McLaren MCL33 Speculation thread

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

Autosport interview with Tim Goss:

McLaren technical director Tim Goss is confident his team has successfully overcome packaging headaches caused by Renault's engine architecture without having to compromise its 2018 Formula 1 chassis design.

Although switching from Honda to customer Renaults should provide a power boost for McLaren, Goss revealed that the different packaging of the turbo and energy recovery systems required major work to accomodate.

"The Renault architecture is very different," Goss told Autosport.

"You have two fundamental engine architectures out there. You have the Mercedes/Honda approach, and you have got the Ferrari/Renault approach.

"Essentially the difference comes down to where the turbocharger sits.

"The Mercedes/Honda approach is you have the compressor on the front of the engine, the turbine on the back of the engine and the MGU-H sat in the middle of the V.

"The Ferrari/Renault approach is that you have got the compressor sat at the back of the engine, the MGU-H behind it and the turbine behind that.

"They require a very different approach to your chassis and your gearbox, and now we have had recent experience of both we can see there are pros and cons of both.

"There are things I love about the Renault approach and there are things that frustrate me a little bit, but in the end we were fortunate that the decision to move from one engine to another was made just in time.

"It couldn't have been made any later."



Packaging the Renault has had an impact on McLaren's fuel tank, gearbox and rear suspension.

"We had to reconfigure the chassis, change the cooling system and reconfigure the gearbox to make it fit," Goss said.

"But we've managed that in time without any significant compromise to the chassis. It was quite a big change.

"The Renault engine will sit further forward in the chassis. With the Honda you had the air intake that had to come down into the front of the engine, and that volume came out of your fuel cell. So as a result, the chassis was longer.

"But then what you hadn't got was a turbocharger sat off the back of the engine, which then gets in the way of your inboard suspension.

"So you ended up with a much easier task at the back of the engine.

"When you move to a Renault, suddenly the front of the engine becomes a lot simpler and as the result we win back a substantial amount of fuel volume.

"You can push the engine forwards and the aerodynamic blockage of the engine and exhaust is considerably better, because that has moved forwards behind the chassis.

"But then you have a turbocharger that is sat in the bellhousing and to accommodate that you have to redesign your rear suspension internals and lengthen the gearbox.

"But we've done a fantastic job. A really fantastic job.

"It was very, very intense. We had two weeks of very intense effort to get it sorted, but we knew pretty much what we needed to do."
I wonder if they can come up with a solution different to Renault and Redbull.

Does this mean that the Renault PU offers better center of gravity since the engine itself is more situated more forward/middle in the chassis?

It does sound that way although the wheelbase of the car would have t be taken into account. There is a bit more pipework to deal with using the Renault/Ferrari method so the total PU-related package probably weighs more.

I think this is relative to what the MCL32 had, there is much leeway in the general design, how long/wide/etc you make your tub/fueltank and how far back you construct the gearbox. I think you could say that Ferrari/Renault can have a bit more space behind the driver to the ICE compared to Mercedes/Honda.

No idea what you're on about.

Bruce's first car (Austin 7)
Hunt's 76 championship car (M23)
Senna's 88 championship car (MP4-4)
Hamilton's 08 championship car (MP4-23)

Each one easy to identify...

...but then again just like your "no one allowed to talk about the budget gap" post you're probably just here to provoke. :D

Like ot or not it is a Mclaren Honda on the add and I find it funny they use as it os one of the most recognazibles cars of history, specially when they are departing from Honda https://www.dropbox.com/s/vl0y2evuvz3ch ... 7.png?dl=0

I stick to the subject of the trend. :wink:

Why shouldn't it be in, they have great history together and this shouldn't be ignored or forgotten just because it didn't work out this time.

Nothing strange or funny in there. Just you trying to provoke/troll.
Either that or you're just bitter about McLaren ending the Honda partnership.

I think for most people who’ve been around a bit longer, it’s not the McLaren-Honda that stands out, but more the McLaren-Marlboro, what some people link to Honda... while there was also Ford, TAG and Peugeot (and even a year of Mercedes)

No trolling I work on marketing and for sure it has an amicable message behind it, specially as how the video has been edited that's why I find it funny.
On the team trend I spoke about the budget because it is a concern but speaking openly and debate without being tagged of hater or troll is not possible apparently
