Granted, the X is a few hundred pounds heavier than the Coupe, but you have to really be on it consistently to get as low as 12. Glad you are enjoying the car! And don't you just hate to see those gas prices relative to last August? Yahoo!  Jack |

Replying to: sweendogy (Jan 24, 2009 1:15 pm)  1800miles I'm averaging 16.2 with about 50% highway driving. My V6 6 speed Honda coupe was about 3 tenths of a second slower to 60 but averaged 20 mpg even when I flogged the crap out of it. This thing is no where near the published EPA numbers and I thoiugh hesitation was worked out in all cars years ago.

Replying to: rhard49 (Jan 25, 2009 1:01 pm) That .3 of a second Infinity advantage to 60 mph (one mentioned) compared to the Accord works out to 26.4 feet or nearly 9 yards! If you wanted economy, why didn't you stick with the Accord or better yet get a Civic? The Accord will not out handle the Infinity. Nor will it outbrake it. Here is what folks have contributed. New car, tight. Frigid outdoor temperatures. Idling to warm up the car. City driving. Speed.....i.e., 75mph. Winter blend gas. What the car is and enjoying it. There are a few web sites out there that actually have confirmed through testing that the best fuel mileage for most passenger cars is achieved between 45mph and 55mph. After that, as the speed increases linearly, the fuel mileage falls exponentially. Wind resistance. Didn't you ever wonder why a 330hp G can hit 155mph WITH the speed limiter; yet a 500+hp Z06 Corvette with better aerodynamics can't go just 45mph more top end and hit 200mph? That is how severe wind resistance negatively affects a car. You can figure in fuel economy why you are at it. At Christmas I rented a 2007 gasoline powered Chevy Tahoe, stuffed 5 people and luggage inside, and hit the cruise at 70 mph, got 20mpg out and back, 2,084 miles. Despite the gas formulation, winter temperatures, weather slow downs, and 7 potty/food stops for those with weak bladders. A stinking 6,000 gross vehicular weight Tahoe, weighed before passengers and luggage. The folks that ARE getting the G's epa mileage figures didn't luck out and get an extraordinary car. Look in the mirror, read up on how to max your fuel economy, or simply pay attention to your right foot. Anyone can get the low mileage figures too, but we/they can also meet the city and highway epa numbers as well. I have issued this suggestion before and NO One has responded. Go out on the highway. With the engine at operating temperature. When you reach the speed limit (55-65mph, whatever), hit cruise and reset the fuel mileage readout. Drive 100 miles of pure highway, unimpeded by traffic, tolls, and the related speeding up and slowing down. THEN report back your mileage to us. Even in the dead cold of Winter and with the Winter gas formulation, a broken in G can get you 24 highway and 16-17 city. Eliminate the temperature lows and the reformulated Winter gas and you will probably achieve the epa highway figure with a broken in G. Stop worrying about the fuel economy, or simply enjoy the car. |

Replying to: pscheid (Jan 22, 2009 12:08 pm) I guess my foot is a little heavy  ...but how fast can I drive on Sunrise Highway (L.I. New York). I'm driving to New England this weekend, so I will zero out the odometer and set the car on cruise control. I'll let you know the results. Thanks

Replying to: trinbago1 (Jan 26, 2009 8:40 am) Trinbago-- i suggest if your making the trip up north--to do one thing-- take the merrit parkway (the navi will tell you to take 95n-dont listen to it) all the way up until you hit I 91 in CT-- the reason you should take this highway is to truly enjoy the G-- lots of turns at highway speeds -- you'll also get some sweet straightaways and there is always someone willing to match you on speed bursts. Once on 91 then hit cruise and you'll see the MPGS climb-- best of both worlds -- I filled up tonight-- 13.4 mpg for the tank --17.3 gallons to be exact before the stupid "warning light" went on. 20-17.3= 2.7 gallons left. All city driving as you probably guessed.

Replying to: sweendogy (Jan 26, 2009 5:22 pm)  The advice given by pscheid was on the money. Based on my calculations, I averaged 22-23 MPG. Keep in mind at times I was doing 75MPH. The car is really great. when I arrived at my destination, I did not feel like getting out of the vehicle. Now i have to be concerned about speeding tickets. LOL. |

Worst mileage rating I got was 14.5 MPG of pure local driving (NYC burbs) Best non-winter fuel mileage was 24.4 MPG going from NJ to ME (pure highway) with the stock A/S Dunlops Best winter fuel mileage was 23.4 MPG going from NJ to NH (pure highway) with the winter Dunlops Highway speed probably averages about 72 MPH. Too many speed traps in CT, so I have to watch it. It is tough to drive this car slow, but it is tougher paying speeding tickets and higher insurance rates. Averaging about 21.5 MPG with 70/30 Highway/Surburban driving I'm satisfied with these numbers that I am getting.
