Can be tuned to produce more than 500 HP (367 kW)

There's no shortage of tuning packages for the BMW 1-Series M Coupe, but that hasn't stopped LEIB Engineering from taking a crack at it.

Dressed in a matte grey foil wrap, the car has been equipped with a carbon fiber trunk-lid spoiler, an Alpha-N diffuser, a Bilstein sport suspension and 20-inch Bavaria BC5 Concave wheels with Yokohama Advan Sport tires.

While the car's styling won't win everyone over, the twin-turbo 3.0-liter inline six-cylinder engine has been equipped with an optimized ECU and a Supersprint sports exhaust system. This enables it to produce 400 HP (298 kW) and 560 Nm (413 lb-ft) of torque - an increase of 60 HP (44 kW) and 60 Nm (44 lb-ft).

The model can also be equipped with larger turbochargers, a "suction system" and a completely revised cooling and exhaust system. These modifications enable the engine to produce more than 500 HP (367 kW) and 600 Nm (442 kW) of torque.

After LEIB Engineering, the tuners from Gießen, demonstrated impressively that efficient suction

tuning is not a relic from the past and also quite interesting for current motor generations with

their M3 GT500 and E92 GT300 project vehicles in the last few months, Dominik Leib and his

team now emphasize that they are perfectly capable in the area of performance and sound

optimisation of charged vehicles as well by tackling the 1 series M Coupé.


It is known that the muscular special one's cowl hides the strongest development stage of the

N54B30 serial six-piston engine. It was already legendary during its lifetime. With its forced

respiration by two exhaust turbochargers, it develops a remarkable 340 PS even in the serial

condition. LEIB Engineering subjected the biturbo drive to another performance increase after

which the datasheet shows a full 400 PS. LEIB also moderately increased its torque: Instead

of the serial 450 Nm (500 Nm with overboost), the unit now puts a powerful 560 Nm on the

crankshaft, even at the lower end of the speed range to warrant plenty of pressure on its back!


The power increase is also essentially supported by optimisation of the motor indices and the

LEIB Engineering flap exhaust system (made by Supersprint), which is constructed to prevent

power loss with the exhaust flap closed. The exhaust's voice ranges from a hum to an aweinspiring roar. LEIB Engineering programmed the flap position control to the M-button in the

multifunction sports steering wheel. The software was also optimised to remove the electronic

Vmax limit, so that the Turbo-Coupé may convert its newly gained power into thrust as well – a

speed of up to 306 km/h can now be reached. There's even more to it: In its largest development,

LEIB Engineering increased the N54B30's output to more than 500 PS and 600 Nm with larger

chargers, a suction system with a larger cross-section and completely revised cooling and

exhaust packages.


The Swiss LEIB customer had his vehicle customised visually as well: Originally painted a bright

Valencia orange, the vehicle received an elaborate full foil cover in a matte grey into which a

chequered plate look and the logos of the companies involved with the project were integrated

three-dimensionally by streetworkz customz from Mörschwil. The BMW Performance carbon

rear spoiler trunk lid was also partially covered with foil, while the Alpha-N tail diffusor one level

lower clearly exhibits a light-weight but high-strength high-tech composite with its characteristic

shimmer. The extended wheel arches of the masculine 1M are filled well by the 10x20-inch

Bavaria BC5 Concave wheels with Yokohama Advan sports tyres 255/30R20 at the front and

275/30R20 at the rear axle. Matching the installed Bilstein B16 PSS10 threaded chassis, the

single-part light-metal wheel rims are powder-coated in a noticeable baby blue.

with those blue rims, looks like galapagos boobies http://malialitman.files.wordpress.com/2010/12/boobies1.jpg
