Turbo Widowmaker
2005 Pontiac G6
The 2005 Pontiac G6 Turbo Widowmaker is a radical reimagination of a mid-2000s sedan into a Time Attack Unlimited contender. With an extreme widebody stance pushing track width over 600mm front and rear, this build embraces aggressive aerodynamics and functional engineering. Every surface is sculpted for maximum downforce and airflow management, from vortex-generating fenders to an active rear wing and integrated diffuser, marrying carbon fiber artistry with race-proven efficiency.
Under the hood, a heavily modified 3.6L V6 twin-scroll turbo setup delivers over 600 horsepower, supported by an advanced cooling system fed through NACA ducts and side vents. The suspension and forged wheel setup are calibrated for razor-sharp cornering, with ultra-wide Toyo Proxes R888R tires gripping every inch of American road courses. This G6 is a technical statement—a forgotten car reborn with purpose and precision.

Platform
2005 Pontiac G6
The 2005 Pontiac G6 sits at the crossroads of mid-2000s American design and mainstream performance, offering a balanced package of style and everyday usability. Built on GM's Epsilon platform, the G6 features a front-engine, front-wheel-drive layout with a focus on clean lines and accessible performance, making it a popular choice for drivers seeking a sporty yet practical sedan or coupe. Its architecture provides a solid, well-engineered foundation that has proven versatile enough for various custom and tuning projects, blending understated design with the potential for spirited driving.
⌘
Aero Package
Multi-element 1600mm wide adjustable rear wing on titanium hydraulic actuators
Active composite carbon rear hatch with integrated upper diffuser fins and aero flap
Floor-hugging side skirts with triple layered vertical fins directing underbody airflow
Front splitter with aerodynamic canards and sharp bumper corners
⟡
Chassis
Purpose-built for American pro racing circuits, the Turbo Widowmaker excels in high-speed corners with its massive tire contact patches and aerodynamic downforce. The active rear wing and diffuser work in concert to balance stability and reduce drag, while the aggressive camber and suspension tuning provide razor-sharp handling, making it a formidable presence on time attack tracks.

Wave 11
Time Attack Everything: Vol. 1
We took time attack culture and cranked it all the way to eleven with these radical mutations that would make any track day warrior drool. From a 1940 Ford turned aerodynamic beast with wings that scream ‘hold on tight’ to a jet fighter-inspired Dodge Challenger Hellcat that’s basically a stealth bomber on wheels, our builds push widebody tech and aero wizardry beyond the usual limits.
