Para a Porsche Penske Motorsport foi a terceira vit\u00f3ria seguida na corrida que abre todos os anos a temporada da <strong>IMSA<\/strong>.<\/p>\n<p>Para muitos leitores europeus a sigla diz pouco. A resposta curta \u00e9 que a IMSA \u00e9 a entidade que organiza o campeonato em que os fabricantes se enfrentam com prot\u00f3tipos e GT nos circuitos da Am\u00e9rica do Norte. A resposta longa explica porque \u00e9 que, para uma marca que olha para os Estados Unidos, vale a pena conhec\u00ea-lo.<\/p>\n<p><strong>Em resumo<\/strong><\/p>\n<ul>\n<li>A <strong>International Motor Sports Association<\/strong> nasce em 1969 e organiza hoje o <strong>IMSA WeatherTech SportsCar Championship<\/strong>, o principal campeonato norte-americano de prot\u00f3tipos e GT.<\/li>\n<li>As classes s\u00e3o quatro: <strong>GTP<\/strong>, LMP2, GTD PRO e GTD, que nas corridas de resist\u00eancia correm todas juntas.<\/li>\n<li>Em 2026 o t\u00edtulo GTP foi para <strong>Jack Aitken<\/strong> com o Cadillac n\u00famero 31 da Action Express Racing.<\/li>\n<\/ul>\n<h2>O que \u00e9 a IMSA<\/h2>\n<p>IMSA \u00e9 o acr\u00f3nimo de International Motor Sports Association, a entidade com sede em Daytona Beach, na Florida, que redige os regulamentos e organiza as principais corridas de carros de sport da Am\u00e9rica do Norte. O seu campeonato principal chama-se IMSA WeatherTech SportsCar Championship: uma temporada que vai de janeiro a outubro e alterna corridas de resist\u00eancia, como as 24 Horas de Daytona e as 12 Horas de Sebring, com corridas mais curtas em circuitos citadinos e permanentes.<\/p>\n<p>O que surpreende quem o v\u00ea pela primeira vez \u00e9 a conviv\u00eancia em pista de carros muito diferentes. Os prot\u00f3tipos h\u00edbridos das marcas correm ao lado de GT derivados de modelos de s\u00e9rie, com classifica\u00e7\u00f5es separadas e a mesma linha de meta. Cada ultrapassagem entre uma classe e outra \u00e9 um pequeno problema a resolver, e numa corrida de vinte e quatro horas h\u00e1 muit\u00edssimas.<\/p>\n<h2>De 1969 ao campeonato \u00fanico<\/h2>\n<p>A IMSA nasce em 1969 por iniciativa de John Bishop, antigo dirigente do Sports Car Club of America, e da mulher, Peggy, com o apoio de Bill France Sr., o fundador da NASCAR. Nos anos 70 o seu campeonato GT alarga-se \u00e0s corridas de resist\u00eancia e, a partir de 1973, inclui tamb\u00e9m as 12 Horas de Sebring.<\/p>\n<p>Durante muitos anos os carros de sport americanos dividem-se entre duas s\u00e9ries: a Grand-Am, ligada ao mundo da NASCAR, e a American Le Mans Series, fundada em 1999 por Don Panoz com base no regulamento do ACO, a entidade que organiza as 24 Horas de Le Mans. Em setembro de 2012 Panoz cede a sua s\u00e9rie \u00e0 Grand-Am e \u00e9 anunciada a fus\u00e3o; em 2013 o novo campeonato recebe nome e patrocinador principal, e a 25 e 26 de janeiro de 2014, em Daytona, estreia-se o Tudor United SportsCar Championship. Desde 2016 tem o nome atual, com a WeatherTech como patrocinador principal: um acordo nascido para dez anos e j\u00e1 prolongado at\u00e9 2030.