The 325i and 330i are powered by a modified six-cylinder petrol engines: the power is increased with f 13 bhp / 10 kW and 17 bhp / 12 kW and in both cases around 25 Nm torque. The top speed goes up to 250 and 265 km/h respectively (standard: 325i 245 km/h, 330i 250 km/h). In the 330i, the price includes the deactivation of the 250 km/h speed restriction.

The 330d boosts now 272 hp and reaches a top speed of 259 km/h (standard: 248) and 600 Nm at 2000 rpm are quite possible. In the top diesel model 335d 313 bhp/230 kW, 272 km/h and a more than generous 630 Nm at 2000 rpm.

Hamann is also working on a power boost to around 380 bhp for the 335i is currently in preparation.

By fitting a HAMANN 4-pipe sports rear muffler with four round tailpipes, the 335i and 335d can make their power public. The 4 stainless steel tailpipes, each 76 mm in diameter, make the rear end of this convertible look even more attractive.

Wheels from 18 to 20 inch


HAMANN really goes to town when it comes to the wheels. No fewer than four different designs and three sizes from 18 to 20 inch make choosing difficult. The HM2 design, available in an 18 inch version, is a single-piece light alloy wheel with five spokes in the ‘Silver' finish and features an outer rim with an INOX steel lip. The single-piece rim Anniversary I has a multi-spoke design and is also available in the ‘Silver' finish and features an outer rim with an INOX steel lip. HAMANN offers it as an 18, 19 and 20 inch version. The PG3 wheel is a composite five-spoke wheel in silver with a high-gloss polished rim flange. Here, customers can choose between the sizes 19 and 20 inch.

Needless to say, 20 inch wheels suit the customized 3 Series convertible best. In this size, HAMANN offers its "Edition Race" design as its top model. The appearance of this three-piece, ultra-lightweight, forged rim in a cross-spoke design and with a black spider is characterized by the 9 main spokes, each of which branches outwards into 2 further spokes. In addition to the exciting design, the titanium bolts are a particularly eye-catching detail. The high-gloss rim flange adds the finishing touch to the stylish looks.

Typical wheel/tire combinations in 20 inch:


  • Edition Race: front 8.5 J x 20 / rear 10.0 J x 20 - 235/30 ZR 20 / 285/25 ZR 20
  • PG3: front and rear 8.5 J x 20 - 235/30 ZR 20
  • Anniversary I: front and rear 9.0 J x 20 235/30 ZR 20


By fitting a suspension lowering kit, comprising four progressive suspension struts, HAMANN succeeds in lowering the vehicle's center of gravity by 35 mm at the front and by 20 mm at the rear. Even in vehicles that come with sporty suspension tuning, that's still around 15mm.

Numerous accessories combine to make sitting inside the HAMANN 3 Series convertible all the more pleasurable. Thanks to the three-spoke HAMANN airbag sports steering wheel, the driver always has the reins securely in his hands. A sporty flair is added by the decorative carbon-fiber components, which HAMANN fits on 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 offering.

Needless to say, HAMANN will customize every 3 Series to a customer's own specific requirements. By way of illustration, luxurious leather upholsteries in various colors are possible, as are extensive multimedia conversions featuring a DVD player, TV reception and a PlayStation.
