1. Current engine formula with a slightly modified fuel flow limit or even fuel capicity, but vice versa max. rpm 14.000 for cost saving reasons. That´s all. To change the current engine formula as little as possible is the cheapest way. After that, further main changes up to 2020+ should be prevented in advance to try to lure new manufacturers into F1 and give them a secure investment.
2. legalisation of water injection with water/alcool (methanol) emulsion (kinda MW 50 resp. HFS6 system). Reasons could be
- fuel saving effect because of a leaner mixture
- engine is better protected e.g. against thermic problems which correlates with the tighter restriction of engine numbers
- the emissions can be further reduced (NOx) which correlates with the "eco" badge of the PU
- intercoolers could be spared/optimized packages
- higher boost pressure, earlier ignition timing ->more power which correlates with the ominous "1000 hp" engines some require
plus
- broader tyres, bigger cars width
WI is outdated some may say; wasn´t also direct fuel injection??
3. the Honda idea of additional electric generators at the wheels sounds interesting
4. additionally, the architecture of the sport has to be revamped as there is no sense in letting in the McKinsey squad analysze which mechanic, tool, coffee machine or toilet paper could be spared in F1 when in contrary money is driven out of F1 constantly. Equalize the distribution key, so many restrictions due to "money saving" will become unnecessary (jokes like no spare front wing for RBR at Jerez test, no spare cars so the billion dollar test is finished after some laps etc.). Do it, despite of red herrings like the "sound discussion".
