It's not every day you see a hypercar listed among the recall notices.
The term "race car for the road" gets thrown around a lot, but if there was ever a car that deserved it, surely it's the McLaren Senna. Making a road car that close to a racer, though, has left it rather high-strung. Higher-strung, it seems, than even McLaren expected.
The National Highway Traffic Safety Administration has announced the recall of 129 examples of the Senna to have a crucial component in its engine bay replaced before those high-powered engines fail. Given that McLaren committed to making only 500 examples for the entire world, we get the distinct feeling those 129 units constitute every last one of them in America.
The problem, according to the recall notice, comes down to the engine harness, which "may contact a metal link pipe heat shield, chafing the harness over time, potentially damaging the wires" and causing the engine to stall.
It's the sort of problem that a pit crew might resolve at the track, but in the hands of private owners, apparently warrants a recall. That will require replacing the engine engine harness, a timeframe for which the manufacturer has yet to finalize, but will surely undertake in short order. Because the owners of these (nearly) million-dollar hypercars probably wouldn't appreciate having their engines stall, or leaving them in garage until McLaren gets around to fixing them.
Named for one of its most famous racing drivers, the Senna was revealed at the end of 2017 as the third model in McLaren's Ultimate Series – following the F1 and P1, and preceding the new Speedtail and the as-yet unnamed speedster recently announced.
The Senna packs the same 4.0-liter twin-turbo V8 as the 720S, tuned to produce 789 horsepower and 590 lb-ft of torque, and mounted in the middle of an altogether more hardcore carbon-fiber chassis. It's said to be capable of hitting 62 miles per hour from a standstill in just 2.8 seconds and topping out at a redline-restricted 211 mph.
