Η Volkswagen από πέρσι είχε ανακοινώσει το Polo R WRC Street, της έκδοσης δρόμου του αγωνιστικού Polo R WRC, με τη παραγωγή του να περιορίζεται στις 2.500 μονάδες.
Ο βελτιωτικός οίκος B&B όμως θεώρησε ότι ο 2,0-λιτρος TSI κινητήρας με τα 220 άλογα και 350 Nm ροπής δεν ήταν αρκετά και έτσι με το Stage 3 κιτ βελτίωσης του αυτός αποδίδει 362 άλογα και 510 Nm ροπής!!.
Το κιτ κοστίζει €7.950 και η αύξηση αυτή οφείλεται στην τοποθέτηση νέας αντλίας καυσίμου, νέου συστήματος εισαγωγής αέρα, νέα ολόσωμη εξάτμιση, μεγαλύτερο intercooler, αναβαθμισμένο σύστημα λίπανσης και νέο εγκέφαλο.
Πλέον τα 0-100 χλμ/ώρα από 6,4 δευτ., τα κάνει σε 5,2 δευτ., τα 0-200 σε 17,1 δευτ., ενώ η τελική ταχύτητα έχει αυξηθεί από τα 243 χλμ/ώρα στα 270 χλμ/ώρα, με την κίνηση να μεταφέρεται στους εμπρός τροχούς μέσω ενός 6-τάχυτου μηχανικού κιβωτίου.
Οι αλλαγές συνεχίζονται στο στήσιμο του αυτοκινήτου, όπου πατάει πάνω σε 18άρες ζάντες της B&B με ελαστικά 225/35, ενώ φοράει coilover αμορτισέρ, πιο σκληρά ελατήρια και μεγαλύτερα φρένα με δαγκάνες τεσσάρων ή έξι πιστονιών.

It got off to a good start: Already in its first FIA World Rally Championship season, the Volkswagen Motorsport team with the Frenchman Sébastien Ogier did not only set the drivers’ world champion but also secured the brand name World Champion of the WRC. To match the success of the rally bolides Volkswagen has also sent their “civilian“ brother the “Polo R WRC Street” to the streets during the past few weeks. The experts of B&B Automobiltechnik from Siegen, who have specialized in optimizing VW and Audi vehicles since over 29 years have now taken on the task of technically and optically reworking this special high-performance model that is limited to just 2,500 vehicles in production.
B&B Automobiltechnik has thus boosted the power in several stages from 220 horse power and 350 Nm to up to 362 horse power and 510 Nm torque. Acceleration time from 0 to 100 k.p.h. drops in the strongest upgrade stage, from 6.4 to 5.2 seconds and the 0-200 k.p.h. value drops from 24.2 seconds in the standard production version even down to 17.1 seconds in stage 3. Maximum speed increases from 243 k.p.h. to 270 k.p.h.The power upgrade portfolio begins with stage 1K for € 1,198: Modification of the electronics (minimum increase in charging air pressure and adaptation of the electronic injection parameters) is sufficient to get the 2.0 TSI engine to 280 horse power and 420 Nm. Moreover, stage 1S (€ 1,498) entails the processing and optimization of the air guides and suction paths thus producing 310 horse power and 450 Nm. In stage 2 (326 horse power / 475 Nm / € 2,995), an enlarged and cross-section optimized special front exhaust pipe is installed, charging air pressure is increased by approximately 0.25 bar and the engine electronics adapted to such modifications.
Finally, for 362 horse power and 510 Nm torque, stage 3 entails a special high-pressure fuel pump and a modified air suction system and the company’s own sports exhaust system for the purpose of reducing exhaust counter-pressure and exhaust temperature. A high-performance charging air cooler and a special oil-cooling system ensure at all times that temperatures are well within the proper range. Adaptations are subsequently made in the area of suction and engine management. The price of the big performance stage is € 7,950. The front exhaust pipe in stage 2 can also be obtained separately and generates an additional performance capacity of approximately 16 horse power. Sports rear silencers, sports exhaust systems as from the catalytic converter version or complete racing exhaust systems including metal catalytic converter (+ 20 horse power) can also be obtained “individually”.
Moreover, B&B emphasizes that sportiveness and thriftiness as well as environmental consciousness must not mutually exclude each other: In the vehicle in the picture, B&B technicians installed a full-throttle-resistant auto-gas system, which can be used up until maximum torque – also with performance boost – thanks to its ingenious electronic control system. The alternative usage of the SuperPlus in fuel operation remains possible at all times. To optimize the handling characteristics and the visual appearance of the Polo R WRC Street, B&B optionally offers a 20/30 millimeter set of sports springs (as from €248) and a B&B coilover kit that is specially adapted to VW Polo R WRC Street and is height, compression and rebound-adjustable (as from € 1,798). There are also optional B&B stabilizers for front axle and rear axle for even more driving stability and minimum roll behavior in cornering (as from € 498). Adequate deceleration for the significantly boosted driving performance is guaranteed by a special 4 or 6-piston high-performance braking system, which tends to fill the pilot of the Polo R WRC Street at all times, with a sense of outstanding safety. Weight-optimized rims in 8×18 inches with tires of size 225/35R18 successfully round up the exterior of the ”Racing Polo”. To bring the visual appearance of the street model even closer to that of its bigger racing brother, an eccentric aerodynamic package in the visual appearance of WRC Racing is also in the offing.
