Δουλειά της a-workx δεν έχουμε ξαναδεί. Είμαι και αυτή Γερμανική και έχε μεγάλη εμπειρία σε αγώνες ταχύτητας στα πρωταθλήματα FIA GT, Porsche Carrera Cup και ADAC GT Masters. Έτσι αποφάσισαν να παρουσιάσουν την BMW M3 460cs, μια βελτιωμένη Μ3 E92 που αποδίδει 460 άλογα, αφού στόχος του ήταν να περάσουν τα 450 άλογα της M3 GTS.
Μηχανικά ο 4.0-λιτρος V8 ατμοσφαιρικός φόρεσε νέους εκκεντροφόρους, carbon φιλτροκούτι με ελεύθερο φίλτρο αέρα και Akrapovic Evolution εξάτμιση τιτανίου, η οποία είναι κατά 24 κιλά ελαφρύτερη από την εργοστασιακή και φυσικά επαναπρογραμματίστηκε η ECU. Έτσι η ιπποδύναμη αυξήθηκε κατά 40 άλογα και για να την περνά στο δρόμο φόρεσε και μπλοκέ διαφορικό της Drexler.
Επίσης φόρεσε KW Clubsport αναρτήσεις και νέες ελαφριές ζάντες 19″ ATS Superlights (ζυγίζουν 15 κιλά λιγότερα από τις εργοστασιακές) με ελαστικά Michelin Pilot Sport Cup διαστάσεων 235/35 μπροστά και 265/30 πίσω.
Τα 0-100 χλμ/ώρα τα κάνει σε 4.1 δευτ (4.8 εργοσ. τιμή), τα 0-200 χλμ/ώρα σε 13.2 δευτ (15.7 εργοσ.τιμή) και στην μικρή διαδρομή του Hockenheim, γυρνά σε 1:11.9, 6 δευτερόλεπτα γρηγορότερα από την BMW M3 GTS.
Φυσικά φόρεσε και μεγάλα φρένα της MOV ‘IT CER με carbon κεραμικούς δίσκους 380 mm μπροστά και 380 mm πίσω με 6-πίστονες δαγκάνες μπροστά και 4-πίστονες πίσω. Και αν τα 460 άλογα δεν είναι αρκετά, σε λίγο καιρό ετοιμάζουν και μια δυνατότερη έκδοση που θα αποδίδει 600 άλογα με την προσθήκη κομπρέσορα.
The a-460cs workx M3 – The M3 Clubsport version
The Bavarian tuner a-workx is known for his decades of experience in motor sports. Whether FIA GT Championship, Porsche Carrera Cup, Mini Challenge and currently ADAC GT Masters, always gathered the troops around Weßlinger chief Niko Wieth valuable experiences that make setting up a customer’s vehicle, the difference with the rest of the industry. Specifically, it is the sound know-how in terms of chassis technology and overall coordination, which can have here in Europe more than a handful of specialists. a-workx deals mainly with Porsche and BMW M cars, they had shortly after the launch of the BMW M3 E92 presented a slightly optimized vehicle that it was time to strike. The lap time of the a-workx M3 could not even 130.000, – € beaten expensive M3 GTS.
Now Niko has again Wieth comprehensively with the M3 coupe employs. The intention was to develop a car for connoisseurs who want to have an M3 GTS level, perhaps even something more. The concept is based on three components: the intelligent reduction of the weight, especially on unsprung and rotating masses, a moderate, the overall concept of the vehicle right and not an exaggerated increase in performance, and a perfectly balanced and tuned suspension.
For these reasons, come on “M3 460 cs” only exclusive components used, which were extensively tested on various race tracks and on the street in everyday driving.
Among the details of the vehicle:
a-workx set to meet in increasing the braking performance of a MOV ‘IT CER ceramic brake system to the higher performance of the vehicle. The special here is the simultaneous reduction of rotating mass of the brake discs. This ultra-light, from the high-tech ceramic materials and finished 2-piece carbon discs allow the saving of 12kg rotating and unsprung mass. And this even at much larger dimensions (mm Ø380×40 forward Ø380×32 mm rear). With the combination of mono-block calipers (6-piston at the front axle, 4-piston at the rear) and braided steel brake lines and special racing brake fluid with higher boiling point, this brake system would be by no means overwhelmed even in racing.
To the constraints inherent unfavorable, as top-heavy weight distribution to wear on the M3 in combination with the resulting through the rear-wheel drive traction problems concern a-workx, together with the running gear specialist KW a chassis developed for the M3, which was tuned specifically to the special features of this vehicle. To this end weeks of testing work with professional racers and chassis engineers was necessary to Niko Wieth was ultimately happy with the outcome. The combination of ride height, the weight distribution on all four wheels (wheel loads), and camber values, the correct spring and damper rates as well as the precise adjustment of train and pressure stage is ultimately responsible to the maximum ground contact of the tire and thus the optimal traction and to achieve the best possible grip.
One can well imagine that such a delicate tuning of the chassis through the mounting of heavy wheels can be quickly reversed. Therefore be on the record-cs 460 M3 lightweight 19 “ATS Superlight with a weight of 7.9 kg (range 10.2 rim) tires.
Of course there is also the performance is not intact. The heart of the performance improvement is an Akrapovic Evolution exhaust system with special catalysts. This is manufactured from high-strength and super-light titanium, which has affected kg with a weight reduction of 25 extremely positive effect on the weight balance. Furthermore, special camshafts were installed, the intake air with carbon airbox and air filter improves the engine electronics and tuned to the changed parameters.
What comes out is simply sensational: The M3 CS 460 now has a power increase of 40 hp and a torque of 460 Nm (serial 400 Nm) depends so directly on the gas as if the nervous system of the driver directly connected to the throttle. The motor rotates completely in harmony to 8,500 U / min. Before the shift lights to warn train on the shift lever. The weight reduction of more than 70 kg can be linked to the performance of the M3 CS 460 in 4.1 s from 0-100 and from 0-200 sprint in 13.2 sec (range 15.7 s)
The best is yet to come: Only on twisty turf you notice the true qualities of increased 3ers. He draws a jagged, almost panting for the next corner and curled exciting and completely neutral to any kind of bending. You can feel how perfect suspension and the excellent Michelin Pilot Sport Cup in harmony with each other and build maximum mechanical grip. The reduction in rotating unsprung weight has a positive from this and not even leave the comfort component to come shortly. The ceramic brake system is the whole of the top one better. These bites on as if there were no tomorrow. Well that the pilot is firmly fixed in the 7.4 kg lightweight Recaro Pole Position bucket seats. The vehicle is emotion and pure driving pleasure. Just the pleasure of the eye on the precious components made of titanium, aluminum, ceramic and carbon migrate to and to thereby secure just the best of everything in front of him to have been worth the investment. The cherry on top of the a-workx M3 is the sound that the fine titanium Akrapovic Evolution exhaust system elicits from the high-revving V8. This makes up the neck hairs while simultaneously conjures a wide grin across his face. As I said, pure driving fun!
