M Series Kerb Weight

[StewB_v6]

Hi all, has anyone actually weighed their M series? I'm particularly interested in the later 3.0 V6 enginec cars (I have a '78 3000M with OD). Anyone with any info they are prepared to share?

Thanks, Stewart.

In the books thy are listed as 20cwt, so an imperial ton.

Never actually put mine on a scale so dont know what it is, should be lighter with Aluminium items and Homer Simpson speed holes!

[StewB_v6]

Yep, seems to be quite a range depending on who you want to believe. Have seen just under 900kg upto 1050kg quoted but I guess some could actually be Kent engine numbers & I've no clue where the Triumph 6 cylinder & accompanying gearbox ranks vs the Essex. I'd guess the Essex is worst case & the all iron gearbox + bellhousing only making matters worse!

My 2500M Owners Handbook gives the following information:

Kerb - basic: 1116Kg, 2240lb
Max gross vehicle weight: 1202Kg, 2650lb

I would expect the 3000M would be similar if not slightly higher. I suspect that your 900 - 1050Kg figures are on the low side for an unmodified vehicle.

Would be surprised if the Essex is much heavier. 1050-1100 kg for a standard car sounds about right. 900 is a stripped out road / race car. It’s expensive to get sub 900 but doable.

Excellent info, thanks for the replies.

Distribution F 52.5, R 47.5
Laden as tested 22.75 cwt (2,544 lbs, 1155 kg)

3000M Motor w/e Dec 7 1974
Unladen weight 19.6 cwt, 995.7 kg (with fuel for approx 50 miles)

Brilliant, really useful info. Thanks for digging that info out.

nice find, so the 'light' 1600M is tested just as 'light' as the 2500M, could not have guessed that
a 3000M = almost 100kg heavier tested as the 1600M and or 2500M.

Just noticed the typo in my TVR Handbook - Kerb weight should be 1016Kg - close enough for TVR!!!

Well found Mr Tiger!

After reading GTRene's comment I have had a look through the info and have a few comments to add:

• As I understand it the old definition of Kerb Weight should have been a full tank of fuel*

-Looks like driver only for test?

3000M Motor w/e Dec 7 1974
Unladen weight 19.6 cwt, 995.7 kg (with fuel for approx 50 miles)
Weight as tested 23.3 cwt, 1183.6 kg

-Tested with full tank of fuel + driver only?

2500M Road & Track Aug 1977
Curb weight lb 2275
Test weight 2370
Distribution F 53, R 47

• With this spelling is this US Spec. with smaller (12 gallon) tank?*

-Tested with full tank + driver only?

1600M Autocar w/e 3 Apr 1976
Kerb 17.6 cwt, 1974 lbs, 896 kg
Distribution F 51.4, R 48.6
As tested 21.4 cwt, 2,398 lbs, 1,088 kg

-With almost 200Kg increase for test over Kerb Weight (full tank of fuel already), was this tested with passenger + luggage (touring test)?. I see what you mean GT, this does seem strange!!

Hope its of interest

Chris

In summary there may be some comparing 'apples & pears' going on!
I would expect 2500M & 3000M to be similar (3000M maybe slightly heavier due to fuel load, gearbox and diff) and 1600M considerably lighter under the same conditions.

Agreed.

[GTRene]

I also came across some weight info in my TVR car books, but read them long time ago... but there were also many old test articles combined in 1 or 2 books, I remember something like, a 3000 taimar was almost 100kg more heavy then a 3000M I found that a bit much, others claimed a bit les of a difference.

I forgot the title of that TVR book, but it was full with TVR test of those early years, I have maybe 8 or so books

3000M is about 100lbs lighter. That Triumph motor is heavy.

[Monsun]

Just seen this thread. Had to weigh my 3000M two years ago to do some sprinting. This was for handicap purposes.

It came out at exactly 1000kg with quarter fuel and the spare wheel removed. It carries a bit of additional weight as it has a roll bar fitted with a diagonal bar.

Last time my race ready production race car was weighed it was 930 kgs with a very heavy repaired bonnet
