MG MGF Technical - T.F. 135 ,0-60 TIME

M.G. Claim 0-60 time of 8.2 secs,Autocar road test gives 7.2,big difference, which is right? Regards.
RoyB

Hi Roy, my bet would be the 8.2 as a VVC is stated as 7sec and a 160 trophy as 6.9.

Dammit,COLIN,That wasn't my prefered answer.I suppose logically if it's 7.2, it's getting mighty close to a TF160{6.9},so is it worth the extra brass?On the other hand, an improvement of 0.4 of a second{8.2/8.6} over my old 1.8i doesn't seem much from an additional 16bhp{118/134}.Anybody got any definate figures.Regards.

Think you can be pretty certain that the MGR figures will be the most optimisitic and will have been obtained in the most perfect conditions and with the most brutal treatment of the engine and gearbox.

The most important number for acceleration is Torque and this has not changed that much between the F1.8i and the TF135.

Getting numbers wrong in a magazine article also seems far more probable than an MGR brochure that the lawyers will have checked.

In short believe MGR, ingore anyone saying they are understated.

No-one will ever match the manufacturer's 0-60 time in their own car. Human nature means that an owner could never sit in first gear at the rev limit and just let go of the clutch - not in a car that has just cost £16k or so.

Problems with 0-60 are:

1. Depends largely on how much you're prepared to mash your gearbox - they *do* get destroyed when manufacturers do their 0-60's.

2. Depends on how often you have to change gear from 0-60! Only once in a VVC F as opposed to twice in an MPi, but I think that might be standardised for published figures.

3. Some cars are just impossible to wheelspin in the dry due to weight, weight distribution, torque and tyre characteristics (e.g. VVC F) which I'm sure makes it much easier to do an unskilled fast 0-60 in the real world.

4. 0-60 really is a rather crude indicator of usefulness/enjoyment in the real world, unless you really do get your kicks from racing Scoobies and Elises away from the lights - in which case you're doomed to failure anyway.

5. Engine performance is dependent on air temperature and humidity.

Maybe the most useful number would be to calculate the mean torque available between 1000 and 6000 rpm and divide this by the mass of the car? Dunno. For example, I'd have thought that the torque of an Elise is similar to an F, but it's the reduced mass that makes it accelerate better.


David Bainbridge

am i right in saying that when the manufacturers calculate these times and figures that that do so without little ‘accessories’ such as wing mirrors or anything more than 1/2 litre of fuel etc. ?

IMHO, that mass is THE most important thing on a good 0-60 time. Take it with a passenger and you might get an extra 0,5-7 sec.

See the Elises and the caterhams...
