The CLA 45 AMG Shooting Brake comes with the variable, performance-oriented AMG 4MATIC all-wheel drive as standard. In developing this all-wheel drive, the focus was firmly on performance and dynamism. The power flux to the rear powertrain is provided by a compact power take-off unit (PTU) which is fully integrated in the 7-speed sports transmission. It does not possess an oil circuit of its own. Instead, it is supplied with lubricant from the oil circuit of the sports transmission.
This configuration gives rise to substantial weight advantages in comparison to rival systems which branch off power by means of an add-on component with its own oil circuit. Together with the friction-minimized tapered roller bearings, the PTU achieves an excellent level of efficiency. As an additional bonus, the system weight of the new AMG 4MATIC all-wheel drive is up to 25 percent lighter than the all-wheel-drive versions offered by the competition.
