This is an ongoing journal of my first few weeks with Model Y. Check Day 1,  Day 2, Day 3

One of the most important jobs for our Model Y is getting the whole family up to our summer/ski condo in Vermont from our home outside of NYC. The trip is around 180 miles. Our Model X 90D would get such poor range that we’d almost always have to make a Supercharger stop along the way, to make it with confidence. I should note that the route is quite curvey and hilly and the last leg is climbing a mountain, so it isn’t a straight shot by any means.

So one of the things I’m hoping to get from the Model Y is the ability to make it the whole way comfortably, without charging. To make it more interesting, we added bikes to the back, using our freshly installed tow hitch. Would the Model Y be able to make it?

A little more background first. Our Model X, which I’ve discussed at length, was pretty much the definition of a lemon. Throughout our 3 years with the vehicle, it had a bad axle which probably contributed to its poor range. It was a floor model, probably, from Tesla so we got a significant discount on it “as is” but grew to regret that decision. It came with the 22-inch turbine wheels which was gangsta and really added to the Falcon Wing door ensemble when I was dropping off the kids at school, but apparently they were also pretty horrible on the car’s range. I all but verified this fact by getting better range with 20-inch snow tires in the winter vs 22-inch gangsta wheels in the summer. The point is, we’re not starting from a very high bar here.

Model Y as a trip car

The Model Y delivery experience was very good and crazy efficient. There were some panel gaps and a stain on the interior but Tesla, to their credit, sent a ranger out to the house on Friday to do some minor work. The technician was super professional, friendly and knowledgeable and even checked over my tow hitch installation and readjusted a few snaps that looked fine, but I hadn’t realized weren’t placed properly.

I set the Model Y to charge to full Friday night on my Juicebox charger, to prepare for the big trip. When I woke up in the morning, charging has stopped with 307 miles and I got a 12V battery warning. I’ve had these before and sometimes they are due to abrupt charging changes, which may have been caused by my. Juicebox turning off at 8am. (I’m in ConEd/Fleetcarma Smartcharing rewards program so I get handsomely rewarded for only charging from midnight to 8am.) Since I’ve had the 12V warnings before, I knew it was OK to drive with it and, incidentally, haven’t seen the warning since.

As an aside, if you want to know what it is like to write about Tesla in any sort of even-handed way, check out the replies on the above Tweet from both TSLAQ Tesla haters and the separate vitriolic superfan thread. Which side is worse? I guess I know I’m doing well if I’m pissing both sides off?

Anyway, I replugged in the charger, turned on the AC inside the car and started packing for the trip.

Model Y trip packing cargo space

Some Model Y cargo observations vs. Model X:

  • The Frunk is wider on the Model X but Model Y’s feels deeper.
  • The space underneath the floor of the trunk is gargantuan in the Model Y compared to the Model X. Most of our belongings for the 2 week trip fit here.
  • Our 50lb. husky takes up the rear area of the Model Y, which isn’t as big as the Model X in any dimension but still big enough for her to move around and be satisfied. No complaints from her.
  • The same Thule bike rack that had allowed the Model X’s trunk to open doesn’t do the same for the Model Y. The trunk hits the rack if I try opening it. Maybe I can extend it out a little – it is close. This means we have to change our process a little. Doggo will have to enter and exit out the rear passenger doors. NBD.
  • My 2 boys (11 and 9) like the rear seating area but had more independence in the captain’s chairs of the Model X. But, they certainly appreciated the pockets on the back of and storage underneath the front seats, which is an upgrade from the X.
  • The USB-C chargers allowed them to charge their Chrome/Macbooks while driving, which is an upgrade over Model X. The armrest/cupholder is also a welcome addition, but of course was a cause for a fight or three during the 3+ hour trip.

Loading up the bikes is fairly easy and because of the aforementioned rear door closing issue, had to be done last. The final step is putting the dog in the back which we now did through the rear passenger door. putting down the single seat. We bribed her with treats and might have given her a small CBD/Benadryl cocktail, hence the derpy look, don’t judge!.

Model Y trip

Once we mapped in our destination, the computer estimated we’d arrive with 32% of range left. That ended up dropping down to about 25% during the trip, and remained consistent (likely because of the bikes). We take the Taconic Parkway, which is winding and hilly most of the way with a 55mph speed limit.

I set AutoPilot at 64mph, which puts us in the right lane most of the time (if you don’t know, NY drivers are agro). With 4 passengers and the dog, AC set at 71 degrees fahrenheit and most importantly, the bikes on back, we averaged about 320 Watts/mile on the highway. That’s about an extrapolated range of 240 miles on the 75kWh battery, or about 76 miles less than the normal the 316-mile range.

After the Taconic, the second half of the trip is back country roads, which have a similar speed limit but with significant drops as we go through small towns.

What’s amazing is that even with the bikes, I was getting significantly better range than the Model X would without bikes. Comparatively, the Model Y is a marvel of efficiency.

The last leg of the trip is up a mountain outside of Manchester, Vermont which is obviously very taxing on the battery. The flip side is that going back home is easier and we can regen some range right at the beginning, if we don’t want to charge to full. Bottom line, if we can make it there, we can definitely make it back.

Model Y success!

We ended the 174.3 mile trip with 28% — or about 92 miles — of range left, easily making the trip with plenty to spare. Again, that’s with the bikes on back.

Model Y: The perfect trip car?

Obviously, I’ve not done any long term trip testing yet, but our first test was a resounding success. The bike hitch worked well and the bikes arrived working perfectly. Everyone was comfortable during the trip and the car was everything we needed from it. There was no range anxiety once we got on the road. Even acceleration was still amazing with everything including the bikes packed up. It was easy to forget that the bikes were even there.

With the almost 100 miles of excess range even while packed to the max, I’m confident I can make it up here without charging stops in the winter, especially when it is very cold. It will be interesting to see how the Octovalve heat pump helps battery range there. With Supercharging and without the bike rack, I’m fairly certain 300+ miles between supercharging stops will be easy to attain, even at much higher speeds.

Every family is different and ours is relatively small but for our 4+dog crew, the Model Y looks to be the perfect trip electric vehicle and a big upgrade over our Model X experience.
