BMW i3 REx real world use

Today I got to experience the REx in the wild.  What I mean by that is I actually needed it.  I experienced the REx twice before but those were not when I needed it.  One was driving around town and letting the battery drain low enough for the REx to fire up because I wanted to see how it would perform.  The other time was a maintenance mode that the i3 runs during long periods of inactivity.

This time was different.  This would be about a 100 mile trip with 90% of it being highway and the car would be full of family and stuff.  Some might say 100 miles....maybe I could make it on electric alone, well nope.  With extra bodies it weighs the car down and the biggest draw is I would have to use the climate control so everyone was comfortable and I don't mean just a little ;) .

Off we go, I put the car in Eco Pro+ but of course right away I was asked to roll the windows up and turn the AC on so back to Eco Pro since in "+" mode there is no climate control.  On the highway I kept my speed to 65mph to extend the range as much as I could.  Things were looking good...I was driving well enough to do about 90 miles guessometer.  I was pretty pleased with myself and began to think of i3 REx EV masterfulness where I might actually reach 100 miles in EV mode.  Then one glitch, with about 30 miles left I pulled over to make another stop so the family could pick up some food.  I turned the car off for about 10 minutes.  Once everyone was back in the car I turned it on and range dropped to 20, I lost 10 miles just like that...I'll explain what happened there in just a moment.  With this event I really wished for that State of Charge (SOC) readout that for some reason BMW decided to remove from the US version.  Our ActiveEs had it and it was much easier to determine actual range.  This guessometer in the i3 is truly guessing.  BMW bring back the SOC, this is the ultimate driving machine not the ultimate guessing machine.

Ok...so those lost miles...as mentioned a few sentences earlier I parked, turned the car off for 10 mins then back on and noticed the guessometer showed 10 miles less.  I was not running the AC, doors were closed and it was not hot, so what gives.  Well it seems the navigation is tied to the guessometer.  During that 10 mins of parking I programmed in my final destination, the nav calculated hills and speed along the highway and adjusted.  Confirming this...umm feature....this morning I was on my way to Tom's i3 gathering and my range showed 92 miles...I punched in Tom's address, chose start navigation and right before my eyes the range dropped to 77.  Ok, now I stop navigation and we are back to 92 range.  Not really liking this, though I get what BMW is doing, with that said please let us disable this.  I looked and could not find a way to turn that off..bummer.  So here is a thought, if the nav says a shorter range but I turn it off and I have more range...will the REx stay off longer or will the guessometer adjust near the end....to be determined.

Nice of Serenity to warn me but I have a REx

I did take a look to see what would pop up and there we have Tom's

Back to the story.  As we drove along the miles ticked away, down to 4 left and 82 miles of electric the REx kicked in.  There was a slight vibration, I felt it because I was waiting for it, my family noticed nothing.  We were burning fuel, it just felt odd, I noticed no reduction in power and the AC ran fine.  I did notice the battery bar start to drop below 5% or at least best I could tell.  When that happened the little 2 cylinder revved up, now we all could hear it even on the highway.  It was not bad but it was there.  That little motor revved until the blue bar moved a bit right to reach the upside down grey triangle then it quieted down.  Each time that blue bar lowered it revved back up, it was working to maintain a level of between 5% and 7%.

Again the REx was not loud, when revved up you could feel it though not bad and keep in mind an EV has no vibration so everything feels enhanced, it was odd to hear a little put put going on from an EV.  Of course that sound is much better than the sound of my family complaining we are stranded.

Once off the highway the REx relaxed a bit and at stop signs or red lights turned off.  We did about 16 miles with the REx and my overall miles/kWh for the trip was 4.6.  Not bad for highway and AC running.

The red flag on the upper left means we won't make it on electricity alone

I probably could have made it with the pure electric i3 - it has slightly better range being lighter but it would have been white knuckle driving wondering if we would make it, I've done that before and it is no fun. Added I'd slow down and get off the highway and turn off the AC making the trip longer and less comfortable which my family would not be happy with.  There are no convenient public EVSEs along the route and that adds to the stress.  When winter arrives there would be absolutely no way I could have made it without the REx, the REx did its job, it added mobile convenience as well as peace of mind.

I took a whole half gallon and paid with cash

Do I wish the i3 had more battery range....of course...but it doesn't so the REx is a viable option.  It works and with that I will be driving my EV more which is a good thing, as well as letting my family take it out on runs.

EVolution: MiniE to ActiveE to i3

My introduction to EVs began back in the Summer of 2008 when I was lucky enough to be at an event with the AC Propulsion eBox, I even got a chance to drive it, though not very far or fast it was enough for me to realize EVs were something special.  As a car guy performance is key, after hours of rides in the eBox and a brief stint of driving it myself I wanted one, simple.

I got my chance the following year when the MiniE was offered as a field trial by BMW.  When the time came for me to grab one I did not hesitate.  I remember the day I picked it up at the dealer, there it was, just sitting there waiting to be driven.  It was a good looking package, subtle yellow plug graphics, a badge number and a slight hood bulge to clear the electronics underneath, the interior had attractive yellow highlights throughout.  I could not wait to turn it on and drive it.  I quickly signed the papers, grabbed the key, got in and started to roll away.  I was really careful at first, just eased out onto the street, after about 100 feet I floored it….whoa!!!!!!   200+HP and 160+ foot pounds of torque went to the front wheels and I was hanging on….absolutely an amazing silent rush of power, there was no turning back, EVs would now be in my future.  BMW did this one right, the aggressive regen and one pedal driving took about 30 seconds to adjust to and then it became instinct.  Imagine being in 1^st gear all day silently and no vibration, that’s what it’s like.  

