The estate version of the A45 S 4Matic+ hyper hatch is available to order in the UK now, priced from £53,370 - a £3000 premium over the hatchback. Standard equipment, as with the hatch and coupé, includes 19in five-spoke alloys, keyless entry, heated front seats, a performance steering wheel and a pair of 10.25in screens. Range-topping Plus trim adds a downforce-enhancing aero package, multibeam LED headlights, forged alloy wheels and leather upholstery.
A development of the first-generation’s M133 unit, the new M139 2.0-litre turbo engine will be offered in two states of tune.
The UK will only offer the more powerful iteration, the range-topping CLA 45 S 4Matic+ Shooting Brake. It develops 39bhp and 18lb ft more than its predecessor at a class-leading 415bhp and 369lb ft.
As with the A45 4Matic and CLA 45 4Matic, drive is channelled through an eight-speed dual-clutch automatic gearbox, with shift paddles mounted on the steering wheel. A reconfigured Haldex-style multi-plate-clutch four-wheel-drive system features a Torque Control mechanism that uses two clutches to apportion power individually to each rear wheel.
The changes to the four-wheel-drive system have allowed AMG to give the new model a Drift mode function. It’s accessed through a revised Dynamic Select system that offers up to six driving modes, including Slippery, Comfort, Sport, Sport+ and Race.
