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 1 September 2017 certain new cars have been type approved in accordance with the Worldwide Harmonised Light Vehicles Test Procedure (WLTP), a more realistic test procedure to measure fuel/electricity consumption and CO₂ emissions. As of 1 September 2018 the WLTP replaced the New European Driving Cycle (NEDC). Due to the more realistic test conditions, the fuel/electricity consumption and CO₂ emission values determined in accordance with the WLTP will, in many cases, be higher than those determined in accordance with the NEDC. This may lead to corresponding changes in vehicle taxation from 1 September 2018. You can find more information on the difference between WLTP and NEDC at www.porsche.com/wltp.
Currently, we are still obliged to provide the NEDC values, regardless of the type approval process used. The additional reporting of the WLTP values is voluntary until their obligatory use. As far as new cars (which are type approved in accordance with the WLTP) are concerned, the NEDC values will, therefore, be derived from the WLTP values during the transition period. To the extent that NEDC values are given as ranges, these do not relate to a single, individual car and do not constitute part of the offer. They are intended solely as a means of comparing different types of vehicle. Extra features and accessories (attachments, tyre formats, etc.) can change relevant vehicle parameters such as weight, rolling resistance and aerodynamics and, in addition to weather and traffic conditions, as well as individual handling, can affect the fuel/electricity consumption, CO₂ emissions and performance values of a car.
