The LF1 reportedly suffers from a lack of low-end torque. It's fine for most people who use the engine for commuting, but folks who are used to a torque-y performance car find that the engine revs too high before reaching peak torque, which kills fuel economy. In fact, the 3.0L and more powerful 3.6L in the CTS achieve the exact same fuel economy ratings.
Holden supposedly came up with a fix for it but it doesn't meet EPA guidelines or something.
