Yes, the Lexus engine is pretty loud. Here are some offical interior noise levels of the BMW 335i and Lexus IS350:

BMW 335i
Db @ Idle: 45.5
Db @ Full Throttle: 74.7
Db @ 70 mph Cruise: 62
Lexus is350
Db @ Idle: 40.9
Db @ Full Throttle: 77.2
Db @ 70 mph Cruise: 63.2
The Lexus is quiet during idle but for some reason it is especially noisey at full throttle.

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

Aren't you asking for a bit too much from the entry level Lexus? All you should expect to compare it to are cars in the similar price range and purpose, and for most measures, the IS compares favorably in that range.
You can't compare entry level cars with the top of the line models in the same brand, or else you'd have LS owners complaining that their car is no quieter than the IS.
It's like asking why First Class passengers get better food than coach despite the fact you're both flying on a more luxurious airline (e.g. Singapore, Virgin, etc.)

Why does this matter???
Why do you think the LS costs twice as much?

I know and realised it's an entry level Lexus, and that mine is a base model but what about the top Is model, which costs some $AU20K (around US15K??) ? surely with this price it deserve to be more quiet.

I bought the IS because it was quiet. It was the quietest of all the cars i was looking at and it is the quietest car i have ever owned. I dont think the engine or exhaust is too loud but i wouldnt mind even less road noise, thats for sure, texas roads suck.

I can drive my car and listen to the engine sing all day long. However, the exhaust noise coming from the g35 is intolerable to me. I want to hear pistons pumping (especially when driving stick), not the fart-in-a-can exhaust that some people seem to like. For me, this is just plain rice.
The base IS has a nice subtle tone coming from the engine compartment, though it is far more quiet than its competitors. Not better or worse, just different.

What's the point of the nice rumbling noise when it can't perform?
I know what you mean about the engine noise in the bimmer but it's not a performance noise unless it's a ///M car.

That's like saying that the IS isn't a sport sedan unless its an IS350.

The IS is marketed as "Intelligent Sport," not "Intelligent Luxury," hence the emphasis on performance. I for one thought the IS was too quiet...
I would dare say that the IS is one of the quietest vehicles in it's peformance and price categories. Javier
