Hamann from Laupheim, Germany, has already begun with modifications for the youngest 3-Series Convertible. An aerodynamic kit, power boost, new wheels, suspension components, as well as stylish interior enhance the sporty elegant features and improves driving performance of this Bavarian beauty.

Power Boost for Gas Engines and Diesels

Hamann boosts the power in this Convertible by means of optimized curved maps. Meaning, the electronic power boost is achieved by recalibrating the standard ECU. The four-cylinder model 320i receives Hamanns boost of 10 bhp and 7 lb-ft of torque, enough for a 3 mph higher top speed. The six-cylinder gas engines 325i and 330i experience a plus of 13 bhp and 17 bhp and both about 18 lb-ft of torque as well. Top speed climbs to 155 mph, respectively 165 mph. Included in price for the 330i is deactivation of 155 mph speed restriction. Likewise the 335i receives a power boost of 37 bhp and an impressive 174 mph top speed. For easier breathing capabilities of the 6-cylinder model Hamann offers a sport air filter.

For the current diesel model 330d customers can expect a significant power boost to 272 bhp, making possible a top speed of 157 mph (standard: 150 mph) and 443 lb-ft of torque at 2000 rpm/min.

By fitting a Hamann 4-pipe sports rear muffler with four round tailpipes, the 335i publicizes its power. The four stainless steel tailpipes, each 76mm in diameter, make the rear end of this Convertible even more attractive.

Powerful Sport Aerodynamics

Wheels from 18 to 20-inches

Hamann really goes to town when it comes to wheels. Three unique individual designs and three sizes from 18 to 20 inch make selection difficult. A multispoke design is featured in the single-piece rim Anniversary I is available in silver finish and features an outer rim with an INOX steel lip. Hamann offers it in 18, 19 and 20 inch versions. The wheel PG3 is a multiple five-spoke composite wheel in silver with a high-gloss polished rim flange. Here customers can choose between sizes 19 and 20 inches.

Unquestionably, 20 inch wheels suit the customized 3-Series Convertible best. Hamann offers this size as top model design Edition Race. The appearance of this three piece, ultra-lightweight, forged rim is a cross-spoke design with a black spider characterized by the 9 main spokes, each of which branches outwards into 2 further spokes. Following this exciting design, the titanium bolts are a particularly attention-getting design. The high-gloss rim flange adds the finishing touch to this stylish look.

Typical wheel / tire combination in 20 inch:
Edition Race: front 8,5 J x 20 / rear 10,0 J x 20 - 235/30 ZR20 / 285/25 ZR20
PG3: front and rear 8,5 J x 20 - 235/30 ZR20
Anniversary I: front and rear 9,0 J x 20 235/30 ZR20

Choice of combination with wider rear axle tires is possible for all 19 and 20 inch versions from Anniversary I and PG3 as in the case of Edition Race wheels as well. Hamann provides advice as requested regarding all possible combinations.

Better Handling and Powerful Gripping Brakes

By fitting a suspension lowering kit comprising of four progressive suspension struts, Hamann succeeds in lowering the vehicles center of gravity by 1.4 inch front and by 0.8 inch rear. For vehicles with sport suspension tuning systems from stock, that's still around 0.0 inch. In both cases, a clearly better handling results. Among race drives it is said races are won on the brakes. For those who prefer to use somewhat more rapid acceleration, Hamann program suggests powerful gripping brakes for security purposes.

Interior designed with numerable accessories creates an even more pleasurable stay in Hamanns 3-Series Cabrio. Thanks to the three-spoke Hamann airbag sports steering wheel, the drivers hands always hold the reins securely. A sporty flair is added by the decorative carbon-fiber components, which Hamann fits to the dashboard, center console, ashtray trim, doors, steering wheel, gearshift knob, handbrake lever and the I-Drive-Controller. Hamann adds further sporty nuances in the form of sport gearshift knobs (in aluminum or leather/aluminum), aluminum pedals, an aluminum handbrake lever and an aluminum footrest. An exclusive set of floor mats sporting the Hamann logo in silver rounds off the interior offerings.

Of course, Hamann customizes every 3-Series to individual customer requests. For example, luxurious leather upholsteries in a variety of colors are possible, as are extensive multimedia conversions featuring DVD player, TV or Playstation.
