Range On Interstate

I pick up the 2016 Smart electric car (base model) from the dealer tomorrow. It is about 80 miles from the dealer to my house. The car when charged 100% shows a range of 63 miles. I am planning my route The first part of the trip is on interstate highway. The terrain is flat, temperature in the 70s with no rain and if I do the minimum speed required (55 mph) what kind of range can I expect before I head to find a charging station? Thanks.

I don't own a smart ED, but have had to think along similar lines with a first gen Nissan Leaf. Regardless of what range you might be able to get depending on conditions (wind direction, temps, heavy rain, etc.), you'll need to identify multiple possible charging opportunities so that you have options in case of interstate accidents, detours, and higher than anticipated consumption due to battery degradation/issues. Use the PlugShare app/site to check out options. You can also look for individuals that share their home charging station and make arrangements if they are conveniently located using PlugShare.

And, air up the tires to max for the lowest rolling resistance for this one way trip at low speeds to maximize range. Skipping the A/C and heat and anything that draws energy of course to also maximize range unless you need it for clearing windows in rain, etc. Rain can affect things with headlights, wipers, more drag, slogging through traffic congestion due to heavy rain, etc. and you can't do anything but be prepared with charging options on low range EVs.

Of course, there is also the option to have it delivered or tow it with another vehicle if you just want to eliminate the variables. But, if you're up for an adventure, then go for it.

I just did a 150 mile trip in mine a few weeks ago. I did opt for non-interstates and kept my mpg to under 50 mph for the most part. I was good for mid-80's range. For you I'd plan on finding a charging location by 70 miles at least. As for accidents, slow downs, etc., unlike an ICE, that's the best thing can happen to you in an EV. Your range will actually increase.

Set your trip up with at least one charging source along the way...


... or plan on carrying a REALLY long extension cord!

Good luck!

Thanks all for the input. I've thought of everything you mentioned, except the tire pressure, so I'll make sure the dealer does that. Also to keep the windows up at higher speeds to reduce drag. I'll be driving through an urban area (Chicago) then into Northwestern Indiana. The ChargePoint map shows lots of stations along my route. I hope to make 40 miles (half way) and then charge. My grandson will be following me in a regular car. While charging we'll take an Uber to a food place.

It's a 80 mile trip so I hope to charge only once.

Tom, Have someone follow you, in a pickup truck. Caring a Honda generator.
You should just play safe, and tow your car home.

Good Luck.

Why take an Uber? Why not take the car the grandson is driving?!

Even if the minimum speed is posted as 55 mph (a fairly high speed minimum), you might find that going 50 mph saves time on the trip overall (by allowing you to spend less time charging, perhaps even 0 time charging). If the highway is 3 or more lanes wide, going slowly in the rightmost lane is rarely dangerous and range really falls off over 40 mph as you're pushing a fairly non-aerodynamic shape through the air. If you have a cooperative ICE car, you can also draft that car at a "barely safe" following distance to increase range.

As always, you're always responsible for driving safely, but getting max range from an electric isn't quite as mindless as driving 100 miles in a gas car.
