A Mercedes AMG C-Class without a V-8 would have been considered unthinkable ten years ago. Back then, the 6.2-liter V-8, which had one of the best exhaust soundtracks since the turn of the century, was dropped in nearly every AMG model in production. This meant that the German car industry was awash with glorious rumbles, snorts, growls, and bellows from Merc's handcrafted naturally aspirated V-8. Then, by 2016 the current-generation C-Class was in full production with a 4.0-liter twin-turbo V-8 that was more efficient and powerful than the old 6.2 but lacked some noise and character.

What about the new one though?

Now, the 4.0-liter AMG C-Class is coming to an end, and it is fair to say not many people are extremely excited about the new one and its hybrid 2.0-liter four-cylinder turbo. Even though the new powertrain will make it the most powerful AMG C-Class and the most efficient, it is failing to stir the emotions of enthusiasts, at least before anyone can drive it.

Based on the video itself, the new AMG C-Class looks more than composed going around the Nurburgring's many corners with little to no body roll. There also appears to be rather late braking for corners which leads us to believe Mercedes may have been testing new carbon ceramic brakes. Granted there is no way to know just how fast the car was moving.

Of course, there is the sound. For a good bit of the video, there is little to no exhaust note whatsoever, and when there is, it is nothing too noteworthy. If Mercedes was going to use such a mildly mannered engine, the least they could do is throw on a sportier exhaust. Why not just straight pipe it?

In terms of what this new dreaded engine is actually like, we know it is the 416 horsepower M139 engine from the AMG A45. Except its peak power figure will grow to 470 horsepower, as well as being mounted longitudinally. This wild four-pot will be working in tandem with a 200-horsepower electric motor mounted on the rear axle. That's right, the AMG C-Class will be capable of about 670 horsepower and 553 pound-feet of torque.

That is in contrast to its predecessor's 503 horsepower and 516 pound-feet of torque. In fact, it makes the 6.2-liter engine of yesteryear look rather flimsy with a peak horsepower output of 507 and 450 pound-feet of torque.

In terms of the styling, the model had camouflage plastered on the front and rear bumpers but expect the same panamericana grill that has been featured on other AMG Mercs of recent years. You can also make out the traditional four-exit exhaust, a big rear-diffuser, and possibly a front splitter.

We know this will be the fastest and most advanced AMG C-Class ever, lets hope it is one of the most exciting as well.
