of Ahlman Engineering, specified a C6 torque tube architecture with the transmission bolted to the housed Dana limited slip differential at the rear axle for this front engine car. Ringbrothers left the torque to exposed and wrapped it with carbon fiber as shown here. Gorgeous.

Ahlman chose this driveline design because it gets significant weight to the rear. In addition to pushing the transmission to the rear with this design it also allowed the team to move the 1000 HP engine back a lot more than usual due to the lack of a transmission in the footwell. Finally, Gary Ragle's design had the front wheels pushed forward to help Enyo's rear weight bias further.

These three main architecture elements resulted in 46% front/54% rear weight matching the tire proportions front to rear perfectly for performance and connection to the car. As a result, Ahlman knew Enyo was destined to carve corners with great power down for acceleration and incredible braking even before he led the chassis and suspension design.
