Software update for the G8x M4 / M3 with up to 700 hp

The design of the front will certainly polarize opinion, but what is also certain is that the BMW M3 and M4 of the current generation G8x are exceptional midrange high-performance sports cars. The coupé and the sedan – in the rear-wheel-drive version – both shifted their striking kidney grilles into the spotlight in September 2020,with the four-wheel drive version and the cabriolet G83 following during the course of 2021. Of course, these top models quickly became the darling of the performance and tuning sector. But the predecessor– the F8x–along with
the
M2,
was
and
remains
one
of
the
absolute
stars
of

the
scene,
not
least
thanks
to
the
special
model
variants
such
as
the
CS
and

GTS.
The performance specialists at G-POWER, a brand which has been delivering
impressive performance upgrades for BMW M vehicles for almost 40 years,
are also offering their own superb take on the “old” F8x series with the G4M /
G3M Bi-TURBO, which is available in multiple power levels up to 700 hp. And
now, their story of success is to get a new chapter as the model enters the
second round!
The G4M Bi-TURBO and G3M Bi-TURBO are true world firsts! All power
upgrades for the G8x to date are achieved using an additional chip tuning box.
But G-POWER is doing things differently! The first levels of their power
upgrade have been developed and involve tuning software installed directly on
the factory-fitted control unit: With the help of GP-600 software, the BMW can
now deliver 600 hp. The next step up is the GP-650 software and the
DEEPTONE exhaust system, which combine to unlock 650 hp in the twinturbo
six-cylinder
engine.
The
current
maximum
is
the
700
hp
variant,
in
which
GP-700
software
with
sports
downpipes
and
the
DEEPTONE
exhaust
system

are
used.
With
these
G-POWER
power
boosts,
a
new
top
speed
of
207
mph
is
possible.
Furthermore,
the
maps
of
the
G-POWER
software
are
tailored

precisely
to
the
specific
vehicle
and
specific
engine
at
the
performance
testing

station.
This
allows
for
a
much
more
individual
and
customized
power
boost

than
with
an
additional
tuning
box.
When it comes to power boosts, G-POWER puts great value on good
drivability and endurance. All these power levels have therefore been
subjected to comprehensive long-term tests and passed them with flying
colors. The new G3M and G4M conversions will be available from December
2021. In addition, another power level of approx. 750-800 hp is in
development, which will be achieved using GP-800 upgrade turbochargers.
In terms of cosmetic enhancements, G-POWER is offering its well-known and
well-loved HURRICANE RR and HURRICANE RS forged wheels for the new
M3 and M4, respectively – either in 20″ at the front and 21″ at the back with
285/30ZR20 and 295/25ZR21 tires or in 21″ all around with 255/30 and 305/25
tires. The last option with 21″ all around is only available in conjunction with GPOWER
V4
coilover
suspension.
This
allows
for
variable
chassis-lowering
of

between
15
and
40
mm
and
hardness
adjustment
in
rebound
and
compression.

Additionally, from the beginning of 2022, G-POWER’s famous VENTURI
carbon front hood and the GP-DYNAMIC rear wing will also be available for
the M4 / M3: The hood improves the ventilation of the engine compartment
thanks to its “Dynamic Venting” technology and thus makes a significant
contribution to engine thermal management. Likewise, the carbon G-POWER
DYNAMIC spoiler on CNC-milled aluminum feet not only serves an aesthetic
purpose, but also increases the contact pressure on the rear axle. And for
power values in the region of 700 hp and beyond, this is exactly what is
required for dynamic and reliable handling – especially if the client has chosen
the rear-wheel drive M4 / M3. In other words, it is the perfect way to round off
the G4M / G3M Bi-TURBO.
