Of all the car bodystyle types that you can think of, by far and away the most popular seems to be the sedan. Yes, big SUVs and pick-up trucks are quite a common site across the States, but there's no denying that the tried and tested 'three box' formula is one that many buyers in the USA love. It's understandable, then, that many companies have decided to reveal their all-new sedan cars at the Detroit Auto Show this year - only China can lay claim to being the bigger sedan market than America.

Perhaps the biggest (in terms of sheer size, at least) of all the sedans being revealed at the 2016 Detroit Auto Show is the all-new Volvo S90. A replacement to the rather forgettable S80 range, and using the underpinnings of the excellent XC90 SUV as a base, the S90 has the potential to be quite a sizeable thorn in the side of BMW, Mercedes-Benz and Audi. The cabin, for instance, looks like it's going to be extremely well put together, and even Volvo S90 variants on the standard spring suspension setup (an even more comfortable air suspension system is available as an option) have been tuned to prioritize outright comfort over a firmer-riding sportiness.

Factor in the delicious styling detailings (the 'Thor's Hammer' LED headlamp design are as cool as its name is awesome) and the fact there'll be plenty of great engines on offer, and you have the makings of a very special executive sedan. Volvo may officially say that it isn't really looking at chasing volumes with the S90, but we have a very sneaky suspicion that the new Volvo flagship may very well be a big sales hit for the Swedish firm. A new sedan that is definitely aiming to attract as many executive buyers as possible, however, is the new Mercedes-Benz E-Class. And, like the aforementioned Volvo, it looks like a tasty piece of kit.

While we don't know all of the ins and outs at the moment (and likely won't know anything for sure until the car's official unveiling next week),the tidbits we do have on the new Mercedes-Benz E-Class fill us with confidence. Like the Volvo S90, for instance, an optional air suspension system will be offered, which should make the new E-Class a pretty comfortable car. After all, a similar system is used to great effect in the flagship S-Class series, and Mercedes' recent push to a more comfort-orientated approach with its sedans (instead of trying to beat BMW at its own game) gives us faith in Merc's ability to make the E-Class a docile highway mile muncher.

Other snippets of tech from the S-Class should also trickle down the pecking order into the new E-Class - expect to see all the digital dashboard, 'Magic Sky Control' panoramic roof and hybrid drive gubbins featured on the Merc flagship somewhere on the new E-Class' spec sheet. All that we know for certain about the new Mercedes-Benz E-Class, though, involves the exterior and interior styling. We've had the interior officially revealed to us through teaser images, though we have to thank the German motoring magazine Auto-Press for leaking the pics of the new E-Class' exterior ahead of its official reveal. We'll let you decide if the looks are a hit or a miss, though...

Mercedes-Benz won't be the only manufacturer revealing a deja vu sedan design at the 2016 Detroit Auto Show, however. Hyundai is also using the first big motoring expo of the year to reveal the Genesis G90 - in essence, a Hyundai Equus that's been restyled and rebranded for the firm's new 'Genesis' premium sub-brand. As a result, there isn't really much to talk about that hasn't already been said before. Think of the Genesis G90, then, as a stepping stone towards Hyundai's ambitions of turning the Genesis name into a true rival to the established premium names. Only time will tell if Hyundai will be successful with this venture.
