Η Peugeot εισήγαγε πρόσφατα την αγωνιστική έκδοση του RCZ. Το αυτοκίνητο αυτό θα λάβει μέρος στο ενιαίο πρωτάθλημα RCZ Racing Cup το 2012. Οι μετατροπές δεν είναι πάρα πολλές και δεν θα διαφέρει σε πολύ με το αυτοκίνητο που υπάρχει στις εκθέσεις. Οι τροποποιήσεις εκτείνονται στον υπερτροφοδοτούμενος κινητήρα THP των 1.6-λίτρων, ο οποίος έχει λάβει την απαραίτητη μεταχείριση από την Magneti Marelli και τώρα αποδίδει 50 επιπλέον ίππους, φτάνοντας συνολικά ο οδηγός να έχει στη διάθεση του 250 άλογα, ενώ η ροπή βρίσκεται στα 290Nm. To μοτέρ συνδυάζεται με ένα σειριακό κιβώτιο με paddles αλλαγής στο τιμόνι.
Επίσης φοράει νέα αγωνιστική ανάρτηση αλλά και σύστημα πέδησης το οποίο προέρχεται από AP Racing. Οι υπόλοιπες αλλαγές είναι οι κλασικές που έχει ένα αγωνιστικό αυτοκίνητο για την αύξηση της παθητικής ασφαλείας, με roll-cage, ζώνες πολλαπλών σημείων, bucket κάθισμα κλπ. Η συνολική μείωση του βάρος ανέρχεται στο εντυπωσιακό νούμερο των 250 kg.
Ο Frederic Bertrand, επικεφαλής του τμήματος πελατών στο Peugeot Sport δήλωσε
“Θέλαμε να κάνουμε ένα “πραγματικό” αγωνιστικό αυτοκίνητο που θα προορίζεται για πελάτες-οδηγούς όλων των ηλικιών, από όλα τα κοινωνικά στρώματα, είναι στην πραγματικότητα αγωνιστικό αυτοκίνητο “χωρίς όριο”.
Η συμμετοχή σε 7 αγώνες θα κοστίζει €54.900.

RCZ PEUGEOT SPORT
THE NEW FACE OF MOTOR RACING
THE CONCEPT: PACKED WITH PEUGEOT SPORT EXPERTISE
The production of a ‘premium’ customer-competition car for saloon racing is something new at Peugeot and stemmed from the launch of the RCZ. The combination of this model’s sculptural, innovative styling and its 1.6 THP engine provided a first class base for the development of a high-end racing version.
To ensure total coherence with the production version, the RCZ Peugeot Sport retains the original’s styling hallmarks, from its bonnet and double-bubble roofline to the polished aluminium arches which contribute to the car’s contemporary, sporting stance. In addition, the race version stands out through bespoke features such as the adjustable rear wing, exterior mirrors and cockpit-cooling roof vent.
Engineering work on the RCZ Peugeot Sport began in spring 2010 and the car turned a wheel for the first time at Satory in August the same year. To optimise performance and reliability, the car will not make its competition debut until the start of 2012 following an intensive development programme which included wind-tunnel work and running at seven different circuits. Indeed, a single RCZ Peugeot Sport clocked up more than 8,000km at circuits of varying profiles, from the abrasive asphalt of Dijon and the technically-demanding corners of Val de Vienne, in France, to the heat of Circuito de Navarra, Spain, while the different test drivers had complementary driving styles.
COCKPIT: EXTREMELY PAMPERED DRIVERS
In addition to the RCZ Peugeot Sport’s technical credentials, its drivers have been particularly pampered, too. Strapped into their HANS®-compatible bucket seat thanks to six-point harness belts, they can easily access the centre console which houses the different controls and the rear brake pressure regulator. Meanwhile, the perfectly visible colour screen displays all the information needed for precise, efficient driving.
On the track, the first thing that impresses about the car is the smooth, linear acceleration ensured by its 250hp 1.6 THP engine which delivers peak torque of 290Nm. High torque is available from the very low revs to provide powerful re-acceleration out of the tightest turns.
