In a recent market survey undertaken by members of my immediate family, I discovered that not all aesthetic values are genetically inherited. Rather than being sad, this insight has given me the opportunity to explore new vistas. If people are not interested in revisiting sardine roles, sitting in a mini-van for days or weeks at a time, meditating on the spruce trees of Northern Sweden, I too can abandon the mini-van, and opt for something that reflects my new essence – the workshop activist.
So it is going to be, Au revoir, Berlingo! Hi, Bison! (or if I follow up what I wrote a few weeks ago, Hallo, StreetScooter Work!)
I have had relationships with pickups before. The very first vehicle I drove, in the very early 1960s, aged about twelve, was a Chevrolet Pickup belonging to Harry Raymer, in some fields in Okanagan Mission, near Kelowna, British Columbia, Canada. Later, in the early 1970s, I drove Ernie Jickles – whose eyesight was failing and was not allowed to drive – around in his wife’s Ford Courier pickup, so we could photograph. The Courier was a rebadged Mazda B-1800. In the late 1980s, in Inderøy, I drove a Nissan pickup working on a lafted house project out in Malm.

Forget the past. Today’s story is set in the future, about the Bison, a Dutch-Canadian electric pickup. The primary characteristic it attempts to portray is rugged durability. That’s almost how I describe myself, as do about 90% of the adult male population.
I’m not sure if it is a corporate, or a product motto, but LEADING THE CHARGE™ has both electrical, and military connotations. It also describes itself in terms of three other characteristics: power, precision, strength.
Characteristics of the Bison pickup, I think I understand:
1300 liters of exterior cargo space and 510 liters of lockable storage. Safest truck with carbon fibre reinforced steel space frame. Full electric AWD built for severe weather conditions. High-current power socket for all your tools. Advanced vehicle intelligence and connectivity. Zero emission driving and zero pollution. Dual-motor electric powertrain. Advanced telemetry.
Characteristics, I know nothing about:
Rugged off-road capabilities with 54% hill start and 21% hill climb. I guess this is important, because I live on a hill, but have no idea what it means beyond being able to start off on a hill. Yes, I am too lazy to google it.
Somewhere in between: Class-leading torsional stiffness for enhanced durability and handling. I know what stiffness is, but I thought one invested in a suspension system in trucks to softened up that stiffness.
I would like a person, or even a designer, to read the following paragraph, and tell me that it actually means something that I can use to impress friends: “The Bison speaks a bold design language, punctuated with angular cladding and wedge profiles. An evolutionary leap forward from traditional pickups, the Bison delivers a more modern and provocative approach. With short overhangs and tires pushed to the corners, the stance conveys stability and confidence allowing for aggressive approach and departure angles.”

Back in 2014, I outlined an electric vehicle, Trell, that could be made by inmates at Verdal prison, where I worked teaching technology and associated subjects. Trell was mainly a pedagogical vehicle, but if actually built, could be used to solve a number of transportation challenges at the prison. A blog post on the original Trell will be published in the future.
The Present
Now it is 2018, and I see a need for an battery electric autonomous truck emerging.
Let’s begin by qualifying that statement, by examining it word by word.
Battery: While a battery may be needed for last kilometer situations, there is no reason why electric vehicles have to store significant quantities of energy onboard. It only adds to vehicle weight which increases capital and operating costs. The term dynamic wireless charging is often used.
Electric: This vehicle will be electric powered. Electric motors are preferred because they generate maximum torque even while stopped.
Autonomous: All contact with the vehicle will be through electronic devices sending and receiving encrypted messages. This vehicle will not require a driver. In fact, there is no space on board for a driver. Using the Society of Automotive Engineers’ levels for automated driving systems this vehicle will have to be at either level 4 or level 5. At level 4 vehicles are “designed to perform all safety-critical driving functions and monitor roadway conditions for an entire trip.” It is limited to the operational design domain (ODD) of the vehicle, which is an incomplete set of driving situations. At level 5 this ODD restriction is removed and the vehicle’s performance to expected to equal that of a human driver, in every driving situation including extreme environments, like snow covered roads.
