2011 BMW 3 Series Convertible will debut in 2011 or probably at the beggin of 2012. What you see in these pictures is just a prototype that had been caught testing. I was amazed not to see the normal cover sticks from BMW because with these ones, the car looks unfinished.
When 2011 BMW 3 Series Convertible will be lunched, will have the EfficientDynamics on it. There are also expected some changes made at the interior of 2011 BMW 3 Series Convertible. The car will be available with 1.5 liter engine developing between 150 and 170 horsepower and a torque between 150 and 220 pd-ft.
Another cool fact is the way air flows through and over 2011 BMW 3 Series Convertible; more details about the air conduct in next posts about 3 Series Convertible. People also expect to have a hybrid version of 2011 BMW 3 Series Convertible, just like on X6 and 7 Series (probably will be called ActiveHybrid 3). The single fact that I hate so much on this 3 Series is the weak 1.5 liter engine. I would expect something like 3.0 or at least 2.0 but maybe with that good dynamics is enough.
