The largest Porsche model in history has just been given a big overhaul – two years before it was meant to go on sale. The full-sized K1 SUV was due to join the range above the long-standing Cayenne with a fully electric powertrain on a Porsche-developed SSP Sport platform, but plans have changed. You can currently buy a three-year old Porsche Cayenne from around £60,000 on the Auto Express Buy a Car service. What does this mean for the K1 SUV? The K1 will retain its place at the top of Porsche’s SUV range, positioned above the Cayenne, which will be available in two forms: the upcoming EV and the current ICE version with pure petrol and plug-in hybrid powertrain options.
