A lot of comparisons, performed by the automotive media, are often delivering a very tight result in numerous disciplines. Most of the time there is no clear winner since advantages and disadvantages can be found on both sides.
In the case of the BMW F90 M5 Competition, which was tested by Auto Bild Sports Cars against the Mercedes-AMG GT 63S 4-Door Coupé, the picture looks slightly different. The high-performance sedan from Munich was able to beat its opponent from Affalterbach in almost every discipline.
The acceleration from a standstill to 100 km/h (0 to 62 mph) on a straight track is the most balanced figure between the two. It takes the Mercedes-AMG GT 63S 4-Door only 3.0 seconds to reach 100 km/h which is only a tenth of seconds faster than the M5.
However, the picture looks a bit different at higher speeds. After reaching 160 km/h (100 mph), the BMW M5 Competition passes the Mercedes-AMG GT 63S and is a tenth of a seconds faster at 200 km/h (124 mph). Both cars are also extremely close to each other when it comes to elasticity, with small advantages for one or the other, every now and then.
The next challenge for both high-performance cars is the German Sachsenring, a racetrack in Saxony which was opened in 1927 for the first time. A track time of 1:34.39 marks a close win for the BMW M5 Competition ahead of the Mercedes-AMG GT 63S with a time of 1:34.45. In addition, the M5 is also able to reach a higher top speed on the racetrack. To put these figures in perspective: An earlier test with the Mercedes-AMG E 63S showed a track time of 1:35.90 minutes for the Mercedes.
The lightweight concept of the BMW M GmbH plays an important role to contribute to the superior test results of the BMW M5. Thanks to 188 kg (414 pounds) lower weight, the M5 is also winning the race at the pump as it only uses 13.8 l/100 km (17 mpg) compared to 14.6 l/100 km (16.1 mpg). Even though the Mercedes-AMG GT 63S can conceal its pounds well, they naturally play a role in all driving dynamics areas. Another example is the braking power value that the BMW M5 clearly wins with a warm brake.

Mercedes-AMG GT 63 S 4MATIC+ is the fastest series production four-seater on the North Loop;Fuel consumption combined: 11.3 l/100 km, CO2 emissions combined: 257 g/km*
But although the lighter BMW M5 Competition is faster to 200 km/h, delivers a faster lap time on the Sachsenring, brakes better and consumes less, in the end, both high-performance sedans are extremely close to each other. However, maybe the price could make the difference for indecisive customers. Both, the base price as well as the price of the test car of the Mercedes-AMG GT 63S is almost 39,000 € ($44,359) higher compared to the BMW M5 Competition.
The entire test with additional data and impressions of the BMW M5 Competition and the Mercedes-AMG GT 63S is available in the current issue of Auto Bild Sports Cars. Our review of the BMW M5 can be found here.
Well done BMW M5 Competition! But clearly the Mercedes is the more beautiful looking machine. Well done to both for this generation of cars.
Clearly not. & beauty is in the eye of the beholder. How many other lesser Mercedes resemble the AMG? Have yet to see new M5, but M550i looks, sounds great.
Imagine how fast the M5 Comp would be if it had 150 Nm more torque.
Why? Pretty sure it’s more than fast enough for me now, as is.
Faster.
Where? On a track? I live in a gridlocked city of 7 million, it won’t happen on the road unless I’m trying to lose my license (nearly did that with 170 hp.). If you can ever find a place to get a Bugatti to top speed you’ll run out of gas. So in reality, what’s the point? My friend has been racing his Lotus Super 7 for decades, not because of hp. (200) or top speed.
1. I’m sure that 750Nm is perfect balance in terms of handling/dynamics according to BMW eniginerring nowadays 2. Maybe extra 50Nm could be in CS version
Says beauty is in The eyes of the beholder. But then enforces that his opinion on the looks of Mercedes is more correct than OP. Lmfao.
If the M5CP did this good against it I can only imagine what the M8GC is gonna be like
Slower.
It will be heavier.
And more powerful. Probably only a little heavier.
What? Are you fucking retarded, just shut the fuck up. The M8CP will have 640hp and will be lighter. Get off this fucking app if you don’t know shit about bmw
Calm down Fergus
The M8 Gran Coupé is probably going to be heavier than the M5.
The Base 8 series is already heavier than a base 5 series, even though it’s shorter.
Fergus is right, Anon is confused because he can’t tell the difference between a 6 Series & an 8.
Oh my god. Calm down
Gosh dang are you always this unhinged lmao. And m8 will be lighter than the m5? Lmfao
I knew the M5 CP will be faster around track.
I wish we could see the scans
I just found the scans. Mercedes dropped the ball with this GT63S. 50k more expensive but slower for 0-200 kmh and slower around track.
This is impressive as it should be the M8 GC going up against the AMG 63s GT.
BIMMER POWER. PERIOD. #BEASTMODE
750 Nm beats 900 Nm.
And this is really surprising. Even if Merc is heavier.
M5 competition’s biggest competitor in terms of sales numbers and 0-100 km/h 0-200 km/h is Tesla S 100PD.

Since M5 isn’t about sales volume or 0-60, what’s the Tesla’s Nurburgring lap time? Since M5 is an autobahn cruiser, what would be their cross-country times be NYC-LA, with charging? LA to Vegas for the wknd? Cannonball Run times? Not really competition…
Not surprising, has an AMG Mercedes EVER beaten an M-series in a real road challenge ?
FYI: standard M5 tested by the same magazine posted a 1:34.36 (published May 2018 – link below)

And, M5 Competition posted a 1:33.93 (published November 2018 – link below)

I was interested in purchasing an M5 before than made it look generic and like any other BMW- and I cancelled my pre-order. The Mercedes might have lost in performance, but at least this years model looks slightly more compelling visually.
Then the upcoming M8 GC will suit you better.
I am getting one :)
M5 all the way.The merc is ugly and overrated.
How comes these comparisons never mention the interior? Inferior is half the equation.
