silent cylinder deactivation? by mrpushrod

Yes, you can feel it. I own a G8 GT and drove two other G8s. It gives you a slight vibration when it is in 4 cyl mode.It does this when you are cruising along with a light foot on the gas pedal. The more you keep it in this mode the higher the MPG. You can disable it by shifting into sport mode. I achieved 26MPG on a trip by keeping light foot on the accelerator. The G8 does very well on highway gas mileage. All around we get around 20MPG. What's funny is we traded a Lincoln Town Car for the G8 that had dual exhaust and a low rear end ratio (Cartier addition and limo's have this setup) and it achieved an excellent 22MPG all around yet highway mileage was ~ 23.5 MPG (less than the G8. The G8 engine is very quiet and smooth other than when it is in this mode. There is no jerk or when you go in and out of this mode and power delivery is always consistent and there when you need it. And as expected with an engine this size, torque is unbeatable. Anyone driving a vehicle with a 4 Cyl or V6 will appreciate the torque.

These Holden cars are *fantastic*, as are the Chevy V8 engines.
Testdrive and see for yourself.

I have a feeling though that once the car is truly "broken in" the switching to 4cyl mode will be less felt. Also, I would imagine once that happens, you will see a slight increase in mileage. So really it can only get better. I truly believe a car takes awhile to be broken in, as I now have a 4cyl G6, and ever since I have returned from a 2,400 mile trip, I kid you not, it actually feels much better!! It has more torque in the bottom end, the transmission shifts better. The engines seems more calm now, I only have 6,200miles on it now, but since the trip, when I took it on hills, interstate driving, stop and go, it really feels quite good! So I would imagine you G8 will do the same thing once it has more miles on it, and really taking it on a trip seems like it makes a world of difference for a car. Would I love to own a G8 now? Oh ya! I would get the V8, They offer a really cool color line up too! It seems like it gets decent mileage. My only nag on the G6 is its 4spd transmission! The G8 has a 6spd, with its manual mode option! I love that! I have not test drove a G8 yet, but I should. But, it might make me want one, and I don't plan on owning a pontiac as my next car though.
 
But, I lease my cars, and the G8 is not very attracted on a lease! I like it, because it looks like a nice rounded sedan, fun, practical, economic for its fun too.

Last bit on the Australian car bit...
 
I stopped by a dealer, something like 52% of the car is australian sourced. The rest is US (30% somewhat) and Mexico.

I have read the vehicle will be made in Canada next year. I would definitely feel better if it were made here.
 
That said, I would like to see GM and Ford live. I think it is no-brainer our companies need to be able to compete in a global economy. This means we can't have the UAW striking or any other union demanding outrages packages and wages. An item is worth so much.If a competitor is producing a better product or an equal product at a better price, why would you fight for better wages? This is unheard of in a small business or even most. non-Union or small companies. Lastly anyone that has worked in factories or high tech, etc knows that people on the line can have a direct impact in quality of the product being produced.
 
Now back to the G8. My vehicle is broken in. All three vehicles I drove exhibit the subtle feel when you are on the highway and slightly tap the gas so you are neither accelerating or slowing down i.e. 4 cylinder mode. If you push ever so slightly more on the gas the slight vibration stops. Why would you expect a 8 Cylinder engine running on 4 cylinders to be smooth like an eight???. I just dove a Pontiac 4 cylinder Vibe this weekend and it feels like a 4 cylinder all the time. That is why I have always owned eight cylinders. There are eight (four on a four cylinder) cylinders firing per 1 rev of the crank shaft. Therefore, all things equal, the eight cylinder is twice as smooth.

At least the 52% makes the car a screaming success over the rest of Poniac's steel of late!

Good luck with your new ride and may you have many happy miles!
 
I test drove the base G8 and it was OK but didn't boil my blood. Looking forward to the GT next!

In the market for a new sports sedan when my current lease is up in a couple of months so I stopped in at the Pontiac dealer today to look at the g8. Salesperson told me they cannot lease this car and that the monthly payment to buy a gt would be around $600.00! I told her that while it looks like a nice car I would never pay anywhere near that to drive it-I can think of a lot of other cars that I could drive that would be cheaper than that(infiniti/bmw/lexus) I wished her luck in selling them as she is going to need it. By the way they and the dealership a few miles away have about 80 g8s in stock between them.

For $600 lease, I'm all over a 135i. Period.

Though, an amazing car, yes, there are many other cars out there that offer even more bang for the buck. I have seen a few out in town, also heard a customer of mine had bought one too, but I know he probably paid too much, when sooner or later they are going to have to lower the pricing and buy/lease rates to get them moving more. After all, this is in my opinion, pontiac's attempts to re-claim their name plate as something of quality, and I am not sure some would want to take that risk when compared to its price, and they way the hold their value.
 
Once, the rush is gone, I think I will see them trying to do most things to move them. They are piling up at my dealership, and they apparently said they are moving quite well, but that would be only to tell me, they are not desperate for my money, when perhaps they are. Its like they want to really sell them, but sometimes a company, can over do it, because creating it to be too expensive, and then leaves us walking away, there has to be a happy medium.
 
So, I wonder realistically how many they want to sell in a year, because I think a few people will dump some serious cash into it, then others will look elswhere, because they know they can get better car for $600 a month. It like a must have, and they'll in a year or so, try to sell it.
 
This sounds like I am bashing the G8,Its a great car, but when compared with pricing, best bang, overall value, others models simply beat it. If pricing can eventually come down to earth, then it will make more sense. I would think a company, in the economy that we are in, they would open the leasing more, to get them moving and out. Creating a customer base from the start.
