2019 BMW i3, i3 REx, i3s & i3s REx: Full Specs

SEP 28 2018 BY MARK KANE 61

2019 BMW i3 – all the numbers in one tidy post.

Since the new 2019 BMW i3 was officially announced and it will be available in four versions – i3, i3 REx, i3s and i3s REx – here we gathered technical spec numbers for comparison. The main change is new battery cells (120 Ah versus previous 94 Ah), which in total stores 42.2 kWh (compared 33.2 kWh) within the same footprint.

The question is whether there still will be customers willing to buy the range-extender option as the new i3 will be able to go some 246 km (153 miles) in real-world driving.

Sales in Europe should begin in November/December.

2019 BMW i3/i3s specs and official chart (per BMW’s press release):

  • 42.2 kWh battery
  • 8 modules with 12 cells each (120 Ah lithium-ion cells)
  • Typical range 260 km (162 miles), expected EPA result of around 246 km (153 miles)
  • WLTP range : 285-310 km (177-193 miles) / 270-285 km (168-177 miles)
  • NEDC range : 359 km (223 miles) / 330-345 km (205-214 miles)
  • electric motors: 125 kW / 135 kW
  • 0-60 mph: 7.2 seconds / 6.8 seconds
  • 0-100 km/h: 7.3 seconds / 6.9 seconds
  • 80-120 km/h: 5.1 seconds / 4.3 seconds
  • on-board charger: 7.4 kW single-phase or 11 kW three-phase
  • DC fast charging: 0-80% in 42 minutes at 50 kW

Color me unimpressed.

Viking79

Really nice update, love my 2015 Rex, would be nice to have twice the electric range or more. Weight is starting to get too heavy though (300 lbs heavier than 60 Ah battery), especially given narrow tires, etc. The added weight has slowed it down a lot. As long as you get discounts BMW tends to offer it is a great car. This range update will make it even better.

Joel B

Any chance you could fit wider tires on it? I’ve heard the i3 tire size is a bit of an odd one, and sometimes it can be difficult to find new tires for it. Have you had that experience?

Will

They went to wider tires last year

Phel

Are they same size all around now? It’s stupid you cannot rotate the tires on an i3.

3laine

No, instead of 155/175 F/R, the i3S gets 175/195 F/R.

alohart

In earlier models, the base trim i3 BEV had the same size wheels and tires front and rear, so they could be rotated. Not sure whether that’s still true for later models.

tester

They went to wider tires, but they are still made only for this single car which means they are never kept in stock anywhere.

alohart

Only for the i3S. The i3 has the same tires as previous models.

Tony Marco

Tirerack.com

tester

Yes, the tires have gone completely out of stock before. I don’t how often that happens, but it HAS happened. The tires are by far my least favorite aspect of this car (I’ve owned 2 now).

John Doe

I’ve never had a problem with tires. They’re available at my local BMW dealer and the tire shop the company uses.
Probably because the car is so common here.

antrik

Yeah, the weight seems problematic: four adults in the REx version could easily get you above the permitted payload…

alohart

I’m guessing that the stated weight is based on the E.U. standard that includes a 75 kg (165 lb) driver.

wavelet

I was just about to comment on the low payload…
A 285kg / 627lbs payload (the REx version) is still less than 4 EU-measurement adults (==300kg), and is barely sufficient ever for 4 actual average European adults (71kg each) if they’re also wearing clothes (-;
Not to mention nothing left over for luggage. Very strange…

alohart

I suspect that the curb weight is based on the E.U. standard that includes a 75 kg (165 lb) driver. There’s no good reason why a 2019 i3 should be 300 lb heavier than a 2014-2016 i3. More energy-dense battery cells likely add some weight, but not 300 lb.

Will

Stil buying it with Rex since there’s a lot of areas with shaddy chargers and dead zones ( Texas) and mountain ranges that with a combine Rex can get you over especially when those ranges don’t have a DC( Pennsylvania)

Viking79

Exactly, also, this will drive down 90 Ah prices a bit, so with Rex, if you don’t really need 150 mile range, the 107 mile range of 90 Ah model might be good.

