You just have to love GM’s pre-bankruptcy approach of throwing everything at the wall and seeing what stuck. It produced some absolutely groundbreaking ideas in production vehicles like Quadrasteer, night vision, telematics, and integrated coolers, but some even more interesting ideas were tried out, then discarded on the cutting room floor. The Pontiac Vibe GXP concept is one of those latter ideas, and it’s currently up for sale on eBay in Tucson, A.Z.
Remember GXP? Pontiac’s special sauce treatment for vehicles as varied as the G8 tire-frying wonder from down under and the Torrent crossover? More power, more rubber, more brakes, bigger wheels. The GXP line may have spawned the most ridiculous whale tail ever to grace a midsize coupe, but it also was a high water mark for retail-grade performance cars. Take the Grand Prix GXP for example. While it never quite shed the Grand-means-big-and-Prix-means-pricks, Juggalos-crushing-Faygo-while-screaming-down-the-Lodge image of its GTP sibling, the Grand Prix GXP was a great exercise in trying to make a car do stuff it was never designed for. Need more power? Transversely-mounted 5.3-liter LS V8. Hideous understeer? Reverse staggered tires with wider rubber up front. An interior as dour as your middle school principal? Give it a G meter. While the GXP treatment did transform the Grand Prix into a quick, gearbox-nuking monster, it never made it to the lower end of the Pontiac range.
A strange thing, considering how it very much could have. See, the Pontiac Vibe was largely a restyled Toyota Matrix built in GM’s NUMMI assembly plant, so it wasn’t exactly a cheaply-built snoozefest. It had proper utility, strong reliability, sharp styling, and an available 180-horsepower engine that wailed to 8,200 rpm. Unlike the Sunfire, the Vibe was actually exciting, and Pontiac wanted to capitalize on that. With that in mind, Pontiac told GM’s performance division to get to work on a functional Vibe GXP prototype.
Pontiac rolled out the Vibe GXP Concept at the 2002 SEMA show, right at the height of underglow and squash-scented air fresheners. Unlike most wild show cars, the Vibe GXP appeared remarkably restrained. A relatively subtle set of new bumpers, some simple five-spoke forged wheels, a nice little spoiler, and red brake calipers were paired with with a deep gray paint job Pontiac called Shadow Black Tri-Coat. Honestly, a bit of color-keying, removing the roof rack, and slapping on a classy set of wheels made the Vibe GXP a really handsome little hatchback.
On the inside, things change even less. Obviously the biggest interior change is the upholstery, a blend of leather seat bolsters, gray suede-like inserts, and the same gray suede-like material on the door cards. Honestly, it classes up the joint a touch, although I’m not sure if gray faux-suede has aged brilliantly. What has aged well though are the strategic metal accents scattered about. Alloy pedals always bring a touch of childlike joy, so I’m pleased to see them here. Of equal joy, special sill plates really do offer a fun sense of occasion. Otherwise, the interior of the Vibe GXP is identical to that of a production Vibe, right down to the rather annoying all-red gauges on early cars. Sure, they looked cool, but legibility wasn’t brilliant.
While the Vibe GXP certainly had tasteful aesthetics on lock, its main party piece was a roots-style supercharger bolted to the front of the engine. Cranking out 7.5 psi of boost and paired with a sports exhaust system, it seemed like just the thing to perk the Vibe up a bit. Unfortunately, Pontiac strapped the supercharger to the wrong engine. While Vibe GTs got Toyota’s screaming 2ZZ-GE four-cylinder engine, base models with the economy-minded 1ZZ-FE 1.8-liter inline-four had a five-speed. A discerning enthusiast can spot the 1ZZ-FE engine in the Vibe GXP by the rectangular relief in its valve cover and its pairing with a five-speed manual gearbox.
Still, Pontiac claimed up to a 35 percent increase in power and torque over the base Vibe. That base model made 130 horsepower and 125 lb.-ft. of torque, so it’s reasonable to assume that the Vibe GXP made around 175 horsepower and 168 lb.-ft. of torque. Hang on a second, didn’t the Vibe GT make 180 horsepower? Indeed it did, although it only made 130 lb-ft of peak torque at a high 6,800 rpm. Still, a GXP model making less power than a lower trim is a bit sad, so it’s not entirely surprising that the Vibe GXP was cast aside. A bit of a shame considering the chance that the Vibe GXP was actually fun. Supercharger whine is a great noise, and I’m sure the lower springs, stiffer dampers and anti-roll bars, big brakes, and Bridgestone Potenza RE730 tires provided decent cornering grin-factor for the segment. Keep in mind, the hot Civic Si had ditched double wishbones up front and the Mark IV Golf GTI felt curiously inert.
