BMW has released a factory tuning package for its N54 twin-turbo engine, found under the hood of the 135i and 335i models.

Though the press release refers only to the German market, expect the performance power kit to be available to most of Europe and the US soon.

Releasing the extra power is an engine management upgrade and air intake modification. However the performance upgrades are not the result of some simple ECU chipping job and include an additional radiator, fronted by a high-flow veined fan for extra cooling.

The sum total is a power boost from 225kW to 240kW and 30Nm of extra torque – now peaking at 430Nm. If owners install the kit in an automatic 335i or 135i, the torque peak is bumped up by another 20Nm to 450Nm. BMW claims the performance power kit fitted to a 335i, should make for a zero to 100km/h time of 5.4 seconds, a gain of 0.2 seconds over the standard car.

In its never-ending quest to satisfy the power-thirsty tuning crowd, Hartge has developed a new performance package for the BMW 135i Coupe that gives the twin-turbocharged 3.0-liter inline six a power boost of 32kW through a new ECU module raising total output to 257kW at 5600rpm and maximum torque to 480Nm at 2950rpm.

The Hartge prepped 135i Coupe dashes from 0 to 100 km/h in 4.8sec or half a second faster than its standard brother while it achieves a top speed of 280km/h. Despite the increased performance, Hartge supports that average fuel consumption is the same as the standard model, at 9.2l/100 km.

Engine tuning aside, Hartge’s performance pack for the BMW 135i Coupe includes a full bodykit that consists of a front spoiler lip, roof spoiler, lip for boot lid, rear diffuser and side sills complemented by 20-inch alloy wheels fitted with Pirelli P-Zero Nero tires (245/30 ZR20 front and rear) and a 25mm lower sports suspension.

Other improvements include a sports exhaust system, decals and Hartge logos and a set of carbon (silver or black) casings for the exterior mirrors.

HARTGE also offers a 3-spoke leather steering wheel with silver (or black) carbon inserts. The same material is used for the interior trim for the dash board, gear lever panelling and door handles. The interior enhancements are completed by an illuminated gear knob, including an alcantara gaiter for the 6-speed manual gear box and the handbrake handle in a combination of leather and aluminium.
