Made almost entirely of aluminum and featuring direct injection, variable valve timing on both intake and exhaust sides and a high-efficiency turbocharger, the new-for-2013 1.8 liter gasser from Alfa Romeo and Fiat Powertrain Technologies is one of those downsized engines that combines all of the ...

Four cylinder engines have replaced sixes as the engine of choice for U.S. consumers, powering 43 percent of light vehicles sold in the first six months of 2011, according to IHS Automotive. Back in 2005, V6 engines were found under the hood of 43 percent of vehicles sold, but rising fuel prices ...

Multi-fuel capable cars have been around for quite some time. Case in point, five years ago we reported on a Volvo prototype that could burn five different types of fuel. But a new project from Chrysler is aiming to do something that none of these existing flex-fuel vehicles can pull off: an ...

General Motors announced that it will invest $100 million to retool and enhance its GM Components Holdings Rochester Operations facility in Rochester, NY. The retooling will enable The General to manufacture its next-generation, fuel efficient small block car and truck engines. Cathy Clegg, GM's ...

Researchers at Michigan State University (MSU) have prototyped a potential game-changing, gasoline-burning engine that requires no transmission, crankshaft, pistons, valves, lubricants or cooling systems. The so-called Wave Disk Generator (WDG) could substantially improve the efficiency of ...

Along with the introduction of its new Energy dCi 130 diesel engine, Renault saw fit to create a pretty snazzy video to show off some of the technology hiding in this new powerplant. The video offers the unusual ...

Back in 2008, soaring gas prices sent car buyers in search of efficient four-cylinder vehicles and, as the numbers show, sales of V6 and V8 engines dropped from 63.9 percent to 57.1 percent when gas prices spiked. Though elevated fuel costs may have triggered the increased demand for ...

Engine downsizing is considered an effective method to reduce emissions and improve fuel efficiency. The basic concept is simple: replace a larger engine with something that displaces less and, typically, packs a turbocharger to make up for any lost power. One impediment to engine downsizing is ...

The words "diesel" and "Bentley" have flirted for some years now, but it never gets beyond that initial stage. Bentley isn't against oil burners, but its customers in the U.S. and Japan aren't ready to connect the two, and that makes the issue a non-starter. Not only that, but Bentley CEO ...

Along with eight-cylinder engines and manual transmissions, six-cylinder motors appear to be on the outs, relatively speaking. In the first quarter of this year, USA Today notes that four-cylinder lumps made up 46.5 percent of new car sales, almost a five percent jump over the same period last ...