However, just because the Vibe GXP never made production doesn’t mean that Pontiac didn’t learn anything from its creation. The upper grille treatment on the facelifted Vibe is remarkably similar to that of the GXP, while color-keyed cladding became a more popular option on facelifted cars. Also, that supercharger? Believe it or not, you could eventually walk up to a GM parts counter and order a very similar one as a kit. According to autos.ca, GM rated the customer-ready kit for an extra 40 horsepower and 25 lb.-ft. of torque over a stock base-model Vibe, rather meaningful increases. Interestingly enough, fuel delivery for the supercharger was a little bit old-school as a fifth injector fattened up the air-fuel mixture under wide-open throttle. Hey, if it passed emissions certification, who am I to question it?
Autopian reader Nick Hernandez has been running one of these GM Performance supercharger kits on his Vibe for 90,000 miles and was happy to dish out some details on living with a supercharged Vibe. The supercharger itself is an MP45 like on a 2002 to 2006 Mini Cooper S, except with a special housing. While the kit is fully CARB-certified and installation is reportedly super simple, the supercharger’s unique construction means that servicing isn’t a straightforward affair. “There’s not an obvious access panel. I’ve serviced the snout and replaced the coupler up front and the oil, but I don’t think I can get the rotors out that way,” said Hernandez. Happily, a rebuild hasn’t been required in all 90,000 miles of supercharged operation. As Hernandez put it, “I’ve had no issues with the supercharger itself or anything like that.” All smiles, then. Good stuff.
Still, even if you can get your hands on a GM Performance supercharger kit, it’s hard to beat owning the actual Vibe GXP. However, just because you can own it doesn’t mean you can drive it. Because the Vibe GXP was very much a prototype vehicle, it can’t exactly be titled. Still, someone’s driven it at least a touch over the years, as the odometer appears to display 2,254 miles. While a list price of $15,500 is expensive for an economy you can’t drive, what’s a one-off slice of GM history worth to you? For the right person, the Vibe GT could be an awesome part of their collection.
Bought a new launch “TRD” Matrix XRS in 2003. The TRD tuning kit was a dealer install kit that you could buy piecemeal & maintained full warranty, pretty sure this vibe has everything they sold from 2003-04. TRD Supercharger, piggyback ECU & injector kit. “TRD” brakes (stoptech) “TRD” coilovers (KW V1), TRD lsd, “TRD” axel back exhaust (USA made I think). There may be some other odds & ends but mine was the only one I ever saw with whole “kit” before was discontinued in 04. Very confusing with the 2004 & up TRD matrix that’s a XR with wheels & a exhaust tip
Edit XR not XRS
TRD made a supercharger for the 1ZZ. I have a corolla with the 1ZZ, and it will take literally anything you can throw at it. While the 2ZZ was great in stock form, there wasn’t much head room left.
The only way to do this right would have been a twin turbo 2JZ driving the rear wheels, but unsure if the ‘rolla/vibe platform would have been amenable to that.
I’d rather have 2JZ in my car than Jay-Z. Just sayin’.
The Solstice GXP wheels work really well on this, wow
Given how slow the Vibe 1.8 was, I’m extremely dubious that this makes the car “fun”. Less painfully slow perhaps, but even 40 HP isn’t going to make one of these a firebreathing hot hatch. ND for a car you can’t even legally register.
Drop a zero from that price and it might make an intriguing track/autocross toy though.
I love the Vibe, but this example is NOT worth $15k LOL, maybe $1500
Like you said, you were able to buy that supercharger kit from the dealer.
Maybe Florida will let you title it, or some state that does title washing or whatever. But still not worth $15k
My uncle had a first-gen Matrix base with the 5 speed. It was just such a useful car. Just enough space, just enough power to not be painful, and things like the hard rear floor to make it easier to use. I borrowed it to haul something up to a second property a couple hours away and never once felt hard done by.
Toyota was really good at “right sizing” their cars.
It is too bad they never produced these, but I also can’t imagine buying a “museum piece” Pontiac Vibe. If you could title it and drive it, maybe.
There was a boosted one for sale in my neck of the woods some time ago. I think it was at the Japanese importer, must’ve been a trade in our something. It was one of those projects someone spent way too much on, and somehow not nearly enough? But who am I to judge.
Found the old ad. 6psi, supporting mods… This would’ve been fun to rip around in.

GM has the among the best engineers in the auto industry, and the worst managers. I get sick of seeing all the amazing cars GM produced one concept version of, then shit canned it to make another anonymous crossover.
This.
They should require engineers to make up at least half the executive board.
That’s not a bad deal for what’s basically a brand new (2,254 miles), fun, reliable, good looking economy car.
I don’t remember the last time I had a VIN actually checked since I escaped California 18 years ago.
I could probably buy my neighbors broken down, moss covered Vibe (he gives off a broken down moss covered vibe btw) for cheap and register the new one as that.
Honestly, nobody cares about rules and regulations where I live. It’s the car wild west in out here.
Nobody would ever know. I’d drive it as a daily.
What? Some cop who happens to be an Autopian reader gets behind me one day? Probably just give me a thumbs up and a wry smile.
Just make sure you get an agreed value auto insurance policy.
I haven’t had auto insurance for my last 22 years of driving. It’s a scam.
I’ll keep my money and invest it.
That’s 22 years of not paying X amount of money per month for basically nothing but peace of mind.
