The latest issue of Autocar tested the acceleration of the W213 E63 S against the RS7 Performance. The acceleration results:

E63 S:
0-30 mph: 1.50s
0-60 mph: 3.31s
0-100 mph: 7.39s
30-70 mph: 2.62s
1/4 mile: 11.45s @ 126.6 mph

RS7 Performance:
0-30 mph: 1.51s
0-60 mph: 3.36s
0-100 mph: 7.52s
30-70 mph: 2.70s
1/4 mile: 11.51s @ 125.1 mph

They also tested the E63 S separately against the Lexus GS-F for sound (E63 S was louder and with essentially better quality), against the M6 GC for handling (they preferred the M6 GC). Since they didn't test the entire group against each other, they didn't declare a winner, although they didn't think the E63 S would have won overall...

Wow that's almost as fast as a tuned w212 e63s.

A tuned w213 will probably see well over 130mph traps

that stock 126.6 trap is pretty promising/ strong

was it article or video test?



all i have seen so far is this one and i noticed they mentioned pause/ hesitation launching , although it was referring to racestart

https://www.autocar.co.uk/car-review...ic-2017-review

"Launch the car using the Race Start function and the driveline seems to hesitate for the briefest of instants as you lift your left foot off the brake pedal – as if deciding afresh every time exactly how many engine revs to use; how much torque to allow into the driveline in the opening split-seconds of your run; how much to send to each axle; and finally, how to split what’s under the loaded rear axle between the individual rear tyres. Seems fair enough; there are a few sums to do there, after all."

126mph stock trap is insane. I wonder if they just got lucky here

Also, I don't believe that Autocar subscribes to using the 1 foot roll-out like the US magazines do with acceleration data. If you take .2s off the Audi RS7 Performance times it is dead-on with the Car & Driver test data.

So the E63 S may very well test 11.2-ish in the US magazines and maybe close to a 10.9 at the track in ideal conditions.

I don't get how a stock w213 is faster than a tuned w212.

that new engine is something else

The transmission and gearing may also play a part.

Glad I have one on order.

I went back through some recent Autocar tests to give an idea of just how good the E63 S performed in the 1/4 mile using their testing methods:

Porsche 991.1 Turbo S: 11.4 @ 126.3 mph
'16 Nissan GT-R: 11.7 @ 122.1 mph (US MY '17)

something doesn't add up as a tuned m157 is doing 100-200km in 6.5s vs the w213 doing it stock in 7.8-8.0s.

Not sure how its possible that it matching the same trap speeds.

TMC M5

Where are you seeing 7.8-8.0s 100-200 km/h? Also, the 126.6 mph trap speed is a GPS based trap speed. It would probably fall down to a low 125 mph trap speed at a track using the timing light average speed over the last 66'.

Amg63-

its 0-200 km is just over 11s which normally translates to about 8s 100-200 time

If you go by this video, it is about 7.6s 100-200 km/h. But there are so many variables at play here. The 6.5s 100-200 km/h times you are quoting for a tuned E63 S. What were the ambient conditions (temperatures, altitude, humidity) and slope of the road on those particular runs? Also, technique plays a huge factor. Did they start the run from a complete stop or were they picking the optimal gear to start the run? Doing dozens of 60-130 mph runs in my cars, picking the optimal gear from a roll was good for .3-.5s over a standing start.

Amg63-

Just lookup the 100-200 thread in the w212 section.

On average the tuned w212s are doing AROUND 6.5s as many have tested this. We are talking about from 0 just like all the acceleration videos of the w213.

If you look at all the videos of it going from 0-200 its doing 100-200 in a range of 7.8 (7.6s for one) to 8.0s and the 0-200 is around 11 or a bit higher.

Tuned w212 e63 are doing significantly faster times for 100-200 and 0-200. I was just saying I would of thought the difference should be greater based on the w212s 1-2mph higher traps as w213 almost traps equal.

I think right now your sample is too small of a population to draw any definitive conclusion. As more data/tests come out and actual drag strip runs, you may see results more inline with your thinking.

But even if you look at the Autocar test data it ran from 60 mph to 126.6 mph in 8.14s (11.45 - 3.31). But that range is 4.5 mph more than a 100-200 km/h run. Check your own vbox run where you ran 6.7s 100-200 km/h. See how long it took you to go from 60 - 126.6 mph. I would be curious to see what your results were.

i wouldnt say tune e63 w212 is doing 6.5 100-200 "on average".... from that thread, fastest tuned w212 was 6.6 i think.... so throw the outlier out and you have ~6.8 for tune only w212

keep in mind a tuned w212 prob has about 80-100whp more than stock w213, so the fact that w213 is running pretty much same times/trap as tuned w212's is pretty impressive

Amg63-

that is exactly what I'm trying to say. That I'm surprised it can be running those traps despite the significant difference in power+ 100-200 times between them.

gaspam

I don't think a 6.8 versus 7.6 , on different cars/different days, is a huge difference as that 8/10th of a second over 100 kph spread could be just a difference of hot vs cold day test conditions/ full tank vs empty tank , etc....

The trap speed on the 1/4 time however speaks for itself

Amg63-

yup, well I'd say more like a full second difference as it's easily 6.6 vs 7.6 and in some cases 6.8 vs 7.8

the traps definitely show the stronger top end of this new motor. I suspect tuned w213 will easily hit over 130mph.

That trap speed is FAST!
In this video you can see how the rpm can be adjusted when launching this car!
