625 hp and 750 Nm of maximum torque as standard, acceleration to 100 km/h in
just around 3.2 seconds and a top speed of up to 305 km/h. These impressive
figures belong to the high-performance Gran Tourer M8, available in three body
styles. The G-POWER brand, which has specialized in BMW M optimizations for
more than 38 years, has now chosen the V8 luxury liner as the basis for higher
levels, transforming it optionally into the G8M HURRICANE RS with 840 hp or G8M
HURRICANE RR with 900 hp.
G-POWER was not only able to draw on the experience gained with the M8 over a period of more than a year, for example in the form of conversions to the G8M Bi-TURBO – numerous examples have already been optimized during this time. In addition, the team benefited enormously from the results of the HURRICANE development work for the corresponding optimization program for the F90 M5. In
fact, in the spring of 2020, the team from Aichach had already presented the
HURRICANE RS version of the G5M based on the high-performance sedan. This
was followed a few months later in the fall by the even more powerful G5M
HURRICANE RR. Although the G8M HURRICANE is brand new, its technology has
been tested and proven for many months. After all, it has the same 4.4-liter biturbo
V8 engine (S63B44T4) as the M5 and thus also adopts the respective G-POWER
packages for performance enhancement.
In the case of the HURRICANE RS, the G8M gets the GP-840 performance
software as well as several hardware optimizations: G-POWER upgrade
turbochargers with enlarged intake and exhaust areas and CNC-milled housings are
installed, as well as a DEEPTONE stainless steel exhaust system that flows into
four carbon-sheathed 110-millimeter tailpipes and connects to the eight-cylinder
engine via sport downpipes complete with sport catalytic converters. The bottom line
is an output of 840 hp and 1,050 Nm of maximum torque. The top speed remains
limited in consideration of the tires, but the maximum has been raised significantly
and now stands at a governed 340 km/h.
The G8M HURRICANE RR is even more brutal. In addition to the GP-900
performance software and the G-POWER hardware modifications also installed on
the RS, there are additional optimizations, such as the HURRICANE engine
conversion with forged pistons, modified connecting rods, as well as a larger cooling
package and a reinforced drivetrain. Thus, the 4.4-liter V8 comes to 900 hp and
(limited) 1,050 Nm of torque; the top speed is also electronically limited to 340 km/h.
G-POWER attaches great importance to all performance upgrades, not only to the
greatest possible increase, but also to good drivability and durability. This means
that all packages are thoroughly tested on the test bench during development, and
all components are manufactured to fit precisely and matched to each other. A
significant contribution to the engine thermal management is also made by the
G-POWER-VENTURI carbon front hood, which improves the ventilation of the
engine compartment with its “Dynamic Venting” technology. Complementing this is
the large, fixed GP-DYNAMIC RR wing on the rear. Made entirely of carbon, it has
motorsport quality and is particularly lightweight and stands on CNC-milled aluminum feet. It not only provides a visual highlight, but also increases the contact pressure.
The G8M presented here are real eye-catchers thanks to their radiant full-foiling
in the equally stimulating and alerting color HURRICANE Orange Metallic.
To round off the optical refinement, G-POWER offers two different in-house rim
sets: The choice is between the HURRICANE RR or the HURRICANE RS forged
wheels, each in 9×21 inch and 10.5×21 inch with tires in 285/30ZR21 and
295/30ZR21. The perfectly fitting, variable lowering is achieved by the G-POWER
coilover suspension Variant 4, which furthermore allows an adjustment of the
rebound and compression damping. And even the interior is not disregarded by
G-POWER: The G8M HURRICANE RR comes standard with an extensive, hand-
finished interior featuring the finest materials such as leather, Alcantara, and
carbon. It is available as an option for the HURRICANE RS.
