Sorry I know I am in the category of silly OLD fool BUT when will they stop these stupid gimmicks. Looking at the video, how much difference does it really make to the aerodynamics.
I have just watched a video from my Brother in Canada about Russian lorries and drivers coping with what in the UK would bring the whole country to a standstill. Freezing rivers and mud to several feet deep and they just plough through it.
Now like Russia, Canada they probably need rad shutters to keep the cold off the rad. Many forum readers would not know of the thermo syphon system which was the norm in cars of yesteryear and even in 1962 when the thermostat was fitted as norm, the bottom of the rad was known to freeze due to the cold. BUT the UK and even Spain in the mountains surely a shutter on the rad is unnecessary.
Classic bit of useless gimmickry. Yesterday, going down a hill I was braking. Up pops in front of me on the little screen. Braking applied engine power reduced!!!!!!!!!!!!!!!!!!!! Unless you are a Rally or Racing car driver most normal people remove their foot from the accelerator to apply braking.
