BMW M340i — VIN Lookup & Specifications

The Ultimate Driving Machine, Elevated

BMW's M division has spent over four decades developing the brand's most performance-focused vehicles, and the BMW M340i reflects that engineering discipline in full. Compared to its standard counterpart, the M variant typically receives a substantially reworked engine, a retuned chassis with stiffer suspension and recalibrated steering, larger brakes, and aerodynamic elements developed specifically for high-speed stability. M models are engineered and validated extensively at the Nürburgring, a process that shows in the precision of their on-limit behavior. The M340i represents BMW's clearest statement about what a driver-focused performance vehicle should deliver.
