Nissan LEAF Owner Reviews the i3 After 3-Day Extended Test Drive

I have always maintained that a good number of i3 buyers will be Chevy Volt and Nissan LEAF owners that have just finished up the three year lease on their vehicle. Phil Tipper is an EV "early adopter" and leased a Nissan LEAF. His lease will expire next spring so he's trying to decide which plug in vehicle he'll get next. The i3 is on his list of possibilities and when BMW recently offered the i3 extended test drive Phil  jumped on the opportunity to get to know the car a little more. I love this extended test drive offering from BMW. I think it's a great way to give prospective customers a chance to absorb what the i3 is all about. Phil is already an experienced electric car driver so he could focus more on the specific features of the i3, but many others who have never experienced electric drive will find the extended time they have with an i3 intoxicating. Having more than a few minutes during a quick test drive at a dealership will absolutely help convince people that may have been on the fence. It's simple, the more you drive electric the more you like it. That extra time behind the wheel may be all they need to make the decision to go electric for the first time. Phil wrote of his experience and thoughts on his time with the i3 and posted it to his blog. I thought is was interesting to hear what a Nissan LEAF driver thought of the i3 so I asked him if I could post it here and he obliged. Below is the post from Phil's personal blog:

As regular readers of my blog know, I'm actively researching the next electric car to replace our 2013 Nissan LEAF SL when its two year lease expires next June, and that the BMW i3 is on the top of my list of contenders.

I like the BMW because of its light weight for an EV (because of the carbon fiber structure of its "life module"), giving it the potential for good energy efficiency and promising good handling around corners, because it has a relatively powerful and torquey motor making it quick off the line, because BMW has tuned in tight steering and minimal body roll, because it is a rear wheel drive design (for classic sports car handling), because I like BMWs and I like the personal service that a premium brand provides, and because I can get a model with a range extender that offers a total of about 150 miles of range, with more range available with a fill-up of a tiny bit of gasoline. I like the idea that a range extender will let us take trips as far as Santa Barbara and San Diego without worrying as much about the reliability of public charging and the time recharging would take.


I'm also fascinated by the concept that having a range extender as a cushion will actually let us, paradoxically, drive more electric miles because we'll be more likely to take the EV than to fall back on the Prius, and because we'll be comfortable dipping deep into the battery's charge because the range extender will be there as a cushion and we won't risk needing a charge to get home.

On brief test drives of the i3, I had been able to briefly sample the car's quick acceleration and tight steering, but I'd had trouble getting used to the strong regeneration when the accelerator pedal is released, and I had even felt a bit of vertigo, especially as a passenger when the car was driven vigorously. So I had some concerns to resolve. On Facebook and in person, drivers of the i3 had told me that these concerns would resolve themselves quickly after I had gotten more used to driving the car. A longer test drive was needed.

To my delight, some BMW dealers recently began offering three-day test drives of the i3. This was exactly what I wanted. I found a dealer within 25 miles of my home that was offering the long test drives, Shelly BMW in Buena Park, California, and I found their internet team responsive and easy to work with. I thank them and applaud their willingness to take on the bother and expense of offering this program. To me, the BMW i3 is a car that benefits from a longer test drive so that the customer can learn its unusual.driving dynamics. In fact, I think that brief test drives around the block can be misleading, mostly because of the strong regeneration. I picked up a base model "Mega" i3 with the range extender engine and the optional 20 inch wheels and tires last Thursday morning.
Here are some of the comments about my experiences that I posted on the BMW i3 Facebook group.
Random impressions from first 24 hours, 150 miles:
Regen braking:


It's pretty much a non-issue and I beg to retract all of my earlier doubtful and even downright negative comments about it. It is different, but it is manageable and you adjust fairly quickly. I would still like to have the regen strength adjustable for a more relaxed driving experience in certain situations. At low speeds with this car, you WILL brake significantly if you need to lift your foot to readjust its position on the accelerator, and it would be very nice to be able to reduce the regen power if you just want to relax and coast with your foot off the pedal for a few seconds. Also, as many have said, the regen strength is lower at high speeds, so you don't go into full-on braking at freeway speeds if you lift off. My wife's first test drive comes in a day or so, and I expect her to have issues learning to drive the car smoothly, and I also expect uncontrollable giggling at some point during her test drive (from her, not from me). But I was able to drive her on a day trip today without her feeling too jerked about. And that was in both Comfort and EcoPro modes.

