 The MC12 is a two @-@ door coupe with a <unk> top roof , although the detached roof cannot be stored in the car . The mid @-@ rear layout ( engine between the axles but behind the cabin ) keeps the centre of gravity in the middle of the car , which increases stability and improves the car 's cornering ability . The standing weight distribution is 41 % front and 59 % rear . At speed , however , the downforce provided by the rear spoiler affects this to the extent that at 200 kilometres per hour ( 125 mph ) the downforce is 34 % front and 66 % rear .
