9-5 Wagon Performance



SAAB 9-5 WAGON'S TURBOCHARGED POWERPLANTS PROVIDE SPIRITED, EFFICIENT PERFORMANCE

NORCROSS, Ga. - The Saab 9-5 Wagon engine range features two light pressure turbocharged engines, both benefiting from more than twenty years of Saab experience in the field of automotive turbocharging. Due to these innovative turbocharged engines, the spacious 9-5 Wagon drives more like a premium sports sedan than a cargo-carrying wagon.

Saab Ecopower Turbo Engines
As with the Saab 9-5 Sedan, two engine variants are available in the Saab 9-5 Wagon - a 3.0L V-6 asymmetrically turbocharged engine (only available as standard equipment on SE models) and a 2.3L four-cylinder light pressure turbocharged engine. Both engines are members of the Saab Ecopower family - which means they are designed to provide a unique combination of responsive performance, low exhaust emissions and high fuel efficiency. One of the most noticeable effects of Ecopower technology is the high torque output achieved at low and mid range engine speeds - providing quick acceleration and strong off-the-line response.

The 3.0L V-6 generates 200 hp at 5,000 rpm and strong maximum torque of 229 lb.-ft. from 2,500 rpm to 4,000 rpm. The 2.3L four produces 170 hp at 5,500 rpm and maximum torque of 207 lb.-ft. from just 1,800 rpm all the way up to 3,500 rpm. This broad maximum torque range provides power on-demand for real world driving needs.

The 3.0L V-6 is matched with a standard 4-speed automatic transmission, featuring "Sport," "Winter" and "Touring" shift modes. The 2.3L four-cylinder Saab 9-5 Wagon comes standard with Saab's 5-speed manual transmission. The 4-speed automatic is available as an option. Saab's Traction Control System (TCS) is standard equipment on all 9-5 Wagons. TCS is an "all-speed" system that modulates ABS braking and electronic throttle to optimize traction at the front drive wheels for enhanced control in inclement weather conditions.

Saab V-6 Engine Features Asymmetric Turbocharging
The Saab 9-5 was the first car in the world to be equipped with an asymmetric turbocharging system. This engine concept uses one turbocharger on the left, or front, cylinder bank, driven by exhaust gases from only those three cylinders. The single highly-responsive Garrett GT17 turbocharger delivers compressed air to all six cylinders in both cylinder banks. Combined with a boost pressure that reaches only 3.6 psi (0.25 bar), this technology allows a patented boost control system that eliminates the need for a wastegate.

The advanced 24-valve 3.0L turbo V-6 engine uses a narrow angle of 54 degrees between the cylinder banks. The engine's strong maximum torque of 229 lb.-ft. at only 2,500 rpm, available all the way up to 4,000 rpm, provides useful performance to reduce passing times and avoid potentially hazardous situations. The high torque also allows longer gearing, which improves fuel economy and reduces engine noise at speed.

Saab's 2.3L Ecopower Engine
The Saab 9-5 Wagon's 2.3L light pressure turbocharged engine uses relatively low boost pressure (maximum boost of about 8.0 psi or 0.55 bar) to deliver boost quickly, providing higher torque at low engine speeds. Extra power is put to use only when it is actually needed, providing a comfortable, satisfying driving experience, with responsive performance, low fuel consumption and low exhaust emissions. Strong low-end torque also contributes towards safer passing and more relaxed driving, without needing to frequently rev the engine to high rpm.

The 2.3-liter engine has been programmed to develop optimum power with a very flat and broad torque curve. The power curve peaks at 5,500 rpm, while the torque curve is actually a torque plateau - a completely straight line from 1,800 to 3,500 rpm. In fact, over 70 percent of the peak torque value is developed from just above the idling speed to the electronically-governed redline at 6,000 rpm.

Saab Trionic 7 Engine Management System Both engines feature the latest version of Saab's Trionic engine management system - Trionic 7. A highly sophisticated system, Trionic 7 utilizes a 32-bit microprocessor capable of two million calculations per second to control Saab's direct ignition, fuel injection, turbo boost pressure and the electronic "drive-by-wire" throttle to enhance engine response and eliminate turbo lag. It allows both engines to provide low emission levels, high fuel efficiency and adaptable power and torque levels, for flexible and responsive driving characteristics.
