I know outside the AMG trim, there is not launch control, but I was just wondering if it is normal for my rpm's to be limited so low. I know when I got a C300 as a loaner, brake and gas pedal I was able to burn out, or at the right amount of gas, have a good launch without needing launch control.
You're in luck! I actually made a post about this a few months ago: Start-off Assist? where I went into thorough detail about what the car does and how it behaves under certain conditions. It is specifically called out in 2017+ CLA250 owners manuals. Copy-pasted and edited for convenience:
"So I did a bunch of experimentation here and I have the results!
First of all, it really works on 2015 models at least, even though it's not mentioned in the owner's manual. There is absolutely no indication given on the dash that you're doing a "start-off assist."
I timed 0-60 at 6.1s at best using this method. MB quoted 6.9s for MY2015, for reference. I used the method I described: ESP Off, Eco Start/Stop Off, Sport Mode, floor brake, floor accelerator, let go of brake once revs settled. Only got a tad of front wheelslip once and not on any of the other runs, 4MATIC definitely helps here.
The car short-shifts into 2nd when you do these, whether by design or because it sees the revs rapidly climbing, not sure, but it definitely keeps the car in torque band nicely.
If either engine is cold, drive mode is Eco, or ESP is on, it won't raise the revs past ~1000rpm.
Once, when the engine was really cold first thing in the morning, the revs climbed rapidly, the car tried to clutch, and when it wouldn't move, it disengaged the clutch and rev'd up again. I never tried this particular scenario again for fear of driveline wear."
Here's a video I took of it in action. This is with my 4Matic model. Give it a shot! You don't see it in this run but I have chirped the front tires in some other runs while doing this.
Though, I wonder whether there is some mechanical difference in 2017+ CLA250s that makes the car more durable to launching like this, and that's why 2016 and earlier CLAs don't have it in the manual...oops
It's a 250 not a super car. I personally wouldn't launch or abuse the transmission, engine or tune it. Long term reliability is already an issue so you dont want to compound it. Plenty of horror stories with tunes throwing engine codes and causing limp mode.
Hi folks. Very new owner here! Having a read about enabling Carplay on my CLA250, but more importantly...
I live in a block of apartments and we have a stacker system in the garage. When we move the stacker up and down, it sets the alarm off because of the movement/tilt.

Hey guys, I have searched for similar case but haven't found. I own CLA200, 2013. I obviously don't have CarPlay or command online. I am wondering if it's possible to replace the radio (or what does it take) to a newer version of NTG and will it allow me to use CarPlay?
I have this type of...
Just ordered a 2020 CLA 250. (Feb 2020) Missed the stop production cut-off date of Dec 2019 on the Jupiter Red, had to take Patagonia Red. Any thoughts on the difference between the two and are there any pics showing the two colors side by side?
Installed new rotors and brake pads on all four corners. Vacuum drained and replaced brake fluid, all factory parts. What a difference, braking was much improved. Several months later, the brakes seem to surge while braking downhill. Thought it might be air bubbles. My mechanic repeated the...
I had some time after lunch today so I dropped by the local MB dealer to check out the 2020 CLA models. They only had two of them available both in the hideous taxi cab yellow. Here are just some random thoughts and first impressions.