At this prototype stage there is no need for a functioning autonomous vehicle. Many prototypes lack drive trains entirely. A compromise will be fitting the vehicle with remote control equipment, so that the entire movement of the vehicle is under the control of a living human being.
Truck: This vehicle is to be used for the shipment of goods. Minimum cargo capacity is arbitrarily set to LxWxH 2 500 mm x 1 250 mm x 1 000 mm. No people will be transported under any circumstances.
Conceptual sketch of a Trell 2 Battery Electric Autonomous Truck
The Trell 2 is inspired by the Subaru Sambar more than any other vehicle. The vehicle is designed to transport bulky materials. Target materials are plywood and other construction material sheets. This would require a vehicle design width of 1 600 mm, which includes 50 mm on each side for side doors that open upwards into the roof. The doors would be 2 500 mm long and 1 000 mm high. The vehicle would have a length of 3 500 mm of which 2 500 mm would dedicated to cargo. This is fitted with one door along each side. At both ends of the vehicle 500 mm is used to make an aerodynamic front and rear end. Most of this volume would also be available for transporting goods.
The Future
This is far too big a project for me to work on alone. Or more correctly, I have so many other projects that I am interested in, I can’t devote all of my energies to a time thief like this. However, I see it as an opportunity to work with several others at the new Hastighet = Velocity workshop in Straumen.
The first recruitment session will be at the annual meeting of the local Friends of the Earth group, at the end of February. Once vehicle specifications have been agreed upon, I imagine a prototype could be built using components from scrapped vehicles. EVs for drive train components, smaller pickups (such as a Subaru Sambar) could provide many useful parts.

Volkswagen AG, much like this van, is no longer fit for purpose. Photo by Sean Maynard 2009-08-04 at Tofino Botanical Gardens.
I was looking forward to driving (if not owning) an electric Volkswagen Buzz. This is no longer the case. I can no longer support the immorality of Volkswagen. Volkswagen AG is no longer fit for purpose.
First, there is the Dieselgate scandal involving 11 million cars that produced more NOx pollution than authorized, harming human health and killing thousands. Volkswagen’s actions were clearly immoral.
Second, Volkswagen lead experiments on 10 macaque monkeys to test the health impact of exposure to nitrogen dioxide (NO2) in 2014. Again, Volkswagen’s actions were clearly immoral.
Third, Volkswagen partially funded an automotive lobby group that tested the effects of NO2 exposure on 25 healthy young people. This was in 2015. For yet a third time, Volkswagen’s actions were immoral. At this revelation, I have reached my breaking point.
In Europe, Volkswagen is not paying fines, and executives do not seem to be going to prison. So, if government cannot be trusted to punish Volkswagen, at least to the extent of the damage it has deliberately caused, then consumers will have to take matters into their own hands.
Volkswagen will have to be boycotted for at least ten years. The start date for this ten years should be the last date when illegal/ immoral behaviour was revealed. At the moment this means a boycott at least until January 2028.
Volkswagen probably should have been dissolved as a company, and had its assets impounded.
Enter Streetscooter!
Consumers are not the only ones annoyed at Volkswagen, but for different reasons, although perhaps both are grounded in Volkswagen’s arrogance. Much to the annoyance of Volkswagen, Deutsche Post has designed and built its own electric delivery van.
These vehicles allow Deutsche Post to meet demand for e-commerce deliveries without adding to air pollution in German cities. They also replace conventional Volkswagen vans.
Deutsche Post became a manufacturer when conventional vehicle makers turned down requests to build electric delivery vans, in limited numbers by automotive sales standards.
Volkswagen CEO Matthias Mueller is quoted as saying, “I am annoyed beyond measure. I, of course, ask myself why Post did not talk to our VW Commercial vehicles division about doing something similar.” Unfortunately, that comment misses the truth, Volkswagen were asked, but declined.
Deutsche Post bought electric-vehicle manufacturer StreetScooter in 2014, where they use over 5 000 vans and 2 200 bicycles (and tricycles). The goal is to operate only battery-powered models. In addition StreetScooter is about to sell products to third parties, like bakeries and airports.
