Curious if retractable rear diffuser (to reduce aero drag) will make it to production.  I can’t make out details from previous picture, but Mercedes used similar diffuser to achieve a Cd of only 0.17 with EQXX prototype, and now using on CLA to reduce Cd to only 0.21.  

Thanks, but no need.  I can still do it from memory.  All I need is a calculator and to remember EPA estimates that burning one gallon of gasoline produces 8,887 grams of CO2.  Helps to remember basic conversions as well.   For example, in above data I posted previously, simple math shows ICE and HEV fuel economy dropped from approximately 40 rated MPG to 33 actual real-world MPG.  That seems reasonable to me.  However, the 35 grams per kilometer rating for PHEV is completely unrealistic unless the vehicle operated mostly in EV mode and electricity was generated carbon free, which on average it is not.    

I like it. Let’s not forget that Toyota took the Prius and made it a good looking sedan too. If you squint a bit, the Corolla looks a bit like the Prius but with sharper edges.

If you get bored, the calculations are here: https://www.epa.gov/energy/greenhouse-gas-equivalencies-calculator-calculations-and-references 8.89 × 10-3 metric tons CO2/gallon gasoline × 10,917 VMT car/truck average × 1/22.8 miles per gallon car/truck average × 1 CO2, CH4, and N2O/0.994 CO2 = 4.29 metric tons CO2e/vehicle /year   The other way to look at it is that for every kwH being produced by a power plant, its going to multiple things not just powering a car...then multiple the number above for every single vehicle being operated at that time, which adds up very quicky   TLDR-Powerplants overall produce less CO2 then thousands/millions of cars operating at the same time.     

Regardless of how it’s classified, isn’t what is important the end result?  If an owner took 100 trips to local destinations averaging 10 miles round trip each, and then takes 1 round trip of 3,000 miles, how much CO2 savings does PHEV or EREV actually accomplish?   I’ve seen reports that focus more on number of trips to represent usage patterns rather than driven miles, which is a closer indicator of how much gas is burned.  Your point that one long trip skews data is valid.  Obviously analyzing actual cumulative fuel consumption data yields much better and useful information.   Even that doesn’t address that when operating in EV mode the vehicle still produces significant amounts of CO2, just not at tailpipe, but rather at electricity generation power plant.  The corrected numbers would be much worse because very few BEVs or PHEVs are charged with zero emissions electricity.

This Telluride looks better, but I'm the opposite on a lot of the latest Hyundai/Kia products - they're going with that origami 80s futuristic look that looks cool for 5 minutes and then just looks old/weird.  Their latest wheel designs are by FAR the ugliest in the industry too.

It would be interesting to know how my data is interpreted when I do a long road trip (e.g. traveling to our snowbird location in Florida).  I suspect it categorizes me as an owner that rarely plugs in my PHEV.

The PHEV data was based on computer downloads from cars in for service.  

I said 2025+ meaning future models too.  The fact that warranty costs are down significantly plus all of the recent problems identified very quickly only affecting a few thousand units say they’re headed in the right direction.  Of course it doesn’t guarantee future success but this is how process changes work.   That is not negated by finding new problems that occurred before the process changes were put in.
