I made a 0 to 60mph test in my C200 W206 and it made kia times, I did the test several times and hit 10 seconds I live at 2800mts above sea level. Anyone has tired this test at the same altitude?

Doesn't sound right, should be around 7.5.

While the official 0-60 for the C200 seems to be 7.5 seconds from what I can find, at 2800 meters / ~9000 feet, that's not gonna happen. At that altitude, the engine makes only about ~70% of the possible power at low rpms until the turbo spooled up sufficiently, so the problem is these tiny 4-cylinder engines at that altitude have a gigantic turbo lag. I once took an Audi S3 to Mammoth Lakes which is at ~8000 feet / ~2400 meter. The engine was a complete dog at that altitude. It barely got off the ground until finally the turbo boost kicked in and then it slammed everybody in their seat, because the power surge was so severe going from low atmospheric pressure to turbo boost pressure. The car was horrible to drive at those altitudes. I'm normally at sea level, so the contrast was quite jarring.

Does the 48V mild hybrid system help in that case? Don't know if the C 200 had one.

Not familiar with the C200, but it should help as it's meant to torque fill, however, no idea how good it will perform at that altitude. Admittedly, the S3 didn't have MHEV, but I'm guessing MHEV struggles to fill torque long enough until the turbo kicks in, and the engine torque/power will still be down ~30%, so even with MHEV, you are 30% short in combined power/torque until the turbo can compensate for the lower atmospheric pressure, but even the turbo probably can't fully compensate.

Understood.

Mid hibryd tech doesn't help that much. You can feel that at low RPMs the turbo lag is enormous, one it kicks in has a nice boost. I think there must be a ECM configuration for high altitude conditions? thats one of the reasons why fuel consumption of fuel is very high 12-13 lt/100km city range with heavy traffic. Whe I'm running in highway I can get 5 to 6 lt/100km
maybe a complete hibryd version or with turbo electrified (C43) should work better.

Might have to mess around with the octane at high altitudes, I don't recommend going below what MB asks for though.
