In Montoya\u2019s eyes, Mercedes\u2019 rivals are wrong to complain, stressing that what makes F1 great is the technical ingenuity involved in finding ways to work around the rules.<\/p>\n<p>Asked what he makes of Mercedes&#8217; rivals questioning the legality of its power unit, Montoya exclusively told RacingNews365: &#8220;For me, it\u2019s kind of crazy to say that it\u2019s not in the rules.\u00a0<\/p>\n<p>&#8220;If the rule says [you need to] measure at this temperature and you go and measure at that temperature, and the engine is [deemed] legal, that\u2019s what the rule says.\u00a0<\/p>\n<p>&#8220;That\u2019s the beauty of F1: finding ways to bend the rules, finding ways to do it better than anybody else, and finding things that nobody else can do.\u00a0<\/p>\n<p>&#8220;And if you\u2019re complaining about that, instead of complaining, why don\u2019t you try to do it yourself?&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"Former Formula 1 driver Juan Pablo Montoya has robustly defended the legality of Mercedes\u2019 power unit, at a&hellip;\n","protected":false},"author":2,"featured_media":597788,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[573],"tags":[64,63,827,817,830,828,831,829,826,813,816,823,825,824,822,85],"class_list":{"0":"post-597787","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-formula-1","8":"tag-au","9":"tag-australia","10":"tag-daniel-ricciardo","11":"tag-f1","12":"tag-f1-calendar","13":"tag-f1-live","14":"tag-f1-results","15":"tag-f1-standings","16":"tag-ferrari","17":"tag-formula-1","18":"tag-formula1","19":"tag-lewis-hamilton","20":"tag-max-verstappen","21":"tag-motorsport","22":"tag-racing","23":"tag-sports"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/597787","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=597787"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/597787\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/597788"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=597787"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=597787"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=597787"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
