The Big Block increased capacity engine for the new BMW 760i / Li
HAMANN HM 7.0 with 510 hp / 375 kW, 728 Nm and 311 km/h maximum speed



Extra capacity instead of turbocharging: HAMANN (Internet: www.hamannmotorsport. de) tunes the new BMW 760i / Li into a new dimension of performance with the HAMANN HM 7.0 increased capacity engine: With 510 hp / 375 kW and 728 Nm of maximum torque the tuned luxury limousine accelerates from 0 - 100 km/h in 5.0 seconds only and is 311 km/h fast.


The 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 cylinderheads 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 600 Nm to 728 Nm at 4,200 revs. Accordingly the road performances of the 760i/Li are improved: The tuned luxury limousine only takes 5.0 seconds from 0 - 100 km/h. Maximum speed is 311 km/h.


BMW 745i / Li models can be upgraded with the HM 5.0 increased capacity engine delivering 412 hp / 303 kW at 6,100 rpm and 535 Nm of maximum torque at 3,900 revs. The tuned V8 luxury limousine accelerates in 5.8 seconds from 0 - 100 km/h. Maximum speed is 282 km/h.


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


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. The multi-piece five spoke rims with high polished outside well perfectly fill the wheel houses in sizes 9.5Jx22 front and 10.5Jx22 or even 11.5Jx22 on the rear axle. They chose the dimensions 265/30 ZR 22 in front and 295/25 ZR 22 rear as optimal tires.


Alternatively HAMANN Tuning provides different other one-piece and multi-piece light alloy wheels in different designs and 18-, 19- and 20 inch diameters for the BMW top of the line model.


The HAMANN tuning program for the BMW 7 Series of the E 65 / E 66 / E 67 range also provides 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 Tuning offers progressively coiled sport springs. With them the bodywork is lowered about 40 millimeters front and about 20 millimeters rear.
