It goes perfectly when fully loaded. I’ve just driven from Wollongong to Thredbo for a holiday with my mum & daughter, with half the back seat full of luggage & the boot full. It maintained the speed limit up hills & performed perfectly when overtaking, you only have to tap on the acceleration & it takes off, beats all the 10 or so 4 cylinder cars I’ve owned in the past - all of which would lose their speed on the hills when my foot was flat to the floor with the engine struggling - not the case with the CHR. Read my review & take it for a test drive with 3 or 4 of your friends or family
