Naysayers alert: cost of diesel drops below premium gas
At least one barrier to diesel ownership may be falling by the wayside now that the average price for a gallon of diesel fuel has dropped below that of premium gasoline in the United States. According to the Energy Information Administration of the U.S. government, the average price of diesel fuel in this country on February 16th was $2.18. By way of comparison, the average gallon of premium gas: $2.19. Of course, even that isn’t an apples-to-apples comparison because a gallon of diesel fuel contains more potential energy than a gallon of gasoline. Add in the fact that internal combustion engines running on diesel fuel are more efficient than their gas-powered counterparts, and diesel starts making even more sense. Still, it’s not all rosy for diesel engines in America. There are many ways to measure emissions, and in some cases, diesels aren’t so clean. Specifically, oil-burners exhaust higher levels of nitrogen oxides and sulfur oxides along with particulate matter (soot) in the form of unburned carbon compounds. All of these issues can be mitigated somewhat, but that costs money. Still, diesel (including biodiesel) is an alternative that is looking more and more practical as time marches on.

Click above and scroll down to watch the video While perhaps not as spectacular as San Francisco getting a fancy Smartlet charging station in front of City Hall , the addition of two charging posts at Truckee Meadows Community College in Northern Nevada are a welcome addition to the nations slowly-growing charging infrastructure. The posts, which use a traditional parking meter interface and ask for only 10 cents an hour, are getting put to good use, as we learned from a bit of video by the local NBC affiliate, KRNV. As interesting as the posts were, the station found one of the vehicles regularly using them was just as interesting: a 1991 GMC Van. Around the time GM was refining the Impact prototype that would go on to become the EV1 , some GMC vans were built with an electric drivetrain for the Department of Defense, according to the vehicle’s owner (Southern California Edison got some too). Able to go 70 miles on a charge, the vehicle requires little maintenance and its driver seems very happy with his old EV ride. If you are thinking that you’d like a van like this yourself, you may be in luck. A nice looking 1989 copy is listed on the EV Album by someone who says, “I’m considering selling this, contact me with offer.” If that doesn’t pan out and you’re good with a wrench, there’s another in need of extreme TLC on eBay for the next few days. Video after the jump.

Click the Cayenne hybrid for a high res gallery Porsche has just released more information on the new Cayenne S Hybrid that will finally launch in 2010. The company has changed up its powertrain plans since originally announcing the hybrid. Instead of the older 3.6L normally aspirated V6, it will now use the new supercharged and direct injected 3.0L found in the new Audi S4 and A6. The 333 hp V6 is paired up with a 52 hp electric motor sandwiched between the engine and 8-speed automatic transmission. The combination of the engine, motor and nickel metal hydride battery can propel the Cayenne to 62 mph in 6.8 seconds. The 154 lb battery pack occupies the spare tire well. As a strong hybrid system, the Cayenne can operate in electric, internal combustion or blended modes. The motor and battery have enough power output to allow the SUV to run on electricity at speeds up to 82 mph when cruising on level ground. The hybrid motor also replaces the conventional alternator further reducing parasitic losses in the system. Porsche expects the hybrid Cayenne to top 26 mpg (U.S.) on the NEDC combined drive cycle, slightly better than the 25.3 achieved by the new diesel.
