World engine gathering steam

One thing I don't like is the idea of 1600s, they sound awfully fragile to me, especially if they want 450hp coming out of one!

Whilst this is to do with both rallying and touring cars (and it could be adopted elsewhere), I decided to post it here because Autosport filed it under WRC

Can someone explain this article to me? please ))

1)Why do they need same power from 2.0 and 1.6 turbo units ? Manufacters will be allowed to choose engine concept or ? And about power, 300 hp now, 250 hp from 1.5 , 450 hp... Do they really now how much power they need. Isnt 450 hp too dangerous like group B was earlier ?
2) About costs. Why do they say 2.0 450 hp engines are cheaper, i thought turbo-engine are easier to tune. Or its about reliability ?

It sounds like what they want to do is vary the levels of power for different concepts. The initial World Engine plan was a plan to have a similar engine system for F1, WRC, Super Palmer Audi and certain other series. It looks like they have decided to split this in two and go for a 1600cc and a 2000cc unit.

450hp would be too much for rallying, but this plan is for more than rallying (of course, it would be acceptable for touring cars). The main issue is that 450hp is too much for 1600cc, end of.

2) About costs. Why do they say 2.0 450 hp engines are cheaper, i thought turbo-engine are easier to tune. Or its about reliability ?

I'd think it would be reliability (then again, if they want reliability why not junk the 1600cc and just go for two litre turbos, use a similar set of rules and different tuning limits for everything from Formula 3 to the WRC, the BTCC is going down a 2.0T route with 300hp), and the need to only develop one engine per marque.

The idea is that manufacturers can churn out 1600cc and 2000cc engine blocks and add the appropriate valvegear/forced induction systems to achieve multiple levels of horsepower.

The idea of different configurations looks like a good one, Subaru (and possibly Porsche) will want to run flat engines, and I suspect that the big three American companies plus Honda, Toyota and Merc will want V6s.

I strongly believe that there should be only one limit capacity and weight of the vehicle, also there should only be a limited number of engine changes or rebuilds allowed. It is the job of the manufacturer to make it reliable and fuel efficient (so it can do one F1 race on one tank!).

In the current downsizing trend I think this should be 1400 turbo's and 2000 turbo for the unlimited categories...

This would bring back some of the fun that has been missing for a while in motorsport. It would also contribute to new developments and bring back the hardcore streetrace mentality. Today all classes are so restrictive they result in about the same speed...

Bring back the group B and C spirit (in a more eco friendly way with small engines)!
