No numbers out just yet, but based on specs (3.6-liter twin-turbo V6 pumping out 455 horsepower and 445 pound-feet of torque) what are you guessing here?

 

[H13rarchy]

I would imagine similar to the stingray. 17 to 20 city and 26 to 30 highway. It will all come down to if the car is in the boost while just cruising.

 

[H13rarchy]

Just for reference the cts v sport is rated at 16 city and 24 highway. Car and Driver as noted reaching as high as 27 highway mpg.

 

[dascrow]

Anything in the high 20s on the highway would be great to see.

 

[SLO]

I wouldn't expect anything less than 28-30 for the highway being a FI, specially a turbo car..... As long as your staying out of boost mostly.

 

[H13rarchy]

Yeah but with titanium turbines I imagine this thing will be in the boost just off idle. So there should be very minimal turbo lag, if any, but not the best fuel economy. Only time will tell.

I average 19-20 around in the C7 with a manual. Freeway 27-28 as I don't use Eco but keep all 8 cylinders operating.
Is the weight of the V known yet. That will have an impact on the mileage. As long as no "gas gullzer" tax I'm OK with what ever the mileage.
My $.02 worth.

I heard it rumored to weigh 3600-3700 lbs

…any weight saving with the 6sp over th8sp?

 

[ROBERT MOZOL]

I drove a standard ATS with the V-6 as a loaner, and got 25-27 at Interstate speeds on 87 octane E10 gas. I'd take that, or even a tad lower.

 

[tedboss1]

C&D just tested the ATS-V and observed 20 mpg.
EPA city/highway is 16/24.
The weight is given as 204 lbs more than comparable M4 at 3760 lbs.

 

[al.copp]

3700 lbs. I drove my auto to 3 towns over around 60 miles cruising speed 67 mph avg 32mpg.

 

[Jay Lane]

I drove an M6 ATS-V last weekend and averaged about the same at roughly 70mph. Much better than I had expected..

 

[al.copp]

Thanks, guess most people will drive a lot faster.

[tedboss1]

For as Canadians that is equivalent to 7.3 L for 100 km which is excellent.
My CTS-V will do on the highway is 11 L for 100 km.
So the ATS-V should do at least 30% better.

32 MPG in L 100km | Car MPG, Car Fuel Consumption

 

[al.copp]

how many miles per gallon is 11L for 100km?

 

[tedboss1]

11 L per 100km = 21.38 MPG
7.3 L per 100km = 32.22 MPG

8speed lighter

 

[screameagle]

My new auto gets 19+ around town. More than I expected.

 

[Dsquared]

I average 24+ on the freeway and about 20 in the city in my 6 spd.
