2024 Polestar 2 Preview



Once Volvo’s performance and racing arm, Polestar has split into its own entity. The company builds futuristic electric vehicles (EVs) with minimalist Scandinavian styling and great tech. Its second model, aptly named the Polestar 2, is now a few years old and due for a refresh. It’s getting the update for the 2024 model year, which the automaker says brings more power, a more extended range, sustainability improvements, and an available rear-wheel-drive (RWD) variant.

The Polestar 2 comes in four primary configurations: Long-Range Dual-Motor with Performance Pack, Long-Range Dual-Motor, Long-Range Single-Motor, and Standard-Range Single-Motor. Though Polestar improves the EV’s range for 2024 (up to 395 miles in some models), charging speeds remain stuck at 205 kW—a bit slower than Tesla’s supercharging speeds and behind rates advertised by other automakers.

What’s New for the 2024 Polestar 2?

  • Revised powertrains and more range
  • Available RWD variant
  • Focus on sustainability improvements to reduce the carbon impact
  • New standard safety tech
  • Now available for order in European countries
  • Pricing starts at around $55,000

The Polestar 2’s exterior didn’t receive significant updates for 2024, but the addition of SmartZone safety equipment is a notable change. Mounted in the front fascia, the space houses sensors and equipment that enable driver aids. Other changes include 20-inch forged alloy wheels in the Performance pack, which Polestar says more closely reflect the upcoming Polestar 3’s sporty attitude.

2024 Polestar 2 Interior

The 2024 Polestar 2’s interior will likely carry over from its predecessor. That means standard vegan materials and a striking Volvo-like design. Though vegan, the seats have a premium leather feel and offer attractive designs perforated into the fabric. Polestar tastefully integrates wood and other natural fibers, and the overall interior look is one of minimalism.

The new Polestar 2 gets revised electric motors and inverters that the automaker says improve efficiency and performance. The single-motor models now come in RWD and offer 295 horsepower and 361 pound-feet of torque. Polestar states a zero-to-62-mph time (0-100 km/h) of 6.2 seconds.

Dual-motor Polestar 2s now have a rear bias, which, according to the automaker, gives them a livelier, more engaging feel on the road. Polestar says the rear motor is the primary drive source. System output climbs to 416 hp and 546 pound-feet of torque. The front motor can shut off when not needed to improve efficiency, but when the whole system is active, acceleration to 62 mph from a standstill takes a claimed 4.5 seconds.

The new 2 also offers more range than its predecessor. Long-range battery capacity is now 82 kWh, and standard-range models get a 69-kWh battery. The range for the Long-Range Single-Motor model now extends to 395 miles, and the Long-Range Dual-Motor variant offers a solid 368 miles of range. It’s worth noting that these numbers were calculated using the WLTP standard, which is usually more generous than similar estimates put out by the EPA.

2024 Polestar 2 Safety

Volvo heritage means Polestar is a brand focused on safety. Neither the National Highway Traffic Safety Administration nor the Insurance Institute for Highway Safety has rated the crashworthiness of the Polestar 2, but the EV’s standard equipment list is generous. New advanced driver assistance systems will become standard in 2024, including blind-spot warning with steering support, rear cross-traffic warning with brake support, rear collision warning, and a surround-view camera system.

The car also gets Polestar’s SmartZone safety sensors. The array is located in the front fascia and includes two radar systems, a 3D camera, and more. As part of the package, the car gains sensors in other locations around its exterior.

2024 Polestar 2 Technology

Polestar provides a 12.3-inch digital gauge cluster and an 11.2-inch touchscreen. The system runs Google Android Automotive OS, which brings built-in services from the tech giant and advanced voice controls for climate settings, audio features, maps, and more. Polestar also added a full-scale web browser that offers legitimate web surfing with streaming and other features available.

Spotify, Apple CarPlay and Android Auto, Google Maps, and an integrated parking pay/location app come standard. If more than one passenger has a Spotify playlist, the Polestar 2’s Group Sessions feature allows anyone in the car to add music.

2024 Polestar 2 Competitors

The Polestar 2 competes most closely with the Tesla Model Y. The Polestar is cheaper and offers a better interior with more features, but Tesla wins in key categories, including acceleration and electric efficiency. Buyers may also consider the Audi Q4 E-tron, Tesla Model 3, or Volvo C40 Recharge.

Polestar is the source of information in this article. It was accurate as of January 24, 2023, but it may have changed since that date. Always confirm product details and availability with the automaker’s website or your local dealership.

