Sneak Peek: GM’s ALMS GT Challenger, The Corvette C6.R

  • Mike Kojima

Sneak Peak: GM’s ALMS GT Challenger, The Corvette C6.R
The suspension has fabricated arms with bearings instead of bushings and fabricated uprights with elaborate carbon brake ducts.  The swaybars are tubular type and high mounted with long links.

The suspension was quite interesting.  The suspension links and uprights were all unique, hand-fabricated bits using spherical bearings instead of bushings.  The shocks were especially intriguing.   Made by Penske, they did not resemble any Penske product we are familiar with.  They had multi wire mil spec connectors connected to mysterious bulges on the body near the lines going to the remote reservoirs, bulges which looked like they contained PWM solenoids.

The rear suspension links are all unique, hand-fabricated items and mount to locations on the transaxle we think.  We were not allowed to get close to this part of the car at all.  The hub is fabricated and more carbon clamshell ducting for the brakes is also visible.

Some of the juncture boxes and control units for what we believe is an active damping suspension system.

Here is one of the Penske shocks with an extra hydraulic line and a bulge for what we think is a PWM solenoid.  We were told this was a temp sensor but we feel, yeah right….  To us this looks like active damping possibly with ferro fluid or active control of the compression damping circuit.  Note the linear potentiometer for logging the wheel position or perhaps active feedback.

We think these were for active control of compression damping or perhaps some sort of ferro fluid control.  When we questioned the crew they had answers like “I don’t know if I can tell you” or “if the boss says I can tell you I will”.  When we asked the boss, he told us it was for datalogging shock fluid temp.  Yeah right, you don’t need so many wires for that!

IR sensors for logging tire temps in real time across the face of the tire!  Coolness!

Overall we were pretty impressed with the GT versions of the C6.R and are glad we got to share our brief look at them with you!

The Corvettes are some of the best engineered GT class machines on the track.
