Conspiracy theorists have long insisted that automakers could push their vehicles to achieve better fuel economy, and as it turns out, they were right. Of course, it isn't as easy as flipping a magic MPG switch, but automakers are making incremental gains on vehicles even between redesigns. Techniques like changing gear ratios, lowering revs at highway speed and using lower rolling resistance tires are helping drive up efficiency a few percentage points at a time.
For example, the 2009 Cobalt XFE (above) achieves 37 mpg on the highway compared to 36 mpg for the 2008 model with minimal aero and mechanical changes. Ford made similar changes to the 2009 Escape, enabling the Blue Oval's smallest crossover to hit 28 mpg in 2WD four-banger guise. Honda achieved similar incremental improvements when it introduced cylinder deactivation on the 2008 Odyssey. Chrysler will show 1 mpg improvement on the 2009 Avenger and Sebring four-cylinder model, which will bring the Pentastar's midsize sedans to 31 mpg.
In light of the current pain at the pumps, fuel economy is on all of our minds these days no matter what kind of car you drive. That being the case, it might not be surprising to you that the car we're buying are getting more fuel efficient. Don't believe us? The National Highway Traffic Safety Administration has just revealed that the U.S. auto industry set a new record in overall fuel efficiency during the first half of the 2008 model year by averaging 26.8 mpg through March. That's up from an average of 26.6 mpg through the entire 2007 model year.
While this is certainly good news for both consumers and manufacturers that need to meet the government's mandated CAFE standards, the numbers used by the NHTSA aren't really representative of the real-world fuel mileage you should expect to achieve on the road. The testing standards were initially created in 1975 and automakers get certain credits for creating flex-fuel vehicles, which can artificially inflate their miles-per-gallon numbers. Additionally, automakers earn credits for surpassing the CAFE requirements and can carry these credits forward for up to three years. Still, the numbers are somewhat worthwhile when comparing the current model-year with those of the past. Expect to see the year-end numbers set another new record as consumers continue choosing smaller and more fuel efficient models over larger, gas-guzzling choices.
Since the Mazda3 hit the streets in 2004, it's proven to be a very strong contender in the small car segment. The compact sedan and hatch has been winning customers over with great styling, athletic ride characteristics, and equipment that typically isn't found in small cars. Its rich mix of standard features and options has helped keep transaction prices high, which will be very important as the self-proclaimed Zoom-Zoom automaker looks to downsize its lineup and make as much money as possible from every sale.
Mazda will now execute the Mazda3 strategy across its entire line to boost profits while giving customers the standard features they crave. For example, the all-new 2009 Mazda6 will be equipped with disc brakes at all four corners in every trim level while some of the competition continues to use rear drum brakes on their base models. Mazda has already proven that adding standard content can raise transaction prices while at the same time increasing sales, now the Ford-controlled automaker needs to prove that it can accomplish the same feat across its lineup. If Mazda makes all of its vehicles as competent as the Mazda3, that shouldn't be a problem.
As if "shift lights" weren't annoying enough... Nissan's new "ECO pedal" has been engineered to encourage good fuel economy with a servo-actuated gas pedal that will push back on the driver's lead foot when on-board computers detect wasteful acceleration. According to Nissan, vehicles equipped with the ECO pedal, and real-time fuel consumption gauges in the instrument panel, have returned a 5-10 percent increase in fuel efficiency. The Japanese automaker says it has plans to begin installing the ECO pedal in models next year, although there is no word on what models, or markets, will get the system. We're betting it's an option unlikely to show up on the GT-R anytime in the near future.

Besides the introduction of the Dodge Challenger, there has been very little good news coming out of Chrysler lately. Sales are down 22% for the year due to a lineup that's still heavy on trucks and SUVs, but there may be some help on the way as soon as 2009. Chrysler CEO Bob Nardelli has hinted that a fuel efficient new vehicle(s) could debut next year, and platform sharing with other automakers would be behind the quick turn-around. Nardelli says the Auburn Hills-based automaker has re-prioritized its capital in an effort to quickly get to market the fuel-efficient vehicles that the market demands. Debuting even a single vehicle that's more fuel-efficient than anything else in the Chrysler lineup would likely have a big effect in light of the fact that its brands offer some of the least fuel-efficient lineups in the industry.
