I have had my 50 Technik (with some add-ons) a month now and (ignoring the delivery GOM) had GOM readings of around 150 miles (which I was expecting). I was quoted at the very start that with the additions my WLTP range would be 189 miles, which I never thought I would get...until today.
This week we enjoyed a few days up in Liverpool (approx 145 miles away) and the journey back today must have been optimum conditions for my 'small' battery:
Travelled 142.8 miles. GOM remaining: 51. Total therefore: 193.8.
26% battery remaining too, so based on that 51/0.26 = Approx 196 miles.
Needless to say, I'm pleased with that (but yes, not expecting it all year round
LOL). Absolutely enjoying the driving