Advances in CAM allow almost anyone to use potential parts suppliers to design, engineer and test new vehicle concepts. There is no need for a large staff of engineers, or invests in tooling and factories. This transition by first undertaken by brand name automotive companies to keep their own costs down after the global financial crisis, starting ten years ago in 2008. They farmed out research and development relating to parts and sub-assemblies. Thus, it is not the brand names that own technical and engineering expertise, but increasingly a network of suppliers. In 2018, these produce components that constitute 80 percent of a vehicle. This contrasts with about 56 percent 30 years earlier. This is a perfect situation for new entrants, such as Google and Streetscooter.
Win Neidlinger, director of business development at Streetscooter GmbH, told Reuters, “We are purposely not reinventing the wheel. We do not produce a single component ourselves. Everything comes from a supplier.”
Parametric Technology Corporation is a bit difficult to say, so it is a good thing that they have changed their name to PTC. Windchill software, made by PTC, costs 300 to 1,000 euros per user per year. It is used by 90 percent of the top 50 automotive companies. It is also used by Streetscooter to communicate with a network of 80 suppliers.
Software systems are becoming more accessible, because automakers, after spending years and millions to customize in-house development programs, have begun switching to standard systems. This is necessary to access their network of suppliers. Open architecture, interfaces and standards have all become part of an industry launched code of conduct for product lifecycle management.
Deutsche Post knew that with increasing e-commerce orders, increased inner city delivery trips would mean increased pollution, unless it switched to zero-emission vehicles.
Electric vehicles are simpler in design than internal combustion engine cars require only 10% of production staff during assembly. This dramatically lowers production costs. Neidlinger adds, “We designed it as a tool. So the fit and finish does not need to be as good as in a passenger car.” The vans are designed to last 16 years, operate six days a week, for 10 hours at a time. Some components need to be particularly robust. Doors are expected to be opened and closed 200 times a day.
The StreetScooter Work introduced in 2015 is equipped with 20.6 kW /h lithium-ion battery packs and is powered by asynchronous electric motors, The peak/continuous output is stated as 48 /38 kW and 130 Nm of torque. The range is said to be 118 km (NEFZ) or 80 km (Deutsche Post approved), but this depends on the load weight, traffic and environmental conditions. This distance is possibly adequate in inner cities, but little short for use in rural areas. Charging to 80 percent takes 4.5 hours, a full charge takes 7 hours, using a Schuko socket with 230 V and 16 A maximum. The load capacity is 710 kg. Internal cargo volume is 4.3 cubic meters. The body structure is made of steel and the exterior panels are made of structural plastics. Its unladen weight is 1 420 kg, with a total weight of 2 130 kg. It is fitted with ABS brakes and has a driver’s airbag. Dimensions L/B/H of the pickup version in mm are: 4 649 / 1 805 / 1 840. Deutsche Post board member Juergen Gerdes told Reuters, “It did not cost billions to develop and produce. You will not believe how cheap it is to make.”
With a vehicle like this Streetscooter Work pickup, I could enter the world of real men, but in an environmentally more sustainable way. Of course, real sustainable people don’t buy vehicles. This vehicle is in my preferred colour. (Photo: http://www.spijkstaal.nl/)
Compared to a Volkswagen Caddy that this vehicle replaces, there is an environmental saving of 3 tons of CO2 per year. With electric motors the total cost of ownership is no more expensive than an equivalent ICE van.
In September 2016, Deutsche Post presented a larger version, designated StreetScooter Work L, which has 8 cubic meters of space to carry up to 150 parcels weighing a total of 1,000 kg.
Enter Ford!
In July 2017 serial production started in Aachen for Work XL, based on a Ford Transit. Batteries are modular, between 30 and 90 kWh, given a range of between 80 and 200 kilometers. The charging time is around three hours at 22 kWh. Plans are to produce 2 500 electric vehicles. This would save 12 500 tonnes of CO² and 4.75 million liters of diesel. The Work XL has 20 cubic meters of cargo space for over 200 parcels.