Ride and handling:


The car does bounce around a bit more than I like on uneven pavement in situations when I want a smooth ride, especially when I have a passenger. When I'm out for sporty driving by myself, the ride is tight and just fine for me. I put a lot of this down to the short wheelbase that allows the car to bob over bumps, and the 20 inch wheels with low profile tires. I had mentioned getting just a touch motion sick on short test drives before, but I have to say that I really haven't felt that in my first full day of driving the car. I imagine that having a chance for my inner ear and brain to get used to the car has something to do with that. I'll just say that the car is less relaxing to cruise in than my Leaf is because the steering is very responsive to any turning input and I find that I have to pay more attention to where the car is in the lane than I do with the Leaf. Some would say that's the price you pay for responsive steering. Fair enough.

Sporty driving:

Oh hell yes! You owners know this, but I think that the best kept public secret about the i3 is that there is a little sports car demon hiding inside this little thing. When I'm driving alone on a twisty, hilly road, it feels as good as any sports car I've driven (remember that I'm in the Mazda, Nissan, 3-Series class, not the Ferrari, Porsche class). The skinny tires grip on curves like the devil and the torque of the motor just goes on and on. Very, very grin-inducing, and very BMW. For me, this is the one and only reason for ME to get this car. Frankly, a fully optioned Leaf SL or a Mercedes B Class EV would do as good or better job for family cruising duty. They are more spacious and more relaxing to cruise around in. But in my experience, the i3 is more fun to fling around than a Tesla Model S because of its small size, light weight and tight handling. And I've driven a Model S on some of the same twisty roads. Given that I'm limited on parking space and we can't really have more than two cars, my EV has to be my fun car as well as being practical. Since the FUN potential of the i3 is so high, I can probably live with the practical downsides of the car.

Performance on Rex:

I haven't had much time driving the car in REx mode, but I purposely ran the battery down so that the car would go into Rex. There is a slight, almost unnoticeable vibration in the cabin, and you can hear the two cylinder motor chugging a little back there with the windows up. I drove the car fast up a pretty steep hill with the REx running and there was no reduction in power that I could detect. I must say that I do like having the REx there as a cushion. I've been driving EVs for over three years and I know how to handle range issues, but it was very nice to see a 40 mile cushion on the dashboard as we finished our 70 mile trip today (Note: The gas tank was less than 3/4 full).
Driving efficiency:

If the mi/kWh onboard readouts are to be believed, I'm getting no better efficiency in the i3 than I do with similar driving in my 2013 Leaf SL. I expected something like 20% better efficiency in the i3, but as near as I can tell, Nope! (Note: see my revised comment on efficiency near the end of the article.) You might say that I must be pushing the i3 harder, but after a day of cruising with my spouse aboard, I got around 4.2 mi/kWh, which is what I'd expect from my (heavier) Leaf in the same kind or driving. This was a mix of suburban and freeway driving, in a mix of EcoPro and Comfort mode. Go figure.

Random minor observations:
I like having frameless windows on the front doors. Getting in and out of the car is a pleasure when I don't have to contort to get around the upper door frame.

I like the placement of the 12v power plug for a phone charger. My phone sits down there in that well with the charger plug and I don't have wires everywhere.

The door pockets are spacious and handy for carrying all kinds of small items.

Installing kiddie seats in the back seats was a bit challenging. We have two grandkids, a four year-old and an infant. I had to remove the rear seat headrest so that the bigger kid seat would fit properly down into place. The base for the infant seat takes up a surprisingly large amount of space front-to-rear, so when we put in the actual carrier cradle into the base, the front seat will have to be moved forward a lot. Since I'm long-legged and tallish, we'll have to put the infant base behind the passenger and have her move her seat forward, and we'll have the bigger kiddo sit behind me, the driver, and she and I will have to negotiate over leg room.

