    Toyota will be changing their aero for 2018. I hear it is even more futuristic looking than the current car.
    Wales is definitely not tight and slow, watch some of the many youtube videos and you will see they are often going quite quickly

    Evans' average speed in Wales was 103 km/h which is pretty average for a gravel rally. Finland was 126 km/h, Poland 116 km/h, Argentina 98 km/h, Portugal 94 km/h and Sardegna 91 km/h. Wales has fast sections, but also lots of tight hairpins.

    You don't need any aero in hairpins but You need it in fast sections. If a stage has a lot of slow points like hairpins and junctions and still has average speed over 100 km/h it's in fact pretty quick. The sections between those slow points have to be of much higher average speed than the stage as a whole.

    Evans had covering plates on the wheelarches while Ogier and Tanak had them at least semi-open... why?

    Now I noticed this too. In videos all the M-Sport cars have them open and then taped shut.
    Maybe it has something to to with them collecting mud

    Technical Analysis: WRC Cars 2017

    I tried to look find the answer in this thread but didn’t see one.
    Why are Toyota using 2 radiators? It looks like a radiator on either side of the intercooler.

    Is it possible that the Toyota suspension components are machined hollow and then filled with some sort of structural foam? I don't think that would technically be called a composite material, so it seems like it would be a way of getting some of those properties (lightness, rigidity) while avoiding the regulation.

    From pure technical point of view (i.e. disregarding the tech regs), in theory yes, but in practice very unlikely, as the current state of the readily available structural foams is such that their stiffness is significantly lower than the steel that the wishbones are made from. Maybe if you were to use a 3D metal (i.e. steel) printed lattice attached to the inside of the wishbone skins, then you might be onto something.

    I often wish I'd stayed in engineering school. I hate technical 'anoraks' but I do love technical things, like this thread.

    Love this thread.....Looking forward to observations regarding the changes between the 2017 and 2018 cars. What are you guys seeing that a newbie heading into his second season of love for this sport should know? Who has made the most changes?
