The 2025 BMW M3 3.0 BiTurbo Competition Steptronic M xDrive is a high-performance saloon tailored for the UK market, combining blistering speed, agile handling, and premium refinement. Powered by a 3.0-litre twin-turbocharged inline-six S58 engine, it delivers 530 bhp (390 kW) at 6,250 rpm and 650 Nm of torque from 2,750-5,730 rpm. Paired with an 8-speed M Steptronic automatic transmission and M xDrive all-wheel drive, it accelerates from 0-62 mph in 3.5 seconds (0-60 mph in 3.4 seconds) and reaches an electronically limited top speed of 155 mph (or 180 mph with the optional M Driver’s Package). Fuel economy is rated at 27.7-28.0 mpg (WLTP), with CO2 emissions of 227-230 g/km, meeting Euro 6e standards. Externally, the M3 Competition xDrive boasts a bold, muscular design with a 4.79-metre length, 1.90-metre width, and a low 1.44-metre height. The M Sport aesthetic includes a large, frameless kidney grille, adaptive LED headlights with matrix high-beam, and 19-inch front/20-inch rear M double-spoke forged alloy wheels (style 825M or 826M). Optional M Carbon Exterior Package adds carbon-fibre elements like mirror caps and a rear spoiler, while colours like Frozen Tampa Bay Green or Yas Marina Blue enhance its striking presence. The M-specific suspension lowers the car by 10 mm for a planted stance. Inside, the cabin seats five and offers a 480-litre boot, blending luxury with performance. Standard Merino leather or optional M Alcantara/Veganza upholstery adorns M Sport seats with power adjustment, heating, and lumbar support. The BMW Curved Display combines a 12.3-inch digital driver’s cluster and a 14.9-inch touchscreen running iDrive 8.5, supporting wireless Apple CarPlay, Android Auto, and M-specific telemetry. M1/M2 steering wheel buttons allow quick access to custom drive modes, adjusting throttle, suspension, and drivetrain. Optional M Carbon bucket seats add track-focused flair but may compromise long-distance comfort.