The steering wheel-mounted gearshift paddles permit ultra-quick gear changes, while the electronic gearshift control system means that drivers do not need to use the clutch.
The RCZ Peugeot Sport’s cornering performance is equally impressive thanks to its nicely balanced chassis and efficient, reassuring handling. The absence of a brake servo allows drivers to profit fully from the stopping power of its 355mm-diameter front discs and six-pot callipers.
Ambitious racers and gentleman drivers alike will appreciate how reassuringly easy it is for them to familiarise themselves with the RCZ Peugeot Sport which allows a sufficiently broad spectrum of set-up possibilities to suit all driving styles.
A CAREFULLY-ENGINEERED TECHNICAL PACKAGE
The RCZ Peugeot Sport is based on the production version, the monocoque body shell of which has been fitted with a welded roll-cage for driver safety and to rigidify the chassis. The bonnet conceals a tuned 1.6 THP which features an optimised air intake system, a new turbocharger and specific conrods and pistons. It drives through a race-developed six-speed sequential gearbox. The majority of the suspension parts are carried over from the production version, while the dampers are made specifically by Peugeot Sport. In addition to ensuring low running costs, this mix of production parts and specific racing components guarantees an outstanding trade-off between performance and reliability.
Engine, gearbox and electronic management
The transversally mounted, four-cylinder, 1,600cc EP6CDTm block employs specific racing pistons and conrods. Other parts, like the crankshaft, flywheel, camshafts and valves, are standard, as are the cylinder head and throttle butterfly. Air is fed to the specific air box via a scoop located in the centre of the grille, while the Borg Warner turbocharger is cooled by the original intercooler which has been fitted above the bespoke water radiator. The production exhaust manifold has been extended by a 70mm-diameter line in order to achieve a flattering engine pitch. All engines are run-in, sealed and bench-tested before going in the cars.
The Sadev-developed sequential six-speed gearbox incorporates a limited slip differential. Two steering wheel-mounted paddles activate the hydraulic gear selector for extremely fast gearshifts and outstanding long-term reliability.
The electronic management system uses a Magneti-Marelli SRT unit which comes with a chassis and engine data-logging system. The specific wiring loom is controlled by a centre console-mounted power box which incorporates all the controls. The RCZ Peugeot Sport is delivered complete with Wintax data analysis software.
Chassis, suspension and running gear
All soundproofing has been removed, and the steel monocoque body shell is fitted with a welded roll-cage – with links notably to the upper suspension mountings – for enhanced driver safety and to rigidify the chassis. The shell itself has also been modified to accommodate three quick-lift hoists and the adjustable rear wing pylon.
The MacPherson-type front suspension arrangement complete with anti-roll bar is chiefly based on production components, while the Peugeot Sport-developed dampers permit a range of settings (ride height, camber, toe). The original steering rack has been modified and the car is equipped with power steering. At the rear, the original trailing arms attach to a flexible beam, while the spring/damper assemblies are also specific for competition use. RCZ Peugeot Sport sits on hard-compound 25-64R18 slicks fitted to one-piece wheels.
Work aimed at lightening the chassis has resulted in a kerb weight for the RCZ Peugeot Sport of just 1,070kg, a saving of 250kg over the production version of the car.
The RCZ Peugeot Sport’s durable, precise, high-performance braking is one of the principal contributors to the car’s active safety, and the absence of a servo favours precise, consistent feedback from the pedal. The vented 355mmx28mm front discs are equipped with six-piston callipers, while the solid 290mmx12mm rear discs are the same as those fitted to the production RCZ. The front/rear brake bias can be adjusted thanks to a proportioning valve which acts on the rear brakes to prevent the car’s wheels from locking under heavy braking.
In addition to the crumple-zone structures which are a feature of the production model, the RCZ Peugeot Sport comes with the necessary passive safety equipment required for circuit racing, including a multipoint welded roll-cage, a HANS®-compatible bucket seat, a six-point harness belt, a fire extinguisher and a battery cut-off switch.
