New data reveals concerning trend in Tesla's customer base: 'Very dangerous for the brand'
A new poll revealed that Tesla is faltering among people across the political aisle. Unfortunately for the brand, it's not the first time it has faced this kind of issue, with owners reporting embarrassment and disapproval of CEO Elon Musk's behavior. Semafor published data from the Electric Vehicle Intelligence Report that demonstrated Tesla's brand perception has diminished among self-described Democrats, Republicans, and Independents. After Musk aligned himself with Republicans, some people thought Tesla's popularity among them would increase. However, the poll showed the opposite, with Republicans 11% less likely to buy a Tesla now, according to Semafor. The survey of 8,000 consumers suggested that Musk's foray into politics may have harmed the brand. "What he's done by wrapping Tesla into his political adventures, and, now, misadventures is very dangerous for the brand," Evan Roth Smith of Slingshot Strategies said, per Semafor. The shift in public opinion may not seem like a big deal, but it could have impacts across the industry. For example, Battery Technology reported that some executives believed Musk's political activities could have inspired Republicans to try EVs. However, that didn't pan out, as the EVIR data displayed. Battery Technology also suggested that people may be more concerned about buying a Tesla because they don't want to be associated with Musk or fear repercussions such as vandalism. Another potential issue is that Tesla's decline in public favor could create a gap in the EV market, as described by the Detroit Free Press. Considering Tesla became an industry leader and common household name, that's a significant hole for other brands to fill. Building trust in EVs takes time, which means consumers may not want to switch to another manufacturer. As a result, fewer people may be interested in EVs, which could lead to less production of these vehicles, as NPR reported. Additionally, fewer EVs on the road means that more cars powered by dirty energy sources are releasing pollutants into the air. Do you think Tesla can bounce back from its recent struggles? Yes It depends on Elon's actions I don't think it's struggling Nope Click your choice to see results and speak your mind. With all that said, the EV market can continue to gain customers' trust. For example, one of the biggest barriers to owning an EV is cost, whether you're interested in a Tesla or the Nissan Leaf. Making these cars more affordable will be especially crucial when the EV tax credit expires in September, as CNBC reported. It may also be beneficial if manufacturers make charging easier or the government expands public charging facilities. In the meantime, if you're ready to switch to a hybrid or EV, research manufacturers and models to find the right option for your needs.

Researchers explore next-gen twin batteries that could solve concerning problem with EVs: 'A promising approach'
Electric vehicles are transforming transportation for the better, but producing their batteries comes with high costs — a trade-off that researchers at engineering firm IAV may have found a solution for. IAV, a firm focused on the future of mobility, has developed a twin-battery design that pairs two different but complementary chemistries to reduce the cost and environmental impact of manufacturing EV batteries, reported. Instead of relying on lithium-ion cells, the design combines sodium-ion (SIB) and lithium iron phosphate solid-state (LFP-SSB) batteries. SIBs are low-cost and easier to recycle, while LFP-SSBs offer long cycle life and strong energy density. The system reuses waste heat from one battery to optimize the performance of the other. Combining the two types creates an energy-saving system that could boost range and efficiency without the high costs of cooling, heating, or mining for lithium-ion batteries, according to IAV also designed and developed the new battery with minimal waste. Using COMSOL Multiphysics, IAV engineers were able to tweak parameters and simulate the batteries' real-world thermal, chemical, and mechanical behavior. This validated the effectiveness and efficiency of the battery system without the need for multiple prototypes, per which sped up development while slashing costs and resource waste. Jakob Hilgert, a technical consultant at IAV, considers the use of diverse cell chemistries "a promising approach to respond to market fluctuations and at the same time minimize system costs," per IAV is also exploring other innovations, like the use of bipolar technology to maximize volume utilization of lithium-ion batteries. There are also other companies pursuing similar breakthroughs. For instance, Watt Electric Vehicle Company is developing a solar-powered closed-loop production system. Other automakers are also investing in research and development for better EV chargers and infrastructure. If you were going to purchase an EV, which of these factors would be most important to you? Cost Battery range Power and speed The way it looks Click your choice to see results and speak your mind. Energy solutions like these can make EVs more affordable. They could help drive EV adoption, going far beyond the 17.3 million electric cars produced in 2024 alone. For drivers looking to save even more, pairing an EV with home solar can drastically reduce charging costs. Platforms like EnergySage make it easy to compare quotes from vetted vendors, and can help you save up to $10,000 while minimizing environmental impact. While there's no firm rollout date yet, IAV's approach could contribute to a smarter, cleaner, and more accessible EV future.

