Use of a variable compression ratio (VCR) could be one technology approach to reducing fuel consumption in highly boosted (e.g., downsized, turbocharged) gasoline engine, as operating an engine with higher compression ratios at low load can increase fuel economy compared to operating an engine with fixed compression ratio.

If you spend most of the week huddled in a conference room or behind a computer, spend the rest of the day indoors, perhaps an expensive sports car is not your ideal possession. Our focus is on vehicles that offer the best fuel economy in their class, which leads us to emphasize electric cars, plug-in hybrids, hybrids and diesels.

As with any alternative fuel, be it CNG, LPG, electricity, hydrogen or E85, one of the challenges facing its adoption is both the availability of the fuel as well as the mechanics of refueling. We’ll set aside the business challenges facing alternative fuel providers.). A blue handle would indicate 3,000 psi.
