Hirsch update

I have a particular Saab-related goal (ok, it’s one of many). One day I might even have the resources to achieve it and hopefully, if that day comes, the bits will actually be available here in Australia.

One of my Saab-related goals is to own a ‘Hirsched’ Saab one day. Probably a 9-5 like this magnificent piece of work owned by Jeff B in Melbourne.

If you’ve got a 2007 model 9-3 then there’s a new bit of Hirsching you can do right now – the 2007 Hirsch Leather Dashboard.

I’ll try and get a picture in higher resolution, but this enlargeable pic will give you an idea….


The new Hirsch Performance dashboard for the Saab 9-3 MY07 brings a completely new feeling to the car’s interior.

Just as its predecessor, the new dashboard is leather-covered with black leather of the highest quality. New for this year is the combination of black full grain leather with a new leather quality called carbon leather. Carbon leather is a natural leather, embossed with a carbon-fibre-structure, that allows a truly unique dashboard design. It can be treated and maintained just like normal leather.

For a very special touch for the Saab 9-3’s cockpit, the new carbon leather dashboard is an excellent choice.

The new leather dashboard is available for immediate delivery.

Unfortunately for you Brits et al, it’s available in LHD only. But still, what a magnificent looking piece of kit.

Some other thoughts from Hirsch to start the month:


Are your tyres slowing you down?

For maximum safety at high speeds, Saab vehicles have electronic top speed limiters that ensure that the tyres do not risk to become damaged due to overspeeding.

On the Saab 9-3, the top speed is not only limited to a maximum vehicle top speed, but there is also a second speed limiter which is set to match the maximum speed index on the currently installed tyres. Therefore, for cars with performance upgrades installed, it may for certain models be necessary to install tyres with a higher speed index. To benefit from the increased top speed, it is necessary to program the vehicle for the new tyre type using the Tech2.

Tyres rated H will limit the top speed to about 205km/h (as indicated on the speedometer), and tyres rated V will limit to about 230km/h.

The W-rated tyres standard on most Saab models theoretically limit at 260km/h, and with such tyres, the engine’s top speed limiter will regulate the top speed.


A note on fuel

Petrol and BioPower vehicles with performance upgrades from Hirsch Performance have been designed to benefit from petrol rated at 98 RON or E85 rated at 104RON.

They will, however run fine without any risk of engine damage on petrol rated at least at 91RON, thanks to the knock-detection and fuel adaptation technology in the vehicles’ ECU’s. However, especially in hot and high-altitude environments, the performance will be automatically reduced if the octane rating of the fuel used is insufficient. Besides performance, the fuel consumption will also increase slightly with lower octane fuel, due to the lower efficiency of the combustion. Hirsch Performance therefore recommends running performance upgraded cars with 98RON petrol, or 104RON E85 for BioPower cars, to achieve maximum performance and fuel efficiency.

For diesel vehicles, the efficiency of the combustion is not primarily limited by the fuel’s cetane rating but by other design factors, and there are therefore no significant performance advantages with higher-rated diesel.

For both petrol, E85 and diesel fuels, high quality clean fuel is vital for the durability and reliability of the engine, as well as its emission levels. A common problem with diesel fuel is the presence of soot-forming compounds that can risk blocking the particle filter. E85 imported from overseas can contain too high salt levels due to exposure to sea water spray, causing internal engine corrosion problems. Suspended particles and chemical impurities in petrol, E85 and diesel all tend to cause starting problems and rough running, as well as failure to meet emissions standards.

The quality of automotive fuel has improved immensely the last few years, but can still vary significantly between suppliers and regions. In temperate climates, it is also common to use different fuel qualities in winter and summer.

Hirsch Performance therefore recommends consistently using fresh new fuel from well-known high-quality suppliers to ensure a long engine life with the lowest possible exhaust emissions.
