There are girls in the series known as "MFG Angels" hired for support and advertisement. They wear slightly revealing clothing, not too graphic.

The Angels-- race start girls, wear standard skimpy tops common to racing, but their bottoms are basically skin-tight white micro-panties, and are often the focus of the camera. Definitely "fan service" stuff and unrealistic to the genre.

A man is slapped in the first episode, leaving a red welt on his face. A rather mild scene.