Finally (after first 24 hours): No electronic or mechanical gremlins, errors, CELs, nothing. Very reassuring.

And here is my summary of my experience after the end of the three day test drive:

I'll summarize by saying that I liked the car very much, and that most of my concerns were eliminated after a few days driving it.

Positives:


+ The strong regen is a non-issue. It took a long test drive like this to convince me, but I no longer see this as a problem. Even my wife found it manageable. (BUT I do have to mention that she did have a second of unintended acceleration when she wanted to use the brake and forgot that her foot was still on the e-pedal. This was after only ten minutes driving the car for the first time, and we're sure that with more familiarity, this wouldn't be a problem.)

+ The quick acceleration and tight handling were really rewarding and these would be the biggest reasons that I'd choose an i3 over any of the competitive cars. This is really a little sports car disguised as an economical city car, and it's the true standout, as far as I'm concerned, for sportiest small four-door EV. (I know that the Spark is pretty quick, but it's really a tiny little thing and wouldn't work for us as a family hauler.)

+ Material and build quality were very good, even in the base Mega model. I happen to find the interior materials interesting and even the compressed Kenaf panels are fine with me.

+ I liked the maneuverability and tight turning circle.

+ I happen to like the car's unusual styling.

+ We were able to install kiddie seats for our two grandkids and reassure ourselves that the car would work for kid transport duty. This included one rear-facing infant seat and one front-facing kid seat. Space wasn't plentiful. The infant seat base takes up a lot of horizontal (front-rear) space, so it limits how far back a front passenger can move their seat. So we put the infant seat base behind the front passenger so that as the driver, I can get my needed leg space.


Features that I found only so-so:

* Having no keyless entry on the base car is cheesy, especially since the car has keyless-go.

* No option for power seats. That really should be an option for those who want it, with full disclosure that it adds weight and might harm range.

* I still find the seating position too high, and I kept wanting to lower the seat below the lowest setting. Ditto the steering wheel. It feels too high even at its lowest, and the high steering wheel position gives me a kink in my right upper shoulder.

* Loud and uncomfortable wind buffeting with the windows down above about 55 mph. I like to drive with the windows down, and without rear windows to open (or a sunroof) the "air hammer" that happens with the windows down is severe. I found that raising both windows to within about 4 inches of closed helps a lot.

* There was an annoying "reciprocating" thrum that I heard/felt at moderate to low speeds. I was never sure whether it was tire noise or drivetrain noise, or both, but it wasn't a typical EV driveline low howl that changes pitch as you slow to a stop. It was more
of a cyclical thrum that got slower in its cycle as I slowed down. Is this typical for the i3, is it unusual, or could it have been specific to the 20 inch tires? (Update: Tom Moloughney, our i3 online guru, told me that he had confirmed this sound in his own i3 to be coming from the 20 inch tires.)
* The short wheelbase (five inches shorter than a LEAF's) makes the car rock and bob over road imperfections. It's tolerable but it sure isn't a serene riding car. For most of my personal driving, it's no problem at all, but for times when I want to treat my passengers to a smooth ride, it's intrusive.

* I won't get into complaints about the crippled USA REx implementation, but the EV range that I got with the car was an unimpressive 72-ish miles. That's fine for most of my driving, but I'm used to getting about 85 miles with my Leaf, so this felt a bit limited. I do like having the cushion of the REx, though, and I think it would let me drive more EV miles, because I'd choose to take the i3 more often when planned trip lengths are a bit long, and a total range of about 150 miles with the range extender is very attractive after driving a Leaf for three years. It will make the difference between being able to use the car fully and not being able to in the spread-out LA metro area.

