Aston Martin completes the GT Racing lineup with the new Vantage GT4 | Taza Khabre

Key findings

  • The new Aston Martin Vantage GT4 completes the racing GT line, closely resembling the Vantage road car.
  • The Vantage GT4’s engine and transmission are like a road car modified for precise handling.
  • Limited chassis modifications to the new Vantage GT4 improve driving dynamics, production continues.


Two months later in 2024 and Aston Martin already on a roll with his new race and sports cars. Having recently introduced the new AMR24 Formula 1 racing car and its new challenger the Vantage GT3, the British carmaker presents a new car that practically completes the GT racing car line-up – the new Aston Martin Vantage GT4.



Aston Martin reveals its latest Vantage GT4 Racer

The Vantage GT4 is the latest installment in Aston Martin’s GT line

  • The Vantage GT4 is based on the Aston Martin Vantage
  • GT4 rules require the sharing of most elements with the road car
  • The Vantage GT4 looks a lot like the Vantage road car
  • Aerodynamic changes include a larger front splitter and a new rear wing


Like the new Vantage GT3, the Vantage GT4 is largely derived from the Aston Martin Vantage. Both GT cars were designed, engineered and built by Aston Martin Racing (AMR), the automaker’s official GT racing partner. AMR has introduced the Vantage in Racing Green, which has recently become Aston Martin’s best-selling color.

Although AMR developed the Vantage GT4 in parallel with the Vantage GT3, strict regulations required minimal modifications to the GT4 program. According to Aston Martin, the GT4 Vantage shares around 80% of the road car’s structural and mechanical architecture. Modifications include a fully custom roll cage that AMR installs on the aluminum chassis before attaching the body. Other than that, most of the Vantage GT4’s body panels are standard, except for the hood, which has several air intakes.


In terms of design, the Vantage GT4 still resembles its road car version. However, AMR used computational fluid dynamics (CFD) to optimize the GT4’s aerodynamic package with the help of Aston Martin’s design department. Aerodynamic modifications were also limited: the Vantage GT4 received only a larger front splitter and a new rear wing. However, the resulting downforce and reduced drag already exceed those of the previous Vantage GT4.

The Vantage GT4 shares an engine and transmission with the road car

Same engine and transmission, but different operations

  • The Vantage G4 retains the 4.0-liter V8 engine and automatic transmission
  • The twin-turbo V8 uses a Bosch Motorsport ECU
  • The eight-speed automatic transmission has been converted to a six-speed paddle shifter
  • The design of the new Vantage has helped improve engine and brake cooling


Meanwhile, the Vantage GT4’s 4.0-liter twin-turbo V8 engine and transmission are derived from the Vantage road car. Essentially a V8 from Mercedes, the engine in the Vantage GT4 features a Bosch Motorsport control unit with custom software developed by AMR. The driver’s stock automatic transmission is now controlled by ZF/AMR Motorsport software, which converts it from an eight-speed transmission to a six-speed manual transmission without an automatic mode.

Electronic systems modified by AMR provide precise control of the engine management and turbocharger systems, allowing the Vantage GT4 to meet the strict performance balance criteria set by the organizers of the GT4 Championship. In addition, AMR has replaced the visual elements of the road car’s instruments with the latest Bosch DDU11 display.

Interestingly, the design of the new Vantage helps to cool the engine and braking system. Its larger radiator opening means more air can pass through the engine’s cooling system, and the brakes also receive more cooling air.

The Vantage GT4 has limited chassis modifications

Most of the chassis elements are the same, but with exceptions

  • The same suspension attachment points, but the connections have been changed
  • The Vantage GT4 rides on the obligatory 18-inch wheel and tire package
  • The GT4 racer has two-way adjustable shock absorbers from KW
  • Production continues, 40 copies are planned by 2024

Limited changes were also made to the chassis. Its internal suspension mounting points are the same as the road cars, with some permitted changes in the suspension rods. The rules allowed this to provide the correct camber range for the race program, while allowing the GT4 race car to properly accommodate the mandatory 18-inch wheels and tire package. The new Vantage GT4 rides on custom forged aluminum wheels to AMR specifications.


However, the new Vantage GT4 is fitted with KW’s new two-way adjustable dampers courtesy of KW’s AMR technical partner. Using driver feedback from the past six years, AMR has created the new Vantage GT4 with a heightened sense of precision and control through its driving dynamics. Nevertheless, the new race car retains the same vital driver comfort features as its predecessors.

Production of the Vantage GT4 is now underway and the car will make its international racing debut in the IMSA Michelin Pilot Challenge at the Rolex 24 Hours of Daytona in January. AMR is currently building over 40 examples of the Vantage GT4 for the 2024 season. Meanwhile, the new Vantage will arrive in the second quarter of 2024.
