I know specific details have yet to be released about the new SRT8, but based on figures for the other SRT vehicles that have been released with the new motor, does anyone think there is going to be any real improvement in fuel economy for the new Jeep SRT8? I understand its heavier than the previous model and obviously has more HP. I sold my 2008 SRT8 last year because I just got soo sick of filling up every other day it was ridiculous. I was kind of hoping that the new one might see some improvements, but since Jeep did absolutely nothing to significantly improve the WK2 hemi economy I would imagine the new SRT8 will be just as bad or maybe even worse than the previous generation SRT. I so wish it were better because I truely want a fun daily driven WK2 SRT8, but being realistic as a daily driver its a joke. I would be better off keeping my current daily driver sedan and get myself back into another 505hp C6 Z06 vette than can do 22 city and 30mpg hwy.
I know no one would buy a SRT8 or even let alone a regular Grand Cherokee for fuel economy, but unless your filthy rich I would imagine getting 8mpg on a daily driver would kind of piss you off to lol (Ok I exaggerated I used to get 12 in my 08 SRT).
So what are your thoughts on this? Worse, similar, or better MPG for the new WK2 SRT8?
I'm going to agree with rob on this. Yes its a performance SUV and can you honestly say you're going to pussy-foot a vehicle capable of the speed and hp it has? No. Yea it offers the cargo and other things a daily driver is supposed to have- bit 95% of the daily drivers also don't sport a 6.1 or whatever the new one will have. So when it comes to mpgs on this and you wanting to watch your wallet- good luck with the new one. I see guys fill up every 3 days at $55+ a fill up. Do the math, if you keep posting about the mileage and what not as a concern then I hate to sound like a broken record- but its not quite the vehicle for you. Wait till 2013 anf make a SRT clone out of a penstar model.. Otherwise you're going to have to pay to play..
It really comes down to where the gas pump "sting" kicks in for each individual. If you've got more money, then you probably have a higher threshold of pain at the pump, if you've got less money, then that threshold is likely lower. Each individual needs to figure out what the threshold is for themselves, and then decide whether or not to get the gas suckin' V8. If you decide you can take it, then buy it, and drive it like you stole it
Based on my budget, I for one don't want to pay more than $100 a week on gas. If I could pickup a new Grand Cherokee SRT8 today, based on my miles per week and expected gas mileage I would guess that I would be paying around $73 per week in gas (based on current local premium gas prices), so I've got plenty of room yet before I would consider not getting one of these beasts.
You don't even know how many miles I drive and how much of it is city vs. highway...
I'm comfortable that I could get the next generation Grand Cherokee SRT8 based on how much I drive my current moderate performance commuter. Any improvements in fuel economy is gravy for ALL of us
someone lock this thread... its going around in circles.
bottom line, bu a wk2 with a penstar and build yourself a srt8 clone- that will get you the gas mileage you want, the space you need in a daily driver and the looks of the srt. yea you might not have the performance aspect of the srt8 but hey, those interested in the performance aspect arent posting 4 different threads asking and then whining about the gas mileage of a vehicle sporting a 400hp motor.
An article I just read that seems relevant to our conversation; $5 gas by Memorial Day? How will rising gas prices play into sales figures of the next generation Grand Cherokee SRT8 (depending on the actual fuel economy of course)?
Sorry old thread but.... Jeep is telling you what the mileage is.
Standard Fuel Saver Technology and a new-for-2012 active valve exhaust system allows four-cylinder operation to engage over a wider rpm range, to deliver both improved fuel efficiency – an estimated 13-percent increase on the highway – and an extended range of approximately 450 miles on one tank of gas.
It's simple...do the math...24.6 gallon tank...450 miles per tank =18.3 mpg.
If it can achieve a 15 MPG combined official rating I might just say "screw the wait for the 8-speed" and put an order in. I'm guessing 13 city and 18 highway since the last generation SRT8 ended production with a 12 city and 16 highway official rating with no cylinder deactivation. There's NO CHANCE of a 16 city rating since the Challenger SRT8 (lighter with 2WD) can't even do that (although it would be VERY nice if I'm wrong).
Has anyone even done the math with the same car with different transmissions? One with a 5 speed transmission and the identical car with an 8 speed? I would doubt it is that significant. The fact of the matter is if you have a 6.4L engine the city numbers are not going to be that great no matter how many gears you have.
So... WHEN will we have the official fuel economy ratings on this rig? When we first see a window sticker? You'd think that the EPA would have it before then... (see www.fueleconomy.gov) I'm assuming that they have to be rated before they ship them...
