We drive the latest from BMW - the powerful and blisteringly fast M8 Coupé and Convertible, and too too in the slightly more potent Competition variant. The car is the epitome of engineering at BMW and now becomes a flagship model for the M Division too. Over 600 horses, 750 Nm of torque and a delightful M suspension, gearbox and steering make for an engaging drive. We test the car on the twisty country roads of southern Portugal, and also on the very fast Portimao circuit. BMW also launched the 8 Series family alongside the M8 - in the form of the 8 Series Gran Coupe. To watch that review, click here.
