Imagine driving a BMW M4 Convertible that pumps out 523 horsepower straight from the factory – enough to make most mortals say, “Thanks, that’ll do.” But G-Power, those German tuning madmen, aren’t content with average. Their G4M Hurricane Bi-Turbo Convertible takes the open-top M4 and transforms it into a 720-horsepower beast – the G-Power BMW M4 Convertible, which will outrun Ferraris and McLarens while you soak up the sun with the top down. Is that an exaggeration? Maybe. But in a world where speed is currency, it’s pure pleasure with a bit of irony – why have a supercar when you can have a convertible that costs less and delivers your coffee in style? Get ready for a ride that will awaken your inner racer.
G-Power is no stranger to the world of tuning. The company started in the late 90s with superchargers that boosted the E36 M3 from 286 hp (210 kW) to 400 hp (294 kW). Today, they're applying that knowledge to BMW's twin-turbo system. The G4M Hurricane Bi-Turbo Cabrio is based on the BMW M4 Competition Convertible, which has a 3.0-liter inline-six with twin turbochargers. G-Power upgrades it with the GP-720 package, which includes ECU optimization, an improved air intake, and their famous DEEPTONE exhaust system. The result? 720 hp (529 kW, 710 hp) and 850 Nm (627 lb-ft) of torque - almost 200 hp more than the stock. It's not just a number; it's a ticket to the world of supercars, where the convertible behaves like a rocket.
This heritage is no coincidence. G-Power is synonymous with German precision with a touch of madness. While BMW engineers say “enough,” G-Power says “why not more?” And the irony? At a time when the world is turning to electricity, they are still squeezing the maximum out of gasoline – and it works. The G4M model is not the first; we remember older Hurricane models, such as the 2021 G4M Bi-Turbo, which already reached 670 PS (493 kW, 661 hp), but this new one is a step forward with better integration and fewer compromises.
Design and visual upgrades: Subtle but effective
G-Power doesn't overdo it with looks – thank goodness, because no one wants a car that screams “look at me!” The GP-VENTURI carbon bonnet isn't just for show; its vents actually cool the engine during wild rides. The GP-SHURIKEN front grille and bumper corners improve aerodynamics, while the GP-HURRICANE RR forged wheels (probably in 20 or 21 inches) are built to handle speeds in excess of 300 km/h. The exhaust system has four pipes: two 100 mm and two 110 mm, all in carbon, which adds to that deep, resonant sound.
The exterior of the G-Power BMW M4 Convertible stays close to the original, but with enough detail to let you know it's no ordinary M4. Inside? Carbon fiber inserts on the dashboard, center console, and steering wheel—subtle, functional, and understated. This is a car for those who value performance over glitz, though, I admit, a little cynical: in a world where supercars are full of LED lights and wings, this convertible is refreshingly simple. And on the plus side? The open roof means you can enjoy the breeze while you outrun everything else on the highway.
Performance and technical specifications of the G-Power BMW M4 Convertible: the numbers speak for themselves
Here comes the heart of the matter. The original M4 Convertible does 0-100 km/h (0-62 mph) in around 3.7 seconds, but G-Power takes it to a new level. While exact acceleration isn't officially stated, we can expect under 3.5 seconds to 100 km/h, given the extra power. Top speed? A whopping 330 km/h (205 mph) – that's the territory of mid-engine exotics like Lamborghini or McLaren, but with the option of lowering the roof.
Engine: 3.0-liter twin-turbo inline-six, upgraded to 720 PS (529 kW, 710 hp) and 850 Nm (627 lb-ft) of torque. This is achieved without major mechanical changes – just ECU tuning, better air intake and exhaust. Consumption? Well, don’t expect savings; this is a car for fun, not ecology. Driving dynamics remain BMW’s: xDrive all-wheel drive, adaptive suspension, but G-Power adds options for better cooling and high-speed stability.
Let's compare: The standard M4 has 523 hp (385 kW, 517 hp) and 650 Nm (479 lb-ft), a top speed of around 250 km/h (155 mph) with a limiter. G-Power removes the limiter and adds power – the result is the G4M Hurricane Bi-Turbo Cabrio, which is faster than many supercars, but cheaper. And for those who don't want the full package: step-by-step upgrades from 600 hp (441 kW, 592 hp) onwards.
Key specs at a glance: G4M Hurricane Bi-Turbo Cabrio
- Model: G4M Hurricane Bi-Turbo Convertible
- Basis: BMW M4 Competition Convertible
- Engine: 3.0L twin-turbo inline six-cylinder
- Power: 720 hp (529 kW, 710 hp)
- Torque: 850 Nm (627 lb-ft)
- Final speed: 330 km/h (205 mph)
- Key components: GP-720 ECU tune, DEEPTONE exhaust, GP-VENTURI carbon cover
It's not just numbers; it's the feeling when you hit the gas and the world becomes a blur. But with an irony: in the city, you'll drive slowly so as not to scare pedestrians.
How much does this madness cost?
The full GP-720 package costs around €35,700 (about $41,630), which isn't cheap, but considering the performance, it's a bargain. Add that to the price of the base M4 Convertible (around €100,000) and get a supercar for the price of a premium sedan. G-Power offers modularity: start with an ECU tune for €3,685 and 600 hp, then add an exhaust or wheels. Available in Germany and through a network of partners – ideal for those who want personalization without waiting for the new generation M4.
Conclusion: Why do you have to have it?!
At the end of the day, it is G-Power G4M Hurricane Bi-Turbo Convertible more than just upgraded BMW – is a statement. In a world where electric cars promise a quiet future, this convertible screams with every rev of its engine: “Life is too short for boring drives.” From multiple sources like the BMW Blog and CarBuzz, we hear the same thing: this car exceeds expectations, offering brutal power without sacrificing comfort. Personally? As a car enthusiast, I see the cynicism in the exaggeration – do we really need 720 hp for our morning coffee? But at the same time, positively: yes, because why not? This is a car that finds a balance between madness and utility, between wind in your hair and speed that glues you to your seat.
If you're an enthusiast who wants a supercar experience without the supercar price, this is it. The price tag of around €40,000 for the upgrade seems fair for what you get: 330 km/h top speed, 720 hp of power and the ability to overtake a Ferrari on the motorway while soaking up the sun. But be warned: this is not for the faint of heart. Go for a test drive if you dare – and you might find that it's the best investment in fun. Share your thoughts in the comments: would you dare drive this beast? Is that an exaggeration? Either way, G-Power proves that there's still room for a little madness in motoring.
