It is a fair criticism. Technically though, it is an 8 way with the lumbar. Minimally, Mazda should've done a 10 way. It's only going to cost them more to have to re-engineer the seat if they do it for a refresh than if they did it from the start. Honestly, I don't think they will.
Here are the Mazda way to describe power seat from different models:
2016 Mazda6 Touring:
6-way power driver's seat
2016 Mazda6 Grand Touring:
8-way power-adjustable driver's seat with power lumbar adjustment and memory settings
2016.5 CX-5 Touring:
6-way power driver's seat with manual lumbar support
2016.5 CX-5 Grand Touring:
8-way power driver's seat with power adjustable lumbar support
2015 CX-9 Touring (and above):
8-way power-adjustable drivers seat with power-adjustable lumbar support
2015 CX-9 Grand Touring (and above):
Drivers power seat memory
2016 CX-9 Touring (and above):
8-way power driver's seat with power lumbar support
2016 CX-9 Grand Touring (and above):
Driver's seat memory
All
8-way power driver's seats, except 2016 CX-9's offer power operations on seat slide, height adjustment, front height adjustment of seat bottom, seat recline, and additional lumbar support adjustment. The
8-way power driver's seat in 2016 CX-9 which lacks front height adjustment of seat bottom, is exactly like
6-way power driver's seat found in CX-5 Touring and Mazda6 Touring but with additional power lumbar support! For 2016 CX-9, Mazda should say "
6-way power driver's seat with power lumbar support", or it's simply a case of false advertising.
No, it's very easy to have a true
8-way power driver's seat in new 2016 CX-9 simply by re-use all the parts and step-motor from previous-gen CX-9. Mazda simply is trying to save some cost. Penny wise, pound foolish!
