2027 Nissan Rogue Hybrid: Drives like an EV, but there's no plug involved

2027 Nissan Rogue Hybrid: Drives like an EV, but there's no plug involved

Nissan has a new version of its bestselling Rogue SUV, and it’s launching the model here with the latest version of its e-Power hybrid system, which Ars tested in February. Most hybrid cars you can buy today are parallel hybrids, which means that they have an internal combustion engine and an electric motor, both of which drive some or all of the wheels—everything works in parallel. But there’s another approach. Instead of connecting the engine to the wheels via a transmission, it can act as a generator and charge the traction battery, which in turn powers the electric motor. Since the engine and motor work in series, this is known as a series hybrid.

That’s mostly how the Chevrolet Volt worked. As does Honda’s hybrid CR-V. Well, mostly; engineers worked out it was more efficient for those cars' gasoline engines to directly drive the wheels at highway speeds, something that to this day makes a certain subset of hybrid car enthusiasts irrationally angry. If you know anyone like that in your life, send them to wherever the nearest Nissan dealership is, because the 2027 Rogue Hybrid is exactly what they’ve been asking for.

Series hybrids

Under the hood, with its crisp shut line and slim horizontal lights that give me something of a Range Rover vibe, there’s a 1.5 L, three-cylinder turbocharged direct-injection engine that generates 148 hp (110 kW). It only revs to 5,200 rpm because it’s optimized to charge the battery, not cope with the various loads of an engine connected to a gearbox and the wheels. That also allows the engine to operate at a rather impressive 42 percent thermal efficiency—we would need to look at Formula 1 engines to find higher.

Review: You Can See Everything blurs the view of Elizabeth Holmes' deceit

Review: You Can See Everything blurs the view of Elizabeth Holmes' deceit

In 2015, biomedical entrepreneur Elizabeth Holmes was Silicon Valley's golden girl, lauded as the youngest and richest self-made female billionaire thanks to the company she founded, Theranos, which was valued at $9 billion at the height of its success. Then it all came crashing down when accusations of fraud surfaced about the company's signature blood-testing device, culminating in a sensational trial. Holmes was convicted on four counts and sentenced to 11 years in prison.

Holmes is back in the headlines thanks to a new film, You Can See Everything, which depicts the final days before Holmes, having exhausted her appeals, went to prison. Co-directed by Nathan Fielder and Lance Oppenheim, it's a surreal, absurdist piece that has largely been received with gushing enthusiasm and no small amount of hype, with some declaring it the best film of the year. A few contrarian voices have emerged over the past week with much-needed reality checks, but there's no denying the film is destined to be an awards-season darling.

Pardon me for joining the buzzkills, but I cannot in good conscience jump on the You Can See Everything bandwagon. Sure, it has its moments, and the second half is highly entertaining, but there's nothing here to warrant all the breathless hyperbole. For all their much-touted access, Oppenheim and Fielder have produced a surprisingly shallow film that runs in circles, yielding very little fresh or novel insight—into Holmes, personally, or much else.

Rocket Report: Winter is coming for Themis; Cowboy Space adds iron to the fire

Rocket Report: Winter is coming for Themis; Cowboy Space adds iron to the fire

Welcome to Edition 9.17 of the Rocket Report! It's been a while since an American company announced plans for a medium-lift new launch vehicle, but that's what happened this week when a startup named Cowboy Space revealed specs for its Big Iron rocket, named for the classic country-western song by Marty Robbins. I'm a huge fan of the name. Maybe Cowboy Space is striking while the iron is hot as the space industry frets over demand for launch outpacing supply. However, Cowboy Space lags far behind so many other launch providers nearing the launch pad with their medium-class rockets, and the company didn't have much hardware to show at this week's big reveal. In other words, don't mistake style for substance. But we're rocket fans at Ars, and we wish them luck.

As always, we welcome reader submissions, and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Virgin's new rocket plane reaches home port. The first of Virgin Galactic's new Delta-class rocket planes left its Arizona factory Wednesday for a trip to Spaceport America in neighboring New Mexico, where it will undergo preparations for a test campaign culminating in suborbital flights to the edge of space, Ars reports. Virgin Galactic expects the craft's first commercial spaceflight to take place "early" in the second quarter of 2027, but like every other projected date in aerospace, this should be taken with a grain of salt. Virgin Galactic halted commercial flights of its previous vehicle, VSS Unity, in 2024.

