Really? I have yet to hear of a case of a modern F1 driver greying out due to lateral G. It was quite common in the 80's. It was one of the factors involved in banning ground effects. Acceleration was better in the older turbocars. Braking is where the modern F1 car is light years ahead of any other.
Sorry I'm catching up late.
I came across an artcile in EVO recentlye that contained an interview of WRC Driver Kris Meeke.
Obviously Group B was mentionned and Meeke (who also happens to be an engineer) stated that current gen WRC cars were actually
several (5 or 6) seconds faster per kilometer.
Indeed, watching a WRC car surging out of a tight corner is quite something in itself.
Now, what's wonderful about those cars is that they can achieve those feats on half the power of Group B cars while being safe enough not to kill anybody .
On to F1.
The following video speaks volume about the speed of modern F1 cars even on slower tracks :
With that said, just look at how much more effort Senna seems to put on the wheel !
That's what sort of gets in the way of the "nowadays F1 cars are harder on the drivers". Sure the sheer amount of acceleration a modern F1 can generate is astounding ( 180 MPH to a dead stop in less than 3 secs, 5G's in some corners etc...), but nowadays they have power steering and sequential 'boxes.
I do believe that the amount of brutality that the older machines exhibit is simply unmatched. There's a reason why a well-trained journo can now get in the seat of an F1 and keep it on the track. Hammond, I'm sure, would have never made 2 laps around a track in an MP4/4 in qualy trim.
Now, today's drivers also have a lot more to do, intellectually speaking, than senna had. I don't want into the usual clichés, but just look at how much buttons those wheels have !
One of the reasons why I like Singapore's qualy onboard cams so much is that one can easily discern what the drivers are doing on their screens. Seeing Hamilton changing his car's breaking balance while going flat-out and passing slower cars like it's no big deal is simply mesmerizing.
One also has to take into account how fit the average driver is nowadays compared to the 80's. Senna and Prost were exceptions, just compare Mansell and Britney. See ?
Those guys put 10's of hours every week to train all while staying as light as possible (drivers' weight was less of an issue back then). Keeping up for 2 hours in Malaysia while being on diet of salads and orange juice only can't be that easy...
