Why the Saab 900 rocks - part 2 - ergonomics

Why the Saab 900 rocks (part 1) covered the interior. You can read that entry here.

If the early Saab 900 interiors were about the funk, it has to be said that the driver’s cockpit fascia, the dashboard, was all about the function.

I can remember my own first experience with the Saab 900. The thing that leapt out at me straight away was the dial in the HVAC controls with all the arrows on it. What the heck is that for?! was my immediate thought. Five minutes later it made perfect sense, and has ever since.

The Saab 900 dashboard is like that. At first it seems a little unfamiliar and more than a little strange. Spend some time there, especially with the car in motion, and you come to realise that it was developed by some very clever people.

So what are we talking about here? Let’s take a look.

Click.

The big thing about the Saab 900 dash is the ergonomic quality.

The dash was specifically designed to have all the operations that needed to be close by at the driver’s fingertips. Operating stalks for indicators, wipers, washers were all placed within reach of the driver’s fingers without the driver have to lift their hands off the steering wheel. The steering wheel itself was a masterpiece of comfort and control, too.

A short reach away on the door side of the steering wheel are the controls that only the driver should have access to. For example, the passenger shouldn’t be able to inadverdantly turn off the lights. Hence, they’re on the opposite side of the stering wheel. Same with the dimmer switch and the driver’s side mirror (also there because it’s the mirror for that side of the car).

A short reach away on the passenger side of the steering wheel are the controls for the audio system, the climate control system and other functions.

The dials for the climate system were all organised and set up to work so that the driver could operate them by touch without having to look at them. The fan was a small dial with discrete clicks between settings. The temperature dial worked in a smooth 180 degree arc (up for hot, down for cold - makes sense).

The confusing-until-you-got-used-to-it dial was the vent outlet dial, with a myriad of arrows pointing in all sorts of directions. Spend a few minutes to study it though, and it all makes perfect sense. The switch positions move logically from top to bottom. From the top, you can set it to the windscreen, then to the windscreen and feet vents, feet vents only, feet vents with cold air from the facial vents, the driver’s facial vents or all dash level (facial vents).

Note that those positions correspond with where the temperature setting would most likely be. When the temperature is set to hot (the dial points up) the most likely vent settings to be used are in the upper part of the selection range. It makes sense.

Many have noted the fact that the dials were also made so that they could be operated easily by a gloved hand in winter. It’s also notable that the Saab 900s heater is like a furnace!

Saab enthusiasts will also be familiar and very comfortable with Saab’s interior lighting. Green was chosen for its neutrality and the fact that it gave the closest effect to daylight conditions. The soft green lighting allows warning lights to stand out properly. It allows for the easiest reading of the matt black gauges with white lettering and orange needles - a setup that can be easily read with just a glance from the driver. Those gauges were deep set so as to avoid any glare on the 900’s superb, curved windscreen.

The Saab 900 didn’t start the key-in-between-the-seats thing. That was the Saab 99. The 900 carried on the tradition, though, and I’m glad they did as it’s another case of something that’s seemingly unusual making perfect sense.

The “between the seats” area is actually pretty important. Saab maintained the practice of having the handbrake there so that it could be operated by the passenger if necessary. Having the key there meant that the driver could fasten the seatbelt, insert the key, start the car and release the handbrake all in one easy set of operations.

My 1985 Saab 900 also has electric window switches in this area (not shown in the photo, above) and these are perfectly positioned so that the driver can just reach down and operate the front windows without having to look for them. They’re located right where your fingers fall if you position your arm in this area.

Saab have always made brilliant seats, and those in the 900 were a big part of this heritage. Saab made them to be very comfortable, and adjustable to the extent that over 90% of all drivers should be able to find an optimum driving position (not bad considering there were no steering wheel adjustments at that time). Seat heating kept the driver comfortable and alert.

The Saab 900’s interior layout was a masterclass in modern ergonmics and drew high praise from the motoring public of the time. Trends in materials and design have taken a lot away from this interior but several of the main elements still remain: the green lighting, the key position (bring back those central window switches!), the toggled air vents. Many other aspects of the 900s interior such as logical switch positioning have been taken up by others and are now the rule rather than the exception.

It’s still a truly extraordinary place to drive a car from. Supremely comfortable and very, very functional. I can only imagine what it must have been like, how revolutionary it must have been, 20 years or so ago.

As Eggs is given to saying: Vive la 900!
