BMW M5 G90 G-Power

The new BMW M5 G90 has undergone extreme tuning by G-Power, boosting the hybrid sedan's power to 1,013 horsepower and 1,200 Nm of torque. The complete upgrade package costs €31,297, making this one of the most radical projects in the modern automotive segment for 2026.

Even in its standard version, the BMW M5 G90 delivers 727 horsepower and 1,000 Nm, but the tuners wanted to unlock the potential of the hybrid platform. The result is a gain of almost 300 horsepower, taking the model into hyper-sedan territory. Customers can choose from several upgrade stages—ranging from 850 to 1,000 horsepower—allowing them to balance cost and performance.

The top-tier version includes not only software adjustments but also significant hardware changes. The package features sporty exhaust pipes with catalytic converters, a new GP-Deeptone exhaust system, upgraded intercoolers, and a carbon fiber air intake. This configuration improves engine cooling, increases airflow efficiency, and reduces exhaust backpressure, which is crucial for stable operation under high loads.

The base performance is already impressive: the standard M5 accelerates from 0 to 100 km/h in 3.5 seconds. With the 1,000 horsepower version, the main improvement is expected in acceleration above 100 km/h, where the extra power plays a key role.

The basis of the tuning package for the BMW M5, now a G5M Bi-Turbo, consists of extensive modifications to the V8 engine and its peripherals: it begins with an Eventuri carbon fiber air intake and a more powerful intercooler to supply as much cold air as possible to the combustion chambers. A fraction of a second later, the air is released through downpipes with 200-cell catalytic converters to the Deeptone exhaust system with valve control, where it also contributes significantly to the sound experience.

This project highlights the potential of hybrid V8s in the electrification era. Despite the shift to electric vehicles, these cars show that internal combustion engines still have untapped capabilities. Competitors like Mercedes-AMG and Porsche are also advancing with hybrid systems, but this power level remains rare even in the premium segment.

The tuning of the BMW M5 G90 to 1,000 horsepower is not just a demonstration of possibilities—it's a market signal that hybrid technology can compete with full-fledged supercars. The question is whether buyers are willing to pay for this level of performance.

It’s hardly a slouch in standard form, but Germany’s G-Power has increased the output of the G90 BMW M5’s engine to 1013 PS, or 999 hp. That’s up from the 727 horses with which the M5 leaves BMW’s Munich factory.

Furthermore, a more powerful intercooler is installed to keep the intake air well-cooled – crucial for consistent performance. The exhaust gases are then forced through exhaust pipes with 200-cell catalysts and reach a Deeptone exhaust system with valve control. This not only produces an incredible sound, but also ensures better flow. In other words: more power, a fuller sound, more excitement.

But not everyone needs 1,000 hp right away – that's why G-Power offers different levels of tuning. The entry-level option is 850 hp, which only requires a software update. And with a sports exhaust system, it's possible to reach 900 hp. Those who want 950 hp will also need new downpipes.

And for the complete upgrade of more than 1,000 hp, you will need an intercooler and a complete sports exhaust system. And, honestly, it wouldn't surprise anyone if it were possible to get even more power in the future.

Performance figures: Official numbers for the 1,000 hp version are not yet available, but just take a look at the standard model. The BMW M5 (G90) accelerates from 0 to 100 km/h in 3.5 seconds and from 0 to 200 km/h in 10.9 seconds.

The M5 is a plug-in hybrid, and adds a 194-hp electric motor into the mix, but G-Power doesn’t mess with the electrics. Instead, its focus is purely on extracting as much as it can from internal combustion, with a focus on how the engine breathes in and out.

That’s achieved through the fitment of the company’s own downpipes with 200-cell sports catalysts, a Deeptone exhaust, higher-performance intercoolers, and an Eventuri carbon air intake. There’s also a GP-1000 software update. We haven’t heard it yet, but those intake and exhaust modifications are sure to add some acoustic entertainment to the proceedings.

Opting for the full 999 horsepower will set you around €35,000 or $41,160, but G-Power offers its G90 M5 upgrades in a number of stages. The new software delivers 850 PS (838 hp), then to see incremental 50-hp increases, you can add the sports silencer, downpipes, and then the whole kit and caboodle, including a 155 mph top-speed limiter delete.

G-Power hasn’t said what that top speed might be, nor made any other performance claims, as a matter of fact. A factory-spec M5 will accelerate from zero-to-62 mph in a scant 3.5 seconds, taking 10.9 seconds to reach 124 mph, and, with over 250 hp more than stock, the modded car should be significantly swifter.

The upgrades are available for both the M5 sedan and the long-roof Touring. Should you wish to advertise your M5’s extra oomph, G-Power offers a decal kit, while it can also add some color to the cabin with a leather and Alcantara re-trim.
