Mercedes hoping to solve its MGU-H issues solved in Spain

Four wins from four races for Mercedes AMG Petronas’ Nico Rosberg is a perfect start from a results standpoint this season. However, as has been documented, internal MGU-H issues have been less than ideal for the team, which hopes to have its reliability concerns alleviated at this weekend’s Spanish Grand Prix.

Both of the team’s top two men – Head of Mercedes-Benz Motorsport Toto Wolff and Mercedes Executive Director, Technical, Paddy Lowe – noted the efforts to fix the reliability concerns going into Barcelona this weekend.

“The highest priority is to come back with our MGU-H problem solved, having had a repeat fault over the past two race weekends,” Lowe said in the team’s advance release. “The team has been working day and night to understand it and we’re targeting a clean weekend all round.”

“Assessing our season so far is an interesting task. On the one side, we are leading the Constructors’ Championships by a good margin and our drivers hold the top two positions in the Drivers’ standings. So, realistically speaking, it’s tough to ask for more,” Wolff noted.

“However, it has not been plain sailing and we have had problems that we are working hard to solve. We have rivals breathing down our necks who are relentless in their chase. The longer regulations remain stable, the harder it is to find extra performance.

“We are pushing the limits to ensure we remain competitive – but if you push the limits then at a certain stage you risk stepping over them. The whole team, on both the chassis and Power Unit side, is working flat out to extract every millisecond from our package without compromising reliability. This is a group of great engineers and I have no doubt that they are going to achieve that.”

Wolff addressed how improved Mercedes was on the back of its two most recent race defeats, at Hungary and Singapore last year.

“In Hungary and Singapore last year, we took a couple of big hits. But we came out of those races stronger and we continue to learn from our struggles,” he explained.

“We’re going to see some big upgrades from the different teams and Power Unit suppliers over the next few races, so now is the time we can truly assess the pecking order. Barcelona will be an interesting weekend from that perspective, so we must be prepared.”

Mercedes wrote an open letter to its fans last week, addressing potential conspiracy theories in the wake of Lewis Hamilton’s frustration following the Russian Grand Prix.
