"Though it is neither turbocharged nor supercharged, it has direct fuel injection as well as supplementary fuel injectors in the intake manifold. This facilitates a sky-high 12.5-to-1 compression ratio in the combustion chambers. Throw in equal 86-millimeter bore and stroke dimensions for the pistons, as well as variable valve timing, and you get a smooth-running engine that eagerly leaps to its 7,400 redline."
