engine v10 530 hp
0 to 60 in just 4.2 seconds

Where are the pics??? That kind of performance in a four door sedan is just incredible...

V10!!! 7 SPEED GEARBOX!!! 4 DOORS??? BMW better make this concept a reality. Not only the most beautiful BMW but maybe the fastest 4 door ever. Talk about a Luxury sedan sleeper. Shure as hell will have the euro kids wondering why all they see is tail lights.
