German tuning haus Hamann has released its new 3-series coupe modifications, which encompass everything from power upgrades to aero parts and interior options. Currently, the kits are available for the 325i, 330i, 330d, and 335d coupes, with a kit for the 335i in the pipeline.

The six-cylinder petrol engines in the 325i and 330i receive a boost of 13bhp/10 kW and 17bhp/12kW and in both cases around 25Nm 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.

When it comes to the diesel models, you get an even bigger power boost. Hamann has managed to tweak the engine in the 330d to 272bhp/200kW, 259km/h top speed (standard: 248) and 600Nm at 2000rpm. The top diesel model gets 313bhp/230kW, 272km/h and a more than generous 630Nm at 2000 rpm. A power boost to around 380bhp for the 335i is currently in preparation.

HAMANN boosts the power in this coupe by means of optimized curve maps. In other words, the electronic power boost is achieved by recalibrating the standard ECU.

The new, sportier-looking HAMANN front spoiler is designed to be fitted onto the standard bumper. The visual lowering effect is created by the new side sills, which lend the side view more character. The vehicle’s back can either be customized with a HAMANN rear spoiler or a spoiler lip. The same effect is produced by the HAMANN roof spoiler, which sits on top of the vehicle. The rear center molding, which incorporates matching cutouts for the tailpipes, is designed to be used in conjunction with the HAMANN 4-pipe sports rear muffler. Fitting Carbon-Kevlar mirror caps give the HAMANN 3 Series coupe a further eye-catching touch.

Hamann also offers no fewer than four different wheel designs and three sizes from 18 to 20 inch.

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.

On the inside, you get a three-spoke HAMANN airbag sports steering wheel as well as 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.
