z4m , whats the actual weight??

Post by Beedub » Fri Dec 15, 2017 3:20 pm

Has anyone weighted their car recently???

im seeing so many different figures for the weight???

roadster 1410kg and coupe 1425kg is what i though it was??? but then i see some publications listing roadster at 1485 and the coupe over 1500???? surely that cant be right??

So just wondering if anyones actually weighted their car or seen the corner weight figures?

Carfolio have the roadster at 1485 and the coupe at 1495 kerb, I think that's standard weight plus 100kg AFAIK.

Owner's manual says:
  • 1,453kg for the Roadster
  • 1,465kg for the Coupe
...but doesn't specify whether that's 'wet' or 'dry'.

I had mine weighed a while back with half a tank, no driver. Came out at 1385 iirc which surprised me tbh. I've managed to lose a bit more since then so I'd be interested to see what it is now.

Yes, I was expecting to be not a lot below 1450 at the time. BMW can we a bit odd with their quoted figures. For instance the e46m3 quoted weight by BMW includes 3/4 tank of fuel and driver, whilst when they quoted the weight for the CSL that was with no driver and half a tank or something, naughty imo.

This website http://www.rri.se has the curb weight of a 2006 Z4M Roadster down as 1467kg (full tank of fuel and all fluids but no driver), so about 1425kg-ish without the fuel. The S54B32 engine also made 94% of its quoted power and torque figures on their dyno which seems pretty good. Interesting website!

Sorry for the delay, it took a while , my fancy new jack is too high to go under the car :oops: and I was hungry when I got home. Anyway.....the results are, it needs to go on a post Christmas diet. :oops:

Weighed with full trim, inflation kit, a few cds and just over 3/4 of fuel.

My APs and rear ARB are lighter than standard but the exhaust valve adds quite a few kgs back.

The good news is the balance is excellent.

Without driver

51.1% front 48.9% rear
Corner weights are 50.1%
Total weight is 1483kg


With me in the drivers seat

50.23% front 49.77% rear
Corner weights are 50.5%
I weight 88kg, therefore also need to diet a bit :?
Total weight with me is 1571kg

I need to get mine on those scales, I almost don't believe what I was told before, though it was on tried and tested corner weight scales.
Something for the new year :)

You're welcome to use them mate, that's an open offer to anyone if they wish. :)

You've saved weight with your Supersprint, alloys, Carbon airbox, interior trim and especially the drivers seat so a figure beginning 13XX sounds possible. 8)
