LDM makes me laugh; it's unlikely that Mercedes will be swayed! Mercedes actually make cars with four cylinder engines and as people move towards economical cars rather than gas guzzling V8/10/12s, that's more likely to be their core business in the coming years. Ferrari is the only manufacturer that has a vested interest in V6/8/10/12 engines in Formula 1. If F1 is to become more road relevant then smaller engine with energy recovery systems is the way to go. Although a 1.6 L4 turbo does seem tiny, it doesn't mean it has to be puny in the power stakes, remember the old 1.5L turbo's those engines put out more than 1200hp. In real terms, the difference in the speed and acceleration of the current V8s and the new L4 turbos will be minimal! If F1 does not suit Ferrari/FIAT's business model, then like their fellow manufacturers Honda, BMW, Toyota and Honda it's time to make for the exit, that only makes good business sense, that is talking from a business sense only, not from a sporting sense!
Happy new year myown, hope you had a good one.
As to your post, hmmmmm. Where to begin.
Mercedes - we will see I guess.
v6/8/10/12 no more must equal gas guzzling than 1.5l turbos must equal low power - both are ridiculous statements. F1 is not and never should be about the mediocrity of the average mass-selling production cars. If you are really concerned about energy efficiency and total resource usage then think carefully before you throw out the v6/etc in favour of small battery/turbo/hybrid engines.
F1 suits Ferrari/FIAT's business model fine. And don't make the totally ridiculous implication that cars for the masses, including turbos aren't part of their groups total business. In fact, FIAT arguably are bringing the most innovative and best turbo technology to market this year with their Multiair engines.
