Hankook conducted testing at Papenburg in Germany and IDIADA near Barcelona for lane-change and general handling, used Nard\u00f2 in southern Italy for high-speed dry testing, and focused on wet handling characteristics at Pferdsfeld and other tracks.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"2560\" height=\"1707\" src=\"https:\/\/reifenlab.eu\/mag\/wp-content\/uploads\/2026\/07\/hankook-ventus-s1-evo-z-porsche-911-tyres-scaled.jpg\" alt=\"Hankook Ventus S1 evo Z tyres for the Porsche 911 Carrera at a test track\" class=\"wp-image-6887\" srcset=\"https:\/\/www.thetirelab.com\/mag\/wp-content\/uploads\/2026\/07\/hankook-ventus-s1-evo-z-porsche-911-tyres-scaled.jpg 2560w, https:\/\/www.thetirelab.com\/mag\/wp-content\/uploads\/2026\/07\/hankook-ventus-s1-evo-z-porsche-911-tyres-300x200.jpg 300w, https:\/\/www.thetirelab.com\/mag\/wp-content\/uploads\/2026\/07\/hankook-ventus-s1-evo-z-porsche-911-tyres-1024x683.jpg 1024w, https:\/\/www.thetirelab.com\/mag\/wp-content\/uploads\/2026\/07\/hankook-ventus-s1-evo-z-porsche-911-tyres-768x512.jpg 768w, https:\/\/www.thetirelab.com\/mag\/wp-content\/uploads\/2026\/07\/hankook-ventus-s1-evo-z-porsche-911-tyres-1536x1024.jpg 1536w, https:\/\/www.thetirelab.com\/mag\/wp-content\/uploads\/2026\/07\/hankook-ventus-s1-evo-z-porsche-911-tyres-2048x1365.jpg 2048w\" sizes=\"auto, (max-width: 2560px) 100vw, 2560px\" \/><figcaption class=\"wp-element-caption\">Photo: Hankook<\/figcaption><\/figure>\n\n\n\n<p>Test driver Aleix Alcaraz said the project had to balance track performance with everyday usability. Hankook also worked with Porsche on vehicle-dynamics tuning over several years. The announcement follows roughly a decade of Hankook supplying original-equipment tyres to Porsche and extends the brand\u2019s presence among performance-car fitments. It also comes alongside other recent OE work, including a <a href=\"https:\/\/reifenlab.eu\/mag\/hankook-ventus-evo-suv-gains-oe-approval-for-vw-tayron-expanding-tiguan-fitment\/\" target=\"_blank\" rel=\"noopener\">Ventus evo SUV fitment for the Volkswagen Tayron<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_the_NA2_marking_means_for_owners\"><\/span>What the NA2 marking means for owners<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>For drivers, the relevant detail is the NA2 sidewall code: it identifies the version developed and approved for this Porsche application. That vehicle-specific tuning is the main consumer value of an OE-homologated tyre in this case. Owners replacing the factory tyres should therefore check the full size and approval marking rather than assuming every Ventus S1 evo Z in a matching nominal size has the same specification.<\/p>\n\n\n\n<p>Hankook has not disclosed pricing or named individual markets in the release. The announcement concerns factory fitment on the Porsche 911 Carrera; it does not state that the NA2 versions will be offered for every 911 derivative or wheel package.<\/p>\n\n","protected":false},"excerpt":{"rendered":"<p>Hankook\u2019s Ventus S1 evo Z is now an original-equipment tyre for the Porsche 911 Carrera, marking the first time a series-production 911 Carrera leaves the factory on Hankook tyres.
