Test Driving The Porsche Panamera Turbo S E-Hybrid
Providing the conclusion at the start for those who only like to browse, here goes: within the confines of possibility in a heavily regulated industry, the Panamera Turbo S E-Hybrid is as close as a high-performance 4-door can be to perfection. They have killed my job here: nothing to complain about, nothing to debate with my grumpy engineer pals…nothing.
Power is always the heart of the story, and Turbo S E-Hybrid does not disappoint.
Panamera's Turbo S 4-liter twin-turbo V8 produces 591 horsepower at 6500 rpm, and 590 lb. ft. of torque between 2400 and 4500 rpm. That's 79 horsepower more than the next most potent Panamera, the Turbo E-Hybrid. It feeds through Porsche's dual-clutch gearbox and all-wheel drive system.
Ahh, but then we add the 331 lb. ft. of instant torque of the electric motor and Porsche's hybrid math totals are 771 horsepower at 6000 rpm, and 737 lb. ft. between 1860 and 5260.
Let's give that number perspective. The electric motor sandwiched into the transmission housing adds exactly the same amount of torque, instantly, as produced by the 4-liter flat-6 engine of the Porsche 718 Spyder RS, a car I consider one of the world's finest pure sports cars. That's a whole lot of torque fill-in at launch and into the lower and middle rev range.
Beyond the phenomenal power, one is never truly aware of the electric motor, unless using the Hybrid or EV calibration settings. In Sport and Sport+, you hear and feel the V8, but there's no sense of a 'hand-off' with the electric motor. Porsche, like the best car companies, has seamlessly integrated the two powerplants, gas and electric.
I defaulted to Sport for most driving because I love V8s but found the EV setting far better than adequate on boulevards and residential streets, and I truly enjoyed it. Funny, but I either wanted lots of gasoline power to easily blast by anyone, or Full Gattaca in EV mode, which allowed Panamera to glide in near silence with easy acceleration. EV is not a hair shirt experience. I found it soothing when I had a thought-knot in my head.
Notice how the range of maximum available torque widens dramatically when the electric motor is factored in? It's nearly impossible to catch this car flat-footed or outwitted when streaming on a lonely midnight highway or a mountain 2-lane. Turbo S E-Hybrid just never, ever runs out of oomph, making it an utter delight for long-range travel covering hundreds of miles in a day, or for that mind-clearing blast up a favorite onramp.
At least since the age of the hot rod in the 1950s, standing start quarter mile and then 0-60 mph acceleration times have been key performance measurables in America, even if such antics can be incredibly hard on the equipment.
Here, Turbo S E-Hybrid stands without caveat amongst all supercars, able to wallop pretty much any cars short of the most outrageous 2-seat hybrid super sports cars. Never mind the generous cargo hold, long wheelbase, comfortable rear seats and hefty curb weight of 5311 lbs.
Set to Sport+, Turbo S E-Hybrid delivers a 0-60 mph sprint in 2.8 seconds—yes, under 3 seconds. Such launches are hard on the powertrain, and I only perform them once or twice on any given test car, to see how the computers and the mechanical bits play together. Otherwise, I perform roll-ons from 4 or 5 mph to save the gearbox, clutches and all those joints and shafts.
The other classic measurable in America is the standing-start quarter mile. Turbo S E-Hybrid does it in…drum roll…10.8 seconds. Yes, a sport-luxury 4-door 4-seat sedan rips the quarter mile in the tens. Unless you've experienced that sort of acceleration, little can explain just how quickly the verge of the road in your peripheral vision begins to blur, how the world starts to narrow to that point on the horizon where you are aiming the prow of your craft. Suffice to say, only the most radical hybrid 2-seat supercars and pure EV hypercars like a Porsche Taycan Turbo S or Taycan Turbo GT will have the drop on you, ever.
Excepting street racing moments, it's roll-on performance that matters, the ability to easily overtake dawdlers, the ability to hole-shot, that slingshot sensation accelerating out of a tight corner. Turbo S E-Hybrid can rush from 15 or 20 mph to 60, 70, 80 or 90 mph in a breath or three. Turbo S E-Hybrid can shoot from a highway speed of 70 to triple digits in a mere moment.

