A material challenge: losing weight to go faster. And, at the same time, ensuring considerable stiffness both in the physical design and in the corners. For these reasons, too, the new 911 GT3 RS is made of an aluminium and steel composite. This keeps the vehicle weight low. And power potential high.
The front end consists of lightweight polyurethane with hollow glass microspheres and carbon-fibre elements. This high-tech material is not only particularly robust, but also – as the name suggests – exceedingly light.
Carbon-fibre reinforced plastic, or CFRP, is used for the contoured front lid, the front wings, the rear lid and, not least, for various interior components.
The roof is made of magnesium and, like the front lid, is purposefully contoured. Not only does this contouring visually distinguish these lightweight components, it also increases their stiffness.
The rear screen and rear side windows are made of lightweight glass. This material is as light as polycarbonate and, unlike polycarbonate, offers particularly good scratch and fracture resistance as well as being significantly less prone to buckling at high speeds.
If you do mean business on the race track, you could even dispense with the sound system or two-zone automatic climate control on request.
In total, all these weight-reduction measures add up to a weight-to-power ratio of only 3.73 kg/kW (2.75 kg/hp). A value that not only looks good on paper, but is also quantifiable by the seconds saved on the race track.

* Data determined in accordance with the measurement method required by law. Since 01 September 2018 all new cars are approved in accordance with the Worldwide Harmonized Light Vehicles Test Procedure (WLTP). You can find more information on WLTP at www.porsche.com/wltp. From 01 January 2019, all fuel consumption figures are shown as determined in accordance with WLTP. CO₂ figures will be shown as NEDC-equivalent values, as CO₂ based taxation will continue to be based on an NEDC value (derived from WLTP) until 06 April 2020. For Plug-in Hybrid Electric Vehicle (PHEV) range and Equivalent All Electric Range (EAER) figures are determined with the battery fully charged, using a combination of both battery power and fuel.
Values are provided for comparison only. To the extent that fuel and energy consumption or CO₂ values are given as ranges, these do not relate to a single, individual car and do not constitute part of the offer. Optional features and accessories can change relevant vehicle parameters such as weight, rolling resistance and aerodynamics which may result in a change in fuel or energy consumption and CO₂ values. Vehicle loading, topography, weather and traffic conditions, as well as individual driving styles, can all affect the actual fuel consumption, energy consumption, electrical range, and CO₂ emissions of a car.
