Fuel efficiency

The US Department of Energy will be using fuel cells to power the refrigeration units of f...

The refrigeration units used in cold transport trailers are typically powered by small diesel engines, which use up non-renewable fuel and release greenhouse gases, just like their big brothers. The US Department of Energy, however, is looking into an alternative. As part of a two-year pilot project, it’s equipping four such trailers with clean-running hydrogen fuel cells.  Read More

The Elio 3-wheeler

Scheduled to sell for less than half the price of the current cheapest car in America, the Elio is a 3-wheeled "car" that hopes to shake up the automotive world. It eschews the trendy electric powertrain for a small gas system, but thanks to its small, light, aerodynamic design, it promises to keep drivers away from the gas pumps for as long as possible.  Read More

The Automatic Link plugs into your vehicle's diagnostic port, and communicates with an acc...

Perhaps you’ve got a decent, several-year-old car that you’re still happy with, but that you wish had some of the helpful computerized features of today’s newer models. Should that be the case, don’t go trading in your ride just yet. The Automatic system accesses your existing car’s onboard computer, then displays driving and diagnostic data on your smartphone’s screen. It could potentially save you money, trips to the garage, and even 911 calls.  Read More

ADVENT is a joint project of GE and the U.S. Air Force

Engineers at GE think they could have a revolution on their hands, thanks to the new jet engine they've been working with that runs hotter than any of its predecessors. When combined with some other design changes, they figure their so-called ADVENT (short for ADaptive Versatile ENgine Technology) design could improve fuel efficiency by as much as 25 percent, extend flying ranges by 30 percent, and boost thrust up to 10 percent over contemporary engines.  Read More

Cross-section of the GE ADVENT engine design

GE Aviation is developing a revolutionary new jet engine that aims to combine the best traits of turbojet and turbofan engines, delivering supersonic speed capability and fuel efficiency in one package.  Read More

The 1.6-liter i-DTEC engine

Honda apparently wants to show that good things come in small packages, so it's announced that it will be installing its 1.6-liter i-DTEC diesel engine in the 2013 Civic manufactured at the company’s facility in Swindon, U.K. Specifically designed for the European market, the 1.6-liter i-DTEC is the lightest in its class, yet puts out 120 PS (118 bhp) and 300 Nm (221 ft-lb) of torque.  Read More

Ford's newly-updated Transit Connect Wagon

Ford has just announced an update to its 7-passenger people mover, the Transit Connect Wagon. Generally, such large vehicles aren't know for their stellar fuel efficiency, but the automaker is looking to break that trend with this 30 mpg (7.8 l/100km) vehicle.  Read More

Hyundai Motor America and Kia Motors America have overstated the fuel economies on the window stickers of some 900,000 automobiles from 13 models sold since late 2010, The Detroit News reports. An investigation by the U.S. Environmental Protection Agency (EPA) found that the results of its own tests did not always tie up with the companies' claimed mileages, and as a result Hyundai and Kia are lowering fuel economy estimates on what is reportedly a majority of current models.  Read More

Retrofitting engines on existing Navy ships, like the USS Arleigh Burke pictured here, wit...

With around 430 gas-turbine engines on 129 of its ships burning about US$2 billion worth of fuel every year, the U.S. Navy is examining the potential of using Rotating Detonation Engines (RDEs) to improve fuel consumption and cut costs. Researchers at the Naval Research Laboratory (NRL) estimate that retrofitting RDEs to its fleet could save the Navy approximately 300 to 400 million dollars a year.  Read More

The mountain bike version of the Energy Return Wheel, being put to the test

Puncture-proof tires that incorporate a flexible internal matrix instead of air are nothing new, in and of themselves. In the past several years, we’ve seen prototypes from the likes of Michelin, Amerityre, Goodyear and Bridgestone. Colorado-based Britek Tire and Rubber has also been developing something similar, known as the Energy Return Wheel. While the ERW is intended mainly for cars, the company recently released a video showing a prototype set of the wheels in use – on a mountain bike.  Read More
