However, as part of the overhaul, the drivers had asked that there be less focus on this in order that they might be able to race more freely without fear of having to manage the tyres throughout the course of a race.ĭriving well below the actual potential of the car became a common theme over the course of the last few years, in order that the tyre didn’t overheat and result in an extra pitstop than was originally planned.Īll of these face a significant reset in terms of their design going into 2022, not forgetting that the aerodynamic balance of the car will also vary, given the shift to a more underfloor biased design. Pirelli has long been at the mercy of the sport in order to increase the entertainment aspect, with thermal degradation identified as a way of creating strategic differences between the teams and drivers. 1, 73760 Ostfildern-Scharnhausen, Germany ( aerodynamicists will also find themselves challenged by the changes, as the lower profile tyre will behave differently to the outgoing rubber - with the dynamic behaviour of the tyre creating inconsistencies that they'll be keen to get a handle on.Ī number of aerodynamic tricks have been used in the sport’s recent past to try and mitigate the effect known as ‘tyre squirt’. But, with many of those design features either removed or heavily constrained, teams will have to find new ways to deal with the resultant change in the tyre’s stiffness and sidewall height. Additional equipment and accessories (attachment parts, tire size, etc.) can change relevant vehicle parameters, such as weight, rolling resistance and aerodynamics and, like weather and traffic conditions as well as individual driving style, influence a vehicle’s electric power consumption, CO₂ emissions and performance figures.įurther information on official fuel consumption figures and the official specific CO₂ emissions of new passenger cars can be found in the “Guide on the fuel economy, CO₂ emissions and power consumption of all new passenger car models,” which is available free of charge at all sales dealerships and from DAT Deutsche Automobil Treuhand GmbH, Hellmuth-Hirth-Str. They are provided only for the purpose of comparison between the various vehicle types. If NEDC values are indicated as a range, they do not refer to one, specific vehicle and are not an integral element of the offer. WLTP values can be provided voluntarily until their use becomes mandatory. In the case of new vehicles for which type approval was performed using WLTP, the NEDC values are derived from the WLTP values. ![]() Additional information about the differences between WLTP and NEDC is available at At the moment, it is still mandatory to communicate the NEDC values. ![]() Due to the more realistic test conditions, the consumption and CO₂ emission values measured are in many cases higher than the values measured according to the NEDC. Since September 1, 2018, the WLTP has gradually replaced the New European Driving Cycle (NEDC). Since September 1, 2017, type approval for certain new vehicles has been performed in accordance with the Worldwide Harmonized Light Vehicles Test Procedure (WLTP), a more realistic test procedure for measuring fuel consumption and CO₂ emissions. ![]() ![]() * The indicated consumption and emissions values were determined according to the legally specified measuring methods.
