The BMW 320si is a sporty 3 Series that has many similarities with the WTCC car. Only 2600 where ever produced in limited edition. The car is equipped with an M sports package, which means that the front and rear bumpers, side skirts, front fog lamps and mirrors have been modified. In addition, the car comes with special rims and a decorated interior. Think of sports seats, M steering wheel, poker and aluminum pendals. In addition to the appearance, the chassis and engine have also been modified. The 2 liter four-cylinder now produces 175 hp instead of the standard 150 hp. As icing on the cake, the valve cover is made entirely of carbon, which gives the car a unique look. (don't lose it, they're really expensive to replace)
Engine is completely overhauled and the throttle body replaced in 2021.

In short: This is not an M3, but a nice, decorated 320, with slightly more power and a unique appearance. With that you will be able to distinguish yourself from the rest of the e90s on the road because only 2600 were made.
