Nuts and Bolts
Saab 9-7X models with a six-cylinder engine make 290 horsepower, while the V8 whips up 300 ponies. The big difference with the V8 is torque, of course, and for 2006, the bigger motor includes cylinder deactivation technology to save gas.
Both engines in the 2006 Saab 9-7X are sourced from GM’s family of Vortec motors. The all-aluminum 4.2-liter inline-six features dual overhead cams, variable cam phasing, and four valves per cylinder. With an output of 290 horsepower at 6,000 rpm and 277 lb.-ft. of torque at 3,600 rpm, this engine bests the six-cylinder units offered in Land Rover’s LR3, BMW’s X5, Volvo’s XC90, and VW’s Touareg. All aluminum construction, overhead valves (two per cylinder), and a block-mounted cam help the 5.3-liter V8 create 300 horsepower and 330 lb.-ft. of torque. Saab’s horsepower-to-displacement figure diminishes by comparison, however, when looking at competing models that displace 4.4 liters but yield greater power and comparable torque – like the BMW, Land Rover, and Volvo. And, while the Volkswagen Touareg’s V8 displaces even less cylinder volume at 4.2 liters, it still delivers 310 horsepower and 302 lb.-ft. of torque. The numbers also favor the competition when comparing transmissions. A four-speed automatic, a durable and well-respected Hydra-Matic unit from GM, backs both Saab engines. However, the other manufacturers offer more gear ratios and wider choices. All Land Rover LR3s use a six-speed automatic, BMW features both five- and six-speed autos plus a six-speed manual, Volvo uses a six-speed unit on the V8 model, and VW sports a six-speed, as well. Standard AWD is in line with the competition, as is the 9-7X’s fully independent suspension. With firm front and rear shock absorbers, a sturdy 36-mm front stabilizer bar, and stiff rear upper control arm bushings, the 2006 Saab 9-7X has been tuned to handle more like a European touring car than an American SUV. Rack-and-pinion steering directs the large 18-inch wheels, wrapped in P225/55R18 Dunlop tires designed specifically for the 9-7X. Vented brake rotors measure 12-inches up front and 12.8-inches in the rear, and ABS is standard.
