In our latest batch of spy photos from Europe, we're getting alook at aprototypeof the upcoming Mercedes-AMG GLC 63 SUV.

Almost everymodel in the Mercedes-Benz lineup has either an AMG or an AMG-Sport model in it, so we'renot surprised to see images of a GLC 63 prototype undergoing testing. The images reveal thelarge trademarkgrille on the front of this mule, which is a suresign of a monster engine lurking beneath the hood. As for engines, well there's a wide selection of high-power engines at AMG's disposal.

Remember that the badge on the rear no longer refers to engine capacity, so while it carries a 63 badge, there may not be a 6.2-litre inside. Reports suggest that AMG has opted forthe 4.0-litre biturboengine used in the AMG GT and Mercedes-AMG C63. This engine is surprisingly compact thanks to the positioning of both turbochargers within the two banks of cylinders.

We will likely see two GLC 63 derivatives on offer including a standard version with no less than 350 kW and 650 Nm of torque, as well as a GLC 63 S with 375 kW and 700 Nm of torque.

You can expect the GLC 63to feature 4Matic all-wheel drive,which will give it an estimated 0-100 kph sprint time of about 4.5 seconds. The GLC 63 and its coupe sibling are on course for launch in 2017.
