Cool. Is that a 300 or 400? AWD or RWD? Thanks.

C250 + Brabus power kit.
C250 is EU rwd version of C300

i will not confirm or deny anything but "my friend" has gone 220km/h
was super smooth, felt effortless. turbo platform is fun!

So, just how stable is the car at speeds over 100 mph?

I've had mine up to about 90 mph for short bursts, and it was rock solid, but I haven't had it beyond that ... yet.

Only gotten mine up to about 100mph so far. Haven't been alone in the car without my daughter in an open enough space to really try and test it yet.

Off Topic, but does that mean the Brabus Kit for C250 will work with C300 in the US ? I was told by Brabus that they will release another model for the C300 and I have been waiting for it for sometime now. No news at all.

How many mph did the Brabus kit adds to the 160 mark? Didn't think the turbo 4 banger could go that high.

I am doing daily 110mph+. Car is absolutely stable and good on these speeds.
This weekend i did 900km trip with average speed (including two stops) 162kmh (around 100mph).. I was able to do 200 miles at 210-230kmh (135-145mph).

samyc300

212km/h or 135mph SF to LA freeway I-5. It's restricted, so could not go faster. Very stable and smooth at high speeds.

car cut me off at 140mph. super smooth, had plenty of room left for more, did it on route 2 in MA

TensaZ

160km/h in sport+, handling is crisp and car is very stable. I can't imagine hitting a pothole with that speed though...

In comfort mode it takes about 3 months to get to 140+km/h. Also tons of understeer.

E3E3

178km/hr - smooth as silk & felt like 100km/hr.

Love it!

212 in a turn (45.078425, 8.973871). I don' drive fast in the straights. The car wasn't really so firm and the steer was a bit light and unresponsive but nothing serious although you live inside the Nurburgring circuit ;-)

I thought the W205 was electronically limited to 130mph. Is that true? Are there country specific limitations? I haven't tried testing the limits. Yet!

JayGoGilla

140km on the dvp(highway) at 2am. Other than that no where in Toronto I would feel safe going any higher, plus police out in force.

chicagofan00

Most cars in the U.S. Seem to be limited to somewhere between 130 & 155mph. I was able to get my E92 up to 155. Never maxed my S4 out but did about 110 in it...I think that was limited to 150 as well but could be wrong.

AZ64BenZ

Did 168km with my c400, very capable and acceleration was effortless, overall I felt very safe driving at high speed. No strange windnoise.

I did end up with a collection of bug corpses on my front bumper that day.

StanNH

131 mph and 136 mph for the C300 and C400 according to the real world, published test data.

l3it3r

I've had the C400 over 130mph multiple times, felt just fine.

pavloPL

237km/h on german motorway as well, I was pretty heavy that time so could not reach more.
