Pistonheads had a review of the engine, from the article -
“Direct injection definitely gives you an edge for economy, which is why so many people use it," Wood explains, "but that wasn't really the priority here, and if you want power rather than economy port injection is slightly better, and it also meant we didn't need a GPF."
Interesting comment, so bring back old fashioned squirters and do away with power sapping GPFs and their weight.
