Our spies have managed to snap new pictures of the Mercedes B-Class AMG undergoing cold weather testing in Scandinavia.

Lightly camouflaged, the prototype appears to have a revised front fascia, a dual exhaust system and five-spoke wheels that cover high-performance brakes. We can also expect a sport-tuned suspension for improved handling.

While rumors have suggested the prototype is just a test mule for the upcoming A- and CLC-Class AMG, other sources indicate the B-Class AMG could be launched sometime next year.

Regardless, all the entry-level AMGs are expected to use a turbocharged 2.0-liter petrol engine that develops 320 hp (239 kW / 324 PS) to 350 hp (261 kW / 355 PS). It will likely be connected to a dual-clutch transmission which sends power to an all-wheel drive system.
