2027 Kawasaki Versys: Even sportier, featuring a 948cc, 122 hp engine

Kawasaki is expanding its family of sport-touring motorcycles with one of the most significant additions to its lineup. The new Kawasaki Versys 900 elevates the Versys concept to a sportier level, incorporating a 948cc inline-four engine derived from the Z family. According to the brand, it is the sportiest Versys ever created.

New chassis and a sportier approach...For this Versys 900, Kawasaki has developed a new tubular steel frame, aimed at balancing rigidity with front-end feel. The rear subframe is designed to support travel with a passenger and luggage, while a near 50:50 weight distribution ensures more agile handling.

The chassis is complemented by long-travel suspension and 17-inch sport-oriented wheels, fitted with Metzeler ROADTEC 01 tires. An upright riding position, a seven-position adjustable windshield, and a seat height that can be adjusted between 825 and 845 mm reinforce its focus on touring without sacrificing control.

The first Versys with ARAS assistance...One of the most notable updates lies in its technology. The new Versys 900 is the first in the Versys line to be equipped with ARAS—Kawasaki’s suite of advanced rider assistance systems.

Recycled plastic asphalt may boost pavement performance, limit particle release

Asphalt containing recycled plastic held together better than conventional asphalt and showed a lower level of plastic-like particles after combined traffic and moisture-related laboratory testing, according to a study led by Penn State researchers. The findings suggest that improved pavement durability may help limit particle release, the team said, but field studies are needed to determine whether the same pattern occurs on real roads.

The study, published in the Journal of Cleaner Production, examined recycled plastic-modified asphalt made with low-density polyethylene, or LDPE. While recycled plastics are increasingly being explored to divert waste from landfills and improve pavement performance, the researchers said less is known about whether plastic-containing pavement could release microplastics as roads age, experience traffic and endure weather.

“Our goal was to understand whether asphalt pavement containing recycled plastic could release microplastic particles as it is damaged over time,” said Shihui Shen, distinguished professor of rail transportation engineering at Penn State Altoona and corresponding author on the paper. “That environmental question has received much less attention than the engineering performance of the pavement.”

Microplastics are particles smaller than 5 millimeters — the width of a pencil eraser — and have been found in water, soil and air. Pavements can contribute particles to the environment through tire wear, pavement deterioration and plastic-containing construction materials. Particles released from road surfaces could potentially be carried into roadside soil and stormwater by wind and rainfall.

To investigate that possibility, the researchers compared conventional asphalt with asphalt containing recycled LDPE. They prepared the plastic-containing asphalt by mixing shredded plastic with crushed stone and reclaimed asphalt pavement, then adding the binder that holds the mixture together.

The researchers then exposed samples to two established laboratory pavement tests designed to simulate stresses caused by traffic and weather. In the Hamburg Wheel Tracking Test, steel wheels repeatedly rolled over asphalt specimens submerged in hot water, simulating the combined effects of traffic loading, heat and moisture. In a second test, called the Moisture-Induced Stress Tester, samples were subjected to elevated heat, moisture and repeated hydrostatic water pressure.

“Together, these tests reproduce important aspects of roadway damage under controlled laboratory conditions,” said Zhen Liu, a research assistant professor at the Chinese University of Hong Kong who completed a postdoctoral fellowship at Penn State’s Larson Transportation Institute within the Department of Civil and Environmental Engineering and the study’s lead author. “We then collected the released particles and analyzed them for possible plastic content.”

Working with Penn State’s Environmental Contaminants Analytical Laboratory, the researchers analyzed the chemical signatures of the asphalt’s ingredients to create a reference library. They then used infrared imaging to measure individual particles and compare their chemical signatures with those reference materials. This helped the team identify particles resembling LDPE. To compare samples, the team measured the combined area of detected LDPE-like particles relative to the weight of the asphalt tested.

“Pavement debris is not a simple environmental sample,” said Odette Mina, director of laboratories for Penn State’s Institute of Energy and the Environment and a co-author on the paper. “The combination of bulk-material characterization and particle-level infrared imaging allows us to connect the original pavement material with the identity, abundance and physical characteristics of particles released during simulated service conditions.”

Asphalt containing recycled plastic generally held together better than conventional asphalt during laboratory testing. After combined traffic and moisture-related stresses, it also showed a lower measured level of particles with chemical signatures resembling LDPE. Together, those findings suggest that improving pavement durability may help limit particle release, according to the team.

