No, but LDM said himself, they are not going to put a 4 cylinder engine in a Ferrari, but they do commonly use V8 engines, hence why F1 is currently relevant to their road cars!
As I said, none of the F1 engines are used in road cars. Ferrari's made turbo F1 engines in the past. FIAT are going into 4 pot turbos in a big way and this technology may well become the basic turbo for the masses for Chrysler as well. So, it is genuinely silly to say it's not part of Ferrari/FIAT's business. As I said before, this is about mediocrity/green-ness taking over F1 (or at least trying to).
Why can't F1 be about about superlatives and leading edge with four cylinder engines?
Well it could, but you tell me what's superlative about a 4 pot turbo limited to 12K revs and producing just over 600HP - even you must see what a joke that is?
Ferrari is the only one that don't make family vehicles that tend to be L4s as they are the most cost effective and economical!
There, you've said it yourself, F1 to be driven by 4 pot economical family vehicles.

How's that for an oxymoron "F1-family vehicle" I reckon that's better than "smart bomb".
Lets look a little into the future F1 driven by "economical family vehicle manufacturers"
Lewis straps in the kids as he indicates before taking the MP4-1/29 out for Q3 session.
Fernando winding the window up on the F2015 as he turns the radio on and showcases the velour seat covers before he opens the glove-box to get his calculator out so show how much per month the repayments will be on next years model.
Sebastian stuns both of the crowd, and all three of those watching on TV, with an awesome lap that is completed using only one AAA battery and less than a micron of rubber.
