The new B58B30M2 engine (already in use on X5 LCI and G60 5 series) is such a big upgrade they might as well call it the B59. It added dual injection (similar to D-4S) and eVANOS with Miller cycle operation (similar to VVT-iEW) so it's now the most technologically advanced mass-produced ICE. The mild hybrid system also changed from BiSG (P0 hybrid) to CiSG (P1 hybrid) for better regen and boost.
Getting 130PS/L and 193N.m/L from a 11.0:1 compression ratio on a turbocharged engine is very impressive. The almost-perfect ICE is now even better. I really hope Toyota step up their ICE game with the new generation they demonstrated recently. The G16E-GTS is a good starting point. Now they need to double its cylinders.

Appreciate the technical goodies you post!
The interior of the x3 is very basement bargain feeling shrouded with lots of distractions like leds lights and screen and really sharp angles. I wish they spent some more money with wood trim or even glass inserts. The exterior is good minus the rear that takes some inspiration from the xm...smh

I like the exterior A LOT. First good looking new BMW release in a long time.. it's embarassing that BMW now designs better looking crossovers than cars.. the new X1 and X3 look better than the new 1er, 5er, and 7ers.
That being said, the interior is mad disappointing. Looks like major cost cutting took place and it looks like a dark and cheap place to be in.

Excellent post @ssun30. Well said.
I'm not too crazy about the exterior but that interior looks... mid-2000's? It also looks like they took interior styling cues from the Toyota bZ4X, which is not a bad looking car on the inside, is just not a car they should be mimicking.

This is very exciting stuff. After driving the B58 (Supra), it's hard to think of any other powerplant in such high esteem: MPG of a 4 cylinder, power of an 8 cylinder, no lag, power everywhere, and very reliable.
The new engine being an improvement on that is hard to fathom, but I'd love to verify personally

V35A-FTS is an example you can't throw technology at an engine and make it good. Technically it's more advanced and was released 7 years ago. In reality it's the most problematic engine Toyota has designed this century.
Im sending you over a flame prevention suit...just in case
You think they're gonna cut their losses and replace it sooner than later?
It's not new for Toyota to stop production of engines with reliability problems just a few years into production. People only remember the ones they do keep in production for decades.
The first and second generation D-4 engines (direct injection only) were discontinued in less than 5 years because of bad carbon build-up and injection pump failure (1JZ-FSE, 3S-FSE, 2AZ-FSE, 3GR-FSE). The 8NR-FTS was in production for just 7 years despite being a high volume mass market engine because its intercooler tends to break. The 6AR-FSE was discontinued in just 5 years and it didn't even have a lot of problems.
