Click on the image above for our high-res live gallery of the 2010 Pontiac G8 ST

Even the most die-hard enthusiast, dreaming about the 361-hp 6.0-liter V8 under the hood of the upcoming Pontiac G8 Sport Truck, must be having second thoughts about the cost of feeding that thirsty powerplant. With fuel prices rising significantly in just the last few months, the folks at Pontiac are rumored to be considering a six-cylinder option for the G8 ST. The engine, if it finds its way under the hood, would be the same 256-hp 3.6-liter V6 found in the entry-level Pontiac G8 sedan. Not due until the 2010 model year, the V6-powered G8 ST would share the sedan's EPA fuel economy ratings of 17/25, making the sport truck a more feasible for buyers that want to jettison their daily-driven pickups for something with better fuel economy and a bit of utility.

      Seems to me that someone who needs to carry an appliance home from the department store is better off driving a compact car that gets 35 mpg and spending $20 to rent a compact pickup truck from UHaul for the hour a year they actually need the pickup bed.

        We have a winner!

      How about a happy medium. 3.6 DI w/300HP , non-DI & V8 options are dropped all together. I've always preferred V8 power plants, but these modern DIv6's are swaying me away.

      You get the power, you get better fuel economy, GM gets a slightly better corporate average and you have a stylish pickup.
        • 6 Years Ago
        If you're going to mention engines, don't forget to mention swapping the 5-speed auto currently paired with the G8's V6 with GM's 6-speed auto for maximum performance and efficiency. Heck, for that matter, toss in a tuned version of GM's turbo 2.0L Ecotec and pair that up with a 6-speed manual for maximum fun with decent fuel economy.

        Incidentally, the DI-V6+auto would be a much smoother cruiser than the turbo-4 w/6MT and would likely hit a different market and price point depending on standard/available equipment.

        Wishful thinking.

        The V6 Pontiac G8 DOES get 17/25.

        And FYI, the 6.0l V8 in the G8 gets 15/24, which isn't awful considering the size and power increase of the engine.
        • 6 Years Ago
        Exactly.

        And, Hyundai's Genesis can get 17/25 MPG on its 4.6L V8 @ 375hp, why can't Pontiac G8 with the smaller 3.6L V6 @ 252hp?

        joe97:
        The article says the G8 V6 Sport Truck would get 17/25. So I don't really understand your question.
      • 6 Years Ago
      So what do you think is GM's sales target for this car and do you think they will honestly meet it? I don't know how well the G8 itself is selling. Like I mentioned earlier, I've only seen one on the road but that's just me. I just feel that the resources used in producing this car would be better if they were diverted to smaller cars, which are in obviously high demand right now.
      On another note, I know the history of 'utes. All I'm saying is that towing something with a 'ute is tantamount to towing something with a sedan, which you rarely if at all see.
        • 6 Years Ago
        The G8 sedan's target was 30k annually which is as many as Holden can build. I'd imagine the G8 ST's is 10k or less targeted. But remember these are profit for GM as almost no additional engineering was required. All they did was replace the lion with an arrowhead and change the grille to a split grille.

      i think it looks cool, and should offer a TT 6, or maybe one of those new 4 lobers and drop the 8.
      2 seats, maybe you only want 1 passenger.
      truck-ish bed... for people that are only sort of truck-ish?
      towing? really now, if anyone needed to do real towing of greater than 3500lbs then they should be looking at a more traditional truck/suv/van that is expected to tow.

      i'm thinking decent power, rwd, bed if you need it... what else does it need?
      • 6 Years Ago
      I believe the time is absolutely right got the G8 ST. Sales of large trucks are falling, as they get awful mpg, whereas the sedan baseds ST gets MUCH better mileage. In fact I would suggest that the ST may be the BIG BIG winner for GM, as truck buyers convert over to this machine. If you visit Aussie and other countries this type of machines is bought in huge numbers.
      That said I think the discussion of the smaller V6 versus the V8 is pointless. After all the V6 ONLY gains ONE mpg over the 6.0L V8 engine.

      Think of it this way. Do I want a large truck, getting 15 mpg, or do I want a sexy powerful G8 ST which goes faster and gets far better mileage......
        • 6 Years Ago
        I was thinking the exact same thing! The majority of people don't really need the capability built into the larger, body-on-frame trucks. Those that do will still buy those, and the people who thought they needed them will probably realize that something such as this will serve them just fine.

      Thanks, Autoblog. I will never be able to purge these abominable images from my mind, as they have been burned deep into my cerebral cortex.

      I smell Aztek.

      Please, someone just let Pontiac die already.

