Daimler’s Freightliner trucks displayed an aerodynamic concept last month. This is the biggest use of aero parts (in a literal sense) I’ve ever seen.

I usually dont find much cool about trucks like this but to see functional aero in this context is pretty cool!

Rather than for racing use, this truck concept uses aero for fuel effiency during long hauls by lowering the aerodynamic drag. It also uses an electronic adjustable suspension that lowers at speed to get even better MPG.