Where does that performance pay dividends? When overtaking a freight train of 2 or 3 Class 8 big rigs hauling loads of green tomatoes through our California Central Valley, or getting around a similar raft of gravel trucks on the 210 freeway in Los Angeles. Roll-on performance limits exposure during overtaking, allows one to dispatch lesser vehicles in moments.
Panamera turbo S E-Hybrid. The office.

Best proof of Turbo S E-Hybrid's phenomenal roll-on acceleration came some months ago. Porsche's Ace of the Nürburgring, Lars Kern, set a new 4-door hybrid record lapping the famous12.9-mile Nordschleife, crushing the existing Panamera record by 5.6 seconds. This is best proof of the Turbo S E-Hybrid's mighty powertrain. Such a significant reduction in lap time is due primarily to acceleration out of corners, leaping from 60 or 70 mph to 150 mph in mere moments, shrinking those straightaways. Of course, enormous brakes and huge sticky Michelins don't hurt, either.
Other side of that phenomenal performance on the Nordschleife is Turbo S E-Hybrid's incredibly well sorted active suspension, which more than makes up for the added weight and complexity by greatly limiting chassis roll when cornering by in essence holding up the outside wheels, keeping the car's cornering posture very flat. My video and photos of my hand in the wheel well shows the potential range of adjustment. In a right-hand corner, the electric pumps will increase pressure within the left-side dampers, which will push against the forces of physics to keep Panamera from heeling over too much or too quickly. In short, the left-side will be propped up with hydraulic pressure and the car will be kept in a flatter stance, a more assured stance.
Steering, and the weight and action of pedals, are flawless. Seating position for the driver and all three passengers are exceptional. Rear seats are best for people of median height, who will be able to manage a lengthy trip. Taller people might prefer nothing more than a cross-town jaunt.
In EV mode, Panamera works beautifully on boulevards, with ample power to flow with traffic. Panamera Turbo S E-Hybrid now also has a 25.9 kWh lithium-ion battery under the cargo floor, replacing the 17.9 kWh of the previous version.
This car will be around for a very long time. Due to governments who cannot commit to industrial policy, the best car companies are being forced to engineer gas, hybrid, EV and hydrogen fuel cell powertrains for years to come. For those of us who love piston engines, well, these are the best of times.
To repeat the conclusion given at the start, Panamera Turbo S E-Hybrid is as close to perfect as any car I've ever driven. Yes, it must exist within the framework of government regulations, which means it's heavier and larger than E-class sedans of 20 and 30 years ago. But if we accept the parameters imposed by regulations well, Panamera Turbo S E-Hybrid is about as close to perfection as we've seen in recent decades.