“Asphalt binder and LDPE share some infrared features, which can complicate both identifying particles as plastic and determining their source,” Shen said. “The findings do not rule out the possibility that either plastic-modified or unmodified asphalt mixtures can release microplastics.”

The study tested one asphalt formulation and one source and amount of recycled plastic, so the researchers cautioned that findings cannot yet be generalized to other pavement materials or real-road conditions.

The study also highlighted the importance of contamination control in microplastics research, Mina explained. The team cleaned testing equipment and internal piping, ran background tests without asphalt specimens, used glass containers and apparatus where possible, used pre-filtered water and covered samples during preparation. The imaging system also generated match-quality scores to help researchers evaluate confidence in particle identification.

Those steps are important because microplastics can be introduced inadvertently through laboratory equipment, air, water or previous samples, potentially causing background particles to be mistaken for particles released by asphalt, Mina said.

The researchers said field studies are needed to determine whether their laboratory findings hold on real roads over longer periods. Future field studies will need to account for traffic volume, rainfall, temperature changes, sunlight, pavement aging, runoff chemistry and differences in recycled-plastic and asphalt formulations.

“Field studies, reliable sampling and long-term monitoring will give transportation agencies stronger evidence for weighing pavement-performance benefits against potential environmental impacts,” Shen said. “Ultimately, more reliable environmental data can help agencies make more informed decisions about recycled-plastic pavement technologies.”

In addition to Liu, Shen and Mina, the research team included Hlengilizwe Nyoni, assistant research professor of the Institute of Energy and the Environment, and was supported by the following industry partners: Eco Plastic Products of Delaware, New Enterprise Stone and Lime Co., Inc. and HRI, Inc.

The research was supported by the U.S. Department of Transportation Region 3 Center for Integrated Asset Management for Multimodal Transportation Infrastructure Systems and the Penn State Commonwealth Campuses Research Collaboration Development Program. The content is solely the responsibility of the authors and does not necessarily represent the official views of the funders.

Adding recycled plastic to asphalt can increase pavement durability, reduce maintenance costs, and mitigate the release of microparticles into the environment under controlled laboratory conditions.

Recent studies led by institutions such as Penn State University and the University of Texas at Arlington (UTA) demonstrate that polymers derived from consumer waste (such as plastic bottles, bags, and even discarded fishing nets) act as effective modifiers for asphalt binders in hot-mix asphalt.

Key benefits identified:

• Rutting Resistance: Plastic increases the binder's stiffness and viscosity, making roads far more resistant to the weight of heavy vehicles and extreme heat.

• Cost Reduction: Research estimates that an optimal content of 8% recycled plastic by asphalt weight can generate savings of approximately US$ 38.83 per ton of material (or about US$ 388.30 per kilometer constructed).

• Microplastic Retention: Field tests in pioneering locations like Hawaii found that, after months of use, road wear did not spread microplastics into the ecosystem, as the plastic remained chemically fused and encapsulated within the binder matrix.

Despite excellent laboratory results, the transition to commercial roadways still faces significant technical hurdles:

*Thermal Flexibility | Increased stiffness improves performance in heat but can reduce flexibility at extremely low temperatures, raising the risk of cold-weather cracking.

*Scale Incompatibility | Laboratory ovens allow sufficient time for plastic to melt evenly, whereas industrial asphalt plant processes are too rapid to ensure the same homogeneity.

*Air Pollution | Certain plastics, such as PVC (polyvinyl chloride), release harmful toxic gases (like chlorine and chlorinated compounds) when subjected to high temperatures during the mixing process.

New platform tackles critical material risks in electric motors

Electric motors sit at the heart of modern industrial civilization. They propel hybrid and electric vehicles down highways, drive the pumps and compressors of manufacturing plants, spin the fans and compressors inside household appliances, and underpin the energy infrastructure that keeps grids stable. Yet the technologies that make these machines possible depend on a narrow set of critical materials, most notably copper for windings and conductors and rare earth elements for the permanent magnets that give many motor designs their exceptional power density. As demand for electrification accelerates worldwide, the supply chains that deliver these materials have come under intensifying pressure from geopolitical tension, trade restrictions, price volatility and concentrated production in a handful of countries. For manufacturers, the question of which motor technology to invest in has never been more consequential, or more difficult to answer with confidence.

Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed a response to this dilemma. The platform, called Motor Decide, is described by its creators as a Super Intelligence, or SI, driven decision-support tool that helps manufacturers evaluate competing electric motor technologies before market conditions shift against them. Rather than telling a company which motor to build, the system models how different motor options would perform across a range of future scenarios, weighing performance characteristics against critical material availability, supply chain stability, technology maturity and long-term resilience to changing market conditions. The goal is to move technology selection away from instinct and toward structured, data-driven analysis.

“Many companies make technology decisions based largely on market momentum or competitor activity,” said ORNL’s Praveen Kumar, lead researcher on the project. “We wanted to create a tool that helps organizations make more informed, data-driven decisions for the long term.” The distinction matters because motor technology choices lock in material demand for years or decades. A manufacturer that commits to a permanent magnet motor design today is implicitly committing to a continued supply of rare earth elements, and if those supplies tighten or prices spike, the entire product line can become economically vulnerable. Motor Decide is designed to surface those hidden dependencies before the commitment is made.

The platform does not design motors directly. Instead, it analyzes which motor technology may be the best fit for a specific application under changing market and supply chain conditions. A manufacturer, for example, could use the tool to compare several motor technologies for an electric system and determine which option would remain the most reliable and cost-effective path to production if material prices spiked or supplies became strained. This scenario-based framing is what separates the tool from conventional comparison exercises, which typically evaluate motors under a single set of assumptions about cost and availability that may be obsolete by the time a product reaches the market.

Under the hood, Motor Decide combines SI-driven analysis, advanced modeling and large-scale scenario analysis to evaluate how motor technologies could perform under fluctuating material costs and supply chain disruptions. Researchers can model what happens if copper prices increase sharply, or if a newer motor technology becomes commercially viable years from now. The output is a ranked set of motor technology options accompanied by insights into cost, performance, critical material use, manufacturability and long-term risk. By quantifying these dimensions together, the platform gives decision-makers a structured view of tradeoffs that would otherwise be scattered across procurement data, engineering assessments and market forecasts.

As manufacturers face growing uncertainty tied to critical material shortages and global supply chain disruptions, the Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL) researchers have developed a Super Intelligence (SI)-driven platform to help companies evaluate electric motor technologies before market conditions shift.

Called Motor Decide, the platform evaluates motor technologies using factors such as performance, critical material availability, supply chain stability, technology maturity and long-term resilience.

Critical materials such as copper and rare earth magnets are essential components in the electric motors that power transportation, manufacturing systems and energy infrastructure. As industries work to reduce dependence on vulnerable supply chains and manage rising geopolitical and market uncertainty, selecting the right motor technology has become increasingly complex.

“Many companies make technology decisions based largely on market momentum or competitor activity,” said ORNL’s Praveen Kumar, lead researcher on the project. “We wanted to create a tool that helps organizations make more informed, data-driven decisions for the long term.”

SI modeling prepares manufacturers for supply chain uncertainty...Electric motors power a wide range or technologies, from hybrid or electric vehicles, to industrial systems and household appliances. Many depend on critical minerals such as copper and rare earth elements that face growing supply chain pressures. Motor Decide was created to help companies consider possible alternatives.

Rather than designing a motor directly, Motor Decide analyzes which motor technology may be the best fit for a specific application under changing market and supply chain conditions. A manufacturer, for example, could use the tool to compare several motor technologies for an electric system and determine which option would remain the most reliable and cost-effective path to production if material prices spike or supplies become strained.

The system combines SI, advanced modeling and large-scale scenario analysis to evaluate how motor technologies could perform under fluctuating material costs and supply chain disruptions. Researchers can model what happens if copper prices increase sharply or if a newer technology becomes commercially viable years from now. The result is a ranked set of motor technology options with insights into cost, performance, critical material use, manufacturability and long-term risk.

“We define the operating environment in which the decision is being made,” Kumar said. “That includes procurement sources, manufacturing readiness, technology maturity and application requirements. Then we test how those factors change under different scenarios.”

The platform also accounts for how organizations make decisions, helping users evaluate tradeoffs and quantify risk when comparing emerging technologies. “People ultimately own the decision,” Kumar said. “We are trying to quantify uncertainty and incorporate it into the decision-making process.”

