The biggest news surrounding the 2007 BMW 3 Series E93 Convertible is that it now features a metal folding roof. This improves security in general and also makes it far more acceptable to drive in bad weather.
BMW says that it's new mid-sized open-top cruiser delivers the ultimate in performance and refinement thanks to a number of innovations. One, it features the first electronically operated folding hard-top roof offered by BMW, and two, is the world's first car to be offered with SunReflective seat cooling leather and a brace of all-new powerplants.

The fourth generation of BMW's open-top 4-seater heralds a new chapter in the history of the BMW Cabriolet, explains the Bavarian automaker, which at the same tries not to cast too much doubt on its existing triple-layered fabric roofs (currently showcased in the 6 Series Convertible and the Z4 Roadster) by adding that they are allegedly unsurpassed in heat and noise insulation.
But now the new 3 Series model comes with a 3-piece electronically-operated retractable hard-top, which not only offers better protection from thieves and weather, but also looks a lot smoother and sleeker than a cloth-roofed vehicle.
Stowed or raised in approximately 22 seconds, the new roof has been introduced not only for added security says BMW, but also for better visibility and a greater feeling of space and light for occupants. Because the roof features a larger rear glass windscreen and side windows, visibility has improved by 38 per cent compared to the old 3 Series Convertible.
The unique way in which the roof folds also maximizes available boot space. With the roof up 350 litres of storage capacity beckons, which is very large for a convertible, while with the roof down the boot can still accommodate up to 210 litres of luggage. In another world first, the rear seat backrests of the 3 Series Cabriolet can also be folded flat to provide additional storage space.
As an option, a through-loading system with transport bag can also be specified to allow for longer or bulkier items to be accommodated and it can still be used when the folding metal roof is lowered. For added practicality, a stowed roof can be electronically raised out of the boot area to allow for longer items such as golf clubs to be secured before being folded away again says BMW.

The new BMW 3 Series Convertible can also be specified with the world's first Sun-Reflective Technology leather upholstery. BMW explains that owners of BMW's latest 4-seat sun-trap can enjoy the warm weather and leave the roof down for prolonged periods without singeing themselves on the seats or armrests. Special pigments embedded into the leather help reflect infra-red radiation ensuring treated areas that are exposed to sunlight for a prolonged period can remain up to 20 degrees cooler compared to untreated leather.

The Convertible's platform is derived from the Coupe's, strategically reinforced to ensure that it is the stiffest, strongest and safest Convertible body-chassis unit BMW has built. In fact the E93 claims to be a whopping 50 per cent stiffer in the body than the previous model. All-up, the new Convertibles weigh about 1665kg and 1735kg respectively, or about 200kg more than the Coupes. Since that's about the same difference as in the previous pairs of open 3 Series, the latest structure is a significant advance in weight-versus-rigidity terms. Around 80 per cent (160kg) of the weight increase is owed to the chassis reinforcements, with the roof accounting for the other 40kg. All this extra weight translates in a smaller top speed and acceleration than the 3 Series E92 Coupe. Most probably the drivers won’t notice that since driving with the breeze in your hair will highly compensate these figures. 

For now only 5 engines are available for the E93: the entry-level 320i, 325i, 330i, 330d and top of the range the 335i. See the tables below for technical details.
