The equivalent Euro NCAP class is called "roadster sport".
[1][2] S-segment cars have a sporting appearance and are usually designed to have superior handling and/or straight-line acceleration compared to other segments.
The most common body styles for S-segment cars are coupé and convertible.
Rear passenger accommodation is not a priority for S-segment cars, therefore many models are either two-seat cars or have a 2+2 layout with relatively cramped rear seating.
In 2014, the five highest selling coupé models were the BMW 4 Series, Opel Astra GTC, BMW 2 Series, Renault Mégane Coupé and Mercedes-Benz C-Class (W204).
