Porsche's 'K1' SUV Spied Testing Ahead of 2027 Arrival

• Porsche is developing a new flagship SUV—codenamed "K1"—that will be bigger than the mid-size Cayenne.

• The K1 has a boxier roofline and will likely have room for seven passengers.

• A new 900-volt electrical architecture will help reduce charging times, and the K1 is expected to have an air suspension and rear-axle steering.

Nearly two years ago, Porsche confirmed plans for a new flagship SUV that will sit above the Cayenne in the automaker's lineup and ride on a new electric vehicle architecture. Now our spy photographer has captured photos of an early prototype testing near Porsche's development facilities in Germany, providing a better sense of just how big this new crossover—codenamed "K1"—will be when it arrives for the 2027 model year.

In the photos, the K1 looks considerably longer and chunkier than the Cayenne. The more squared-off roofline is accentuated by the side window profile, which kicks upwards at the rear instead of swooping downwards, although this section may be a facade covering the true daylight opening. While the front and rear bumpers are heavily masked, the headlights take on a very similar shape to those on the new 2024 Macan EV, and the thin taillights form part of a black trim piece stretching the width of the liftgate.
