What Is the Porsche “K1”? The Flagship SUV Above the Cayenne

Porsche is developing a new SUV called the “K1.” While the name might be unfamiliar, this model is a 7-seater flagship SUV positioned above the Cayenne, designed to compete head-to-head with the BMW X7 and Mercedes GLS. It will be the largest and most expensive SUV in Porsche’s lineup.

Originally, the K1 was being developed as a dedicated EV.

Built on Volkswagen Group’s next-generation EV platform called the “SSP (Scalable Systems Platform),” it was set to symbolize Porsche’s electric vehicle strategy. However, in February 2026, an Autocar report revealed a major shift in plans. The K1 will no longer be EV-only but will feature a 4.0-liter V8 twin-turbo and a 3.0-liter V6, sharing its platform with the Audi Q9.

Why the EV Plan Was Scrapped: Three Key Miscalculations

This pivot stems from three harsh realities Porsche is facing.

First, significant delays in SSP’s software development. Second, disappointing Taycan sales have led to EV demand falling short of initial expectations. Third, soaring development costs. According to Bloomberg, new CEO Michael Leiters is even considering halting EV development for the 718 model, signaling that Porsche’s entire EV strategy is under pressure.

As a result, the K1 will adopt a shared platform with the Audi Q9 to reduce costs and aims for a gasoline and plug-in hybrid launch around 2028. Porsche says an EV version will come “eventually,” but no timeline has been given. Power outputs are expected to range from 348 to 730 horsepower, with the V8 model promising a powerful SUV experience. However, the decision to share a platform with the Audi Q9 may leave Porsche purists conflicted, given Porsche’s history of valuing its unique engineering—especially since the Cayenne broke away from the Q7 to develop its own chassis. While this is a pragmatic, cost-driven choice, it may leave some enthusiasts uneasy.

A Taycan Owner’s Perspective: Is the V8 Really the Right Choice?

Here, I share my personal view.

Honestly, I have doubts about this direction. From my daily experience with the Taycan Turbo GT, I’ve come to appreciate how superior EVs are for everyday SUVs. The instant full torque the moment you press the accelerator, the seamless acceleration without gear shifts, and the convenience of charging at home to wake up to a full battery—these benefits become clearer the more you drive an EV. Once accustomed, stopping at gas stations feels like a hassle.

The 4.0-liter V8 twin-turbo certainly sounds impressive on paper.

But most buyers of SUVs in this class use them for daily errands—commuting, shopping, and ferrying kids around. At low city speeds, a V8’s capabilities are largely wasted. Fuel economy suffers, turbo lag can be noticeable when starting from a stoplight, and no matter how advanced the multi-speed automatic transmission is, it can’t match the directness of an electric motor. With the Taycan, your right foot’s intent translates immediately into acceleration—a responsiveness that shines in busy urban settings. Those who can afford a K1 likely have the means to install EV charging at home. Plug in overnight, and you’re fully charged by morning—no need to hunt for gas stations or deal with messy refueling. For everyday driving, EVs are simply more comfortable and enjoyable in my opinion.

Spreading the Joy of Everyday EV Porsche Ownership

That said, I’m not here to say Porsche’s return to V8s is “wrong.”

For those who haven’t experienced EVs daily, the roar of a V8 and the pride of ownership remain powerful draws. The engine’s presence, exhaust notes, and rising revs appeal to the senses and are still at the heart of what many consider driving fun. If the market demands it, Porsche’s response is a sound business decision.

What I hope for, though, is that more people get to experience the everyday benefits of an EV Porsche. At home, my wife’s Taycan 4S Cross Turismo plays exactly that role, having covered over 35,000 km without any inconvenience—whether for shopping or long trips. We’ve even joked in the Taycan, “Even with the Panamera Turbo, I don’t think I could go back to a V8 engine.” Once you get used to the smooth, powerful EV drive, the thrill of engine start-up and exhaust notes can feel less compelling. This isn’t a loss but an evolution in how we relate to cars.

The slight sadness I feel about Porsche’s EV strategy retreat comes from knowing just how good EV Porsches are. I hope the K1 EV version arrives sooner rather than later. When it does, if more owners consider switching from V8s to EVs, that will be a happy future—for Porsche and its enthusiasts alike.
