I think it does. If my Camry, built in 92, has a .34 drag coefficient, I don't see why, with the inward curving c-pillars, taller rear end, dual exhaust, lower ride height, underbody covers and spoilers, etc... All supposedly optimized in a wind tunnel, the Lexus couldn't see .26.

While they were at it, engineers further reduced wind noise and body NVH (noise, vibration and harshness) by testing the new car in the same wind tunnel used by Japan Railway for their bullet trains. Airflow around bumpers, fenders and mirrors was fine-tuned. Gains were made from the tiniest of things, such as adjusting the angle of the front grille bars, and adding small spoilers on suspension components beneath the body's sealed floorpan
