It will be in the APRIL issue of Car&Driver, not March. So we have another month or so to wait.

Replying to: paisan (Jan 24, 2008 4:54 pm) Perhaps you will not. As posted, the EPA numbers ( and testing methodology ) are substantially changed for the 2008 Model Year. Here are some details: http://www.fueleconomy.gov/feg/fe_test_schedules.shtml Of particular note in the G8 GT \ V8 context: “Beginning with 2008 models, three additional tests will be used to adjust the city and highway estimates to account for higher speeds, air conditioning use, and colder temperatures.” And: “High Speed: Represents city and highway driving at higher speeds with more aggressive acceleration and braking.” The EPA chart for “High Speed” included at the above link clearly shows speeds over 65 MPH & some “more aggressive” acceleration(s). Absolutely not a constant 65. Since ( again \ still ) we do not have any real world reports from actual drivers of production G8s, we can only speculate – and my speculation ( guess ) is based on the following, several specific numbers: Published GTO EPA numbers as they were at the time built. Published GTO EPA numbers as they would have been under 2008 MY testing. A comparison of known GTO & G8 trans. gearing \ final drive ratios & resulting RPM in highway cruising. The fact that DoD \ AFM is included on the G8. And the fact that although I do believe ( based on thousands of miles of driving a 2005 with ) GM’s DoD that the whole engine \ trans. \ final drive gearing and DoD calibration was specifically selected to maximize EPA MPG – to some detriment in the ‘real world’, for those ( like me ) who often drove at highway speeds above those included in the ‘old’ EPA test. Where the G8’s package is likely planned & implemented with the 2008 standards in mind. And highway speeds & acceleration rates more closely resembling what I often utilize, in my real world driving. I certainly hope so, at least. We shall see. - Ray Some GTO numbers: Pontiac GTO 8 cyl, 6 L, Automatic 4-spd, Premium Under 2008 standards \ tests would have been: A4 14 \ 19 14 city 19 hwy Actual stickers were: A4 16 \ 21 16 city 21 hwy The GTO had no DoD \ AFM. The GTO automatic was a 4 speed w/top ( fourth \ primary highway ) gear was 0.7:1: Overall ratio: 2.42:1 ( final drive ratio: 3.46:1 ) G8 GT V8 A6 w/top ( sixth \ primary highway ) gear is 0.67:1: Overall ratio: 1.95:1 ( final drive ratio: 2.92:1 )

Replying to: rayainsw (Jan 25, 2008 8:51 am) as it is on Chrysler's 300c as well - and it doesn't really work as 'advertised' on that car either - the car will not hold a reasonable highway speed with the DoD engaged or on any semblance of hilly terrain. 14/19 I'll believe (roughly what the 300 has been doing) it's the 24 that would require a 120 mph tailwind, or a really flat freeway that it is still possible to drive 60 on. DoD is nothing new BTW - those of us that have started to lose our hair will remember the Caddy V8-6-4s of the 80s that was a disaster and didn't last long. A 'gimmick' then - although the technology involved is certainly much more advanced - some things apparently never change. |

No NAV, no bluetooth? What is this ......a 2003 model year G-8? You'd think GM with a brand new model would want to be on the leading edge of electronic design.....not on the lagging edge of a 5 year old typical GM "has been" vehicle. NAV and blue tooth have been an available feature on drivers' cars for years and both are typically commonplace. Obviously GM mgmt is still back in the 1990s and will always be blaming unions for their woes even the problem obviously is the CEO and managers that know nothing about what America wants. I have a a 2003 DTS with NAV and night vision which was a rarity at the time, even though NAV then was common place on Euro and Lexus cars. The Caddy salespeople at the time couldn't even demo it. They still have the mindset of 75 year olds in bench seats, and so does GM as it is still in the 1990s. I had considered this car because I wish to support the USA and purchase a contemporay high performance sedan ........ yet I'd now feel as though I'm regressing if I bought it. The problem with USA manufacturing are the incompetent corporate managers that are 20 years behind the times.

Replying to: paisan (Jan 21, 2008 3:42 pm) Perhaps GM is attempting to sell On-Star, except IMHO it is not a substitute for an effective Nav system especially when you consider the cost of a yearly subscription. Besides I prefer controlling what I want when I want it and not through an external voice system such as On-Star. I currently have built in nav in a Caddy and an external Magellan that I use in my truck and wife's car. The Magellan has fewer quirks and is much less costly than the built-in. Now you can buy a Magellan, etc. nav system that is just as functional as a OEM system for only $400. Actually it is far more functional as it can be used by the driver or passenger to query the system while the car is in motion. The downside to an add-on is that they normally don't have dead reckoning which tracks location by speed and gyroscope when a GPS signal isn't available as in a tunnel or in a city with tall buildings. If the mfrs want to protect against liability yet make their NAV functional then put an interlock in that allows the passenger weight on the seat to make the system operational when in motion. I despise having to stop my Caddy to use the NAV to find the nearest hotel or rest..
