• 2017 Volvo S90 T6 AWD Inscription

    Automakers may gradually be putting more emphasis on plug-in electric cars and conventional hybrids, but they are far from done with plain old internal combustion. Over the past few years, automakers have applied more technology to a wider array of cars in order to boost their efficiency to meet stricter fuel-economy standards. The most popular manifestation of this is downsized turbocharged engines, which aim to produce similar power to larger naturally-aspirated engines with the better fuel economy of their lower displacement. DON'T MISS: VW suggests engine downsizing is done; emissions...

    2014 Ford Fiesta EcoBoost: Gas Mileage Test Returns 40 MPG

    As a general rule, we like small cars, and small cars with small engines. Eighteen months ago, when we first drove prototype versions of the 2014 Ford Fiesta EcoBoost, we knew we'd be eager to get our hands on the little subcompact with the turbocharged three-cylinder engine for a longer drive...

  • 2014 Ford Escape SE 1.6-liter EcoBoost, Catskill Mountains, NY, Nov 2013

    The Ford Escape, entirely redesigned for 2013, is one of the best-selling entries in the popular category of compact crossover utility vehicles. The real-world gas mileage of the latest Escapes, however, does not quite seem to equal those cars' combined EPA ratings. Ford has put a great deal of effort into engineering its EcoBoost four-cylinder engines, which use direct injection and turbocharging to make smaller engines produce the same power as the larger ones it previously used. 2.0-liter EcoBoost: struggle to hit 24 mpg When we tested a 2013 Ford Escape with the 2.0-liter EcoBoost engine...

    Five Turbocharged Green Cars You Need To Drive

    There was a time when a turbocharger under the hood meant one thing and one thing only: that the car you were driving was a performance-oriented, sporty beast with that oh-so-addictive turbo whine. Today, the turbocharger has become the biggest thing in green car technology since the hybrid...

    Turbos Grow Much Faster Than Hybrids In Quest For MPG

    There's a quiet revolution going on in the auto world, one that isn't as trendy as plug-in cars or hybrids: turbocharged engines. Cheaper to build and buy than hybrid systems, they offer great gas mileage and great performance. In some cases, such as the 3-cylinder 2014 Ford Focus 1.0-liter...

    Smaller Engine Watch: VW 1.4 Turbo To Replace 2.5 Five In U.S.?

    We've been saying for a long time that one way carmakers will meet new, tougher gas-mileage rules is to make their engines smaller but more efficient. Ford's EcoBoost lineup of direct-injected, turbocharged engines is one example, from a 3.5-liter V-6 used in full-sized pickups all the way down to...

  • Tiny Darth Vader uses the force on a 2012 Volkswagen Passat

    If you remember Volkswagen’s Super Bowl advert from earlier this year involving a pint-sized Darth Vader, its 2011 Passat had a particular affinity with the dark side of the force. But as of 2013 the evil Pasatt will have a nemisis in the form of the 2013 VW Jetta Hybrid, complete with a noticiably greener tinge thanks to the power of a 1.4 liter hybrid drivetrain. According to Car and Driver, the hybrid Jetta will be officially unveiled at the 2012 Detroit Auto Show with sales starting some time by the end of 2012. VW plans to market the gasoline electric hybrid as a sports hybrid...

    How Smaller Engines Offer More Power: Superchargers Vs Turbos

    Turbochargers have been with us in volume production only since the Seventies, but superchargers have a long and honorable automotive history. They were used on the Blower Bentleys that won Le Mans 80 years ago, and have appeared ever since on high-performance engines, often larger ones. A boost...

  • 2011 Chevrolet Cruze Eco

    Used to be that turbos were used in performance cars, from the Saab Turbos of the late Seventies to BMW's current range of twin-turbo sixes. These days, the little air pumps more often make smaller engines perform like bigger ones to give fuel economy. In brief, a turbocharger uses exhaust gases to drive a turbine that pumps more air into the intake manifold, so more gasoline can be burnt for greater power. We write about this engine downsizing theme a lot, and we're hitting it again because our colleague Bengt Halvorson just looked at the 1.4-liter turbocharged four that GM fits to the...
