The website offers fuel costs and MSRP of 18 2012-2013 vehicles

The U.S. government just introduced a new section to its FuelEconomy.gov website that allows consumers to compare the payback of certain hybrids and their traditional gasoline counterpart.

The website offers fuel costs and MSRP of 18 2012-2013 vehicles. Consumers simply choose a hybrid model and move the sliders appropriately to see the payback period and fuel savings for that particular vehicle. The calculations are based on fuel prices, city-highway driving percentage and annual miles.

"Based on MSRP and fuel costs alone, hybrid vehicles can save you money versus a comparably equipped conventional vehicle," said fueleconomy.gov.

Some of the vehicles available on fueleconomy.gov are the 2012 Ford Fusion Hybrid, 2012 Toyota Prius C One, and 2013 Chevrolet Malibu Eco.

An example of the information that the website offers is a comparison of the 2012 Hyundai Sonata Hybrid and the gasoline-powered 2012 Hyundai Sonata SE. According to fueleconomy.gov, the hybrid Sonata costs $2,655 more than the conventional version and takes about 5.1 years to pay back.

The government is certainly looking to push consumers toward more fuel efficient vehicles, especially with the White House's recent proposed 54.5 MPG CAFE requirement for 2017-2025 model year vehicles. This standard would save customers $6,600 at the gas pump for the lifetime of a 2025 vehicle.

I think diesel technology in general is more reliable than gas, but I was particularly concerned about DI diesel. How much repair/maintenance did you have to do on those 300k miles?

Re: Your question about reliability of DI diesels, there are a variety of different implementations. Direct Injection itself a concept, not a specific technology. The early DI diesels (1990's) used a belt (or chain) driven rotary pump, just like the old indirect diesels. Reliability was excellent, same as the indirect diesels.

After that came some interesting different implementations, like VW's "pumpe deuce" unit-injectors where an individual injection pump was incorporated into each fuel injector. That had its quirks, like requiring a very specific type of engine oil and no other.

Now that we're into "3rd generation" direct inject diesels, all the automakers seem to have converged on Common Rail direct injection. Common Rail allows for the highest injection pressures (31,000 psi in the latest models) and is inexpensive to build.

BTW the higher the injection pressure, the better. Higher pressure allows for tighter control of ignition timing, fuel atomization, emissions, etc.
