While McLaren has only provided preliminary details about its upcoming Speedtail previously, company CEO Mike Flewitt has now confirmed that the model will have more than 987 hp (1,000 PS).

As reported by Top Gear, Flewitt said the hyper-GT would use a familiar engine architecture, with the 710 hp (720 PS), 4.0 litre twin-turbo V8 in the 720S being the likely culprit.

As we’ve already been told that the Speedtail will sport a petrol-electric hybrid powertrain, the total system output with the electric motor(s) should be close what to Flewitt claims.

He adds that the hybrid system use will be different from what you find in the P1, which features an electric motor in the rear that provides 176 hp (179 PS), backing a 3.8 litre twin-turbo V8 with 727 hp (737 PS). Put together, the P1 offered 903 hp (916 PS), which is 84 hp less than the Speedtail.

The company isn’t chasing speed records with its new model, and says the top speed is around the 391 km/h mark. Instead, it is being described as “super comfortable, super to drive.”
