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.

BCG comparison of the CO 2 reduction potential and cost of different technologies. Assuming the China government remains committed to EVs, BCG expects that these vehicles will represent 7% of new vehicle sales in 2020, supported by car buyers’ enthusiasm for the technology and the country’s high gasoline taxes.

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. It is much more than that.

Environmental Protection Agency (EPA), which stewards the RFS, had repeatedly downsized the targets by nearly 25 percent. A more recent study found that, since the program coaxed farmers into using more land for corn cultivation, RFS biofuel wasn’t actually any less carbon-intensive than gasoline. By the mid-2010s, the U.S.
