Interesting. So DI vs port isn't just load dependent, it also varies in output depending on piston position?

That will make tuning fun...

Nice they explained everything like I was five

So, absolutely no substance to the aero video. Just "These are aero parts. THey make the car go better!" I was hoping for more.

The animator for the second video has no idea how a 4 stroke engine works...

Did anyone notice the headlights at 0:25 and 0:41 ? The car carry's a scion badge and has the LED headlights and fogs...interesting

We will get HIDs one day...probably model year 2014...

I had no idea the "aerodynamics" were so involving to the design of the car. To me it just looks like a sporty 2 door coupe..

^ haha agreed. The commentator sounded like he was reading from flash cards, and the info was aimed at kids in a science fair.

i noticed the LEDs on the scion, but anyone notice the engine near the end? what engine is that? looks like a v6

Yeah, but they also showed it having the 18 inch prototype wheels and a 6 cylinder engine. So it's just a mish-mash of pics and I wouldn't read much into it. However, there is still one official Scion pic with LED's so I'm hoping they will indeed include it for next year.

So this video says it only uses the DI at high speeds yet the other Toyota videos I've seen said it uses DI only at mid speeds and both DI and port again at high speeds. They are probably going off of the documentation for the previous generation D-4S.

Somebody commented it's the Subaru EG33 6 cylinder boxer engine.

Speaking of which, can you imagine if the FR-S had one and sounded like this?

that fuel injection system needs to be refined, that nasty Torque drop at 4k rpm sucks ass!
