1.9 TiD |

| Latest diesel technology for Saab 9-3 Sport Sedan |
| |
| The Saab 9-3 Sport Sedan's widely-acclaimed, 'fun-to-drive' chassis dynamics are now complemented by the addition of a 'state of the art' 1.9TiD powertrain. The combination is expected to significantly raise Saab's penetration of Europe's growing diesel segment. Delivering more performance, more refinement, lower emissions and better fuel economy, this sophisticated powerplant endows the 9-3 Sport Sedan range with a compelling choice in the premium diesel segment that is as attractive and competitive as its gasoline offer. The new common rail, direct and multiple injection engine is configured for 150 bhp or 120 bhp. But, even more importantly, it offers a wide spread of strong pulling power, with 90% of the generous maximum torque available all the way from 1,750 to 3,250 rpm. It also raises the 'state of the art' by introducing a maintenance-free particulate filter that ensures compliance with Euro 4 emission standards, effective from 1 January 2006. Offered in Arc, Linear and Vector variants, it is fitted as standard with a six-speed manual gearbox, as well as the option of a six-speed automatic transmission for the 150 bhp version, a 'first' in the segment.s |

| Typical Saab turbo power |
| On the road, both 1.9TiD engines have a distinctly sporty character, further narrowing any perceptible difference between diesel and gasoline engine performance levels - except in the frequency of visits to the filling station. Saab turbo engines have always been characterized by an extremely strong and wide spread of torque, giving the kind of low and mid-range power that is needed in everyday driving. The 1.9TiD engine delivers just this kind of performance, demonstrated by the fact that 90% of maximum torque, an impressive 315 Nm for the 150 bhp engine and 280 Nm for the 120 bhp version, is generated between 1750 and 3250 rpm. Furthermore, the driving experience is enriched by a smoothness and refinement, together with a progressive torque build-up, that belies the presence of compression ignition. Engineers have helped to achieve this by calibrating the movement of the electronic throttle to deliver a response similar to Saab's gasoline engines. The process is optimized by a low-inertia, intercooled Garrett turbocharger, operating at 1.35 bar boost, which includes variable vane geometry (VNT) where the pitch of turbine blades is electronically adjusted for quick pick-up at low engine speeds. Low levels of NVH (noise, vibration and harshness) inside the car are due to the engine's advanced combustion technology as much as its careful chassis installation. This includes the adoption of an electro/hydraulic power steering system, for improved fuel consumption, and additional tuning of the front suspension and wheel angles. |

| Six-speed transmissions |
| The high level of driving satisfaction is reflected in the standard fitment of a close-ratio, six gear manual gearbox that encourages driver involvement and complements the 9-3's sporty handling characteristics. The optional six-speed Aisin AW automatic transmission for the 150 bhp engine is a 'first' for Saab and unique in this segment of the market. It is a smooth and adaptive unit, responsive to changes in engine load, road gradient or altitude, and quickly finds the 'right' gear without any irritating 'hunting'. It features lock-up in all forward ratios, except first. The driver can also switch to manual control by using a sequential floor shift or optional steering wheel mounted buttons. |

| Innovative Particulate Filter |
| The 1.9TiD powertrain includes the most advanced diesel particulate filter on the market, enabling Euro 4 emissions compliance, an essential requirement for many company car drivers. Unlike other particulate traps, it is maintenance-free and self-cleaning, requiring no additives or periodic replacement. Located in the exhaust system downstream of the close-coupled catalyst, the housing for the filter also includes a secondary oxidation catalyst to remove residual hydrocarbons (HC). The exhaust gases pass through this first, before entering the filter's ceramic core, made from a honeycomb of silicon carbide. This is perforated along its length by a matrix of microscopic channels, which collect the particulates as deposits from the exhaust. In order to clean the filter and to keep the exhaust flow as free as possible, these deposits are periodically burnt off by short pulses of over-fuelling. These briefly raise exhaust temperatures to the required level of 600º C. The process is automatically initiated when back pressure in the exhaust system reaches a certain level and is completely undetectable by the driver. This innovative solution has been made possible through the fuelling flexibility provided by the engine's multiple injection strategy. The self-cleaning process takes place whenever necessary, irrespective of throttle load or engine temperature. |