The production of these vehicles makes Deutsche Post and Ford the largest producer of battery electric medium-heavy delivery vehicles in Europe. “I regard this partnership as a further important impetus for electric mobility in Germany,” says Jürgen Gerdes. “The move underscores Deutsche Post’s innovation leadership, it will relieve the inner cities and improve people’s quality of life, and we will continue to work on completely CO2-neutral logistics!”
Ford is probably the best placed company to work with Deutsche Post. First, the Work does not threaten Ford’s F-series of light and medium duty vehicles, which are the best selling models in both the United States and Canada. It doesn’t threaten the Ranger series either, although if the Work proves successful, there could be lost sales, here. Second, an electric Work would supplement Ford’s offerings, and attract new, electric oriented buyers.
Third, delivery vehicles are especially important for their signal effect. These are seen by the public daily. There are five positive characteristics that the Work can signal: a) range confidence; b) low operating costs; c) durability; d) operator safety; and e) environmental suitability.
I will end this post with an appeal to any readers who have connections with Ford. If Ford wants someone to evaluate the suitability of a Work in Scandinavia I would happily volunteer, especially if I could get the vehicle at reduced price. Yes, there should be seating for three, with each given appropriate airbags. Yes, it should be able to pull a 1 200 kg trailer.
Weiss, Richard (24 March 2017), “Even Germany’s Post Office Is Building an Electric Car”. Bloomberg. “Even Germany’s Post Office Is Building an Electric Car. When Deutsche Post AG couldn’t find a zero-emission delivery van that met its needs, it bought a startup and developed one. Now Europe’s largest postal service may start selling those vehicles—dubbed StreetScooters—to others, showing the potential for disruption in the rapidly changing auto market.”

What right does an individual have to be transported in an inefficient and heavy pod? This, and other strategic questions, are ignored in discussions about electric vehicles. Debate focuses on narrow tactical issues, rather than those of strategic importance.
Yes, vehicles are necessary, but not all vehicles are necessary. Electrification of vehicles is a necessary transition if the world is to avoid the calamity of global warming. Unfortunately, it is probably an insufficient measure. This means that very shortly one must come back to the initial question about individual rights.
Nations and Cities
Much of the debate about electric vehicles has been left to vehicle manufacturers, who have a vested interest in the status quo. EV1 developed by General Motors was a pubic relations dream. Everything about the EV1 was orchestrated to show the impracticality of EVs, except for the fact that the consumers who used them loved them. In the end, GM used all means at its disposal to destroy all vestiges of the EV1. They didn’t succeed.
General Motors EV1 the iconic electric car loved by everyone except its maker who tried to exterminate every EV1 made, and largely succeeded.
While vehicle manufacturers have their own particular strategies, these will have to be harmonized with those of nations and cities where EVs will be operated. California requires manufacturers to sell EVs in order for them to be allowed to sell environmentally dangerous vehicles. They do so at a loss. Both Norway and the Netherlands have stated that they will not allow the sale of new fossil fuel vehicles after 2025 and 2030, respectively. Many other nations are talking about 2040. The Paris Accord may force these and other nations to react before then.
Consumers
It would be easy to be a vehicle manufacturer, if one could ignore customer needs and desires. Unfortunately, vehicles still have to be sold. This means that consumers are concerned with such matters as net acquisition costs, that is the cost of a vehicle after any government subsidies have been taken into consideration, and operating costs, especially the price differential between gasoline or diesel and electricity.
This said, a mid 21st century consumer may not be a private individual. It may be a ride-share company or other consortium of investors. The riders in that vehicle may not just consist of a vehicle owner and her immediate family.
Types of vehicles
With a little good will, there are six types of motive power in use. ICEV = internal combustion engine vehicles, found in two variants, gasoline and diesel. In addition, there are: HEV = hybrid electric vehicles, PHEV = plug-in hybrid electric vehicles, BEV = battery electric vehicles, and FCV = fuel cell vehicles.
Unfortunately, there is no reason why any of these variants should exist in 2040. WPTEV = wireless power transfer electric vehicles, are the future, especially if they are equipped with auxiliary batteries for “last kilometer” use, and as a safeguard against grid disruptions. In the future, the term hybrid may designate a WPTEV equipped with a battery.
