Some of the WRC27 Rally1 concepts published today by
FIA seem to propose an intermediate aero package between those of the current Rally1 & Rally2 cars, which should help to differentiate them from Rally2 visually, but also in terms of performance #WRClive #WRCliveES #WRCjp

First images of the Lancia Ypsilon Rally2 HF Integrale testing for Monte-Carlo & first novelty: extended side wing supports to prevent external airflow from entering under the wing, thus pressure is reduced under it, which becomes more effective📹 by @passatsdecanto

No changes to #Rally1 technical regulations in 2026, as published today by @FIA, while minor changes for #Rally2: alternator belt becomes free & only a direct mechanical linkage between steering wheel and steered wheels is permited (also for Rally3/4/5)

Development on tarmac continued this week for the Toyota Yaris GR #rally2 - in the image with Juho Hänninen at the wheel - in some old Rally RACC stages, while the fight for the titles was still on #wrclive #wrclivees #wrcjp

The 2026 #WRC Sporting Regulations, published yesterday, allow engine replacements during a rally (with FIA consent) to all cars except Rally1 Manufacturer entries- to date it was only allowed before TC0. A 60-min penalty will apply & no points scored #WRClive #WRCliveES #WRCjp

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

Detail of the Ford Puma #Rally1 front bumper intake coolers & intakes, ahead of Central European Rally, where an adequate protection will be crucial to prevent the accumulation of leaves that could reduce cooling capacity

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

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

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.

Busy week for Rally2 development: Toyota tests in Greece, Lancia unveils its Rally2 proposal & Citroën tests an evolution of the C3 #Rally2, with a centered exhaust pipe to better remove air from under the car (for more grip)

Completely flat undercar in a event as fast as Rally del Paraguay ensures that air flows faster under the #Rally1 cars, thus reducing pressure under the car and increasing grip

Wing mirror replacement in all Toyota GR Yaris #Rally1 today at
Rally del Paraguay: return to the Safari mirror, less prominent (less air resistance) and more reliable

Different approach on the same jump of @officialrallypy by Toyota rally drivers: nose up (Katsuta), flat (Rovanperä), nose down (Ogier) or tilted sideways (Pajari)

Growing rake - forward inclination of the floor for more front grip - at the start of #WRCinParaguay SD: smaller for the Puma, medium in the i20N & bigger in the Yaris (as usual) & significantly high ride height to avoid damages in an unknown terrain

The open bonnet of the Hyundai of Ott Tanak at #RallyFinland causing drag but even worse, generating lift as air enters under the bonnet instead of pressuring it down, and front grip can be significantly affected #WRClive #WRCliveES #WRCjp

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
