If you couldn’t already tell from the torrent of spy photos featured on the BIMMERPOST homepage, manufacturer testing season has opened on the Nurburgring.

On the track today was this F32 4 Series (435i) with M Sport package revealing for the first time the aggressive shape of the M Sport front bumper. Compared to the F30 3 Series M Sport front fascia, the 4 Series M Sport bumper is more angular, with air vents that angle upwards and expands as it gets closer to the outside of the front bumper.

We have added photos from the latest spotting of the BMW M4 Coupe (F82), together with a short clip from testing on the Nurburgring track.

Alpina trotted out its upcoming B6 Gran Coupe for some Spring time testing and we’ve caught it fitted with Alpina front lip, trunk wing, wheels and exhaust system. The aero parts remain unpainted and no Alpina rear diffuser/bumper has yet been installed.

For an idea of what the specs may be for the B6 Gran Coupe, the 2013 Alpina B6 Coupe features 540hp / 730nm (538 lb-ft) torque, with a top speed of 334 km/h – based on BMW 4.4L V8 motor. How do those specs stack up against the M6 in the performance department? Check out the Sport Auto comparo results below.

The M5 M Performance Exhaust system is titanium construction, 12 feet in length and 33 pounds lighter than the factory M5 exhaust. It will come in two versions – one with titanium steel tips (as pictured below) and a carbon fiber tip version. The titanium tips feature an M engraving and we imagine the carbon fiber may also feature some graphic or emblem.

Have a look at the latest F33 4 Series convertible prototype, revealing more of its defining characteristic – its metal folding roof. Earlier spyshots (reposted below) show the hard top operation and the design is largely similar to the current E93 convertible.

The F33 will share the same engine and transmission options as the F32 coupe, as well as the coupe’s general styling. So, imagine the coupe that you’ve seen revealed, but with this metal folding top.

Production of the 4 Series convertible (both 435i and 428i) begins later this year – in November 2013.
