Clever engineers have squeezed an astonishing 265 kilowatts of power and 450 Nm of torque from a little 2.0-litre engine for the CLA45 AMG. The high-pressure petrol turbocharged engine is the most powerful four-cylinder mass production engine ever made, and is married to a seven-speed dual-clutch automated manual gearbox muscled up to deliver uber-fast shifts.
The all-wheel drive system feeds torque mainly to the front wheels under normal conditions, with the rear ones coming into play in just a tenth of a second when needed.
