dont worry its normal.. even with my non PE model.. after sometimes the smell will be lesser.. this burn smell will normally happen when you rev the car hard and going uphill where constantly revving like genting... so no big deal.. =)

the smell might frighten people..but no worries as its very normal due to most of the engine parts are still new..so i guess when the engine is super hot and parts are still tight it might have the smell due to temperature of high speed running that causes it to emit burn smell...it will slowly goes off after 30k-50k
