A Saturday second placing and a Sunday sixth placing meant Brendon Hartley maintained his consistent form in the 3.5 World Series Renault Championship at Brno in Czechoslovakia at the weekend
The New Zealander has been a top six contender in all four rounds of the 2010 International series and, but for a technical problem while challenging for the lead at Spa, would have finished in the first six in all seven races to date.
The 20-year-old Red Bull driver qualified third for the Saturday race at Brno and finished just 1.9 sec behind race winner Esteban Guerrieri. In the Sunday race with a mandatory pit stop, Hartley qualified sixth and was up to third on lap 10.
However, he dropped to sixth after the round of pit stops, behind his Tech 1 team mate Daniel Ricciardo.
Esteban Guerrieri completed a double victory at Brno. In a repeat of Saturday's race, the Argentinean made a better start than pole-sitting team-mate Filip Salaquarda, and from the inside of the front row powered into the lead at the first turn.
Guerrieri appeared comfortable in front until increasing understeer allowed French rookie Nathanael Berthon to reel in the leader. From his second row starting position, Berthon's strong race pace allowed him to get ahead of Salaquarda during the pitstop sequence.
Berthon applied heavy pressure on Guerrieri for six laps but was not able to stage a serious passing attempt. Berthon elected to drop back on the penultimate lap to finish 1.1s down at the flag.
Having survived an attack from third starter Stefano Coletti into the first corner, which resulted in the Monegasque spinning off on the dusty outside line, Salaquarda held off a tight squabble involving Walter Grubmuller and Daniel Ricciardo for the final place on podium.
Hartley followed his Tech 1 racing team-mate Ricciardo home to complete the top-six. Ricciardo's result was not enough to demote Mikhail Aleshin as the mid-season points' leader therefore the Russian claimed the prize demonstration run in Renault's roadshow Formula 1 car at Magny-Cours on June 19-10.
Sten Pentus appeared to be an innocent party when he was knocked into a spin on the opening lap at Turn 3.
