I do wonder if that huge grill serves any functional purpose, e.g. a massive sensor array or something.

It is likely similar to BMW's current drive assist technology that has been displayed throughout the G-Chassis vehicles like the X5, X7 and 3er.

As for sensor/radar locations, the i4's is the same as the normal 4-Series and housed in the lower right portion. For the iX it is also featured in the grill, however they are not the reason for the size of the grills as the sensors/radars themselves are not incredibly large. The grill size is purely an aesthetic choice by BMW with a large portion being non-functional.

I hope it looks better in the flesh. Personally I think it looks a bit flabby.

It's just ridiculous. It's both soft (gets out of control at high speed) and too harsh (no travel, hard bump stops) and lacks pitch control (pogos over every damn thing in the road). It drives me nuts. I've never driven a car with a worse suspension. OK, maybe that's a SLIGHT exaggeration, but a car that does 0-60 in under 3.5 seconds needs a suspension to cope with that power.

But that's why I'm here on a BMW forum interested in the i4 to replace my Tesla. Coilovers sure would be cheaper, though!

If you look at the press release you will see this:

So I'd bet it's pretty close.

Sure but that's the same as the 315 for the Tesla.

All tests are done under the same conditions so the 315 of the model 3 will be under same of the 240 of BMW.

Yeah I am interested in reading about the actual hardware firepower that will come with i4 and iX.

[iatacs19]

Need to see the real world test for true mileage. Overall it's a very good effort, at least from what BMW has revealed so far...

Me too! At least they will both have radar unlike some other EV manufacturer that starts with a T

In the real world, EPA estimates have not been consistent between manufacturers. Tesla always have the most optimistic range estimates compared to everyone else. https://www.edmunds.com/car-news/ele...s-edmunds.html

If we go by European WLTP range estimates, the i4 matches the Model 3 range.

Model 3 SR+ = 278 miles
Model 3 LR = 360 miles
Model 3 P = 352 miles

i4 40 = 367 miles
i4 M50 = 316 miles

That promo video needs a cut of our luxuriously-delayed EV couple an hour later, when they're still staring out into the ocean. He's checking his watch. She's tapping the toe of her Louboutins. Charge indicator shows 68%.

A caption reads: "WARNING: Charger location quaintness may vary."

Take a look:

I think that's only due to lighting. In photography you want good light coming from behind to light up the object. These videos are shot where light is very poor, or light is coming directly into the lens making it harder to see the details. These videos are mostly accentuating the leds and lights. The vert video was shot in a tunnel!!??! I have a vert and it's about driving under sunny nice weather maybe a cool breeze. Not in a tunnel or when it's getting too dark to see anything. Anyway, I felt sorry for the advertisement company. They must have sweat a lot.

In other words, you didn't really say anything valuable about ICE or EV cars.

On the contrary he did. He said "buy an ICE until EV's are sorted".

I think that is a sensible advice.

One concern of i4/iX is the non-home charging option.

Now that the administration plans to revamp the EV credits and technically can mandate the supercharger network open to all, as $1.5B(and up) taxpayer money was already spent to build that up.

Well there are some iX's driving around Munich which are part of the self driving test fleet. I think the iX has everything it needs for Level 3 Automatic driving (including Lidars) but as bmw stated, they are waiting until there is a legal basis for it in the major markets. But regarding the i4, I guess it is on level with the 4er.

What's really surprising to me is that the i4 wheelbase (and I guess the 4er GC G26 as well) is just 4mm longer than the G20-G23 according to the tech sheets that BMW published.

I assumed it would have the same wheelbase as the G28 (so much more rear legroom), but this does not seem to be case - so the G26 is much more of an F36 than an F34 then after all.

I haven't found the G28 specs online, but I think press reviews of it claimed it had an 11cm (or so?) longer wheelbase than the G20. Wonder what the i3 will have as an wheelbase when it is out next year.

[RPiM5]

If the range of the i4 had been over 400 miles I would've had more interest. Same for the Audi E-Tron GT, same for the Taycan. Most Americans who will be buying these cars will have another vehicle they use for longer road trips, but most people cannot afford two cars or have a place to park 2 vehicles. This and the fact that all of these Electric Vehicles are over 5,000lbs makes it a no go for me. Lol!

[Pentium]

A step in the right direction, I will wait to see it in person, now I need to hasten the process of getting the M3!

Why is not chargeable at home?

Some may not have the L2@garage, or no garage at all, so public charging is primary.

I haven't seen official BMW press talking about the grille, but this article says iX(and i4 too?) has a high-tech grille:

“Camera technology, radar functions and other sensors are integrated seamlessly into the grille behind a transparent surface,” BMW wrote. Mechanisms to clean and heat the sensors sit in the front of the grille.

That’s noteworthy enough for collision repair. But BMW’s just getting started. This is George Jetson’s grille.

“In order to guarantee the greatest possible precision when using the radar sensor mounted behind the kidney grille, a nanoscale vacuum-based coating process is employed in its manufacture,” BMW wrote. “Here, the two-color finish and visible 3D effect are produced by vaporization using laser technology and by a plasma-fired application technique in a vacuum. A combination of the laser-based method developed specially for production of the kidney grille on the iX and a precisely defined combination of material and layer thickness optimize radar performance.”

Oh, and the grille can also heal itself if you leave it alone for a while.

“An additional polyurethane coating reduces the kidney grille’s susceptibility to damage,” BMW wrote. “The self-healing effect of its surface can repair minor scratches, for example – within 24 hours at room temperature or through a five-minute supply of warm air.”

BMW called the grille an example of “shy tech,” features incorporated into the vehicle subtly enough that they go unnoticed until you need to use them.

That's iX-only I believe, the i4 basically has the same grille as the 4er with that off-center radar sensor camouflaged by some cheap plastic.
