An IntelliChoice.com survey finds that most 2009 US hybrid and clean diesel cars, trucks and SUVs deliver a lower total cost of ownership compared to gasoline versions of the same (or comparable) vehicles. The point we make is that it is not just about fuel. Buyers also need to consider costs such as maintenance and resale value.
A123’s Engine Start Battery is designed as a replacement for absorbent glass mat (AGM) and other lead acid batteries, providing a lighter-weight, longer-lasting solution for micro-hybrid functionality that enhances vehicle performance, improves fueleconomy and lowers total cost of ownership. Reduced Weight.
Do they receive HOV access for their improved fueleconomy and ultra low emissions? In fact in 6 of the states, diesel fuel is penalized with additional state taxes. So diesel fuel gets taxed twice or penalized twice at the federal and state level. This helps us to make better fueleconomy and good emissions.
They also found that the total costs of ownership (TCO) of the electric and diesel trucks are similar. The first upstream component accounts for indirect energy input for the production and distribution of power generation fuel and the construction, maintenance, decommissioning, and waste disposal of the power plant.
The longer life and increased fueleconomy yield a benefit to the EXT Li-ion batteries, according to A123’s calculations. EXT addresses cold cranking, and in addition, can reduce total cost of ownership (TCO) for micro-hybrid applications. start-stop) and telecommunications, especially in developing countries. Jeff Kessen.
Green reviewed the role clean diesel vehicles play in the current vehicle fleet by analyzing the total cost of ownership of diesels and comparing it to that of their gas vehicle counterparts. They developed three- and five-year cost estimates of depreciation by modeling used-vehicle auction data and fuelcosts by modeling government data.
Diesel powertrains can achieve fueleconomy gains of up to 35% when compared to some gasoline powertrains. Further savings would be gained from diesel’s lower maintenance requirements, longer service life, and overall lower cost of ownership.

Why Clean and Functional Injectors Are Crucial Think of fuel injectors like the arteries of your engine. Heres what can go wrong when theyre not in good shape: Poor fueleconomy – Dirty injectors can spray too much fuel or spray it inefficiently, which means your engine has to work harder and burn more fuel.
Low cost of ownership was of paramount importance to the design team, and the new engine boasts excellent longevity and ease of service. The new engine is also designed for straightforward long term maintenance, for example with the inclusion of wet cylinder liners for simple replacement.
General project targets were to deliver diesel-like or better fueleconomy using E10 gasoline (RON91), and to achieve low engine-out NO x and PM using low temperature combustion, the intention being to avoid the cost of aftertreatment for NO x and PM, in addition to meeting more stringent standards. DOE UFEV program targets.
