Sometimes bad days happen re: McLaren. If the week offers more of the same I would be inclined to agree. Another <80 lap day at any point and it'll look grizzly

LCFC won the Premeirship and this season are back where they belong. Sadly this doesn't happen once a motor is attached and people are designing the main part of the sport, the car.
Not a cat in hell's chance that in 2017 any team bar Merc Ferrari and RBR will win the WCC and in truth I'd stake my claim that no one will beat Merc to the WCC.
It's all relative, if Merc went out full of fuel and were clearly cruising and Sauber went out on fumes and were ringing it's neck and Sauber came above Merc in timing you'd still clearly know that Merc were better. Its not hard to work out who the best will be this coming season.
Pretending it will not be so is fine but don't expect everyone to want to play along with that.
Motorsport isn't really the place to find shocks for the most part, certainly not at the professional level. I don't think we expect any giant killing scenario's.
No I totally agree that no other team apart from Ferrari or Red Bull will be able to challenge Mercedes for this years crown but if both can challenge and make life uncomfortable for the Mercedes team then at least the new rules have helped the situation.

The tyres are going to be a big feature and perhaps whoever is better on them for longer runs could make a huge difference as it is looking like they are not going to last.

Whatever the case if Mercedes yet again romp ahead in 2017 then the sport itself will only lose more fans and the new owners will have a massive headache.
Sort of agree but also think that Lewis is gaining the sport so many new fans, maybe not true fans in a traditional sense, but fans of Lewis who don't know the full reasons why a guy might be so much faster than the rest on paper (car etc etc). He's big in America and has the most celebrity friends who are considered 'cool'.
I think Lewis winning all the time is actually something the sports puppeteers will be happy with for now. It's the closest F1 will ever get to having there own Valentino.
The worry would be if Merc go backwards and obviously Lewis would go backwards with them and a percentage of the glory hunters would go elsewhere.

Aero rakes, a grid of sensors to measure the airflow coming off the front wing and wheels over the rest of the car. http://www.autosport.com/news/report.php/id/112669

You don't need to be able to read Spanish to figure out the McLaren suffered major borkage.

Will Alonso even make it to Melbourne is testing carries in like that?

Maybe McLaren has something simple wrong with it.

We had problems once with an engine dying on its arse when asking for full power. Took two days to find that fuel pressure was about double what it should be; someone had put the non return valve and banjo end bolt in the wrong end of the engine (supposed to be on the outlet from the fuel rail/galley/injector returns, instead it was on the inlet). It was forcing fuel the wrong way through the valve...But not enough to sustain full power!!

Yep, it's called Honda wink

For a while in the 1990s, the rear of some air boxes had a vent slot in them.

I thought these slots were banned.
They were introduced by the FIA to reduce power. The airbox feeding the engine wasn't allowed to be pressurised by forward engine feed, the slot was used to ensure that.

The teams simply included some clever internals inside the airbox to regain at least some of the lost ram air pressure

I'd forgotten that. They disappeared after a while.

It looks like they're back in a revised form.

Totally different job now.

You can generate forward thrust with cleverly designed energised exit ducts.

You may remember the small chimneys on some 90's Mclaren side pods, that's what they did.

The radiator ducts on the Spitfire did this - and if they knew how to do it in the mid-1930s when it was designed then I'm sure they know how to do it now

Some great images - the cars look great until the noses of all but the Merc and TR, if they could all copy these two nose designs the whole field would would be beautiful.
  • I may even let RB off... and Ferrari need to have a think about those side pods!

Unfortunately the speeds involved in F1 mean at best you negate some of the losses from the radiator drag.

The chimney is there to vent hot air from the sidepods, with the lower, wider rear wing, taller diffuser and wider tyres it makes more sense to loft some over the top rather than at the rear of the car now, especially as the T-wing can ensure it doesn't interfere with the rear wing.

Here's something they are scratching their heads over at f1technical. The Red Bull was fastest in the speed trap yesterday, which is not the usual RB way of slower on the straight and faster on the bends because they have the downforce sorted, and good going for something with a Renault (TAG Heuere) engine. These photos show the RB and Mercedes on the straight, with the rear end squatting down. That's fair enough for the Mercedes because the DRS wing is closed, so it's got full rear downforce. The RB has its wing open, and the standard ride height for it has its rear end in the air, and they've got it to squat at least as much as the Mercedes.



Might be an aero trick? They are trying to work out what the hole in the nose does too.

Aj - dont forget it's an all new Renault unit.

The development curves will inevitable start to close as the technology evolves

I'm amazed at how much better looking the cars are on the track than in all the fancy promo shots from the launches.

From the rear, the look - dare I say it - like 'proper' racing cars; like the ones I used to draw when I was a kid.

It's probably the fact that they are wide - like F1 cars from the mid 1970s onwards up until the regulations narrowed them 20 years ago.
