BMW Electric Cars: Past, Present And Future

NOV 20 2018 BY BRADLEY BERMAN 38

To understand BMW’s EV future, you need to understand its 45-year past.

It’s been more than a year since BMW’s chief executive announced that his company was making a wholesale shift to electric cars. Speaking in Munich in September 2017, CEO Harald Krueger told journalists, “By 2025, we will offer 25 electrified vehicles. Twelve will be fully electric.” A couple of months later, the company revealed that it had secured the naming rights for electric models across its entire vehicle lineup – from i1 to i9 for battery-powered passenger vehicles and from iX1 to iX9 for sports utility EVs of all sizes.

Krueger put a fine point on BMW’s transformation into an EV leader by saying that the company’s EV models could offer a driving range of more than 400 miles.

Future Target: 12 Pure Electric Cars and 13 Plug-in Hybrids by 2025

The BMW i4, due in 2021, could offer about 400 miles of range. The i4 is based on the BMW i Vision Dynamics Concept.

The 2017 announcement about BMW’s ambitious electrification goals is hardly a case of newfound EV religion. If the company hits its targets by 2025, it will be the culmination of BMW’s research and development into electric cars that started nearly five decades ago in the late 1960s. In one respect, the maker of the ultimate driving machine can be applauded for its diligence – taking one step after another across five generations of battery and electric powertrain technology to increase the driving range and performance of EVs. However, detractors see it instead as the Bavarian automaker repeatedly taking bold steps toward EVs with big promises and exciting concept models – only to make a hasty retreat to the combustion-based engineering that typifies its brand.

BMW is already one of the world’s biggest makers and sellers of electric cars. It’s on track in 2018 to sell 140,000 plug-in electric cars globally and by the end of 2019 is expected to have put more than a half-million EVs on the world’s roadways. Its global sales of electric cars and plug-in hybrids are up more than 40 percent so far this year. Those battery-powered vehicles represent more than 5 percent of the company’s total sales volume.


Past

At the 1972 Olympics in Munich, two orange BMW 1602 cars were used to support the marathon competition. The runners didn’t need to worry about breathing in noxious emissions because the 1602 was turned into the 1602e when engineers removed the sedan’s combustion engine and gas tank, replacing it with a dozen standard 12-volt lead-acid batteries. It was BMW’s first electric car, complete with a basic brake-regen system. However, it lacked a charging capability so the tray of batteries – 700 pounds’ worth – in the engine bay needed to be swapped out with fresh ones after getting depleted.

Development of the all-electric BMW 1602e started in 1969.

The 1602e was said to be capable of nearly 40 miles of range if driven steadily at about 30 miles per hour. But normal city driving meant less than 20 miles on a charge, not even enough to finish a marathon. BMW continued to work on EVs throughout the 1970s, revealing the LS Electric in 1975. As would become the pattern, it was one step forward and one step back. The LS used a new Bosch-supplied DC motor and a supposedly upgraded set of 10 lead-acid batteries. Alas, the LS Electric’s range and top speed were lower than its predecessor. A decade more of work resulted in an all-electric front-wheel-drive 3-Series converted from the all-wheel-drive conventional 325iX. The total of eight produced examples eventually wound up in the hands of German postal and government employees. The use of sodium-sulfur batteries pushed the driving range to an impressive 93 miles on a single charge. Not bad for the 1980s.

The all-electric BMW 325iX Electric, developed between 1987 and 1990, reportedly achieved 93 miles on a single charge.

Then came BMW’s first electric car built from the ground as an EV. The 1991 BMW E1 is often cited as the predecessor to the current i3. The E1, a city-oriented four-passenger EV, was capable of about 125 miles per charge. Like the i3 that would arrive two decades later, the E1’s body was built from exotic materials, which were aluminum and recycled plastic in the E1’s day. The next generation of the model was dubbed the E2 at the 1992 Los Angeles Auto Show. Despite positive buzz and construction of about 25 more vehicles built using 3-Series coupes in the 1990s, BMW stayed on the electric sidelines – and remained quiet even in the subsequent decade when GM made (and killed the EV1) and the Toyota Prius gas-electric became an international phenomenon.

The 1991 BMW E1 was the company’s first purpose-built all-electric car.

Then, in June 2009, BMW shook things up when it established a program to lease 450 MINI coupes converted to run on electricity. About 600 of the cars the electric MINIs were produced. Leaseholders in Los Angeles and the New York/New Jersey area paid $850 a month – including insurance, maintenance, and a home charger – to drive the MINI-E for a year. Most of those 450 guineas pigs, the first consumers to drive BMW-produced EVs, fell in love with the car despite sacrificing the entire trunk to make room for a 35 kilowatt-hour battery pack that delivered more than 100 miles of real-world range.

