First look at the hydrogen fuel cell powertrain being developed by BMW and Toyota

Besides collaborating on the BMWZ4 and Toyota Supra, the BMW Group and Toyota have been working together on fuel cell technology. As Toyota has already commercialised a fuel cell vehicle (the Mirai), it can offer a good deal of knowledge and information to developing the alternative powertrain technology.

“We are convinced that various alternative powertrain systems will exist alongside one another in future, as there is no single solution that addresses the full spectrum of customers’ mobility requirements worldwide. The hydrogen fuel cell technology could quite feasibly become the fourth pillar of our powertrain portfolio in the long term. The upper-end models in our extremely popular X family would make particularly suitable candidates here,” said Klaus Frohlich, Member of the Board of Management of BMW AG, Research and Development.

The BMW Group has been working with Toyota on fuel cell technology since 2013. Now it can offer the first virtual insights into the powertrain system for the BMW i Hydrogen NEXT.

Future prospects
Although the BMW Group has no doubt as to the long-term potential of fuel cell powertrain systems, it will be some time before the company offers its customers a production car powered by hydrogen fuel cell technology. This is primarily due to the fact that the right framework conditions are not yet in place.

“In our view, hydrogen as energy carrier must first be produced in sufficient quantities at a competitive price using green electricity. Hydrogen will then be used primarily in applications that cannot be directly electrified, such as long-distance heavy-duty transport,” said Frohlich.

The requisite infrastructure, such as an extensive Europe-wide network of hydrogen filling stations, is also lacking at present. However, the BMW Group is pressing ahead with its development work in the field of hydrogen fuel cell technology. The company is using the time until the infrastructure and sustainably produced hydrogen supply are in place to substantially reduce the cost of manufacturing the powertrain system.

Initial technical details
The fuel cell system for the powertrain for the BMW i Hydrogen NEXT generates up to 125 kW (170 bhp) of electric energy from the chemical reaction between hydrogen and oxygen from the ambient air. The vehicle emits nothing but water vapour. The electric converter located underneath the fuel cell adapts the voltage level to that of both the electric powertrain and the peak power battery, which is fed by brake energy as well as the energy from the fuel cell.

The vehicle also accommodates a pair of tanks that can together hold 6 kgs of hydrogen. Refuelling only takes 3 to 4 minutes and the capacity of the tanks gives a long range of travel.

The fifth-generation eDrive unit set to make its debut in the BMW iX3 is also fully integrated into the BMW i Hydrogen NEXT. This hydrogen fuel cell electric powertrain will go through a pilot run in a small batch of SUVs based on the current BMW X5 that the BMW Group plans to present in 2022. However, volume production with hydrogen fuel cell technology will only start in the second half of this decade, at the earliest. That too will depend on the global market conditions and requirements.

Collaboration with Toyota
Besides partnering with the Japanese carmaker on the development and industrialisation of fuel cell technology for the mass market, the two companies are also founding members of the Hydrogen Council. A wealth of other leading companies in the energy, transport and industrial sectors have joined the Hydrogen Council since 2017, swelling its ranks to over 80 members. The BMW Group’s participation in the research project BRYSON (a German acronym for ‘space-efficient hydrogen storage tanks with optimised usability’) underlines its faith in the future viability and potential of hydrogen fuel cell technology.

Genesis GV80 Concept SUV unveiled at New York

Genesis, Hyundai’s luxury sub-brand has unveiled a new SUV Fuel Cell concept vehicle at the New York International Motorshow. Meant to be a futuristic SUV powered by hydrogen, the vehicle, called the GV80 Concept SUV, features a design that conforms to the current design language used by the contemporary crop of Genesis vehicles.

It incorporates the signature Genesis crest grille that stretches to over most of the front fascia. The vehicle has quad headlamps that encase jewel-like graphics, which lends a certain luxury appeal to its appearance. The futuristic rear tail lights feature laser fiber optic technology that is said to offer a unique Genesis lighting effect. The lower rear fascia is designed to channel air efficiently out of the vehicle to help cool the the fuel cell vehicle’s powertrain. Areas around the front wheels and side rocker panels feature cut-outs that help channel air cleanly through to aid better aero flow.

Hyundai has fitted 23-inch mesh alloy wheels which are designed to reduce weight and cool the large brake system. Electronic door handles sit flush inside the body work that help airflow and provide the car with a cleaner and more elegant look. The side pillars are constructed with structural trusses which provide the cabin with an airy feel.

Inside the GV80 features modern futuristic design thanks to a multi-function interactive controller with capacitive touch. Dominating the centre console is the 22-inch curved OLED infinity display which provides different information to the front driver and passenger. The top of the interactive multi-function controller features a concave gorilla glass touchpad and knurled metal wheel with handwriting recognition. Through the use of the touch control system, each if its metal strings allows direct access to the most commonly used functions including Navigation, Entertainment, Communication, and Environment.

The GV80 features a spacious cabin which is complemented by the ash wood centre console and floor boards. The GV80 features exquisite semi-aniline leather interior, with quilted diamond stitching on the interior door panels, seat inserts and center console side. The use of suede, dark gray leather and slate ash wood provide the vehicle with a luxury business appeal.

No word yet on whether the GV80 will actually make it on the showroom floor, but the vehicle that it eventually turns out to be will feature the Korean automaker’s latest Fuel Cell technology that will definitely appeal to the alternative fuel community. Unfortunately, there are very few places that have sufficient infrastructure to support hydrogen fuel cell technology for now. Unless more countries embrace the technology, it will take a long time for hydrogen power to make its mark in the automotive industry.

Hyundai unveils Fuel Cell Concept at Seoul Motorshow

At the ongoing Seoul International Motorshow, Hyundai has also unveiled its stab at the hydrogen powered vehicle of tomorrow. Dubbed the Future Eco (FE) Fuel Cell Concept, the car is meant to provide a glimpse at the actual production ready vehicle, which will be launched in February next year.

This unveiling hints at the possibility of realizing the Korean automakers’s hopes of becoming a global leader of manufacturing mass-produced hydrogen vehicles of tomorrow. The new car, when launched, will feature advanced driver assistance technologies and a respectable 800km range on a tank of hydrogen.

Apart from that, the car will also have clever tech to aid occupant comfort, convenience and safety. One such feature is the ability of this vehicle to take the byproduct of its fuel cell process, which is water, and use it for its air humidifier in the cabin. The added moisture should provide occupants with better levels of comfort especially on long journeys.

But that wasn’t the only tech on display, besides the Smart House concept that blurs the line between the mobility of a car and practicality offered by a house, Hyundai’s VR take on the futuristic Ioniq was also intriguing. The automaker had Virtual Reality simulators at their stand which allowed visitors to peer into the abilities of an autonomous Ioniq. The simulator demonstrates how the actual car can behave with advanced auto-piloting capabilities through the use of its many sensors and radar systems.

Hyundai says that the autonomous Ioniq is one of few such vehicles to have its self-driving systems integrated into the front bumper instead of the big bulky ones placed on the roof of some mainstream automakers’ prototypes. The company will be able to accomplish this by integrating the new systems with existing ones which include Smart Cruise Control’s forward facing radar and Lane Keeping Assist cameras.

Expect more from the Korean giant in the future but until then, its most cherished vehicle here in Malaysia is the hybrid Ioniq which blends both electric and petrol power to offer better efficiency and emissions.
