The F20 (5-door) and F21 (3-door) BMW M135i remains one of the most celebrated rear-wheel-drive hot hatches ever produced. Powered by the potent 3.0-litre turbocharged N55 inline-six engine and paired with either an engaging 6-speed manual or a rapid 8-speed ZF8 automatic transmission, this platform delivers unmatched straight-line punch and dynamic driving engagement. JXL Performance is your ultimate hub for premium tuning hardware to push this N55 platform to its absolute limits.
