You may have heard that you can’t have your cake and eat it, too. But that may not be true, at least when it comes to your new car’s engine.

With gas prices continuing to rise, manufacturers have shifted away from the big engines in favor of smaller engines that produce improved mileage. At the same time, consumers don’t want to lose the power they were accustomed to getting from previous models. So, how do manufacturers give consumers the best of both worlds?

Ford has responded to this new demand with “Ecoboost”. These new engines boast the same specs in horsepower and torque as their bigger displacement opponents, but with much improved mileage and emissions. Ford is not the only one doing this either, other companies have also started utilizing this engine setup, under different names, for their new models. So what is the secret?

The answer is quite simple: turbochargers. A Turbocharger uses exhaust gasses to spin its turbine and suck more air into the engine. That, along with more fuel, will create bigger explosions in the cylinder and therefore more power will be generated. A Ford F-150 equipped with an “Ecoboost” engine has a twin-turbocharged V6 instead of the traditional V8. What the turbocharger allows the engine to do is act like a V6 and get mileage similar to one while driving around. Most of the time you don’t need full power from the engine, such as when you’re maintaining your speed or during deceleration. When you actually do need some power, the turbocharger can spool up and provide that extra boost in power to make the engine perform similarly to a V8. This equates to a engine that will get better mileage and perform the same as a bigger, naturally aspirated, competitor.

Engines similar to Ford’s “Ecoboost” are being used in various new cars. Dodge recently released its new Dart, which on certain models, comes equipped with a 1.4L MultiAir Turbo engine option. The Chevrolet Cruze is equipped with a 1.4L Turbo “Ecotec” engine option. Even luxury manufacturer BMW has switched out the inline six in their 3 series base models for 2.0L Turbo engines. These cars all boast similar performance with much improved mileage to their predecessors.

Fuel mileage is the name of the game when it comes to selling cars in today’s market. Each year more and more small engine turbos show up on the market. If you’re in the market for a new vehicle that gets better mileage than the one you drive now, be on the lookout for setups like these.
