ovaj sivi je ziva perverzija, svaki M3 od kad pratim auto industriju mi se svidjao pa ne sumnjam ni u ovog...

Neko se igrao sa PSom, ali je odlicno ispalo.

Ovo je M4. Mislim da je to zvanicno prikazano kao koncept u Detroitu.


Edit: evo vam ovde slika sa predstavljanja koliko hocete:

Ahead of its debut (in concept form) sometime later this year, the production F80 M3 prototype forges ahead with testing this week at the Nurburgring. We've got it on video giving us probably the best listen so far at the F80 M3's multi-turbo inline 6.

According to the VIN info, the M3 will be powered by a 310kW (415 hp) 3.0L inline 6 engine (s55). Consistent with the information we've been posting, this would have the next M3 and M4 featuring similar horsepower figures to the current M3 (414 hp) from the 3.0L inline 6 multi-turbo s55 engine. But, we've also been previously told by a trusty source familiar with F80/F82 development that the cars will boast approximately 100 lb-ft more torque (in range of 395 lb-ft).

The rest of the info we know:

- Lighter than current M3 (targeting E46 M3 weight)
- More powerful than current M3
(approximately same HP, but around 100 lb-ft more torque (in range of 395 lb-ft))
- Faster than current M3
- More efficient than current M3
- Powered by an inline 6 cylinder multi turbo engine (source, source)
- Offered with DCT and manual transmission
- Offered with optional M Carbon Ceramic Brakes (photos)
- Electric Power Steering (completely reworked for precision for M3/M4)
- Tires (from prototype) - Michelin Pilot Super Sport: 255/35/19 (front), 275/35/19 (rear)
- Front styling to feature elements from the M6 and 1M coupe, with Air Curtain technology (our render)
- Hood to feature power/vent bump
- F82 M4 coupe to feature double-bubble sculpted carbon fiber roof (like M6 Coupe)
- M3 Introduced late 2013 - early 2014 (concept debuts earlier)
- M3 European Delivery begins June 2014, at earliest
- M4 Introduced no earlier than late 2014
