Honda has filed a patent software for an energetic diffuser that might deploy solely when wanted, preserving a automobile’s styling clear and uncluttered when it is not in use.

Rear diffusers are usually mounted in place, Honda notes in its patent software revealed by the USA Patent and Trademark Workplace (USPTO) on Feb. 6, however initially filed on Aug. 24, 2021. That creates a battle between the necessity to design an efficient diffuser and different concerns like styling, departure angles, and doubtlessly even authorities rules, in accordance with Honda.

The answer proposed within the patent software is a rear diffuser that might slide out from a automotive’s rear bumper utilizing an actuator. When deployed, the diffuser would generate an upward stream of air from beneath the automotive, balancing the downward stream of air spilling off the roof and serving to to scale back rear-end elevate, the appliance says. Not like a traditional diffuser, it will be stowed when not wanted, so vehicles would not have appendages protruding previous their rear bumpers.

Whereas some manufacturing vehicles have energetic rear spoilers, it appears automakers need to apply the same idea to different aerodynamic aids. Along with Honda’s rear diffuser patent, Ford has filed a patent software for deployable dive planes. However it’s unclear if both of those options will attain manufacturing.

Drawings within the patent software present the energetic rear diffuser on what appears like  previous-generation variations of the Honda Civic and Acura MDX, hinting that Honda is contemplating this function for abnormal sedans and SUVs. Because the automaker notes within the software, a deployable rear diffuser may assist improve efficiency in sportier variations of those autos whereas preserving practicality.

Sedan and SUV patrons will doubtless be much less tolerant of a automobile that has bother negotiating steep driveways as a result of low-hanging bodywork than patrons of purebred sports activities vehicles.

Honda does reportedly have an electrical sports activities automotive in growth as nicely, though such a automobile has been rumored for a while with no affirmation of manufacturing plans from the automaker. Honda will start launching a line of EVs developed in-house in 2026, beginning with a sedan-type automobile for North America.
