The Lexus LFA's frame is made from an in-house designed and manufactured carbon fibre-reinforced polymer (CFRP) centre monocoque with aluminium front and rear subframes. The subframes, which can be removed and replaced minimising potential repair costs, are joined to the monocoque using a newly developed aluminum flanged collar designed to create a stronger joint. According to the manufacturer, the quality of the CFRP material matches that of aeronautical grades and is woven by a laser monitored circular loom, one of only two in the world. Overall 65% of the vehicle's total body mass is CFRP material while the remaining 35% is aluminum. Manufacturer data indicates that the use of CFRP saves over equivalent aluminum materials.