Best Cargo E-Bikes of 2025, Tested
Thanks to ever-improving electric motors and increasingly affordable battery power, e-bikes have exploded in popularity over the past few years. Having already tested electric scooters, we decided it was time to dip our toes into another corner of two-wheeled transportation. Instead of chasing speed this time, we kicked off our e-bike coverage with the utilitarian workhorses of the category: cargo e-bikes. After all, what better way to offset car usage than with the two-wheeled equivalent of a minivan? Over the past few months, we've logged countless hours and miles to find out which models look sharp, ride well, and offer the most real-world utility. Spoiler: There's no one-size-fits-all winner. But our roundup breaks down the standouts so you can find the cargo e-bike that best fits your needs. Things to Consider When Buying a Cargo E-Bike Motor Power Most cargo e-bikes come with motors rated between 250 and 750 watts. The higher the wattage, the easier it is to climb hills and accelerate when carrying heavy loads. More power can mean more weight and faster battery drain, so balance your needs with your riding style. Hub-Drive vs. Mid-Drive Hub motors are mounted in the center of the rear wheel and provide a simple, often more affordable setup. Mid-drive motors, by comparison, are located at the crank (where the pedals are). They generally have a more traditional-bicycle experience and feel more natural under load. Unfortunately, that normally comes at a cost, with mid-drive motors often costing a decent bit more than their hub-driven counterparts. Class 1, 2, or 3: Class 1 e-bikes offer pedal-assist up to 20 mph and are legal on most bike paths. Class 2 models add an accelerator control to let you ride without pedaling, also limited to 20 mph. Class 3 bikes bump pedal-assist speed to 28 mph, making them quicker on streets but sometimes restricted on multi-use trails. Cadence vs. Torque Sensors: A cadence sensor activates the motor when you start pedaling and provides an equal level of power (at any given pedal-assist mode) regardless of how fast you're actually pedaling. Torque-sensing motors, on the other hand, measure how hard you're pedaling and adjust power output accordingly. This offers a more intuitive response that can feel more natural compared to cadence-sensing systems. Although purists may disagree, we don't think one is necessarily better than the other—they simply have different feels and one might fit your needs and preferences better than the other. Weight Capacity Cargo e-bikes are built to carry stuff, but exactly how much varies widely from one bike to another. Many bikes support 300 to 400 pounds, while heavy-duty models can handle upwards of 500. Always check the total payload capacity (including rider and gear) to ensure you're riding safely. Range Based on our experience, expect around 30 to 60 miles on a single battery charge, depending on weight, terrain, and assist level. If you're planning long trips or regular heavy-duty use, look for models that support a second battery to double your range. Pedal-Assist Modes (PAS Modes) Most e-bikes offer three to five levels of pedal assist. These modes, sometimes shortened to PAS, let you choose how much help you get from the motor when pedaling or using the accelerator. More modes mean better fine-tuning of control over battery use and riding effort, while maintaining flexibility when trying to extend your range or battle that final hill before you get home. Comfort and Ergonomics Comfort is key when you're hauling people or packages. An adjustable and properly padded saddle, adjustable handlebars, and other components can make a big difference, especially on longer rides. Another thing you'll want to keep in mind is your height. Some bikes, such as those with step-through frames, might be better if you're on the shorter end of the spectrum, while taller people might want to prioritize bikes with taller handlebars and seating positions. Assembly and Maintenance Some e-bikes arrive nearly ready to ride out of the box. Others require tools, patience, and some elbow grease. Mid-drive motors offer great performance but put more strain on chains and drivetrains, increasing long-term maintenance. Consider local bike-shop support or mobile services if you're not a DIY type. Interface E-bike interfaces range from minimalist LEDs to full-color screens that show speed, range, and assist levels. Accelerator controls are another consideration you'll want to take into account. You'll almost only ever come across thumb lever or wrist-twist types, and there's no one-size-fits-all solution here. Some riders on our team preferred the thumb-lever design, while others preferred a twisting accelerator. Best Cargo E-Bikes, Tested