A Quick Guide to Better CMM Maintenance




A coordinate-measuring machine, also known as a CMM, is a specialized piece of equipment common in high-precision manufacturing. It uses coordinate technology to measure and replicate the dimensions of particular objects.

CMMs are a lot more accurate than regular measurement gauges. This characteristic makes them the equipment of choice for quality assurance in certain industries, like aerospace, defense, and medical manufacturing.

Despite being a powerful piece of equipment and the most versatile measuring tool in the metrology industry, CMMs can also be quite delicate. They require the right environment and proper maintenance practices to maintain accuracy and reliability.

The Importance of Proper CMM Maintenance

It’s essential to clean and inspect each part of your machine to ensure it stays efficient and accurate. Preventative maintenance ensures that your CMM remains accurate and performs at its best. It also improves your machine’s longevity.


Without proper CMM maintenance, you could risk damaging your CMM. Repairs would involve operational delays and additional costs.

CMM Preventative Maintenance Tips

Preventative maintenance practices are ones your team could do by yourselves. It’s best to schedule regular maintenance checks for your CMM daily, weekly, monthly, or quarterly. These checks can alert you immediately to possible problems with your CMM.

Remove dust and dirt regularly

Clean and well-maintained air bearings ensure your CMM works as it should. These frictionless and stable bearings help ensure accuracy and efficiency. Dust and dirt can clog your machine’s air bearings, affecting its overall performance.

Aside from your machine’s air bearings, dust could also get into other surfaces and crevices. These tiny particles could affect your machine’s accuracy.

Handle Stylus Tips Properly

The stylus is the tip that makes contact with the object you want to measure with your CMM. Despite this significant role, the stylus can be fragile and require careful handling. Too much force could cause it to bend or break.

Clean your stylus with a cleaning agent and a lint-free cloth. Make sure to remove any residue from workplace materials.

Ensure Good Air Quality

Most CMMs use air bearings, and good air quality is essential to keep them running smoothly. Various air quality issues could affect machine performance and even burn out machine motors.

For air quality maintenance, ask and address the following questions:

  • Do the lines have condensation, oil, or other contaminants?
  • Is the airflow constant?
  • Are you using the proper pressure?

When To Call a Professional

Most preventative maintenance practices are simple enough to be performed internally. However, some issues require professional attention. You can also conduct regular professional maintenance checks to ensure you don’t miss anything.

Below are some procedures that require professional assistance. Many CMM suppliers also offer maintenance services alongside their machinery.

Conducting CMM Training

CMMs are highly specialized pieces of equipment. To handle them properly, your staff needs professional training.

Training courses allow you to get trained by CMM experts on the tools and knowledge necessary within your industry. Regular training sessions also help keep you updated on industry trends and standards.

Sensor Malfunctions

CMM sensors are critical to your machine’s speed and accuracy. They should be professionally inspected and calibrated annually.

Routine sensor maintenance can significantly improve the efficiency and accuracy of your machine. CMM sensors include the following:

  • Scanning probe
  • Single point laser
  • Line laser
  • Electronic touch trigger probe
  • Video camera

Faulty Bearings

Neglected air bearings could cause them to falter in their accuracy and stability. Properly maintained air bearings ensure a smooth, stable, and accurate measurement process.

A professional metrology company can thoroughly inspect your air bearings to prevent further machine damage.

A CMM is a significant investment for any business. Good maintenance practices help your machine last and perform at its best, thus making the most out of this investment.

Nintendo’s discounted Switch game vouchers are back



Nintendo’s Switch Online service has become a better deal over time, offering more perks than just the ability to play games online. On top of getting access to SNES and NES classics, and cloud save backups (for most games, save a couple dozen), Nintendo announced an even bigger perk yesterday: discounted game vouchers.

All subscribers can buy a two-pack of these vouchers for $99.98, and a huge range of first-party (in other words, typically discount-averse) Nintendo games are looped in. I encourage you to check out the full list, but some highlights include the brand-new Fire Emblem Engage, Kirby’s Return to Dream Land Deluxe, Bayonetta Origins: Cereza and the Lost Demon, Metroid Dread, Splatoon 3, The Legend of Zelda: Breath of the Wild, and Pokémon Scarlet and Violet. Important note: you both have to be a subscriber to buy and use these vouchers.

It’s great that this list is more expansive than Nintendo’s first swing at this deal in 2019. But this perk could actually turn Switch Online into a must-have service because it allows you to pre-purchase up to four sets of vouchers (totaling eight games), and keep them for 12 months from the date of purchase. With $20 in savings with each pair of vouchers, buying four bundles will save you up to $80, assuming that each title normally costs $59.99. If you buy a lot of games, this is a smart way to save a little bit of money on every forthcoming purchase.

