I am doing a project for my business stat class. My group is doing research on gas mileage of cars and found out that on average economy cars get better gas mileage than luxury cars. and we were wondering why this would be. I have been doing online research and haven't been able to find out why this is; I am hoping some one here could help me out.


Answer
Economy cars are usually much lighter and have smaller engines than luxury cars.

Here is a perfect example

A 2009 Lexus LS430 has a 4.6 liter V8 engine and weighs 4244lbs. It gets 16mpg city/24mpg highway.

A 2009 Toyota Avalon (which the Lexus LS430 is based off of) has a 3.5 liter V6 and weighs 3490lbs. It gets 19mpg city and 28 mpg highway.

Luxury cars are expected to be much smoother and quieter than some cheaper cars. To do that, the additional sound deadning materials and techniques require the car be heavier. Luxury cars are also expected to be a little faster than economy cars therefore a larger more powerful motor is needed.

What luxury cars get great gas mileage?

Looking for 2010, 2011 or 2012 luxury car for around 30,000 with close to 40 mpg. My wife and I don't want to settle for a Prius or Civic, but we do want good MPG because we drive so much. Is this possible without spending too much more?


Answer
If you take a closer look at the Prius, you'll see that you aren't "settling". It has many of features only found in luxury cars. It's a mid-sized car, not a compact like the Civic, so room is not a problem.

Note that decent luxury cars start at about $45,000.

My 2004 Prius has cost 12 cents per mile for dealer maintenance, tires, and fuel combined over the 120,000 trouble-free miles I've driven it so far.

My 2004 Prius MPG from the logbook. (Complete years only):
2003-2004 -- 50.8 mpg 17,628 miles
2005 -- 52.6 mpg 14,688 miles
2006 -- 56.3 mpg 16174 miles
2007 -- 57.3 mpg 18384 miles
2008 -- 59.9 mpg 21755 miles
2009 -- 61.4 mpg 16177 miles
2010 -- 65.2 mpg 12134 miles
