2009 SLP Pontiac G8 GXP Firehawk: The Evolution of a Modern Muscle Legend
The SLP Pontiac G8 GXP Firehawk is one of the rarest and most potent performance sedans to emerge from the final days of the Pontiac brand and exemplifies the unique role that SLP Performance played in American muscle car culture. It fused Pontiac’s last rear-wheel-drive halo car, the Pontiac G8, with a supercharged performance package that pushed the boundaries of what a four-door American sedan could be. Though only produced in limited numbers and for a very short period, the G8 Firehawk stands today as a highly collectible, low-production performance icon with deep roots in both Pontiac’s heritage and SLP’s storied modification legacy.
Origins: Pontiac G8 Meets SLP Performance
The Pontiac G8 itself debuted for the 2008 and 2009 model years as a powerful, rear-wheel-drive sedan imported from Holden in Australia. Built on the Zeta platform, it was offered in three trims: a V6-powered base model, a G8 GT with a 6.0-liter V8, and the top-tier G8 GXP with a 415-hp LS3 V8. The G8 marked Pontiac’s return to true performance sedans and was one of the brand’s last vehicles before its discontinuation in 2009 amid General Motors’ restructuring.
SLP Performance Parts (Street Legal Performance) — a company known for high-performance conversions such as the Firebird Firehawk in the 1990s and early 2000s — decided to leverage this new muscle sedan platform and give the G8 a boost worthy of the Firehawk name. The Firehawk badge had historic significance for enthusiasts thanks to previous SLP-modified Pontiacs, and the company aimed to bring that performance heritage into the modern era with the G8.
Firehawk Revival: 2009 Pontiac G8 Firehawk
Package Overview
The SLP G8 Firehawk debuted in 2009 as a dealer-available or SLP-installed package for select G8 models, most commonly the G8 GT and the high-performance G8 GXP. These cars were not factory-built by GM but were created by taking new G8s — or in some cases lightly used examples — and sending them to SLP’s facility for extensive performance and cosmetic upgrades.
SLP equipped the Firehawk with major enhancements aimed at both power and handling, including:
- SLP TVS 1900 Supercharger producing around 500 hp on the GT base engine
- SLP Blackwing cold air induction system for improved airflow
- PowerFlo® stainless steel exhaust system for freer breathing and deeper sound
- Sport suspension package for improved dynamics
- Distinctive flat-black hood treatment and Firehawk badges
- 19-inch Firehawk wheels and performance tires
- Optional Competition Brake Package for track-worthy stopping power
SLP also added interior touches such as a numbered plaque, embroidered headrests, Firehawk floor mats, and a certificate of authenticity — giving owners a documented example of the performance model they purchased.

Production and Rarity
Unlike typical factory figures, SLP didn’t release official comprehensive production numbers for the G8 Firehawk. However, enthusiast registries and auction records help paint a picture of just how exclusive these cars were:
- Approximately 29 total G8 Firehawks are believed to have been built, with a mix of both GT- and GXP-based examples.
- Within that total, about nine were built off the high-performance G8 GXP platform — making these cars among the rarest of all Firehawk examples.
This rarity, combined with performance figures that rivaled many modern sports cars of the era, make the G8 Firehawk one of the most sought-after late-period Pontiac models in the collector market.
Models and Trim Levels
SLP did not produce separate factory trim levels as GM does. Instead, they offered convertible supercharged packages for existing G8 trims. The two principal Firehawk variants — based on the underlying G8 models — were:
G8 GT Firehawk
- Based on the G8 GT, which came stock with a 6.0-liter L76 V8 producing about 361 horsepower.
- SLP’s supercharger and associated upgrades boosted output close to 500 horsepower.
- The package included performance chassis upgrades, exhaust, intake, and cosmetic enhancements.
- This version was the more commonly modified Firehawk and represents the core of the limited Firehawk production.
G8 GXP Firehawk
- Based on the already potent G8 GXP, equipped with a 6.2-liter LS3 V8 and enhancements such as Brembo brakes and sport suspension from the factory.
