No, you get more. They made changes to the steering and suspension and added the electric parking brake. They've also added more sound insulation to the bulkhead. They remapped post injection to ease dilution and increased the frequency of the regens to meet Euro 6. The centre screen also provides corrective actions for faults summarised in the dash warning panel. For instance if it says BSM malfunction in orange on the dash, going into the centre display now list checks - There is a fault with the BSM (blind spot monitoring or RCTA (rear cross traffic alert). Check rear bumper for obstructions such as leaves or snow. If problems persist, contact dealer.
The diesel was euro 6 on release, the petrol euro 5.
Latest car is definitely quieter, but as a result its gained weight.
Larger screen is a big improvement, although i personally don't see the nav as an improvement having used it now for some time.
The electronic handbrake does hold more effectively according to a practical caravan test last year where the cx-5 won its group due to the EHB addition.
I personally also prefer the front grill and interior on the new model, but i'm unsure about the new alloys on the sport.
Rear view camera day image is better, but on my car the night vision has gone backwards, dealer says its normal.
I also have an annoying brake squeal which the dealer again says is ok, but again the older version didn't squeal anything like this one which is embarrassing at times.
