Why not direct injection?

A giant gulp of water can ruin any engine's day. It doesn't matter if the fuel is injected before or after the intake valve.

The alloytec 3.6 liter variable valve timing double overhead cam direct injection engine platform was developed by the Holden Group; GM's wholly owned Australian sourced engine development.
The GM sourced global alloytec engine first debuted in the United States in the 2003 Cadillac CTS as a 255 BHP port fuel injected 3.6 liter platform. DI was later introduced to the alloytec in 2008 increasing current bhp to 304.
Global variants are used by Holden, Saab, Alfa Romeo, and GM.
This little alloytec V6 engine is actually bored to 4.0 and currently sleeved to a 3.6 liter capacity for U.S. distribution as the LY7 crate motor.
The engine itself is manufacted in St. Catherines, Ontario and will support in excess of 400 BHP in both diesel and petrol variants as well as NA, turbocharged and supercharged platforms as well.
The alloytec is GM's only global engine and its little darling in terms of being able to reduce parts in the GM global parts bin.

I'd love to see a worked DI LS3 but that's just not going to happen, I think we're going to see a smaller displacement less torque but similar horsepower engine fitted with DI and slightly better mpg
