McLaren is all set to add a new model to its supercar lineup, codenamed P34. It will replace the Artura by 2028. In fact, the Artura successor is already under development. An early test mule was recently spotted testing somewhere in Michigan, USA.
At first glance, the test vehicle looks like a slightly modified Artura. It has the same design, featuring sculpted side intakes and louvres on the front fenders, except for the rear fascia, which has a distinct look inspired by the M6GT.

The prototype vehicle has a flatish rear end with two central exhausts. It is also equipped with a fixed rear spoiler and a large diffuser.
The McLaren P34 will reportedly use a twin-turbo V6 hybrid, which makes around 810 hp and 800 lb-ft of torque. Prices for the new entry-level supercar are expected to start at around $313,000.
That being said, it is unclear if this is indeed the upcoming P34. McLaren might also be planning a more track-focused Artura LT before phasing out the model entirely.
