the bigger the opening grill,the better it will be interm of thermal efficiency. thats the diff between ss n preve at the lower bumper grill. but there will be a downside of it,air drag. well,of course there is the way to counter this by redesingning engine bay,engine design,engine placement and lower floor plan to channel the air smoothly to the rear end to reduce drag coefficient n lift,but it cost associate n normally sports car will use this.
but i like what ford done with active shutter idea. when in the city,the grill is open to help in thermal efficiency,and at speed,when velocity is enough to cool down the engine,the grill is closed to help reducing air drag. it is costly,but not as high as redesingning major part of the car. its brilliant indeed.
by the way,preve is being upgraded its safety pack without increasing the price,as what people complaint earlier,even the exact.
so let see how people responded by translating into sale as some of the complaint being fulfill. or it just talk the talk.
by the way,preve sale in thailand isnt encouraging due to thais policy,only 1.5l engine capacity and below for 1st buyer scheme. thats why ford intro 1.5l fiesta,n prtn only sell 1.3 saga. now,saga also not in good cndition when new policy that 1.2l car being given tax rebate causing price of saga is not cheaper anymore.
dunno whether prtn can ready the 1litre engine for gsc or 2nd option intergrate micro hybrid to gain some incentive. the latter will be more viable n i heard its nearly ready to the market.
Seems like Thailand purposely lowering the engine requirement just outside proton's reach...
