Seat Leon Cupra specs

why was the 1:20.5 time deleted?

Times are only deleted if the reference info isn't good enough.... I don't know about this lap but examples of not good enough would be "I did it" "Some magazine I saw" "Wikipedia" or "On a car blog/forum"..... the only acceptable refs are those that can be verified.

why was the 1:20.5 time deleted?

some of the modifications besides to reprogramming the tranny were:

Engine output up 5ps to 485ps Gas tank size expanded, 71 litres - 73.8 litres Slightly tweaked fuel economy 8.2 km/L to 8.5 km/L

and although I agree that most of the changes are irrelavant it still (officially) delivers 5 PS more than '08 version whereas this Seat is basically the same besides some minor changes to it's styling and ESP function.

thats wrong danielk the 09GT-R looks exactly like the 08model... the Cupra NOT... front and rear is different interior is different ...
what modifacion did the GT-R recive next to a reprogramming of the tranny?

this is a minor change, apparently XDS is a part of an ESP program, GT-R '09 has more changes compared to the previous model than this.

What's a XDS diff?

the 2009 Cupra is mainly only a little bit style change... but one important future makes it worth to add it as a own model. The 2009 Seat Leon Cupra comes now standart with XDS limited slip dif which should improve track perfromance...
