Default -Praise for the most powerful Pontiac ever

Quote:





UOTE]The best Pontiac in Pontiac history just got better. The rear-drive G8, hailed here at AutoWeek and elsewhere in the wheeled world in its original rear-drive, 361-hp, 6.0-liter V8 form, now has a mighty 415-hp 6.2-liter V8 driving those rear wheels, making it the most powerful Pontiac ever.

"Now wait a minute," you say. "What about the (fill in the blank) Pontiac of (fill in the musclecar hero year of production)?"

No, that model was not more powerful.

"They measured horsepower differently then," product manager Brian Shipman said.

If they measured this one the way they did those old cars it would have more than 500 hp. And that ancient Pontiac of yore couldn't turn or stop, as you may remember if you ever drove one.

To get all that torque to the ground, this one has a "race-tuned suspension" that was "tuned at the Nürburgring." That means an FE3 suspension with firmer front struts and shocks, a 20-mm rear sway bar that is 2 mm bigger than the regular G8's, and 19-inch wheels wrapped with 245/40 summer tires.

But the biggest difference between this and the rest of the new Pontiac G8 line is the availability of a six-speed manual transmission. We know, we just drove one for a week. (While the official word from the division at the G8's launch a year ago was that there would be "no manual in the G8," one has mysteriously appeared anyway, offering better access to those massive, meaty torque and power curves.)

We took this miracle of modern Pontiac engineering (or Holden engineering, depending on your perspective) and flung it about L.A. It is a lot of power.

As with many a power hog, this one is a little more difficult to master while cruising delicately through suburban streets. The 415 lb-ft of torque requires an extra-beefy set of gears to keep from blowing apart during spirited driving, but that beef makes it a bit clunkier in city maneuvering. We never fully mastered the art of gently engaging the TR6060 manual during our week with it. You, however, are probably a better driver and will get it right off the bat.

An added irritant was the 1-to-4 shift-lockout mechanism that we have hated with a fiery passion since it first appeared on Corvettes and Camaros in the early 1990s. Why, oh why, can't they get rid of this?

The short-throw shifter is more at home being hammered on a track or on a twisitng mountain road. There you can better get the feel of proper engagement and effortless smoothness that will impress your passengers and garner you better lap times. You can shift all the way up to the fuel cutoff at 6,000 rpm.

At a track or from a stop light you will also better appreciate the 415 hp. It comes from the LS3 V8 with a promise a 0 to 60 mph time of 4.6 seconds and a quarter mile of 13.2 seconds at 109 mph, Pontiac says. Top speed is listed at 150 mph, limited by cooling and tires. A Track Pack that will add coolers for the transmission and engine oil is coming but no date has been released for when.

Stopping is equally impressive, with larger, 14-inch, four-piston Brembo brakes in front.

The FE3 suspension is plenty firm for cornering while not beating you up on placid, straight highways. It doesn't bounce, either. It's a nice accommodation for both uses. You could put kids or in-laws in the spacious back seats and not feel guilty.

The inside also gets standard leather, six-way power seat, six-CD 230-watt audio, Bluetooth, OnStar, XM satellite radio and 10 cupholders. Old Pontiacs didn't have any cupholders.

Outside, the GXP gets a new front lower fascia, rear diffuser, tapered chrome tailpipes and three GXP badges.

Will it beat the BMW M5? The Cadillac CTS-V? The Audi S6? Sounds like somebody needs to rent a track and find out. Those competitors may be a little more refined, with interiors that rate higher on those nebulous luxury scales that focus groups always try to figure out, but the sticker price for the GXP is expected to be under $40,000 when the car comes on the market in late January. And remember, the G8 GT stickers at $32,495 and the six-cylinder base model is just $28,875.

Pontiac will make "5,000 or so a year," but that is not production constrained, so buy all you want--they'll make more.

Default 2009 Pontiac G8 GXP - Short Take Road Test

Quote:
The 2009 Pontiac G8 GXP is just the sort of four-door Corvette Americans have long prayed for, with sharp steering, fabulous response from the four-piston Brembo brakes, exceptionally balanced and neutral handling, and a simple and classy look to the interior layout and trim; all for a price that undercuts a comparable BMW by $20,000.

Too bad that its timing is so lousy. On the eve of the GXP’s debut as the most powerful of the Australian-built, Holden Commodore–based Pontiac G8 lineup, the U.S. car market is slogging through its worst sales slump since 1983 and General Motors is estimated to be four to six months away from running dry of cash and going bankrupt.

Even if the GXP is a failure, it will at least be remembered as the most powerful stock Pontiac ever.

I’m Gonna Need at Least 400 Horsepower to Get the Kids to School

As with Holden’s HSV GTS, the GXP’s most direct Australian ancestor, the top G8 uses the 415-hp 6.2-liter LS3 V-8 derived from the Corvette’s engine and paired with either a six-speed automatic transmission or a six-speed Tremec manual, the only stick offered in the G8 line. Although the LS3 V-8 is designed to run Active Fuel Management, GM’s cylinder-cutoff system, program planners decided to leave it off the GXP, because it would have dropped engine output by 20 to 30 horsepower.

