Big and luxurious, the Volvo S80 is Volvo's flagship sedan. It's fast, comfortable and roomy. It rides nice around town and it's powerful and tracks straight as an arrow at high speeds. It is without question a worthy competitor to comparably sized luxury sedans from Mercedes-Benz, BMW, Lexus, Acura, and Cadillac.The S80 offers a choice of engines, headlined by a 4.4-liter, 311-horsepower V8 built by Yamaha. The V8 sounds like a Corvette engine when it first starts up then settles to a smooth idle. It's smooth and creamy when cruising and very responsive. At high speeds the S80 V8 is quiet and smooth. Its performance (0-60 in 6.0 seconds, with a top speed electronically limited to 155 mph) stretches beyond what anyone can realistically use. But where the V8 really shines is in foul weather, where buyers will appreciate its standard all-wheel drive.Click here to read more
