it will be lighter than the ordinary CLK63 though...if the SLK was 45 kg lighter,this one will be around 100 lighter,i think.The power isnt relevant because this engine has a huge potential,even not supercharged,i think it can easily reach 100 bhp/litre...on the next generation...and judging by its driving dynamics,this car will be the best benz on the racetrack...thats enough for me
