Sorry, where did he specify the powertrain was restricted?
I took it as implied since he specified 50L of fuel. If its not restricted to a combustion engine, why bother restricting the fuel?
With this formula, KERS would obviously be a must, as it would improve the efficiency and add power without increasing the fuel consumption. So it would obviously still make sense to restrict the fuel.
I also think this in many aspects is a great idea, but I see one issue which I suspect would be a problem: The most significant area of performance for racing car is by far the aerodynamics. So with no restrictions on the aerodynamics, I doubt there would be much innovation done on the engine/efficiency, as long as the greatest potential of improvement lies in the aerodynamics. In the very beginning the teams would probably optimize some kind of known technology and then mainly focus on aerodynamics. If I am correctly informed, the aerodynamic improvements made to formula 1 cars over one season is worth at least a couple of seconds in lap time, even with all the restrictions today. In order to gain a similar amount of lap time by increasing the efficiency and thereby the average engine power, the difference would have to be very large.
If one team could get an advantage of an average of 50 hp more than the opposition, that would be an incredible achievement in terms of fuel efficiency. But it wouldn't be worth more than a few tenths in lap time (given power outputs similar to today's car). Of course, if the fuel was limited to only 50 liters, the average power over 300 km would probably be much lower than today, even with the improved efficiency. In that context the benefit of 50 hp ekstra would mean more, but it would also be more difficult achieve.
So with such a formula I would think it necessary to restrict the aerodynamics in order to make it worth while to work on the fuel efficiency. On second thought, it may be that this formula wouldn't allow much aerodynamic downforce, because of the need to reduce drag and in that case it wouldn't be necessary with restrictions, as making a car close to the lowest drag possible is quite simple and won't be worth that much in lap time.
