Your use of KMh instead of MPH, and that a C180 is not a US model makes me think your speaking of a Euro edition car. Even if it is very similar to the C190 here, the exhaust system is something that is normally a big change for US standards. I can't provide an absolute answer to your problem (although some type of exhaust leak is indicated), but want to make sure you realize that if your getting fumes in (especially at speed), this is a major danger and you should not operate the car. Toxic fumes are probably present and can exfixiate you or at least make you sick or knock you out...all bad things while your driving. This really should be remidied immeadiately.
It depends on what road you are driving on.
40 km @ 100kmh 40/100 = 2/5 of an hour 2/5*60 = 24 minutes
141.4 km/h northwest
299
Can they fly?! These things are real jets! They have 100kmh (62mph) avarage speed
900 kmp
if a car goes 220kmh in 4.5minute it can cover 100kmh
Sounds like something is slipping...tranny service(automatic) recommended.. dave
Could be your tires need to be balanced or you need new tires.
Open up Forza 3, and try for yourself - or visit the Top Gear website, its on BBC.
1 km = 0.6214 miles so 100kmh = 62.14 km per hour.
The peoples car. Hitler, prior to WWII, wanted a car that was affordable to the masses. that could be fixed by the owner and could go 100kmh on the autobahns
