The SRT Tomahawk Vision Gran Turismo is a series of concept cars by SRT/Dodge as part of the Vision Gran Turismo program that appears in Gran Turismo 6 (as part of Update 1.20) and Gran Turismo Sport. The Tomahawk cars are noted for their high performance and speeds (even exceeding the Red Bull X series cars), with later models specifically designed to require G-suits.
All Tomahawk cars feature the following description in the beginning, followed by trim-specific notes; see each version's page for each trim-specific description.
The SRT Tomahawk Vision Gran Turismo is a 20-year-forward vision of uncompromising, unrestricted performance. It is the virtual fusion of extreme motoring and stunning design. The Tomahawk is a single seat MR-AWD (mid-rear engine, all-wheel-drive) vehicle constructed on a purpose-built composite chassis and designed around an aggressive powertrain.
The motivation for the Tomahawk is provided from two sources:
- The main power plant is a nearly flat, 144-degree 6.98-litre V10 engine generating in excess of 1,000 horsepower.
- Auxiliary power is stored in two composite pneumatic cylinders that run nearly the length of the wheelbase. Each of the front wheels is connected to a Variable-Fin Quad-Stage Pneumatic Power Unit that can rapidly store and release pneumatic energy. A similar Pneumatic Power Unit is connected to the V10 engine. This system provides the Tomahawk with All-Wheel-Drive capability to improve cornering and acceleration when grip at the rear wheels is traction limited.
The Tomahawk's lightweight composite chassis uses emerging advanced materials including hollow carbon nanofibers and graphene micro-lattice structures. All of the transparent elements of the Tomahawk are made from graphene skins including the cockpit and the engine-cover windows. The graphene windscreen allows a clear digital overlay of all vehicle instrumentation and communications in front of the driver as needed. The filament-wound pneumatic cylinders are integral structural elements laminated into the chassis. The entire vehicle design, from the low driver position to the nearly flat layout of the V10 engine, is intended to achieve the lowest possible center of gravity.
The handling dynamics of the Tomahawk are enhanced by a continuously active aerodynamic system which deploys multiple pneumatically driven elements, including a rear wing and a secondary front splitter. These aero panels are constantly adjusting to the track conditions and driver inputs in order to provide the highest level of downforce and the lowest levels of drag when required. The Tomahawk's aerodynamic system reacts to inputs provided by a forward scanning laser system that detects surface changes in front of the car. The computer controls anticipate changes in vehicle ride height, pitch and yaw and adjust the splitter accordingly.
The exhaust of the V10 engine is routed to the rear diffuser in a series of paired runners. Flow from the exhaust works in conjunction with the active aerodynamic system to provide an acceleration of underbody flow at the rear of the car and create a blown diffuser effect that increases downforce with no negative effect on drag.
The Tomahawk suspension also uses the pneumatic system in several ways: The vehicle rides on a set of variable-rate pneumatic springs which also provide adjustable jounce and rebound damping. In addition, the Tomahawk includes a revolutionary active camber system in which the wheel knuckles adjust to lean the vehicle into the turns with each wheel angling outboard or inboard to maintain the optimum tire contact patch and the highest possible mechanical grip.

- In Gran Turismo 6, each Tomahawk car has it's own matching driver suit (including the necessary G-suits for the GTS-R and X), available from GT Auto and from the car's launch Seasonal Event. However, the g-suit required for both models are completely absent in GT Sport for unknown reasons, therefore defaulting to the driver's regular suit. Unusually, however, driving either the Honda Project 2&4 powered by RC213V or Jaguar Vision Gran Turismo Coupé, which made their debuts in GT Sport, will cause the driver to wear a unique racing suit.
- Because the required g-suit for the GTS-R and X are absent from GT Sport and that the driver uses their default racing suit instead, realistically speaking, driving the car would place an enormous amount of stress and trauma on the driver due to the sudden and extremely violent g-forces when accelerating, cornering and braking from high speeds, to the point where braking from maximum speed all the way to a standstill can lead to the driver passing out, or that it can even potentially kill the driver.
- In Gran Turismo Sport's Brand Central, as well in some other screens such as the garage and a offline race's post-race screen, the Tomahawk cars (except the Gr.1 version) are referred by alternate names, with the S designated as "Street", GTS-R as "Racing", and X as "Technology". Coincidentally, these names form the full acronym of the company, "Street and Racing Technology".
- In the Gran Turismo games, the vehicles' production year (except for the Gr.1 version) is tagged as 2035.
- While the interior of the cars in GT6 is shown as a dark silhouette, a fully detailed interior for this car was later added in GT Sport. With all three Tomahawks counted together, it makes it one of only four Vision Gran Turismo cars from GT6 to receive fully detailed interiors, the others being the Nissan CONCEPT 2020 Vision Gran Turismo, the Mazda LM55 Vision Gran Turismo and the Toyota FT-1 Vision Gran Turismo.
- All Tomahawk models share the same interior.
- When the cars' default color/livery is removed upon answering the relevant prompt in Livery Editor, the cars will revert to a metallic version of the Carbon Prototype color, used in the Tomahawk X, unless if the car used in that mode is the Tomahawk X in the Carbon Prototype color.
- In Gran Turismo Sport, players were originally unable to manually activate the active aerodynamics system or to use the pneumatic boost system. This was remedied in Update 1.36, which introduced an overtake button, originally for Dallara SF19 Super Formula '19 which was added in that version.
- Dodge previously produced an unrelated vehicle called Dodge Tomahawk, a V10-powered motorcycle powered by a Viper's engine, capable of extreme speeds, but was never tested.
- Except in Gr.1 version, where the all-wheel drive capability and the auxiliary pneumatic power unit is disabled.
- For the Gr.1 version, these active aerodynamics are all discarded in favor of a fixed rear wing and a LMP-style shark fin; the power output is also reduced to help with the handling. Additionally, the Tomahawk S does not appear to have any form of active aerodynamics.