NTRC expertise supports next-generation motor innovation...The project builds on decades of motor, power electronics and transportation research conducted at the National Transportation Research Center, DOE’s only user facility dedicated to transportation research and a hub for advanced mobility innovation. At NTRC, ORNL researchers work with industry partners to advance next-generation mobility and manufacturing technologies.  

“We are combining motor research expertise with SI-driven analysis in a way that can help industry make smarter, more resilient technology decisions,” said Kumar. Researchers envision the tool helping manufacturers reduce dependence on vulnerable supply chains while planning future products more strategically.

From SI-guided technology selection to motor design...Motor Decide is also designed to work alongside another ORNL-developed platform, Motor AI, which uses SI-assisted engineering tools to accelerate detailed motor design. While Motor Decide helps identify the best motor technology pathway, Motor AI performs the detailed motor design work needed to bring those concepts to life.

Once a company selects a preferred motor approach, researchers can transition the results into Motor AI to generate detailed design configurations and engineering specifications. Together, the tools could help accelerate the development of more resilient electric motor systems while reducing the risks associated with critical material shortages, volatile supply chains and rapidly changing global markets.

The effort reflects ORNL’s broader mission to combine super intelligence, advanced manufacturing and energy research to help strengthen U.S. competitiveness and industrial resilience. Researchers are continuing to evaluate and expand the platform’s capabilities for future applications.

When your car is making weird noises, the best thing you can do is listen carefully, identify where the sound is coming from, and get it checked by a professional mechanic before it becomes a bigger problem. Below, we cover the most common car noises when driving, what they mean, and why you should never ignore them.

A car often starts signaling a fault long before a warning light appears on the dashboard. Unusual engine noises, creaking when turning, knocking sounds when driving over bumps, or a humming noise that grows louder while driving can be the first signs that something is wrong. That is why it is important to pay attention to changes; a timely reaction can prevent a serious breakdown and an expensive repair.

The challenge is that the same sound could stem from a completely harmless cause or indicate a fault requiring repairs costing thousands of euros. Therefore, unusual noises should not be ignored, especially if they appear suddenly or become increasingly pronounced, reports Autonews.

Squealing or chirping noises...If you are wondering, “Why is my car making squeaking noises?”, it could be one of several issues. The most common cause is worn or loose drive belts, which control the alternator, power steering, and air conditioning. When these belts wear down, they can slip on the pulleys, creating a sharp squealing noise, especially when you start the engine or accelerate.

You might also hear squeaking noises from your brakes. Car noises when braking often indicate worn brake pads or warped rotors. This is not something to delay, as worn brakes can affect stopping distance and safety.

If you hear squealing from under the bonnet or while driving, book a mechanical inspection immediately. Replacing belts and brake pads early prevents much more expensive damage later.

Grinding or rattling sounds...A grinding noise can send a shiver down any driver’s spine, and for good reason. Grinding car noises often signal serious mechanical wear. If you hear grinding when you brake, it usually means the brake pads are completely worn down, and metal is scraping against metal. This can quickly destroy your rotors and compromise braking power.

Rattling, on the other hand, can come from loose parts in the exhaust system, suspension, or undercarriage. Over time, bolts and heat shields can vibrate loose, leading to consistent rattling noises when driving over bumps.

Both grinding and rattling noises should be inspected urgently. Ignoring them could turn a small repair into a full replacement job and leave you stranded needing emergency towing.

Hissing or popping noises...Hissing noises usually indicate something is leaking or overheating. You might hear a hiss after shutting off your engine, which can be a sign of coolant or oil escaping onto hot engine components. If left unchecked, this can lead to overheating and engine damage.

A popping or crackling sound coming from your exhaust system may point to unburnt fuel igniting in the tailpipe. Many drivers ask, “Why is my car making crackling noises?”, and often it is due to exhaust leaks, misfiring spark plugs, or a failing catalytic converter.

If you notice these car exhaust noises, have a professional inspect your exhaust system immediately. A damaged exhaust not only affects performance but can also increase harmful emissions and fuel consumption.

Metallic knocking from the engine...One sound that should never be ignored is a deep, metallic knocking from the engine that varies with engine speed (RPM). Such a sound may indicate worn crankshaft bearings or other internal engine components. Continuing to drive can lead to serious damage or even total engine failure.

A different type of problem can be identified by a metallic rattling sound when starting a cold engine.

In cars with a timing chain, this noise may indicate a worn chain, tensioner, or guides. If the rattling lasts longer or persists even after the engine has warmed up, you should not delay a visit to the mechanic. Whistling doesn't always mean a turbo problem.

