More natural gas. Less diesel. That's a quick synopsis of a study by Navigant Research on future fueling trends for trucks.
Liquefied Petroleum Gas
The possibility of $1-a-gallon fuel would make a lot of US governmental entities sit up and take notice. The state of Oklahoma and the city of Dallas are making that happen. Those two entities are buying up a bunch of Ford F-150 pickups retrofitted to run on compressed natural gas (CNG), all in the name of cost savings and emissions reduction.
Between 2000 and 2009, the United Parcel Service (UPS) increased the fuel efficiency across its fleet of 60,000 delivery vehicles by a relatively remarkable ten percent (with more on the way). Part of that boost is attributed to UPS' extensive deployment of alternative fuel vehicles, like the 48 Kenworth-built, liquefied natural gas- (LNG-) fueled heavy-duty trucks that the delivery company will soon add to its fleet.
Maruti Suzuki, one of India's leading automakers, has launched a website dedicated to its upcoming Wagon R Duo, a dual fuel model that burns either gasoline or liquefied petroleum gas (LPG). Maruti's site highlights the model's factory-fitted LPG tank and its unique dual ECU setup, which allows the vehicle to seamlessly switch, by pressing a dashboard-mounted button, between gasoline and LPG.
Last fall, General Motors announced that commercial fleet customers could order the full-size GMC Savana and Chevrolet Express vans outfitted with either compressed natural gas (CNG) or liquefied petroleum gas (LPG) fuel systems. Now, GM has expanded its LPG option to include the 2012 Chevrolet Express and GMC Savana cutaway 3500 and 4500 vans.
One one hand, we have the HUMMER H2, which is pretty much the least green vehicle on the road; indeed, if the Prius is the standard bearer by which others are judged, the H2 is the pallbearer. On the other hand, we have liquefied petroleum gas. LPG, as it's more commonly referred, burns much cleaner than gasoline and just about any internal combustion engine can be converted to run on the fuel. What happens when you combine the two?
Holden's dual-fuel V6 is being offered in the new VE-series Omega, Berlina and select Commodores. The 3.6L Alloytec powerplant can switch seamlessly between LPG (Liquefied Petroleum Gas) and gasoline without any serious difference in power. Furthermore, the setup is said to offer an operating range of 1100km (683 miles) or better (assuming both tanks are full at the beginning of a journey).
