I thought 400 (I beleive thats at the wheels) in the Jag was just about perfect. I can average about 19 or 20 mpg and get 25 doing 75-80 on the highway. And it moves really well.
At first I thought the V's 560 is just way too much but now I understand that's before losses. I read here that it's more like 470 at the wheels which isn't as far off what I am used to as I originally thought.
So I'd like to know if I have understood the HP numbers right for the two cars and what sort of mpg penalty do you figure the V's extra HP is going to take?
I've always liked cars that had more to give than the normal road horsepower and typical slushy repsonse to the pedal. I'm trying to get a better handle on this new little monster from Cadillac.
Thanks for any help. |
That Jag's engine produces 400 HP at the crank, not at the rear wheels, so the 556hp V2 has significantly more power. I stepped up from a 400hp GTO (modded to around 430) and the difference is night and day. Power on demand at all RPMs and gears.
I've had my V for a few weeks and am averaging around 13mpg currently. I would take that with a grain of salt as I've not really been driving it "normally" yet. I'll know in the next month or so what mileage I can expect.
I'm also keeping an eye on those in the forums who've had the PCM tuned. I'm anxious to determine if the MPG increases that've been reported are real and to see if there are any other issues with the tunes.
