As you might remember, we were left unfulfilled by the 2012 Buick Regal GS. Buick just didn't go far enough, in our estimation, which is why when we read about the possibility of a tuner version of the GS from SLP Performance Parts on Inside Line, we got on the phone posthaste.

SLP is best known for building the Firehawk and SS versions of fourth-generation F-body Pontiac Firebirds and Chevrolet Camaros for General Motors, and owning the "ZL" trademark that both it and GM have used on the current-gen Camaro. But the company is also the rights holder of fabled Buick monikers "Grand National" and "GNX," names that it intends to put back into play.

An SLP spokesman confirmed the report that a 300-plus-horsepower Buick GNX based on the GS is in development, saying that it should have a final mock-up based on the above sketch by the middle of this month. But SLP also told us that it has plans to revive the Grand National name, which would presumably fall somewhere between the GS and the GNX on the performance scale.

But before we get too lathered up about this, remember that SLP has dipped its toes in the performance Buick game before, with middling results. The company rolled out a Buick GSX back in the early part of last decade, based on the supercharged, 3800 V6-powered Regal GS. This dealer-installed kit was a good idea applied to the wrong car, as the front-drive, fourth-generation Regal just wasn't enough of a performance machine out of the box to bother with.

The current GS, on the other hand, offers a much more intriguing proposition for a little bit of aftermarket improvement. As long as SLP does the full-blackout treatment that was a hallmark of the original GNX, we'd be willing to take it for a spin.

      Wait.... why not just bring AWD and the ~325 hp 2.8 Turbo V6 from the Insignia OPC over?

      Lame. As someone who owned an 87 GN, it is heresy to use the GN or GNX name on a 4 door, front drive, inline 4, jelly bean car. 300hp or not, it aint no GN! If Buick was smart they'd bring back the original design and platform, aka mustang/camaro, and give us back our badass sinister turbo v6 terror!

        Agreed has to rear wheel 340plus turbo six speed manual would be slick matte black paint with matching 19" wheels then I would buy it and put it in the garage next to my 87 and buy a damn bumper sticker that says think this GN is fast you should race my other one!

      It's not a GN if it's front wheel drive....

      If this is to be positioned above the current Regal GS (which it should if HP figures are correct and it is to properly carry on the GNX/Grand National name), then it will be priced WAAAAYYYY out of market in my opinion. The Regal GS is so poorly positioned in terms of price if you ask me. I will say I'd be in favor of a performance division of Buick though. I've been wishing to strap a supercharger on an AWD LaCrosse and have a real street sleeper (albeit needs to lose some weight)---and call it a Wildcat for nostalgia. If Buick wants to keep building on lowering the age of the average buyer, this would be a good follow up to the current lineup they are working around. Market them to go after the Japanese brands, and leave Cadillac to beat up the Europeans.

      RWD or it is not a Grand National/GNX

        I might be ok with calling it a Rgal T-Type even in FWD tho.

      Not interested, at all personally. Someone who still to this day thinks that the GN and GNX were the coolest cars Buick ever made, and in the top-10 best GM cars list for sure, this is just showing how out of touch things are with GM that they haven't MADE this legitimately, and that enough people buy this stuff that SLP can do it? I mean, SLP is a good tuner, but not in regards to stuff like this, especially the platform they're building it upon as you can't shine... If the GN/GNX name comes back, it should be on a black/grey 2-dr RWD Turbo coupe. Vader 2.0. Make it a retro, just with carbon fiber and hyperblack metal bits.

      If I recall the conclusion of the AB review of the GS, it was that it is a good car, but just not a good value proposition. I'm not sure how adding 30hp at a significant cost adder (tuner-driven) will make the value any better. I agree with RocketRed that the GS needs to go on a serious diet. Buick also needs to revisit its pricing model. I would think that with production in Canada now instead of Germany, there would be lower production and shipping costs that could have been passed on by way of lower sticker price. Unless, of course, it was a money loser while being sourced in Deutschland.

      1. It needs to be AWD or preferably RWD. 2. It needs a powerful turbocharger, and a top of the line V6. 3. It needs to be available only in Black, with no chrome or any other color for trim work. Personally, I think they should call it GSX, as the GNX is legendary, and should not be tampered with. The GSX should live up to the '70 Skylark. If they go this route, the car should be available (for the first year) in Apollo White or Saturn Yellow, with the black stripes. Then additional colors (hey Buick, remember those?) should be available the following year. In either case, it needs to be a performance MONSTER.

        It won't be RWD, it might be AWD, but I don't think there's a good way to make it RWD and affordable. Stripes would look really stupid on this thing.

      I understand it handles well and rides like more expensive euro cars but it's raw performance leaves something to be desired. The GS just isn't powerful enough to compete with a Toyota Camry so comparing it to the legendary Buick GNX is wrong. That car was a Corvette killer, this one might compete with what...a Sonata?

        And what was wrong with the supercharged 3800 anyway? All it needed was power sent to the right set of wheels

        Yes, it was a Corvette killer. But that was only because the Corvette was a horrible car during that era.

      puh-leeeeeese make sure it's actually fast. Really fast. Sub 5 seconds is the only thing to make this process worthwhile.
