POSAIDON: Power upgrades for the C63 AMG and AMG GT<\/p>\n
Recent highlights for performance car enthusiasts have been AMG\u2019s second sports car, the AMG GT and its GT S variant, quickly followed by the W205 C63 in standard and S forms.<\/p>\n
Both vehicles are powered by a version of AMG\u2019s new 4.0-liter twin-turbo V8 engine, differentiated by the nature of their lubrication. The M178 version in the AMG GT has dry sump lubrication, while the M177 that powers the C63 AMG uses a conventional wet sump system.<\/p>\n
POSAIDON is one of the first tuners to offer power upgrades for AMG\u2019s new performance stars. Significantly, this has been achieved through direct re-programming of the original engine control unit with no additional external boxes.<\/p>\n
In standard trim, the AMG GT has 462 hp and 600 Nm of torque, while the more powerful S version has 510 hp and 650 Nm. The POSAIDON conversion brings either model up to 630 hp with 725 Nm of torque, for a 337 km\/h top speed.<\/p>\n
Out of the box, the C63 AMG has 476 hp and 650 Nm of torque, with 510hp and 700Nm in S form. The POSAIDON ECU remap takes this to a rousing 610 hp with 800 Nm of torque, which rockets the flagship C-Class to 328km\/h. <\/p>\n
The lower peak torque figure quoted for the POSAIDON-tuned AMG GT compared to their C63 AMG is down to the different gearboxes. The AMG SPEEDSHIFT DCT 7G dual-clutch transmission in the AMG GT\/GT S has a lower torque capacity, so POSAIDON limits the maximum twist to 725 Nm. As the AMG SPEEDSHIFT MCT 7-speed sports transmission in the C63\/C63 AMG S will handle up to 1,000 Nm, there is a lot more leeway here.<\/p>\n
While this first tuning step already brings incredible performance to the two newest V8-powered AMG models, the POSAIDON engineers are working on further upgrade stages for the M177 and M178 engines using modified turbochargers, free-flow exhaust systems and some other hardware changes.<\/p>\n
In standard form, the ECO start-stop function is only disabled in Sport and Sport+ modes. POSAIDON offers the driver the option to switch it off in any mode at the touch of a button.
\nTo maximise driver safety, POSAIDON offers a speed camera warning system for the AMG GT, C63 AMG and other Mercedes-Benz models, that integrates with the factory COMAND Online, or Garmin MAP pilot navigation systems.”

Aftermarket tuner Posaidon has just unveiled its tuning upgrades for both the Mercedes-AMG GT and the new Mercedes-AMG C63 and C63 S. As both cars utilise virtually the same twin-turbocharged 4.0-litre V8 engine, it is little surprise the same upgrades apply for both performance cars. Typically, the Mercedes-AMG GT and AMG GT S models deliver […]<\/p>\n","protected":false},"author":190,"featured_media":121463,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[33438,36119],"tags":[35482,34399],"_links":{"self":[{"href":"https:\/\/gtspirit.com\/wp-json\/wp\/v2\/posts\/121462"}],"collection":[{"href":"https:\/\/gtspirit.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gtspirit.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gtspirit.com\/wp-json\/wp\/v2\/users\/190"}],"replies":[{"embeddable":true,"href":"https:\/\/gtspirit.com\/wp-json\/wp\/v2\/comments?post=121462"}],"version-history":[{"count":0,"href":"https:\/\/gtspirit.com\/wp-json\/wp\/v2\/posts\/121462\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/gtspirit.com\/wp-json\/wp\/v2\/media\/121463"}],"wp:attachment":[{"href":"https:\/\/gtspirit.com\/wp-json\/wp\/v2\/media?parent=121462"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gtspirit.com\/wp-json\/wp\/v2\/categories?post=121462"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gtspirit.com\/wp-json\/wp\/v2\/tags?post=121462"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
