Twin'Run sits on a multi-tube high-performance steel chassis derived from aeronautics and used in competition. The chassis was developed entirely by Tork Engineering. The ground link is provided by front and rear axles fitted with double-wishbone suspension with independent pivots. The four pivots, in solid aeronautical quality aluminum, deliver high performance on the track. For filtering and body stability, Twin'Run is fitted with OHLINS spring shock absorbers at the front and rear.

The axles have an anti-roll bar with a diameter of 22 mm at the front and 25 mm at the rear. Roll is perfectly controlled for agility and responsiveness.

The aluminum wheel covers feature a special hub with a central bolt that can be dismounted in three parts and fit 18" Michelin tyres.

Rally champion Jean Ragnotti was involved in the final tuning of the chassis system of Twin'Run. He shared his impressions with us while taking a look back at the R5.

"Following this first drive, I'd say that this is a sound car with a strong pedigree. It's easy to control. You can feel straight away that it's a sports car. In terms of balance and ride, it brings the R5 Turbo to mind to some extent.

The gearbox is smooth and you've got powerful brakes. Excellent traction with a responsive engine delivering full power at all revs, rounder and with more torque than the R5 Turbo, making it particularly efficient and easy to drive, unlike the R5, which required more technique.

It's definitely an efficient car with surprisingly good vertical comfort, including in zones of high compression where we're still a long way from the travel stops. All we need to sharpen our attacking edge a bit more are racing tyres. There's a slight roll but no understeer. A gradual performance, no surprises, taking corners easily. This concept car is a worthy heir to the Maxi 5 Turbo."
