Le g\u00e9ant de Detroit vient d\u2019annoncer un\u00a0<strong>investissement de 888 millions de dollars<\/strong>\u00a0dans son usine de Tonawanda, dans l\u2019\u00c9tat de New York, pour y produire une\u00a0<strong>nouvelle g\u00e9n\u00e9ration de moteurs V8 essence<\/strong>. Une initiative en apparence anachronique, mais parfaitement assum\u00e9e.<\/p>\n<p>Cette somme colossale sera consacr\u00e9e \u00e0 la\u00a0<strong>sixi\u00e8me g\u00e9n\u00e9ration de blocs small-block V8<\/strong>, qui \u00e9quiperont notamment les pick-ups et gros SUV du groupe, des segments o\u00f9 la demande reste forte, notamment en Am\u00e9rique du Nord. Une strat\u00e9gie qui contraste fortement avec la promesse faite par GM de devenir\u00a0<strong>100 % \u00e9lectrique d\u2019ici 2035<\/strong>, mais qui t\u00e9moigne aussi d\u2019un\u00a0<strong>r\u00e9alisme industriel face aux limites actuelles de l\u2019\u00e9lectrification<\/strong>.<\/p>\n<p>Entre contraintes d\u2019infrastructure, prix d\u2019achat \u00e9lev\u00e9s et r\u00e9ticence d\u2019une partie du public,\u00a0<strong>l\u2019\u00e9lectrique ne progresse pas partout au m\u00eame rythme<\/strong>. En maintenant une offre thermique optimis\u00e9e, GM tente de\u00a0<strong>concilier imp\u00e9ratifs \u00e9conomiques et \u00e9volution technologique<\/strong>, sans rompre brutalement avec son socle de client\u00e8le historique.<\/p>\n<p>\u00c0 travers cet investissement, c\u2019est donc\u00a0<strong>une vision plus nuanc\u00e9e de la transition \u00e9nerg\u00e9tique<\/strong>\u00a0qui se dessine : non pas un virage \u00e0 180\u00b0, mais une phase d\u2019adaptation, o\u00f9 thermique et \u00e9lectrique coexistent encore pour quelques ann\u00e9es.<\/p>\n<p>&nbsp;<\/p>\n<figure
