    Efforts by automakers to increase fuel efficiency and reduce carbon emissions have intensified in recent years as emission rules have tightened and the effects of climate change are better analyzed.

The latest effort to make engines more fuel-efficient will come from Nissan's premium brand, Infiniti, in the form of itsnew variable-compression turbocharged (VC-T) inline-4 engine.

  • 2015 Audi A8 L W12 Exclusive Concept

    There's a reason people like big, multi-cylinder engines and it isn't just about the noise they make or how much power they produce. It's also to do with smoothness. And it's one reason some people are worried about the latest trend for downsized four-cylinder units, as they begin appearing in larger vehicles. If Audi's next generation four-cylinders come to fruition, we may not have to worry. The German firm has patented a four-cylinder engine which promises refinement and smoothness on-par with six and even eight-cylinder engines. According to Autocar (via Motor Authority), the patent...

  • 2011 Tesla Roadster Sport 2.5

    Let us run a few engines past you. A warbling flat six. A growling V8. The howl of an inline four changing cam profiles. The smooth buzz of a rotary. How about some names now? Hemi. Vortec. Powerstroke. VTEC. Renesis. Ecoboost. Noticing a pattern? The first list is clearly engine layouts, and the second are trademarked brand names for particular motors. The similarity amongst them all is that you could probably link every single layout and name with a particular car company, or sometimes even with a particular model. Rotaries for example have been synonymous with Mazda for many years now, and...

    One of the benefits of the electric vehicle experience is the near instantaneous torque at your disposal when you prod the right-hand pedal: no shifting, no "kickdown," just smooth power. So why exactly would the 2011 Nissan Leaf electric car have a "passing gear"? On any electric car, the torque starts to level out the faster you go. And unlike a conventional geared combustion engine car there are no gears to change down into to increase your torque and power at a particular road speed. In most situations though, plug-in electric cars like the 2011 Nissan Leaf and 2011 Chevrolet Volt should...