* Energy economy was poorer than in my Leaf on the freeway, but better than the Leaf on suburban streets, including with spirited driving. I find this rather disappointing because if I get an i3 REx, I'd like to do more regional driving trips with it, and I was hoping for better freeway economy. OTOH, with the good economy at lower speeds, I can drive it around like a hooligan without any misgivings (free energy from our home's solar roof).
- The "coach" doors. Awkward to move kiddie seats in and out of the back seats unless you have plenty of space on the side of the car. We had to back the i3 out of the garage into the driveway to have enough space to swap the kiddie seats in and out. The maneuver also required removing one rear head rest because it interfered with the upper part of the forward-facing child seat, and this requires partially folding that rear seat forward to be able to remove the head rest. We found that it was also necessary to slide the front seats forward and flip the back rests forward so that we had enough room to get to the child seat restraints and belts.

We wind up needing to swap out the child seats a couple times a week because we have two cars and only one pair of child seats. So this will become a frequent exercise. Not a huge deal, but if it's raining (if it ever does around here again), I'd be either doing this drill in the rain in the driveway, or back the Prius out in the rain to be able to get the i3 doors fully open and move the kid seats in and out. First world problems, to be sure.

- The placement of the charge access door on the right rear fender. I was lucky that I chose a 25 foot cable when I bought my Aerovironment L2 EVSE. Since I mounted the EVSE near the left front fender of a headed-in car, my choices with the i3 are to back the car into the garage or to wrap the cord around the car to get the plug to the i3 charge port. The latter choice was the more appealing one to me, and it worked fine, aided by the i3's short overall length.

* And of course, I find the car's price and value for money proposition disappointing. I'm going to want a good sized discount AND a boost to the residual percentage to feel okay about the lease pricing. We'll see how things are next Spring, when I'm in the market. But BMW really needs to kick in the whole $7,500 Fed rebate, or price the car to make up for the difference. OCF (Owner's Choice with Flex - a purchase program with a guaranteed buy-back at the end of the term) programs are less attractive in California because you're charged sales tax on the car's full cost, even though you're only using it for a portion of its life. Leasing would be more attractive to me, but not at BMW's current pricing, rebate amount and residuals.

Lastly, the only issue or problem I had in three days and 265 miles was a problem with " low cost charging". Even though I had set the car in that mode, it insisted on charging immediately. This was with Level 2 charging with about 15% SOC remaining.

And by the way, my existing Aerovironment Level 2 home EVSE with Nissan badging worked great with the i3.

Breaking: The i3 Rex is Indeed Tax Exempt in New Jersey After All!

My i3 REx in front of my house with my 8.775 kW solar array in view 
In a surprising turn of events, the New Jersey Department of Environmental Protection (NJDEP) reversed a previous decision to exclude the i3 REx from the States Tax exemption for zero emission vehicles. This hopefully ends the nearly six month saga from the time it was originally thought the range extended version would indeed qualify, to the announcement shortly after the launch that it would not.

I actually found out a few days after I bought my car that it would not qualify, and I would have to pay $3,921.00 in sales tax. This was totally unexpected and would have actually made the range extender nearly an $8,000 option for me! As much as I love having it, I wouldn't have agreed to pay that much for it had I known the effective cost would be so high. For $3,875 I think it's fairly priced. But $7,800? No way! I even dedicated a blog post to this issue back in May when the surprising (bad) news was announced. I will say that I never actually ended up paying it all though. That's because my dealership, JMK BMW realized this was a BMW communication error and not the customers' fault. They decided they couldn't go back and charge customers so much more than they had signed contracts for and they honorably worked out a deal which made everybody happy and nobody cancelled their order. My client adviser, Manny Antunes, sold eleven i3s with range extenders so this wasn't an easy decision but the dealership decided it was better to keep the customers happy than to call them all up and tell them they now owed nearly $4,000 more for sales tax. 

However that wasn't the case with other dealerships, and I know people who bought REx cars and had indeed paid the every penny of the sales tax and didn't get any other dealership rebate or credit. They will be very happy when they open the mailbox one day soon and find a nice check in there because this decision is retroactive to May 1st, which is before any i3s were sold in the US. I was actually the first i3 REx delivery in the US, and that took place on May 21st so all i3 REx cars sold in NJ will indeed qualify for the ZEV tax exemption. 

