Numbers can be fascinating: just take the 550i's eight-cylinder petrol engine. Its vital statistics are 270 kW at 6,300 rpm, zero to 100 km/h in 5.4 seconds and 11.3 litres per 100 km. What's more, this Valvetronic-equipped V8 delivers outstanding pulling power throughout the rev range, with more than 80% of its peak torque available from as early as 1,500 and staying online right up to 6,300 rpm. It all adds up to 100% driving enjoyment.
