These "hybrid" engines are a puzzle box. Still they had simulations on the dyno and in the chassis that should have revealed issues. Only a real track day testing showed them how serious the shortcomings of the engine are.
Honda's Turbo engines in the Indy Car series have been very reliable, but they are missing half of the technology.
There is a lot speculation that Honda is using the engines to get their company back into a position to field a full within a a couple of year.
It's been discussed that curtailing track testing has not reduced cost, the original premise for the 'rule.'
Simulations and more electronics have increased costs, but still can't make up for the real thing.
It's kind of ridiculous that the highest performance category in Motor racing cannot test more, and has to reduce / monitor fuel flow to the present extent.
I miss those pedal to the metal chases of old.
One of the first races my dad took me to as a kid was on the old Nuerburgring, with Mario Andretti chasing the leaders through 172 corners per lap.
From one hillside you could see Bruennchen, and then again get a top view of the cars go through the steep banking of carousel. All the way pushed down on what little suspension they had and sparks flying, very cool.
Smaller teams without state of the art simulators, wind tunnel's / rolling road etc. are handicapped from the get go.
In the post race interviews, Sauber's Felipe Nasr mentioned that the team has no driver simulator.
My other pet peeve is the weight of cars with driver. The drivers should be allowed to have a few more pound and not being handicapped for being taller and perhaps heavier. Its been done before with a little ballast.
We know they are athletes, but the tall ones look a bit haggard to me.
Just my 10 Pfennig.
