    Here's one for Scarb's & SC ((& all you F1 fans (especially F1 engine engineering fans)) Why don't any F1 teams/engine suppliers use liquid to air intercoolers with petrol as the liquid medium? I think the packaging advantage ((no water or air radiator (w to a system)(no massive air radiator)(a to a system)). You don't have to carry water cooling system as the medium is already onboard. I'm sure there are regs on how cold the fuel/petrol can be, but I'm sure if is was at its minimum it would have a decent cooling effect added to this the huge weight & drag savings....

      @Shaun Stephens cool, but that was a separate entity, bring Daimler /Merc themselves. Motorsport wise, engines were always built by AMG, and staring in the 80’s, contracted to ILMOR for their Indycar ( badges as Chevrolet) and F1 engines, starting with the 1993 Sauber V10. ILMOR was bought out wholly by Mercedes in the V8 era….

    A few questions for you and Scarbs. 1. How much impact does the airbox structure impact the effectiveness of the rear wing in F1? For example, Red Bull's Azerbaijan stepped rear wing seems to focus on generating downforce at the centre. Would the air box allow aero downforce to be generated at the centre at slow speed (eg 200km/h) reducing high speed drag? How much does Alpine's "I ate the cookies" air box alter this flow vs Red Bull's. 2. F1 ICE air inlets physically alter across the rev range to better tune the engine performance. What sort of length adjustment is made, and given the rate of rev change in F1 ICE's, how is this physically done? 3. Could a Ducati MotoGP Holeshot style manual suspension lowering system work on an F1 car, lowering the tail out off the line, and out of low speed corners? Would it be legal? I recall Martin Brundle making a comment about a car sitting down at the rear entering the main straight at Monaco (on replay at the time I agreed that it did look lower than normal).

Side in the late 60 or early. this is not new.

    imagine to optimize a VW beatle boxer engine with actual tech but somehow stick to the layout of the original motor block. new materials, 3d printed light weight pistons, prechamber injection and ignition, port injection, isolated output ports to transport maximum heat to a turbo, combined with an electric generator. a compressor driven from an electric motor, or two. but maybe keeping it air cooled?

    A crucial part they skipped over is how the Honda engines were designed pre-2017. The most ingenious thing and perhaps dumb at the same time, about the size-zero engine was that the turbo compressor was within the V-bank. Also it wasn't just a normal automobile turbo compressor, it was an axial compressor. Obviously it failed but had it worked it would have been sick af.

    I’m pretty sure that Mercedes were doing illegal oil burning in the first 4 years or so of the new formula. It’s the only rational explanation for how they were 2.2 to even 2.5 seconds a lap faster. They were very careful to not show this off, but when Rosberg and Hamilton were going at each other it would be on display. It also explains the “party modes”, where they could dial up as much power as they needed. I find it hard to believe that every single other team were incapable of giving them trouble. Not till many years later anyways. The fact that Ferrari had to result to flat out cheating to contend is very telling.

    Brake magic a bad idea for Mercades ? This is what was suspected in Bottas failure in monaco to remove the wheel from the car. This same process of over stressing the materials by excessive heat in the hub fused the wheel onto the car making it impossible to remove it duuring the race. This could have been brought about by driver racing style,track tempertures,the tight layout of the track, or leaving the brake majic on in the race.

    As my 2010 c-class already had a turbo, I’m surprised merc hpp had to approach the truck division for insight to turbos. Im not too familiar with them in themselves, but is it correct to assume that has something to do with the compression/boost being more on par with trucks than with road cars?

    7:30 When a rumor starts saying Mercedes engineers didn't know much about turbochargers in '2013-2012', you know it's not true. One of the key moments for Mercedes was designing and testing turbocharged engines in 2011 without knowing the specs. In 2012's summer break the FIA/F1 announced the engine specs for 2014; Mercedes was already ahead at this point.

      Honda appears to be saying that the F1 engine program has dragged on their efforts to make the whole company carbon neutral by 2050, even though I won't be around by then anyway LOL. I'm assuming when they say they have reached agreements with Red Bull to use the technology what they're really saying is Red Bull is going to pay out the ying-yang for use of the technology. Also, they're going to continue to develop the engine until the end of this year and if one is freezing engine development next year so red bull will just be the manufacturer of the engines that Honda House designed. And I wouldn't be surprised at all if Honda engineers are offered but loads of money to work for Red Bull in the manufacturing plant to make sure it's the same as the Honda plant. I've heard Honda came up with a bit of Material Science Magic in developing coatings for the cylinder walls and other internal parts of the new engine with less distance between the cylinders. I've even read that the new engine is so efficient put the exhaust gas temperatures are enough lower that there's less energy to be captured by the turbo. Not a bad position to be in to be able to make combustion less efficient so the turbocharger will work better.
