Grosjean expects gains from exhaust upgrade

2013 Chinese Grand PrixPosted on | Author Keith Collantine

Romain Grosjean, Lotus, Sepang, 2013Romain Grosjean says he’s eager to get his hands on the exhaust upgrade that was run on his team mate’s car during the last race weekend.

“We’ve been making steps forward with performance and that’s always what you want,” said Grosjean ahead of the Chinese Grand Prix.

“The new front wing was beneficial and I’m looking forward to getting the latest exhaust configuration in China. Kimi [Raikkonen] used it in Sepang and it was definitely of benefit to the car.”

Technical director James Allison confirmed: “We’ll be upgrading Romain to the latest spec exhaust and related bodywork as run by Kimi in Malaysia.”

“We also have a few small tweaks to the front wing, rear wind endplates and sidepod vanes. One of the benefits gained from the new exhaust package is an increase in rear downforce through corners where the ratio of exhaust speed to car speed is high, which tend to be the lower speed corners.”

Grosjean said his start to the season has been “frustrating”. “I don?t think I?ve shown my full potential yet,” he added.

He finished sixth in Malaysia, ahead of Raikkonen, but believed he could have done better “if we?d had the car we wanted all weekend”.

“Starting further up the grid and making a better start would have helped too, but it?s always easy to say that,” he added. “During the race itself I spent a lot of time stuck behind Felipe [Massa] in the middle phase and I?m sure if I could have passed him earlier then I would have stayed ahead.”

“But by the end my tyres were finished so it was best just to let him through without compromising either of our races. There were a couple of times where maybe the backmarkers could have made things a little easier too.”
