Likely McLaren 750LT prototype tests at Nurburgring

‘Long Tail’ version of 720S is expected to come next year, as indicated previously by McLaren boss

McLaren is understood to be readying a faster, lighter ‘Long Tail’ version of the 720S for launch next year – and a new prototype caught testing appears to confirm that.

Although this test mule looks at first to be a standard 720S with some modifications, tell-tale cues including ‘gurney’ flaps and a substantially larger front splitter. Although the traditional Long Tail extended rear end – found on models such as the current 600LT – doesn’t feature in this early mule, the extended spoiler plastered in tape suggests engineers are testing for such bodywork modifications prior to completing them.

McLaren is yet to confirm whether or not it’ll use the 750LT name for the Long Tail model, but earlier this year CEO Mike Flewitt told Autocar that the power gain from S to LT will be “at least” as much as that which turned the 570S into the 600LT. As such, a 740bhp (750PS) figure is expected.

However, he also stated that engineers have been struggling to shed the 100kg now expected of LT models “because we made the 720S as light as we could in the first place”. It’s expected McLaren will still be capable of removing a meaningful amount of weight, however. 

The Woking firm is also battling to find an aesthetically pleasing way to incorporate the top-exit exhausts seen on the 600LT into the 720S’s body – something this prototype doesn’t have. That suggests a decision is yet to be made. 

A production limit has yet to be decided for the model, which could arrive in the middle of next year. “Part of me wants to keep it open as Porsche does with its GT models,” said Flewitt, “but we maight limit it to something like 750 of each [coupé and Spider].”
