BMW M4 vs. Porsche 911

While Porsche’s flat-six puts out a respectable 331 lb-ft of torque, the M4 Competition ups the ante with a hefty 479 lb-ft, ensuring stronger midrange pull—ideal for passing on the highway or powering out of tight corners. And for purists, BMW still offers a 6-speed manual in the standard M4 (473 horsepower), whereas the 911 Carrera T’s 6-speed comes only on the niche T model and costs a premium.

Adaptive M Suspension on the M4 continuously adjusts damping for optimal grip and comfort—something Porsche’s fixed-rate PDK setup can’t match on the fly. BMW’s M Sport Differential further sharpens turn-in by distributing torque between the rear wheels, whereas the 911 relies on a more traditional mechanical LSD.

Visually, the M4’s carbon-fiber roof and optional M Carbon Exterior Package give it a purposeful, aggressive stance—complete with mirror caps, rear spoiler, and diffuser inserts. The Porsche 911 remains timelessly elegant, but the M4’s bold kidney grille and high-gloss black accents make a more modern performance statement.

Practicality often gets overlooked in the super-coupe segment, yet the M4 offers 15.5 cubic feet of trunk space—more than three times the Porsche 911’s 4.8 cubic feet. That means groceries, golf clubs, or a weekend’s worth of luggage won’t be an afterthought. Inside, BMW’s Curved Display with Operating System 8.5 and the BMW Intelligent Personal Assistant keep tech at your fingertips. At the same time, Porsche’s new fully digital dash is crisp but less intuitive when operating on the move.

The M4 isn’t just about straight-line speed. Variable Sport Steering and the optional M Carbon Bucket Seats put you firmly in command. At the same time, BMW’s M Mode customizes throttle response, damping, and even the instrument cluster display to your driving style. Porsche’s legendary chassis is sublime, but the M4’s combination of adjustable dynamics and driver-focused ergonomics makes every twisty backroad feel like your personal racetrack.
