Third is the range you propose for this vehicle - even on internal fuel. 180 km off road? At what speed? How many kilometers per litre does your engine get?
Your Char-8E1 has a 906 hp engine running the tank at 60 kph, and yet has 350km range. The proposed tank has 48% less range whilst being 20% lighter than the Char-8E1. I fail to see the problem if the Char-8E1 was accepted.

I don't see why having a high hp/ton is implausible, especially when hp/ton is a value isolated from the rest of a design - factoring only weight and engine. If I placed a 150 hp engine with it's corresponding transmission in a 9mm steel box with roughly the same dimensions, I dare say it weight might be ~3 tons, then the PWR would be 50 hp/ton, is it somehow impossible to do this? I've heard of low PWR being bad, but I've never heard the same for high PWR.Quoted
Third, the power-to-weight ratio is about twice the period's mean (which is ~15 horsepower per ton). The Cromwell, which had one of the highest historic power-to-weight ratios of any 1940s tank, has a 22hp/ton ratio. 31 hp/ton is just a joke.
Your Char-8E1 produced en-masse has 25.2 hp/ton - is there some magical cutoff value? 25.2 is good but 30 is no good?
You keep saying this but I don't understand at all. The 100mm is the exact as as the one on the SU-100, the T44-100, etc. It is roughly equivalent to the 75mm/L70. Why it is not allowed?Quoted
First off, a 100mm gun is not justifiable at the present time in Wesworld. We mentioned this earlier in regards to your heavy tank, and we elected to make a one-time exception in light of the tank's size and a very limited production run. Yet you're now putting this gun on a much smaller medium tank meant for larger production numbers. So on this count, thumbs down.

The average guns require staggering amount of armor to protect:
10mm for small-arms fire
25mm for <20mm fire
40mm for 20mm fire
75mm for 37mm fire
140mm for 50mm fire
170mm for 75mm fire
210mm for 90mm fire
250mm for 75mm LONG barrel fire
280mm for 90mm LONG barrel fire
