it makes no sense like in the china grand prix lewis hamilton does a fast lap at 1:36 then Micheal does a fast lap in 1:32
4 years ago. how can he be so dominant by 4 seconds a laps its like impossible

is it the car he was using?

is there change of track?

is the condition so much different?

or some change of rules?

or is he just that good

( btw l only started watching f1 this year so l don;t know much)

.

Rule changes

.

The rules and regulations are always changing in F1 so there is no real way to compare laptimes from four years ago to todays laptimes. Have you looked at other drivers laptimes from four years ago? They are all probably within a few tenths or hundredths of a second of Schumi is time because four years ago they probably used different tyre compounds, areo and engine regulations were different and some other stuff as well.

Tyres, aerodynamic and engine developments driver gaining new skills?!!

In general F1 aerodynamicists never stand still but the FIA now see it in their infinite wisdom to slow the cars down. As to make it 'safer' for us .Hmm,
Grrrrrr. . . .. .

actually the F2004 or the 2004 ferrari was almost 2sec quicker than the 2008 cars...

if u put an 2004 minardi against an 2008 mclaren(mp423) both would have an close race!!

The things have changed since then..and cras have been made deliberately slower.the engines were V10 is in 2004 & now they r V8 (2.4l)..an the aerodynamics have also changed.!!

Short answer. All of those things combined + the fact that they were then running with much more powerful engines.
Welcome to the world of F1. Enjoy every bit of it with your buddies over some snacks or drinks, its really something. Do not known eveything myself, but got hooked 2 years ago to the sport to some friends.

Do not forget the condition of the track, wind, etc. That is why sometimes you see different laptimes for the Friday practice sessions.

Besides, the engines were more powerful back then, half of the lap records were held by Montoya, Schumacher and Barrichello and most of them were set in 2004.

Let me answer all ur questions:
1- The car he is using? yes the Ferrari f2004 is the fastest car in F1 history.
2- The track has slightly changed but not the course just heights.
3- The conditions r never the same but they were close & definitely they can not cause a 4 seconds margin.
4- Yes the rules were changed so the teams stuck with the V8 2.4L engines instead of the V10 3.0L & other regulations so the cars r much slower now to keep it safe.
5- He was that good & so was Kimi Raikkonen whose fastest lap at Spa in 2004 was 1:45.108 but now he became old so his fastest lap at Spa this year was 1:47.930.
BTW: l hope u continue watching f1 after u know that the rules in 2011 will force the teams to use V1 0.1L engines generating top speeds around 100 km.hr
