OXFORD (Reuters) – Speed has always been paramount for supercar makers, and now they\u2019re in the race of their lives to go electric before climate policy cuts their combustion engines.<\/p>

That\u2019s why the likes of Ferrari and Mercedes-Benz are turning to startups such as Oxford-based electric motor company YASA for expertise and technology to solve the unique challenges of electrifying the highest-performance vehicles.<\/p>\n

Batteries are immensely heavy and electric motors overheat if driven too hard – big problems for a niche industry that charges hundreds of thousands of dollars for lightweight cars capable of screaming round 10 laps of a track at full throttle.<\/p>\n

This year Daimler bought YASA, which has developed an \u201caxial flux\u201d high-performance electric motor that weighs 23 kg (50.7 lb), a fraction of a near-300 kg V12 engine in a Ferrari, and is about the size and shape of a steering wheel.<\/p>\n

YASA already makes motors for Ferrari, Swedish supercar maker Koenigsegg, plus an unnamed British supercar company. It will now supply the high-performance AMG brand at Daimler, which will soon assume the name of its car business Mercedes-Benz.<\/p>\n

Based just a few miles from YASA, Saietta has developed a range of water-cooled axial flux motors. The company is gearing up to produce motors for the vast Asian motorbike market, but told Reuters it had created a larger prototype and was in talks with one hypercar maker, and that two others had expressed interest.<\/p>\n

\u201cThese manufacturers know combustion engines forwards, backwards and inside out,\u201d said Saietta Chief Commercial Officer Graham Lenden. \u201cBut they don\u2019t know electric powertrains and what they\u2019re looking for is someone to hold their hand.\u201d<\/p>\n

Yet this is uncharted territory, with no clear road map to electric for high-performance vehicles yet. Supercar makers will have to invest billions of dollars to survive the disappearance of combustion engines, with no guarantee that the technologies they adopt will pay off in the long term.<\/p>\n

WEIGHT IS THE ENEMY<\/h2>\n

Supercars and the highest-end hypercars – both sportscars that verge on professional racing level performance – are a highly profitable, capital intensive niche market for automakers.<\/p>\n

Consultancy AlixPartners and data firm IHS Markit estimate more than 152,000 \u201cluxury\u201d and \u201csuper luxury\u201d sportscars ranging in price from 100,000 to 10 million pounds ($137,000-13.7 million) will be sold globally in 2021, with the market expected to rise nearly 50% to 223,000 cars in 2026.<\/p>\n

YASA founder Woolmer said, though, that his company\u2019s long-term brief from Daimler was to bring the costs down in future iterations of its motor so the German carmaker can use them across its entire car range as it shifts to electric.<\/p>\n

\u201cAutomotive technology doesn\u2019t scale to volume overnight, you tend to start with the premium niche sectors,\u201d Woolmer says.<\/p>

Makers of high-performance electric cars will ultimately have to find ways to develop lighter, more powerful batteries. But as today\u2019s battery technology cannot compete with the sustained power of a petrol engine, they are also rethinking everything from electric motors to car body materials.<\/p>\n

Axial flux electric motors are flat, round devices – dubbed \u201cpancakes\u201d – that are lighter and more efficient than conventional cylindrical \u201cradial flux\u201d motors, or \u201csausages.\u201d<\/p>\n

YASA\u2019s motor is oil cooled, so will never overheat and is far more efficient than a conventional motor, said Tim Woolmer, who developed the device as part of his doctorate at the University of Oxford and then founded the company in 2009.<\/p>\n

Because the motor is more efficient, it can extend the range of an electric vehicle up to 7%, or because it uses less power it allows carmakers to take out some of the heavy batteries and reduce their vehicle\u2019s weight by to 10%, he added.<\/p>\n

YASA has a small facility at its Oxford headquarters where it makes motors for Ferrari\u2019s SF90 Stradale hybrid and 296 GTB hybrid models, and test motors for AMG. Daimler is studying how to scale up that production at its own factories.<\/p>\n

YASA\u2019s CEO Chris Harris said its acquisition by the German giant had not ended its work with clients like Ferrari.<\/p>\n

\u201cThey want us to continue working with our supercar customers because that\u2019s the leading edge,\u201d he added. \u201cThat technology when it matures cascades down.\u201d<\/p>\n

Ferrari\u2019s Chief Technology Officer Michael Leiters described the YASA motor in its hybrid models as an \u201cautomotive first\u201d, adding that the Italian sportscar maker would lean on the technical expertise of suppliers in its quest to go electric.<\/p>\n

WANTED: BATTERY REVOLUTION<\/h2>\n

Car companies are also looking beyond motors in their weight-loss plans.<\/p>\n

Mate Rimac, CEO of Croatian electric hypercar maker Rimac, said the chassis and the body of its C-Two model were both made of carbon fibre, and that batteries formed part of the car\u2019s structure to save weight.<\/p>\n

The company, which is forming here a joint venture with Volkswagen’s luxury sportscar unit Porsche that will include VW’s Bugatti brand, also uses “torque vectoring” to boost performance – motors in the wheels to help take corners.<\/p>\n

British sportscar maker Lotus has developed a new electric platform using light aluminium alloys that cuts the vehicle\u2019s structural weight 37% and will start producing its first fully-electric sports car in 2026.<\/p>\n

Owned by China\u2019s Geely and Malaysia\u2019s Etika Automotive, Lotus also operates as an auto supplier and engineer to other carmakers. The company is in advanced talks to supply the platform to another carmaker and has received expressions of interest from several others, managing director Matt Windle said.<\/p>\n

\u201cWith the cost and speed of electrification, collaboration is the way to go,\u201d Windle said.<\/p>\n

Chinese automaker FAW has teamed up with U.S.-based engineering and design firm Silk EV to form the Silk-FAW venture, which plans to build electric sportscars in Italy.<\/p>\n

It is using carbon-fibre components for the vehicle chassis and looking to a high-revolution motor using copper-wiring technology from the aerospace sector to cut the motor\u2019s weight by 20%, though it is also exploring other options.<\/p>\n

\u201cWeight saving is even more important than a higher level of power,\u201d said Roberto Fedeli, Silk-FAW vice president for innovation and technology.<\/p>\n

Cutting weight and using more efficient motors may be enough for most wealthy sportscar buyers who use their vehicles for recreation or to commute, and are unlikely to want to execute multiple high-speed laps around a race track.<\/p>\n

Those who do could be in for a long wait.<\/p>\n

\u201cUnless batteries go through a massive revolution, you\u2019re never going to carry the amount of energy that a fuel tank will carry,\u201d said YASA founder Woolmer.<\/p>\n

\u201cFor longer-form racing, it\u2019s going to be a while.\u201d<\/p>\n
