The M3 Cabrio.

The new M3 is once again available as a 4-door sedan, based on the E90 3-Series, but unlike the regular models, this car shares the coupe's front end, including headlights. However, it does not get the 2-door's carbon-fiber roof. The E93 hardtop convertible version joins the lineup shortly after the E92's launch, while an E91 wagon, which was due in the first quarter of 2009, has now been canceled. A CSL lightweight version is heavily debated and longed for amongst car enthusiasts, but while cars suspected to be the new M3 CSL have apparently been spotted at the famous Nordschleife (North Loop) of the German Nürburgring, the M division have stated that they do not plan to offer an e9x M3 CSL and are instead focused on producing M versions of the X5 and X6 in a significant departure from M's historic practices. The front-end design of the BMW M3 Sedan matches the specific look and high-performance character of its Coupé sibling; however the side-sills, front side panel “gills” and rear air dam are uniquely tailored for the sedan. The M3 Sedan is powered by BMW’s all-new 4.0-litre V8 developing maximum output of 309 kW (420 PS; 414 hp) and maximum torque of 400 N·m (300 lb·ft) at 3,900 rpm. The four-door M3 accelerates to 100 km/h (62 mph) in 4.9 seconds and records average fuel consumption in the EU test cycle of 12.4 litres/100 kilometres. The BMW M3 Cabrio/Convertible is based directly off of the M3 Coupe. The Convertible uses a power retractable hardtop which adds 441 lbs. to the weight of the car, bringing the total to 4,145 lbs. The Convertible also features a special leather surface for the seats that reflect sunlight to ensure the seats to not get uncomfortably hot with the top down.