Stating in 2009, BMW allowed hundreds of customers to lease the all-electric MINI-E.

The MINI E, and the follow-up 1-Series rear-wheel-drive ActiveE , were decisive steps forward for what BMW called its Megacity Project – the creation of a quick and capable small electric car intended for the world’s crowded urban roadways. Those Megacity testing prototypes would become the foundation for Project i and the development of the i3, i8, and the BMW electric cars that continue to roll out today.

The list of upcoming models includes the all-electric BMW iX3 crossover due in 2020. Its expected to get 250-plus miles on a single charge. The BMW i4 sedan planned for 2021 could offer about 400 miles of range. And the super-futuristic iNext, a platform for autonomous driving, could get an even bigger battery.

Present

By circa 2010, BMW appeared ready to take a leadership role in electric cars. Its approach was not merely to make a practical and appealing electric car but to embody all the transformations needed for urban mobility in the 21st century. BMW engineers created something called LifeDrive, a lightweight body shell made from carbon fiber reinforced plastic. Manufacturing a new type of EV would take place in Leipzig, Germany using a preponderance of wind-derived energy.

BMW’s LifeDrive carbon fiber platform.

The unveiled design of the i3 compact – and the i8 plug-in hybrid supercar to a lesser extent – was iconoclastic. The i3’s visual lines seem inspired by Cubism. The car appears to lack a B-pillar as the front and rear doors overlap to form a structural pillar. It employs a barn door design for access to the back seats. Its sleek Bauhaus dashboard design used open-pore eucalyptus wood, hibiscus-like kenaf, and hemp – which critics suspected BMW was smoking when coming up with its over-the-top artsy, intellectual approach that undermined the brand’s sports car heritage.

The problem went beyond aesthetics. The fancy materials added cost. By the time it got driven off the lot, the i3 commonly cost more than $50,000 – for a car that, when launched in 2013, only granted 81 miles on a charge. That was less range than BMW’s experimental models. The company tried to make up for the i3’s range deficiencies by using a tiny, loud 650cc backup gas-powered engine to extend its range another 80 or so miles until drivers could find a charge.

BMW i3

Nonetheless, the i3 earned its share of fans, hitting a peak in sales in 2015, its second full year of sales in the US. In that year, BMW sold 11,024 i3s. Since then, sales declined to 7,625 and 6,276 cars in 2016 and 2017, respectively – even as the size of the battery increased to allow for 114 miles of range in 2017. While the next i3 is expected to utilize a 42.2-kWh pack providing 150 miles of range, BMW executives admitted in April 2018 that the company might not invest in future, redesigned versions of the i3. The range-extending option was discontinued in Europe.

Electric mobility will become standard. It will become normal,” said BMW design director Adrian van Hooydonk.

Lessons learned, BMW is turning its focus to future EVs that look less weird. “I think in the next years, electric mobility will become standard. It will become normal,” said BMW design director Adrian van Hooydonk in an October 2018 interview with Auto Express. “It will become just one of those powertrains that you can choose. And that will probably lead to the customers not necessarily wanting a design differentiation.”


Future

So the BMW electric car will start to look more like the company’s other vehicles. And, if Robert Irlinger, head of BMW’s i division, gets his way, the range will also be similar. “The starting point for i3 in the early days was okay. But it seems that now, 300 kilometers (186 miles) is the minimum that you can offer to have an accepted range for customers.” He added that some customers want as much as 400 miles on a single charge.

A new version of the MINI-E with about 200 miles of range is due in late 2019.

That explains why the upcoming, new version of the MINI-E, due in late 2019, is expected to have at least 200 miles of range. It also sheds light on why the new plug-in hybrid powertrains coming soon to nearly every sedan and SUV in a BMW dealership showroom will have an all-electric range between about 30 and 50 miles before they resort to using gasoline. And it’s why the iX3 due in 2020 will get 250-plus miles on a single charge, while the 2021 i4 could push the range envelope to about 400 miles.

BMW is talking about broadly rolling out EVs with three different battery choices: 60 kWh, 90 kWh, and a mammoth 120-kWh pack. The menu of BMW’s in-house electric motors could range from 100 kW (135 horsepower) to more than 300 kW (400 ponies). These variants would be installed on the same production lines producing combustion vehicles rather exclusively at special turbine-powered facilities.

Hurry Up and Wait

With more BMW EVs getting announced than anybody can reasonably keep track of, perhaps we are getting ahead of ourselves – as BMW is prone to do with its electric car ideas. EV fans might be cheering BMW’s plans for a big EV future, but the company’s bean counters are hitting the friction brakes.

