Last week we brought you less disguised spy shots of the upcoming Mercedes-Benz AMG GT / SLC, cold weather testing near the Arctic Circle.
Here we have new pictures showing a second prototype of the AMG GT. At first it looks identical to the one we saw last week, but when you look at the rear, you will notice different exhaust tips.
This most likely means there are two engines currently being tested. Different sources have mentioned a 4.0-litre twin-turbo V8 and a 5.5-litre twin-turbo V8 linked to seven-speed SPEEDSHIFT dual-clutch gearbox. These two engines are expected to produce between 450-550bhp.
As it was quite dark outside we also get to see little of the taillight graphics and the brake light on the rear window.
A range topping Black Series is also very likely to follow later with around 600bhp.
