Caterham CT-05 Renault

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.

And here is some technical information about the chassis thicknesses and construction. Again I think this is the first time certain details have been shared about a modern F1 car. Thanks to Mr. Thomas.Image

Chassis diagram appears to show half of a monocoque that totals ~ 40 lbs. So is the complete monocoque ~ 80 lbs?

More or less that's what they usually weigh

80lbs is 36kg. That seems on the low side to me. That diagram is just showing where the aluminium honeycomb is going to be positioned for FEA and manufacture. It excludes the weight of suspension and other mounting inserts, rohacell core, carbon weave and resin (sandwiched together in pre-preg), which depending on the number of layers will add significant weight. 70-80kg total would be more like it. The monocoque weight has been increasing in recent years due to improved penetration protection around the suspension arms.

EDIT: a quick google shows scarbs quoted 70kg back on 2006

Thanks, OK so the 80 lbs or 36 kgs is simply the weight of the aluminum honeycomb, not the weight of the overall monocoque. The overall weight would be ~ 70 kg or slightly more due to increased penetration protection, etc.

I believe so. I also found that the Dallara DW12 monocoque is 81kg (or 179lbs) so close to 70kg for F1 seams reasonable.

Proposed Lotus-style fork nose, very similar indeed to the Lotus unit but with the longer section on the left.
