The 2025 BMW M135 xDrive (F70) is the flagship of BMW’s compact 1 Series lineup, delivering a potent blend of performance, technology, and premium appeal in the hot hatch segment. Powered by a 2.0-litre TwinPower Turbo four-cylinder engine (B48), it produces 296 hp and 400 Nm of torque, achieving 0-62 mph in 4.9 seconds with a 155 mph top speed. Mated to a new seven-speed dual-clutch transmission and xDrive all-wheel drive, it offers sharp responses and excellent traction, enhanced by a front mechanical differential lock and stiffer anti-roll bars. The Adaptive M Chassis, with its lowered suspension and precise steering, ensures agile handling. Fuel economy stands at 34–37.2 mpg (WLTP), with CO2 emissions of 173–188 g/km, balancing performance with efficiency for UK drivers.
