Budar Pierre, Project Manager RCZ R.The sporty nature of the RCZ R is reflected in its performance figures, with a maximum speed of 155mph (electronically limited), a 0 to 62mph (100km/h) achieved in 5.9 seconds, the 400m standing start in 14.2 seconds and 1000m in 25.4 seconds. The times are also very low from 50 to 70mph, which takes just 6.8 seconds in (6th) top gear. The low centre of gravity, aerodynamic performance, improved suspension settings (wider track, camber angle, wider rims of +0.5") and Goodyear Eagle F1 Asymmetric 235/40 R19 tyres optimise adhesion and ensure outstanding road holding. The suspension has a new specification of dampers, increased stiffness of springs and a stiffer anti-roll bar, that allows for great handling and agility. The Torsen differential enables the engine to be fully exploited with maximum torque from 1900rpm to give the RCZ R good braking and cornering stability, especially when tackling tight corners. The performance and agility of the RCZ R is the result of many sessions of development and validations on and off track, especially with Peugeot Sport's test drivers. Their requirement for excellent braking naturally oriented towards the technical specification of four-piston calipers, which allow a significant gain in stiffness and therefore pedal stroke, while reducing the unsprung masses. Discs with a diameter of 380mm and thickness of 32mm, are mounted on an aluminium hub. This contributes to the weight-saving and cooling performance, derived from the Alcon racing experience, to provide brake durability and outstanding performance, so braking from 80mph to zero requires less than 61 metres. "To get 270bhp and 330Nm of torque from a 1.6-litre engine and be resistant to sports use on the racetrack, it was necessary to introduce new high-performance, competitive solutions. Peugeot Sport has all the skills to do this. Research and Development teams brought together their experiences and expertise to ensure the sustainability of the car and its industrial application." Thierry Chauvet, Engine Development Manager for RCZ R. RCZ R is equipped with a new 1.6-litre THP turbo gasoline direct injection. It develops its maximum power of 199kW (270bhp) at 6000rpm and a maximum torque of 330Nm at 1900rpm to 5500 rpm. This new engine 'EP6CDTR' has been developed extensively, with many parts having evolved or been completely redeveloped for the performance requirement and to meet sporting use with the robustness of a competition engine. The engine itself is reinforced by a specific heat treatment prior to machining to improve durability. The twin-scroll turbo has been developed specifically to benefit from an ideal design for this application and this level of performance. Associated with a steel exhaust manifold with unique architecture inspired by racing systems, it can take higher temperatures. New pistons, providing a compression ratio of 9.2:1, were developed with Mahle Motorsport, taking a forged structure and a grade of aluminium used in Formula 1. Their cooling is provided by two jets. The con rods were specified to withstand continued use at high engine speeds. Their bearings are covered with a polymer coating that can withstand the higher cylinder pressures, patented in 2011 and presented by Mahle, they are premiered exclusively on RCZ R. RCZ R was developed as a racing version by Peugeot Sport to meet a sports track use, but also to be durable in road-going applications, so it is docile and responsive for everyday use on the road. Calibrations of the powertrain combine the requirements of a sporty driving style on the circuit and in daily use. In addition the level of torque obtained from very low engine speeds allows for a strong dynamic experience daily on the road. The suspension improves agility and is incisive for best handling but the RCZ R does not compromise the comfort levels set by the similar RCZ 1.6-litre THP 200. Finally, the finest materials and ergonomics of the driving position, its enhanced unique features and impressive economy - 44.8mpg on the Combined Drive Cycle - make the RCZ R a great performance car with comfort and convenience outside life on the race track. << Prev Page 3 of 3 |
