Fuel efficiency

The LiquidPiston X2 rotary engine boasts a thermal efficiency of 75 percent

The internal combustion engine (ICE) has had a remarkably successful century and a half. Unfortunately, it’s notoriously inefficient, wasting anywhere from 30 to 99 percent of the energy it produces and spews unburned fuel into the air. Last week, Gizmag interviewed Dr. Alexander Shkolnik, President and CEO of LiquidPiston, Inc. about its LiquidPiston X2 - a 40-bhp rotary engine that burns a variety of fuels and requires no valves, cooling systems, radiators or mufflers, yet promises a thermodynamic efficiency of 75 percent.  Read More

Fraunhofer's cylinder bore hole honing tool

You may think that the pistons in your car’s engine slide in and out of the cylinder bore holes smooth as silk, but according to researchers from Germany’s Fraunhofer Institute for Machine Tools and Forming Technology, the process could be smoother. If it was, your car would burn less gasoline, and require less oil for lubrication. Well, those researchers have developed an engine-building tool, designed to minimize engine cylinder friction.  Read More

The Lamborghini Aventador LP 700-4

Lamborghini’s Aventador LP 700-4 is doing something that supercars aren't exactly famous for – it’s saving fuel. Not satisfied with a car that can do 0 to 100 km/h (0-62 mph) in 2.9 seconds and hit a top speed of 350 km/h (217 mph), Lamborghini has fitted the Aventador LP 700-4 with a fuel economy system that includes an automatic engine start/stop and a cylinder deactivation system.  Read More

The 2013 Toyota Avalon (Image: Toyota)

With U.S. mileage standards set to rise to 54.5 miles per gallon by 2025, Carmakers are working flat out to make their vehicles burn as little fuel as possible. One approach is to develop new drivetrains based on hybrid or all-electric technology, but regardless of the platform, weight reduction remains very much a part of the equation. Toyota is pointing to its 2013 Avalon as an example of its progress on this front, having designed the mid-size sedan with 110 pounds (49.89 kg) less weight than the 2012 model.  Read More

Airbus envisages future passenger aircraft taking off with the assistance of a catapult-li...

A new report drafted by Airbus as part of its “Smarter Skies” initiative sees the aircraft manufacturing company looking toward 2050 and beyond, in order to consider what can be done to meet the expected growth in future air travel sustainably. The ambitious plans put forward include assisted take-off, free-glide landings, and aircraft flying in formation.  Read More

GasPods are tiny stick-on airfoils, designed to lower your vehicle's wind drag

Chances are, at some point you’ve seen vehicles that were designed with streamlined little knobs on their hoods or roofs, to improve their aerodynamics. While such features have been shown to work, they generally haven’t been available as an aftermarket product. Now, however, if you want those knobs on your car, you can have them – in the form of GasPods.  Read More

NanoSteel's nano-structured steel materials can help automakers such as GM to make lighter...

With fuel costs continuing to rise, the search is on for ways to make cars lighter and improve fuel efficiency, without compromising strength and safety. NanoSteel, a Rhode Island-based company recently announced the development of new nano-structured advanced high-strength alloys whose strength and ductility meet automotive structural demands. The company plans on marketing its sheet metal products in 2013 and has recently received investment from GM suggesting they could soon be appearing in production vehicles.  Read More

Ford's C-MAX Hybrid gets the same fuel economy in the city as on the highway

Ford definitely appears to have Toyota in its sights with its 2013 C-MAX line. Having already revealed the C-MAX Hybrid will be cheaper than Toyota’s Prius v, the U.S. automaker is now boasting that its hybrid utility vehicle beats the Prius v in the fuel economy stakes by up to 7 mpg (33.6 liters/100 km). It is also the first vehicle to offer the same fuel economy rating in both city and highway driving.  Read More

Aston University's hydrogen-fueled, flat-pack cardboard and plywood creation

Aston University's entry into this year's Shell Eco-Marathon may look a little low-tech, but that didn't stop the hydrogen-fueled cardboard and plywood flat-pack car from scooping the Eco-Design award at the European event, held in Rotterdam in May.  Read More

Honda has announced that its new Fit EV has received a combined adjusted Environmental Pro...

As the promised summer 2012 California and Oregon rollout of Honda's 2013 Fit EV approaches, the battle for "fuel" efficiency supremacy has begun. Honda has announced that its new battery electric vehicle has received a combined adjusted Environmental Protection Agency mile-per-gallon-equivalency rating of 118 MPGe (1.99 L/100km equivalent), nudging it ahead of all of its nearest rivals in the emerging EV market.  Read More
