gas mileage on 2009 CTS v at 60mph with 3 inch exhaust and 2.55 pulley.

[Adic2Speed]

I have an 09 CTS-V, I don't think my MPG indicator is capable of going over 20, unless I'm going down hill, or being towed.

wow man its so smooth inside

[victoriadish]

Is that a boost gauge on the right at the bottom?

[baur02]

@victoriadish pretty sure it is. the V comes with a supercharged 6.2L V8

[smbstressfest]

Were you expecting an MPG hit from swapping out exhaust?

[MrChubs1]

LOST much? ?? If anyhing it should pick up MPG from the improved efficiency.

[andymarty80]

Nice, what about the gas mileage in the city?

[advancedwarfighter07]

my 2005 3.6L CTS gets the exact same milage as this 6.2L Beast. It just shows the breakthrough in car technology. Im told with the right performance mods, the 09 cts-v is capable of 31mpg at 60mph

@advancedwarfighter07 any car can get 30 mpg if driven properly, but not driven properly, any car can also get horrible mpg.

example: my 2004 mazda 6 gets 17 mpg because i floor it whenever i can.

@coolerdude44 Any car can get 30 mpg? That's complete BS.

@advancedwarfighter07 While I love the CTS-V, a pushrod V8 with a blower is not exactly breakthrough technology.

Fuel efficiency at a steady 60mph comes down to gearing, aerodynamics, and rolling resistance.

ill be putting on some drag strip footage this weekend. :)

@wait4meperformance The MPG's are impressive but we all know the CTSV is about slapping around AMG's and M's.
