#99 of 103 Mileage DOES vary by bricklacrosse
Nov 28, 2012 (3:12 pm)
Have a NEW 2012 Lacrosse 4cy with e-assist. I have been averging 25 mpg in mixed driving. No issue here. My HUGE issue is with highway mileage. 26-27 mpg with cruise set and no AC. What gives Buick??? Horribly overstated highway mileage. I just got rid of 2005 Prius with 300K on the odometer (which I still averaged 40+mpg the day I junked it)for this American car hoping to get 30mpg...Could have bought a Benz or Audi and got the same mileage.#100 of 103 Re: Mileage DOES vary [bricklacrosse] by crankeee

Sounds like 25 average is on the number so city MPG is ok or better. The highway # is off but probably within the "acceptable range". Our 2010 CXL with3.0L V-6 gets 28-29 at speed limit of 65 - 75. Drops off at more speed. City MPG is predictably low at 16-20 depending upon conditions. Moving that 4000# car from a stop requires energy. Hybrids do very well on city MPG, but approach or slightly exceed on highway, so did not work for us with mostly trip miles. Each car is set up for maximum city or highway. New Camry hybrid seems to reach best balance if you feel the need.

Good morning bricklacrosse, Congratulations on your new LaCrosse!
Generally, a new vehicle will not achieve it's optimal fuel economy until the engine has broken (this will take 3 to 5 thousand miles). A gradual increase in fuel economy can be expected - please keep us posted on this, though! We're here to answer any questions about the product you may have, assist in the process of working with a dealership, or look into any warranty or recall questions.
Sarah, GM Customer Service

This is true. My 12 LaCrosse's first few tanks were really low. It got much better by 1000 miles and leveled off around 3K or so. My overall MPG with an 70city/30hwy mix is hovering around 18.3. Not too bad for a 4200lb car with over 300HP. My wife and I don't baby it either.
