Beating a c43 amg on a straight?

Avex · 11-11-2018, 11:51 PM

Dragged a friend with a stock c43 amg the past weekend and he was constantly pulling ahead of me in first and second gear. I'm pulling up stats and while the car has more torque and power per rpm, the m235i is roughly 250kg lighter and has better power to weight ratio.
Am I just horrible at launching the car or is the c43 simply a quicker car?

So you're in an M235i?

I've run against C43s twice in my stock M240i and the first time we were even for about 100m then he turned off.

the second time, I got a clean but slowish launch, and I heard the C43 spin its wheels for half a second. it was enough to get ahead and stay ahead. Just before I shifted to second (6MT), it got almost got even, but it had to shift too? or maybe it gave up. after about 150/200m, the C43 turned off too.

Both times, I put it into Sport + and just launched it. I don't know if I've got launch control, but if I did, I don't know how to activate it.

If its any use the M240i as tested here - before the EU strangehold was applied - is a marginally quicker car than the junior AMG. Not a lot, but those points of a second mean the world

.

Of course, I could corroborate that with further evidence from the USA, where both cars have been more extensively tested, but the EU has put a stranglehold on that, too. You can read our content, but we can't read yours. Thanks, EU, "EU" certainly know what's best for consumers.

Yup in a stock M235i bar a couple lightweight aesthetic mods. Plenty of human errors and incompetencies that largely contribute to the result. I manually shifted the first time and each time my mate would pull ahead a split second after I shifted, which seems like it maybe a late start on my end. 2nd time around I just went into S mode and let the zf do all the work and it was alot closer but still felt initial torque let me down against the c43 which seemed quicker off its feet, it's the coupe variant, but the weight difference is still 200kgs+. Might I add the c43's exhaust was surprisingly loud, I've only ever heard my exhaust from the cabin with the window down and it never nearly sounds as loud, but then again was behind the c43 each time it made those sweet exhaust notes.

C43 has a sport exhaust option that really allows the sweet sound of its engine to be heard. If the AMG was a 2019, it had a noticeable bump in hp and Tq range. The 9-speed tranny was also programmed to shift faster than previous models. The 2019 is also AWD only.

Avex · 11-12-2018, 09:07 AM

pretty certain it's a 2017.

Don't forget tires - they will have an effect upon the outcome.

Avex · 11-12-2018, 04:00 PM

Might be. Have rft potenzas down the front, PSS
down the back.

The 2017 C43 is AWD and is a bit underrated in power. Mags have tested to them to run 12.6-12.8@110-111mph. It's not surprising to me that he was beating you off the line and in such a short race, especially if you've got a stock M235. He can brake stall and build boost and not have a care about wheelspin.

Next time you race him, go into DSC Off so that all nannies are off and you have full power and put the shifter into it's sportiest setting but let it shift itself. Put your foot firmly on the brake and very lightly on the gas pedal (i.e. about 1200rpms). A split second before it's time to go, hit the gas about 30-50% (rpms at around 2000rpms) while still hard on the brakes. When it time to go, release the brake and feed the car gas while managing wheelspin as much as possible (wheelspin completely kills acceleration times, but so does bogging). This is call flash stalling the torque converter. it should help with the launch while not completely roasting the tires.

Lastly, we all think we're great drag racers, but most of us aren't. Go to the drag strip and you'll see what I'm talking about. Most people can't post anywhere close to the mag times with their stock and modded cars. It is a science and most suck at drag racing. Additionally, RARELY do both cars leave the line at the same time. This is called reaction time. Assuming the same exact cars and drivers, if one were to leave the just a 1/2 second after the other, it would be about 5 car lengths behind the other at the end of the 1/4 mile. The perception to the observer in the stands is that the car that left fractionally earlier was quicker/faster. That's not the case. They both were accelerating the same. The first car just got a head start. Just some to consider.

He is right - I have done some amateur drag racing at the track - what happens in the first 60ft will typically determine the race results if the cars are fairly matched.

I don't know about that. I was pretty consistent. lol

the awd is quicker and won't have rear tire spin issues when using launch control. my rwd was skidding a bit in the hiney before im moving forward. i'll try launching the car myself at 2-3krpm

You don't count. You have an AWD auto

You simply mash the brakes, mash the gas, and release the brakes. Done.

I know, right! It's almost a completely different sport with all those goodies at your disposal - not that it wouldn't be fun to have them at the strip.

TajoMan · 11-16-2018, 04:13 PM

c43 amg is also awd with auto tranny.

At least we know our car is matched (or faster) with same configuration. lol

khoanguyen0705 · 11-19-2018, 06:53 PM

Stock M235i would beat the c43 AMG. If you're not certain about it get a tune to make sure lol.

WolfGTI · 11-19-2018, 09:27 PM

Nope.
