The aftermarket specialists are currently working on a power upgrade for the 2.0-liter four-cylinder turbo engine which in its standard configuration delivers 360 HP (265 kW) and 450 Nm (332 lb-ft) of torque. The smallest AMG model ever needs 4.6 seconds to reach 62 mph (100 km/h) before topping out at an electronically-capped 155 mph (250 km/h).