        "I will never be able to purge these abominable images from my mind, as they have been burned deep into my cerebral cortex."

        Fret not Silver, a quick and simple lobotomy will ease all your cares away. Never say never, you just have to want it enough. Go now... before pictures of a conservatively-styled unibody truck haunt your existence any further.

      I thought companies were going more green with cars. These high performance cars will continue to hurt the environment. But sometimes who can resist power on the pedal and doing 100MPH in 10 seconds.
      • 6 Years Ago
      The G8ST should have the more capable 1800lb Capacity of the V6 Here.
      • 6 Years Ago
      Here's a better idea: don't produce that chimera of an automobile at all. To the guy who wants to use this to tow his jet-ski and boat: what are you thinking? Recall that this is NOT a pickup truck or an SUV. It is a Pontiac G8 chopped into the shape of a pickup truck. Would you use a G8 to tow something? Probably not. If you want a G8, get one, because it's one of the better American cars out there (although I have only seen one on the roads since its launch). However, write to GM and tell them not to produce this beast, since it will only push them further into the hole.
        • 6 Years Ago
        I don't see why you couldn't use the G8 to tow. I used to use my 96 Roadmaster Wagon to tow a 4000lb boat. It had no issues doing it.

        How difficult can it be to drive a Tacoma? Is there a skill set I'm not aware of?
        • 6 Years Ago
        I would disagree, I think there's a good market for smaller trucks, especially since this is the coolest looking truck on the market (IMO).

        My friend bought a Tacoma, because he had to have a truck for some reason. Don't ask me why, he's never towed anything and I don't believe anything has ever been in the bed. And he's horrible at driving it. Now he's trying to get out of it because gas sucks. And he's not the only person like this. This truck would be perfect for him.

        Matty apparently has no idea what the roots of this vehicle actually are... or what people use them for where it originated...
      • 6 Years Ago
      It looks vastly better as Holden intended it to look wearing either Holden or Chevrolet badges.

      Why this and the sedan aren't being sold through Chevrolet here like they virtually everywhere else outside of Australia blows my mind.

        • 6 Years Ago
        I have a theory for this. Most people wonder why the G8 wasn't the Chevy Impala. I can think of 2 reasons for this. One, the current Impala sells quite well and has a reputation for reliability and economy in a big car. It really has no competitor on economy and size for the price. Most of Impala's customers don't care if its RWD or FWD, or what's under the hood. They simply want reliable roomy transportation. Why waste selling them an RWD V8 that will hit your CAFE average when they likely didn't want it in the first place.

        Pontiac's customers are different. The Grand Prix didn't fit Pontiac. Pontiac's customers actually care about V8 power and RWD in a much higher percentage. Most of G8's buyers aren't buying it just because, they specifically want an RWD V8 sedan. The BPG dealer by my house has a few used 3-series sedans in its lot.

        Also I don't think Holden even has the capacity to build the G8 in the numbers it would sell if it were an Impala.

        I also surmise that if G8 proves to sell well over the years maybe the rest of Pontiac will become Holden-ized.

        So in short.
        1) Selling Commodore as a G8 lets GM keep the volume down vs Impala but still offer a V8 to its fans that want one.
        2) Commodore fits in Pontiac quite well

        Now I really can't understand why the higher trimmed Commodore-based Holdens aren't Buicks.

      People seem to think v8 = gas hog, I have a 1998 s10 blazer with a v8 out of a suburban that gets 26 on the highway.
        • 6 Years Ago
        I'm assume you swapped in the 5.3L V8? That's a very efficient V8. But V8s are seen as gas hogs because with the exception of GM's pushrod V8s they are gas hogs.

        Just compare the 4.6L N* to the 5.3L LS4 in Buick's large sedans. Compare the Mustang's economy with a 4.6L V8 to the G8's with a 6.0L V8.

        The pushrod Chevy V8 will be the only one to live on in an affordable fashion. Its nearly as efficient as DOHC V6 engines, despite being more powerful, similar in size and in many cases cheaper to manufacture. GM has direct injection and other fuel saving tech coming up for the Chevy small block.
        • 6 Years Ago
        Yes, but you put large engine in smaller truck.

        Most V8s do get bad gas mileage, because... they are in large Suburbans.
        • 6 Years Ago
        You drive a blazer on the highway by choice? Wow...just wow.
          • 6 Years Ago
          98 blazer v8, lowered and coil over suspension, seriously done up, I autocross and will whoop just about anything for sheer torque out of the hole. Mustang GTs and STI's know exactly what my tail lights look like. So yeah I cruise on the highway.