Instead, the GXP gets the hated 1–4 skip-shift system on the six-speed manual, which blocks out second and third gear under low-load driving. This forces the driver into fourth gear early in an effort to save fuel. Though it doesn’t prevent the GXP from drawing a gas-guzzler penalty, the fairly aggressive (intrusive) program at least minimizes the tax. The Internet is thick with do-it-yourself disconnect instructions for the Corvette, so owners should be able to disable the function fairly easily.

The net effect is a composed, if slightly soft, blacktop cruiser with the power to light ‘em up and rip off 4.7-second sprints to 60 mph. The quarter-mile takes just 13.3 seconds at 109 mph, the LS3 rumbling and roaring with just the right V-8 snort. Tremec’s latest six-speed shifts with slick satisfaction and accepts downshifts willingly. Too bad this transmission is only available in the GXP.

Australian Birth and German Training

Final chassis tuning was done at the Nürburgring, and the result is a truly likeable machine with deft, Euro-sedan handling. In a nod to America’s generally lumpier roads, the FE3 suspension pack has retuned shocks and a 2mm-thicker rear stabilizer bar but is kept supple with ample wheel travel, which prohibits fitting any wheels or tires larger than the standard 19-inch polished alloy wheels and somewhat conservative 245/40 W-rated Bridgestone Potenza RE050As.

We recorded 0.85 g on the skidpad, a figure that doesn’t do justice to the poise this car exhibits. Four-piston Brembo calipers up front haul the GXP to a stop from 70 mph in just 156 feet, although we noted a fair degree of fade after just three hard stops.

GM is hoping to move 5000–7000 GXPs per year, but sales of the G8, introduced last February, have been off Pontiac’s predictions by over 50 percent thanks to high fuel prices and America’s soft economy. The GXP’s base price will be about $40,000, including a $2000 gas guzzler charge, when sales begin in December.

There’s not much in the way of visual distinction from the base G8: a blockier front fascia, the bigger wheels, seats and dash accented by GXP logos, and a unique squared-off steering wheel. And options are few: a sunroof, all-season tires for colder climates, and a dealer-installed “Track Pack” which includes upgraded transmission and engine oil coolers. The color choices are even the same as the base G8.

Cars like the GXP—if not GM itself—may soon be extinct, because fuel-economy standards due in the next five years will make their business cases extremely challenging. Grab one now if a big, comfortable, well-trimmed sedan with Corvette-like performance is what’s been power sliding through your dreams.

If I was BigElm I would get that over the V8 Genesis,about the same money.Stick shift,same mpg(maybe),just a little rough around town.

I like it..Just think what GM could put out with cheaper operating costs.

Not bad... not bad at all! Driving light trim looks like it was taken directly off of an 06-07 WRX. Probably has been said already. Many times.

I'm wondering if it looks better (and feels solid) in person. I generally don't care for the way matte black/gray finishes photograph, especially when lit mid/high-key w/ strobes. Not holding my breath, since it is Pontiac after all (all my Pontiac rentals lately were garbage on the inside), but it might be worth checking out.

GXP - non supercharged version of the Corvette V8
CTS-V - supercharged version, altho less powerful supercharger than found in the ZR1

i'm not sure if the engine displacements are identical or if the suspension config is the same?

Someone tell me that both sedans (CTS and GXP have actual proper rear multilink suspension sets given they have the room and are both boxy sedans)

I wouldnt be surprised if they both have the same basic chassis

All the right lines are there, just drop in some contrast stitched leather and brushed aluminum bits and it would be a champion.

I'm also wondering if this car got the new ultradope rear end they developed for the CTS-V, but this is GM after all and I fully expect them to do the wrong thing.

I like that the speakers are higher in the doors. I wish more companies would do that instead of firing the mids into your ankles.

I don't think they are on the same chassis. The CTS is on a Sigma II chassis, while the G8 is on the Zeta chassis.

I have a GTO now, but this would make a pretty tempting alternative to it if I needed four doors...

What about the rear suspension setups? I thought the classic rear leafspring config in the Corvettes was purely a function of the car's low body height and stance. They don't really have this excuse in the boxier sport sedans.

it's such an awesome care. It really stinks that it's sales have been horrid so far. Now that the manual is coming out, hopefully sales will pick up and they keep it around. It was supposed to be a mover for GM and hasn't done so. Hope it doesn't go the way of the GTO.

yeah; fantastic deals should be had on these considering they are going to try to move 5000-7000; I can easily see $35-36k for one of these.

Doesn't matter... it's the economy in general. Even paying $2/gal right now is tough for people. We'll see what happens to gas prices by summer '09 as well... something tells me that when the other shoe drops on all these cuts in production, we could be seeing gas prices the likes of which we've never seen before (and not in a good way). And then there's these damn pirates...
