Piston Slap: Feelin' Cross About Tall Cross Bars!
Steve writes:

Hello Sajeev,

I am a family man and typically have a family hauler in the stable — minivan, three-row crossover, and what-have-you. I always get the manufacturer’s trailer hitch and roof rack/crossbars.

So, I like the size of the new Traverse/Enclave, but have you seen the ridiculous crossbars? See photo above.

They must be 8 inches or more off the top of the car. I usually like the look of the roof rack on larger vehicles, but hate the new setup. I know, I could get aftermarket accessories, and probably would. I Googled around for a reason why they are so high off the top of the car but found nothing. My working theory is that by holding a cargo carrier, or other items on the roof high enough, the airflow from the windshield can pass underneath the cargo unobstructed, resulting in a smoother, more perfect, more aerodynamic vehicle-cargo union rather than running into an air-dam of cargo, effectively forcing airflow around the obstruction.

In any event, thought it was an interesting unanswered question and if we will start seeing this as the norm on new vehicles. Maybe it’s just me, but it looks pretty goofy to my eye. It also looks more dramatic in person, if you have seen them riding around.

How would the choice of 120V (using the 120V 'cord' charger that came with the vehicle) or 240V (using the charger on the wall) affect the following:a) Cost of the 'fill-up' -- i.e., is there a difference in efficiency of the energy delivery to the vehicle battery between 120V and 240V?b) Long-term life/health of the vehicle battery -- i.e., we know that fast charging stresses the battery more -- by analogy is 120V better than 240V?

  • SPPPP Speaking of soggy bottoms, those vinyl seats look very uninspiring. But the rest of the car looks pretty nice. I am not such a fan of combining a Nissan CVT with an over-stressed 3-cylinder, but I guess time will tell how that works out.
  • Lichtronamo Like most here, have a L2 Charger at home. Have only plugged into a publicly accessible charger 2x only to try it. We have an EV and ICE car in our garage, so we haven't driven the EV on a longer trip. I would like to try it on a road trip. I think the driving characteristics of an EV with somewhat longer stops along the way would be enjoyable.
