Auto Stop-Start technology that shuts off a vehicle’s engine when it comes to a stop to save fuel is a standard feature on many hybrid and electric-vehicles (EVs), including Ford’s Fusion Hybrid and Escape Hybrid. Ford has now announced its Auto Start-Stop system will be added to conventional cars, crossovers and SUVs in North America from 2012.  Read More

The HybriDrive series propulsion system developed by BAE Systems is currently enhancing the fuel efficiency and cutting emissions on more than 3,000 transit buses in cities around the world, including New York and London. The system is specifically suited to the driving patterns of urban transport, which involve low average speeds and frequent stopping and starting. To meet the needs of applications that have higher operating speeds and less frequent stops, BAE is developing a new parallel hybrid propulsion system to bring the fuel-saving benefits of its technology to medium and heavy-duty trucks.  Read More

The new label provides relevant information for buyers of EVs and hybrids

With hybrid and electric vehicles appearing in more and more automobile showrooms around the world, the traditional fuel efficiency measure of miles per gallon (MPG) alone just doesn’t cut it anymore. With cars able to be powered by electric power alone or a combination of electric and gasoline, new measures are needed to better inform consumers when buying a new car. To this end, General Motors (GM) and the Environmental Protection Agency (EPA) have teamed up to design a new window label for the Chevrolet Volt that has more information than any EPA label before it.  Read More

The Urbee's entire body was 3D printed (Image: Kor Logic)

In the early 20th century Henry Ford revolutionized automobile production with the introduction of the assembly line for the iconic Ford Model T. Now, almost a century later, a car has been produced using a process that could prove just as revolutionary – 3D printing. Code-named, Urbee, the streamlined vehicle is the first ever to have its entire body, including its glass panel prototypes, 3D printed with an additive manufacturing process.  Read More

The Edison2 team, with Oliver Kuttner beside the Very Light Car

The Edison2 team took away US$5 million for winning the Mainstream class of the Automotive X-PRIZE last week with its 100+ MPG car of the future – Very Light Car #98. Gizmag caught up with team leader Oliver Kuttner after the ceremony to find out what's next for Edison2.  Read More

The fuel economy record-setting Avion automobile

Back in 1984, Craig Henderson and Bill Green built a one-of-a-kind super fuel-efficient car called the Avion. In 1986, it set the Guinness world record for fuel economy by averaging 103.7USmpg (2.27L/100km) while driving from the Mexican to Canadian borders. Unlike most autos from that era, the Avion is still on the road... and breaking its own records. In October 2008, Henderson and Green achieved 113.1mpg (2.08 L/100km) on a 263-mile (423 km) trip in the US Pacific Northwest. Then, this August 29th, they departed from Blaine, Washington (adjacent to the Canadian border) and drove 1,478 miles (2,379 km) to the Mexican border. They used just 12.4 US gallons (46.94 L) of diesel and set a new record of 119.1mpg (1.97L/100km).  Read More

An exploded view of the Chevrolet Cruze's air shutter system

The Honda Civic hybrid gets approximately 45 mpg on the highway, while the similarly-sized 2011 Chevrolet Cruze Eco gets 40 mpg. That's pretty decent on the Chevy’s part, considering it isn’t even a hybrid. Of course, because it isn’t a hybrid, that means it doesn’t sport a hybrid’s price tag - the Cruze Eco will start at $US18,895, as opposed to the Honda’s $23,800. So, how is it possible for a combustion-engined car to almost match a hybrid’s fuel efficiency? Well, lowering the weight and the ride height help a bit, but according to Chevrolet, the real reason lies in the car’s unique front air shutter system.  Read More

Aptera competes in the Range Test event in the Alternative Class at the Automotive X PRIZE

It's very much down to the pointy-end for the remaining twelve teams in Progressive Automotive X PRIZE with the finals stage underway at the Michigan International Speedway. As we write this article teams are taking part in the critical range test where they must achieve 100 miles without charging or refueling (200 miles for the mainstream class) – perhaps the most challenging hurdle remaining for those still in the running for a share of the $10 million prize.  Read More

Minix wing tip device promises 6% gain in fuel efficiency for airliners

Fuel consumption and greenhouse gas emissions are huge priorities in the aviation industry – passenger airliners chew through amazing quantities of fuel. Take the Boeing 747, which guzzles somewhere around a gallon of jet fuel per second – it's clear that a percentile improvement in fuel consumption can make a huge difference to costs at the end of a long-haul flight. That's why the Minix wing tip deserves close scrutiny. It replaces the tilted winglets at the tip of an aircraft wing, can be retrofitted to any airplane, and smooths out the wing-tip vortex, reducing the aircraft's wing drag. Minix claims the design is five times more effective than a regular winglet and can save as much as 6% on an aircraft's energy costs. For a commercial Boeing 747, that equates to a saving of around 600,000 gallons of fuel per year, per aircraft. Food for thought.  Read More

A five year Shell Eco Marathon fuel efficiency record has been smashed by a team of French students. Team Polyjoule broke the record on the first day of the event by recording an astounding result of 4,414 kilometers on the equivalent of one liter of fuel (that's 10,382 mpg). The team then went on to break its own record by a further 482 kilometers. But the students still expect even more from their hydrogen fueled vehicle and are already looking toward next year's Marathon.  Read More
