You've touched on a bit of a specialist subject of mine here; microcars, so here goes with what I think I know:
A: Share2Drive SVEN from, Aachen, Germany (as currently being exhibited at the 2019 Geneva Salon)
Yes of course. When I posted the puzzled in February I didn't know this car was going to be shown in Geneva a few days later!
SVEN stands for Shared Vehicle Electric Native. First point
C. ECOmove QBEAK from Denmark
No, Oguerrerob got this one.
G: Vetrya, Italy
Since I'm going to give you a bunch of points, I will make you work a bit to get them.
Vetrya is the electronics company that presented this car, but what is the model name of the car itself? Locked for you.
H: Kamisato Town Ultra small mobility, Japan
That's what I thought too when I first found this image, but it turns out that this car has another origin and another name. Since you found the Kamisato link, I will lock this for you as well.
J: Project PRCEK Urban Racer, CZ,
Yes. Developed and built by Martin Hreben & Jiri Uiberlay, presented in 2013. Second point.
K: Daechang Daningo, South Korea
Yes. The name is actually Danigo. This Twizy competitor was presented in 2017 and is said to have a 100 km autonomy. Third point.
L: PICAV (Personal Intelligent City Accessible Vehicle), from Australia
Yes, it's the PICAV. It surprises me that you assign it Australian nationality, because this is a European Union project, in which many entities of different countries participated, but all of them were European. The project was led by the University of Genoa, so had this car as Italian. Anyway, I consider this one solved and it's your fourth point.
M: Belo, based on an OSTAV platform, Greece
Yes. This is a virtual design proposal by Roe Design Studio, located in Tríkala, which is also accesible for wheelchair users. Fifth point.
N: Mobilis Li, Brazil
Yes. Mobilis is a start-up created by the engineers Thiago Hoeltgebaum, Mahatma Marostica and Paulo Zanetti, based in Palhoça, near Florianopolis. The Li, presented in 2017, is supposed to go on sale this year, in three possible configurations: Trail, Comfort and Work. Sixth point.
P: Thalia, Mexico
Thalia is the base model name of this car, but I'm going to ask you for the name of the company behind it, and the name of this specific version (again, there are three). Locked too.
So there you go! You get six points from this post, and there are another three waiting.
