Driving Impressions

The standard Volvo XC90 and the T6 model have surprisingly different character. Our highest praise is reserved for the model with the base five-cylinder engine. Volvo's 2.5-liter five-cylinder engine produces 208 horsepower and 236 foot-pounds of torque at 4500 rpm. We found the five-cylinder's 208 horsepower to be plenty for the real world, and the 24 mpg EPA Highway rating is excellent for that much power in a vehicle as heavy as the XC90. But engines only produce power. Transmissions transmit the power to drive wheels, and the transmission in the five-cylinder XC90 is very sweet. It's a Geartronic five-speed automatic with a manual mode. We used manual shifting to test the engine's torque, which seems a little lacking at low rpm. However, it generates good acceleration when you floor it in automatic mode. We floored the gas at 1500 rpm in fifth gear and, in manual mode the XC90 accelerated ever so slowly. Then we tried automatic mode, and when we floored it at 1500 rpm the transmission downshifted all the way to third, the tach jumped and XC90 eagerly zoomed away. Obviously, the electronic transmission sensor didn't believe there was enough torque at 1500 rpm. Moral to the story: avoid manual mode for full acceleration, and trust the transmission to shift itself. And if you just want pulling power without full throttle, you can use the manual mode to downshift, if you need to. The T6 model also uses a Geartronic transmission, but it's only a four-speed. The T6 transmission must handle a lot more torque, and beefing up the five-speed to that level would leave no room in the engine compartment to fit it. As it is, the heavier four-speed transmission shifts more slowly and less smoothly than the 2.5's five-speed. Nor is the six-cylinder engine is as smooth or quiet as the five-cylinder. There was a distinct engine vibration between 45 and 50 mph in third gear, at about 2000 rpm. And although 268 horsepower and twin turbos sounds hot, we weren't impressed. With the four-speed, the engine sometimes feels like it's working hard, and the T6's lower mileage rating means about 60 fewer miles per tank. Regardless, we were impressed with how silky smooth the XC90 felt at 80 mph. Its chassis closely follows the design of the V70 wagon, but it's wider and the components are beefier. Our route included one long and remote leg of rough, narrow and twisty pavement, and, with two passengers, we fairly thrashed the five-cylinder XC90, and it eagerly ate up the road. Here, we used the big ventilated disc brakes hard, and manual mode in the transmission a lot, upshifting and downshifting as if it were a regular five-speed. A few times we flew into gullies that might have bottomed the nose of other SUVs, but the XC90 took that too. The XC90 didn't quite handle at the near sports-car level of a BMW X5 or Infiniti FX35. Its power rack-and-pinion steering is on the heavy side, and not as quick in the really tight stuff, but it feels reasonably tight in general, with decent feedback to let you know how the front tires are gripping. There's minimal body sway under hard cornering. We activated the DSTC electronic stability control a few times, and the system applied the brakes at one wheel without cutting the throttle, although we aren't sure if it was the gyroscopic roll sensor or traction sensors that triggered its operation. The XC90's ride is very good, maybe even unique: stiff at the wheels, but not in the cabin. It didn't exactly absorb the ridges and bumps, because you could feel the suspension working over them; but it didn't transfer any harshness to the arms or seat of the pants at all. Speed bumps in particular were interesting; it was as if the suspension challenged them and hammered back, protecting us from jouncing even when we hit them at 15 mph. The XC90's all-wheel-drive system is effective, too. It operates seamlessly, and the driver wi

Final Word

The 2004 Volvo XC90 offers a number of safety and utility features unavailable in most other luxury SUVs. The base XC90 2.5T uses a quiet, proven engine with good power and a smooth five-speed automatic. It delivers ample acceleration for all situations, good gas mileage and ultra-low emissions. The T6 is quicker, but more expensive and less fuel-efficient and comes with a four-speed automatic. Far more important, the XC90 is as good or better than its competitors in an area many people consider most important in the new generation of non-truck SUVs: hauling children around. The XC90 can make at least some claim to off-road (or at least dirt road) capability, and provides superior passenger/cargo flexibility with a ton of space at a luxury-class competitive price. Most SUV buyers should find that useful indeed.
