Instead, the prototypes are believed to be testing a new all-wheel drive setup and turbocharged four-cylinder engine that will appear in AMG versions of the new A Class and upcoming ‘BLS’ four-door coupe.
One clue is the makeshift exhaust pipes seen on this prototype as well as the standard rear bumper. This far ahead in development we should be seeing more production-ready items. Additionally, a peek inside shows that the standard B Class instrument gauge remains, which once again is unusual considering the prototype has been on the road for almost two years now.
Few details are known about AMG’s upcoming small car lineup, though we know the cars will come with all-wheel drive as standard. The engines, meanwhile, are likely to be four-cylinder units with turbocharging and direct-injection technologies helping it to deliver around 320 horsepower.
Previous reports have suggested that the A-Class AMG model will go by the name “A25 AMG” when it’s launched later this year. The standard A Class is scheduled to be revealed in March at the 2012 Geneva Motor Show, with the AMG version to follow later in the year.
Whether a B Class AMG is launched remains to be seen, but considering the lack of success of the previous R63 AMG Mercedes may not risk launching another high-performance MPV.
