XTerraVersa has it right.
THE EPA does the mileage testing, not Nissan. The EPA certifies the testing. Nissan puts the sticker on that contains the EPA results. If you want to be mad at someone, be mad at the EPA, not Nissan.
Here's why you'll never get the high end mileage from your Versa that the EPA gets:
Quote »The city and highway tests are currently performed under mild climate conditions (75 degrees F) and use acceleration rates and driving speeds that EPA believes are generally lower than those experienced by drivers in the real world. Neither test is run with the use of accessories, such as air conditioning. The highway test has a top speed of 60 miles per hour, and an average speed of only 48 miles per hour.[/quote]Any of you out there go no faster than 60 mph? Anyone out there average 48 mph on the freeway?
Here's another doozy:
Quote »Since the mid-1990s, EPA's emission certification compliance regulations have required the use of three additional tests which capture a much broader range of real-world driving conditions; specifically: high-speed, fast-acceleration driving and the use of air conditioning and colder temperature operation (20 degrees F). Not only do these conditions impact the amount of air pollutants a vehicle emits, they also have a significant impact on a vehicle’s fuel economy. However, they are not currently required to be used to measure fuel economy.[/quote]Go here for more info:
