I am driving a S60 RWD. Back then there was no AWD and P85 was already top of the class
Charging to 90% gives around 276 km of range. You won't use up that amount in Hong Kong in a single day (unless you are working with Uber)
As you may have read from somewhere else on this forum, you don't want the charge to go below 30% (to "protect" the battery and help it "lives" longer), 30% charged is around 90 km
So if you don't have home charger like me, you have a total of 184 km range in between each charge (of course you can drive all the way and charge at 0%, that gives you 276 km). Mind you the current S60 is in fact a S75 with software limited to 60 kWh, so the 90% charged range may be a bit more than 276 km in the "new" S60
I talked to a Tesla staff before, he told me AWD is more efficient in places where you don't have to stop often. In Hong Kong, we are driving in stop-and-go traffic for "long" enough period every day, so he believes RWD is more efficient (gives more real life range for same amount of energy) and also cheaper
Few questions to answer before placing your order:
- Do you have home charger? [No I assume]
- How many km you do per day? [I drive 120 km max during weekends, and with a S60, I don't have to charge more than twice per week]
- Do you feel comfortable waiting at supercharger or do you have chance to use other slower type charger (i.e. availability close to your home or office)? [If no, get a 90D. An owner told me he has around 400 km at 90% charged]
If you don't do too many miles (or km) per week, and you are willing to wait for supercharging or have slower charger available near your home or office, the current S60 will manage your need.
In fact destination charger (Tesla Wall Connector) and IEC 62196 are getting more common in hotels and shopping malls in HK, I manage to charge only once or not at all at supercharger nowadays by using these.
Superchargers are nice, cutting edge technology, but technology can't beat selfishness, there are more than enough Tesla owners parking their cars at supercharger slots in Hong Kong (staying for more than 2 hours). Although you will have to rely on supercharger, you should also plan something else (no matter you will be driving S60 or 90D)
