The German magazine Auto motor und Sport has compared the first and the latest C-Class AMG generation featuring a V8 engine. The Mercedes C 43 AMG met the high-tech Mercedes-AMG C 63 S.

For all nice things, there is always an end. The 6.2 V8 AMG engine was the most powerful normal V8 aspirated in the world. Mercedes-AMG would not comply to the principle less is more, but they were forced to, due to fuel consumption and future emission regulations.

And according to the AMG tradition, the new 4.0 litre biturbo V8 engine from the Mercedes-AMG C 63 S is more powerful and louder than the old 6.2-litre normal aspirated engine from the former C 63.

Especially, the sound is absolutely fascinating and is not produced by the resonators or by the audio system. Three flaps mounted on the exhaust system produce a fascinating sound, depending on the driving program you choose. In the Sport and Sport+ programs, the sound becomes more baritonal and more intense. Sorry, BMW M3 or Audi RS4, but this time, the Grammy goes to the Mercedes-AMG.

On the other side, we have a calm story. In 1993, a discrete six inline engine was launched under the bonnet of C 36 AMG. Four years later, based on the same W202 generation, Mercedes has replaced the six in line with a V8.

Named C 43 AMG, this was the first C-Class with a V8 engine. Based on the M113 engine from the E 430, with 3 valves per cylinder and  dual spark plugs, the V8 engine got the traditional AMG treatment and the result was a power of 306 HP instead of 279 HP and a maximum torque of 410 Nm (plus 10 Nm).

With 5-speed automatic gearbox and a rear wheel drive, the C 43 AMG weight only 1,495 kg, accelerates from 0 to 100 km/h in 6.5 seconds and reaches a maximum speed limited at 250 km/h.

Although the lowered chassis with reinforced torsion bars and gas filled shock absorbers assures  a relatively firm drive train, the C 43 AMG was not really a purely sports car and the old recirculating ball steering was undecided.  On the other hand, the interior was fit at the Mercedes standard, with a fine sport touch: two tone leather, sports seats, white dials and carbon fiber imitation inserts.

Between the C 43 AMG and the modern C 63 AMG, there is an 18-year gap, but these 18 years mean the world. We talking about two different eras. In 1997, AMG had a status of being the Mercedes house tuner and worked with finished products. Today, Mercedes-AMG is a 100 % Mercedes division and works together with Mercedes from the beginning in the development process.

So, the new V4.0 litre bi-turbo V8, code name M177, was taken directly from the AMG GT with some small differences. Except the dry sump and the air filters which are placed above and not in the front of the engine, we are talking about the same engine, which develops 476 HP and 650 Nm in C 63 and 510 HP and 700 Nm in the C 63 S, due to a boost pressure of 1.2 bar. To make it clear, the C 63 S has 79 HP more than the new BMW M3.

But the power is not all. The C 63 S has an electronically controlled rear locking differential and a dynamic engine mount, plus the extra Race mode, ceramic brakes on the front axle and Cup tyres.

The new V8 is like a hammer. The press kit mentions the ”optimal responsiveness” and the ”spontaneous reactions” of the gearbox. We agree with the fast response of the engine, but the revised automatic gearbox is not as fast as we expect. But the traction impressed us just like the flow of power did.

But more power, more electronics, more safety means in the end more weight. The C 63 S weights 1,655 kg, of which 54.7% are distributed to the front wheels.  The former model only has 54% of the weight distributed to the front wheels despite the huge 6.2 liter natural aspirated engine.
