as zx5focused mentioned, the difference is that, much like a diesel, direct injection injects fuel into the cylinder, not into the intake air stream leading into the cylinder.

on the upside, it helps cool the air charge and keeps cylinder temps down, the downside is that currently, most direct injection setups run out of oomph at higher RPMs (most likely a limitation of the injectors).

Now if they could toss that engine into my stang, I won't complain.