<\/p>\n<h2>As classes da IMSA: GTP, LMP2, GTD PRO e GTD<\/h2>\n<p>A classe rainha \u00e9 a <strong>GTP<\/strong> (Grand Touring Prototype), criada em 2023 com os prot\u00f3tipos h\u00edbridos do regulamento LMDh: o chassis vem de um dos quatro construtores LMP2 autorizados, o sistema h\u00edbrido \u00e9 igual para todos e o motor e a carro\u00e7aria s\u00e3o da marca. Em 2026 correram onze carros de cinco marcas: Acura ARX-06, BMW M Hybrid V8, Cadillac V-Series.R, Porsche 963 e Aston Martin Valkyrie, este \u00faltimo constru\u00eddo segundo as regras Hypercar do Mundial de Resist\u00eancia. A Cadillac, a BMW e a Aston Martin correm com os mesmos carros tamb\u00e9m no <a href=\"https:\/\/rtrsports.com\/pt-pt\/patrocinio-do-campeonato-do-mundo-de-endurance-wec-da-fia\/\">Mundial de Resist\u00eancia (WEC)<\/a>, e a possibilidade de usar o mesmo carro em dois campeonatos \u00e9 um dos motivos que trouxeram os fabricantes para esta classe.<\/p>\n<p>A <strong>LMP2<\/strong> \u00e9 a classe dos prot\u00f3tipos mais simples, hoje na pr\u00e1tica todos ORECA 07 com motor Gibson, onde profissionais correm ao lado de pilotos n\u00e3o profissionais: o t\u00edtulo de 2026 foi para Alex Quinn e George Kurtz, cofundador e presidente executivo da CrowdStrike, com o ORECA n\u00famero 04 da equipa CrowdStrike by APR.<\/p>\n<p>As duas classes GT usam os mesmos carros, constru\u00eddos segundo o regulamento FIA GT3. Na <strong>GTD PRO<\/strong> correm tripula\u00e7\u00f5es de profissionais; na <strong>GTD<\/strong> as tripula\u00e7\u00f5es s\u00e3o mistas, com pilotos profissionais e n\u00e3o profissionais. Em 2026 a GTD PRO foi ganha por Neil Verhagen e Connor De Phillippi com o BMW M4 GT3 EVO n\u00famero 1 da Paul Miller Racing, e a GTD por Russell Ward e Philip Ellis com o Mercedes-AMG da Winward Racing, no seu terceiro t\u00edtulo consecutivo.<\/p>\n<h2>As corridas que contam<\/h2>\n<p>Quatro provas fazem a hist\u00f3ria do campeonato. As <strong>Rolex 24 At Daytona<\/strong>, no fim de janeiro, s\u00e3o a corrida de abertura e a mais famosa, disputada em parte na oval do Daytona International Speedway. As <strong>12 Horas de Sebring<\/strong>, em mar\u00e7o, correm-se na Florida num antigo aer\u00f3dromo militar, com um piso irregular que faz parte da sua fama. As <strong>6 Horas de Watkins Glen<\/strong>, no estado de Nova Iorque, disputam-se num dos circuitos com mais hist\u00f3ria dos Estados Unidos. O <strong>Petit Le Mans<\/strong>, em Road Atlanta, fecha a temporada no in\u00edcio de outubro: em 2026 correu-se a 3 de outubro e foi ganho pelo Porsche n\u00famero 6 de Laurens Vanthoor, Kevin Estre e Matt Campbell, \u00e0 frente do BMW por pouco mais de um segundo.<\/p>\n<p>Basta olhar para os nomes oficiais para perceber boa parte do modelo comercial: Rolex 24 At Daytona, Mobil 1 Twelve Hours of Sebring, Sahlen&#8217;s Six Hours of The Glen, Motul Petit Le Mans. Cada grande corrida tem uma marca no t\u00edtulo, tal como o pr\u00f3prio campeonato.<\/p>\n<h2>O 2026 da IMSA<\/h2>\n<p>A temporada de 2026 foi da Cadillac. Jack Aitken venceu o t\u00edtulo de pilotos GTP com o Cadillac n\u00famero 31 da Action Express Racing, que partilhou com Earl Bamber e Frederik Vesti; a equipa venceu o t\u00edtulo de equipas e a Cadillac o de construtores, o quinto na classe rainha desde 2017. A Porsche Penske Motorsport abriu e fechou o ano com vit\u00f3rias em Daytona e no Petit Le Mans.