First-ever three-box A-Class to kick off from $44,900, with a staggered launch planned for the four Oz-bound variants.

Mercedes-Benz Australia has detailed the all-new A-Class Sedan range, joining the hatchback Down Under.

At launch, just two variants will be on sale, with two more versions to arrive before the end of the year.

The A180 is priced from $44,900 plus on-road costs, and will arrive here in August. Meanwhile, the A200 kicks off at $49,400 before ORCs, and is on sale now. Both command a bit over $2000 compared to the equivalent A-Class hatchback.

Specification mirrors that of the related hatchback, meaning the dual 10.25-inch MBUX infotainment unit is standard, as is satellite navigation, 'Comfort' seats finished in 'Artico' leatherette upholstery, front and rear parking sensors, electric folding side mirrors, DAB+ digital radio, 225W nine-speaker audio, 17-inch five-spoke alloys, climate control, Apple CarPlay and Android Auto, a three-spoke sports steering wheel, keyless start, and selectable drive modes.

In terms of active safety and driver assist tech, the A-Class Sedan range is equipped with active park assist, active lane keep assist, active brake assist, traffic sign assist, blind-spot assist, rear-view camera, and the Pre-Safe accident anticipatory system.

The A-Class Sedan gets a 430L boot (60L up on the hatch), while its aerodynamic efficiency figure of 0.22cd is the lowest ever recorder for a passenger vehicle, according to the German marque.

Power in the A180 comes from a 1.3-litre turbocharged four-cylinder petrol engine making 100kW and 200Nm, sent to the front wheels via a seven-speed dual-clutch automatic. Combined fuel consumption is rated at 5.7L/100km combined.

Stepping up to the A200 adds larger 18-inch alloys, the 'Progressive' styling package for the exterior and interior, chrome-tipped dual exhaust, four-way electro-pneumatic lumbar support for the driver, a folding rear centre armrest, adaptive high-beam assist, and wireless smartphone charging.

A more powerful version of the 1.3-litre turbo also lives under the bonnet, making 120kW and 250Nm. Like the A180, drive is sent to the front axle via a seven-speed DCT, while fuel consumption continues to be rated at 5.7L/100km on the combined cycle.

Following the launch of the A180 and A200 sedans, the A250 and AMG A35 sedan models will also join the line-up before the end of 2019.

The A180 arrives in August, with the A200 in dealerships now. (Overseas model pictured)
