BMW M5 G90 vs F90: Real-World Performance, Hybrid Tech & Verdict
BMW M5 G90 vs F90: The Definitive Showdown
The moment every BMW enthusiast awaited has arrived: does the new hybrid-powered G90 M5 truly outperform the legendary F90 generation? After extensive real-world testing—including dyno runs, drag races, and weight measurements—we cut through the marketing claims. If you're weighing these performance titans or questioning BMW's hybrid shift, this evidence-based analysis delivers answers.
Performance Face-Off: Dyno Truths and Drag Strip Dominance
Dyno results don't lie. The previous F90 M5 Competition (claimed 625hp) produced 536hp on our Mustang dyno. The new G90, however, shocked us: its 727hp factory claim translated to 740hp under real testing conditions. That’s a 204hp advantage for the G90—far beyond BMW’s official numbers.
Acceleration tests proved decisive:
- 0-100 km/h: G90 achieved 3.6 seconds (vs. F90’s 4.1 seconds)
- Rolling acceleration (30-100 km/h): G90’s hybrid torque advantage crushed the F90
- Top speed: G90 unofficially hit 305+ km/h (electronically limited to 250 km/h stock)
The hybrid system’s instant torque delivery (1,000 Nm combined) gives the G90 a brutal launch. While the F90’s V8 roar is missed, the G90’s performance is objectively superior.
Hybrid Engineering: Why BMW Ditched the Pure V8
Frank van Meel, BMW M CEO, confirmed the harsh reality: "Maintaining the V8 while meeting stricter global emissions regulations was only possible with plug-in hybrid technology." This system also avoids punitive taxes in markets like Europe and China.
Technical breakdown:
- 4.4L Twin-Turbo V8: 585hp / 750 Nm alone
- Electric Motor: 177hp / 280 Nm
- Combined Output: 717hp (SAE) / 1,000 Nm
- EV-Only Mode: Up to 140 km/h for 69 km range
Driving modes matter:
- Dynamic Plus: Maximizes combined power for acceleration
- E-Control: Prioritizes gas engine to recharge batteries
- Hybrid: Balances efficiency and performance
While purists lament the muted exhaust, the tech delivers compliance without sacrificing speed.
Daily Usability: Weight, Interior & Ownership Realities
Weight is the G90’s biggest compromise. BMW claims 2,435 kg, but our scale showed 2,391.5 kg with a quarter tank. Even at this weight, carbon-ceramic brakes (optional) provide staggering stopping power. The F90, at 1,957 kg, feels noticeably lighter in corners.
Practical improvements:
- +20mm rear legroom
- 14.9" + 12.3" curved displays (all touch controls)
- Bowers & Wilkins 18-speaker audio
Key frustrations:
- Excessive piano-black trim (fingerprint magnet)
- Small exhaust tips (vs. F90’s aggressive outlets)
- Fuel economy: 10.7L/100km observed—no efficiency gain
Charging takes 3 hours on standard AC. The hybrid system recharges via driving, but expect frequent gas station visits with the 60L tank.
The Verdict: Progress with Compromises
The G90 is faster, tech-forward, and regulatory-proof. It dominates straight-line performance and offers usable EV range. However, the F90 retains advantages:
- Raw V8 soundtrack
- Sharper handling due to lower weight
- Analog driving engagement
For most buyers, the G90 is the new benchmark. It sacrifices aural drama for devastating speed and future-proofing. If emotional connection outweighs numbers, seek a low-mileage F90.
Immediate Action Steps:
- Test drive both back-to-back focusing on launch control and cornering
- Option carbon-ceramic brakes if tracking the G90
- Negotiate paint protection to avoid swirl marks on black trim
