Here's an item, from washingtonpost.com, about developments in non-hybrid high efficiency gas cars. Given all the discussion on Prius Chat about grill blocking, I've copied down to the fourth paragraph, where this is discussed ont the non-hybrid Chevy Cruze. I wonder if it would help to have it built into the Prius in future years? Gas-powered cars start matching hybrids Peter Whoriskey | 2:44 p.m. ET The new Chevrolet Cruze Eco can reach eye-popping fuel economy levels of more than 50 miles per gallon on the highway, which even in this era of hybrid-electric car achievements stands among the best. But here's the real trick: The Cruze Eco is neither a hybrid or electric. It runs instead on that "old" technology, the conventional gasoline engine. Although alternative technologies have garnered much more hype and significant federal subsidies, the best immediate hope for restraining the nation's fuel consumption might be some new cars that, though powered by conventional engines, nevertheless run very efficiently because they have been stripped of unnecessary weight, streamlined to move through the air smoothly and equipped with gas-sipping engines. This year, General Motors, Ford and Hyundai have begun selling cars with conventional engines that achieve 40 mpg or more on the highway, exceeding the fuel efficiency of some hybrids, because their mechanics and shapes have been optimized. To achieve the efficiency of the Cruze Eco, engineers dropped its weight by 200 pounds, installed shutters to close off part of the grill at higher speeds to reduce wind drag, added a rear spoiler, cut the car's height by a centimeter and adopted an efficient turbocharged engine.
