The average cost for Detroit's Big Three automakers to meet the proposed fuel efficiency targets of 31.6 miles per gallon by 2015 has been pegged at $30.6 billion. In contrast, the average cost for the Japanese automakers sits at less than half that amount at "only" $14.85 billion. These numbers come courtesy of a recent study by Global Insight. In a real shocker, General Motors alone is expected to pay out $15 billion alone. Why the disparity? Simple: the Japanese brands already offer more fuel

With American drivers nervously eying $4 gallons of gas, another group of people is getting that sinking feeling in the stomach as well: car dealers. Automotive News (subs req'd) says that Chrysler co-President Jim Press set the stage for 2008 car sales by saying, "This year is going to be a pretty severe year."

Perhaps this story has more to do with the proliferation of the Internet than it does about green car trends, but here we go anyway. We all know that you can check fueleconomy.gov to find out what the fuel mileage of current and past cars is or was. Anybody who carries an internet-capable cell phone in their pockets also knows that navigating sites which are not optimized for mobile browsers is rather difficult from the average phone or internet tablet without a full browser. With that in mind,

Ford has decided to make some mid-year running changes to bump the mileage on their biggest vehicles. The SuperDuty pickups generally have a hard time cracking the double digits but then they are designed as work trucks meant to haul large heavy loads. Nonetheless, anyone using one of these beasts to earn a living is bound to have concerns about the rising cost of fuel. Single rear wheel F-250 and F-350 models with the 6.4L diesel get lower final drive ratios going from 3.73:1 to 3.55:1. Combine

For some time now General Motors has been planning to shift their big sedan models such as the Chevy Impala from their current front wheel drive configurations back to rear wheel drive. The Zeta platform that will form the basis of the new Camaro and Pontiac G8 was supposed to spawn a new Impala in 2010. However the shifting sands of oil prices and new fuel economy regulations may cause a shift in plans. While the current Impala sold almost 300,000 units last year some projections for a new rear

We've talked before about the seemingly inexorable increases in engine power output while fuel economy is stagnant or moves up only slightly and of course European manufacturers are not immune. Audi has just bumped the output of 3.0L TDI V-6 in the Q7 from 233 hp to 240 hp. At the same time they did improve the mileage from 22.4 to 24.0 mpg (US), which is certainly impressive for such a heavy SUV. We should be getting the Q7 TDI here in the US later in 2008.
