More torque at low revs means better drive out of corners, so the shape of the piston and connecting rod, as well as valve timing, is optimized for combustion consistency and thereby exhaust efficiency at lower revs. Colour: Extreme Red

More torque at low revs means better drive out of corners, so our engineers focused on the shape of the piston and connecting rod, while optimizing valve timing to help prioritize combustion consistency and thereby exhaust efficiency at lower revs. ...
