Message: <blockquote data-quote="bmwcar" data-source="post: 237417" data-attributes="member: 2286">the top speed of a 99/00 318i auto is 202kmh based on the owners handbook....this would be without aircond, 2 persons, 1/2 tank of fuel and standard 16 rims.... with 17/18 rims and a/c on, it should be about 185to190kmh which means taking into account a 5% speedo overstatement (which all cars suffer some degree from)...should be an indicated 190 to 199 kmh....... there is no issues with the engine with running the car at 180kmh or so for extended periods of time as long as the revs are below the redline and the throttle not floored all the time........ however, think running at the redline for a long time will stress out the waterpump, alternator and power steering pump as these are belt driven from the engine and would be running extra fast...think over a few years that might wear out faster.... that said, my current car 323ci -  has been driven enthusactically over the last 5 years and 85k km and there has; to date; been no issues with the water pump, alternator and powersteering pump.....and these 3 items are the same for 4 potters and 6 potters just changed the waterpump last month but it was more preventative as i had to change a leaking hose at that time.....</blockquote>
