At the heart of every M car is the engine. The X5 M Competition uses a high-performance 4.4 litre M TwinPower Turbo 8-cylinder petrol engine, delivering 625hp and 750Nm of torque and hitting 0 to 62mph in just 3.8 seconds. Equipped with two twin scroll turbochargers, high-pressure injection and Valvetronic, you have the most powerful engine to feature in a BMW standard production vehicle.The M Sport exhaust system, with quad exhaust pipes, can be sound optimised through a centre console button. The SPORT and SPORT+ modes can deliver an even more intense engine sound, while the comfort-orientated programme offers a quieter experience.
