Engine noise level
#46
How many of you heard the noise of a Hybrid engine? I bet you none and this includes me. This is what i'm meaning to say about engine noise whether it's the fan noise or whatever. I am 100% sure that a lexus (if not GS, the LS) is hybrid like in terms of engine noise at idle and no it's not the new Hybrid GS. One of the Lexus features I have always praised is this quietness of the engine
So, hybrids will/should have Zero engine noise (other than fan maybe)

Noise of a hybrid engine... umm... i dont go near hybrid cars to hear the motor, if one passes me while im walking in a parking lot my eyes may see it but then the brain doesnt register it...
Its like the differance between hearing and listening, you hear your gf/wife saying something, 'babble babble babble, ok dear?' so you respond with, 'huh oh yea, ok' all the while flicking the remote on the tv looking for something to watch.

You guys have got to be kidding me! A stock ISX50 is probably one of the more quieter cars I have ever gotten my hands on. That is one of the reasons I bought the car then I realized it was to quiet so I got the Tanabe. Guys just enjoy what you have and don't expect perfection including from an automaker that makes BMW look behind them.

I also meant while it's idling and you standing next to the engine, not while you are driving. No complaints from inside and while cruising as i think cabin noise insulation is A1 in the Is.

It's not the fans. They are electric and only cycle when the radiator reaches 210F. The noise you hear is the high pressure injectors, and it is unavoidable with the current technology.
Lexus have done an amazing job of controlling noise in a 306 hp engine. There are any number of design features to reduce noise in the powertrain. However, it is impossible to make a high pressure injector quiet - at least at this point in time - so you can have your pick: a 306 hp NA engine that gets exceptional gas mileage with a very broad and flat torque curve, or less mileage, less power, less mid-range torque, and quieter idling from another brand.
Personally, the noise isn't nearly as bad as a lot of other cars I have owned.

Thanks lobuxracer, i can now reason anyone who say the car is noisy...it's the injectors.
Speaking of which, does this high pressure injectors exists in 1IS and also on any other cars? I'm gonna do some listenning on cars as i am a partime valet attendant

I do know the new VW/Audi's use direct injection.

No, they are unique to the 2IS in the Lexus line up. Mitsubishi has been selling GDI engines for some time though, and I would be surprised if you didn't hear their GDI engines making the same noise. I would also expect you've seen a few of these in Australia since used Japanese cars are pretty common and pretty cheap where you live.