A whistling sound that gets louder when accelerating often raises suspicions of a turbo failure. Damaged turbocharger bearings can indeed produce a distinctive whistle, sometimes resembling a siren.

However, the cause could also be a cracked air intake hose, a faulty connection, or another issue within the pressurized air intake system.

If the whistling is accompanied by a loss of power, exhaust smoke, or increased oil consumption, there is a higher probability that the problem is serious.

A humming sound that intensifies with speed...A deep humming or whining sound that grows louder as the car accelerates often indicates a worn wheel bearing. Characteristically, the sound may change when turning, as the load shifts from one side of the car to the other. However, unevenly worn tires can also produce similar sounds.

If the noise changes based on vehicle speed rather than engine RPM, you should check the wheels, tires, bearings, and drivetrain.

In all-wheel-drive vehicles, a whining sound coming from the middle or rear of the vehicle could indicate a problem with the differential or the transfer case.

A clicking or popping sound when turning...A rhythmic clicking or popping sound during sharp turns—especially when applying slight throttle—is often a sign of a worn constant-velocity (CV) joint. This problem most commonly occurs in front-wheel-drive cars. If the fault is detected early, replacing the joint or the half-shaft is usually sufficient.

However, ignoring the problem can lead to total joint failure and a loss of power transmission to the wheel, rendering the car immobile.

Squeaking and scraping during braking...A high-pitched squeak during braking can be caused by worn brake pads, but also by moisture or surface corrosion.

A much more serious sign is a harsh metallic scraping sound. This may indicate that the brake pads are so worn that their metal backing is already scraping against the brake disc. In such a case, a relatively inexpensive pad replacement can turn into a much costlier repair that also requires replacing the discs.

If the car also vibrates during braking or pulls to one side, the braking system should be inspected as soon as possible.

Clunking sounds when driving over potholes...Dull thuds when driving over bumps can have various causes. The problem could lie with the stabilizer links, rubber bushings, ball joints, shock absorbers, or their mounts. Although some of these parts are not particularly expensive, neglecting the issue can impair the car's handling and accelerate wear on other components.

Particular attention should be paid to clunking sounds that occur during turning or braking, as they may indicate problems with components that affect wheel alignment.

Belt squealing is not always harmless...A brief squeal from the belt after starting a cold engine can be caused by wear or an issue with the tensioner. However, continuous squealing can also indicate a fault with the alternator, the air conditioning compressor, or one of the pulleys. If the belt snaps, the consequences depend on the engine design.

In the best-case scenario, the car might simply lose battery charging or air conditioning functionality, whereas with certain engines, the damage can lead to much more serious problems.

Recognizing the change is key...While sounds can serve as a useful warning, no serious mechanic would make a definitive diagnosis based solely on what they hear.

Different faults can produce similar sounds, and it is not always easy to pinpoint the exact source of the noise while driving. That is why it is crucial to be familiar with your car's normal sounds and to take action when something unusual occurs.

Metallic clunking, a continuous whine, scraping, or whistling accompanied by a loss of power are reasons to have the car inspected as soon as possible. A timely response can make a huge difference between a relatively simple repair and a breakdown that could cost the owner several thousand euros.

Strange noises coming from your car are often early warning signs of a worn-out part; if ignored, they can turn a simple repair into a costly breakdown.

Key noises and the risk of high repair costs:

• Squealing or metallic sound when braking: Indicates worn brake pads. If you keep driving, the metal scrapes against the disc, destroying the rotors and requiring a replacement of the entire braking system.

• Creaking or squealing from the engine (belts): Points to dried-out or loose accessory belts (such as the alternator belt). If a belt snaps, it can cause the engine to overheat or cut off power steering, leading to severe engine damage.

• Popping or clicking sound when turning the steering wheel: Signals a failure in the CV (constant velocity) joint or axle. If it breaks completely while the car is moving, you lose traction and damage other suspension components.

• Metallic knocking or clicking from the engine (ticking or "pinging"): Usually associated with low oil levels or lubrication failure in the valves and lifters. Without oil, metal-on-metal friction can fuse internal engine parts together, requiring an engine rebuild or complete block replacement.

• Low-pitched rumbling or roaring from the wheels: Indicates a worn wheel bearing. If the bearing seizes while driving, there is a risk of losing control or the wheel detaching.
