This tip was originally sent out in 2007.
We just received the first glimpse of how the new EPA testing methods are going to affect the mileage estimates for our cars.
As we discussed in an earlier tip, the EPA mileage estimates are a great way to compare one car to another. But, as most people notice, they seem a bit removed from the way most of us drive. So the EPA has been adjusting the testing procedure to help make the EPA numbers more realistic.
We now have the results from one of the first cars to be tested with the new method. We actually are about to receive the first of the 2008 Lexus RX350s. (We've almost sold out of the 2007s that were produced, so here we are, already making a model year change. Pretty wild!) For reference, the 2007 RX350 had EPA ratings of 19 city and 24 highway for the All Wheel Drive model. The new 2008 has ratings that are 2 mpg less, or 17 city and 22 highway. There are corresponding changes for the two wheel drive model also.
Keep in mind, nothing has changed with the engine or transmission. The only thing that has changed is the way it's tested. Now the tests take into account a few more real world factors such as
So what does this mean for you? As we move forward, the EPA number will not only be a great way to compare cars to each other, but they will be a better way of approximating what you might expect from a car. Of course, no test can accurately reproduce your specific driving style, vehicle and road conditions. So we'll probably always see that classic disclaimer, "Your mileage may vary."
Best wishes for safe driving!
