There were two very interesting developments at McLaren during US Grand Prix practice. Although fitted to the 2016 car, both may be pointers towards developments for next year, with a new front wing appearing, as well as a comprehensive sensor set-up at the rear of the car.
McLaren has gone for a very different direction with its new front wing, with the way the wing meets the endplate being an almost retro-style 90-degree joint.
In recent years a trend started by Mercedes has led to the wing joining the endplate with an arched section, to create a strong vortex to push airflow around the front wheel.
