BMW M5 Hybrid Review: Speed vs Driving Dynamics Dilemma

content: The Heavyweight Performance Contender

After driving BMW's new plug-in hybrid M5 back-to-back with its predecessor, I've reached a concerning conclusion. This M5 delivers staggering straight-line speed at the cost of traditional M-car agility. With 717 horsepower and 738 lb-ft torque from its turbocharged V8 and electric motor combination, it's BMW's most powerful production car ever. But during aggressive cornering, you feel every pound of its 5,390-lb curb weight. The critical question for enthusiasts: does this technological marvel still deliver authentic M Division driving thrills?

Performance Benchmarks and Real-World Testing

Acceleration is unquestionably brutal. Our instrumented testing confirmed 0-60 mph in 3.1 seconds - a tangible improvement over the previous F90 model. During roll races, the instant electric torque provides a decisive advantage. However, the ZF 8-speed transmission prioritizes refinement over aggression, muttering shifts rather than delivering the snappy engagement expected in an M car.

The hybrid system integration deserves praise. Unlike some plug-in hybrids, there's no brake pedal weirdness or power delivery jerkiness. BMW's calibration makes the transition between power sources nearly invisible during normal driving. You can customize the hybrid behavior extensively through the M Hybrid menu, though the interface complexity becomes overwhelming.

Handling Compromises Revealed

The weight penalty manifests dramatically in corners. Despite rear-wheel steering and a quick steering ratio, the G90 generation heaves through direction changes. Back-to-back testing revealed noticeable understeer compared to the F90, even on the optional Michelin Pilot Sport S5 tires. While the two-wheel drive mode enables dramatic drifts, the fundamental agility that made previous M5s "autobahn assassins" feels diminished.

BMW's chassis engineers clearly fought a battle against physics. The standard adaptive suspension does an admirable job managing body motions, but you're always aware of the mass. This contrasts sharply with the F90's surprising nimbleness - a car that felt like a scaled-up M3 in spirited driving.

Design and Interior Realities

Visually, BMW embraces the M5's substantial proportions with flared wheel arches and body-colored surfaces. Our Daytona Violet Metallic test car looked imposing but lacked the elegant proportions of its predecessor. The controversial front grille treatment leans toward EV styling cues, further distancing it from traditional M design language.

Inside, the M-specific seats are exceptional - comfortably bolstered for a car of this size. But material quality shows cost-cutting versus the previous generation. Missing stitching on door panels and dashboard surfaces creates a less premium environment. The curved display running BMW Operating System 8.5 is technologically impressive but adds complexity. Managing drive modes now requires navigating through four separate menus (M Setup, M Hybrid, M Mode, and Electric settings).

The M5 Identity Crisis

This generation represents a fundamental shift in philosophy. Where past M5s balanced executive comfort with track-capable dynamics, the G90 prioritizes straight-line performance and regulatory compliance. The plug-in hybrid system enables 40 km of electric range and avoids punitive emissions taxes, but adds 1,000+ lbs versus the F90.

BMW loyalists face a difficult choice. The new M5 delivers unprecedented acceleration and cutting-edge tech, but sacrifices the tactile feedback and balance that defined the M legacy. For daily commuting and highway blasts, it's phenomenally capable. For driving enthusiasts seeking involvement, it feels like a compromise.

Practical Considerations

• Rear seat comfort remains excellent with generous legroom, though headroom is tight for passengers over 6'4"
• Trunk space is surprisingly usable despite the hybrid battery, a significant engineering achievement
• Standard carbon roof helps lower center of gravity, partially mitigating the weight penalty
• Lack of bucket seat option reinforces the car's grand touring orientation

Verdict: Technological Triumph, Driver's Compromise

After extensive testing, I believe BMW has created two distinct M5 lineages. The new hybrid model delivers astonishing acceleration and commendable daily usability, while the previous generation remains the purist's choice for driving engagement.

This isn't an evolution - it's a redefinition. The M5 now competes directly with heavyweight performance hybrids like the Porsche Panamera Turbo S E-Hybrid rather than lighter sports sedans. Whether this trade-off succeeds depends entirely on your priorities. If straight-line speed and tech supremacy outweigh cornering finesse, this M5 delivers. If you cherish steering feedback and agility, the F90 remains the benchmark.

3 Critical Test Drives Before Buying

1. Back-to-back comparison: Drive the G90 immediately after an F90 to experience the handling differences
2. Cornering stress test: Find a winding road to evaluate body control and steering feedback
3. Hybrid functionality check: Verify the electric range meets your commute needs and test charging logistics
