2006 Midsize SUV : BMW X5

BMW joined the luxury sport utility vehicle ranks in the 2000 model year with its car-based X5, challenging midsize SUVs from Infiniti, Lexus and Mercedes-Benz. The 4.8is has a 355-horsepower, 4.8-liter V-8. Some previously optional items became standard in 2005. Automatic climate control became standard in the 3.0i, and the 4.4i added front and rear obstacle detection.

Xenon headlights, which are standard with V-8 power, are linked to the steering mechanism. Seating for five people features a high position for the driver and a 60/40-split, folding rear seat. The driver faces a familiar red-lit BMW dashboard. Leather upholstery is standard in the 4.4i and 4.8is. Options include heated rear seats, a heated steering wheel, a moon-roof and a DVD-based navigation system. Antilock brakes, stability control, side curtain-type airbags and side-impact airbags for the front seats are standard.

Side-impact airbags for the rear seats are optional. Performance is impressive, especially with the V-8, which delivers acceleration almost like a muscle car. The six-cylinder engine is energetic enough to satisfy most drivers. Automatic-transmission shifts are positive but curt. Shoppers who are seeking a comfortable ride may want to think twice about the Sport Package.
