I think this proposal includes upping the engine allowance to 6-8 engines for a season, which doesn't make any sense if we've only got 3 next year. Personally, I'd love a twin turbo with a bigger MGU-H. That'd be crazy, and there's no sense removing technology from the engines. Make some absolute beasts out of, say, a 1.2L V4 or something. DRS actually came about because the FIA devised a working group to increase on track overtakes. This included Ross Brawn, I believe Paddy Lowe and another I can't remember. They were told they weren't allowed to add active aero elements for increased straight line speed, and so they concluded that refueling should be banned. This worked. Then Abu Dhabi 2010 happened and Alonso couldn't get past Petrov; DRS was introduced and the working group were confused as to why it was being introduced when they were told not to suggest such a thing.
