Kerbweight difference between ff and Cup.

[flyer447]

Just been reading the posts on the weight difference between the ff and the Cup. I had hoped it might be close to the 20kg quoted on the Clio, but I see you guys reckon it may be closer to 10.
This is disappointing, since I bought the Cup because of weight saving and (marginal) performance advantage rather than cost.
I weighed the spare wheel and toolkit today, and it weighs a stonking 16kgs. I know that this will make an un-noticeable difference, but I just feel that a car should be as light as possible, so I think I will risk carrying an inflator can in the glove-box instead.
Am I right in thinking that the 500 Abarth does without a spare?
I can't imagine that this will have any detrimental effect on weight distribution and handling, but the spare wheel must contribute something to rear impact protection. Are there any insurance implications?
Has anyone tried any weight saving ideas?

ive got a normal 133 with the cup chassis option - first day i got it i took the back seats out - thats got to be a 20kg ish saving. Also dont fill it up to the top with fuel - 20l of fuel is about 15kg so there is a saving to be had there.......hair cut maybe?

u think that the spare wheel is a safety device :?: :?:

That's the tone at gutter level then :lol:

Maybe a slow puncture that you spot whilst parked could be fixed with a can, but if you go any distance and you get a flat that goes down quickly, the sidewalls don't last long, then an inflation kit won't be any use. I did less than two miles from pothole to finding somewhere to replace the wheel and there were holes in the sidewall already due to the heat.

You're right in saying the 500 abarth has no spare wheel but it's designed that way so the weight distribution is how they intended it.

Having said that, a spare wheel doesn't weigh a great deal in terms of that so it won't have a negative effect other than quite possibly being stranded with a puncture.

There won't be any insurance implications etc as there are many reasons not to carry a spare. there's no structural rigidity to worry about either.

Best to kick these thing off early...


Letstorquebhp.com have a performance clac (seems to be down at the mo), a bit basic but it will give you what they think to 0-60 is (something like 8.1), then just knock off the 16kg


I dont think it takes anything really into account (gearing etc) other than the weight and bhp @ the flywheel.

To be honest the Cup version of the 133 is designed to be a bargain rather than the weight saving. On the Clio 172/182 you made a genuine weight saving on the Cup versions as they ditched things that actually weighed something.

The 133 Cup is cheaper but comes with the Cup chassis but for that reason, you miss out on the following -

Tinted glass
Manual Aircon
Independent sliding rear seats
Rear headrests

The only real weight saving you're going to have is the airconditioning unit, although I thought the Cup could come with aircon?!? (I took the above from here : https://www.renaultsport.co.uk/roadcars/twingo/specifications/Default.aspx)

The Cup is a money save to be honest, you get all the driving fun, none of the frills all for a bargain price.

Let's face it though, the difference in weight/performance on the road would be unnoticeable. In the same sense that a non-Cup 133 will keep up without a problem with a Cup chassis'd 133 on the road. A few KGs less again wouldn't make a massive difference. I'd even go so far as to say the same from experiencing a full fat Clio 172 and a Clio 182 Cup. On the road, the difference was so minimal you'd have a job spotting it.

If you could knock off say, 50-100kg from the weight of a Twingo that'd probably yield some performance benefits but saving say 20kg is difference between me driving my 133 compared to someone that bit lighter, on the road you really wouldn't see a difference.

On a track though, I'd expect every saving to be important.
