Just over a month ago the Formula 1 world was shivering in the snow in Barcelona testing, now we are in the Bahrain desert - and it is hot.

Max Verstappen has had a great time in Bahrain already. He posted this picture of him jet-skiing yesterday. Admit it, it looks great fun.

Chris Marsh aka Rek Arathor: How to improve F1? Figure of eight tracks! That should spice it up a bit.

Christian Withers: Lift ban on active suspension, points for qualifying & reverse grid. Simple.

Gareth Pritchard: Add weight to the winning cars, the BTCC was in the wilderness for a few years but the new structure is making some amazing racing, totally unpredictable.

Ralph MacGregor‏: I would improve F1 by trying to level the playing field and make it about drivers, not cars. manufacturers submits a publicly available chassis and engine spec and then each team pays a sub for the year for an engine and chassis of choice.

Auto Motor Und Sport are reporting that F1 plans for a $150m budget cap from 2021.

The F1 press release contains no concrete details of their proposals at all - only vagueness re cheaper, simpler engines, budget not to define performance, a cost cap, "more balanced" income distribution and "more raceable" cars. Ie, a reiteration of what has already been said.

Earlier today, Formula 1 bosses spelled out their vision for the sport's future to the teams. F1 motorsports boss Ross Brawn explained the plans of Liberty Media, which bought the commercial rights last year, on cost control, revenue and technical rules.

Those plans included ways of cutting costs, creating a more equitable split of revenue among teams, a simplified engine and an increased number of standard parts.

It was the first time teams had heard this amount of detail on Liberty's plans.

The plan had four main aims:

• reduce the gap in prize money earnings between the top and bottom of the field
• cut the £300m+ budgets of the top teams to about half that
• simpler, cheaper engines that reduce the gap in performance between the best and worst, and open F1 to new entrants
• simplify the technical rules to reduce cost by standardising parts that are perceived to have minimal effect on both performance and the show.

And so to round two of 21. Formula 1 has swapped the streets and easy living of Melbourne for the desert of Bahrain, and Lewis Hamilton has his first chance to make amends for his Mercedes team throwing away the first race of the new season.

The question still hanging over Formula 1 is, how easy will that be? Are Mercedes really as far ahead as Hamilton’s stupendous qualifying lap in Australia suggested? Or is it close again between the silver cars and red, just as it was last year. As Hamilton himself says: “We will have a much better idea over the coming races.”

Hello and welcome along to BBC Sport's live text commentary from the opening two practice sessions for the Bahrain Grand Prix.

I'm Michael Emons and I will be guiding you through the action today and we will also have live radio commentary from 11:55 BST on BBC Radio 5 live sports extra.

The race to five. That is how many people are seeing this Formula 1 season as Mercedes' Lewis Hamilton and Ferrari's Sebastian Vettel, both four-time world champions, battle to win a fifth title.

If that is what this season is about, then it is first blood to Vettel as he, aided by a virtual safety car and some nifty work from his team in the pits, won the season opener in Melbourne with Hamilton second.

But it is on to the next one and on to Bahrain for the second race weekend of the season. Let's have a look and see how they are all getting on with the opening practice session.
