By birthright, Volvo is a master at producing vehicles that are great on snow-covered roads. That winter ability to trudge through inclement conditions is certainly part of the XC90’s DNA. For 2007, the SUV makes some significant alterations, including replacing the 2.5T engine with a new 3.2-liter, 24-valve inline 6 cylinder that produces 235 horsepower at 6200 rpm and 236 pounds-feet of torque at 3200 rpm as well as a new standard 6-speed automatic transmission. The transmission does its job without fuss, and the 6-cylinder provides 27 more horsepower than the engine it replaces. From a cosmetic viewpoint, the 2007 XC90 revises the grille, bumpers, taillights and showcases new side mirrors with integrated turn signals. The XC90 is a comfortable abode in all three seating rows. There is space for packages and groceries even when the third row seating spots are upright. And just a quick tug of an under seat pull strap sends a third row seat into a position that immediately reveals a flat, carpeted cargo floor. The Volvo XC90 features an array of standard fare, like airbag curtain head protection for all three seating rows, and 12 beverage holders. The heating/air conditioning system on the test vehicle had a slight hiccup when it failed to engage on a cold morning. (That same system snapped to life without any after-effects about 20 minutes after the “won’t work” glitch.) XC90 is also available with a V8, but the 6-cylinder version provides estimated mileage per gallon tallies of 16 city/22 highway. The MSRP of the all wheel drive SUV with 6-cylinder engine is $36,135.