Nardelli didn't give any details as to which vehicle could arrive ahead of schedule, but speculation is that the Dodge Hornet is on the short list. The handsome Hornet (if it looks like the concept) will be based on the Nissan Versa small car platform, and was originally slated to arrive in Dodge guise in 2010. Chrysler is also rumored to be working on alliances with Tata, Fiat, and Chery, and each automaker has plenty of small, efficient vehicles at its disposal. None of those automakers has a presence in the U.S., though, so a quick turnaround on a platform that hasn't been properly crash tested doesn't seem likely.

If the Prius went mainstream when Toyota bumped production to 280,000 worldwide units per year in 2007, the fuel efficient hybrid is now primed to kick project green to the next level. When Toyota begins producing the next gen Prius, it'll do so with more factory space than ever dedicated to the universal symbol for fuel efficiency, making it possible to produce 480,000 vehicles per year. The Japan-based Tsutsumi factory, which currently builds five different vehicles, will stop making the JDM Wish minivan to allow for more Priuses. Even more Prius capacity will be available beginning in 2010, when the Japanese automaker's new Mississippi plant comes online and begins to produce more of the hybrid.
With the meteoric rise in gas prices, the Prius has gone from a yuppie green statement for politicians and suburbanites to a means for the masses to travel around town without breaking the bank. $4 per gallon gas and a continued lack of competition means Toyota could probably double production again and still sell every Prius it makes.
To feed the insatiable demand for fuel-efficient vehicles, and follow the striking success of the Toyota Prius, the Japanese automaker will introduce a second hybrid-only vehicle in 2009. The all-new model will have a 2- to 2.5-liter engine, suggesting it will be larger than their current popular four-door hybrid (the Prius uses a 1.5-liter gasoline powerplant). The new model will be sold side-by-side with the Prius, Camry Hybrid and Highlander Hybrid. Toyota will also sell a rebadged version under the upscale Lexus brand, where it will join the LS Hybrid, GS Hybrid, and RX Hybrid. Toyota's master plan is to sell 1 million hybrid vehicles annually throughout the world, and considering the market, there's little doubt that the automaker can pull it off. Toyota's next hybrid debut is scheduled for Detroit in January, and we'll be there to cover it.
The already fuel efficient Smart fortwo will soon become even more stingy with the petrol when start-stop technology is employed fleet-wide beginning in October. The start-stop technology, which is called "micro hybrid" by Smart, works by cutting off the engine during braking when the vehicle speed drops below five mph. According to Smart, the engine restarts immediately when the brake is released and the technology will result in a fuel savings of 8 percent, bringing consumption in the US EPA cycle to about 44 mpg on the highway and 36 mpg in the city. CO2 emissions will also be reduced by 9g/km, now netting 103g/km. The technology will also be available on the CDI Smart when it hits production next year, but as of right now, the diesel fortwo isn't coming Stateside.
If you've been holding your breath in anticipation of General Motors redesigning its trucks and SUVs, you're probably going to pass out so start breathing again. According to reports, it's gonna be a while. GM has announced that it's postponed any planned redesigns of its pickups and SUVs to a future date sometime beyond their previously planned 2012 redesigns. What'll it do with the extra time and money? Pouring over its entire product lineup to provide the most fuel efficient vehicles possible to a demanding public. The General announced the move in response to this drastic consumer shift away from trucks and SUVs.
GM isn't the only automaker to make product decisions based on the current vehicle market, as Toyota, Honda, Ford and others have all announced that they are shifting their lineups to include more fuel efficient vehicles. If you haven't noticed, $4-a-gallon gasoline seems to have changed the auto industry in a big way overnight. Thanks for the tip, Mike!
When we had our First Drive in BMW's new X6 Sport Activity Coupe, we didn't get the opportunity to really measure fuel consumption, since the vehicles were gassed-up when we got behind the wheel and were then refuelled during our lunch break. A glance at the on-board computer of the '35i we drove on the long route through the mountains indicated about 13.5 mpg which is nothing to write home about. The other day, BMW sent us the preliminary EPA numbers for the X6 which came in at 15/20/17mpg city/highway/combined for the turbo six cylinder model. The 404hp turbo V-8 completed the test cycles with ratings of 13/18/15mpg. When the two-mode hybrid version of the version of the X6 debuts in 2009, it will be combined only with the V-8 engine. With an expected 25 percent improvement overall, the X6 hybrid should hit about 18-19mpg combined.