I know what you might be thinking: “Can I use one on The Legend of Zelda: Tears of the Kingdom?” Nintendo has not currently listed the deliriously anticipated sequel to Breath of the Wild, which is set to release on May 12th, 2023. Polygon has reached out to Nintendo to see if it’ll eventually become eligible, but did not hear back in time for publication.


You can get a free seven-day trial for Switch Online here, and you can easily subscribe to the service directly from the Switch’s eShop (it costs $3.99 per month, $7.99 for three months, or $19.99 per year). However, you can purchase (or gift) a one-year subscription with a digital code via Best Buy for $19.99. With a family subscription that costs $34.99 per year, up to eight Switch accounts can reap the perks of Switch Online.

For players who want all the perks, access to Goldeneye 007 and other N64 and Sega Genesis games, and complimentary DLC for some Switch games like Mario Kart 8 Deluxe, you’ll need Nintendo’s Switch Online plus the Expansion Pack tier, which costs $49.99 per year for one account, or $79.99 per year for a family subscription.

Canadian discovery could help batteries last longer



A chance discovery in a Canadian laboratory could help extend the life of laptop, phone and electric car batteries.

According to scientists from Dalhousie University in Halifax, common adhesive tape in batteries may be the reason many devices lose some of their power while off or not being used, which is a phenomenon known as self-discharge.

“In our laboratory we do many highly complex experiments to improve batteries, but this time we discovered a very simple thing,” Michael Metzger, an assistant professor in Dalhousie University’s physics and atmospheric science department, said in a news release. “In commercial battery cells there is tape—like Scotch tape—that holds the electrodes together and there is a chemical decomposition of this tape, which creates a molecule that leads to the self-discharge.”

The solution is simple, too, Metzger says: replace the polyethylene terephthalate, or PET, plastic tape commonly used inside batteries with something more durable and stable.


“It’s a commercially relevant discovery,” Metzger said. “It’s a small thing but it can definitely help improve battery cells.”

Metzger and his team have been trying to understand why lithium-ion battery cells in inactive devices tend to lose some of their power and self-discharge, something that has long frustrated consumers and manufacturers alike.

“Every manufacturer of lithium-ion cells in the world wants to make self-discharge as small as possible,” Metzger told in a joint statement with graduate student Anu Adamson. “In every battery there is a small rate of self-discharge that slowly drains the battery. This is very inconvenient for users and a big headache for industry.”

The electrodes that power batteries are separated by an electrolyte solution that is usually a form of lithium. After exposing several battery cells to different temperatures, researchers were surprised to see that electrolyte solution had turned bright red when it normally should be clear, which was something they had never encountered. The discovery was made by Adamson and two other students.

Chemical analysis of the red electrolyte solution revealed that at higher temperatures, a new molecule had been created inside the battery through the decomposition of common PET adhesive tape, which is often used to hold components together inside batteries. Strong and lightweight, PET is also frequently used for plastic packaging, drink bottles, clothing fibres and more.

Researchers realized that the red molecule, dimethyl terephthalate, was acting as a redox shuttle, meaning that it can transport electrons between a battery’s positive and negative electrodes, creating self-discharge and depleting power even when a battery is not in use. Ideally, the shuttling of electrons within a battery should only happen when a device is on.

“It’s a very simple thing—it is in every plastic bottle and no one would have thought that this has such a huge impact on how the lithium-ion cells degrade,” Metzger said in the news release. “It’s something we never expected because no one looks at these inactive components, these tapes and plastic foils in the battery cell, but it really needs to be considered if you want to limit side-reactions in the battery cell.”

The findings are outlined in a pair of studies published on Jan. 20 and Jan. 23 in the peer-reviewed Journal of The Electrochemical Society. The researchers are now testing PET tape substitutes.

“Since the PET in the tape is the culprit that creates the redox shuttle, we need to replace it with a polymer that is more stable and does not decompose in the harsh chemistry of a lithium-ion battery,” Metzger and Adamson told “So far, the results look very promising, and we plan to publish a new research paper on improved polymers for lithium-ion battery tapes soon.”

According to the researchers, their work has been attracting interest from “some of the world’s largest computer hardware companies and electric vehicle manufacturers,” which are eager to reduce self-discharge and improve battery performance.

“We visited some of these companies and they are planning to implement more stable polymers in their battery cells,” Metzger said.

In the release, Metzger noted: “One of the engineers said, ‘I heard you guys found out something is wrong with PET tape.’ So, I explained to him that it’s causing this self-discharge and asked him, ‘What are you using in your cells?’ He said, ‘PET tape.'”
