Audi GT50 Concept Is a Five-Cylinder Fever Dream—and We’re Here for It

Audi doesn’t do anniversaries quietly. When the brand wants to mark a milestone, it tends to reach into its motorsport trophy case, pull out something loud and a little unhinged, and turn it into a rolling manifesto. The new Audi GT50 concept is exactly that—a one-off celebration of 50 years of Audi’s most distinctive mechanical calling card: the inline five-cylinder engine.

The GT50 comes from Audi’s Neckarsulm apprentices, a group that has quietly become one of the company’s most interesting skunkworks. Each year, they’re given the freedom to create a single, no-compromises concept that either honors a historic Audi or previews an idea the brand wants to talk about loudly without promising anything legally binding. Past efforts have ranged from the track-obsessed RS6 GTO—so convincing it later morphed into the production RS6 GT—to quirky deep cuts like a reworked NSU Prinz and an electric reinterpretation of the A2.

This time, the brief was clear: celebrate half a century of Audi five-cylinders. The timeline starts in 1976, when the second-generation Audi 100 debuted as the first mass-produced car to use an inline-five engine. It was an oddball choice even then, splitting the difference between fours and sixes, but it became a defining Audi trait—one that delivered a unique sound, strong torque, and a motorsport legacy that still echoes today.

In fact, Audi now stands alone. Other manufacturers that once flirted with the format—Volvo, Ford, Land Rover, Volkswagen—have long since walked away. Audi hasn’t. Today, the five-cylinder lives on in just one production car: the RS3. Naturally, that’s where the GT50 begins.

From there, things get delightfully extreme.

The apprentices have transformed the RS3 into a rolling tribute to Audi’s fire-breathing American race cars of the 1980s and ’90s, most notably the 90 Quattro IMSA GTO and the 200 Quattro Trans-Am. Those cars weren’t subtle, and neither is this concept. The GT50 adopts a blocky, almost exaggerated three-box silhouette, with flat planes and aero-first surfacing that looks pulled straight from a homologation special that never was.

Retro details are everywhere. The front grille nods to old-school Audi race cars, the bodywork is stripped of excess ornamentation, and the most eye-catching feature—by far—is the set of massive turbofan-style wheels. They’re ridiculous in the best possible way, channeling pure Group B and IMSA energy while making it clear this car is about heritage, not lap times.

Audi hasn’t released full technical specs, but the powertrain is familiar—and that’s the point. Under the skin sits the RS3’s 2.5-liter turbocharged inline-five, producing 394 horsepower and driving all four wheels. In a concept like this, the numbers almost don’t matter. The engine’s presence is symbolic: proof that the five-cylinder isn’t just a nostalgia act, but a living, breathing part of Audi’s identity.

And that identity isn’t done evolving. Audi is widely expected to further honor the five-cylinder next year with a more hardcore RS3 special edition, likely building on the existing Performance Edition. If rumors hold, it could eclipse the Mercedes-AMG A45 to become the most powerful internal-combustion hot hatch on the planet—a fitting mic drop for an engine layout that refuses to fade quietly into history.

The GT50 won’t see production, and that’s fine. Its job isn’t to fill order books—it’s to remind us why Audi’s five-cylinder matters in the first place. Loud, unconventional, and unapologetically Audi, this concept proves that sometimes the best way to celebrate the past is to turn the volume all the way up.

Porsche’s About-Face: The 718 Boxster and Cayman Are Getting Their Gas Back

By any measure, this is one of the most dramatic drivetrain reversals in Porsche’s modern history. Just months after shuttering production of the fourth-generation 718 Boxster and Cayman—and confidently lining up bespoke electric replacements—Porsche is now preparing to reengineer that very EV platform to accept petrol power once again. In Stuttgart, the future just did a clean heel-and-toe downshift.

According to senior sources inside Porsche’s Weissach engineering center, the company is working to adapt the upcoming PPE Sport architecture—originally conceived as an EV-only platform for the next Boxster and Cayman—to accommodate a mid-mounted internal-combustion engine. The move comes as global EV demand cools and Porsche recalibrates a strategy that, until recently, pointed decisively toward an electric-only sports-car future.

