The top-line version of the X-Type has more standard equipment but a lower base price for 2004, while the base model loses some options. X-Type is Jaguar's lowest-priced car, and comes standard with all-wheel drive. The base 2.5 model uses a 2.5-liter V6 and manual transmission or optional 5-speed automatic. The uplevel 3.0 model comes with a 3.0-liter V6 and the automatic transmission; it offers the manual at no extra charge. Antilock 4-wheel disc brakes, leather-and-wood interior trim, front side airbags, and head-protecting curtain side airbags are standard on all X-Types. For '04, the 3.0 model's base price drops by nearly $3000 while it gains standard automatic headlights, sunroof, split folding rear seat, and wood/leather-wrapped steering wheel. Standard tire sizes are 16s for the 2.5, 17s for the 3.0. The Sport Package option, which is offered only on 3.0 models for '04, adds unique trim, sport suspension, and 18-inch wheels. An antiskid system is part of the Sport Package, but it can also be purchased as a stand-alone option, though now only on the 3.0. Other options exclusive to the 3.0 this year are xenon headlamps, navigation system, and rear-obstacle-warning system. Heated front seats are optional on both models. Dealer-installed voice activation for some audio, climate, and navigation functions is available.
