For me I have the same wish as I've had since they removed the DC charging option, faster charging. I'm very happy that they updated the charge tank, but I've done some calculations and in my opinion it's still not possible to go for longer trips with a Zero. 11kW or faster AC accepting 3-phase Mennekes in Europe would work, DC would be best. That way you could drive for a couple of hours, charge about an hour and drive another 1-1.5 hours. 2 hours charging from ~10% - ~90% is still too long to wait in my opinion. Because of the relatively slow charging you're still fairly limited to driving about 50% of the range and turn back so you don't run out of battery.
An aerodynamic option/frame would be nice also.
May I sway your opinion a little Hansi?
I agree with you if you are talking about the kind of touring that includes long stretches of motorway and fast roads. However, if you prefer taking the shorter and more twisty routes, I've found that it is rather difficult to cover much more than about 35 miles per hour. I know this because it's the type of riding I do for pleasure on my 2014DS. It has a range of 65 miles with that kind of riding and I'll regularly get the best part of two hours in the saddle. I think it's fair to say I could get another 30 miles of range from a 2018 SR, so shall we say two and a half hours of riding? Probably more if taking it easy.
If I ever get chance to go touring, I think a day like this could be rather civilised:
10am Get on the bike after a nice lie in and a full English.
11:30am Stop for a cup of tea and a charge if possible.
12:00pm Continue journey
1pm Stop for lunch and charge.
2-3pm Continue journey with a full charge (or at least 90%)
6pm Reach destination (having stopped for another break since lunch somewhere).
That's about 5-6 hours of riding a day covering about 210 miles or so. Probably more like 250 miles with a few faster sections thrown in and getting a little more juice during a tea break.
I know it's not like jumping on a GS and covering 350 miles a day, but I think it would be a lot of fun and not too tiring.
