Red Bull team boss Christian Horner says his team won't be bringing a raft of updates to Spain for its RB15, but rather a series of "subtle" evolutions.

Thanks to Max Verstappen, Red Bull Racing has concluded all four races so far this season in the points, with the Dutchman scoring a podium in Melbourne before tacking on three consecutive fourth-place finishes in Bahrain, Shanghai and Baku.

The Milton Keynes-based outfit is still attempting to bridge the gap with its Mercedes and Ferrari rivals and while rear end downforce issues weighed on the RB15's performance in the opening two races, set-up changes have improved the car overall.

However, contrary to last year when Red Bull implemented a big upgrade package in Barcelona, next week's race will only see the addition of a few updates destined to help the RB15's balance and diminish tyre degradation.

"It's fairly subtle and it's just evolution," said Horner. "It will be the usual front and rear wing upgrades. It's evolution rather than revolution."

"I think we've closed the gap since the beginning of the year.

"In Melbourne we had a strong race and Max was pushing Lewis the majority of that grand prix.

"Bahrain was a tough race for us but it exposed some things that we've managed to improve on since then. China was a stronger race, and Baku even more so – and on a track that doesn't historically play to our strengths," added the Brit.

"We're looking forward to heading back to Europe now and we have a few circuits coming up that should really suit us."

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