Lamborghini Temerario test drive: $380K hybrid supercar delivers mind-boggling performance
Lamborghini's (VWAGY) latest creation, the Temerario supercar, has some big shoes to fill. Let me rephrase that — the 900hp, all-wheel drive, plug-in hybrid Temerario with a 10,000 RPM turbo V8 has some big shoes to fill. Che cosa? That's because it's replacing the much-loved Huracán: the outgoing serpent-like, alien-looking creation equipped with a sublime, yet ferocious when needed, naturally aspirated V-10 engine. The Huracán was amazing. But times are changing. Around a year ago at Monterey Car Week, Lamborghini unveiled the Temerario, which loosely translates to 'reckless' in Italian. The long-in-the-tooth Huracán — which, believe it or not, is over 10 years old and shared some underpinnings with sister brand Audi's R8 — needed a refresh. Lamborghini also sold 30,000 units of the $250K+ Huracán, its best-selling car ever. In other words, it couldn't mess this up. And with changing rules like emissions and electrified propulsion needed in certain European locales, hybrid power was needed. Lamborghini knew it had to convince buyers this wasn't a 'green' thing — it's about performance. It did this convincingly with the Revuelto, its range-topping supercar that combines a V12 with a hybrid system, using electric motors more for performance than range. Switch Auto Insurance and Save Today! Affordable Auto Insurance, Customized for You The Insurance Savings You Expect Great Rates and Award-Winning Service Lamborghini's CEO Stephan Winkelmann notes the car is completely new from top to bottom, including, of course, the new powertrain. It has to be exciting, he says, but also livable. Lamborghini seems to have threaded that needle, at least for now: The car is sold out through its first year of production, he said, which is a nice start for the brand. The drive I took the Temerario on the track for a few sessions to put the car through its performance envelope. Styling-wise, it's a sleek, attractive car that fits the mold of what regular people envision when they think of a supercar. It's wide, low-slung, and angular. Not as extreme as the Huracán, but sexy in its own right. The rear is more interesting, with its fully exposed V-8 engine out back and fenders with wide cut-outs exposing the car's bulging rear tires, a nod to motorcycle design. One area the Temerario vastly improves on the Huracán is the interior. Better materials all around, better infotainment and instrument cluster digital screens with nice animations —and more space owing to slightly larger dimensions. Fewer buttons is not a welcome change, though it seems most of these functions are now controls on the steering wheel. On the track is where it all comes together. With its hybrid system, the Temerario features two motors powering each front wheel individually, giving the car true torque vectoring. That means the wheels can spin and apply force independently on their own. This also means that, while the rear wheels are powered by the monster V8, the front wheels can provide force at different times, like during an aggressive turn, keeping the car's line true and giving extra assistance around corners. Traction is of course improved as well. So handling-wise, the car feels a lot smaller than it really is, which makes even the most aggressive track easier to deal with. But true heart of the beast is its twin turbo, flat-plane-crank V8 motor. Combined with the two motors up front and one sandwiched in between the 8-speed transmission, the Temerario has a mind-boggling 900hp on tap. The engine alone is a marvel, able to spin up to 10,000 RPM. It is designed to keep pulling to that red line. Usually, most motors will start petering out at those heady levels. This allowed the Temerario to hit ungodly, panic-inducing speeds on the straightaways of nearly 200mph, which then meant going hard on the brakes, and then into the next curve without losing it. Those front motors really helped get the car back on the proper race line if you braked too deeply into the first turn, for example. The car allowed me to string faster lap after faster lap in succession, giving me confidence to push harder into every turn, and brake later. Yes, it is overall a better car than the Huracán when it comes to aggressive track driving. And I'm sure it's a perfectly livable car too — meaning, in theory, you could take it around town to run some errands — though I didn't get the chance to drive on local roads. But I have a few complaints, believe it or not. The loss of the Huracán's V10 really hurts from an emotional point of view — the sound of the 10-cylinder revving higher is intoxicating. Yes, the Temerario at 10,000 RPM screaming down the straightaway does give you that emotional kick, but most owners will not be pushing the car anywhere near that mind-boggling limit. Most owners will be driving around town or on some nice backcountry roads. And though I said it was subjective, the styling for me is a bit too toned down too, at least compared to the outgoing Huracán. For a car that starts at $382,654 in the US, we would like more of a wow factor. Lamborghini isn't done with the Temerario Lamborghini won't sit idly when it comes to special or updated versions of the Temerario. Performance models with aggressive styling and enhancements to the powertrain may mean more exciting versions could be coming. This is all part of the game plan. And some buyers actually prefer the base models of Lamborghini's creations because they are the purest form of these vehicles. But, finally, I have to ask: Could we see a Temerario special edition combining a non-turbo screaming V8 with those trick electric motors up front, or one with an aggressive, race car-like aero package?

