GM caught patenting active aero for next Corvette

General Motors has patented advanced new active aerodynamics technology for its first mid-engined Chevrolet Corvette, which will become officially available in Australia via Holden in 2020.

The patents, discovered by CorvetteBlogger.com, appear to show the new aerodynamic aids fitted to the existing C7 Corvette, hinting the advanced aero could be introduced to the current model too.

More likely, the new aero tech has been designed to help boost performance for the all-new C8 Corvette, which will be sold alongside the C7 and may debut as soon as the 2019 Detroit motor show in January.

Already seen testing, the C8 is expected to come with significantly more power via GM's new twin-turbo 4.2-litre V8 or a mightier-still 5.5-litre biturbo V8.

Active aerodynamics have been deemed necessary to help cope with the Corvette's new-found performance, hence the three patent filings for a device that governs the US supercar's ducts, spoilers and side skirts.

Along with side air intakes, which are also previewed in the drawings, the active ducts appear to have been designed to direct cooling air to a powerful mid-mounted engine or exhaust system. Conveniently, at speed, the same ducts also help generate additional downforce.

Breathing via an air intake on the top and bottom of the car, enclosed pipes channel air from top to bottom and exit via a huge underbody diffuser.

Active side skirts are also included and they move to help direct air around the rear wheels, reducing drag. The larger the skirt area, the lower the drag, claim the drawings.

The final part of the Corvette's active aerodynamics puzzle is a large rear wing that adjusts its height and angle to increase downforce and drag. The spoiler acts differently at different speeds, steering angles and under braking, when it's thought it will act as an air brake.

As well as the wings and ducts, GM has also patented an active ride-height system that will also boost the Corvette's aero at speed, and may also include a front-lift system like those employed by Ferrari, Lamborghini and Porsche.
