Contrary to what most marketing tells us, progress is not always forward. Sometimes a product nails the balance of what consumers want so perfectly that it's nearly impossible to improve on it – just compare the original Ford Mustang to the atrocious Mustang 2. Drive's Chris Harris is worried the same fate is about to befall the Mercedes-Benz C63 AMG, which he reckons is at the top of the heap of German sport sedans.

The next-generation, AMG-tuned C-Class is rumored to use a 4.0-liter, turbocharged V8 with between 450 horsepower and 500 hp to replace the C63 AMG's legendary M156 6.2-liter V8 with 451 hp and 443 pound-feet of torque. Even Harris admits that the new engine will likely improve on the C63's dismal fuel economy, but he doesn't believe that it will drive any better. And if the E63 AMG's downsized M157 5.5-liter V8 engine is any indication, it certainly won't sound any better, either.

Scroll down to watch Harris slide the even more powerful C63 AMG Edition 507 wagon while giving it a proper eulogy.

      To me, there is no engine better than the M156. I've got one in my current DD and I love it to death. It sounds incredible, it has an amazingly tractable powerband, it is smooth and civilized when you want it to be and is bulletproof reliable.

      It will be a sad day indeed when the final one is built. It might drink fuel like its going out of style, but when you crack the throttle open, you don't give a ****.

      I owned a C63 sedan and I must admit, it was the most fun and amazing car I've ever had. The power and sound is flat out addictive. It's unassuming to the untrained eye so guys in rice burners were constantly trying to give me a run (bad idea on their part). Unfortunately due to its love for Premium Octane and rear tires (new ones at least every 10k), I had to move on to something far less powerful and more efficient when I switched to a job that required me to drive everywhere. I miss that car every day when I climb into my slow but fuel efficient daily driver. That car is like that beautiful bombshell you dated for a while, she'll leave you breathless but when she's gone you yearn for her every day.

      Thing of beauty. What a glorious sounding engine wrapped in such smart packaging. Everything about this is so right (outside of MPG). Power numbers are mostly academic in comparison with the upcoming version. This engines delivery seems to have smitten most enthusiast/journalists. Wish i could wring one out to confirm their opinion...

        I know a guy who bought this car for its engine power and sound alone. He says "it's really addictive" .

      The world needs more fast wagons. And just more wagons in general. I salute this car.

        So Cool! Congrats! The 6.2 in the Merc might be the greatest V8 of all time. I can only dream. I have to make due with the occasional passerby and youtube videos. Give it hell for me!

          Thanks a lot guys! You can't even imagine the excitement I'm holding within for this beast! Yes, one of the main reason that pushed me to pick this car over its rivals was that monstrous M156 na V8. Test drove the '13 C63 last year (non-performance package) and it blew my mind. My wife kept saying me I couldn't stop smiling hours after driving it. Lol Can't wait!! XD

      So it will pump the same or higher peak power, likely have higher low end torque, all while using less fuel, and yet the author states, "progress is not always forward." His problem is that it might not drive any better, meaning what, that the new engine won't improve handling? His other problem is the sound? Give me a break. Stop whining. The smaller turbo engine is all around better. Same power with less fuel consumption. It will keep more of it's power at higher elevations and will be easier to tune for even more power.

        Given a choice, I prefer a naturally aspirated engine. Power output is more linear. That is, when you press the accelerator you get the amount of power that you expect. Often with turbocharged engines you tend to get less or more than you expect. And the noise of the AMG 6.2 is just glorious. Turbos muffle that great sound. Turbocharged engines are the wave of the future as EPA regs get tighter, but I'll miss the AMG 6.2.

        N/A 6.2 tops a measly 4.0 turbo.

        I agree with you. Car writers aren't car consumers. They don't have to live in the real world.

        HP from boost is never as responsive as HP from displacement. Sure the figures are nice to look at, but how many new cars that are supposed to be so great and wonderful turn out to be paper tigers? I love tuner cars like the old Skylines and the 350/370Z, but I will be the first to tell you that there is no true replacement for displacement.

          It's about the feel of the power delivery-a NA engine will always feel better than turbo in a non-quantitative sense.

          Manual or paddles are essential to high-strung turbos. Then they can be kept in their power band and exploited to the fullest.

        Yeah, really looking forward to pulling the head every 60-80k miles and cleaning the carbon buildup on a direct-injection, turbo engine. And the head gaskets, and the turbo rebuilds, and all the other added maintenance and wear/tear items that you don't on a naturally aspirated port injection engine...better in many areas, but not long term maintenance costs.

        I know what you mean. But this is really about the pure performance aspect of the old NA engine (responsive, lightweight, great sound) vs. the new turbo engine (turbo lag, more weight, muted sound). However the new motor is a step in the right direction.
