...when I called GM "Customer Assistance" about our 2011 Chevrolet Cruze LTZ, asking "why?" it didn't have their Spark Ignition Direct Injection (SIDI) like their 2.4L and V6 engines did, the reply was: "...we could reach our MPG goal without it." DUH?
...FWIW, the 1.8L engine in my 2009 Pontiac Vibe (nee' Toyota Matrix) is SIDI.
