I㽶Ƶֱve had my eye on an electric car for a while now. I㽶Ƶֱve driven four Honda Civics into the ground (and past 300,000 miles) and was intending to do the same, until I met Sarah Bond. Sarah is in grade 11 at Pen High. She㽶Ƶֱs learning to drive in an electric car, specifically a Nissan Leaf, and she㽶Ƶֱs an electric vehicle (EV) enthusiast, with the facts to back her arguments. You should know that Sarah is so enthusiastic, her teachers had to ban the topic of EV㽶Ƶֱs from further papers or presentations!

Sarah㽶Ƶֱs family has three vehicles: A 2013 Nissan Leaf, A 2019 Tesla Model 5, and a gas-powered truck to tow their RV. Sarah says that her family tries to do things that are good for the environment: they take glass to the bottle depot to be recycled, they compost in their yard (they do not yet have urban chickens but her mom wants to get chickens).

However, Sarah says the biggest reason they own two electric cars is because they are a good value. She told me a story about their last vacation: when they bought the Tesla, it came with six months of free charging, so they carefully planned to get maximum value for those six months. They took a vacation, driving down to San Diego, charging for free along the way and staying with relatives. The charging went completely without a hitch, but afterwards her father calculated how much it would have cost without the free charging. From Penticton to San Diego charging costs $80 CAD one way. They really didn㽶Ƶֱt need the 㽶Ƶֱfree charging㽶Ƶֱ to make the trip.

I asked her about the car they had had the longest, the Nissan Leaf which was purchased used five years ago. What kind of repairs had they done? Sarah said 㽶ƵֱTires and windshield wiper fluid㽶Ƶֱ. I found this hard to believe. What about recalls? My Honda has had several in the last five years. Her mother confirmed: No repairs, no recalls.

㽶ƵֱBut this is why you have to buy an electric㽶Ƶֱ Sarah explained with enthusiasm 㽶Ƶֱyou may think it would be better to have a hybrid, but electric engines are really simple. They are cheaper to drive and there are hardly any repairs 㽶Ƶֱ you don㽶Ƶֱt have to change the oil.㽶Ƶֱ

You may think it would be better to have a hybrid, but electric engines are really simple

Sarah㽶Ƶֱs dad elaborated: 㽶ƵֱThere㽶Ƶֱs no pistons, there㽶Ƶֱs no rings, there㽶Ƶֱs no muffler, there㽶Ƶֱs no clutch. In fact the engine is so simple, it doesn㽶Ƶֱt take up much room. The Tesla has a surprising amount of storage㽶Ƶֱ.

It㽶Ƶֱs not just the engine itself that is better designed. In a combustion vehicle we take for granted the continual war between acceleration and braking. In my conventional Honda it would be most efficient to drive across town without stopping (although it might result in a trip to visit Sarah㽶Ƶֱs mom at the hospital). New EVs take the superiority of an electric engine and go one step further by adding regenerative braking: slowing down for a light actually charges the batteries.

Sarah㽶Ƶֱs father tells this story: (Note that in place of a fuel gauge, EVs report the range 㽶Ƶֱ how far they can drive on the current charge.)

㽶ƵֱWe drove this year to Lost Moose Lodge [2200 ft/635m elevation above Penticton ??]. When we got there the Tesla was down to a range of 40 km. By the time we returned home, regenerative braking brought that up to 80 km㽶Ƶֱ.

Sarah chimed in: 㽶ƵֱWe drove to up to Apex this winter, arrived with an 11 km range, and back home that night we had 80 km.㽶Ƶֱ

I asked her about day-to-day charging. Sarah said 㽶ƵֱWe have a normal charger [i.e. Level 2, 240 volts which which requires the same wiring as an oven or a clothes dryer] and the Tesla came with an adapter so we can charge that too.㽶Ƶֱ But as a matter of fact they don㽶Ƶֱt do much charging at home. Sarah㽶Ƶֱs mom works at the hospital, where there are free EV chargers, so when a vehicle needs charging, Sarah㽶Ƶֱs mom uses it to get to work.

Sarah says they drive from Penticton to Vancouver (420 km) several times a year, something that would take planning in the 2013 Nissan Leaf. 㽶ƵֱWith the Tesla, there㽶Ƶֱs one quick stop [at the Hope Supercharger] for lunch, which we would do anyway㽶Ƶֱ.

Sarah㽶Ƶֱs dad ended with a stern warning: 㽶ƵֱDon㽶Ƶֱt go test drive a Tesla unless you are ready to buy.㽶Ƶֱ
