 545i slower then 540i!



What's this all about??

Now look here...

Someone want to explain the 0-60 time difference? The 540i is 5.5 and the 545i is 5.7! The torque numbers are nearly the same, the 545i weighs about the same, and has more horsepower. Why is it slower? (I mean it's not much difference, but one would think the 545i would be a good half second faster than the 540i)

When it gets down to that, I say big deal. People can't tell the difference. It could have been the test driver, air temp, tire pressure, whatever.

I remember in the 80s, anything quicker than 7 sec in the 0-60 was fast. Now a lot of cars are floating around 7.

I measure I would like to see recorded more of would be 30 - 60, or 50 - 100. With many of these cars, thats where you figure out where the real power is.

That's true, my 325xi has a disappointing 0-60 time (7.8 seconds) but it still manages to have good passing speed on the freeway. It would be interesting to see what it gets in the 30-60 and the 50-100 range.

I guess it depends on where you look for the data. The numbers are all over the place for both cars. Here is a review of the 2004 545i (auto I think) against an STS in MotorTrend and their test data shows a different set of #'s (note the 545i 0-60 time of 5.4). So, not sure how much stock you place in some of the sites facts over another.

That's an awfully optimistic number for the 540 and a relatively pessimistic number for the 545.

0-60 my C5 is about a 1/2 car length ahead of my 545 (both auto)
50-100 the 545 is almost 2 full car lengths ahead of the C5.