“If you want to win the race, you must be the most cost-competitive in the segment,” said Krueger.

Klaus Frolich, the 58-year-old BMW board member in charge of development, in October 2018 said, “In EVs with 90- to 100-kWh battery packs, the cell cost alone will be $17,000 to $25,000. You can produce whole cars only with the cost of the battery.” Frolich cautioned that by 2030 only about 15 percent of BMW’s portfolio would likely be pure electric.

BMW i Vision Dynamics and Harald Kruger, chairman of the board of management for BMW.

And CEO Harald Kruger, the same leader who proclaimed a bright new day for BMW EVs in 2017 sounded less bullish on EVs six months later in March 2018. That’s when he said BMW could not scale up production with its current generation of battery-electric technology.  “We want to wait for the fifth generation to be much more cost-competitive,’ said Krüger. “If you want to win the race, you must be the most cost-competitive in the segment.” Meanwhile, BMW is already working on the sixth-generation of its EV and battery technology. The company said it was investing about a couple hundred million dollars to better understand how to mass produce EVs – some day.

Minor nit: the i3 REx engine is 0.65 l, not 1.0 l as stated in the article.

IQ130

BMW EV with the Longest Electric Range is now the BMW i3 (120 Ah) with 153 Miles

https://www.fueleconomy.gov/feg/Find.do?action=sbs&id=41054

scott

120 Ah? That’s meaningless. Use kWh.

Big Solar

i think its 44 KWh or there about

DS

Has there been any confirmed details of the Mini’s range? All we know is that it won’t use next gen drivetrains, which BMW is saving for the next i3. That’s pretty shit IMO, we’ve been waiting a long time for an electric Mini and we end up with last week’s components?

dan

Not the next i3 (there may not be one). The 5th gen powertrain will be on the iX3 in 2020.

BEVfan

Even with the actual drivetrain, the i3 is one of the most efficient EVs.

antrik

Seems the newest variant is pretty much on par with the LEAF? Which isn’t terrible, but far from the most efficient…

Jack

True, but it is so much better as a driver’s car than the Leaf.

I imagine that BMW is understating the range as they do in the current 94ah version. I have to try pretty hard to only get the rated 115 miles of range. It’s more like 135 in mixed driving in my 2018.

wavelet

Very nice article! I wasn’t aware of BMW’s earlier EV history, and a retrospective like this is very useful.
I also like the balanced attitude — the article pointing out that BMW isn’t speaking with a single voice on EVs, and that some top execs aren’t quite bullish on the rate of progress.

Clive

I guess GM somewhat copied BMW’s E1 naming when they named the EV1

DS

Some of that could be the political climate in Germany when it comes to actually being able to deliver on EV promises. We’re seeing different approaches from *ahen* ‘other’ manufacturers.

wavelet

Maybe, but every human organization has internal politics (which literally means “affairs of the community”, after all ), and I think simple differences of opinion explain it — even among execs who fully believe in electrification there might be disagreement on the pace.
I’m mostly concerned with the tiny-AER PHEVs (anything below 20mi or so), which I think might be more damaging environmentally than straight ICE vehicles.
The current crop of such cars is somewhat understandable — it’s the cheapest in terms of both design effort (conversion vs. clean slate) and battery resources. Bit if we see BMW and others continuing to make them, rather than doing Volt-type ranges, that’s a problem.

phEVfan

“[customer demand for more range] also sheds light on why the new plug-in hybrid powertrains coming soon to nearly every sedan and SUV in a BMW dealership showroom will have an all-electric range between about 30 and 50 miles before they resort to using gasoline.”

No, the reason the new powertrains have minimum 31 miles is the new 2020 European regulations that require 50km (31 miles) minimum. It’s called compliance.

Chris S

I can’t find any 50km threshold you are speaking of in EU policies. There is a fleet emission target of 95 grams CO2/km and extra credits for <50g/km. There are other incentives, but those are national.

AlexanderL

A German law (“Gesetz zur Bevorrechtigung der Verwendung elektrisch betriebener Fahrzeuge (Elektromobilitätsgesetz – EmoG)”) defines that only hybrids with either <50gCO2/km or at least 40km of electric range qualify for incentives, including a new tax regulation for company paid but privatly used cars that is important for the german market.

wavelet

Yes, do you have a source? IIRC the UK now has a 70mi (110km) minimum for customer incentives, but that’s not a regulatory limit on the carmakers.

