Comparison Test: 2008 Dodge Charger R/T vs. 2008 Pontiac G8 GT - You know, big, fast American cars. They're not hybrids, they don't run on biodiesel and they rumble and roar through dual exhausts. And they do the sort of epic burnouts that inspire Bruce Springsteen songs. (more)

Cars like the new 2008 Pontiac G8 GT and 2008 Dodge Charger R/T were once supposed to be every American's birthright. Brawny, V8-powered, relatively affordable rear-drive cruisers that can blow through a couple of big Western states in an afternoon at 90 mph — their drivers staring at the horizon through Ray-Bans, steering with one hand and smoking a Pall Mall with the other.

Before I dive in to my topic: watch the Sunfire cracks. I had a Sunfire ('96 I think, the first year it came out), and until it was totalled in a head on collision, it was a terrific car. It had great low end grunt (at least my 2.4 liter version) and was a great city car. It got pretty good mileage and gave a lot of bang for the buck. I compared it to the Civic at the time. I got ABS, traction control, alloy wheels and a boat load more power for a couple grand less than the Civic. Anyway. based on what I saw at the Chicago Auto show, the G8 should eat the Charger's lunch. I like the Charger and think it a great looking car, a little better looking than the G8, but the G8 should price out a couple grand cheeper than a comparable Charger and the interior space is FAR superior. I'm 6-4 and in the back seat of a Charger my head hits the rear window. In the G8, with the driver's seat adjusted to fit me, I could sit in the back seat and my knees didn't touch the seatback and I there wasn't a risk of concussion if the driver hit a bump.
#3 of 48 why so quick?? vs Charger R/T by rayainsw Feb 25, 2008 (11:26 am)
Why is the G8 GT posting ‘such good quarter mile times’? I believe that part of the answer here is the gearing. The Edmunds test refers to the 2.92:1 final drive ratio. Not considered very ‘aggressive’, normally. In this particular case, paired with the 6L80’s first gear ratio of 4.03:1, it actually is fairly aggressive. [[ For reference, the 2006 – 2008 Corvettes with versions of the motor and this automatic trans. have standard final drive ratios of 2.56:1. And now, for 2008, an optional ‘performance’ axle ratio – of 2.73:1. ]] The Charger R/T’s first gear ratio is 3.58:1 and the final drive ratio is 2.82:1. [[ This means the G8 GT ‘launches’ with around 10% greater mechanical advantage. Assuming that the tire diameters are approx. 7% different ( the Charger’s tires, in the Edmunds test are 225/60x18s vs 245/40x19s on the G8 GT w/Sport Pkg - means the Charger has roughly 7% higher RPM ) and assuming similar initial Torque Converter behavior in the 2 automatic transmissions. ]] AND ( I think particularly relevant here ) Pontiac chose a final drive ratio that allows the G8 GT to hit the Quarter Mile lights at the very top of Third Gear. Third gear redline ( 6,000 RPM ) is 104 MPH. And the Quarter Mile Terminal Velocity in each test I have seen so far is between 102.8 and 104.1 MPH. So: The motor is at peak HP and no 3 – 4 shift is required before the end of the Quarter. The Charger ( non-SRT8 ) in tests I have see is geared for 118 MPG in Third gear – and clears the Quarter running at roughly 97 to 101. Just my 0.02 gallons worth . . . - Ray Pleased to see these acceleration times . . . Replies to this message: budoinst (Feb 29, 2008 12:31 pm) xtec (Mar 01, 2008 10:06 am)

Replying to: rayainsw (Feb 25, 2008 10:59 pm) It doesnt take much to figure out that I car that weighs less,has more power is going to be faster.So whats the point?I still like the looks of the Charger better then the G8.Gas keeps going up,so I dont think the sales will be that great.

Replying to: rayainsw (Feb 25, 2008 11:26 am) While reading the article, I got a chuckle. I love it when they say that the G8 is as fast or nearly as fast as the SRT8, which I own. On it's worst day and not with trying will it turn a 5.4. On many runs she averages 4.8-4.9, which is well below the number they show. By the way, I believe the G8 is a great vehicle and it should do well. Replies to this message: xtec (Mar 01, 2008 10:06 am)

Replying to: budoinst (Feb 29, 2008 12:31 pm) I did the same thing you did.The SRT Challeger does the 0-60 in 4.7sec.and the 1/4 in .13.1 This is in the new Car and Driver Mag.The Challenger is no light weight coming in at 4150.They are trying to make the G8 look good seeing that the GTO was a failure.
#8 of 48 sales # under which RT or SRT8/challenger would be a failure?! by elias Mar 02, 2008 (7:24 am)
what's the sales # per year under which the SRT8 or challenger or charger-RT would be considered a failure like you consider GTO, xtec & budo ? how is SRT8 doing for sales/inventory so far - maybe that will somewhat indicate how well challenger & charger-RT will do sales-wise? aren't G8 sales capped by the slow-boats from down under? in a sales-comparo, would we pick the same # for G8 & charger-RT as being an indication of sales success/failure?

Replying to: elias (Mar 02, 2008 7:24 am) Put it this way The Charger is still around and the GTO is gone.Why because they couldn't sell the GTO.

Replying to: xtec (Mar 02, 2008 10:02 am) I was sitting out front of work the other day having a break. There was this car parked out front, fugliest looking thing I have ever seen. Didn't know what it was until I saw that video of the Dud Chunder vs G8. Looks like one person designed the front and another did the back. They didn't quite meet up in the middle. Was it designed in India?
