FOLLOWING SPY PHOTOS of a lightly camouflaged 2010 BMW M3 Convertible published in December, a completely unfettered M3 Coupe has been spied testing in Europe this week.
As with the recently-revealed 2010 3 Series Coupe, the updated M3 bears new LED tail lights. Externally, the styling tweaks appear to end there, with front-end seemingly missing out on the slight updates given to the regular Coupe.
Improved trim updates are likely to show in the 2010 M3's cabin, along with the new fourth generation iDrive system featured in the recently unveiled 2010 5 Series.
Output from the M3's 4.0 litre V8 is expected to move into 2010 unchanged from current levels, developing 310kW and 400Nm of torque.
Reports in March suggested that the next-generation M3 - beyond the E90/92/93 bodyshape - will be powered by a twin-turbo six-cylinder, separate from the twin-turbo in-line six featured in the current 335i and 135i.
M division boss Ludwig Willisch told Motor Trend that of the options available, a V6 would offer a more compact arrangement, allowing for better balance.