CU

Chinese requirement

Ravilyn Sanders

Waited eagerly for the i3. Was excited about the range extender limp home motor. Then ….

BMW came out with a car that looked like it was designed by Mattel or Fisher Price for toddlers…

windbourne

wow.
I have not been the least bit impressed with the garbage coming out of legacy car makers.
Jags garbage is just that: garbage.
However, it looks like things are starting to finally change.
The i4 and i vision dynamics looks good.
VW’s visions (I forget what it was called), was looking interesting.

What is coming next year, is not going to give Tesla a run for their money.
BUT, it appears what is coming AFTER (i.e. late 2020) MAY finally do it.

antrik
There is more to it than what the article mentions. Don’t know how much of that can be confirmed by other sources: but when talking about the i3 after his teardown, Sandy Munro pointed out that the car was designed to optimise costs for a low production run of 30,000 or maybe 50,000 cars total. Supposedly they were working on a different design, that would offer better costs at a run of 100,000 or more, for an upcoming i5 hydrogen fuel cell vehicle. This seems very plausible, since it would explain why BMW was willing to invest so much money in a program that yielded just niche results: apparently the real focus was on an expected big hydrogen future, with the i3 and i8 pretty much being just byproducts. It seems that BMW soon realised that this future was not coming to pass, and started writing off the investments and more or less winding down the entire project — as witnessed by a huge exodus of managers and engineers in several waves (some going on to create Byton; others joining Faraday Future etc.); as well as remarks in 2015 or so that the “i” brand would now be focusing primarily… Read more »

Interesting; I hadn’t seen that info/analysis. What I had heard was that BMW management was quite disappointed with the i3’s sales numbers (although this is of course never mentioned in the PRs), and expected sales about twice as high as they are, in most markets; that led to a big internal debate on whether to continue the i5 program at all (reportedly a 5-series sized BEV) . They have to continue doing the PHEVs no matter what to comply with EU emissions.

Will

Info and sources. If it was such s money put then they should have discontinued the i products. They already have Phev to get the credits

scott

Put a 60 kWh lithium battery in that 1991 325ix and I’ll take it.

Vexar

Just don’t forget these words from the article:
“BMW stayed on the electric sidelines”
I think that’s all that needs to be said here. What everyone cares about is volume sales. I like that the Jaguar iPace is 10% of sales already. I think that’s meaningful. I’d love to see BMW have 10% of its sales as a BEV. I dream, of course.

dan

Other than the fact that BMW sells more cars in a week than Jaguar does in a year. You say everybody cares about volume sales, but you forget the most basic math that pertains to volumes – the volume!

antrik

That doesn’t make it a smaller commitment for Jaguar…

Dan F.

Not true. Substitute a month for a week and you will be roughly correct. BMW is a small automaker (2.5 million including mini and Rolls Royce) but made roughly $10B in 2017. Jaguar (owned by Tata of India) sells roughly 10% as many vehicles

rey

BMW,,How is your future going to be secured by the tag line “Ultimate driving machine” when people are going to be driven autonomously? “Ultimate Robot Machine”?

antrik

Ultimate self-driving machine?… 😉

Will

50 years away. They can worry about it then

Clive

To slow.

Well hopefully BMW will speed things up when he retires in less than 2 years from now.

Gyro

A really interesting article, and well-researched. I luv my i3 bev, with it’s 18kWh, but I’d be even more impressed if I owned the new 42kWh model. It is a beautiful EV solution. “Beauty is in the eye of the beholder.”

REXisKing

Consumer Reports rates the BMW i3 2017 5/5 Star: Reliability.
That should relieve some concern about the car.

jim stack

The biggest jump for BMW was the converted MINI-E by ACPROPULSION of San Dimas California. ACP also did the T-Zero that Tesla used to start their company and they did others to show Lithium batteries and AC Motor and Controller were best. They also determined the Lithium laptop cells 18650 were lowest cost and best for cooling and lasting a long time.

QUOTE=Then, in June 2009, BMW shook things up when it established a program to lease 450 MINI coupes converted to run on electricity. About 600 of the cars the electric MINIs were produced.

Bob Wilson

I have a 2014 BMW i3-REx and around town, great. But cross country charging using EVgo and VW’s Electrify America costs four times over gas. Charging is significantly slower, 30 min, than refilling the ~2 gal tank, 5 min.

Sometimes chargers are broken or busy and with the REx, I continue my trip. Coded for EU standards, the car would be more practical with a larger tank or more efficient engine. It will maintain 70 mph (112 kph) without dipping into the battery but more REx charging to sustain 75 mph (120 kph) would be great. Still, it easily follows trucks and trailers easily.
