The new LS7 V8 puts out 505HP and still gets 16/26 mpg

Here are some other ~500HP sports cars

Ford GT = 13/21 mpg 550HP V8

Ferrari F430 = 11/17 mpg 493HP V8

Dodge Viper = 12/20 mpg 500HP V10

Lamborghini Gallardo = 10/17 500HP V10

Acura NSX = 17/24 mpg 280HP V6 Z06 has twice the torque and better milage

The 505HP Z06 even beats out the 240HP 4 cyl. Honda S2000 in hwy mpg (26 =Z06, 25 = S2000)

 

That is just awesome....

I mean, I know fuel economy isn't exactly a priority to buyers of these cars, but damn, it's not even close!

But.... you know... that ancient pushrod technology is so old and outdated and all....

 

LOL... lets upgrade to more "high tech" OHC and get the same power with -33-50% worse fuel economy

The LS7 is the best production ~500HP engine for on the planet right now as far as I'm concerned.

 

But we already knew this considering the rest of the LSx series engines' track records on gas mileage.

 

So why does the 6 speed GTO with 105 less HP and 1.0 liter less get 25 MPG highway? Better yet, why does the same car with an AT get a lousy 21??? Simply amazing...

Great for Z06, looks awful for GTO though...

 

Couldn't a lot of it have to do with the extra-high 6th gear that's been in Vettes for some time now? I don't think you're going to get anywhere near 16 mpg when you're making all 505 of those horsies run (i.e., at full throttle or even half)...

But still. Screw those guys anyway.

 

GTO also weighs in 800+ more lbs!

to get those mpg, you probably have to idle thru each gear....

 

Best powertrains in the business=GM period. Like I always said! Wether your green, or a power junky, GM is the place to be, they are showing the world how its done, and I love it! I wonder how a paddle shifted version would do in mpg.? GTO.......yeah weights probably an issue there!

 

That's awesome.. but there is a little problem...

we know it... and GM knows it... do you think the rest of the world knows it??? NOT... so.. please.. someone at GM with power... grab the marketing team.. and tell them.. this is the message you wanna get across with the vette:

Not only does it kick ***... it is good in MPG compared to some of the vehicles it competes with.. and the Honda which supposedly are great in MPG... gets beat to the ground like a nerd getting beat by the football team.

 

It probably wouldn't be that hard getting better than 16 MPG in town if you grannied it...Any LS1 I've driven can surpass EPA City MPG numbers if you just drive sanely

 

I agree, this message needs to get out there. My sis-in-law drives a 4 cyl. (pos), and yet both my truck & Z/28, sip less fuel, while that thing sucks it up like an old BB. Getting reg. ppl to believe that fact.........Well that's a whole nother story. They've all been conditioned, starting with a certain crackpot, from yrs. ago.

 

Aerodynamics is why the GTO doesn't get as good of a highway number.

 

Just imagine if the LS7 had DoD

 

C5 Corvette Coupe has 0.29 Cd of drag.
C5 Corvette Convert has 0.31 Cd of drag.
2004 GTO Coupe has 0.31 Cd of drag.

I don't think it's aero related, at least not as much I one would think. Weight and gearing has a lot to do with mileage as well. Plus, in the case of the GTO automatic, the way the torque converter is tuned makes it pretty thirsty, or so I'm told.

 

And yes, this is the problem. Everyone I know is stunned when I tell them a V8 can get great gas mileage. They think I'm lying. When I had the 98 Corvette, a business partner thought I was lying until I filled up, we drove to Phoenix, and I filled up there--14 gallons, 420 miles, 30 MPG. We averaged about 85MPH the whole trip.

GM NEEDS to do a full advertising campaign on this. They NEED to change perception. It DESERVES to be trumpeted. And then tell them it's "proven technology, properly applied," rather than "technological acronyms for the sake of acronyms." And watch the sales go up across the board.