As much fun as the MiniE was it had its faults.  The MiniE was truly a conversion, there was no back seat because that was where the 35 kWh battery sat.  Pop the hood and there was a golden box with wires here and there, we were warned not to take it through puddles or car washes….so what, this EV was still a blast to drive.  I loved surprising supposedly quick cars at the light, sure they could take me past 50 but under that I had the distinct advantage of instant power, no need to downshift and silent take off that confused minds.  Nothing felt cooler than stomping the juice pedal at 30mph, breaking the front tires loose and pulling away from the guy behind me in a rush of electrons. 

The MiniE was just raw, meaning it rode firmly, the heater was just adequate and the AC was so-so, not a lot of storage and this was not a car for long trips, even if you could find charging stations, it was a bit tiring to drive long ways.   

Best MiniE moment: I went to the dealer to get my plates and as I got out this guy ran up to me and said "Is that what I think it is, you actually got one?" He was talking on the cell and continued telling me he and his friends have been talking all about this car and never saw one, then he got back on the phone and said "Man you will never guess what I'm standing next to".

Next up was the BMW ActiveE.  This was the 2^nd phase of BMWs EV test program and it was a converted 1 series.  It took me just one brief test drive to realize this car was far more civilized than the MiniE, this one would drive on the highways comfortably.    The ActiveE was down on HP (170) but up on torque (184) and it was also up on weight, a whopping 4,000 pounds, but it was rear wheel drive which made it more sporty.  Fortunately the BMW engineers spent more time tweaking this ride and it drove extremely well for its heft, it glided along the roads effortlessly and you could push it hard in turns.  It felt like it was carved from a solid piece of metal as it had frame reinforcements throughout.  This added to the capabilities of the chassis, it took whatever you could give it.

With that said it was not as fast as the MiniE but much more refined and it handled like a BMW.  The EV also stood out, it had circuit graphics all over it which I really liked.  To help clear the battery up front there was an aggressive hood bulge which many 1M drivers asked how I got.  The interior was a light grey leather with blue highlights, very tasteful.  It also had BMWs iDrive system for gadget fun. 

Since the ActiveE was more of a of a drivers EV I took lots of long trips in the ActiveE, having a standard J1772 did not hurt, and its refinement meant I was not fatigued after a long trip.  I often did 80 miles or more and sometimes I did that daily for months….in the MiniE I probably would not have been as excited to do that.  In fact, in the two years I had the ActiveE I did over 30,000 miles, 80% of that in just over a year until my long commute changed, that is a lot of EV driving and it saved me $1,000s in gasoline costs.  The ActiveE actually became the main car for me and my family…my red sports car sat in the garage.  

Those graphics on the car made it a real stand-out, unmistakable that this was a special BMW.  Often I’d be approached or even followed, police too, so they could get a close look at it.  Folks in my town knew me by my car, I showed it wherever I could, it was an amazing experience all around.  Unfortunately the party has to end and the ActiveE will be going back.

Best ActiveE moment: driving to a Cars and Croissants, NJ exotic car meet, for the first time with my ActiveE and having 8 to 10 people running behind me before I even got a chance to park and talk to me about the car.

The ActiveE was a great car but there was something even better, worlds ahead, just around the corner, the BMW i3.

Admittedly when I first laid eyes on the i3 I was like…oh no way, how could they make it look like that, it does not scream BMW but econo-hatch.  Well over the weeks of seeing pictures and getting an up close and personal look at the car I began to like it more.  There are a lot of details, you just need to find them.  My last concern were those tires, talk about retro, like 1907 retro, those were some skinny tires, how in the world can this EV even ride on those.   I soon got a chance to find out and on a racetrack.   Yes a racetrack, BMW asked me if I’d be interested in riding around in the i3 on a racetrack with a professional race car driver…..ummmm let me think about that…OK!!

I won’t go into details of that racetrack day, you can read all about it on my blog www.myactivee.blogspot.com but I will say I was extremely impressed, as was the pro driver, Erin Crocker.

I can tell you the BMW i3 is indeed worlds ahead of the ActiveE and makes the MiniE feel like a soap box.  It is fast, it has the same power as the ActiveE but is over 1,000 pounds less in weight.   Other than being flung around in the i3 for hours at its limit I also got to drive it.  As soon as I pressed the accelerator I could tell this was a finely tuned EV, it just felt right.  The power is linear, the regen steps in seamlessly, the steering is connected to you and those brakes are incredible.  The i3 rides extremely well and yes, even with those skinny tires, it handles like it’s on rails.  The interior is roomier than you would expect and the carbon fiber details are really cool. 

Best i3 moment: track day….all of it

The i3 is packed with tech, from it’s cool features to the carbon fiber shell to the modern interior to its ability to hold the track.  I was seriously impressed.  Just one thing was missing, no hood bulge.

The EV had evolved into a seriously interesting daily performance driver in less than 5 years.  My Solar Orange BMW i3 REx will hopefully blend into this background very soon.
