My GOlf GTi (mk 4) has a stated 0-60 time of 8.2 seconds. I had it chipped to 190BHP from 150 and that should have taken about a second off this time (it certainly feels it). I know 0-60 times are usually a little optomistic as allegedly manufacturers crunch gears etc. I'm now looking at new cars (still) such as the Audi A4 convertible, where the base engines (1.8T and 2.4 V6) look considerably slower than my golf (9.4 second 0-60) - can they really be that much slower - I know the car weighs more but surely a V6 engine is going to be fast - I don't want to get something slower.? Also, the BMW Z4 2.5 0-60 time is stated as 7.4 - again in line with my golf - can a sports car that is aerodynamically designed with a 2.5 litre 6 cylinder engine really only be as fast as the golf? Seems odd to me. Although the Z4 will prob go round corners faser.

I don't know about the other things, but aerodynamics will have nothing to do with 0-60 times.

I wouldn't worry about 0-60 times too much, they're a load of old cobblers.
Fo example,
car a could do 0-60 in 10 secs
car b could do 0-60 in 8.7 seconds
but
car a could do 0-59 in 8.5 seconds but lost out 0-60 by needing another gearchange for that extra 1mph.
There are lots of other ifs and buts too.
You really should just test drive them.

Aerodynamic drag will have a small effect on 0-60 times.

Loads of things effect 0 - 60 times, weight as you have mentioned, torque and very importantly gearing. These new cars may require another change before they hit 60 therefore increasing the time but I suspect weight plays the biggest part here.
However, be realistic. 0 - 60 times are SO irrelevent it's untrue. Unless you actually race on the roads from 0 - 60 and then stop, it isn't really a practical measurement. Drive the cars, see what you think, that's what's really important.
If you really do need to look at statistics to prove how fast a car is, use standing 1/4 miles and in-gear acceleration to give you a better idea.
Good luck.

I think its best to look at acceleration figures in magazine road tests and not rely on manufacturers figures. I have heard it said that Audi are sometimes conservative with their times.
Best to look in the back pages of Autocar, Evo, Car, Top Gear, etc. to get independant road test figures.
Where did you get the BMW Z4 time? Autocar road test results page says 0-60 in 6.6s for the 2.5.
Bear in mind your Golf is a bit lighter than a Z4 and quite a lot lighter than an A4 Cabriolet. So will have a pretty good power to weight ratio in comparison.
And what about mid-range acceleration? 30-50 and 50-70 times are an indication of overtaking ability which some consider to be more relevant than standing start times.
;o)

There are progammes available that can calculate 0-60 times, but is that what you really want? if so, get an Evo or clone. Or is it the driving experience? Get a V8 convertible.
V6 engines and turbo engines are frequently gutless at lower revs, so thrashing and clutch slipping are required for maximum accel. Including placing at engine revs at max power and moderating wheelspin with the clutch, good fun on a single cylinder dirtbike, a bit expensive with a car though.
|
In gear times are much more important, though if you want fast 0-60 and VFM get a motorbike, my ZRX will do 60 in 3.4 secs, an R1 or similar just under 3.0 secs in the hands of a skilled rider who can get it off the line, and 100 in 5.
|
Many manufacturers don't even quote 0-60mph times, they quote 0-100kph times and translate the brochure to read 0-62mph - the difference is significant.

Who cares how fast your car go 0-60 or 0-62 apart from your ego ! The faster you accelerate the more pollution you create in terms of noise and filth belching out of the car, get something more environmental friendly.

The smell of burning rubber and castor oil... the stench of fear.... nothing like it.

Not exactly. Some cars can go faster and use less fuel. If two cars have identical emissions, but one is faster, then it is likely that when driven at the same speed the faster one will use less fuel.
Having said that, an environmentally friendly car is a good suggestion.

By gum, my first car did 0-60 in 22 seconds and I thought that was pretty nippy.
|
It's something you will rarely do - IE 0-60 in the quickest possible time - I take them with a pinch of salt - I had an old 306 S16 with 0-60 of (As per mags etc) 8.4. I also had a Rover 200 Vi - 7.5 0-60 stated but there was no way the Rover would out drag the 306.
