Volvo's very popular luxury SUV is set to undergo an overhaul in a couple of years, but for 2007 the XC90 received just some minor cosmetic changes. They're barely noticeable on the exterior but a bit more evident on the interior (more wood accents, metal trim on gauges, and additional leather trim). Two more paint colors were also introduced. Although this is a luxury vehicle, safety is still the first thing that comes to mind with the Volvo name. As such, all XC90s come standard with Roll Stability Control and Dynamic Stability and Traction Control, as well as the Side-Impact Protection System and Rollover Protection System. Buyers of this SUV are willing to pay to get the best for their families, and they get it indeed. Fog lights and daytime running lights are standard equipment on all XC90s, as are mirror-mounted turn signals. These features help to improve safety, but that's not the only helpful technology that you'll find: look closely for a teardrop-shaped feature at the base of the side-mount mirrors. It is, of all things, a camera, a component of the new BLIS (Blind-spot Information System), which uses digital imaging to detect things in the car's blind spots. Upon detection it triggers a warning light to alert the driver. Fancy that! On any XC90 trim, you can opt for the impressive bi-xenon headlights, which anticipate curves in the road and swivel up to 15 degrees to shine around the bends. The base-model XC90 is the first Volvo released with the much-anticipated I-6 engine, which was developed to replace the 2.5-liter, 208-hp of previous years. The state-of-the-art I-6 provides 235-horsepower and 236 lb-ft of torque with no loss of fuel economy despite its larger size, thanks to keen technology. The two higher-priced trims come with a 4.4-liter V-8. Both engine types are transversely mounted, saving space to enhance the car's life-saving crumple zones. Fans of either transmission type will be satisfied, as the 6-speed Geartronic automatic transmission can also be shifted manually in situations when that is preferable (when towing, on curvy or snowy roads, or just to better feel what the engine can do). To fully load your XC90, go for the big-dollar options of the Navigation System and Dual-Screen Rear Seat Entertainment System. You can also opt for 18-inch wheels (or 19-inch on the V8 AWD Sport trim).
