OF THE MYRIAD CHANGES BMW made to its new X5, the most notable one was dropping the 4.6-liter V8. That leaves the 2004 X5 with the 4.4-liter V8 and the 3.0-liter inline six. However, as we discovered, this isnt as disappointing as it seems.

For one thing, the 2004 4.4 V8 makes 315 hp at 5400 rpm. That surpasses the 03 4.4 by 25 hp while also providing better mileage, 16/22 mpg city/highway vs. the 03s 14/18 mpg. Secondly, that power lag (the departed 4.6 made 340 hp and 350 lb-ft of torque) will be resolved with a new 4.8-liter, 355-hp V8 model to arrive in spring.

Thats about all the information weve been able to get from BMW on the 4.8 performance model. For our test drive we made do with the 4.4i X5, and we enjoyed its smooth power. It blended well with BMWs trademark steering, brakes and fine handling (aided by a near 50/50 front/rear weight distribution). They felt excellent for an SUV. Oops, we mean SAV, as in Sports Activity Vehicle. BMW still calls it that because its so unique it demanded its own designation.

Somewhat unique is BMWs Valvetronic technology, which debuted on the 7 Series tech flagship. It provides most of the 25-hp boost in the X5s 4.4. Rather than using a typical throttle, Valvetronic varies valve lift from 0.3 mm (for idle) to 9.7 mm (for full power), avoiding the pumping losses from throttles and making the engine run smoother, BMW says. The intake manifold is also fully variable, instead of the traditional two-stage version that uses one path for low-to-medium speeds and one for high speed. And the engines variable valve timing includes the exhaust valves as well as the intake valves.

With those enhancements, the new 4.4i runs from 0 to 60 mph in 6.8 seconds, vs. the 03s 7.4 seconds. The gross vehicle weight rating is 6008 pounds and the towing capacity is 6000 pounds for both the 3.0- and 4.4-liter versions.

For 04, a six-speed manual replaces the 3.0is standard five-speed. The six-speed stick hurries the 225-hp, 214 lb-ft 3.0i to a 7.8-second 0-60 mph run, 0.3 second quicker than last year. A base 3.0i is $40,995, $11,200 less than a base 4.4i. A six-speed automatic is optional on the 3.0i and the only transmission available on the 4.4i.

Despite the X5s many changes, the 04 still looks quite similar to the first generation. All sheetmetal from the windshield forward is new. The BMW grille kidneys are higher and wider in the new model. The headlight clusters have a different shape to match those of other new Bimmers.

The roomy inside is comfortable, as both front occupants now get eight-way power seats standard. The pedals and switchgear are easy to operate, and new wood and leather colors are options. An optional retractable load floor rolls on ball-bearing rails. The interior volume is 97.6 cubic feet, and cargo volume is 54.4 cubic feet with the rear seat folded down.

As we reported in our Dec. 8 X3 cover story, the xDrive system also impressed us in the X5. xDrive analyzes road and driving conditions and uses a multi-disc clutch to deliver various amounts of torque to the front and rear wheels, maximizing traction and handling.

The all-independent suspension starts with double-pivot lower arms, struts, gas shocks, coil springs and an antiroll bar in front. In back is a four-link (partially aluminum) integral suspension with forward and rear upper lateral arms. The base 3.0i gets coil springs standard while the 4.4i goes with air springs (which are also optional on the 3.0i).

Our test drive included a brief off-road section, which the X5 handled okay, but we wouldnt want to take it on a long off-road trip. Even with hill descent control and traction and stability control, the X5 just feels more sporty-nimble than off-road rugged.

The sport package offers a tighter suspension, sportier wheels and tires (the 3.0is jump by an inch to 18 x 8.5 inches, and the 4.4is 18 x 8.5s grow to 19 x 9 front and 19 x 10 rear), sport seats and steering wheel, titanium-finish front bumper grille, side window trim, black gloss exhaust tips, and, last but not least, the 4.4is 130-mph maximum speed limiter is deleted, allowing a 149-mph top speed. That got us thinking: What max speed and acceleration times could the 4.8i version attain? If youre in the X5 market, weigh your situation to see if you should buy an 04 X5 now or if you should wait awhile.