I have 60 Ah 2015 Rex, and DC fast charging has heavy taper after 80%. The 90 Ah has almost no taper until like 95% SoC, making it more useful. We don’t know about 120 Ah yet. The newer cars have refined a lot of the little issues too.

Driving over mountains, code it to unlock hold mode of course (unless you are within EV range).

Will

Are they going to uncode it since it’s pass the gas range

Viking79

The silly restriction will be there as long as BMW gets additional ZEV credits for BEVx (they get same credits as BEV instead of what a PHEV would get). BEVx says the car has to have less gas range than EV and operate at reduced performance on gas (to encourage charging).

However, being in Texas there is no issue coding the car to enable the hold feature as BMW is not getting ZEV credits for vehicles sold there anyway. Coding is essentially using a tool to replace some info in country specific config files in the computer system(s).

Will

Yeah I know that but the electric range is going to be double of Rex range, they should just leave like it’s built instead of changing it at the ports

dan

That restriction went away with the 2017s. The gas tank is only 2.3g.

Will

No. I’m taking about the hold mode

Viking79

They load config files onto the computer for each region’s laws. Unless CA eliminates BEVx requirements it won’t be able to access hold mode without coding it. The agreement was for BMW to get all BEV credits for a PHEV, it had to have less performance in Rex mode so they could make it a BEVx and not start engine until batteries run down. Hold mode specifically was designed to maintain performance while running on Rex.

I agree, they should let it run hold mode as designed, but it is what it is. At least it is easy to fix (presuming 2019 is as easy).

WARREN

You are right, very good taper characteristics on the 94ah. Even on a DCQC, my i3 can reach 99.t% SOC much quicker than the ABB charger anticipates. Hope the 120ah continues the trend.

Tony Marco

My 2014 i3 Rex will now be replaced. The extra range will make this the PERFECT city car (Including cold winter) for me with the Rex making it the PERFECT weekend traveler without having to worry about defective / busy charge stations.

Thx BMW !

Will

So the hold mode on the Rex with be on

3laine

No, unfortunately.

BEVx requirements include : “engine operation cannot occur until the battery charge has been depleted to the charge-sustaining lower limit”

So, no, they won’t let you turn it on at 75%.

Clive

You can code it to be that way if you’d like…

Will

Boooo.

Zzzoom

What about battery upgrade for older cars??

Will

Yelp they never brought that over here

3laine

BMW swapped a few 94Ah batteries into lease-return 60Ah cars and then sold them, but that’s as far as it went.

James

The spreadsheet says seating for 5. I’m pretty sure the seating capacity has remained unchanged at 4 seats.

Bob

Yeah, it looks like the interior is unchanged, and no where on BMW Blog or other information sites say there will be 5 seats….looks to be another case of sloppy research again….come on InsideEVs you are better than this!

BMW clearly says 5 seats, though perhaps the automaker messed up – https://www.press.bmwgroup.com/usa/oneclick/download/T0285420EN_US/attachment

Bob

My Bad then, it looks like BMW messed up…Please update your article with sources/references links next to your tables, otherwise it looks like you compiled the (incorrect) data yourself…

Pictures clearly show 4 seats: comment image

It may be an error. The image may be old. We don’t know. We’ve reached out to BMW to find out. I added the link, however, it is in the form of an attachment and a zip file, which most people won’t open or may have issues opening. With official press releases from the automaker, we don’t generally include the automaker link, partly for this reason. You can trust that we provide the correct information as stated by the automaker.

James

Thanks for looking into this Steven.

3laine

Pictures certainly still show 4 seats (with cupholders in the middle), not 5.

