Lupo, 37 kw: Question about engine & gearbox?

Hello, I drove about 70-80 km today with my girlfriend’s 1-litre LUPO. I noticed the following things. Is it normal that the engine always sounds as turbine-like, almost like an electric motor? I mean, almost like a remote-controlled car? I also want to know if it’s normal to hear the gearbox. I mean now no snorting or hammering, but just such a quiet operating noise – actually no matter in which gears? So, I’m not yet I drove my other Lupo, which is why I can’t judge if this is so typical of Lupo. By the way, the corridors flood in 1st cream. I have more to fight with my Civic. Synthie
