New M4 vs RS5 vs C63s
I had both cars. From 01/2015 until 10/2018 the M4 with original 431hp. From 03/2019 until 10/2020 the C63S with original 510hp.
In my opinion the M4 is clear the better car. The M4 is a real race car. Its very fast on a track and not so heavy like the C63.
The C63 lives only from the V8 Motor with this increadable sound. That was also the reason for me why i bought it. I want drive a V8 before they are gone.
I never loved the C63. I dont like the design as much as from the M4 but the interior from the 2019 C63 was more modern that the M4.
I put on both cars the JB4. In the M4 with Downpipes and in the C63 without downpipes because to complicated with removing gearbox etc.
With this tune the M4 was the faster car. I drove 100-200kmh in 7.5s with the M4 and 7.9s with the C63. The C63 has a slight better traction. Maybe because of more weight on the rear.
But both cars have problems to get the power on the road. For that the new M4 with all wheel drive and possibility to switch on rear drive for drifting will be great.
The consumption was a big big difference. I would say the C63 need 3-4L more at 100km.
After 3 Month owning the C63 i tougth damn why i didn't take a M4 competition after my M4 (it was an option to the C63) because when i bought 2015 my M4 there was no comp available.
If someone asks me i say if you like the sound of the M4 take the M4. If you wannt drive a V8 with an amazing V8 sound take the C63.
I thought the C63 will die when the Motor will switch to 4 or 6 cylinders because of everyone will take the M4. (In my opinion the F8X M4 is one of the beautifull car ever)
But now I dont think so because BMW make the new M4 not so beutifull design.
Both cars are great and its like a question about the taste.
