    Road trip MPG - not bad

    140 miles rolling hills 75 deg

    21.8 mpg @ 83.5 ave mph with 91 oct no cruse control and jumping the hills slightly

    Way back

    20.9 @ 75mph on 93 oct 10% eth

    That's really on par with my SRT8. So I'm pretty happy.

    Re: Road trip MPG - not bad

    That's about 2 mpg better than I ever got and with a 18 gallon tank I was forever putting gas in the car and having to answer questions about the car whenever I stopped which got really tiring. At least with the Benz it holds 21 and I regularly get 23 mpg, variable valve timing, 7 speed auto and more efficient twin turbos over a supercharger make a difference. I put gas in the car every 350 miles vs every 200 with my 2013 Vagon. People very rarely ask about the car as it flies under the radar screen a lot more, only people that know what a AMG is and how rare the Wagon is get excited about the car.

    You must really miss your Cadillac, the way you continuously try to convince us how great your non-Cadillac is. It's okay, we get it, and we thank you for taking one for the team and confirming how lonely and soulless the Mercedes life is.

    That's better than what I got on my road trip. I wish I could hit 20 mpg consistently, at over 80 mph. Something must be wrong with my right foot.

    ROFL I was going to post this almost word for word...

    Nothing to add, move along.

    ----------

    The MPG is 1.5mpg better by not using 10% Eth. In addition, The sweet spot appears to be around 80mpg, and I was happy with the mpg at an average slightly above this. I've never checked this at 60mpg, who drives that slow!?

    This is one great thing about the corvette, it will get 26-30mpg at these kind of speeds all day, where many times, with performance cars that supposedly get 24-25mpg, the efficiency can really drop off after 70-75mph. This was the case with my SRT8 392. The only way to get the average mpg of 24 was to stay right around 72-74. Anything above that, and I'd lose a good 1-2 mpg every time.

    *sheepishly raises hand*

    I've done that in the past and got almost 23 mpg. Normally on freeway runs I'll do 65-70 mph and get closer to 22 mpg. The speed limit on our freeways is an artificially low 100 km/h (~60 mph) but that's another thread for another day.

    ^^^Canada...yes.... no cars open road 3 lanes 45MPH...

    We still have some highways here in the States at 55mph, I just do not typically travel on them - I would guess the milage would improve slightly as you say.

    Re: Road trip MPG - not bad

    At 75-80 mph and 250 mile trip on interstates in TX, I consistently get ~21 mpg with cruise control on. At lower speeds 65-70, I'm getting almost 22 mpg. Car currently has about 17k miles.

    I just did a Peoples Republik to Florida trip ~900 miles each way. 20.5 going south, 19.7 going north. The difference was speed. 72 vs. 78

    of course lower mileage going north; as shown on a map, it's all uphill

    Re: Road trip MPG - not bad

    Its almost an oxymoron when you're discussing 550+hp cars and talking mpg's. My current daily driver is a Chevy Tahoe so it's good news that I will be getting about the same or more mpg's driving the V.

    Are these mpg averages mostly for manuals or both?

    Do not expect this type of MPG.
    I get 12 mpg and I drive mostly suburbs, and this is taking it easy on the throttle.
    With spirited driving, I'll get <10 mpg.

    Wow. I'm an idiot in this car and I get 14. I have suburb and highway mix though. 20+ on highway trips. And my car has about 600 at the wheels.