This isn’t a minor tweak or a half-step hybrid hedge. It’s a full-on engineering U-turn, motivated by production efficiency, economies of scale, and—perhaps most importantly—customer appetite. Porsche has already acknowledged the shifting landscape with a costly £6.65 billion write-down tied to its EV ambitions. Now, the 718’s return to gasoline power marks the clearest signal yet that Zuffenhausen is listening closely to the market.

Two 718 Futures, One Platform

To understand what’s happening, it’s important to separate Porsche’s short-term stopgaps from its longer-term plan. The company previously confirmed it would continue building “top” versions of the outgoing 718—widely expected to be RS and GT4 RS variants—even as the electric Boxster and Cayman arrive in 2026. Those cars will effectively sit above the EVs in the lineup, keeping combustion alive for hardcore enthusiasts.

But the newly revealed petrol-powered 718s are something else entirely. These will be fifth-generation models, built on the same PPE Sport platform as their electric siblings, and expected to arrive toward the end of the decade. In other words, Porsche isn’t just extending the life of the current cars—it’s attempting to unify electric and combustion sports cars on a single next-generation architecture.

That’s an extraordinarily ambitious goal, and one that presents serious technical hurdles.

The EV Problem: Structure, Structure, Structure

The PPE Sport platform was never designed to host an engine. Like most modern EV architectures, it relies on a stressed, load-bearing battery pack integrated into a flat floor. That battery doesn’t just store energy—it provides a significant portion of the car’s structural rigidity and enables an ultra-low center of gravity.

Remove it, and the entire bodyshell loses strength.

Porsche engineers’ solution, as described to Autocar, involves developing a new structural floor section that bolts into the platform’s existing hard points, effectively restoring rigidity where the battery would have been. From there, a redesigned rear bulkhead and subframe would support the engine and transmission.

Even then, packaging remains a nightmare. The PPE Sport platform has no central tunnel, no provision for a fuel tank, no routing for fuel lines, and nowhere to run an exhaust system. Engineers suggest the rear of the car may need to be completely reworked—an acknowledgment that this platform is being pushed well beyond its original intent.

Still, Porsche insists that this effort is non-negotiable. For the petrol 718s to make sense, they must achieve dynamic parity with the EV versions. That’s a tall order when the electric cars benefit from that low-mounted battery mass, but insiders say anything less would undermine the brand’s sports-car credibility.

Euro 7 Changes the Math

For years, Porsche believed the naturally aspirated 4.0-liter flat-six was living on borrowed time. Early drafts of the EU’s Euro 7 emissions regulations threatened to bury engines like it under oversized particulate filters and complex after-treatment systems, making them impractical for low-volume sports cars.

That calculation has now changed.

The final Euro 7 rules are less severe than initially proposed, and the EU’s post-2035 exemption for e-fuels has reopened the business case for new petrol-powered performance cars. As one senior Porsche engineer put it bluntly, “The electric Boxster and Cayman risked becoming a niche. Euro 7 changed the arithmetic.”

In other words, the regulatory headwinds eased just enough for Porsche to reconsider what it does best.

Flat-Six Revival?

Exactly which engine will power the reborn petrol 718s hasn’t been finalized, but the leading candidate is familiar—and beloved. Internal plans presented by outgoing CEO Oliver Blume point toward a further evolution of the 4.0-liter naturally aspirated flat-six introduced to the 718 lineup in 2020.

In its most aggressive current form, as fitted to the GT4 RS, that engine makes up to 493 horsepower. Whether future versions match that output—or tune it differently to coexist with electric siblings—remains to be seen. But the message is clear: Porsche isn’t ready to let the flat-six go quietly.

What This Really Means

Beyond the technical intrigue, Porsche’s 718 reversal says something larger about the industry’s trajectory. Like Fiat resurrecting the 500 Hybrid or Mercedes-Benz rethinking its EV-first commercial vehicles, Porsche is acknowledging that the road to electrification isn’t a straight line.

For enthusiasts, it’s a rare bit of good news in an era of uncertainty. The Boxster and Cayman—long celebrated for their balance, tactility, and mechanical intimacy—may yet continue to offer the visceral experience that defined them, even as electric versions push performance in new directions.

