Corvette Stingray EPA Fuel Economy released -- 17 / 29 MPG

[dwightlooi]

The Corvette Stingray's fuel economy numbers as measure by the official EPA test cycles are...

Corvette Stingray -- 6.2L Pushrod OHV V8 -- 17 (City) / 29 (Highway) MPG*

* 17/28 mpg w/o Cylinder Deactivation; 17/30 mpg in Eco Mode (Enables Cylinder Deactivation)

Compared to the outgoing (C6) model, the 7th Generation Corvette is 1 mpg (city) / 2 mpg (Highway) better in fuel economy without relying on cylinder deactivation. With AFM enabled, this climbs to 1 mpg (city) / 4 mpg (Highway). This is in fact better than an 2009 Acura TL Type-S (17 / 26 mpg) makes the Corvette the most fuel efficient car in its performance category -- certainly the most fuel efficient vehicle with 460 hp / 465 lb-ft and which hits 60 mph in 3.8 secs. For comparison, the fuel economy numbers of some similarly high performing vehicles are as follows:-

Ferrari F458 Italia -- 4.5L DOHC V8 NA -- 12 (City) / 18 (Hwy) MPG

Porsche 911 Turbo -- 3.8L DOHC H-6 Bi-turbo -- 16 (City) / 24 (Hwy) MPG

Nissan GTR -- 3.8L DOHC Bi-turbo V6 -- 16 (City) / 23 (Hwy) MPG

Audi R8 -- 5.2L DOHC V10 NA -- 13 (City) / 19 (Hwy) MPG

Ford Mustang GT500 -- 5.8L DOHC V8 Supercharged -- 15 (City) / 24 (Hwy) MPG

Lexus IS-F -- 5.0 DOHC V8 NA -- 16 (City) / 23 (Hwy) MPG

Lotus Evora -- 3.5L DOHC V6 NA -- 18 (city) / 26 (Hwy) MPG

Oh, so you're saying they went with DOHC on the new Corvette then? Because no ancient pushrod set-up could be that stingy on gas.

With this we can make a reasonable projection as the the Fuel Economy numbers of an ATS-V if powered by the LT1.

Corvette C6 -----------------------> Camaro SS

3250 lbs ----------------------------> 3850 lbs

Cd 0.34 -----------------------------> Cd 0.35

6.2L LS3 V8 -----------------------> 6.2L LS3 V8

16 (City) / 26 (Hwy) MPG ------> 16 (City) / 24 (Hwy) MPG

Corvette Stingray (C7) --------> ATS-V (Hypothetical)

3200 lbs ----------------------------> 3700 lbs (est)

Cd 0.29 -----------------------------> Cd 0.299

6.2L LT1 V8 (w/ AFM) ----------> 6.2L LT1 V8 (w/ AFM)

17 (City) / 30 (Hwy) MPG -----> 17 (City) / 28 (Hwy) MPG

That's pretty darn good compared even to the naturally aspirated 3.6 DOHC V6 (19 / 28 mpg).