The AI 'algorithmic audit' could be coming to hotel room checkout
Artificial intelligence can lead to surprises in all sorts of places where a bill once would have been considered settled. The use of AI by Hertz (and European car rental company Sixt) to scan for damage on cars, which is then charged to the customer, is a new application of the technology that is creeping into consumer life unnoticed. But it won't be the last unexpected adjustment to the travel experience courtesy of AI. Experts say consumers should expect to see businesses across the service industry deploying similar technology in the future, if they aren't already. "As businesses seek to automate loss prevention and operational efficiency, we're witnessing the emergence of what I call 'algorithmic auditing' – the systematic deployment of AI to identify, classify, and monetize previously overlooked inefficiencies or losses," said Shannon McKeen, professor of the practice and executive director for the Center for Analytics Impact at Wake Forest University School of Business. The Hertz program, recently reported on by the New York Times, is the beginning of what McKeen describes as a broader transformation, and new fault line, in the service economy. "The implementation of these systems reveals a fundamental tension between operational efficiency and customer satisfaction and equity," McKeen said. The question isn't simply whether AI can detect a scratch on a rental car bumper. "It's whether businesses should charge customers for every microscopic imperfection that algorithms can identify but human judgment might reasonably overlook as normal wear and tear," he said. McKeen says the dialogue between service agent and customer over costs will increasingly include a new term: "the machine says." Hotels are working their way through these changes, according to Jordan Hollander, cofounder of a research platform that helps hotels find new digital and AI products to improve efficiency. "I've been seeing more hotels experiment with AI across operations, but not quite in the same way Hertz is using it for automated damage detection and billing. That said, we're not far off," Hollander said. Some hotels, for instance, are already using AI-powered sensors to monitor air quality and trigger fines for smoking or vaping in rooms. But Hollander warns that sometimes the sensors trigger false positives. "Like someone using a hairdryer or aerosol spray — and guests get hit with $500 charges without ever lighting up. It's not hard to imagine how that could go south quickly," Hollander said. But unlike the car rental example, most hotels haven't automated the billing step yet. "They're using AI more to flag potential issues — like a room that smells off, linens that don't meet standards, or maintenance problems — and then looping in a human for the final call," Hollander said. For now, the AI is acting more like a very observant assistant than a judge and jury. "But it's clear that hotels are heading in the same direction," he said. "Between computer vision that can detect damage or wear in a room, and AI that analyzes guest behavior or room conditions in real time, the tech is already there." In a hospitality industry where trust is everything, there are reasons for hotels to move with caution. To date, many hotel operators are using AI to improve things like housekeeping efficiency, energy usage, and guest messaging — but they're being cautious about when and how it impacts the guest directly in a way that can be perceived to hurt the experience. "There's a risk of backlash if hotels start billing guests based solely on what an algorithm says. The moment a guest gets a charge and can't get a straight answer about why or how it was verified, you're in dangerous territory," Hollander said. "If guests feel like they're being watched or nickel-and-dimed by a machine, it undermines the relationship completely," he added. Recent experience in the hotel industry provides at least one cautionary tale, according to Hollander, referring to a custom-modified Alexa for hotels. "Years ago, the hot thing was voice devices, and that never really took off for this reason," he said. A Hertz spokeswoman told CNBC that AI brings uniformity and consistency to the checkout process. "For years, vehicle damage inspections have caused confusion and frustration. The process was manual, subjective, and inconsistent, and that isn't good enough for our customers or our business," she said. She added that with digital vehicle inspections, Hertz is introducing "much-needed precision, objectivity, and transparency to the process – giving our customers greater confidence that they won't be charged for damage that didn't occur during their rental, and a more efficient resolution process when damage does occur." Of the 500,000 rentals scanned so far, more than 97% showed no billable damage, according to Hertz, and damage incidents are declining at scanner-equipped locations. The Hertz spokeswoman acknowledged that the new system is still a work