- SLP took this potent platform even further, with some examples reportedly exceeding 550 horsepower with supercharging and tune upgrades.
- Only around nine GXP Firehawks are documented, each with unique specifications and often delivered with manual transmissions and competition brake setups — making them extremely rare and highly collectible.
There were no other “official” Firehawk trim levels beyond these modified versions; any naturally aspirated G8 models remain standard GT or GXP Ponitacs, not Firehawks.
Performance and Driving Experience
Performance figures for the G8 Firehawk impressed even seasoned automotive journalists when the car debuted. The supercharged Firehawk was capable of:
- 0-60 mph in around 4.3 seconds from the GT base, following SLP’s power and suspension upgrades.
- Quarter-mile runs in the low 12-second range at over 115 mph.
Thanks to its rear-wheel-drive layout, powerful V8, and dedicated performance enhancements, the Firehawk handled not just straight-line runs but also delivered improved chassis dynamics compared with a stock G8. Typical upgrades included progressive-rate springs, upgraded sway bars, and optional Brembo brakes — essential for taming the car’s enhanced output.
Historical and Cultural Significance
The SLP Firehawk nameplate has a long history in Pontiac culture, originally associated with high-performance Pontiac Firebirds in the 1990s and early 2000s. These cars themselves were dealer-modified performance variants built by SLP, and they helped uphold Pontiac’s performance image during years when factory muscle cars were less accessible.
Applying the Firehawk name to a late-era Pontiac G8 was a nod to that heritage and sought to create a modern interpretation of Pontiac performance ethos — a powerful, street-legal muscle car rooted in American performance tradition.
The G8 Firehawk thus serves as a bridge between the classic tuner days of SLP Firebirds and the modern performance landscape — and also represents one of the last new performance Pontiacs ever created, given Pontiac’s closure in 2009.
Collector Appeal and Legacy
Today, the SLP Pontiac G8 GXP Firehawk is a highly collectible vehicle, not only because of its rarity but also because it showcases what Pontiac could achieve when unfettered by corporate constraints. Its limited production numbers (estimated around 29 total units) make original examples extremely desirable at auctions and private sales.
Collectors prize documented examples with strong provenance, especially those with the GXP based platform, manual transmission, and full SLP documentation including numbered plaques and accessories. Firehawks have commanded significant attention relative to standard G8s, partly due to their exclusivity and performance pedigree.
Because the Firehawk was produced during Pontiac’s final model year, interest in the car also benefits from the broader emotional and historical appeal of the G8 as Pontiac’s swan song — a powerful, rear-wheel-drive sedan that stands in contrast to the brand’s later years before its demise.
Future Outlook
No direct successor to the G8 Firehawk exists; the Pontiac brand was discontinued after 2009 as part of GM’s restructuring, and there are no plans for Pontiac revival in the foreseeable future. However, the architectural legacy of the G8 lives on — notably through the Chevrolet SS sedan produced from 2014 to 2017, which carried forward many mechanical DNA elements of the G8 platform.
Interest in the Firehawk will likely continue to rise among collectors who appreciate low-production, supercharged performance sedans with a connection to classic muscle. The G8 Firehawk stands as a high-water mark not only for Pontiac performance but also for SLP’s ability to craft specialist vehicles that echo muscle-car heritage in a modern context.
The SLP Pontiac G8 GXP Firehawk remains one of the rarest and most exciting performance cars produced in Pontiac’s final chapter — a modern muscle sedan supercharged into legend by the expertise of SLP Performance Parts. Available only in 2009 and produced in tiny numbers, the Firehawk fused potent supercharged power with enhanced suspension, cosmetic flair, and a storied nameplate that harkened back to SLP’s performance history. Its rarity, power output, and place in American automotive history ensure that it will remain a coveted collectible for years to come, embodying the spirit of performance that defined Pontiac and its enthusiasts to the very end.
