Car and Driver recently tested a G4 SE CVT. They were still extremely critical of the car, especially its acceleration which at 12.8 seconds was admittedly pitiful. Gas mileage wasn't great either at 33mpg average. However, they did concede Mitsubishi's work on the brakes and suspension provided noticeable measurable improvements. Stops from 70mph decreased from 184 ft in 2014 to 170 ft, which is flat out amazing for a cheap eco car. Roadholding increased from .74 to .78 which now beats the Versa sedan. So it sounds like putting 2017 brakes on the 14-15 model cars would be a worthwhile enhancement.
