Saw a “Rivian” pickup charging at a Walmart last week. I noticed that it did not have a front air dam, but did have front “half spads” covering the outside front third of the front tires. Underbody was very smooth. At the rear of the underside there was an upward slope creating a “diffuser” like Formula 1 car rears. Had what appeared to be a factory tonneau of the roll up slat design.
