Translogic episode 5.3 takes a look at the 2011 Chevy Volt and what makes it tick, and next week we'll get behind the wheel to tear up GM's Milford Proving Grounds in our in-depth road test. But first, let's clear up a few issues. With the Volt just months away from going on sale late this year, consumers still have plenty of questions about how it works and why General Motors built it the way it did.

The National Development and Reform Commission in China recently added 71 models from 16 different automakers to the approved list of vehicles that qualify for subsidies based on fuel efficiency alone. All of the qualifying vehicles are fitted with engines no larger than 1.6 liters and consume fuel at a rate of at least 20 percent below the average vehicle sold in China. Models such as the Hyundai i30 pictured above, will receive a subsidy of 3,000-yuan, which comes to a laughably small $442 (U.

The Formula One Teams Association (FOTA) wants to cut cut its total carbon emissions by 15 percent within three years and double the efficiency of its race engines within five years. FOTA commissioned an analysis by Trucost to determine its total life-cycle emissions from all operations. As it turns out, the race cars actually only account for about one percent of F1 carbon emissions, with half coming from materials the teams purchase. Other significant sources of energy consumption include tran

Once upon a time, in a history not that far removed from present day, automakers descended into design madness by equipping all of their vehicles with federally-mandated rubber bumpers wide enough for a Boeing to land. It was a dark time that eventually saw the svelte chrome bumpers of old banished for good. Now it looks like one MIT graduate would like to see similar technology come to small cars in the form of side bumpers.

At its annual technology day in Ingolstadt yesterday, Audi revealed more information about its redesigned 3.0-liter V6 turbodiesel engine. The refreshed powerplant will be appearing in an array of products from the Volkswagen Group this year, including the new Touareg, Cayenne and the Porsche Q7 update.

For those of you who hail from Canada or the Northeast United States, Tim Hortons needs no introduction. For the rest of our readers, a very brief history: picture a small-town doughnut shop that, over the last 50 years or so, has morphed into a combination Dunkin' Doughnuts/Starbucks/McDonalds that rules the Canadian fast food industry with an benevolent iron fist.

Affordability as the watchword Tuesday as automotive engineers at the SAE World Congress discussed how to meet the new 2016 corporate average fuel economy standards. Automakers will have to get their fleets to an average of 34.1 miles per gallon (35.5 equivalent with other factors for the EPA CO2 limits). Most automakers are already well on their way to this level with their next-generation designs. However, to do it they will have to make improvements to virtually every model in the entire flee

Why does mileage drop in winter?

This week's Greenlings topic came to us from another reader tip. Don asked why his fuel economy suffers so much in winter weather. In his own experience, mileage drops about 10 percent when the temperatures go from the 60-70 F range to near freezing. This is consistent with our own experience and in fact we've seen even bigger drops than that when testing hybrid vehicles in winter conditions.

In typical Honda fashion, its premium Acura division will take a different path and has decided not to get sucked into a power race with its rivals. We already knew Acura had shelved plans for a larger V8 engine and a rear wheel drive platform. Product planning manager John Watts told Automotive News that the brand will instead focus on doing what needs to happen to meet the 2016 fuel economy standards which will be "tough."
