An electric car that is particularly noteworthy for it's use of a two speed transmission, something I'm not sure any other electric car currently has?
The i8 has a two-speed GKN transmission for its front (electric) axle, which was the first modern set-up of its type, and that's been around since '14. Not a pure EV, mind!
a video that resumes the issue - interesting that cvt boxes couldn't yet take the power of many ev motors.
Could Electric Cars Have A Manual Transmission?
A CVT could withstand the torque output of an electric motor if you wanted it to. I remember driving Multitronic (CVT) diesel Audis about ten years ago and those had up to 295lb ft, which is 50-odd more than that produced by the motor in, say, a Nissan Leaf. Okay, that doesn't sound impressive – but CVTs get used in industrial kit, too, so the torque capacity is there if you really wanted it.
Many older electric cars had multi-ratio manual or automatic transmissions but one more modern example (albeit one that didn't make production) is the Detroit Electric SP.01. Your comment on the video just reminded me of it; it was based on an Elise would have had a four-speed manual transmission as standard – although you could reinstate fifth and sixth if you wanted. It was probably the OEM Toyota box, I would have thought, just with the top two ratios locked out by default.
Obviously, in both cases, you have to discount the fact that you don't really need a multi-ratio or continuously variable transmission in most electric car applications.
The demise of the manual gearbox is more due to the driving aids that are slowly becoming mandatory.
Yeah, definitely a big part of it. It's much easier to integrate and enable safety, convenience and emissions-reducing functions with automatic transmissions – and manual gearboxes can be a packaging and assembly faff.
Those are among the reasons that Kia/Hyundai introduced a clutch-by-wire system recently – it basically looks like a manual and drives like a manual, and retains the otherwise typically lighter and cheaper transmission, but it allows for automated engine-off coasting and is less convoluted to design and put together than a standard manual set-up (among other benefits).
