Having being involved in Motorsport in a previous life, you hear lots of stories, most are true,but you keep the peice unless you are 110% sure,due to the amount of money involved, as for the Ferrari suchmacer era, and Bennaton I'm saying nothing.. Before you build a car, you read and re-read the rules and technical regulations, then build it.. But this makes good reading,

This is what Mercedes have done in recent years, and done it better than everyone else.
Ferarri dont. If they are winning they are cheating. During the Schumacher era it was ridiculous. Everyone knew they had traction control during the years it was banned. And thats just one example.
They were threatening to pull out of F1 due to no success for a long time, so it is thought that Bernie and Max turned a blind eye to the blatant cheating.
When Ron Dennis stepped out of line once too often, by grumbling about it they almost destroyed him and his team.
In the last two or three years they have been muttering about pulling out of F1 again, and lo and behold their car is suddenly a missile again.
To their credit the FIA put a stop to the cheating late last year but signed an agreement with Ferrari to keep details of the cheating secret !
The other teams are rightly very pissed off about this and are talking to lawyers about forcing the FIA to publicise what went on behind closed doors.
This season Ferrari are mid field runners, which is exactly where they should be. They havent been a genuine top flight team since the mid 70,s.
What will happen in the future, with the three really important jobs in the sport filled by ex Ferrari men, who have been up to their necks in the past shenanigans, only time will tell.
