CHELSEA, MI – The Chrysler Pacifica cross/utility vehicle, slammed for being underpowered since its launch in 2003, gets a horsepower boost for '07 in the form of a new 4.0L SOHC V-6.

The new engine, which is standard equipment on all Pacificas except the base front-wheel-drive model, makes 255 hp – an increase of 5 hp over the 3.5L SOHC V-6 that has been the line's premium powerplant.

The 3.8L OHV V-6 becomes the standard engine on FWD base-model Pacificas.

The '07 horsepower hike also comes with a significant torque boost. The new V-6 will generate peak torque of 265 lb.-ft. (359 Nm), up from 250 lb.-ft. (339 Nm).

In addition, the 4.0L V-6 is mated to a new 6-speed automatic transmission that features variable line pressure.

The new 4.0L and the 3.8L holdover now also boast electronic throttle control. All-wheel-drive Pacificas have an electronically controlled clutch, as well.

Electronic stability control, which includes an all-speed traction control system and brake assist, becomes standard equipment as Chrysler Group continues its push to make the anti-rollover technology available on a wider array of vehicles.

A premium tire pressure monitoring system that offers specific information on each wheel is optional on the Pacifica Touring and standard on the Pacifica Limited.

Outside, the CUV gets a freshened appearance with hood, fender, headlamp, grille and front fascia revisions.

Dual chrome exhaust tips and a 4.0L badge are featured on models equipped with the new V-6.

And there are three new colors: Cognac Crystal Pearl Coat, Marine Blue Pearl Coat and Modern Blue Pearl Coat.

Inside, the rear-seat entertainment system features a larger 8-in. (20-cm) screen. And Chrysler offers its durable YES Essentials fabric upholstery that resists stain.
