There was plenty to take away from a brilliant weekend in Barcelona...
1. New Records
Sunday proved to be a record-breaking result for Lewis in a way he hadn't expected. He's now surpassed the legendary Michael Schumacher as the driver with the most F1 wins from pole position, moving to 41 with his incredible drive in Spain.
"It's still very surreal," Lewis said, when he was told about the new record. "It just doesn't register because I remember like it was yesterday, sitting at home, playing this computer game as Michael!
"There was this game where you could do the entire race weekend on the computer. I didn't have a steering wheel, I did it on two keys and I remember playing as Michael.
"So, it just still is very, very surreal to think that every now and then I keep coming up against Michael in terms of records and it reminds me of what a great he was.
"It's always an honour when his name and mine are brought up at the same time."
2. More New Records
A combination of various factors helped records to tumble at the Circuit de Barcelona-Catalunya, including track resurfacing and the number of upgrades that have appeared across the grid since winter testing.
Lewis put in a spectacular qualifying lap on Saturday to shatter the previous track record in Barcelona, putting in a 1:16.173 on SuperSoft tyres to set the fastest lap ever completed on the current layout.
The overall lap record, which is taken from race laps, was already being surpassed in the first flat-out laps of the Spanish GP (after the Safety Car period). Lewis was the first to dip under Kimi Räikkönen's previous benchmark from 2008 and it kept on decreasing from there.
In the end, it was Red Bull's Daniel Ricciardo who secured the new lap record in Spain, with a 1:18.441 - over three seconds quicker than the old record.
3. Race of Attrition
It isn't usually the case in Barcelona but quite a few cars dropped out of the Spanish GP, leaving just 14 remaining at the flag and mixing up the order along the way.
A first lap accident eliminated three cars and reliability issues caused several others to drop out over the course of the 66 laps, with a few more crossing the line sporting heavy battle scars.
With a number of drivers making errors across the weekend, if evidence were needed that driving the modern era of Formula One machinery is far from a casual Sunday cruise, this weekend was it.
4. Strategy to the Fore
The Circuit de Barcelona-Catalunya is a tricky track for overtaking, making strategy even more important at the Spanish GP. And predictably, quite a few of this year's changes for position took place during the pit stop sequences.
Pre-race, there wasn't expected to be much between a one-stop and a two-stop strategy - although the latter appeared to be marginally quicker, especially with the warmer temperatures. However, dark clouds also loomed in the distance and there was an 80% chance of rain for the start, so things could have quickly changed.
In the end, with the help of the Safety Car and Virtual Safety Car, the tyres ended up lasting longer than many expected, and degradation rates were fairly low. This meant some drivers were able to swap from a planned two-stopper to pitting just once.
5. No Walk in the Park
When a driver is out front with a comfortable lead, it's easy to assume they are taking it easy and cruising to the chequered flag. But that's rarely the case - and it certainly wasn't for Lewis on Sunday in Spain.
There are always threats to look out for, surprises coming your way or race circumstances arising. Lewis was in command but you never know what's going to happen next and he needed a comfortable gap to cover off those behind and scenarios that might come up.
In Valtteri's case, he had the threat of Max Verstappen's Red Bull on much fresher tyres and Sebastian chasing on his fresh Mediums too. He was having to balance the gap to his closest rivals, while also conserving and managing his worn tyres to make sure he reached the end.
No F1 race is easy, but the success is made even sweeter by the journey to get there.
