Standard chassis: efficiency and comfort
The development of the standard chassis from the Clio Renaultsport 197 was guided by a bid to strike the best possible balance between performance and comfort when driven daily. Clio Renaultsport 200 marks an improvement in terms of comfort over its predecessor thanks to:
•new damper settings (15 per cent softer),
•the use of hydraulic double-effect dampers. The energy which needs to be dissipated is absorbed in part by an additional level of valving. The performance of these new dampers is particularly appreciable on longer journeys and motorway drives.
Meanwhile, body movement is kept in check thanks to the larger diameter front anti-roll bar, up from 20mm to 21mm. Specifically-developed Continental Sport Contact 3 tyres (215/45 R17) ensure swifter, more precise steering response. The new design of the standard aluminium alloy wheels is now 1kg lighter and the ensuing gain in terms of unsprung weight contributes further to the new car’s enhanced steering response and crisp acceleration.
The ‘Cup’ chassis: glued to the road
New Clio Renaultsport 200 is also available with the Cup chassis which has been engineered to deliver an exacting ride and uncompromising driving enjoyment. Its ability to corner flat is enhanced by:
•uprated dampers (15 per cent stiffer) compared with the Cup setting on Clio Renaultsport 197
•stiffer springs compared with the standard chassis (uprated 27 per cent at the front and 30 per cent at the rear) for even better handling
The ride height remains 7mm lower than that of the standard chassis and the resulting lower centre of gravity ensures improved cornering performance thanks to reduced weight transfer. Torsional rigidity has been improved by 10 per cent enabling the potential of the independent steering axis front suspension to be fully exploited.
Last but not least, the Cup chassis now comes with a higher ratio steering rack (7.5% quicker than the standard chassis) which, combined with other specific development work, favours feedback to the driver in conditions of varying grip.