The NJDEP Zero Emission Tax Exemption list has already been updated to include the i3 REx and can be viewed here. Let's just hope this ends the, "It's tax exempt…no it's not," saga we've had here in the Garden State.

How Much Does it Cost to Charge an Electric Car?



There are many reasons for considering making an electric car the next car you buy or lease. Besides the many environmental benefits, the promise of energy security, the silky-smooth driving experience with instant torque available without delay and low maintenance, one of the best characteristics of electric vehicles is how little they cost to operate. I've covered this topic here before, but this is something that really needs to be driven home. While Electric cars are currently more expensive than their conventionally-powered counterparts, the total cost of ownership over time can certainly be less, and in some cases much less.

Just as with gasoline cars some EV's are more efficient than others, but the average EV needs about 30 kWh’s of electricity to power the vehicle for 100 miles. For example, the EPA rating for the Nissan LEAF is exactly 30 kWh’s per 100 miles. A Tesla Model S 60 is rated at a combined 35 kWh’s per 100 miles and uses a little more energy since it’s heavier and more powerful than a LEAF, while the Chevy Spark EV has a combined consumption rating of 28 kWh’s per 100 miles. The BMW i3’s EPA consumption ratings haven’t been announced yet, but since the i3 is likely to be wear the “most efficient EV” crown, I expect it to be rated somewhere around 26kWh’s per 100 miles. The consumption for all electric vehicles can be viewed at the US Department of Energy’s website: www.fueleconomy.gov

According to Researchers at the University of Michigan Transportation Research Institute, the sales-weighted average fuel economy of all new vehicles sold in the United States in 2013 was 24.8 mpg. The average cost for a gallon of regular gasoline in the US over the past three years was $3.53/gallon. By using 15,000 miles as the average amount of miles a person will drive in a year, the annual cost of gasoline for the average car will be $2,135 per year, using the average cost of gasoline from 2011 through 2013.

Electricity rates vary much more than gasoline across the country, but the cost is much more stable. Unlike with gasoline, there aren’t huge spikes in electricity rates if a refinery has a problem, and neither does the price skyrocket when there is political instability in one of the large oil producing countries as we have seen lately, since all of the electricity we use in America is domestically produced. The average cost of electricity in the US is 12 cents per kWh. Therefore the average person driving an average EV 15,000 miles per year pay about $540.00 per year to charge it. As mentioned, the cost of electricity can vary greatly depending on where you live, but in order to equal the price of the average gasoline car’s fuel costs, the price of electricity would have to be four times the national average, and cost 48 cents per kWh. Nowhere in the US does electricity cost even close to that much. So the average American would save roughly $1,600 per year in fuel alone, and that's if gasoline prices remain around $3.53 per gallon. Gasoline prices do frequently spike up and down, but in the long run they always goes up. Electricity costs do eventually increase also, but not nearly at the pace of gasoline. Plus with fewer moving parts, EV's cost much less to maintain. If you combine the fuel savings with the reduced maintenance costs, it's clear to see an EV will cost you much less in the long run, even if the vehicle costs a little more up front.

Another great thing about electric cars is that you can easily reduce your electric bill by $40 to $50 per month just by being more efficient, and therefore completely eliminate your transportation fuel cost! You really can't use less gasoline unless you drive less or buy a more efficient car, but you can reduce your electricity usage at home and still drive as much as you always have. Simple measures like a programmable thermostat and the use of compact florescent or LED light bulbs can make a big difference. In fact, five 100 watt light bulbs left on continuously for a year use nearly the same amount of energy as it takes to power an electric car 15,000 miles! Here's how: five 100 watt light bulbs use 500 watts per hour. In 24 hours they use 12,000 watts or 12kWh. In 365 days they use 4,380kWh’s. A typical EV that uses 30 kWh’s for every 100 miles will use 4,500 kWh’s to drive 15,000 miles. Simply by turning unnecessary lighting off at your home, you can drastically reduce or completely eliminate your annual transportation fuel cost. Try doing that with a gasser!
