Work continues on the Mercedes A-Class sedan as spy photographers have caught the upcoming model undergoing testing on the Nürburgring.

Dressed in black and white camouflage, the entry-level sedan follows in the footsteps of the redesigned hatchback as it adopts a familiar front fascia with a single bar grille and CLS-inspired headlights. The styling similarities continue further back as the sedan has an upward sweeping beltline and subtle character lines.

Of course, the biggest change is the sedan body style which mimics the larger C-Class. However, due to the smaller dimensions, the car has shorter rear doors and a small trunk with an integrated spoiler.

Inside, we can expect a high-tech cabin that echoes the new A-hatchback. As a result, drivers can expect to find a three-spokesteering wheel, circular air vents and plenty of metallic trim. The model should also have new Mercedes-Benz User Experience (MBUX) with two displays that measure 7- or 10.25-inches.

Engine options should also carryover from the hatchback and include an assortment of petrol and diesel options. On the petrol side, we can expect an A200 with a 1.33-liter four-cylinder engine producing 163 PS (120 kW) and 250 Nm (184 lb-ft) of torque. Buyers should also be able to order an A250 which has a 2.0-liter four-cylinder engine developing 224 PS (165 kW) and 350 Nm (258 lb-ft) of torque.

Diesel fans should have the option of a 1.4-liter four-cylinder producing 116 PS (85 kW) and 260 Nm (191 lb-ft) of torque. It enables the hatchback to run from 0-100 km/h (0-62 mph) in 10.5 seconds before hitting a top speed of 202 km/h (125 km/h).

Further down the road, we can expect the Mercedes-AMG A35 with a turbocharged 2.0-liter four-cylinder engine featuring EQ Boost technology. This setup should enable the model to produce around 299 PS (220 kW) and 400 Nm (295 lb-ft) of torque. There should also be an A45 with around 400 PS (295 kW)
