As part of its Beyond100 strategy, Bentley will pursue sustainability in every area of its business as well as the products it makes and sells. The journey has already begun and a limited edition of the Flying Spur Hybrid provides a preview of what will come.

The Flying Spur Hybrid Odyssean Edition uses an advanced hybrid powertrain which can prove that hybridization will not compromise luxury or performance. The new powertrain combines a 2.9-litre V6 petrol engine with an advanced electric motor, generating a total of 544 ps/750 Nm (significantly more power than the Bentayga Hybrid). While able to cover the 0 to 100 km/h sprint in a claimed 4.3 seconds, the limousine is also said to have a range of over 700 kms when fully fuelled.

Sustainable materials throughout the cabin
New, even more sustainable materials are used throughout the cabin, directly reflecting design details showcased in Bentley’s centenary concept car. The cabin features panels of beautifully crafted tweed made from 100% British wool, twisting a blend of tonal colours into a bespoke yarn to create a unique natural luxury textile especially for Bentley.

The open-pore Koa veneer fascias and waistrails use 90% less lacquer than high-gloss veneers, and allow the natural surface texture and aesthetic of the wood to be enjoyed. Selected from only the very best, most figured stock available, open-pore veneer is painted with just three ultra-thin layers of lacquer, together totalling only 0.1 mm in thickness.

The centre console is finished in a sleek, minimalist Piano Linen veneer, while a dedicated tri-colour leather scheme lends the whole interior new depth. Together with new materials, sustainable leather is used widely across the cabin, thanks to its long-term durability. Indeed, Bentley’s own 1955 S1 Flying Spur was referenced during the design process, as the car still retains its original leather interior which, in spite of now being 66 years old, is still in immaculate condition.

Accents to the interior are in a soft, warm hide called Autumn, with customers able to choose from 5 specifications that utilize Beluga, Porpoise, Cricketball, Brunel or Burnt Oak leather in tandem with light, modern Linen hide. A unique Odyssean Edition treadplate becomes apparent when entering or exiting the car, and is matched with exterior D-pillar badging.

In common with the finishes seen in the EXP 100 GT interior, an exclusive new embroidery style sees thread colours blend calmly into one another across the width of each seat, defining and accentuating the ‘lofted diamond’ pattern unique to the Flying Spur – together creating a stunning effect employed here by Bentley for the first time.

On the exterior, painted Pale Brodgar accents on the 21-inch 10 twin-spoke wheels and lower brightware (front and rear bumpers, headlight and tail light surrounds and lower body side chrome) give a unique visual character. A curated exterior palette of six colours have been recommended to harmonise with the Pale Brodgar accents, but the full Bentley palette can be chosen from.

Real-world usage of Bentley Hybrids
As part of Bentley’s journey towards electrification and the Beyond100 strategy (delivering a product range composed entirely of plug-in hybrids or battery electric vehicles by 2026), a research activity has been undertaken to gain insights into customer usage of the Bentley Hybrid from owners.

Over 90% of owners use their first generation Bentayga Hybrid on a daily basis or several times a week and nearly 100% make use EV mode, which means running only on electrical power with zero emissions. Half of them consistently have journeys of less than 48 kms. In real-world terms, this means that the majority of the journeys, whether office commuting or school runs, can be achieved predominantly whilst producing zero emissions.

Right from the start, the battery pack has been a crucial element for the development of electric vehicles (EVs). The earliest EVs in the 1930s used very heavy batteries which made them unappealing, apart from the fact that performance was poor. Not much development of batteries took place in the decades that followed as the internal combustion engine dominated the auto industry and the battery’s role was minimal – mainly to start the engine.

It was only by the end of the 20th century that development of batteries started picking up, as interest in EVs started growing. Although the lead-acid type (the small one in the engine bay of cars) was used, it was totally unacceptable as its storage capacity was small and it was heavy. But R&D into this area accelerated and it was possible to use other chemical processes that could achieve a higher density and capacity for battery packs. Currently, it is the lithium-ion battery pack that is widely used in many EVs and hybrids.

Second generation of the Prius Aqua/Prius c

Now, Toyota has come out with another type of battery with a high output bipolar nickel-hydrogen battery. This is installed in the all-new Aqua (also known as Prius c) that is launched in Japan today and it is the first vehicle in the world to use this type of battery. Compared to the nickel-hydrogen battery that was used by the previous generation of the Aqua, the new more compact battery can provide approximately twice the output while enhancing performance and range.

Since the launch of the first-generation Prius in the late 1990s, Toyota has accumulated expertise both in the technological development and the quality management of batteries and hybrid systems. One subsidiary, Toyota Industries Corporation, has developed proficiency in analysis technologies for the development and performance assessment of materials through many years of developing batteries for electrified forklift trucks. By combining their respective fields of knowledge, the companies have worked to develop better batteries and their efforts have led to the development of bipolar nickel-hydrogen batteries.

First generation of the Prius c was sold in Malaysia for a few years when the government allowed full tax exemption on hybrid vehicles.

What is a bipolar battery?
In bipolar nickel-hydrogen batteries, a cathode is applied to one side of the current collector, and an anode to the other; several of these structures, which are known as ‘bipolar electrodes’, are stacked together to form  the battery architecture. Compared to non-bipolar nickel-hydrogen batteries, bipolar versions consist of fewer current collectors and other parts, enabling them to be made more compact. It is possible to stack a larger number of cells in bipolar nickel-hydrogen batteries than in non-bipolar nickel-hydrogen batteries of the same size.

In addition, since bipolar batteries have a greater active surface area and a simpler construction, there is lower resistance within the battery itself. This enables the flow of larger currents, leading to increased output. As an example, the bipolar nickel-hydrogen battery equipped to the all-new Aqua has an output approximately 2 times higher than the non-bipolar nickel-hydrogen battery used in the previous Aqua.

Toyota’s own battery factories
Toyota has its own battery manufacturing subsidiaries but it’s not known which company is producing these new batteries. Back in 1996, Toyota formed a joint-venture with Panasonic to develop and manufacture batteries for electrified vehicles. It was first known as the Panasonic EV Energy Company but changed its name to Primearth EV Energy Co., Ltd. (PEVE) in 2010 when Toyota became the majority shareholder.

PEVE focussed on making prismatic nickel–metal hydride (NiMH) as it worked on improving the quality of lithium-ion batteries. It began mass production of these higher performance batteries in early 2011.

Toyota also has a second joint-venture with Panasonic which was established just last year. Known as Prime Planet Energy & Solutions (PPES), it will handle development, manufacture, and sales of high-capacity and high-output prismatic lithium-ion batteries, solid-state batteries and next-generation batteries for automotive application.

Prime Planet Energy & Solutions is the second joint venture that Toyota has with Panasonic to make batteries for electric powertrains in motor vehicles. The company has two factories with the one in Japan (below) to have a capacity of 80,000 batteries annually and a second one in China which is expected to supply batteries for up to 400,000 hybrid electric vehicles per year.

PPES has an ambitious target to reduce battery costs by up to 50% this year. This will be achieved by expanding production capacity at two factories – one in Japan which will supply up to 80,000 battery electric vehicles annually, and a second one in China which is expected to supply batteries for up to 400,000 hybrid electric vehicles per year.
