In the followup C140 600 SEC, Mercedes did use a version of the M120 V-12 with close to 400 horses, but the Sledgehammer from Renntech simply demolishes those numbers.<\/p>\n<p>The all-aluminum, hand-built engine produces 660 horsepower and 650 lb-ft of torque, and it features hand-formed equal-length headers for a \u201csignature V-12 sound.\u201d Renntech hasn\u2019t disclosed further technical details on the Sledgehammer\u2019s running gear, stating only that it has a \u201cunified chassis, drivetrain, and aerodynamic package.\u201d<\/p>\n<p>The company\u2019s renders show a wraparound bodykit and wide, box-flared fenders that are all well in keeping with original 1980s styling of the car, along with a hood bulge to accommodate that V-12. Only the rear diffuser looks a little out of context but will, no doubt, help keep the Sledgehammer grounded at speed, along with a small lip spoiler on the trunk lid. Five-spoke deep-dished alloy wheels are custom-forged in a classic AMG style. The interior will be customized to each buyer\u2019s taste.<\/p>\n<p>Renntech describes itself as \u201cthe foremost authority in AMG and Mercedes-Benz performance tuning since 1989\u201d and has recently developed update packages for the AMG GT63 and Black Series, along with a selection of \u201980s and \u201990s restomods. Renntech says it only plans to build 12 Sledgehammers, with the the first due to hit the road in December 2027.<\/p>\n","protected":false},"excerpt":{"rendered":"It\u2019s the turn of the C126-Series Mercedes-Benz SEC to join the restomod ranks\u2014and Florida\u2019s Renntech is ensuring it&hellip;\n","protected":false},"author":2,"featured_media":470217,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[191473,49,48,583,191472,190388,162959,1464,61],"class_list":["post-470216","post","type-post","status-publish","format-standard","has-post-thumbnail","category-technology","tag-c126","tag-ca","tag-canada","tag-mercedes-benz","tag-mercedes-sec","tag-renntech","tag-restomod","tag-sec","tag-technology"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/470216","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=470216"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/470216\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/470217"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=470216"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=470216"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=470216"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
