Caterham Weight

[sdio]

Hi all,

I never understood what is the real weight of a superlight and if this is with full fuel tank or totally dry from liquids

I remember having read 468kg !?

That is low if with full fluids.

Mine none superlight but superlight full spec with all useless parts like heater and the lot off but windscreen on was told to be 510kg with 20lt fuel in it which is a lot in comparison to the 468.

The claimed weights I have seen have all seemed at best 'optimistic'. Even when taken as a dry weight; which is what I think they claim it is.

My 2012 R300D SV with aeroscreen and Apollo 13" wheels comes in at 585kg with a 1/2 tank of fuel.

My R300 Superlight (2002 S3) weighed 540kg on PGM's scales with all fluids and 1/2 tank fuel.

According to the printout, my Superlight, which was dry sumped and upgraded to R300K spec, was 495kg on Solutions Racing's scales. It was aero-screened, had a lightweight race battery, no heater and at the time had 1/4 tank of fuel.

In that case i should forget the sub 500kg and the 510 of mine with lightweight battery tullets no heater no carpets or mats wide track appllo tank 6 speed lsd watts and 13' should be about right with 20lt of fuel i assume.

R400D with all the trimmings - screen , weather stuff , spare and the random stuff I keep in car etc was 590kg . Not saying what it is with me in it ....

So the 270/310/420 and 620 monicas are a bit fanciful. It's not only the weights that are a bit optimistic/misleading, but the top speeds too. The cars are quicker with an aeroscreen than a full windscreen and, 620 excepted (620S 10mph slower than R) only a single top speed is quoted. So I doubt that most cars will actually achieve the top speeds quoted because most have screens. That's compounded by choice of wheels/tyres and gearbox.

I have to say the 0-60 times seem a bit random too - is the 360 really only 2 tenths (4.8 vs 5.0) quicker to 60 than the 270 - and does the LSD of the 420 really allow it to be a whole second faster than the 360?

2006 Freestyle S3 spec'd with lightest components and Cossie 2.3 l weighed in at 1186 lbs (538 kg) with tank approximately 7/8 full - topped off tank about 20 miles away prior to dyno session where car was weighed. Lots of little things can add up (or subtract down) to significant amounts.

Caterham used to specify the added weight of all of the extras - heater, screen, even paint - which, for an ultra-lightweight car seemed a sensible approach. It's a pity we don't now know how much the 6 speed box is heavier/lighter, which are the lightest wheel/tyre combinations etc etc. It might just give pause for thought if we are buying a car because it is ultra light - and find that the "luxury items" we are speccing make the car 10% + heavier.

Fluids are probably 25-35kg depending on model if you assume half a tank of fuel.
