Why is Lewis Hamilton under performing this season?

May be...

The McLaren is absolutely crap this season and is not at all competitive.

I predict Hamilton will only finish 11th in the championship unfortunately.

It's THE CAR... something you would LEARN if you actually LISTENED TO THE ANNOUNCERS instead of playing with your XBOX or chatting on your computer because you are one of those morons who have to do 10 things at once... ALL OF THEM DONE BADLY.

With the new regulation brought in for this year, the design of the cars have changed vastly from last year.
And Mclaren just didn't get it right this year. Same with Ferrari, neck and neck with Mclaren last year but just dropped off this year, again they just haven't designed their cars well.
Where as Red Bull and the new Brawn GP have made smart decisions in the design of their cars and it has shown in this years championship.

Yes Mclaren and Brawn are using Mercedes engines but its also a combination of all the components of a car that give it its overall performance. Force India also have Mercedes engines but they have really only improved their race performance by about 3 or 4 positions on average compared to last year.

After Sliverstone he is 11th in the championship, 10 places lower then he would like, but I think thats roughly where he will finish the year. Somewhere around their. The performance of the MP4-24 just doesn't stack up againest the new leaders of the field.

Dude his car is 9 tenths of in qualifiying, this may not sound like much but in F1 it is a lifetime, mainly it is the straightline speed and cornering which is bad on the car. The balance is good though, Mclaren put all of the effort into last season to make Lewis win.

I think he will get into the top 15.

i think it was Eddie Jordan who said a few races ago that Mclaren seem to always put their effort into a winning car, and then they havn't worked on a new car for the next season, so they sort of rush it to get a new car, that doesn't work really.

Last season when he won the F1 World Championship, he displayed passion, desire, and was a fighter.

what is with the sudden change in his performance?

What position do you think he will finish at the end of the season?what graphics card to buy