Reddit is moving to “a logged-in-only experience,” CEO says

Reddit is moving to “a logged-in-only experience,” CEO says

In the future, you won’t be able to use Reddit without logging in.

Reddit CEO Steve Huffman confirmed the impending change in a letter (PDF) to shareholders today about Q3 performance. He said that Reddit is shifting “to a logged-in-only experience," adding:

Moving to primarily logged-in will ensure our users have the best Reddit experience possible, and can find the content and communities most relevant to them. It is better for our business because we will have more signals for ads targeting, and being logged-in leads to higher engagement generally. It also allows us to protect access to Reddit’s extremely valuable corpus of data, and helps us better adapt to emerging regulations around the world.

Huffman also said that the login requirement will help Reddit better retain new users.

Microsoft fixes a Windows 11 annoyance as PC revenue declines

Microsoft fixes a Windows 11 annoyance as PC revenue declines

Microsoft is beginning the rollout of a Windows 11 preview update that finally addresses a persistent power user complaint with the operating system: the right-click menu that obliterated years of muscle memory on command locations and hid others behind an additional click. The timing is notable, as the announcement comes alongside Microsoft's quarterly financial report, which showed a continued decline in the business of selling Windows licenses for new PCs.

The preview update, KB5127936, is cumulative for Windows 11 versions 26H2 and 25H2. The update will be a gradual rollout before eventually moving on to a normal rollout for all Windows 11 devices once it reaches general availability. The highlight of the new update should calm annoyed users who have spent years with custom scripts and services in an attempt to shape Windows the way they would prefer it. Users will get a "customize menu" button that controls what commands appear when they right-click their mouse. Users can toggle built-in commands such as Send To or Create Shortcut on or off, rearrange what appears on the main menu, and control which third-party extensions show up in either the main or submenus. The gripe with the right-click menu had been that Microsoft hid familiar command locations behind a top row of icons while moving other familiar commands under the "Show more options" submenu. Now, Windows users can customize the whole thing around their habits.

The new preview also highlights a new Windows feature called Cloud Rebuild, a recovery option that can reinstall Windows 11 directly from the cloud, even when an existing Windows 11 fails to boot. Cloud Rebuild will pull the Windows 11 image and needed system drivers directly from Windows Update. Users will not need a custom recovery image or external media to reinstall Windows. There is an important distinction to note, however. Microsoft classifies Cloud Rebuild as a recovery option, but it behaves more like a fresh Windows install than a repair, as existing applications and files will not be included. Those worried about data security can sanitize entire system drives prior to reinstalling. For a full list of improvements coming to Windows 11, including changes to Xbox mode and settings, you can view the official Microsoft release announcement.

Pentagon IG refuses to investigate Starlink/Starshield slowdown in Ukraine

Pentagon IG refuses to investigate Starlink/Starshield slowdown in Ukraine

The Pentagon inspector general's office declined a request from US senators to investigate restrictions recently imposed on the Ukraine military's use of SpaceX's satellite network.

Ukraine, which uses SpaceX's Starlink service and the military version known as Starshield, said earlier this month that military drones lost satellite connectivity when traveling above 161 kilometers per hour (100 miles per hour). The limit was removed after about 10 days.

Five Democratic and four Republican senators sent an October 15 letter to Department of Defense Inspector General Platte Moring, asking for a probe into the reported disruptions of Starlink and Starshield. The letter asked, among other things, "whether any restrictions on Starlink or Starshield services were directed, authorized, or implemented by SpaceX, the Department of Defense, or other US government entities; whether such restrictions were consistent with applicable US government contracts, and what actions, if any, the Department of Defense took in response."

Turning a solar power system into its own backup

Turning a solar power system into its own backup

Rather than directly converting photons into electricity, concentrated solar energy uses mirrors to turn sunlight into heat, which can then be used to drive traditional generating turbines. Up to about a decade ago, there was a case to be made that concentrated solar energy had a bright future, as improvements in heat storage had turned it into a way to generate power around the clock.

It wasn't to be. While concentrated solar costs fell enough to compete with nuclear power, the price of photovoltaics plunged, making solar panels the cheapest source of power in most locations. Currently, if you have a good site to generate solar power, then the economics of PV panels are hard to beat.

That has left us needing to build a mixture of other facilities—typically batteries and natural gas facilities—to handle overnight needs or weather-driven shortfalls. But a small company is promising that it can help avoid the need to build a separate facility. Its version of concentrated solar is designed so that a fossil-fueled backup system shares most of the generating hardware with the solar side.
