Ashok Leyland Takes Major Step Toward EV Leadership

Aditya Kondejkar Ashok Leyland’s move to develop and assemble its own battery packs marks one of its most strategically significant announcements in recent years. As India transitions toward a cleaner, multi-fuel commercial mobility ecosystem, this decision places the company at the center of the country’s electric commercial vehicle (ECV) transformation. The implications extend across technology, cost structure, competitive positioning, and long-term industry dominance.
At the core, battery packs account for 35–45% of an electric vehicle’s total cost, making them the single most influential factor in pricing and margins. By internalizing battery pack development, Ashok Leyland is aiming to break its dependence on third-party suppliers, reduce bill-of-materials cost, and secure tighter control over the EV value chain. This is crucial as global cell prices fluctuate and supply chains remain vulnerable to geopolitical shifts. In-house pack assembly gives the company cost stability, greater design flexibility, and freedom to optimize packs specifically for Indian duty cycles—ranging from stop-and-go urban e-buses to long-haul e-LCVs and future heavy-duty platforms.

Hybrids May Use 300% More Fuel Than Thought

Guy Youngs Study shows PHEVs exceed government estimates. There have been several studies that suggest that hybrid electric vehicles (also called PHEVs) are simply not the great environment saver that the marketing people are suggesting. A new study by the Fraunhofer Institute shows that on average, PHEVs use more than three times as much fuel as government estimates suggest.
The study is highly credible as it was based around on-board fuel consumption monitoring data from a massive 981,035 vehicles across Europe.
A gap of over 300% is severe and makes it hard for the EU to regulate something when the estimated numbers are so wildly different from reality. The EU is aware of this problem, and is taking some measures to fix it

PV-Powered Refrigerated Trailer Completes Test Run
Recently in Australia, Protrans Solutions conducted a successful trial with a battery-electric refrigerated trailer charged by onboard solar panels on the 1,100 miles Sydney-Brisbane round trip without using diesel to refrigerate the trailer unit. This demonstrates a depot-to-depot cold-chain capability.
But that’s easy, I hear you say, its Australia and its sunny. Well, how about cold and snowy Canada? Transport Canada’s Zero-Emission Trucking Program, recently published a study which monitored over than 200 thousand kms (124,224 miles) of diesel and electric truck data over a year of operations in the Montreal-area. There findings were staggering with nearly $200k of savings per electric truck

Researchers Compare Different EV Battery Types
Researchers from Newcastle University in the UK, and the Fire Service Academy in Poland, have undertaken a detailed comparison of three key battery technologies: conventional lithium-ion, emerging sodium-ion (SIB), and solid-state batteries (SSB)
They report that high energy lithium types (such as NMC battery variants) are more prone to fire risks (often referred to as thermal runaway) and these can become structural unstable when highly charged, leading to a potential fire risk. They also noted that thermal stability declines as nickel content increases. However, Lithium iron phosphate (LFP), is more robust and can thermal runaway even above 300 °C, making it less prone to fire risks. However, it offers lower voltage and energy density.

First Country To Ban Sale of Gas Cars Doing Fine
In 2024, Ethiopia made history by becoming the first country in the world to ban the sale and import of new internal combustion-powered vehicles. The decision was based on several factors, but, surprisingly, environmental reasons were quite low on the list.
The major reason for this seemingly bizarre action was economics. As a poor country with no oil reserves, Ethiopia was importing US$ 4 billion of refined fuel every year – US$ 4 billion may not seem like a big number, but to a country whose total budget is only US$ 14 billion, it’s massive.
The second major reason behind the decision was the completion of the Grand Ethiopian Renaissance Dam (GERD) which brings in massive amounts of energy to this energy poor country (it doubled the country’s generating capacity).

VW Tukan Is Brand’s First Flex Hybrid Vehicle
Volkswagen confirmed that the upcoming Tukan compact SUV will be its first flex fuel hybrid vehicle developed for Brazil. The model will combine a hybrid powertrain with a flex fuel ICE capable of running on gasoline and ethanol, aligned with local decarbonization strategies and Brazil’s biofuel infrastructure.
The vehicle is expected to be produced locally and positioned in the compact SUV segment, supporting Volkswagen’s regional electrification roadmap. The launch reinforces the company’s focus on hybridization technologies adapted to Brazilian market conditions and regulatory trends.

Ammonia-Fueled Marine Engine Approved
Swiss marine power company WinGD says it has completed both Type Approval Testing (TAT) and Factory Acceptance Testing (FAT) for its ammonia-fueled two-stroke marine engine, marking what it described as a world first.
The tests were completed in January 2026 on the X52DF-A-1.0 engine at the Engine & Machinery Division of HD Hyundai Heavy Industries (HHI-EMD) in South Korea, witnessed by Lloyd’s Register together with representatives from major classification societies and under the supervision of EXMAR.
The 52-bore engine is scheduled to be installed on a 46,000 m3 LPG/ammonia carrier ordered for EXMAR. According to WinGD, the vessel series is expected to become the first ammonia-fueled gas carriers to enter commercial service, representing an important step in the shipping industry’s decarbonization efforts. The company said the development program demonstrated strong safety, reliability and performance results under a fuel pathway widely viewed as one of the more promising zero-carbon options for long-distance marine transport.
WinGD said the X-DF-A engine uses high-pressure ammonia injection with a pilot fuel dose of around 5% at full load, while delivering load handling, dynamic response and fuel efficiency comparable to equivalent diesel-fueled X-Engines in both ammonia and diesel modes. The company also said emissions results were encouraging, including NOx levels during ammonia operation that were below those generated in diesel use, alongside negligible contribution of N2O to the overall greenhouse gas emissions footprint. WinGD added that it has already secured an early orderbook of around 30 X-DF-A engines across multiple vessel segments.Source: WinGD
Many alternative-fuel projects still sit at the concept or pilot stage. This one is different because it was executed on an engine destined for an actual commercial vessel program, under classification-society supervision and in cooperation with a yard ecosystem that can industrialize the result.

Tesla Committing Automotive Suicide

Guy Youngs Following its Q4 2025 financial update, Tesla appears to be pivotally shifting away from its identity as a traditional automaker. By phasing out the Model S and X to focus on ‘Transportation as a Service,’ leadership is betting heavily on an autonomous-first business model.
And instead of building on that success, expanding into new segments, addressing affordability, and competing with the flood of new EVs from legacy automakers and Chinese competitors, the company that revolutionized the auto industry is walking away from it.

Audit Court Calls Time on Hydrogen Inevitability
“The October 2025 special report from Germany’s Federal Audit Court, Implementation of the Federal Government’s Hydrogen Strategy, lands with unusual weight because it is not a policy critique or an academic intervention, but a statutory budgetary assessment delivered to Parliament,” reports Clean Technica.
It evaluates the hydrogen strategy against the legal requirements of the Energy Industry Act, namely security of supply, affordability, environmental sustainability, climate neutrality, and fiscal…
