Although the new M5 is built off today’s 5-series, known as G30, it gets its own model designation called F90. That’s substantially more than the standard model of yore (560hp and 680Nm) but essentially the same as the 30 Jahre M5 (600hp and 700Nm). As a result, the F90 goes from 0-100kph in 3.4sec, half-a-second quicker than the 30 Jahre M5 and a full second faster than in the regular forebear. But thanks to an additional forward ratio, Mercedes has apparently managed to make the E63 S more frugal on fuel. In pure statistical terms, the E63 S still seems to hold the upper hand despite being developed earlier.
