Toyota's wing mirrors impact performance so much (more grip) on the fast stages of #RallyCER that new ones are reinstalled during tyre fitting zones, forcing teams to carry spares all morning (~500 g extra), even though they can be lost again soon after

The FIA World Motor Sport Council approved today the creation of an RC6 class for Rally6 Group cars - Four-seater, two-wheel drive ICE cars, Standard 1.6T or 2.0 NA engine, power-to-weight ratio of 7.5 kg/hp. No news about WRC27 Regulations. #WRClive #WRCliveES #WRCjp

Tänak will contest CER in the previous spec (Monte-Carlo'25) car (above in the image) with a new engine, while Neuville & Fourmaux will drive the last evolution (Canarias'25) (below) with new damper struts. Note the different front damper angle

Brakes will be under greater stress than ever with the WRC’s return to tarmac. Higher speeds & more grip generate stronger braking forces, producing intense heat that must be dissipated to ensure performance. Here's our review of the Rally2 brake cooling systems

Hyundai’s decision to make Tänak's car ineligible for Manufacturers’ points from Central European Rally means no limits apply in the number of unsealed components - engines, turbos, chassis, subframes, steering racks, shock absorbers & onboard spares

Downforce diminishes from very small angles, as the wing becomes less effective. But with high angles, side force (or the force exerted by air against the sliping rear) plays a role in reducing the tendency to slip, thus helping the driver to control oversteering

The aerodynamics of #Rally1 cars are designed (and wind tunnel tested) to work at maximum angles of 20º. But reality proves that the cars are placed at higher angles in some corners (up to 40º), such as in #RallyChile SS12 yesterday

New protection on the front air intake of today's Toyota GR Yaris #rally1 (top image) at #rallychile compared to yesterday's (bottom image), possibly to better protect the radiators while distributing the air differently

Škoda has also been working this week on the development of the Fabia RS #rally2 , testing a car with a new, bigger roof scoop to improve temperature inside the vehicle, but which could affect the performance of the rear wing due to the increased wake from the enlarged intake.

On the fast stages of #RallyFinland, as in Estonia, it will be critical not to damage the front bumper, splitter or mirrors, as they form the aero package responsible for ensuring downforce (grip) at the front of the car & balance

The front left damage of @OliverSolberg01 & @AdrienFourmaux on @RallyEstonia SS6 might only look cosmetic, but this part is critical for generating front grip, leading to transverse & longitudinal imbalance and make driving hard
