The chart is just the hard line CO2 requirements and their set dates 2015, 2018 and 2022. FCA just places dots on the various models it produces or will produce to meet these dates. There is no scale in between the CO2 hard dates do I read the diesel wrangler as sometime before 2022.Take a closer look at the chart in post #1, some folks are reading it wrong.
The new generation Land Rover Discovery has a TDV6 diesel for NAS coming this year 2017. It's looking very appealing.
