McLaren’s hybrid supercar story is already moving into its next chapter.
An early test mule has been seen running in Michigan, wearing familiar Artura proportions but carrying enough new hardware at the rear to raise a bigger question. Is this the first public glimpse of the P34, the planned Artura successor, or a final, harder-edged Artura LT before the model is replaced?
At a glance
- An early McLaren prototype has been spotted testing in Michigan and may preview the P34, the next entry-level hybrid supercar.
- The mule resembles the Artura up front but features a flatter rear treatment, central exhausts, a fixed wing and a large diffuser.
- The P34 is expected to replace the Artura by 2028, with suggested pricing around $313,000.
A familiar Artura profile with a sharper tail
At first glance, the test car doesn’t try to hide its Artura roots.
The low nose, sculpted side intakes and louvred front fenders all sit comfortably within the design language McLaren established for its compact hybrid supercar.
The rear is where the mule starts to separate itself.
Instead of the Artura’s current rear treatment, this car uses a flatter tail with two central exhaust outlets, a fixed rear spoiler and a large diffuser.
There’s also a clear nod to the McLaren M6GT in the way the rear fascia is visually simplified and pulled taut across the back of the car.
That detail matters because McLaren rarely adds this much rear-end aero hardware to a prototype without a performance intention behind it.
P34 and the Artura LT question
The name attached to the next-generation project is P34, and it’s expected to replace the Artura by 2028.
That timing makes an early development mule entirely plausible, particularly if McLaren is already evaluating packaging, cooling and aero changes on public roads.
There is another possibility.
The prototype could also point to a more track-focused Artura LT, a model that would follow McLaren’s long-running habit of giving key road cars a lighter, more aggressive final act.
The fixed wing, central exhaust layout and enlarged diffuser would all make sense on a sharper LT variant, especially if McLaren wants to send off the Artura before its successor arrives.
For now, the car sits in that intriguing gap between development mule and performance derivative.
Hybrid power remains central
The P34 is expected to continue with a twin-turbo V6 hybrid setup rather than move away from the formula introduced by the Artura.
Early figures point to around 810 hp and 800 lb-ft of torque, which would put the car comfortably above the current Artura and give McLaren’s entry point a much stronger position in the hybrid supercar field.
That output would also make sense strategically.
McLaren’s smallest series-production supercar now has to feel properly contemporary against a field where electrification is no longer a novelty but a core performance tool.
The expected starting price is around $313,000, though final pricing and specification could change before the car reaches showrooms.

Whether this prototype becomes the P34 or reveals an Artura LT in disguise, it shows McLaren refining its hybrid supercar formula rather than abandoning it.
The silhouette may still look familiar, but the hardware at the rear suggests Woking’s next move will be more than a routine update.
