16:55 25/4/2013 - Πηγή: AutoBlog

Το μυστήριο πρωτότυπο της Renault εμπνευσμένο από τη Formula 1, είναι το Twizy Renault Sport F1 Concept. Ξεχωρίζει το άκρως επιθετικό bodykit βγαλμένο από την F1, αποτελούμενο από μπροστά αεροτομή, διαχύτη, πλαϊνά spoilers, πίσω μεγάλη αεροτομή, σλικ ελαστικά και

το σύστημα KERS.

Το πρωτότυπο είναι συνεργασία των μηχανικών της Renaultsport και της Renaultsport F1 οι οποίοι δούλεψαν μαζί, και εφαρμόσουν την τεχνολογία της Formula 1 σε ένα αυτοκίνητο δρόμου. Το σύστημα KERS προσθέτει 30 κιλά, με τις μπαταρίες να είναι τοποθετημένες στη θέση του πίσω καθίσματος.

Ο ηλεκτροκινητήρας του αποδίδει 17 άλογα με το σύστημα KERS να προσθέτει επιπλέον 79 άλογα. Συνολικά αποδίδει 97 άλογα με το Twizy να έχει τελική ταχύτητα 110 χλμ/ώρα. Ζυγίζει 564 κιλά, 91 περισσότερα από το απλό Twizy και έχει αναλογία 5,8 κιλών/ίππο, έναντι 1/25 κιλών/ίππο που έχει το απλό Twizy.

Στις σχετικές ειδήσεις η Renault ανακοίνωσε τα αποτελέσματα του πρώτου τριμήνου. Πούλησε 608.455 αυτοκίνητα (-4,7%), με τα έσοδα να μειώνονται κατά 11,8%, αφού αυτά ανήλθαν σε 8,26 δις ευρώ.

TWIZY RENAULT SPORT F1 CONCEPT: IMPROBABLE AND SPECTACULAR

Renault has chosen the Twizy manufacturing plant in Valladolid, Spain, to present its new Twizy Renault Sport F1 concept car. This fun take on the brand’s electric urban compact features muscular styling and impressive performance credentials to serve as a bridge between the world of F1 technology and that of production cars.

Twizy Renault Sport F1 sits on the wheels of a single-seater race car and is equipped with a front splitter, side-pods, rear wing and a diffuser complete with an F1-style rain light which forcefully express the concept’s ties with motor racing’s premier category.

Twizy Renault Sport F1 is much more than just a concept. In addition to its spectacular looks, it delivers genuine high performance thanks to its Kinetic Energy Recovery System (KERS) which is identical to the solution used by Renault-powered Formula 1 cars. The system instantly boosts power output six-fold to reach almost 100 horsepower and is capable of catapulting the car from standstill to 62 mph as quickly as Renault’s highest-performing road car, Mégane Renaultsport 265. This technological gem is the fruit of close collaboration between the engineers at Renaultsport and their colleagues at Renault Sport F1.

This extraordinary vehicle showcases Renault’s advanced expertise in electric technology employed in F1, notably in the field of KERS in which it was one of the precursors in 2009. Renault’s long-standing commitment to motor racing’s blue ribband category provides it with a unique technological laboratory, giving it an advantage not only in the world of race cars, but also in that of road cars.

Twizy Renault Sport F1 will be shown at major events throughout the year, beginning with its first public appearances at the World Series by Renault meeting at Aragon, Spain (April 27-28), followed by the Barcelona Motor Show.

I. F1 TECHNOLOGY APPLIED TO TWIZY

“We always said we wanted to create F1-derived technology that was road relevant! Hopefully, this Twizy will make a few people smile while also making a serious point. The project was led by Renault Sport F1 and Renault Sport Technologies, working in close conjunction with Renault’s electric vehicle development department. KERS is a very complex system and integrating it into another electric vehicle was a very serious endeavour, but they managed to make it work, delivering a huge boost of power safely and efficiently. I’m not sure we’ll be seeing many of these on our roads, but it does show that the same principles we see on the race track can be filtered down to the road legal range – this is just the evil elder brother!”

Jean-Michel Jalinier (President and Managing Director, Renault Sport F1)

1. Small but tough: a spectacular look inspired by Formula 1

Twizy Renault Sport F1’s calling is immediately apparent through its slick tyres (the same as those fitted to the Formula Renault 2.0 single-seater), as well as through its carbon splitter, side-pods and rear wing. Its unique proportions give it the appearance of a beast that is about to pounce yet which is still fun to drive.

Other features derived from the racing world are its single-seater type mirrors and diffuser, which incorporates the rain light of a Formula Renault 3.5 car. At the same time, the bulbs of the lights have been replaced by LEDs which, again mirroring the world of motor sport, consume less energy.

Meanwhile, Twizy’s rear seat has made way for the KERS which is visible inside a transparent housing. Last but not least, Twizy Renault Sport F1 is equipped with an F1-type steering wheel from the Renault Sport Technologies catalogue.

“Twizy Renault Sport F1 is a simple, yet smart, vehicle which combines original lines and advanced technology derived directly from Formula 1. Our objective was to reinforce Twizy’s ‘fun’ side by using F1 cues to express its personality. In terms of both its look and performance, the result is quite simply spectacular.”

Eric Diemert (Design Director, Renault Sport Range).

In order to express the link with Formula 1 and the Renault Sport race car range, both Renault Sport F1 and Renault Sport Technologies contributed to Twizy Renault Sport F1’s design.

“As far as styling was concerned, we wanted to avoid falling into the trap of simply producing a steroid-fed Twizy. We therefore worked closely with Renault Design to find a way of incorporating Formula 1 cues on a vehicle of this size. Although Twizy’s forms clearly distinguish it from a single-seater race car, you can see numerous echoes of the world of grand prix racing.”

Tarik Ait Said (Project Coordinator, Twizy Renault Sport F1).

2. A Twizy boosted by F1-derived technology

Twizy Renault Sport F1’s performance credentials are founded on the use of the KERS employed by Renault-powered Formula 1 cars.

The KERS (Kinetic Energy Recovery System) is designed to recover some of the kinetic energy which is generated under braking. Instead of being lost in the form of heat, this energy is recovered and stored before being used to momentarily boost power output, just as it is in Formula 1.

The KERS comprises three main elements:

- An electric motor-generator unit (MGU) directly linked to the driveshaft.

- Specific lithium-ion batteries.

- A KERS Control Unit (KCU).
