The seat shells are also made of carbon fiber, and with minimal padding, weigh just 10.5 kg each. They're fixed in place but can be adjusted in the workshop. Carpeting can be fitted, but even that's low weight. Given this obsession with shaving weight, it strikes us as a bit odd that there's so much glass: the windshield is even deeper than it is wide, and the roof is made of glass, too. That does appear, however, to give the McLaren P1
a fighter jet-like canopy cockpit, and promises to improve outward visibility to help the driver muster all the P1 has to offer...and hopefully keep it on the straight and narrow in the process.
