@MollsMummy, have a look at the Tesla P90DL, I don't think there's a production Merc that can beat it 0-60mph  (2.8sec 0-60mph and still does >250mpg driven normally....)

Is it type approved for a towbar?

Yes I believe it is - as is the Model X as per here

Don't think the range would be very good tho so not really practical as a towcar.  Potentially EVs would make great towcars as they have max torque instantantly.
