New Automotive Technology Can Power Larger Cars With Smaller Engines

Increased fuel economy continues to be an important factor in choosing a car. With engine management systems like Direct Injection, automakers are getting a jumpstart on the new rules and designing smaller engines that are able to power larger cars like the Buick LaCrosse.?Using high-tech computing power, engineers are able to inject precise amounts of gas into the cylinders to reduce fuel waste and vary valve timing to increase horsepower. So even large luxury sedans, which once needed V-6’s or V-8’s to move them, are now getting the same power from a 4- Cylinder, while maintaining the 4-Cylinder’s fuel economy.
