When most people think about buying a Tesla or switching from gas to electric car, they wonder: 

  1. What’s the price difference between a gas car versus and electric car? 
  2. How long does it take to charge an electric car? 
  3. How inconvenient is it to have an electric car versus a gas car? 

Today I’m going to be answering these questions.  My wife and I drove separately from Southern California to Northern California. I drove the Lexus RX (gas car) and she drove the Tesla Model Y. We left at exactly the same time, drove the same speed, and had the same starting point and ending point.

About the Cars

To provide a better understanding of what we’re working with, here’s a background of the cars. 

2016 Lexus RX 350 

  • 302 miles on full tank 
  • 20mpg in city, 27 mpg on highway 

2021 Tesla Model Y Long Range

  • 303 miles at 100%

Difference between Gas and Electric Cars

With gas cars, you fill your car to full tank to minimize the number of times you have to stop on a road trip. 

However, with electric cars, you don’t want to charge up to 100%. The reason is that the charging speed is faster when the state of charge is lower. For example, at 10% state of charge, you can get 250kw.  However, when you’re at 80%, the speed drops significantly to ~80kw and charges slower. So it may take only 15 minutes to charge from 20-70%, but then take 45 minutes to charge from 70-100%. 

Therefore, it is advantageous to not charge to 100%, as you’ll be waiting forever. This then results in more frequent stops.

Overall Thoughts

Overall, driving a Tesla on a Norcal/Socal road trip compared to a gas car is cheaper by $8, but also takes longer (40 minutes).  However, it is more expensive to charge at Tesla Superchargers compared to charging at home (typically charging at home is 1/2 the price, depending on your electricity plan). So the cost is even cheaper with an electric car. Also the beauty of charging at home is that you wake up, and have a full charge without having to stop at a gas station. 

However, if you’re the type of person who wants to get to your destination ASAP on a road trip, then maybe take a gas car so you won’t have to wait for your car to charge.
