According to this Aussie article, the W206 C63 is expected to have (translated from kW and NM) 550 hp and 590 ft-lb torque. That's significantly more than the G8x Competition model. But what really stands out is the weight is going to be around 4,400 lbs (2,000 kg). That's about 500 lbs heavier than the G80 that was already criticized to be too heavy!

If all this is true, then it's not the sound that's the major issue (the M139 in the A45S sounds not great but still OK), but rather the hefty weight.

Nothing like a 100k 4 cylinder........

[M3_WC]

Oh great. We now have an ugly pig nose M3/M4 and a 4-cylinder C63. Fan-f*cking-tastic.

[Fined]

I've thought of what I'll do when I need a more adult car than my M2.. been eyeing the C63 AMG for years.. may I'll end up getting one of the last run from 2020 here in a few years if I have a strategy for keeping the navigation updated.

C63 AMG 4 cylinder I do not think I'd want.

[P1]

What on earth is the point of buying a "63" AMG when you don't get the best thing about them: that V8 and arguable some of the best stock exhaust notes out there.

Horrendous decision.

[dtwyim]

Porsche 718 came out as a 4 pot and now added back the flat 6 to the higher trims.

MB might do the same.

Wait for the C63S.

Agree loss of sound and V8 is a major turn off.

I drive the car, not the numbers.

Drive any 4 cylinder engine and compare it to an inline 6 or V8 from the same manufacturer and it might produce the same hp but every other sensation from the sound, to smoothness, to powerband is a step down.

Personally think the ICE trend is making EVs look better and better. Then with an EV everyone's is silent, smooth and fast enough, not seeing the powertrain characteristics mattering regardless of the manufacturer. Can BMW make a better electric motor than Ford?

Exactly, I couldn't care less about the hp and torque if it's got the character of a 4 cylinder. Might not be so bad on a hot hatch because you really don't have a choice, but on anything else, no thanks.

I find it intriguing that they didn't use the PHEV system with the Inline 6. Have never driven it, but I've heard nothing but great things about it. That would have at least cushioned the blow of losing the V8, which was inevitable. I really question this decision.

I'd be open to PHEV's over a full electric car, but the engine itself still has to be something I want.

So does this mean all of their larger sport utility vehicles that have the "63" variant are going 4 cyl as well? There's going to be a longer list of people that won't go over well with.

It seems that E-Class and up are keeping the V8. New S, SL, GT, etc are getting electrified V8's while they still can. They will be getting the 4-pot in lower trims possibly (for the SL/GT).

Seems so stupid. It's not like the engine is going away, and the 63 is low volume vehicle. Should have just kept it in there.

It is stupid, but they are likely under heavy pressure due to EU emissions. They just barely escaped fines for euro CO2 targets last year after a late surge in PHEV/EV sales.

I believe your thoughts on the topic is not allowing you and a few others to actually read what I wrote. I said calling the worlds most powerful production 4 "basic" is unfair. This is independent of the thread topic. I feel a more accurate statement would be while this motor is very impressive for what it is, it does not belong under this model designation.

Piecing together rumors of various future Mercedes vehicles (such as the W206 C Class, R232 SL, new W223 S Class trim levels, and others) Mercedes has an absolutely dizzying array of electrified powertrain setups coming. These include mild hybrid, hybrid, and plugin hybrid versions of the M139/M254 I4, M256 I6, and M176/M177/M178 V8.

It appears that AMG PHEV models will get the "e" suffix just like non-AMG models do today, so this new C63 may actually be labeled C63e. However, there are also reports that a similar very M139 PHEV setup will adopt the 53e moniker in other upcoming models. So perhaps C53e would actually make even more sense? We'll see.

At the same time, V8 AMG models will apparently remain in the E and S families, continuing to wear the "63" nameplate, but gaining a mild-hybrid setup (and more power). Additionally there will be a "73e" PHEV V8 setup coming with upwards of 800hp. There are also reports claiming there will be a 700hp "63e" setup as well, pairing the V8 with less power electric motor, which sounds very plausible. However, the use of "63e" would seem to needlessly clash with the C63e, if indeed it will go by that name.

I've seen claims that the W206 was not designed to accommodate the I6 at all. It's a bit sketchy given that the car shares the MRA2 platform with the new S Class (and a number of other future Mercedes models), and it also retains the long hood, short trunk proportions. Still, it is obviously the smallest of the bunch, and one possible way to decrease size is by making the engine compartment a little smaller. With no plans for larger engines, this might be the route they took.

Please expand on what this "character" is?

Indeed. This is the trend and the following gens will not know what a V8 / V10 / V12 sound like. I understand the need to improve on emissions and this is the way to do it, but these cars will become too porky because of batteries and the tech behind them. I plan on keeping my ICEs

NVH - Noise, vibration, harshness as well as powerband, what it sounds and feels like at idle, partial throttle and 6500 rpm and hopefully 7000 rpm. Manufacturers do their best to isolate the engine from the driver and then manufacture fake sounds but it is a band aid at best. Try to find the best sounding 4 cylinder turbo made today and I think most would say it's still a disappointment.

MB has one of the best turbo 4's but it doesn't come close to comparing with the above with their V8 or a good inline 6, even a V6. While they are under pressure to produce lower CO2, I don't understand why their current engine couldn't have carried over in low volumes or how they expect to sell it while BMW, Alfa, (even Cadillac here), continue to offer vehicles that to me have far superior enthusiast power plants.

I also think this car will gain a lot of weight.

With the EU system I think it is corporate average CO2? Why can't Ferrari include a small EV with each 488 and their average mpg would be about 70 mpg? Ferrari owner would immediately sell the EV and like most Ferrari's rarely drive his 488. Actual overall CO2 for the two cars would be very close to the EV.

Might as well go full EV.
Hybrid 4cyl in a performance car is garbage and maintenance will be a nightmare long term or if u track it.

I would run and get the V8 C63amg.
