I took my entire family plus a dog on a 700-mile weekend trip in a Tesla Model X — here's what happened (TSLA)

The Model X is Tesla's offering for American families: a stylish SUV with seating for up to seven plus cargo space for gear and room for a pet.

It checks those boxes while looking like a spaceship with a dramatic extended windshield affording a view of the sky, falcon-wing doors, and all-electric propulsion. It can also, at the P100D trim level — which means it has a 1oo-kilowatt-hour battery pack and a dual-motor all-wheel-drive system — streak from zero to 60 mph in about three seconds. Hang on to those Game Boys, kids!

I took a Tesla sedan, the P90D, on an adventurous road trip with . And I spent some time behind the wheel of the Model X after it was rolled out. But I'd never gone on a deep dive, testing the vehicles' full capabilities, from seating comfort to ridonkulous speed to Autopilot semi-self-driving technology to the true secret sauce of Tesla-ness: the extensive Supercharger network and the in-vehicle algorithms that enable you to hopscotch between them.

Tesla rectified that by setting me up with a Model X loaner — a fully loaded P100D that most likely cost about $150,000. It arrived in a glorious glossy black with a creamy white leather interior. Into the available seating and cargo space I would place myself; my lovely wife; our two handsome sons, James, 12, and Dante, 7; our talented daughter, August, 14; and our cheerful new dog, Marco (2, we think).

We loaded up on a Friday in autumn. Our destination was 340 miles southwest: Deep Creek, Maryland. We had Superchargers and more adventures in front of us. Here's how it went.

The mighty Model X! That trippy hue at the top of the windshield is due to condensation on the tinted, extended section.

The car is indeed a spaceship for the road. It's sleek and aerodynamic on the outside, with a "2001: A Space Odyssey" white interior and those famous falcon-wing doors.

The badging that identifies the model is modest.

"P100D" signifies a Performance variant of the Model X, with a 100 kWh battery pack, and a "Dual" motor all-wheel-drive setup. In "Ludicrous Mode," the 0-60 time is supposed to be about three blistering seconds.

The Tesla fob ... looks like a Tesla!

The interior is genuinely premium without overdoing it. It's also roomy and airy, thanks to the lack of gas powertrain. There are just two electric motors and a huge electric battery pack under the floor.

Our Model X had a three-row seating configuration — room for seven. Just not really seven adults.

Row three, seating for two. Or in our case, a single kid. I folded down one of the seats to increase the cargo area.

The seats themselves are extremely comfy. They feel as if they're made of memory foam. The leather was butter-soft. I'm not sure how much punishment a white leather memory-foam interior can handle, but we'll find out.

The X would — on paper — provide plenty of room for two adults, three kids, a dog, and enough luggage to cover us for a few days.

I put one of the kids in charge of the dog while I packed the Model X.

Time to load up! Deploy both falcon-wing doors! Deploy rear liftgate!

And don't forget the frunk! Yes, because there's no engine, the entire front bay can be used to haul stuff. This came in very handy.

Loading the cargo area.

More loading!

Time to start adding kids.

The second-grader goes first. He'll have the third row all to himself.

Seventh-grader awaits his fate.

Second row loaded!

Beautiful wife arrives!

We haven't forgotten anybody ...

... Not even Marco the dog.

Batten down all the hatches.

We have our supplies!

Let's roll!

We have a nearly full battery to start out, with a range of over 250 miles (the max range is 290 miles).

We will spend a lot of time interacting the with the massive central touchscreen. Almost all vehicle functions are controlled with it. The navigation system will route us through Tesla's Supercharger network and, helpfully, let us know how many stalls are open at a given location and calculate how much juice we need based on how far we have to go.

The screen changes its look at night.

The instrument cluster provides additional info.

For what it's worth, I also downloaded the Tesla iPhone app, which linked with our Model X, nicknamed "Lil' Scrappy." Apart from keeping track of charging ...

... the app can manage climate controls ...

... and keep track of how much more charge a trip will demand. The app will alert you when your charge cycle is nearly finished so you don't incur Supercharger "idle" expenses.

Supercharger access for new owners has been free for the life of ownership, but Tesla is going to start charging a fee to recharge as the mass-market Model 3 begins to hit the streets.

The app also lets you drive your Model X like a remote-control car, "summoning" it to move forward and back.

A mix of sun and clouds greeted us as we took the highway.

After a while I could relax and lose the hat.

Yes, we used Autopilot during the trip. It was useful, but I also found myself taking over the steering quite often.

Read about Autopilot versus the competition here.

Long ride. Boredom sets in. But the Model X is a nice place to spend time.

And thankfully we had my daughter's playlists to keep us company.

This feature will wind up being helpful. It graphs our real-time power consumption against how far we have to go before we can stop to recharge.

Electric cars invert the consumption patterns of gas vehicles. An internal-combustion engine requires less fuel to maintain a steady 55- to 65-mph pace, so on the long trips, fuel burn is optimal.

EVs, by contrast, use more power to maintain high speeds and don't have regenerative braking to fall back on for little recharging bumps. So if our Model X says it has 250 miles of range, and most of that is highway, we're going to use up that power. The graph here should help avoid any surprises, though.

We will need to charge up a few times between suburban New Jersey and our destination in Maryland.

For the trip down, I decide to err on the side of caution and make an extra stop, defying what the Model X says it needs.

Plugged in and drawing juice!

Sure, I look as if I'm having a rockin' good time, but ...

... even Marco knows I've screwed up.

Why? Because it's going to take us 10 HOURS to make a six-hour trip. Grrrr!

I was scarred by my previous long-range Tesla drive, when I "ran out of gas" and had to make use of some rather slow charging options to make it home.

Look, there's no way around it. In a Tesla, you can't just pull into a gas station and in 10 minutes get another 400 miles of range.

BUT you can trust Tesla's onboard algorithms to perform good range-to-charge calculations. I really should have accepted that the Model X knew its batteries better than I did!

My father is an idiot!

You can monitor the charging process using the central touchscreen.

And while you wait you can hang out and take in the sights. Our first stop was in Pennsylvania, and we debated about dining at this burger joint.

Other locations on our route were more sparse, although ...

... we finally got to experience Sheetz!

Is it better than Wawa?

A Sheetz feast!

Yep, we drove through the daylight and were still charging at night.

We threw in the towel and stopped for dinner. At this point, my kids were not Tesla fans.

We eventually got to our destination and were rewarded with a glorious following day. Everybody forgot what an idiot their father is and realized that blaming the Model X was pointless.

We took in the local culture ...

... chilled ...

And explored nature.

A few days later, we loaded up to return home. And THIS TIME I decided to trust the Tesla.

Off we go, on a beautiful day for driving.

Woof! Whadda car!

Homeward bound. We made one fewer charging stop and got home two hours faster than on the drive down.

And I brought the Model X back home to Manhattan. The takeaway: When it comes to road trips in the SUV of the future, TRUST THE TESLA.
