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.

What Should The i3 Be Compared To?


Now that BMW has revealed the production version of the i3, including most of its specifications and the MSRP with and without the range extender option, it seems journalists are struggling a bit when they are deciding what other car to compare it to. The result is, they are comparing it to just about everything else with a plug.

A LEAF charging at my restaurant
Since BMW claims it will have about an 80-100 mi range, the inevitable comparisons to the Nissan LEAF have happened. These have largely said the i3 will be faster, offer a better driving experience, has a nicer interior and offers electronic packages and a range extender that Nissan doesn't offer. At the same time, the i3 is $14,000 more than a base LEAF S, has only a marginally better range, has less cargo room and the rear coach doors will be less functional than the LEAF's conventional doors. The LEAF seats 5, while the i3 only seats 4. Exterior styling is pretty much a push, as both cars have unconventional styling that many have said they do not appreciate.

Others have pit the i3 against the Chevy Volt. There is a lot of sense to this comparison because the i3 and the Volt are the only two electric vehicles that have a range extender. The range extender is standard on the Volt; you can't order one without it, while on the i3 it is an option. BMW has stated that they expect the vast
A Volt on display at Nauna's
majority of i3s sold in the US to have the range extender option and I agree with that line of thinking. The i3 has more than two and a half times the electric range of the Volt, allowing most owners to drive on electric a much higher percentage of the time, while the Volt's range extender is more robust and allows the driver to continue driving uninhibitedly once it turns on, even up long mountain climbs. There is still some speculation that the i3 may have difficulty with long, steep mountain climbs once the range extender has come on. The thought is the REx may have difficulty replenishing the energy used in these extreme situations quick enough, but this is still an unknown. Also, the Volt has a 9.3 gallon gas tank so you can drive it up to 380 miles without stopping for gas. The i3 has a 2.4 gallon gas tank so the total range will be less than 200 miles before needing to stop to refuel. The i3 is faster (0-60 in 7.0 seconds compared to the Volts 8.7 sec). Both cars seat 4 with comparable passenger volume but the Volt has more cargo room. The Volt's recent $5,000 price reduction makes it about $10,000 less than an i3 with the REx option, which should be the version of the i3 you use to compare the two. This is a significant advantage for the Volt and the recent surge in Volt sales is proof that people will buy them in large numbers if they believe they are properly priced. A typical BMW customer is accustomed to paying more than a typical Chevrolet customer, but will they see the i3's advantages (performance, much longer AER, cutting edge tech, carbon fiber construction) as worth the premium is yet to be seen.

The i3's interior is nicer than any other IMO
I believe if you must find an EV to compare the i3 to, the Volt is a particularly good one because they are the only two EVs that have range extenders and I definitely believe many customers will select the REx option. I believe that is true partly because many first time EV buyers will want the security of having the range extender there "just in case" and others will opt for it because they find the i3's electric range to be short of what they want in an electric vehicle. I believe if BMW gave the i3 15% to 20% more electric range then the take rate on the range extender would drop precipitously. This is where I think BMW swung and missed. They had the opportunity to put some distance between themselves and every other EV out there other than Tesla's products which are much more expensive. An i3 with an EPA range rating of 110  to 120 miles would have really created a new class of EV, instead they now have a premium version of a Volt combined with a LEAF. With electric cars, a lot of what's premium about the car is range and I'm a bit surprised BMW didn't get that message and offer slightly more range. They didn't need to match Tesla's long range vehicles though. If they just put some distance between themselves and the rest of the pack I think they would have hit a home run. I do believe the i3 will sell well, but it would have been much better received if it offered a slightly longer electric range.

My Model S for a day!
Then there is the Model S. A lot of recent news stories are comparing the i3 to it. Tesla's Model S is the benchmark that all other EVs, rightly or wrongly, will be compared to. That is because it's such a great car. However nothing offered today deserves to be compared to the Model S, it really stands alone at the top of he EV hierarchy. It's not only a great EV, it's great compared to just about anything. I don't like this comparison though, not because the i3 comes up short (literally), but because the least expensive Model S is nearly $30,000 more than an i3. In fact for what the least expensive Model S costs you could buy an i3 and a LEAF S and still have enough money left over to pay for the electricity to drive them both a combined 135,000 miles! Still, I understand why some people want to compare the i3 to the Model S. The i3 is the first EV coming from a "premium" auto manufacturer so they assume BMW was trying to go head to head with Tesla which they obviously weren't. The i3 may very well prove to be as good at what it was designed for as the Model S is at what it was designed for, but only time will tell.

I haven't seen anybody compare it to any of the low volume compliance cars currently being offered and I avoided using any of them here also. As compliance cars the manufacturers only goal is to get them leased or sold as quickly and as painlessly as possible and they can accept huge losses in doing so by heavily discounting them, offering unlimited mileage leases and even giving away free charging equipment. This is all great for the customer, but it doesn't allow a fair comparison.

I've seen a few people say it reminds them of an iMiEV and granted the stubby nose can draw some similarities to the shape, but having driven a few iMiEV's and have sat in a few i3's now I'd advise people to see and drive the i3 before you try to lump them together because they really aren't similar once you've seen the i3 in person. The i3 is more than a foot longer and 7 1/2 inches wider than an iMiEV and has much more interior volume, plus it has 40% more range and the performance isn't really comparable.

So while there is no perfect apples to apples comparison, I think the Chevy Volt is probably what makes sense the most to compare it to and that's only if you are comparing it to the i3 with range extender. However I believe the i3 is different enough that it's going to draw people that may not have bought a LEAF or a Volt, which is good for the plug-in industry. More choices will get more EV's on the road and as they say, a rising tide raises all boats.