Market segment
The European Union has divided the automotive market into nine segments, referred to by as single letter. These are (with 2011’s market share followed by 2015’s in parenthesis, to closest tenth of a percent) – A: mini cars (8.7/8.8); B: small cars (26/22); C: medium cars (23/20.6); D: large cars (11/9); E: executive cars (3/2.7); F: luxury cars (0.3/0.3);J: sport utility cars (including off-road vehicles) (13/22.5); M: Multi purpose cars (13/10.5); and, S: Sports cars (1/0.7). This leaves (1/2.8) not reported. While other segments show some change, SUVs have almost doubled in quantity. This trend was not noticed in Norway, perhaps because SUVs have already been overrepresented. Further information is found here.
While some electric vehicles target luxury segments, many are for the 99%, segments especially A to C. Low-speed neighbourhood vehicles are largely electric. A large number highway speed A-segment vehicles are found, including the Fiat 500e, VW e-Up and Smart ED. Only a few B-segment vehicles, such as the Renault Zöe, are battery electric. Choice is further restricted in the C-segment, which is dominated by the Nissan Leaf. The Tesla Model S is in either E or F. J-segment SUVs, such as the Hyundai Kona, are just coming onto the market. The Workhorse W-15 pickup prototype, indicates that electric vehicles may soon enter this market segment.
Manufacturing strategy
Automotive manufacturers tend to concentrate on what they perceive to be their core competencies. They insource everything from electrical components to car interiors from specialist manufacturers, such as Bosch (electrics) and Faurecia (interiors).
Strategic decisions have to be made regarding manufacturing platforms, as well as product design
Platforms
There are two approaches to platforms to produce electric vehicles. Either one can produce battery electric vehicles on existing platforms, or design a completely new platform for electric vehicles.
Product design
There are, similarly, two approaches to electric vehicle product design. Either one can adapt battery electric vehicles to existing ICE designs, or design a completely new product. While an adapted battery electric vehicle could be produced on either type of platform, a new electric vehicle design would almost certainly require the use of a new electric vehicle platform.
Case study # 1 – Fiat-Chrysler
Fiat-Chrysler CEO Sergio Marchionne is an EV skeptic. In November 2009, he disbanded Chrysler’s electric vehicle engineering team and dropped sales targets for battery-powered cars, that had been set as it was approaching bankruptcy and needing government aid. Its electric car program had been part of the case for a USD 12.5 billion federal aid package.
As late as August 2009, Chrysler took $70 million in grants from the U.S. Department of Energy to develop a test fleet of 220 hybrid pickup trucks and minivans. Chrysler’s previous owner, Cerberus Capital Management, had set up a special division in 2007 called “Envi” as in, environment, to develop hybrid technology.
Chrysler announced in September 2008, that it was developing three electric vehicles and would sell the first of the models by 2010. In January 2009, at the Detroit Auto Show, Chrysler pledging to have 500,000 battery-powered vehicles on the road by 2013, including sports cars and trucks. By November 2009, Chrysler’s five-year strategy made no mention of electric cars. It was the only one of the six top-selling automakers without a hybrid offering.
In May 2012, Marchionne urged people not to buy Fiat 500 EVs because the company loses about USD 10 000 on every sale.
A 1957 Fiat 500 and a 2014 Fiat 500e
What actually concerns Marchionne is a fear that increased use of electric powertrains will lead to car manufacturers losing control to vehicle components suppliers. Yet, his head-burying approach will lead precisely to that outcome.
Case study # 2 – Volkswagen
Currently, Volkswagen uses MQB, Modularer Querbaukasten, translated as “Modular Transversal Toolkit” or “Modular Transverse Matrix”. It launched in 2012 for all VW Group brands, including Volkswagen, Seat, Audi and Škoda. It covers the A0 segment to the C segment. It is flexible in terms of powertrains and vehicle’s chassis. Larger vehicles use MLB, which stands for Modularer Längsbaukasten, translated as “Modular Longitudinal Matrix”. This was officially launched in 2012, but has its origins in 2007, with the Audi A5.
