Not a full review yet, but the July 2012 issue of Consumer Reports has a "First drive" sidebar. "We've been able to go 12 to 15 miles solely on electricity, but we have to be gentle with the throttle and stay below 60 mph."The gas engine kicks in with even moderate acceleration, so unlike the Chevrolet Volt, you can't drive it completely gas-free. That could limit its appeal to people who want to maximize their electric-only driving."This is a sidebar to a "Best ways to save gas" article, which lists the Volt at the top of the hatchbacks/wagons category of recommended cars for fuel economy, due to CU's "real world" MPG scores of 61 combined, 99 MPGe and 32 mpg. My personal reaction: Being "gentle on the throttle" has certainly dominated my first weeks of PIP driving. It's intellectually fun and probably a lot safer than my old habits. After the first tank, for comparison, I will switch from Eco to power mode, turn off the EV miles remaining display, and "just drive it."
