50,000 Emission Free Miles

On February 12th, exactly 20 months to the day that I picked up MINI-E #250, the odometer turned past 50,000 miles. That's 610 days of driving this wonderfully unique car, and averaging 82 miles per day, every day I have had it.

Every day I drive down the road I look around at all the cars around me and realize I'm driving the only car in sight that's not spewing pollutants out the back of my car for the people behind me to breathe. Soon I'll be joined by Chevy Volts (at lease while they are in charge depleting mode), and Nissan LEAF's, but I've yet to run into one while driving yet.  It won't be long before there are then Ford Focus EV's, the Tesla Model S, Toyota RAV4 EV's, and the BMW ActiveE which I'll be driving in about seven months when I have to turn #250 back over to BMW.

No doubt the electric car renaissance is happening, and just about every major auto manufacturer has an electric car in development, and many are near production. That wasn't the case back in June 2009 when I took possession of my MINI-E. The only real electric option at the time was a $100,000 Tesla Roadster, no doubt an awesome car, but a bit out of most people's price range.

So I'll keep driving and charging my car with electricity I produce with my solar PV array on the roof of my home. I'll continue to drive by gas station after gas station, unconcerned about the current price of gasoline. (What does a gallon cost nowadays anyway?) By my account, I would have had to buy about 2,800 gallons of gas for my other car, a 2009 Toyota Tacoma if I did not get selected to be in the MINI-E program. I would have also needed about 10 oil changes, replaced my brake pads at least once and would now be due for a complete 50,000 mile tune up in addition to a litany of regular maintenance items like air filters & fuel filters. I figure I've saved at least $5,000 in fuel and maintenance, and it's probably really closer to $6,000.

Electric cars are extremely low maintenance, which is one of the main reasons the auto manufacturers haven't been really keen on building and selling them. They generally make more money maintaining and fixing your car than they do when they sell it to you. That's won't be the case with EV's. The one big maintenance cost is a replacement battery pack and that won't be necessary for 100,000 to 130,000 miles and 6 to 10 years after the purchase. Even then, they won't profit from it nearly as much as they would have from all the maintenance needed for an internal combustion engine car.

So honk and give me a wave if you see me out there driving around New Jersey. If the "EF-OPEC" plates or the "Starve a Terrorist, Drive Electric" bumper sticker aren't enough for you to tell it's me, just look for the MINI Cooper without the tailpipe sticking out of the back, there aren't that many of us around.

Pushing the Limit

 

The MINI-E speedometer and power gauge

During my eighteen months with MINI-E #250 I have tried to test the car in every way. I have pushed the range until I thought I would need to be towed, I have overloaded the cabin with hundreds of pounds of cargo, I have seen battery temperature extremes from 118 degrees to a low of 39 degrees and I've generally driven it like someone that is trying to find the weak links so BMW could identify them and improve upon the findings in future models. 

I have also not forgotten to test the 95mph electronically governed top speed either. In fact, on a few occasions I have tried to push it a little higher and beat the limiter. I did succeed to squeeze out 96mph, but not any more than that. I was really hoping to get a bit closer to 100, but after a few attempts I have all but given up. When you hit the 95 mph limit, the car cuts the power until it drops down to about 90 and then supplies power again, so you constantly bounce between 90 and 95 if you just keep the accelerator floored. I even tried to do it going downhill with the hopes that I could squeeze out a few more mph but it didn't happen. 

It's not that the car doesn't have the power, because it does. In fact, at high speed it has plenty of power and gets up to the 95mph limit with ease, but the electronic limit then takes over. I'm not sure if BMW just doesn't want us to have an accident at such high speeds or if perhaps the car just isn't geared to go faster and could have problems if we were to drive it to the limit. There is also the issue of battery use at these high speeds. The car uses a lot of power pushing the air out of the way at these high speeds. From my experiences I surmise that driving the car at 90+ mph continuously would cut the range in half of what the car would normally get so you wouldn't want to drive that fast often unless you were not far from your charger.

I think it's that reason that the other automakers that are coming out with pure electric cars in the near future have all set electric governed top speed limiters like the MINI-E has. For example the Nissan LEAF is limited to 90mph, the Smart Electric Drive can only go 60mph, the Mitsubishi i-MiEV is 81mph, the Honda Fit EV is 90mph and the Ford Focus EV is limited to 85. I'm pretty sure these cars, without the limiters could go much faster, but they would then use up the energy stored in their packs extremely fast and possibly leave their driver stranded and unable to make it to their nearest charge point. 

Personally I don't think there is much a need to go faster than 80mph in an EV (unless of course it's a Tesla Roadster!) so I don't mind the limiters as long as they are at least 80mph. In just about any driving situation, you wouldn't need to go faster than that to keep up with the flow of traffic on any highway. As long as the car has the instant torque and plenty of low speed power you would expect with an EV. The trade off you sacrifice in range just to drive a little faster just isn't worth it. I know I'm driving a little slower than I used to now that I'm driving an EV(except when I'm testing the top speed limit of course!) and when I think about it, I guess that a good thing.