MQB and MLB are not platforms, but production systems for transverse and longitudinal engine vehicles, respectively, regardless of production platform, model, vehicle size or brand. There is a core “matrix” of components. A frequently cited example is their common engine-mounting core for all drivelines (e.g., gasoline, diesel, natural gas, hybrid and battery electric) of the specific approach (transverse or longitudinal). In each system, the pedal box, firewall, front wheel placement and windscreen angle are fixed. Otherwise vehicles can be shaped to fit any body style and size range. Results from this approach include reduced vehicle weights (which reduces vehicle operating costs) and allows different models to be manufactured at the same plant, reducing production costs.
The only problem with MQB and MLB is that they were eclipsed by Dieselgate, the Volkswagen emissions scandal, revealed in September 2015. The challenge is that while catalytic converter technology has been effective since the early 1980s at reducing nitrogen oxide in gasoline engine exhaust, it does not work well for diesel exhaust because of the relatively higher proportion of oxygen in the exhaust mix.
In 2005, there was disagreement at Volkswagen regarding the use of Mercedes-Benz BlueTec technology. If they had opted for this, there would have been no scandal. Instead, starting in the 2008, Volkswagen began using a common-rail fuel injection system that failed to combine good fuel economy with compliant NOx emissions. Already about 2006, Volkswagen programmed the Engine Control Unit to switch from good fuel economy and high NOx emissions to a low-emission compliant mode when it detected an emissions test. This made it into a defeat device.
Dieselgate forced Volkswagen to re-think its options. It lied and deceived consumers as well as environmental authorities. In order to claw back its reputation, Volkswagen decided to position itself as a leading battery electric vehicle manufacturer, but without a significant number of battery electric models to offer the public. In this new world, the driveline approach of MQB and MLB became obsolete.
Welcome Modularer Elektrifizierungsbaukasten (MEB). In terms of vehicle size this approximates that of the MQB, but is is restricted to electric vehicles. The MEB is optimizing axles, drive units, wheelbases and weight ratios for battery electric vehicles. It is focusing on the design and position of high-voltage drive batteries. battery. Its flat placement on the vehicle floor free up interior space. Other changes allow the dashboard to be more compact, the position of the centre console to vary, and provide space occupants in an autonomous vehicle to work or enjoy leisure.
Volkswagen has released a time frame for five EMB vehicles. The first will be the 125kW, 500km ID Hatchback shown at the Paris Motor Show in 2016. It could/should be available in 2019. Europe will be the priority market for this model. At the far end of the spectrum with a 2022 debut, is the ID Buzz. This has been a long journey for Volkswagen, which has been teasing the public with such a vehicle since 2001, when it presented a Microbus concept vehicle. The ID. Buzz was first shown at the North American International Motor Show, in Detroit, in 2017. It has potential markets throughout the world. The Buzz may also play a significant role in Volkswagen’s upcoming Uber rival, MOIA, launched in December 2016.
Volkswagen’s ID. vehicles based on MEB: Buzz, Hatchback, and Crozz (left to right)
MOIA was set up to redefine urban mobility. With offices in Berlin, Hamburg and Helsinki it aims to become a leading mobility service providers by 2025, including on-demand ridehailing and ridepooling services. It is investing in digital startups and collaborating with cities and established transport providers
Between these two vehicles, three other vehicles will be released. The next vehicle will be the ID Crozz crossover coupe. At 225 kW, it is more powerful, but will retain the same 500 km driving distance on a single charge. It will be available in Europe and China. The ID. Crozz was first shown at Shanghai Auto Show, in 2017. Perhaps the most important feature of the concept vehicle were the four roof-mounted laser scanners for autonomous driving mode, or in VW-speak, ID. Pilot mode.
After this come two additional vehicles with code names ID. Lounge and ID. AEROe. The Lounge could be a luxury car, possibly a promised Phaeton, whose second generation development was halted, then changed to an electric vehicle post Dieselgate. The AEROe could be a sporty four-door coupe.
In contrast to Fiat Chrysler, Volkswagen is focused on controlling its electric future.
