Zero's recommended tension range is 25 kg to 76.5 kg
Are you sure? I think it is 20-30kg. 70kg is far too much.

Here is what the 2018 Zero manual says:

1. Remove the key from the ignition switch.
2. Press the Tension Tester steadily to the non-cogged
side of the belt, half of the distance between the
motor-driven sprocket and rear wheel drive sprocket.
The “lip” of the tester will lead the tester on to the belt.
3. Slowly increase the pressure on the tester, until you
hear a clicking sound. Do not increase the pressure
after the tester has clicked.
4. Remove the tester carefully from the belt. Avoid rough
movements of the tester, as this would change the
results of the measurement.
5. Adjust drive belt tension if the measurement is outside
the recommended range.
Belt Pitch Recommended Tension Range
11 mm 25 kg to 76.5 kg

Wow, that's a huge difference to the 2016 model:

 Remove the key from the ignition switch.
2.  Press the Tension Tester steadily to the non-cogged
side of the belt, half of the distance between the
motor-driven sprocket and rear wheel drive sprocket.
The “lip” of the tester will lead the tester on to the belt.
3.  Slowly increase the pressure on the tester, until you
hear a clicking sound. Do not increase the pressure
after the tester has clicked.
4.  Remove the tester carefully from the belt. Avoid rough
movements of the tester, as this would change the
results of the measurement. The measurement should
be in the range of 20-30 kg.

Probably the newer, wider belt on the 2017+ models...

I went for a ride today and didn't see any difference in range over the 10-mile ride that I take every week.  The 10 miles of suburban and expressway streets took 6% of the battery capacity - according to the display.  That is the same as my 2014 Zero S when it was new.  After almost 4 years and 350 charges, the 2014 Zero was doing the same trip using 10%, but that is starting out at a 98% charge - as far as it would charge, so probably an 8% pack usage.

I learned today from a freeway ride that the Zero "Touring Windshield" has a moveable deflector mounted to the top of the shield.  It works great at smoothing the air flow over my helmet when in its lowest position, but raising it to its highest position resulted in much more noise and buffeting.  I might add that I posted photos of my new bike on a BMW forum and that windshield's looks really got dumped on - especially by Italians.  ::)

When I returned home I was thinking that my belt might be too tight. So I checked it while it was still warm and discovered that I had misread the tension tester scale yesterday.  I was reading the pound scale and not the kilogram scale.  :-[ The tension was set at the factory at 40 kg, which is in the middle of their tension recommendation. Giving it the finger test as I used to do with my 2014 S it certainly feels tight.  I sure hope that the belt, as tensioned, isn't putting too much stress on the drive-line bearings.

The groaning sound when starting from a stop sure sounds like the motor is straining, even when in "sport" mode.  My 2014 S didn't make that noise.  ???

On my 2017 SR that is using the same belt as your Zero the pitch is lower note and i like that. It make the frame to resonate from different locations  than the 2016- witch had higher pitch, making a more agressive sound than the HF chime of the 2016-  132-30T..

I hadn't thought about that.  You may be right.  The wider belt and greater tension than used on my 2014 S might be the reason for the "groaning" noise that I am noticing.  Makes sense.  ;)

The biggest difference between my 2014 S and my 2018 S is (by far) the Showa suspension.  While performance feels about the same, the much better Showa suspension, compared with the previous Fast Ace components, really makes an improvement in the riding experience. As set up by the factory, the suspension is firm but compliant. Better than most motorcycles that I have owned - including my 2016 BMW R1200RS, with its "semi-active" electronic-adjusted (Sachs) suspension. But, with all of the various adjustment dials to play with I just had to spin a few last night.  ::)

Adjusting the Showa suspension damping dials is really easy.  Much easier than it was on the Fast Ace components, primarily because they are easier to access.  And I bet that they actually perform some useful function.  ::)  However, the only tricky adjustment issue is changing the preload on the rear shock.  While the ramp preload adjustment system is much easier to use than the screw system used on the Fast Ace shock, it would have been really nice if Zero provided an adjusting wrench with the bike - or at least sold one as an accessory.  Fortunately, I have about 10 shock adjusting wrenches in my tool kit and, after trying several, discovered that an Ohlins shock preload adjustment spanner worked perfectly to also adjust the preload on the Showa shock's spring.  The only problem that I had was that I needed the shock handle to be longer to provide enough leverage to get past the bumps in the adjustment ramps.  So I found a hollow metal tube to place over the handle to extend its leverage and was able to easily reduce the preload slightly to accommodate my lighter weight.  :)

Here is another tip:  If you want to check the movement of your front suspension, you can place a plastic zip-tie around one of the fork tubes, next to the fork seal, go for a ride and you will be able to see how far down the suspension compresses, to make sure that the movement stays within an acceptable range.  What I do for the rear shock is to spray the shock shaft with silicone lubricant.  After riding around a while you can look at the shock shaft and there will be a ring around it (like in your bathtub after taking a bath) and that will give you an idea how much movement the rear suspension is experiencing.  I like to keep the movement just above the nylon bumper, which will provide some additional cushioning should you hit a big pothole, or the equivalent.

Here is a comment about the brakes:  The front brake on the 2018 is about 25% stronger than the Nissan brake on the 2014.  However, the rear brake on the 2018 is about three times stronger than the very weak rear brake of the 2014.   :)

Here is another difference between the 2014 and 2018 models:  I live at the top of a hill and on the 2014 S the bike's regen would turn on and off on the way down the hill when the battery pack was at 100%.  This no longer happens with the 2018 S.  I can ride the brakes lightly all the way down the hill with the battery pack topped off and regen maxes out on the display without any regen cutout.  That is a nice improvement.  :)

My S will be fully paid off in April 2019.  That's when I'll consider trading it in (it'll already be a year out of warranty) and I can't wait to see what improvements will be available by then.  Unlike some of the comments I've seen in here, I have been very impressed with the annual progress I've seen in these bikes, yet the prices pretty much remain unchanged year to year (the exception being the new 14.4 kWh batteries in the "R" models bumping their prices slightly).

I'm just keeping my fingers crossed they have some "exciting" colors for 2019, not the flat out BORING palette they adopted for 2018.

One odd thing that happened last night was when I pulled the charger plug, the green charging light stayed on, as did the dash display.  I didn't notice this until this afternoon.  When I turned the ignition on and then off, everything went blank, as it is supposed to be when unplugged.  ???  I checked the condition of the batteries using the Zero app and they showed 15.138 kWh and a 100% charge.  Cell balance ranged from 1mv to 3mv.  So I don't know what was going on but apparently the dash staying on all night while the bike was not plugged in, didn't seem to hurt anything.
