That still doesn't make it a negative rake on the Renault though

I never said it was negative rake. I said it was antirake.

Care to explain what antirake is? Never heard of it and google doesn't give me any results. How does it relate to negative rake?

"We've had the best winter of the last five years," said engine boss Remi Taffin.

the team admitting the RS19 is still being built ahead of the February 18-21 test.

So they do an event to show the old car with a new old livery. Strange that all the small fish is doing it while the big sharks will show the new car straightforward, cute.

Abiteboul acknowledges that there is a lot to be done on the chassis side to catch top 3, and praises engine a lot

Just like they do since about 2014 ;)

It's different this year.

 

Courtesy of AMUS - https://www.auto-mot...9-f1-auto-2019/

Chief Technology Officer Nick Chester is confident that the RS19 can live up to expectations: "Above all, we've been concentrating on putting the units closer together and reducing weight. We will be able to add significantly more ballast to play in 2019. "
When it comes to aerodynamics, the first pictures in particular reveal the new side box shape, which follows the trend of Haas and Toro Rosso with the cooling holes located high up. The baffles on the flanks have also been modified. They are no longer running in a round sweep from the bottom up but square.

The rear wing on the yellow and black racer is now as on the previous Ferrari on two stilts. This helps with controlled bending under load. Between the stilts there is a kind of monkey seat above the exhaust. Blowing the underside of the rear wing, as Renault operated last year, is excluded by the new regulations. The tail moved 7 centimeters upwards.

 

To accelerate the pace of the season, a new test rig was developed at the engine factory in Viry-Châtillon, France, with which engineers can test the complete powertrain together with the rear of the car. He should soon go into operation.

Gary Anderson's question marks over the new Renault

 

https://www.autospor...the-new-renault

 

No idea what's in the article as I won't pay for the drivel he comes up with but this has to be good news for Renault fans, if Gary Anderson doubts your car you've definitely build a good one!

Will Buxton: Abiteboul lays out in no uncertain terms the road ahead for Nico Hülkenberg. “It’s make or break.” Has to impose himself and perform against Ricciardo if continuation of relationship with Renault is to be successfully concluded once talks begin later in the year.

Antirake is when the rear is higher than the front.

Negative rake is when the front is lower than rear

Jake Boxall-Legge from Autosport.com:

 

Of the cars launched so far, this is one that's perhaps expected to change the most between launch specification and what will actually hit the ground in testing and at Albert Park. And if it doesn't change too overtly, then Renault's attempts to draw closer to the front three can be described as conservative at best.

Can someone summarize in one sentence what issues with Renault car Anderson has?

The car shown today is a computer model, still in the computer.

Because it has livery, material, animated and so forth, It could very well be a model that is some weeks old.

 

I am thinking that we will see much different car in testing...

Not that hard, Renault aren’t exactly the benchmark PU wise. Renault being in front of Red Bull in 2019, now that is hard to expect.

All this technical analysis at this point in time is pointless. We all know these guys come to Melbourne with practically different cars (aero-wise at least). I know we all love to get telling insight, but it really is pointless at this stage, so Gary A or anybody drawing conclusions at this point is simply because paper can't refuse ink ...

 

Want a reliable test, plenty of laps and running, don't care about times ...

They had a better engine than Renault already last year. With the amount of money Honda is spending on their pu development it's not impossible that Renault will have the worst engine this year.

:lol:

facepalm

 

Better in what? even to say "the Honda had more power" is sensellss... let alone reliability, race craft etc. 

So to say "it was better", is one of the lamest jokes ever.

I'm not expecting them.

 

I'm expecting Renault to produce significantly better engine (and aleary having a better engine) thus reducing gap to RBR by quite a big chunk of it.

 

Add to that Honda engine unreliability and I really think Renault can take fight to RBR

Nope.

The physical car was a modified 2018 car.

The render is the RS.19 car, but simplified, with some parts removed, like the under-nose vanes.

Why? Who is this Red Bull guy? And why they should be considered untouchable and standard? Just so sick of this presumptions what someone can do or can't do.

Because the chassis gap to RB is too big and cant be closed in one season. 

Ricciardo and Renault said last summer that RB should be ahead them in 2019.

Mate, even Renault themselve expect Red Bull to be in front. I'm digging  the good vibes at Renault but you're setting yourself up for a world of hurt next month when the RB's will be dissapearing in the distance yet again. 

2020 will be the year they aim for podiums. 2021 and on is where they expect big things to happen.

 Because Red Bull can consistently build a car with the same engine and win races, where as Renault can't find the podium.  Then factor in little evidence of the required changes at Enstone to reverse that.  1+1=2

 I suspect the fact he's not noticed to many changes between the 2018 and 2019 cars is because he didn't realise he was looking at a 2018 car with 2019 elements on it...

Bearing in mind the wailing and gnashing of teeth about the huge effects of the new front wing regs both the new cars we've seen so far are pretty close to last years aerodynamically.

f you on that opinion. RB was winning races immediatly 3 years into F1 and everyone expected them to force, right?!!!!!!!!!

 

You expect people to give the benefit of the doubt with this recent history??

 

2016 - 2 wins, 15 podiums, 468 points vs. 0 wins, 0 podiums, 8 points

2017 - 3 wins, 13 podiums, 368 points vs. 0 wins, 0 podiums, 57 points

2018 - 4 wins, 13 podiums, 419 points vs. 0 wins, 0 podiums, 122 points

 

With that trend maybe Renault will score half of Red Bulls points this season?

 

I admire your loyalty but get real.

It is used in skip barber. It was used in 60s. It was used in formula Ford.

Basically it is/was used every where where you had a light car with little or no downforce.

 

Great way to react on only a part of a post.

Positive rake angle is higher end, and negative rake angle is higher front of the car.

You said it was the other way around. I think you are wrong.

 

Setup guide on a Formula ford:

https://firmtec.word...mula-ford-1600/


The final tactic was to reduce the rear ride height to the legal limit so the car ran level instead of with a little rake

So higher rear end = positive rake

They lost the latin alcohol brand, but Renault did a great job cleaning the livery up this season.  It's crisper and better put together.

It's a Spanish company, Carlos Sainz Jr's personal sponsor. So, it's not really a loss.

Rake rises the front

But the engeneering process is completely different

Wow.. guess the rule changes Renault feel do not make any real impact in their design approach from last season... RB Horner made it seem it was a great expensive to redesign their car.. guess Renault do not share the same opinion.  Hopefully, the engine gains are real because they didn't have the most stable car last season so hard to see how they've tweaked this car to address last seasons issue... unless it was all due to poor aero off the front wing..

I totally agree with you. But in 2019 there is substantial change compared to previous years: different PUs will power them. This might change the playbook a bit. Maybe Renault finally delivers something really good and Honda not, then game on. But the opposite can happen too.

But purely on aero side Renault will not match RB in 2019, that's for sure.

I think you've got some things mixed up. Do you work for Renault perhaps? Would explain the huge amount of rake.

Renault: "We want less rake this year"

BiggestBuddyLazierFan: "No problem, consider it done!"

The grapevine suggests Renault have found 35kw (46bhp) gain in qualifying trim and 20kw (27bhp) in the race. If so, this would put them close to the level Mercedes and Ferrari were at in 2018, although no-one thinks the top two won't find more performance over the winter.

I think you're rather mixed up, but that particular post was describing the same thing from two different sides. Sort of "heads I win, tails you lose".