It’s like riding a bike without a helmet I know.
Maybe I read too much Hunter S Thompson growing up. You think there are rules, there aren’t.
You must be in a state with the personal responsibility rules (Virginia or New Hampshire) or that you have posted a surety bond for the state minimum (most other states).
I only mention this so that you are aware of the situation that you can be held liable for damage to others and they could go after your investments.
Food for thought. Thanks.
Ah, so you’re the reason everyone else has to pay for uninsured motorist coverage. Thanks for that.
We all make our own choices based on risk aversion, our own perceived skill and imagined consequences. You’re an adult I’m not making you buy anything.
You don’t” have” to pay for anything you don’t want to. You weasel brained inebriate.
You must spend a lot of time at casinos!
No. I went to one once. I consider them to be gross, sordid and depressing places.
I recognize that might offend some people. Nobody likes “no insurance guy”. But past monetary predicaments at one point left me no choice. Couldn’t afford it but still had to get to work (In a rural area, before smart phones and Uber). That $135 a month they wanted to charge me when I was 17 years old making $7.00 an hour went to barely paying rent.
Who here can honestly cast a stone when you consider the fact that the US government made it illegal not to buy it.
Who does that effect the most?
The poorest.
Sorry if you now have the difficult choice of paying minimal X + per month for uninsured driver protection. I’m guessing you check that box because you can afford it. Because your vehicle is worth (gotta be at least 5x) more than mine.
Somehow that thought pattern stuck with me.
Now let me tell you something about car ownership and poverty.
Driving illegally and without the advertised protection for any number of years is not careless bliss. It’s head on a swivel, pay close attention to everything driving.
Example: I don’t trust green lights. That green doesn’t mean go! It means check your surroundings and proceed with caution.
I know the idea of “risk compensation” is a so far just an unproven theory.
But I’ve lived it for 22 years.
Fuck insurance companies.
Unless you’re rich enough to not care They are raping you monthly. No thanks.
And fuck anyone that tries to tell me I need one. It’s a joke for anyone at the bottom of the pay spectrum. You want me to pay you so I can drive like a shithead? How about I’m just careful instead? I do just fine without the padded helmet.
Thanks for the offer though.
I’ll just go on paying attention to my surroundings when driving instead of relying on bullshit insurance.
I owned a 2003 Matrix XRS and while I enjoyed driving it on curvy roads at highway speeds it was a dog around town. That high-revving motor made what seemed like 0 HP under 6,000 RPM and only got fun at close to 8,000 RPM. It was exhausting to drive, especially with the 6 speed.
It was my first car after getting married and I thought it was the perfect dad wagon since it was practical and sporty. I didn’t hate it but I also didn’t love it. It also had a ton of problems from the factory. All the door seals fell off because I assume they didn’t use the right adhesive so those had to be reapplied. The wheel speed sensor stopped working within a few days and I considered leaving it like that since the odometer wouldn’t increment but it meant no ABS so I got it fixed. Finally, the interior plastic panels were complete crap and would pop off on a regular basis.
Going with a boosted 1ZZ is a much better idea than a NA 2ZZ. Owners of the 3rd gen Toyota MR2 know this and they have seen amazing results boosting their 1ZZs. The 1ZZ is bullet proof. The 2ZZ is a high-compression engine and can’t take added boost.
As someone with a Torch-like fetish for gauges, I LOVED the Pontiac all-red gauge bit. It was the next step after the tron-grid-pattern backgrounds of the ’80s and ’90s.
Just screamed Pontiac, nearly as much as an illuminated PONTIAC on a trunklid. That was my favorite.
RIP the brand that built (cheap) excitement.
I had a Grand Am GT that was one of my favorite cars I ever owned. The all red dash was fantastic at night time. I HATE that most cars have a ton of night vision wrecking blue and white on their displays and screens these days.
A friend’s wife had a Vibe. Got to drive it once ( I was the chauffeur on their wedding day), (yes, in the Vibe), and I remember it having a nice feel to the stick. More power would have been welcome.
Damnit, now I really want to find a Vibe & one of those kits.
I know exactly what it would sound like: WHEEeeeeeeeee…..
Great! Like a supercharged Elise with 30% less volume; on the big cam with supercharger whine at 8000 rpm it’s very exotic sounding.
Not the same, but I had an ’04 Matrix XR. I loved that car. Fun, reliable and so practical. It was condemned by the local Toyota dealer for dangerous frame rust at 85,000 on the ODO, in 2017 I think. They said they would not work on it. I was going to give it to my daughter to get to school. So I let it go for scrap and bought her a gentle-used Fit instead. I wrote Toyota to complain that this was unconscionable. They said “Hey, it’s not a real Toyota”. I was so pissed. But I would buy another.
Not a real Toyota? It’s a Corolla wagon, built in the Cambridge Toyota plant alongside other “real Toyotas” I’d be curious to see their justification that it’s not real.
Sidebar, that always weirded me out, that the Matrix and Vibe were built in different plants.
I’ll track it down. Something about sourcing. It’s been a while.
