" Not that much , comparing same engine variants on both classes the weight difference between them is around 30 kg ~ 70 pounds in favour of the A class . They haven't listed the actual weight of the CLA 45 AMG , while we have 1.555 kg for the A45. I suspect somewhere slight under 1.600 kg / 3.500 pounds for the CLA 45 which should go on the rear axle. Well , we just have to wait and see then, but sounds like a great car if it does 12.4 on the 1/4 mile out of the box. "