Davek

Bit of a shame that they didn’t take the opportunity to improve the DC charging speed. I’d almost have rather had 80 kW charging than the bigger battery, but that might be more difficult to achieve. Also fast charging would REALLY make the Rex obsolete.

dan

It would only save you a few minutes given the taper. This battery is too small to take in 80kW all the way to 80%.

antrik

That’s unlikely. Reportedly even the 33 kWh variant has no taper at 50 kW to way past 80%. Assuming the newer cells aren’t lower power, they could easily increase the charging power without much taper.

dan

The new battery has higher capacity, but is not necessarily rated for higher power. If they increased capacity by addding a few extra modules, what you say would be correct. Here, it is the same 96 cells, but each cell holds more juice. The current you can draw or send to the cell is probably not any higher and the voltage is also the same.

antrik

What I’m saying is that the 94 Ah cells seem to have a lot of reserve in terms of power — so unless the newer cells actually have a *lower* power rating, increasing charge speed should be no problem, at least for the cells…

Speculawyer

Given the not-so-great charging infrastructure in many parts of the USA, the Rex is still important for many.

3laine

Agreed. I was hoping for 100kW, which would be a little over “2C”, just like the original 22kWh battery at 50kW.

Viking79

My hunch is they are using more energy dense cells that might have a lower C rating so maintain same charge power.

dan

Exactly. BMW has generally been very conservative when it comes to cell health. My i3 hasn’t even lost 0.1 kWh of kapa max over 3 years. These are the best designed batteries on the planet. They aren’t going to trash the batteries just to save you an extra minute during charging.

antrik

If they have no visible degradation whatsoever, that just means there is probably a buffer hiding the actual capacity loss…

I’m sure though pretty much everyone would be willing to accept one or two percent capacity loss over three years in exchange for significantly faster charging, if there was actually such a trade-off.

antrik

I’m not sure I’d agree about faster charging *instead* of the bigger battery; but it certainly would have been welcome *along* with the bigger battery… It would have made longer trips more realistic without REx.

David Murray

I was a big fan of the Rex back when the i3 was first available. But, I have to admit as the range will now be 153 miles, I would probably pass on that option if I were buying a new one unless I planned to travel a lot. This is especially true since I just had to pay for my first oil-change on my Rex since it is out of warranty now. $253 for an oil change. On the bright side, it only needs one every year or two. But still, it’s ridiculous. But the bigger problem I see is that this new range still doesn’t make the i3 competitive with other EVs out there considering the price that BMW wants for the car. Luckily, I got mine used.

Tony Marco

I think most smart people bought one year lease returns for half price – That’s my story!

Dan F.

You can probably change the oil yourself for $25 or so, or is this a lost art.

David Murray

It’s a bit more difficult on an i3 Rex than other cars, that’s the main reason I took it to the dealer in the first place.

Speculawyer

Nice to see it improved a little bit. But we all know that BMW can do much better than this.

They are going to have a hell of time trying to sell this in any market where the Model 3 is available.

alohart

Two totally different vehicle categories. Many drivers, including me, prefer a light, nimble, raised compact hatchback (CUV?) over a heavy, low, large sedan. I would never consider buying any sedan, including a Model 3. I know that many others feel differently.

In August, BMW increased the i3’s daily production output to meet worldwide demand. It sells much better in markets outside of North America.

dan

Even in the US, the sedan is mostly a “single guy” car. Most women, married men, and dog owners of all persuations tend to prefer CUVs.

DS

So from this, can we assume the Mini EV will probably do a few more miles (as a result of better aero) but that 300km on a charge is out of the question? Because that’s really disappointing.

wavelet

I suspect the REx will be as popular as ever (IIRC, about half the i3 in the US have it) — 150mi range is decidedly mid-range, and making the car viable as a long-range car for $4K extra sounds like a decent deal (maybe they can even enlarge the fuel tank a bit & still have the car get the full EV credit?)

Bill Howland

I’m sure that BMW fans who can accept the Higher Price of a BMW product, will purchase both the new I3 and the I3 rex, since if you only have one car, you need SOME WAY of traveling, and renting a gasser all the time gets expensive and time-consuming.

I think they’d sell more if they put in a bigger gas tank than that trivial thing, since I’d hate the idea of having to carry a smelly gas can around. A car with an engine in it should be able to go 300 miles per fill-up.

That may be true the FIRST TIME, but circumstances may not permit recharging after the battery goes dead the first time.
