Aston Martin completes the racing lineup of the new Vantage with the debut of the GT4. The new model, developed by the Aston Martin Racing (AMR) division, is an upgraded version of its predecessor, featuring improvements in cooling and aerodynamics alongside a revised chassis setup.
The regulations in the GT4 class mean that the racecar shares 80 percent of the “structural and mechanical architecture” with the roadgoing model. While it doesn’t have the wild looks of the recently introduced GT3-spec version, the Vantage GT4 makes our appetite for a hotter derivative of the road-legal Vantage.
The more aggressive aerodynamic package combines a fixed rear wing with a more prominent front splitter. Those two components are said to offer more downforce but less drag compared to the outgoing Vantage GT4. The only other body component that is not shared with the regular Vantage is the vented hood, made from a sustainable natural flax fiber composite stiffened via a cork core material. Finally, a larger radiator aperture feeds the engine with more air, and tweaked brake ducts improve cooling.

Inside, a custom roll cage is fitted on the bonded aluminum chassis. The dashboard and center console have been replaced by dual displays, carbon-fiber casing, and an array of motorsport switches. We can also see the full racing bucket by Racetech, and the F1-style steering wheel.
Performance And Chassis Setup
Under the hood lies the familiar AMG-sourced twin-turbo 4.0-liter V8 of the Vantage, albeit with a tweaked ECU by Bosch Motorsport. The output can be adjusted but in base form, it has been reduced to 469 hp (350 kW / 476 PS) and 640 Nm (472 lb-ft). The 2025 Aston Martin Vantage road car makes a healthier 656 hp (489 kW / 665 PS) and 800 Nm (590 lb-ft) of torque.
Similarly, the eight-speed automatic transmission received new software from ZF and AMR, effectively turning it into a six-speed paddle-shift gearbox. Besides the omission of the last two overdrive gears, the racing treatment also includes the deletion of the automatic function.
Chassis upgrades are focused on the two-way adjustable KW dampers, alongside a few permitted changes on the suspension linkages allowing a more aggressive camber. Finally the model rides on a new set of 18-inch forged aluminum wheels which are significantly smaller in diameter than the 21-inch wheels of the regular Vantage, as dictated by the GT4 regulations.
The Aston Martin Vantage GT4 quietly made its racing debut at the Rolex 24 Hours at Daytona last month alongside the Vantage GT3. The company plans to build more than 40 units during the 2024 season and has already delivered several units to customer teams.
