Audi has revealed the model updates for the European-spec 2009 A3 and S3. Both are slightly larger than the previous version, and the S3 is now available in the 5-door Sportback version. The front of the A3 receives a freshened look including a more complex design around the grille and more modern headlights with optional bi-xenon units that incorporate LEDs. At the rear there is a modified tailgate and the taillight design uses fiber optic rods to create a pretty cool effect. The interior features new aluminum design trim and new colors and fabrics for the seats, and the controls for the audio system have been given a new look. As for the powertrain, the Euro-only diesel engines have been reworked to include an updated fuel injection system. All engine options are now available with the S tronic transmission, and the 1.6, 1.4 TFSI and 1.8 TFSI engines can be paired with a newly developed seven-speed version.

The rumormongers at AutoZeitung are reporting that BMW plans to unveil a stripped-out, track-ready M3 at the 2009 Frankfurt Motor Show. The E90-based M3 CSL will use many of the same tricks BMW employed on the E46 model in an effort to shave the coupe’s curb weight. Luxuries like air conditioning, stereo and navigation won’t be included, while the hood, bumper, trunk and fenders will all be swapped out in favor of carbon fiber pieces.

In addition to keeping the pounds down, BMW will reportedly boost the output of the M3 CSL by an additional 50 horsepower, for a total of 470 bhp. That should allow the E90 CSL run to 60 in around four seconds, on its way to a top speed of around 185 mph.

Production of the 2010 BMW M3 CSL will be limited to 100 units and pricing is estimated at 90,000 euro, or just over $140k.