If Porsche pulls this off, it won’t just have saved the 718’s soul. It will have created one of the most flexible—and philosophically complex—sports-car platforms the company has ever built.

Ford and SK On Call Time on a $11.4 Billion Battery Bet as the EV Tide Recedes

Back in 2021, Ford’s future looked decidedly electric. Flush with optimism and buoyed by generous federal incentives, the Blue Oval teamed up with South Korean battery heavyweight SK On for an $11.4 billion joint venture to build a network of EV battery plants across the United States. It was a bold, expensive, and very public declaration that Ford intended to be a serious player in the EV arms race.

Fast-forward to late 2025, and that confidence has given way to retrenchment. Ford and SK On are dissolving their battery partnership entirely, a high-profile breakup that says less about either company’s competence and more about how quickly the EV landscape has shifted under Detroit’s feet.

The split didn’t come out of nowhere. Two major forces have been working against EV momentum in the U.S. First was the rollback of the federal EV tax credit, a move that immediately cooled consumer demand and took some of the financial sting out of sticking with internal combustion. Second came the U.S. administration’s decision to revise fuel economy standards, a policy change that effectively tilts the playing field back toward gasoline-powered vehicles. Together, those moves reshaped the market in a way few automakers had modeled just a few years ago.

Under the terms of the breakup, the assets will be divided rather than abandoned. SK On will take over the already-established joint venture facility in Tennessee, known as the BlueOval plant, while Ford will assume control of the two adjacent factories in Kentucky. The arrangement keeps both companies in the battery business, just no longer under the same corporate roof.

Notably, it was SK On that formally dissolved the partnership, though the company has been careful to emphasize that it still plans to work with Ford around the Tennessee facility. From SK On’s perspective, the separation is about agility. Ending the joint venture, the company says, will improve productivity, increase operational flexibility, and allow it to accelerate its North American energy storage system business—an area that’s quietly becoming just as important as EVs themselves.

The fallout extends beyond factory gates. One of the most immediate consequences is a reassessment of a massive government loan approved near the end of the Biden administration. Originally structured as up to $9.6 billion in financing for the joint venture, the loan is now set to be reduced under the Trump administration’s oversight. How much smaller it will become hasn’t been finalized, but Bloomberg reports that the loan will be reworked to “reduce exposure to taxpayers and ensure its prompt repayment.”

Ford, for its part, is cooperating with the Energy Department and has signaled it’s willing to repay the loan faster than originally planned—a move that suggests the company is eager to clean up its balance sheet and put some distance between itself and a bet that no longer looks like a sure thing.

That urgency is understandable. Ford’s EV business has been bleeding red ink, losing $5.1 billion before interest and taxes in 2024, with even steeper losses expected this year. Domestic EV sales are sliding, and CEO Jim Farley has been unusually blunt about what lies ahead. He recently warned that, under current policies, EV sales in the U.S. could fall by as much as 50 percent.

From that vantage point, the breakup looks less like a failure and more like triage. “We believe the writing was on the wall this partnership was not going to work moving forward,” Wedbush Securities managing director Dan Ives told the Detroit Free Press. “Ford has to make some difficult moves and this was a smart strategic one to rip the band-aid off. The EV market is dramatically scaled down for Ford now and they have to adjust accordingly.”

That adjustment doesn’t mean Ford is abandoning electrification altogether. Instead, it signals a recalibration—one that prioritizes flexibility over massive, long-term capital commitments made under very different political and economic assumptions. The automaker still needs batteries, still needs EVs, and still needs a credible electrified lineup to compete globally. What it no longer seems willing to do is bet tens of billions on a single vision of how fast America would go electric.

For SK On, the breakup may actually be an opportunity. With full control of the Tennessee plant and freedom to pursue energy storage more aggressively, the company can diversify beyond passenger EVs and chase steadier demand from grid-scale projects and industrial customers.

In the end, the Ford–SK On split is less about blame and more about timing. The EV boom that automakers planned for in the early 2020s hasn’t vanished, but it has slowed, fractured, and become far more politically contingent. In that environment, even the biggest players are learning that sometimes the smartest move isn’t to double down—but to step back, reassess, and live to fight the next round.
