2003 Hamann HM 7.0

A Big Block engine for the new BMW 760i/Li.

Extra capacity instead of turbocharging: Hamann catapults the new BMW 760i/Li into a new dimension of performance with the Hamann HM 7.0 increased capacity engine. The Hamann capacity increase to 7,080 cm3 is made via the installation of a special crankshaft, the boring up of the cylinders and the fitting of bigger forged pistons. In addition the two cylinder-heads of the V12 four valve engine get machined and sport camshafts are installed. The tune-up also contains modifications on the air induction, the installation of a stainless steel made high performance exhaust system including special manifolds and metal-bed catalysators and a recalibrated ECU which perfectly coordinates all components. Of course the modified ECU also eliminates the standard electronic speed limit of 250 km/h.

The conversion to HM 7.0 specification improves maximum power from standard 445 hp (327 kW) to 510 hp (375 kW) at 6,000 rpm. Simultaneously the maximum torque grows from 442 ft lbs (600 Nm) to 536 ft lbs (728 Nm) at 4,200 revs. Accordingly the road performances of the 760i/Li are improved: The tuned limousine only takes 5.0 seconds from 0 to 100 km/h.

Hamann also offer stainless steel sport exhaust systems for all current BMW 7 Series models which are available with or without exhaust manifolds and metal bed catalysators.

Chassis

To realize these road performances it is necessary to fit special high performance tires. Hamann furnishes the 7 Series BMW with HAMANN PG3 22-inch light alloy wheels. They require 265/30 ZR 22 in front and 295/25 ZR 22 rear as optimal tires.

The Hamann tuning program for the BMW 7 Series range also includes the high performance brake system with vented and perforated 380 millimeter discs and
8-pot calipers on the front axle.

To give the new BMW a wedge-shaped lowering, Hamann offers progressively coiled sport springs. With them the bodywork is lowered about 40 millimeters front and about 20 millimeters rear.

Body

The modern design of the 7 Series can be refined using sporty yet elegantly styled Hamann bodystyling components. The Hamann front spoiler, which is fixed on the standard bumper, doesn’t only give the car a more prominent face, it also minimizes the lift on the front axle at high speeds.

The Hamann side skirts and door panels make the limousine look lower and more stretched. The rear panel with integrated diffuser harmonically rounds out the exciting design of the Hamann body conversion in conjunction with the sport side mirrors.

In addition, the 7 Series can be made even more individual with the roof wing and rear spoiler.
