There's any number of supercar and hypercar silhouettes which would conceivably work as a Batmobile, with a few amendements and additions - not to mention, painted in black.
I get the argument that sometimes we have to let go of realism; that a cape isn't a practical thing for a superhero to actually have, so why not drop it if we're going down the realism route? But I see the Batmobile as a very different proposition. Fight scenes and so on can be shot without a cape and it can be added in post production nowadays with CGi.
But unless a Batmobile is filmed entirely using visual effects, it's going to be incredibly impractical looking onscreen (not to mention impractical in terms of actual live stunt work) for it to have the ground clearance of a typical supercar or hypercar. I'm not talking about extremes like scaling rough terrain or clambering over rooftops like the Tumbler did. I'm talking about even basic, fundamental scenes like driving down an average off ramp from a parking lot, which a Lamborghini or Ferrari struggle with unless driven at a slow pace and at certain angles. For the type of driving Batman will be engaged in, the car needs ground clearance - and when you elevate a supercar or hypercar's suspension to allow ground clearance, it looks ridiculous. When it has a military connotation however, it doesn't look ridiculous.
Now with that said, if the vehicle's suspension was adjustable mid-drive - that could change things completely. It could be raised by Batman when needed, and lowered for higher speeds on smooth surface.
As I mentioned in an earlier post, I also think this next vehicle should be fully electric, for a multitude of reasons.
I think there are a few things to factor in, for instance here you set your chase sequence, then the fact on these movies when they have a special car they only use the real one for selected shots and it's known as the hero car, the rest are often bodykits bolted onto cheaper cars with good chassis for the actual stunt driving, then it's down to shot selection and the editing room to sustain the illusion.
Most Supercars and Hypercars have a lift mode these days to raise the car up to go over bumps, but I'm not sure at what speeds it can be activated.
However the technology is there and in the case of Batman you can simply say he's advanced the tech to activate it at high speeds and you use your editing to make that work. The design below that BobJM posted looks like it could believeably have some trick suspension, like have you seen the motorbikes in Hobbs & Shaw? I was thinking something like that with this car.
As far as it being electric, Tony Stark drove the Audi e-tron GT in Endgame and like hm Bruce is always on the cutting edge of technology development, but I can see the counter argument of the lack of engine noise would dilute a chase sequence. Maybe a hybrid could be the way to go, so Batman can go into stealth mode just using the electric motor and then the engine kicks in as the chase starts/continues and of course the electric capacity combining will give incredible acceleration.
In the pure scope of realism, even the Tumbler or Snyder-Mobile wouldn't be realistic or practical either. Both of them are insanely wide so basically to beat either Bale or Affleck's Batman in a car chase a narrow street or ally would lose him. Not to mention the pair of them probably handle like a bus & realisticly those things probably would have a relatively low top speed overall as in 100mph or less..
I'd be fine with them going with a more sporty version of Batmobile along the same lines of
the shameless car porn you've posted 
, however I'd like the panels & whatnot to not have such a fancy paintjob, matte black or even have a similar functional aesthetic to the Snyder mobile basically to give the illusion that it's not a fragile hypercar.
Fair points, there are the odd big vehicles that handle pretty well, like the Lamborghini Urus, but it's in context of what it is, the Snyder Batmobile looked at least like it would go fast, the Tumbler's strength was acting like a monster truck.
Just some visual aids!
I agree that the paint job needs to be all black, I was really just showing examples of some of the radical designs out there, like the Aston Martin Valkyrie, that could serve as a starting point more than as something to use as is. The concept below as anm intereesting mix of styles IMO.
My Dad saw this on a video I was watching the other night and remarked "It looks like a Batman car!" His nerd vocabulary is not up to scratch.
