Hybrid Car Review

When it comes to hybrid cars, most people think of fuel efficiency.  How many miles per gallon can you get if you're driving a hybrid car?  What kind of improvement can you expect if you buy a hybrid over a gas-only car?

The answer is, of course, it depends.  Not all hybrid types are born equal and not all fuel efficient cars are hybrids.

As a side note, the new Ford Fusion Hybrid and Mercury Milan Hybrid are going to be right up there (41/36 mpg) when they arrive over the next few weeks.  So will the new Honda Insight (40/43 mpg).  The new Prius will set the bar a little bit higher at over 50 mpg.


Miles Per Gallon v Gallons Per Mile
Note that miles per gallon can be pretty misleading.  If I told you could go from 35 to 50 mpg or from 15 to 20 miles per gallon, which would you say is a bigger improvement?  Turns out going from 15 to 20 saves you 200 gallons a year if you drive 12,000 miles.  Going from 35 to 50 only nets 100 gallons a year.


Now, there's no doubt that, given the choice, you would rather get 50 mpg.  The problem I'm talking about is the scaling.  That's whay in Europe, they talk about how many liters per 100 km.  If we could switch to gallons per 100 miles (GPM), we'd be better off.

That's not likely to happen any time soon, but it would be nice.

If you glance at the miles per gallon to gallons per 100 miles chart above, you'll see what I'm talking about.  Going from 15 mpg (6.66 GPM) to 20 mpg (5 GPM) gives you 1.66 GPM difference.  But going from 35 mpg (2.86 GPM) to 50 mpg (2 GPM) gives you only .86 GPM difference.  Clearly, going from 15 to 20 mpg gives you more improvement than 35 to 50 mpg.

Which is why the hybrid SUVs from GM are better than they seem.
