Maximum speed: Km/h

Max weight of front axle kg

Max weight of rear axle kg

Wheel rim size

If people could post this data for 1850 and Sprint that'd be brilliant, they've promised a prompt answer.
From the 1850 BL workshop manual alone you cannot find all the answers,
however top speed is approximately 160km/h,
max. gross vehicle weight is 1329kg,
and wheel rim size is 13x4.5J.

Dolomites don't have a 50:50 front:back weight distribution, it is front heavy.....I would guess 729kg front : 600kg back?


A Sprint has a max. gross weight of 1375kg, has 13x5.5J wheels and a top speed of about 180km/h.



hope this helps a bit,

From the SPRINT bible comes...
Kerb weight (including options)..........3031 lb (1046 kg)
Maximum axle load; front......... 1466 lb (665 kg), rear.......... 725 lb (1598 kg)

Yes, this is the way its printed in the book. Its fairly obvious that its a typo....and I know it doesn't indicate true weight distribution, but I hope it helps.
Happy Easter.

That maximum axle load is correct with the rear being heavier, sure an empty car is nose heavy , but 4/5 up a full tank of gas and a boot full of luggage (and possibly a loaded roof rack) changes that and THAT is max load, the figure asked for!

Thanks Rob, they obviously got their rear lbs to Kg conversion a bit wrong :D
Perfect, the total weight of my 1850 according to the last MOT is 1080 Kg, so Sprint and 1850 can't be too different in the grand scheme of things.
I'll send the figures off.

26 psi all round for standard on 175/70 4.5j 13"
29 psi all round fully loaded.

That's a recommendation from a tyre manufacturer for the tyres fitted to my car, I wouldn't take it as gospel for every car and every tyre, but it's good for me. :D
