2005 Volvo XC90 in Hallandale

The Volvo XC90's fine quality, loads of innovation and safety equipment, and Scandinavian good looks have made it North America's best-selling European sport-utility. But with a V-8 engine now de rigueur among premium SUVs, the XC90's underwhelming five- and six-cylinder engines weren't going to cut it for long. Trouble was, the XC90's P2 platform wasn't designed to accommodate a longitudinally mounted V-8, and corporate parent Ford had not a single eight-cylinder engine compact enough for transverse application. A lengthy search led Volvo to Yamaha, which, as you may recall, created the trim, 3.4-liter V-8 in the second-generation Ford Taurus SHO. Although very similar, the XC90's 60-degree V-8 shares no parts with the SHO engine; it has more in common, in fact, with Yamaha's current range of V-6 outboard boat motors. Displacing 4.4 liters and featuring continuously variable intake- and exhaust-valve timing, the all-aluminum V-8 produces 311 hp at 5850 rpm and 325 lb-ft of torque at 3900 rpm. Built in Japan and shipped complete to Sweden, the engine is also the only gasoline V-8 to meet ULEV II emissions standards.

The Yamaha's quiet, creamy demeanor better recalls a Lexus V-8 than one from BMW or Infiniti.... Read full article