in progress. "We know change of this scale takes time, and we're listening, learning, and improving every day. As we said from the start, our goal through this initiative is to enhance the safety, quality, and reliability of our fleet and to create a more consistent rental experience for our customers." AI excels at pattern recognition, but where it may fall short is with the nuanced decision-making that has historically characterized good customer service, according to McKeen. "What makes these systems particularly problematic is the erosion of contextual judgment," McKeen said. Traditionally, business relationships relied on human discretion to navigate gray areas like "when does a scuffed tire represent normal use versus chargeable damage? When does a hearty portion in a restaurant satisfy a hungry customer versus being wasteful?" Other companies will be watching Hertz closely to see how the AI experiment works out, he said, and then jump right in on the profit opportunity if it is determined that use of the technology won't drive customers away. The use of AI for cost recouping isn't widespread yet because companies have not figured out the balance between customer trust and implementing AI, and the benefit, so far, doesn't outweigh the potential loss in loyalty, said Chuck Reynolds, managing director at L.E.K Consulting and a member of the firm's digital practice. The key for companies to implement these cost recouping tools is transparency. "While the opportunity for AI is huge, organizations need to be thoughtful about embedding it as a copilot, not police or enforcer," Reynolds said. Sustomers will accept AI as part of the experience, he added, if companies are fair, visible, and design the AI experience with empathy. "AI has to have customer-centricity built into its core," Reynolds said, and companies have to keep a role for humans in the process to oversee and override the AI if necessary. "Organizations that do so without thinking through the entire process will have challenges with internal adoption and customer adoption," Reynolds said. Customers should expect to see more of the technology Hertz is deploying in different settings, according to David Rivera, professor of hospitality and tourism at Flagler College. In addition to hotels, the future could include restaurants using AI to itemize plates to ensure accurate billing. But Rivera says all of this is being done with the goal of operational efficiency rather than to punish the customer. Use of AI in hospitality is evolving from passive data collection to active use of real-time decision-making tools, Rivera said, and that includes things like monitoring your rental car or how much you are raiding the mini-bar in your hotel room. "The common thread is increased operational efficiency, enhanced guest satisfaction, and automation of traditionally manual tasks, with a layer of accountability and transparency for both guest and provider," Rivera said. Not everyone is on board with that view, however. "This trend is absolute overkill with AI solution capabilities," said Daniel Keller, CEO of cloud infrastructure company Influx Technologies, which provides data collection and data analysis tools. "This particular use of AI doesn't increase efficiency; it scrutinizes customers of small-margin service businesses looking to suck extra money out of guest experiences."

How Selling European Models Could Revive Nissan In North America
Although it's certainly not the most recent news, Nissan's financial struggles are still relevant as the brand rushes to bring out new products, aiming to turn around the Japanese automaker's reputation in North America and to get its balance sheets out of the red. What you may or may not know is that Nissan is partnered with French automaker Renault, and it was announced earlier this month by Fortune that Renault has seen $11.2 billion wiped off the face of the Earth just to cover Nissan's losses. Despite their recent troubles, Nissan's team is making a serious effort to get things back on track, and that all begins with the most important thing: their products. Throughout 2025, Nissan has been rolling out a freshly revamped model lineup, ranging from an updated 2026 Nissan LEAF EV to the burly new Nissan Armada, a full-size body-on-frame SUV with four-wheel drive and a twin-turbocharged V6. While Nissan's efforts to refresh and revitalize its lineup haven't gone unnoticed, it's also been glaringly obvious that the brand's product portfolio has a few notable gaps. Buyers and Nissan dealers alike have been urging Nissan to revive the iconic Xterra - a rugged off-roader SUV that once shared its platform with the Frontier pickup truck and competed directly with the Toyota 4Runner. As these overland-ready off-roaders have grown in popularity immensely, it seems like a major missed opportunity for Nissan, especially considering the fact that the Frontier itself received a major update not too long ago. However, I don't think the gaps in Nissan's lineup begin and end with the