It's really about torque. Other things being equal, more cylinders
and more displacement = more torque.

"As an added benefit, putting lighter wheels on the car can increase
your engine's apparent power. Why? Well the engine has to turn the
gearbox and driveshafts, and at the end of that, the wheels and
tyres.

"Heavier wheels and tyres require more torque to get turning, which
saps engine power. Lighter wheels and tyres allow more of the
engine's torque to go into getting you going than spinning the
wheels. That's why sports cars have carbon fibre driveshafts and
ultra light alloy wheels."

I make no pretense of being any kind of expert, but I've recently
read a lot of information from people that consider themselves to be
experts, and I'm just looking for feedback from this group as to how
things might apply that I've read elsewhere.
