Wondered why Hamilton could accelerate so fast with such little wheel spin? Why he can start so well? Well the answer lies in McLarens steering wheel. It is believed they almost have a manual traction control system on their wheel. Spotted by the Telegraph as follows:
"McLaren's steering wheel features four paddle levers rather than the
usual two. The upper two are conventional gear-change paddles, one for
upshifting, one for down. The lower two allow different engine torque
settings to be chosen. Using two fingers at the same time allows the
car always to have the most favourable engine torque setting for each
gear, thus giving the driver a tool for limiting wheelspin out of slow
corners without then suffering a reduction in power in the higher
gears, where wheelspin is not an issue. The rules stipulate that any
change in torque settings cannot be triggered by the same driver input
as a gear change. Having two separate levers gets around that rule,
while still allowing the change of gear and torque setting to take
place simultaneously. This is part of McLaren's current performance
superiority over Ferrari."
