When I started reading this I thought 'wow I’ve never heard of this' so I immediately went to youtube and watched a 2 hour documentary about solar car racing, which was much more interesting than this [I recommend watching that. If you plan on reading this then watch it after] it had heroes/villains & action & many plot-twists [yeah it was a good documentary, guesstimation of 8/10]. A large part of solar racing seems to be the in-depth work in regards to the engineering that the team goes through in making/designing the car but this manga seemed to skip over a lot of that. Thecharacters were fine and motivations & backstories were well done for the two main characters (7/10). I would have liked if they had given more details about solar cars and racing in general, I also didn’t like that they had a completely inexperienced driver lead them to victory because it didn’t really make sense [one of the other drivers was an f3 driver] he did ride his bicycle but they didn’t really show him learning how to race [at least the co-driver practiced racing Suzuka circuit in a game, but mc didn't].
Overall, 6/10
