Unique Cars for today and Beyond

Though it's only been a year since Jaguar introduced its XF midsize sedan,
changes come for 2010 in the form of new drivetrains, a new trim level and a
performance version, the XFR. Competing models in size and/or price include the
Audi A6, BMW 5 Series, Cadillac STS, Lexus GS and Mercedes-Benz E-Class. The XFR
squares off against the souped-up versions of those cars, such as the S6, M5 and
STS-V.
