Jerez first 2014 test Test day one

The first engines fire up down in pitlane.

Curious to know what they'll sound like at full chat? Our man KEVIN TURNER is down at Dry Sac, and will be bringing you the low down on what the new era of F1 sounds like later today.

We're 10 minutes away from the start of F1 2014, and all the unknowns that surround one of the biggest rule changes in the sport's recent history.

Which is as good a time as any to remind you that we'll be bringing you live updates across the four days at Jerez, covering every lap of on-track action and all the latest news and gossip from the paddock.

It will also be fascinating to see what times the cars are capable of, and how spread out the field will be – even if the usual disclaimers about this being the first day are more pertinent than ever.

As a reference, Jenson Button set the pace last year with a 1m18.861s, with all 11 runners covered by 5.315s.

The sweeping rule changes will also have a massive impact on what teams are hoping to achieve on this first day of testing.

Last year, for example, Paul di Resta completed 89 laps on Force India's opening day.

AUTOSPORT's technical guru Gary Anderson reckons hitting a quarter of that tally today will represent an impressive start.

Of course, all the focus this morning has been on the appearance of this year's designs as Mercedes, Red Bull, Force India and Williams all rolled out in the pitlane ahead of the start of the test.

You can check out AUTOSPORT's gallery of every design so far here.

Good morning and welcome to the first AUTOSPORT Live commentary of the 2014 Formula 1 season, as pre-season testing kicks off at Jerez.
