In a world where performance wagons are rare gems, G-Power has taken the crown jewel of BMW’s lineup—the M3 Touring—and transformed it into an unapologetic, fire-breathing, 789-horsepower monster. Meet the G-Power G3M Bi-Turbo, a heavily modified version of the BMW M3 Touring that doesn’t just blur the lines between practicality and performance—it shatters them.
With a top speed of 205 mph and styling that demands attention, this super wagon redefines what it means to drive a family car with flair. But G-Power’s latest creation isn’t just about raw speed; it’s a complete transformation of the beloved M3 Touring platform, enhancing power, aerodynamics, visual drama, and driving excitement. Let’s take a closer look at why this build is one of the most thrilling performance wagons in the world.
BMW M3 Touring: The Base for Greatness
Before diving into the G-Power modifications, it’s worth appreciating what BMW has already achieved with the M3 Touring. The long-awaited BMW M3 Touring G81 debuted with much fanfare, combining the everyday practicality of an estate (or “wagon” for our U.S. readers) with the brute performance of the M3 Competition xDrive.
At its core lies a 3.0-liter twin-turbocharged inline-six engine—known as the S58—which delivers 503 horsepower and 479 lb-ft of torque in factory form. That’s enough to launch the standard M3 Touring from 0 to 60 mph in just 3.5 seconds.
It also features BMW’s M xDrive all-wheel-drive system, offering improved traction and cornering capabilities. The M3 Touring is a driver’s car at heart, offering daily usability without compromising its motorsport DNA.
Enter G-Power: Raising the Bar with the G3M Bi-Turbo
While the stock M3 Touring is already a masterpiece, G-Power —a legendary name in the BMW tuning scene—thought there was room for more… a lot more. Their answer? The G3M Bi-Turbo, a high-performance wagon that goes beyond M Division’s wildest dreams.
G-Power’s engineers upgraded nearly every performance-related component of the vehicle, beginning with the heart of the machine: the S58 engine.
Massive Power Gains: From 503 HP to 789 HP
To boost output to 789 horsepower and 664 lb-ft of torque (900 Nm), G-Power:
- Swapped the stock twin turbos for larger, high-efficiency turbochargers
- Installed a new stainless-steel exhaust system with 200-cell high-flow catalytic converters
- Upgraded the ECU with custom performance software tuning
- Optimized airflow and thermal management to ensure performance longevity
These changes don’t just offer more power—they unleash a different character in the car. The throttle response becomes sharper, the torque delivery broader, and the exhaust note more aggressive.
205 MPH: Supercar Speeds in a Family Body
G-Power didn’t release official 0-60 mph times, but with 789 horsepower and all-wheel drive, it’s safe to assume a figure well below the 3.0-second mark. The bigger headline? A top speed of 205 mph (330 km/h).
That’s faster than many supercars—and in a car with five seats and a usable trunk, no less. The G3M Bi-Turbo enters the rarefied realm of performance wagons like the Audi RS6 Avant Performance, Porsche Panamera Turbo Sport Turismo, and even the Ferrari GTC4Lusso, with one key difference: It’s based on a production BMW family wagon.
Voodoo Blue and Orange Pop: Visual Upgrades
If you thought G-Power would stop at performance upgrades, think again. The G3M Bi-Turbo’s exterior design is as bold as its power figures. The car shown off in their promotional photos is finished in Voodoo Blue, a vibrant and exotic BMW Individual color that contrasts sharply with bold orange accents.
- Carbon fiber hood with an aggressive center air vent, aiding engine cooling and reducing weight
- Carbon fiber front splitter, wing mirrors, and rear diffuser to improve aerodynamics
- G-Power’s signature Hurricane RR forged wheels, finished in matching orange, which not only look striking but also reduce unsprung weight for better handling
This isn’t just a styling exercise—the visual upgrades also serve functional purposes. The carbon components help improve downforce and engine bay airflow, while the wider wheels offer better grip under hard acceleration and cornering.
Interior Reimagined: Luxury Meets Motorsport
Open the door, and the G3M Bi-Turbo’s cabin continues the theme of extravagant performance. G-Power re-trimmed the interior with bright orange leather, covering the:
- M Carbon bucket seats
- Dashboard and door panels
- Center console accents
This bold color choice might not be for everyone, but it matches the car’s dramatic exterior and reflects its high-performance mission.
At the same time, the interior retains all the comforts of a premium BMW: wireless Apple CarPlay, BMW’s iDrive infotainment, high-end Harman Kardon audio, and advanced driver assistance features.
The Legacy of G-Power: Tuning Excellence Since 1983
G-Power has a storied history of turning already-fast BMWs into record-setting machines. Known for creating some of the world’s fastest BMW sedans and coupes, the German tuner gained notoriety with models like:
- The G-Power M5 Hurricane RS, once the fastest sedan in the world
- The G-Power G1 V8 Hurricane, a BMW 1 Series stuffed with a supercharged V8
- Multiple 800+ horsepower builds using BMW’s M V8 and inline-6 engines
Their approach isn’t just about throwing in bigger turbos—they focus on reliability, performance balance, and daily usability. That’s why the G3M Bi-Turbo isn’t just a dyno queen—it’s a road-going beast that you can (theoretically) take to the grocery store.
Who Is the G-Power G3M Bi-Turbo For?
Let’s be real—this isn’t your average school-run car. The G3M Bi-Turbo is for the enthusiast who:
- Needs practicality but refuses to compromise on performance
- Wants to own one of the fastest wagons on the planet
- Appreciates bold styling and exclusivity
- Might occasionally hit the Autobahn or a closed track
Whether you’re a BMW loyalist, a high-speed thrill-seeker, or simply someone who wants to own something rare and outrageous, this tuned M3 Touring delivers.
