Nico Rosberg extended his championship lead after he became the first Formula One driver to win in Azerbaijan on Sunday.
The German driver is now 24 points clear of his Mercedes team-mate Lewis Hamilton, whose afternoon in Baku was blighted by a technical glitch.
Here, Press Association Sport looks at five things we learned from the European Grand Prix.
RADIO SILENCE WAS SOMETHING HAMILTON WANTED
Hamilton claimed the sport was robbed of a stunning comeback drive in Baku after an incorrect engine setting thwarted his recovery from 10th on the grid. With hundreds of different options available on his super-complex steering wheel, and Mercedes forbidden from telling Hamilton how to resolve the problem, the world champion could manage no better than fifth. The Briton described the situation as "dangerous" - he spent 12 laps fiddling with his steering wheel at speeds in excess of 220mph in hope of fixing the issue - and subsequently questioned the FIA's recent clampdown on radio communication. But Hamilton cannot have it both ways. The ruling is there to place greater emphasis on the driver rather than the pit wall - something Hamilton has long been an advocate of - as well as punishing mistakes. And that is precisely what happened in Baku.
ROSBERG IS BACK IN CONTROL OF TITLE RACE
Even without his engine drama, Formula One's first foray to Azerbaijan had been a scrappy affair for Hamilton. The Briton was fastest in all three practice sessions, but suddenly lost confidence with his brakes, and ran off the track three times in qualifying before crashing into the wall. Rosberg, who, had been much slower than his team-mate, snatched the initiative, storming to pole-position before taking the chequered flag. Rosberg's win - his fifth from eight grands prix - was precisely what the doctor ordered after two weekends to forget in Monaco and Canada - and will provide him with all the confidence he needs that this might actually be his year.
SERGIO PEREZ IS MAKING HIS MARK
Wearing a baseball cap and upturned jeans as he waited in Baku's immigration queue for an early-morning flight on Monday, Sergio Perez hardly looked like Formula One's man of the moment. But following his second podium finish in three races - which included a fine last-lap move on Ferrari's Kimi Raikkonen - there will be few who will deny the Mexican his time in the sun. Perez, who is doing his chances of replacing Raikkonen at Ferrari no harm, said: "It's only the eighth race and we've had two podiums already. It's been an incredible year so far."
WOES GO ON FOR JENSON BUTTON
While Perez has starred this term, his one-time McLaren team-mate Jenson Button may well be questioning why he bothered to hang around. The 2009 world champion, who, after much deliberation, chose to extend his career into a 17th campaign , qualified a lowly 19th in Baku before finishing outside the points. After eight rounds, he has scored a paltry five points.
TIGHT AND TWISTY CIRCUIT SERVES UP STRAIGHTFORWARD RACE
Formula One was braced for a chaotic race at Baku's super-quick and twisty street circuit, but there was not one single accident in a grand prix which failed to live up to the hype. In contrast , the GP2 support series race was a frenetic affair with Antonio Giovinazzi, last at the end of lap one, storming to victory. "I think all the drivers probably watched the GP2 race, scared themselves witless, and behaved impeccably throughout the grand prix," joked Red Bull team principal Christian Horner.
