The Senna had been tipped to be the car McLaren would return to frontline GT racing with, with the development of a GTE (Grand Touring Endurance) version that would pave the way for McLaren to return to competing at Le Mans level.
The Senna has been created with the intention of being a focused tool optimised for track use, and it has now been seen in the two guises McLaren will offer it in: the standard, road-legal model and the track-only GTR version revealed today at the Geneva motor show.
It's understood the GTR was prioritised to appease customers who missed out on the initial batch of Sennas and also due to the greater financial returns the project would offer over developing a GTE race car to the current rules.
Flewitt said that McLaren is "not going to race" the Senna, either through the Automotive division he heads or the McLaren Racing F1 arm, which is open to other types of racing (as demonstrated by Fernando Alonso's Indy 500 attempt in 2017) but will not chase a World Endurance Championship (WEC) – and therefore Le Mans – entry with the Senna.
"This is it, the whole concept," said Flewitt on the two Sennas created to date. "It's the fastest road-legal track car, and it lets us take things like light weight and huge downforce to push boundaries. Doing a track-only version is a typical McLaren thing to do."
Flewitt said that the firm could use the Senna name in the future again, but that it was unlikely and there are currently no plans to do so.