Xterra, and in fact, it seems there's an entire selection of models that Nissan could offer North American buyers, but simply doesn't. I'm referring to European models, such as those from Renault, Dacia, and even Alpine, which have achieved sales success and critical acclaim across the pond. I can't help but wonder why Nissan doesn't offer European models from its partner companies, which are sure to be popular with American audiences. Using generative text-to-image artificial intelligence, we take an imagined look at what rebadged models from Renault, Dacia, and Alpine could look like rebranded as Nissans for the North American market. These images are purely for speculative and entertainment purposes and in no way reflect any actual Nissan, Renault, Dacia, or Alpine products. Affordable yet rugged crossovers are all the rage right now–just look at Subaru's Wilderness models, Honda's Trailsport editions, and Toyota's TRD Pro versions. Even Nissan is chasing the rugged lifestyle buyers with its Rock Creek Editions and Pro 4X models, and bringing the venerable Dacia Duster stateside with a set of Nissan badges and an updated fascia could make the allure of a tough, utilitarian crossover more accessible to the market. In the United Kingdom, the Dacia Duster has a starting MSRP of just £19,380 (around $26,000 when converted to $USD), meaning Nissan could potentially offer a 130-horsepower mild-hybrid crossover with optional four-wheel drive to American buyers for under $30,000. If that sort of offer couldn't resonate with American buyers, I don't know what would. Additionally, Nissan could offer the Dacia's upgraded, full-hybrid power plant–the turbocharged 1.6-liter "Hybrid 140" powertrain, which delivers a combined total of 140 horsepower and around 150 lb-ft of torque to all four wheels. A Nissan-branded Dacia Duster could offer a rugged rival to the popular Subaru Crosstrek, albeit with mild-hybrid and full-hybrid powertrain options. Before the Rogue became the hot commodity it is today, Nissan sold the X-Trail–a boxy, camping-friendly crossover–all over the globe. It was even sold in North America, and was hugely popular in Canada and Mexico, but Nissan decided not to sell it in the USA for some reason. These days, the global Nissan X-Trail is really just the Nissan Rogue that we see (quite constantly) roaming the streets here at home, but I think there's still a market in North America for the type of vehicle that the X-Trail once was. Offering boxier proportions and a more rugged four-wheel drive system, the Dacia Bigster-based Nissan X-Trail could be to the Nissan Rogue what the Ford Bronco Sport is to the Escape, or perhaps what the Mazda CX-50 is to the CX-5. Available with either a 140-horsepower turbocharged 1.2-liter three cylinder, or a 155-horsepower 1.8-liter four-cylinder hybrid powertrain, the Dacia Bigster's mechanical guts might win over American buyers left untouched, but I think a more powerful beating heart, such as the 1.5-liter VC-Turbo three-cylinder found in the current Rogue (which makes a stout 201 horsepower and 225 lb-ft of torque), would be a much more suitable motor. For years, we've begged Alpine to bring the glorious, turbocharged, mid-engine sport coupe to American roads. Unfortunately, we've yet to see it bless our shores, but maybe Nissan could change that. Now might be the perfect time to do so, considering that Toyota is seriously considering reviving the MR2, and Porsche is converting its Cayman and Boxster models to fully electric powertrains, which will inevitably alienate many of their loyal buyers. A Nissan-branded Alpine A110 in North America could help fill the gap in this desirable segment, putting itself up against the likes of the Lotus Emira and a potentially upcoming Toyota MR2 using its 296-horsepower turbocharged 1.8-liter four-cylinder, mounted behind the cabin, and paired with a seven-speed dual-clutch transmission and rear-wheel drive. Adding the A110 to Nissan's American lineup might not make for a superstar sales success, but it would certainly liven up the image of a brand that was once a champion of fun, affordable sports cars. Perhaps, too, we could see the return of fan favorites like the Nissan Silvia, the Stagea 260RS wagon, and the Pulsar GTI-R. While Nissan dares to think outside of the box to get things back on track, perhaps also thinking inside the box might provide some much-needed help. Rebranding European products from the same brand umbrella is a strategy for automakers that seems as old as time itself, from General Motors selling Opels as Buicks and Saturns in the 2000s to Ford replacing the hot-selling Escape with the European-styled Ford Kuga. I'm rooting for Nissan, and I'm looking forward to seeing how the brand goes about turning things around and returning to profitability, but it'll be a long and winding road to get there. And hey, there's not much else you could ask for on a long and windy road than a mid-engine Alpine A110 ;). Copyright 2025 The Arena Group, Inc. All Rights Reserved.
