My car did this when it was brand new; assumed it was cosmoline or similar anti-corrosion coating near the exhaust burning off. After a few months the car could be driven hard without any smell.

Seeing your car is about 5 years old, nothing is burning off the engine.
This is a perfectly normal, yet disgusting, feature of Toyota's catalytic converters. If you think ours are bad, take a ride in a 4runner with the rear window down. Anything past 3k RPM will fill the truck with a sulfer smell that will make your eyes water.
There are currently 2 4Runners in my family and they both do it...along with my 2007 IS350.

There is a potential for a catalytic converter to produce offensive sulfur smells, but it seems odd that you'd be able to notice it only while accelerating. After all, if the smell came from the cats, it should go out the exhaust and into the slipstream of your car. If you're smelling a rotten egg smell while moving, then you'd better get your exhaust checked out right away, because you may have a leak - and if you're huffing hydrogen sulfide (already not a friendly gas) then you're also breathing in carbon monoxide.

I get the rotten egg smell after driving alittle harsh or going uphill when the car downshifts and the rpm goes up to 5k... It's been like this since day one (Nov,2010) so it never caused any alarm for me.. Not to mention my previous IS (an 07 250awd) had the same issue..
Hmm.. Guess I have something to get checked when my car gets serviced in a few weeks..
