Overview
German tuner G-Power has once again taken the latest-generation BMW M3 and turned it into an uncompromising performance sedan. The conversion is not just visual: the car packs a series of engine upgrades that push outputs into supercar territory, making the M3 CS look relatively subdued. This article breaks down the performance packages, specs, styling options, and market positioning for enthusiasts considering a G-Power M3 build.
Performance Upgrades
At the top of G-Power's offering sits a headline figure of 700 horsepower, which converts roughly to 690 bhp and 515 kW. Torque is listed at 627 lb-ft (850 Nm). With G-Power's engine modifications and calibration, the tuner claims a top speed of 193 mph (310 kph) — staggering for a four-door sports sedan. These upgrades transform the M3 into a true high-speed contender on both road and track.
Available Power Packages and Pricing
- Top package: 700 hp (approx. 690 bhp / 515 kW) and 627 lb-ft (850 Nm) — top speed 193 mph (310 kph). Price: €16,447 (approx. $19,100 in Germany).
- Mid package: 641 hp (650 PS / 478 kW) and 590 lb-ft (800 Nm). Price: €12,634 (approx. $14,670).
- Entry stage: 592 hp (600 PS / 441 kW) and 553 lb-ft (750 Nm). Price: €3,685 (approx. $4,280).
Those packages give buyers a clear ladder of performance upgrades so they can match budget to ambition.
Design and Aerodynamics
G-Power’s visual packages reinforce the car’s aggressive stance. Typical offerings include carbon fiber hoods, rear wings, specialized front splitters, side skirts, and rear diffusers to improve airflow and give the M3 a more purposeful look. Combined with a selection of motorsport-style wheels and lowered suspension, the car’s handling and aerodynamic stability are also enhanced.

Aftermarket Parts and Customization
Beyond engine tuning and aero, G-Power lists a long catalog of bolt-on parts: high-performance exhaust systems, engine covers, decals, bespoke steering wheels and paddle shifters, sport suspension components, reupholstery options, and tailor-made floor mats. These parts enable buyers to create a truly personalized performance sedan that looks the part and sounds aggressive.
Vehicle Specifications: Factory vs Tuned
Factory BMW M3 outputs vary depending on trim: the latest M3 is offered with approximately 473 hp (480 PS / 353 kW), 503 hp (510 PS / 375 kW), or 523 hp (530 PS / 390 kW). G-Power’s upgrades take even the highest factory spec well beyond OEM figures and into performance that rivals many supercars.
Stock performance benchmarks
For context, the 2026 BMW M3 starts at $78,400. The M3 Competition begins at $82,600, while the M3 Competition xDrive is priced from $87,700, excluding destination and dealer fees. The xDrive Competition accelerates from 0-60 mph in about 3.4 seconds — notably faster than the non-xDrive variants.

Market Positioning and Comparisons
After tuning, the M3 shifts from a premium compact sports sedan into a high-powered contender that competes with exotic and near-supercar machines in straight-line speed and track performance. While the M3 CS is designed to be an extreme factory variant, G-Power’s top build makes the CS appear conservative by comparison — especially in top speed and torque figures.
Who Should Buy a G-Power M3?
Enthusiasts seeking dramatic performance gains, exclusive styling, and bespoke aftermarket options will find these G-Power packages attractive. However, buyers should weigh the implications for warranty, insurance, and daily drivability when moving beyond milder upgrades.
Final Thoughts
G-Power’s tuned BMW M3 is a clear statement: with the right upgrades, a four-door sedan can rival exotic machinery. Whether you prioritize top-tier horsepower, track-capable handling upgrades, or a standout aesthetic, the G-Power M3 offers a comprehensive set of options to transform the M3 into a high-performance, head-turning machine.
