He impressed in the YDT this year and has performed remarkably well according to Marko.
"Whenever we put him in a car his efforts were remarkable," Marko said during an appearance on Red Bull's Servus TV channel.
And I read this from F1technical:

I also checked the times, and here is a link for those.

I'm not sure what the conditions where on the differing days of the test, but Kvyat was the slowest in terms of overall laptime between him, Sainz Jr and Da Costa.
Maybe he impressed them with his consistency......
But let me show my dissatisfaction with the decision in a different light, as it is unfair to judge Kvyat without him turning a wheel in anger yet.
Red Bull Media House have in fact recently(September 2013) signed a deal with Russian partners Russian extreme and IVI.ru to show Red Bull events.

We then also have the fact Russia represents an important market for Red Bull as a company.
14% total(drinks) market share as of August this year.
Problem is, Pepsi and Coca-Cola want some energy drink action too. Increased competition has resulted in (russian) market share going from near 100% in 2000, to 70%in 2008 to 50% today.
My point is, when a half decent Russian becomes available...with the possibility of actually paying for his drive, it is PR heaven for Red Bull. They are in F1 to sell cans of bovine taurine. Just as Mercedes, Ferrari et tal are here to sell
cars or maintain an image of prestige/legend.
If there is a memo from the Red Bull onlooker who watched Da Costa, and likewise Kvyat, I would love to have read it.
As I reckon it probably got crumpled under the weight of Red Bull's 2014 PR strategy.
Maybe I'm being over cynical...
Either way....Good luck to Kvyat(rolls off the tongue

)once again.
If I where Da Costa, my CV and agent would be doing the rounds as soon as the news broke.
