UK Mugen distributor Race Prep Longshaw Distribution, has CAD images of the latest Mugen buggy, the MBX6. According to the text on the site that describes the visible features on the car from the pictures, the first noticable thing is that shock absorber suspension cups are very deep to ensure the spring stays in place. Its a completely new car with what looks to have hardened aluminium parts throughout such as the main chassis, shock bodies etc. as well as what appears to be lightened diff-outdrive cups. The front drive shafts use a captured drive pin inside the bearing, and if you look closely at pic 3 below you can see the small grub screw which will allow you to tighten the drive shaft cup without pulling the whole drive train apart. In the final picture below, you can see that the anti-roll bar mounts are angled for easier tuning from the side of the car and for protection of the rear end parts, and to help keep unsprung weight down, the car is supplied with rear mud guards.
