This innovation means that both turbochargers can be sized to operate with optimised efficiency. That means that the TTiD engine is not only powerful, it is also outstandingly economical. With an average fuel consumption of 50.4mpg, it is one of the most frugal performance cars on the road today. This makes for a smaller carbon footprint, with a combined CO2 output of only 149 g/km. Not only does this mean you can drive with a cleaner conscience, but for company car drivers it also means a lower tax bill.

 

Responsible Performance

Responsible performance is a phrase Saab uses to describe it's approach to designing safe, environmentally responsible performance cars. Our turbocharging expertise allows us to deliver impressive performance from small, lightweight turbocharged engines. Play the video below to hear Knut Simonsson, Saab's Global Brand Director, explain how the new TTiD engine embodies this philosophy.

Saab Turbo - Established 1977.

Saab didn't invent the turbo, they tamed it. Saab achieved this some 30 years ago when they developed a turbo engine with the reliability and durability required for everyday use. Since then Saab have continued to push the boundaries in turbo charging. Turbocharging allows increased power and fuel efficiency with a smaller engine.

 

The basic principle harnesses hot exhaust gases that are routed through a turbine causing the turbine wheel to rotate. The exhaust turbine wheel is joined to a compressor wheel which increases the airflow into the engine. More air means more fuel and more power in each cylinder. The result? You increase an engine's power with a minimal increase in its weight.

 

For years Saab was unusual in its extensive use of turbo technology. Now that the desire to reduce CO2 emissions without compromising performance is becoming more widespread, turbocharging is becoming more common. Imitation is, after all, the sincerest form of flattery.

 

Introducing TTiD - the newest example of Saab's turbocharged thinking

The development of TTiD arose from a classic engineering conundrum - how to produce a small economical diesel engine that can produce the power and responsiveness of a large petrol engine. To produce an engine that responds immediately to the throttle requires a small turbocharger. A small turbo can accelerate up to it's working speed of over 200,000 rpm almost immediately, giving a fast throttle response. However, to produce a high power output requires a much larger turbocharger that takes much longer to reach it's working speed, giving a much slower response to the throttle.

 

With a neat piece of lateral thinking, Saab has sidestepped the normal requirement for compromise. The new TTiD engine has not one but two turbochargers. The smaller unit operates at lower engine speeds and responds almost instantaneously, giving immediate acceleration when required. As the engine speed increases the smaller unit starts to reach it's operating limit. The engine's computerised control system automatically starts to transition to the larger turbocharger, until above 3,000rpm the larger unit takes over completely. The shift is invisible to the driver - all you notice is that you can have instant power when you need it.
