A couple of issues came to mind when I heard Elon make that “over 250mph” top speed claim for the new Roadster: 1) I don’t see how that speed can be achieved without at least a 2-speed gearbox (or maybe 3-speed). Roadster fans know that way back in 2008 the Roadster debuted with a 2-speed Borg Warner gearbox but locked in first gear because the the gearbox kept breaking under hard acceleration. That gearbox was replaced with a single speed unit. It appears that Telsa has now solved that problem. 2) The new Roadster will rebut German critics who say that real cars have to be capable of extended periods of 150+mph travel on the Autobahn. The massive battery capacity may have been chosen in part to support that capability. 3) And if the new Roadster can in fact do that then the 3 motors likely have special cooling systems that the S/X/3 lack.
