Weight is a crucial factor in the performance of a sports car. For the Mercedes-AMG GT-R, the engineers have opted for an especially intelligent material mix.

Aluminium, magnesium and carbon fibre.

Unveiled in Brooklands on 24 June, the AMG GT R, the new spearhead of the Affalterbach-based sports car and performance brand Mercedes-AMG, employs an especially smart material mix. While the chassis and body are made from a variety of aluminium alloys, the boot lid is of steel and the front deck of magnesium.

The weight is optimised by numerous elements such as the active aerodynamic profile on the underbody of high-grade carbon fibre.

Combination of high-tech materials.

The high flexural strength and torsional stiffness of the entire structure allows the transmission of extreme longitudinal and transverse forces from powertrain and chassis. This reduces undesired elasticities; the vehicle responds precisely and directly. In recognition of this intelligent combination of high-tech materials, the AMG GT R has now won the Innovation Award at EXPERIENCE COMPOSITES 2016, a new trade fair for fibre composite materials, lightweight design and carbon fibre.

Weighing just 13.9 kilograms, the carbon-fibre torque tube is 40 percent lighter than the already weight-optimised aluminium component in the AMG GT. In addition, a new carbon-fibre tunnel cross replaces three other aluminium components in the GT. This newly designed lightweight structural element has enabled the experts at AMG not only to reduce the weight, but also to significantly increase the torsional stiffness by 7.5 percent.

Tobias Moers, CEO of Mercedes-AMG GmbH: “We have systematically geared the entire structure of the new AMG GT R to performance using our expertise in composite materials.” Especially the use of carbon fibre, a light yet very strong material from the field of motorsport, helps to achieve the challenging goals. Carbon fibre is used as a material for such components as the front wings, the roof and the propeller shaft tube for an exceptionally torsionally stiff connection between engine and transmission.

Deformable composite material.

The lightweight design experts at AMG also opted for an intelligent use of materials for the so-called wheel catch struts, which are made of a composite material. In an accident, these components comply with the intended crash kinematics by guiding the front wheels onto the side members, where they are blocked. The composite struts are around 50 percent lighter than similar steel components, but, unlike carbon fibre, they are deformable.
