Don't forget the aircon isn't just weight... it's also sapping your engine of a few ponies. Most likely why Cups generally make closer to standard power on a RR.
As for me..... I love the CC. lol.
Nearly all the Cups sold after Climate OCntrol was made an option were fitted with it. It was probably an indicator to Renault that people actually wanted a 'hardcore' car but more in name than reality............. maybe the reasoning behind the weak 'Cup' offerings ever since.
172 Cup or not at all. Unless you're a pikey and just like things cheap of course, but no -ones going to admit to that
