An Israeli company says a super-efficient engine it has created could drastically reduce fuel consumption and help power an auto industry revolution as manufacturers search for environmentally sound alternatives.
However, industry analysts question the reinvented internal combustion engine’s chances of success at a time when purely electric car technology is advancing and attracting investors.
The invention by Israel-based Aquarius Engines is being discussed by France’s Peugeot, the firm said.

Aquarius says the cost of the engine will be as low as US$100.
According to the firm, the engine can allow cars to travel more than 1,600km on a single tank of fuel, more than double current distances.
Such efficiency is vital as countries seek to reduce carbon dioxide emissions — a main cause of climate change.
SINGLE-ACTION ENGINE
Aquarius’ technology works by stripping back the traditional engine under the hood.
It replaces the combustion engine with its multiple pistons thrusting up and down with a single piston that goes side to side.
It has fewer than 20 parts and a single action, the company said.
In tests by the German engineering company FEV, the Aquarius engine’s efficiency was more than double that of traditional engines.
“It is the highest efficiency you will probably meet,” cofounder Gal Fridman told reporters at the company’s offices near the Israeli commercial capital of Tel Aviv. “It has the lowest emissions and the highest power-to-weight ratio.”
“We are discussing with them, as with many other start-ups, without obligation or a specific project,” a Peugeot spokesman said.
For Peugeot and others, the engine could help them compete with the growing popularity of electric cars, International Council on Clean Transportation senior fellow John German said.
He said the engine would work best as part of a plug-in hybrid system, with manufacturers looking at “the idea of putting a smaller, inexpensive, range extender” alongside a battery and motor.
However, he said Aquarius’ radical design and the changes it would require to manufacturing lines might make companies in a risk-averse industry hesitant.
The technology can also be used to make more efficient back-up generators and other products, the company says.
Aquarius is seeking its third round of funding and is aiming for US$40 million to US$50 million.
RISE OF ELECTRIC CARS
However, its challenge is to undermine the push toward electric-only cars, the Economist Intelligence Unit’s Ana Nicholls said.
She said recent evidence suggested that “people are starting to trend away from hybrid cars towards fully electric vehicles.”
US-based electric car maker Tesla has announced that it is on course to sell about 50,000 vehicles in the second half of this year.
Nicholls said that automotive giants, with research and development budgets stretched thin, could be wary of investing in Aquarius.
“I think the feeling in the industry at the moment is very much that if they are going to put their resources behind something then probably fully electric engines are the way to go,” she said.
Fridman said there is too much “hype” around purely electric cars, and that their actual popularity is limited because of small ranges and high prices.
“Fifty thousand units is nothing,” he said of Tesla’s projected sales. “It is amazing as there has been a push from governments, municipalities, etc. And still after 15 years, the segment is not really successful.”
Aquarius is entering the competition late and playing “catch up,” said Franco Gonzalez, senior technology analyst at the IDTechEx analysis firm.
“Automotive companies take seven to 10 years to implement a new technology,” he said. “So, Peugeot would need to accelerate their implementation very, very fast to at least catch up to what Tesla, BYD, Nissan and other companies supporting the electric car model are achieving.”
German said it was too early to say if the engine could make a major dent.
“A lot depends on the path the electric vehicle revolution takes. If pure battery electrics sell well then there probably isn’t much need for this kind of engine,” he said. “But if people balk at the long recharge time and high costs of battery-only cars, then systems like these might be the future.”
BYPASSING CHINA TARIFFS: In the first five months of this year, Foxconn sent US$4.4bn of iPhones to the US from India, compared with US$3.7bn in the whole of last year Nearly all the iPhones exported by Foxconn Technology Group (富士康科技集團) from India went to the US between March and last month, customs data showed, far above last year’s average of 50 percent and a clear sign of Apple Inc’s efforts to bypass high US tariffs imposed on China. The numbers, being reported by Reuters for the first time, show that Apple has realigned its India exports to almost exclusively serve the US market, when previously the devices were more widely distributed to nations including the Netherlands and the Czech Republic. During March to last month, Foxconn, known as Hon Hai Precision Industry
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) and the University of Tokyo (UTokyo) yesterday announced the launch of the TSMC-UTokyo Lab to promote advanced semiconductor research, education and talent development. The lab is TSMC’s first laboratory collaboration with a university outside Taiwan, the company said in a statement. The lab would leverage “the extensive knowledge, experience, and creativity” of both institutions, the company said. It is located in the Asano Section of UTokyo’s Hongo, Tokyo, campus and would be managed by UTokyo faculty, guided by directors from UTokyo and TSMC, the company said. TSMC began working with UTokyo in 2019, resulting in 21 research projects,
Ashton Hall’s morning routine involves dunking his head in iced Saratoga Spring Water. For the company that sells the bottled water — Hall’s brand of choice for drinking, brushing his teeth and submerging himself — that is fantastic news. “We’re so thankful to this incredible fitness influencer called Ashton Hall,” Saratoga owner Primo Brands Corp’s CEO Robbert Rietbroek said on an earnings call after Hall’s morning routine video went viral. “He really helped put our brand on the map.” Primo Brands, which was not affiliated with Hall when he made his video, is among the increasing number of companies benefiting from influencer
Quanta Computer Inc (廣達) chairman Barry Lam (林百里) yesterday expressed a downbeat view about the prospects of humanoid robots, given high manufacturing costs and a lack of target customers. Despite rising demand and high expectations for humanoid robots, high research-and-development costs and uncertain profitability remain major concerns, Lam told reporters following the company’s annual shareholders’ meeting in Taoyuan. “Since it seems a bit unworthy to use such high-cost robots to do household chores, I believe robots designed for specific purposes would be more valuable and present a better business opportunity,” Lam said Instead of investing in humanoid robots, Quanta has opted to invest
