Fans want louder engines, and so does F1's sporting manager, but while Brawn is obviously attentive to the fan community's desires, bringing back non-aspirated high-revving engines isn't the plan.
Is a 'non-aspirated' engine the same as a 'naturally-aspirated' engine?
I was hoping to see more in the article abut the 'tactical' use of hybrid technology. For example, at first I wasn't a fan of Indy Car's 'Push to Pass' feature, but I do see how using it becomes a strategy towards the end of the race.
It might be interesting to see DRS activation in F1 be at the driver's control, limited to 10 or 20 uses depending on the track, and see how that plays out as a strategy.
The push to pass systems are in the mapping of the engine to provide addition boost, fuel, timing, rpm, etc. I would think to keep the Mfg's happy F1 would have a simply hybrid system to charge a battery bank for the extra energy. F1 could do away with DRS zones and just let drivers control the rear wing and additional power on their own. The limiting factors would be battery size and level of recharging available. This would get the drivers in control and allow passing anywhere on the track.
