JEREZ DE LA FRONTERA, Spain, Jan 15, 2008 (AFP) - Spain´s two-time world champion Fernando Alonso was the fastest driver here on Tuesday on the second day of Formula one testing that marked his return to Renault after a tempestuous season at McLaren.

Alonso, who won back-to-back world championships with Renault in 2005 and 2006 and came close last year with McLaren, went around in one minute 19.503 seconds to finish with the fastest lap time at the Circuito de Jerez.

"I don´t have concrete goals for this competition. Personally it´s an opportunity to become acclimatized to driving a single-seat car without electronic aids," he said.

Renault has adapted last season´s car for testing by removing driver aids which have been banned under new Formula One rules.

"It´s the first time that I have driven without traction control but by the end of my runs I started to go faster and take more risks with the car. The first day of testing was definitely very positive," he added.

Alonso´s season at McLaren was marked by an intense rivalry with his team-mate Lewis Hamilton. He signed a two-year deal with Renault last year.
