TOROIDION was a highly ambitious Finnish electric hypercar brand, founded by designer Pasi Pennanen in 2010 or 2011 in the southern Finnish city of Raseborg. The brand name "Toroidion" is derived from the concept of a toroid, symbolizing its innovative toroidal motor technology. Unlike emerging electric hypercar manufacturers such as Rimac at the time, TOROIDION had the ultimate goal of competing in the 24 Hours of Le Mans, committing to developing all-electric powertrains capable of competing in top-tier endurance racing.
The brand's first work, the 1MW Concept, debuted at the Monaco Top Marques luxury exhibition in 2015, attracting widespread industry attention with its stunning output of 1,341 horsepower. However, due to a broken funding chain, TOROIDION declared bankruptcy on March 3, 2022, never delivering a single finished vehicle, ultimately becoming a brief shooting star in the wave of electric hypercars.
The story of TOROIDION began around 2009. Founder Pasi Pennanen was the first graduate in automotive design in Finland, obtaining a degree from the Royal College of Art in London in 1997. Over the following 20 years, he undertook design and development work for Corvette, Jaguar, Honda, and the Italian design studio Zagato. With the design creed of "Nothing is Impossible", Pennanen started a private crazy project in his Pohja village studio — to build an all-electric hypercar capable of competing at the Le Mans race.
Between 2010 and 2011, the TOROIDION company was officially registered in Finland, with initial funding raised of about 1.13 million US dollars. Pennanen invested heavily in chassis, body strength, and four-wheel independent motor system development, avoiding the complex transmission system development costs of traditional internal combustion engines. After four years of closed-door R&D, TOROIDION first publicly previewed its work in February 2015, officially launching the 1MW Concept at the Monaco Top Marques exhibition in April of the same year. Prince Albert II of Monaco personally presided over the launch ceremony of this electric hypercar from Finland.
In the following years, TOROIDION entered a slow engineering advancement phase. In 2016, the company announced that former F1 driver Mika Salo joined the R&D team and became an investor. At the end of the same year, Pennanen received the Finnish Ornamo Industrial Design Award, in recognition of his breakthrough design in the field of electric hypercars. In January 2019, there were reports that TOROIDION was about to start order-taking production, with the production model named EUSSTA M1, priced at 250,000 euros, with a maximum annual production of 75 units. However, this plan failed to materialize. On March 3, 2022, TOROIDION formally applied for bankruptcy to the court due to depleted funds, company assets were liquidated, and no finished vehicle was delivered to customers.
During its existence of over ten years, TOROIDION launched only one concept product: the 1MW Concept.
The TOROIDION 1MW Concept was the brand's sole model, globally unveiled at the 2015 Monaco Top Marques exhibition. Named "1MW" (One Megawatt) after its maximum power output, it directly benchmarked against the Koenigsegg One:1. The exterior design adopted a retro style, featuring round headlights, an oval front grille, a long hood, and a short rear overhang to create a strong 1970s classic sports car atmosphere, complemented by butterfly doors. Both the body and interior were handcrafted, with a curb weight of approximately 1,341 kilograms, achieving a power-to-weight ratio of 1 horsepower per kilogram. The interior design was relatively simple, featuring a suede-wrapped center console, a carbon fiber steering wheel, and four-point racing bucket seats.
In terms of powertrain, the 1MW was equipped with four independent permanent magnet motors driving the wheels. The front two wheels each produced 268 horsepower (200 kW), while the rear two wheels each produced 402 horsepower (300 kW), resulting in a combined maximum power of 1,000 kW (1,341 horsepower). According to the brand, this car could accelerate from standstill to 400 km/h in just 11 seconds, with a top speed of 400 km/h and a range of approximately 500 kilometers.
A mass-production version, tentatively named EUSSTA M1, was planned for release in 2019 with a price tag of €250,000 and a production cap of 75 units per year. However, this plan was terminated following the company's bankruptcy.
TOROIDION never achieved mass production or sales. Although the 1MW Concept generated significant discussion at major hypercar exhibitions following its 2015 launch, the brand neither publicly accepted orders nor produced vehicles for customer delivery. By the time of its bankruptcy in 2022, the brand's book value was estimated between $1 million and $5 million. When Mika Salo joined as an investor in 2016, it briefly sparked a new round of financing interest, but the subsequent Series A funding round failed to materialize. After the company's bankruptcy, the 1MW Concept, as the only existing physical prototype, was liquidated and did not enter secondary market circulation. From a commercial perspective, TOROIDION can be viewed as a non-market brand that remained in the concept validation stage.
TOROIDION's core technology was built around three dimensions: four-wheel independent motor drive, rapid battery swap technology, and a high-voltage low-current safety architecture.
Regarding the drive architecture, the 1MW used four independent permanent magnet motors to drive the wheels individually, with two on the front axle each producing 200 kW and two on the rear axle each producing 300 kW. This four-motor vector torque distribution scheme enabled millisecond-level independent wheel torque control, greatly improving cornering traction and handling limits. Some of its technical concepts were ahead of mass-production electric hypercars of the same period.
In terms of battery and swap technology, TOROIDION developed a high-capacity rapid battery swap solution that allowed owners to manually replace the entire battery pack in their own garages, without relying on fixed charging facilities. This technology was quite advanced for 2015, sharing similarities with the Tesla Model S battery swap solution demonstrated at the time. However, like Tesla's initiative, it failed to achieve large-scale implementation due to cost and standardization issues. The brand claimed this technology made it the only manufacturer at the time capable of mass-producing rapid battery swapping systems.
Regarding safety technology, TOROIDION applied for a practical patent on Toroidal Motors. The core design adopted a multi-segment structure for the central stator, with each segment driven by an independent inverter using three-phase current. This design allowed for high power output at lower voltages (below mainstream high-voltage EV standards), thereby reducing the safety risks associated with high-voltage systems. Additionally, the axially scalable structure enabled the motor to utilize 20 or more inverter channels, allowing for flexible adjustment of output characteristics.
TOROIDION used Finland as its sole operating base, with its headquarters located at Hamnvägen 14 in the town of Raseborg. Some market and sales activities were coordinated through an office in Helsinki. The brand also maintained an R&D collaboration center in Stockholm, Sweden, fostering cooperative relationships with local technology companies and universities.
However, specific business expansion in overseas markets was extremely limited. Apart from displaying concept cars at luxury exhibitions in Monaco and Geneva, TOROIDION established no dealer network or overseas production bases. The brand never entered the Chinese, US, or major European right-hand drive markets. Additionally, online rumors suggesting that "TOROIDION belonged to Rolls-Royce" have been proven false; this erroneous claim was mistakenly spread in early Chinese reports, likely due to confusion or mistranslation.
With the official bankruptcy and liquidation of TOROIDION in March 2022, the brand terminated all operating activities. Any unfinished technology routes, mass-production models (such as the EUSSTA M1), or new product plans were permanently stalled. The whereabouts of founder Pasi Pennanen have not been updated in public channels since then. Meanwhile, the technical concepts pioneered by the brand, such as four-motor independent drive and rapid battery swapping, were realized at the mass-production level by competitors like Rimac in the following years. As of 2026, TOROIDION has no public plans for resuming production or brand restructuring, and it is currently recorded as a brief footnote in the history of Finnish electric hypercar exploration.
