911 Cabriolet’s intelligent climate control automatically adjusts when roof opens

2020 Porsche 911 Cabriolet
The new 911 Cabriolet features an innovative climate control system that automatically adjusts to maintain individual temperatures while the top is opening.

During the launch of the all-new 911 Carrera, Porsche put on a runway-style fashion show highlighting each of the iconic model’s eight generations, along with numerous body styles and other permutations. While it would’ve been incorrect to dub any of these 911 successors as “retro”, being that the car was and still is an unbroken continuation of an ongoing model, some features, particularly its triangular “no-draft” vent windows, were only removed near the turn of the century with the onset of its water-cooled engine. Now Porsche is a leader in multi-zone automatic climate control system technology, particularly when it comes to the new 911 Cabriolet.

The new automatic climate control system will keep both upper body and lower extremities at the same temperature no matter the weather outside.

The German automaker recently developed an interior temperature sensor that can detect when the 911 Cabriolet’s retractable cloth top is opening, and then quickly make all the necessary adjustments so that front occupants won’t feel a change in cabin temperature. The advanced system incorporates 20 external and 20 internal sensors to continuously process 350-plus signals in half-second intervals, these including outlet, exterior, coolant temperatures, engine speeds, insolation, and vehicle speed. Once factoring in information from the soft-top, doors and seat positioning the system will slowly suppress a specific sensor while the convertible top is being opened, resulting ideal air temperature, air ventilation volume and air distribution to each occupant.

Now the 911 Cabriolet’s interior air temperature is as comfortable as its cabin overall.

In a press release Porsche goes so far to claim that “911 Cabriolet drivers are surrounded by a pleasant freshness” “… even in the searing summer heat of the city,” stating that its new intelligent climate control system is especially useful at low speeds.

The system is also effective when driving with the top down in cooler temperatures, eliminating the all too common “warm feet, cool head” scenario that anyone who’s driven al fresco in winter will be familiar with. Porsche’s intelligent climate control system disseminates more warm air through the centre vents, which gives the driver and front passenger “a cozy veil of heat without having the unpleasant sensation of air being blown in their faces,” continues Porsche.

“Blissfully warm hands on the steering wheel” is another bonus that allows the 911 Cabriolet’s driver to forgo warm winter gloves, claims Porsche, while both front occupants can stow their winter jackets in the trunk.

Watch how Porsche Adaptive Aerodynamics enhance 2020 911’s performance (video)

Who isn’t excited to see the new 2020 Porsche 911 Carrera on the road, let alone experience one first hand? While the latest sports car of sports cars might look to some like a mild makeover of a classic design, it’s a radical departure to those who live and breathe Porsche. 

Most applaud its fresh new styling, although some have criticized its backside when its attractively tapered deck lid transforms into a rather unorthodox rear wing, but no matter how much you like or dislike the car’s design, the method behind Porsche’s madness is hard to argue against. 

Less noticeable than the protruding rear wing are a set of active shutters that hide within the front corner grilles, which open above 70 km/h to minimize aerodynamic drag, while at 90 km/h the just noted rear spoiler gets raised into its most fuel efficient Eco position to once again reduce air resistance, although the aero system’s purpose changes from eco stewardship to maximum speed and grip at 170 km/h, when the front shutters open and the rear spoiler moves farther upward into its Performance position.

What’s more, as part of this Performance position the PASM (Porsche Active Suspension Management) sport chassis automatically drops down by 10 millimetres in order to improve its aero efficiency further, this sole feature adding four seconds per lap to the 911’s Nürburgring performance. 

The 911’s adaptive aero also adjusts for new Wet mode, plus the active rear spoiler will literally spring into action when emergency braking is needed by automatically canting farther upward into its “Air Brake” mode, adding downward pressure over the rear wheels for greater braking grip. 

How does it work? Like the previous 911, the new model’s sculpted body panels provide precise paths for oncoming air to flow overtop, underneath and around the entire car so as to minimize drag and maximize downforce, a balancing act that’s always challenging to perfect, but the new 911’s adaptive aerodynamics take it a step further by letting that air vent into the front corner intakes, pass through each radiator, and then flow around the front wheels like an air curtain in order to reduce turbulence.

This airflow continues along the 911’s doors before moving up and over the rear fenders into the engine vents mounted below the rear window, which feeds the 3.0-litre, twin-turbocharged horizontally opposed six-cylinder engine’s new air-to-air intercoolers, after which it gets directed down and out rear vents at each side of the back bumper.
