Just like the other suburb drives I've filmed, this one takes me to that distant
coffeeshop. The run back & forth is a good basis for demonstrating what happens
as the EV capacity is utilized, then what happens after it's gone... which is
why I filmed that same route prior to getting the plug-in model. You can clearly
see the benefit.
This footage featuring that rare lighting circumstance when a single camera can
be used. Too early or too late, there will be over & under exposure. The refresh
of the screen will become an annoying flicker as well. In this case, I took
advantage of the sun setting with the horizon obscured by clouds. It provided a
nice balance between dashboard and scenery, as well as show a nice pink in the
final moments before the sun disappeared.
As for the drive itself, shown at 5X normal speed, you can see me pull out into
traffic driving in just EV. But with a route longer the total capacity
available, I fired up the engine right away. That resulted in a boosted MPG
until warm-up is complete, then the engine shuts off. Watch the estimated EV
distance value. I suddenly drops from 9.6 to 8.5 when I turn on the heater to
blow air on the windshield to keep it clear for the filming. Capacity itself is
unchanged. That's simply how you are informed of the potential EV loss the
heater could cause.
Driving was uneventful, the usual stoplights & stopsigns you'd encounter driving
through the suburbs. When accelerating hard, the engine will come on to help
provide power. Watching the MPG, you can see that doesn't actually lower MPG
much and it shuts off relatively quick afterward. In the summer, it shuts off
even faster. But at 28°F outside, it runs longer.
Halfway through my drive back, you can see me approach a long hill. Climbing
that with only 1.8 miles of EV remaining wouldn't be the best use for that
electricity. So, I switched over to HV mode by pushing the button for that on
the dashboard. When at the top, I pushed it again to switch back to EV mode.
That feature comes in handy when you want to preserve electricity for use later.
At the conclusion of the drive, the overall result was 135 MPG for the 15.7 mile
round-trip. The entire EV capacity was consumed; that's roughly 3 kWh of
electricity including charging losses.
That was a great drive for winter, but I sure miss summer. In warmer
temperatures, resistance with the battery itself is lower. That more efficient
transfer of electricity allows you to drive further EV from each recharge. So
whether you use gas or electricity, cold weather reduces efficiency.
