What is the name of this innovative French coupe that features a brake button instead of a brake pedal?

While equipped with many other unique features, the 1970 Citroën SM has a unique button the driver has to press to brake instead of the traditional brake pedal. You have seen this brake button in action if you've ever watched 'The Longest Yard' with Burt Reynolds.
