GOODWOOD, England - The RCZ R, a super-performance version of Peugeot's Sports Coupe, will be unveiled at the Festival of Speed here ahead of its official launch at the 2013 Frankfurt auto show in September.The RCZ-R will make its debut at the 2013 Johannesburg International Motor Show to go on sale in SA in 2014.Its new THP engine produces about 200kW/330Nm from 1.6 litres with CO2 emissions rated at only 145g/km - what Peugeot calls "performance and unprecedented efficiency" - and drives through a Torsen differential "which promises grip efficiency and dynamic sensations at a very high level".Image galleryXavier Peugeot, Peugeot's product director, told Wheels24: "All the strength of style of the RCZ is enhanced by the very dynamic performance and the 200kW of this R version - which will delight sports car enthusiasts."'MOST POWERFUL YET'Bruno Famin, Peugeot sport director, added: "The sporting success of the RCZ Peugeot Sport developed for racing and the passion it arouses could not remain unanswered. A series developed by Peugeot Sport to be even sportier and with the performance of the new version of the RCZ was an obvious step!" Xavier Nicolas, RCZ product manager, admitted: "Our brief was ambitious; develop a top-specification, high-performance version of the RCZ, preserving the qualities of comfort and convenience for everyday use, all with low fuel consumption and CO2 emissions."Peugeot says the RCZ R "is the most powerful production model in our long and illustrious history". It accelerates to 100km/h in less than six seconds with only 145g/km (of CO2 emissions) which leads the sports coupe segment. This is achieved by using the downsizing capacity of the engine, saving weight and ensuring aerodynamic optimisation."FIXED SPOILERTechnical manager Cyrille Jourdan explained: "Downsizing is a logical approach and not only in production vehicles; it's also happening at the forefront of motorsport, with the major disciplines soon to use a turbocharged 1.6-litre, even Formula 1 in 2014!" Aerodynamics have increased rear downforce with a new fixed boot spoiler which promotes stability at high speeds without increasing drag.Black roof arches distinguish and adorn the RCZ R. Its suspension is lowered by 10mm and the two-tone diamond / black matt alloy rims are 19" to optimise grip, give the RCZ R an expressive posture and were tooled to accommodate and optimise cooling of larger brakes whose red front calipers are signed Peugeot Sport."A specific rear diffuser." Peugeot says, "meets the smooth effect that characterises the tail of the RCZ and includes the two chromed exhaust pipes that end a re-worked exhaust system for performance and sound. A red Peugeot ‘R’ is on the grille and, on the boot lid, as a signature ‘RCZ R’."The 'R'-branded Nappa leather and black Alcantara seats are of a new sports design; a centre-console chromed plate confirms the character with a red inscribed ‘R’ emerging from a brushed aluminiuim certification plate.THINK SAVING FUELThe nature of the RCZ R shows in its performance figures: 250km/h, 5.9sec to 100km/h, standing kilometre 25.4sec, 6.8sec from 80-130km in sixth gear.The RCZ R was developed by Peugeot Sport not only as a racing version for track use but also to be durable in road-going applications, docile and responsive for everyday road use with comfort levels set by the similar RCZ 1.6-litre THP 200.And for the thinking buyer: 5.81 litres/100km (Euro combined test cycle).The THP engine was awarded the 2013 International Engine of the Year (1.4-1.8-litre category), its seventh win in a row.
