Jaguar's smallest, least-expensive line consists of a sedan and wagon, both with standard all-wheel drive. X-Types have a 227-hp V6 engine and automatic transmission. ABS and an antiskid system are standard. So are front side airbags, curtain side airbags, and a driver knee airbag. X-Types come with leather-and-wood interior trim. A sunroof is standard instead of optional for 2007, and the wagon gains rear obstacle detection, which was optional. Heated front seats and a navigation system are optional.
