<< Prev Page 2 of 2  Supervised by engineer Christophe Chapelain, Renaultsport R.S. 01 was designed in cooperation with benchmark technical partners.The carbon fibre monocoque was a natural choice in order to meet objectives in terms of weight and safety. Italy's Dallara was responsible for designing and building the chassis, in the same way as for Formula Renault 3.5. The tub, which includes the 150 litre fuel tank, features a steel roll cage at the top. At the front, a crash box absorbs energy in the event of frontal impact. Shaped like a boat's stem, the design contributes to aerodynamic efficiency. Another crash box attached to the gearbox, plays the same role at the rear of the car. The entire assembly respects FIA LMP1 2014 standards to ensure safety. Completing the list of safety features are a collapsible steering column, and a Sabelt bucket seat with a six-point harness, compatible with the HANS system. Grip is provided primarily by aerodynamic downforce and this is reflected in suspension design. In the same way as on sports prototypes, a conventional double wishbone layout has been adopted with pushrods and öhlins dampers. Adjustable for compression and rebound, the systems are positioned on either side of the body at the front, and longitudinally above the gearbox at the rear. The braking system combines 380 mm carbon discs from PFC Brakes with six-piston calipers. This choice is an excellent compromise between efficiency and endurance. Renaultsport R.S. 01 is also fitted with Bosch Motorsport ABS. The partner of Renault Sport Technologies for all its motorsport products, Michelin has developed special 18-inch tyres, mounted on wheels of original design with a central nut. The semi-stressed engine is bolted to the carbon monocoque on the distribution side, and to the roll cage at the top. Prepared by Nismo, the 3.8 litre V6 twin-turbo engine is derived from the Nissan GT-R. The main change in relation to the production model is the dry sump system intended to prevent oil surges during long corners. The Pectel electronic unit features a traction control function. Turbo pressure is set to deliver over 500 hp with maximum torque of more than 600 N.m. This positions Renaultsport R.S. 01 between a GT3 and a DTM in terms of performance. The Nismo engine is mated to a longitudinal seven-speed gearbox supplied by Sadev. With an eye to budget management, the same gear ratio sets will be used for all tracks. However, it will be possible to adjust the preload setting of the self-locking differential. Activated by steering-wheel paddles, the sequential control system is managed by an XAP electromagnetic actuator. Developed specially by ZF Race Engineering, the clutch features an anti-stall function and is designed for an extended service life. << Prev Page 2 of 2 |