<\/p>\n<p>Foi tamb\u00e9m, pelo menos para j\u00e1, a \u00faltima temporada da Acura na GTP: a marca p\u00f4s em pausa no final de 2026 o programa com a Meyer Shank Racing para concentrar o seu esfor\u00e7o na IndyCar. Para 2027 a BMW, a Cadillac e a Porsche confirmaram a presen\u00e7a e os construtores na GTP dever\u00e3o ser quatro; segundo a imprensa especializada, a Genesis, a Ford e a McLaren n\u00e3o entrar\u00e3o, se alguma vez entrarem, antes de 2028.<\/p>\n<h2>O que a IMSA oferece a uma empresa<\/h2>\n<p>O primeiro dado \u00e9 o mercado. A IMSA \u00e9 a principal porta de entrada nos Estados Unidos para quem trabalha com a resist\u00eancia, e o seu p\u00fablico tamb\u00e9m se alcan\u00e7a pela televis\u00e3o: para 2026 a NBC Sports programou mais de 160 horas em direto entre NBC, Peacock e NBCSN, corridas e qualifica\u00e7\u00f5es inclu\u00eddas.<\/p>\n<p>O segundo \u00e9 a variedade. Um campeonato com quatro classes, da GTP das marcas oficiais \u00e0 GTD das equipas privadas, oferece n\u00edveis de entrada muito diferentes, e as marcas que o perceberam s\u00e3o de todos os tipos: da tecnologia, como a CrowdStrike, aos lubrificantes, dos rel\u00f3gios aos acess\u00f3rios para autom\u00f3veis. A f\u00f3rmula dos nomes, do campeonato a cada corrida, mostra at\u00e9 que ponto a IMSA pensa como uma propriedade comercial antes mesmo de pensar como entidade desportiva. A Michelin, fornecedor \u00fanico de pneus, renovou o seu acordo em outubro de 2025.<\/p>\n<p>Na nossa opini\u00e3o, o valor para uma empresa europeia est\u00e1 sobretudo na liga\u00e7\u00e3o ao resto do desporto motorizado. V\u00e1rios carros GTP, e muitas vezes os mesmos pilotos, encontram-se no WEC e nas <a href=\"https:\/\/rtrsports.com\/pt-pt\/blog\/patrocinio-nas-24-horas-de-le-mans-o-que-uma-marca-pode-comprar-e-o-que-ganha-com-isso\/\">24 Horas de Le Mans<\/a>, pelo que um projeto constru\u00eddo na IMSA pode continuar na Europa, e vice-versa. Quem estuda os Estados Unidos tem ainda outros caminhos, da <a href=\"https:\/\/rtrsports.com\/pt-pt\/agencia-de-patrocinio-da-indycar\/\">IndyCar<\/a> \u00e0 <a href=\"https:\/\/rtrsports.com\/pt-pt\/agencia-de-patrocinio-nascar\/\">NASCAR<\/a>, com p\u00fablicos e custos muito diferentes: a escolha depende de quem se quer alcan\u00e7ar, n\u00e3o da fama da s\u00e9rie. Para quem parte da Europa, \u00e9 tamb\u00e9m \u00fatil o nosso guia sobre <a href=\"https:\/\/rtrsports.com\/pt-pt\/blog\/o-wec-e-o-mesmo-que-le-mans\/\">o que distingue o WEC das 24 Horas de Le Mans<\/a>.<\/p>\n    <div itemscope itemtype=\"https:\/\/schema.org\/FAQPage\" class=\"faq-schema-wrapper question-list-wrap\">\r\n\r\n                    <h2><b>Perguntas frequentes sobre a IMSA<\/b><\/h2>\r\n        \r\n        <br \/>\n    <div itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\" class=\"faq-item question-list-row\">\r\n\r\n        <h3 class=\"h5\" itemprop=\"name\">\r\n            <b>O que \u00e9 a IMSA?<\/b>\r\n        <\/h3>\r\n\r\n        <div itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\r\n            <div itemprop=\"text\" class=\"question-answer\">\r\n                <p>A IMSA (International Motor Sports Association) \u00e9 a entidade com sede em Daytona Beach, na Florida, que organiza as principais corridas de carros de sport da Am\u00e9rica do Norte.
