All this "best Chassis" thing is bollocks to a large degree. It's more how everything, including the engine and drive chain is all integrated into one package, and how they work together. You could argue Ferrari have the best Chassis, and their engine is very well integrated into their concept, ditto Mercedes, even though they're quite different. It's how it all fits together that counts and how the teams exploit and understand their relative cars / packages. So far it seems to me the Mercedes have the best understanding of their car, and are in a position to exploit it's potential the best. I don't think the Red Bull concept suits it's engine, maybe now they have an engine manufacturer who'll work with them towards their design goals it'll get better, but for me they'll need a lot of work. They're way behind where Ferrari and specifically Mercedes are. Singapore isn't the barrometor they should be looking at. Suzuka and CotA will give a fairer picture.
