PUMP IT UP

摘要

It is a simple equation - the more air and fuel you pump through an automotive engine, the more power it can produce. Because the history of American automobile production has revolved around large displacement power plants that make gobs of torque and horsepower, there has not been a great outcry for powerful small displacement engines. That is until lately.rnThere are many influences pushing the car-buying public and automakers alike into smaller engines, such as the recent gas price hike, which pushed prices through the $4 per gallon mark, and new emission and fuel economy standards. Yet performance is one factor the public looks for when buying a vehicle and one the automakers use to sell vehicles.
