Hey CR
The featherweight aspect of the Honda Insight was key in selecting what vehicle to use for my engine experiments. Accelerating the car up to speed obviously works better with less weight, but also the light weight helps with going up grades in the road.
The "hillbilly proving grounds" I use in my videos has a wide range of road conditions, but the most difficult challenge is going up hills. Now, during the summer I kept the car at a friends house that was located near the Hillbilly proving grounds and that worked out great for filming. Due to the onset of winter I brought the car back to my house were the road conditions are not as favorable.... lots of hills and lots of traffic. Its a little bit scary to drive such an underpowered car in my part of town.
So yeah, lightweight and aerodynamics goes a long way with such a small engine, but honestly I truly believe the car is too slow to be safe, unless it is driven in a rural area.
Now for the purposes of entertainment the car is constantly evolving and getting more and more faster. I believe the larger 420cc engine will help make the car more driveable in an urban environment. Now keep in mind that the channel caters to small engine enthusiast especially the gokart and mini bike audience... so we will also continue to experiment with the smaller 212cc engine.... even though it is impracticable to use for the purpose of actual transportation.
I think if the viewers keep an open mind they may find value is some of the future topics we will cover. Anyway, its a fun project and a great learning experience.
