2007-2008 Chrysler Pacifica: A Very Brief Second Generation

With a new 4.0-liter single overhead cam (SOHC) aluminum V-6 engine mated to a new six-speed transmission that combines better gas mileage and acceleration, abundant standard safety features, stability control, YES Essentials® stain resistant, odor resistant, anti-static seat fabric, and lower price, the 2007 Chrysler Pacifica was a better deal than ever.

2007 Chrysler Pacifica models added standard safety features including all-row side curtain air bags, Electronic Stability Program (ESP), Electronic Throttle Control (ETC), traction control and an available ParkView™ rear back up camera (most children who die in traffic accidents are the victims of “backovers” so this is not really a frill). With a 5-star safety rating from the National Highway Traffic Safety Administration (NHTSA) for front- and side-impact, and four stars (the highest rating of vehicles tested in its class) for roll-over, Pacifica offers best-in-class safety without sacrificing style or performance.

With all-wheel drive and the utility of an SUV or minivan, but the fuel economy and safety of a passenger car, the 2007 Chrysler Pacifica had available heated first- and second-row leather seats, dual-zone temperature controls, Bluetooth™ compatible UConnect™ hands-free communication system and SIRIUS satellite radio.

Introduced originally in the spring of 2003, the Chrysler Pacifica appeals primarily to active families with older children at home. They want a vehicle with premium amenities that handles like a car, has sport utility-like capability, offers the roominess of a minivan and has an upscale appearance, for a price that makes sense. The typical Pacifica consumer is a married female between the ages of thirty-five and fifty who is a college graduate, has an average annual household income of $85,000 and has children over the age of 10 at home.

The original Pacifica was designed with a handsome, protective appearance. “The Chrysler Pacifica has always been an elegant, distinguished vehicle,” said Joe Dehner, Director Exterior Design. “The 2007 Pacifica adds more contemporary exterior cues and attributes in line with the Chrysler brand, while keeping the first-class interior design features that our customers love.”

Design cues that bring the “protector” appearance to life for the 2007 Pacifica include a broad-shouldered, wide stance and a sleek, solid exterior with a crisp, distinctive character line that begins at the front wheel opening and ramps up slowly toward the rear to emphasize the beltline. Chrysler-brand-inspired strakes / ribs / speed grooves on the hood, full-width chrome accent strip on the front fascia, a new grille with three horizontal bars and the distinctive Chrysler “winged badge” are new Chrysler hallmarks.

The Chrysler Pacifica features easy step-across entry and exit and chair-height seats that give passengers a sense of security and a commanding view of the road. Other new interior features for 2007 include a new two-tone instrument panel and door trim, revised instrument cluster graphics, and five- or six-passenger seating for a stylish, solid and secure ride.

2007 Chrysler Pacifica powertrain

The new 4.0-liter SOHC V-6 engine has a long stroke for improved low rpm torque, which provides quick and impressive engine response around town and offers the power consumers expect from a world-class V-6 engine. The 4.0-liter V-6 engine produces 255 hp @ 6000 rpm and 265 lb. ft. of torque @ 4200 rpm, which is 15 more lb. ft. of torque at peak power rpm, and as much as 35 lb. ft. more torque throughout the power curve than the previous 3.5-liter V-6 engine.

“The 2007 Pacifica’s new 4.0-liter, V-6 engine improves the torque curve in the low- to mid-range for more pep during acceleration from idle,” said Bob Lee, Vice President Powertrain Engineering. “Reductions in powertrain noise, vibration and harshness (NVH) also rank the new Pacifica among the best-in-class.”

When developing the 4.0-liter engine, Chrysler Group engineers focused on five primary Noise, Vibration and Harshness (NVH) metrics: engine vibration at the powertrain mounts, radiated noise, crank shaft torsionals, induction snorkel noise and sound quality. Attention to these metrics resulted in an improved engine design, which includes new main bearing diameters on the crankshaft, lower reciprocating mass piston and rod assemblies, an improved block and oil pan structure, reduced bearing clearance, low rumble intake manifold and an equal-length dual exhaust.

During development of the 4.0-liter engine for the 2007 Chrysler Pacifica, the following design changes were made:

Modified powertrain mount cradle assembly including new powertrain mounts and mount tuning

New, larger halfshafts

New accessory drive package

New electronically controlled clutch on all-wheel-drive models

Modified engine cooling system

New front bearings

New power transfer unit mounting structure and input shaft

New powertrain system calibration

New dual exhaust system with two mufflers and resonators

The 4.0-liter V-6 is a single overhead camshaft, 24-valve engine that utilizes a semi-permanent mold cast aluminum block with iron liners and cast aluminum cylinder heads.

“Overall powertrain NVH is improved with the new six-speed transmission because the added gear ratios within the transmission allow lower engine operating speeds for the same vehicle speed,” said Lee. “The new six-speed transmission also was designed to increase the peak launch torque capacity by 30 percent, allowing greater acceleration at start.”

The new six-speed automatic transmission is standard on all Pacifica models equipped with 4.0-liter V-6 engines. Building on the capability of Chrysler’s four-speed automatic transmission, the six-speed automatic transmission adds two new primary gear ratios and a secondary ratio for optimized passing performance at highway speeds. The gear ratios of the six-speed transmission enable the engine to work more efficiently at lower speeds providing a pleasant driving experience.

Part and process commonization allowed Chrysler Group engineers to develop the six-speed transmission in a shorter period of time and at a lower investment cost than previous transmissions without sacrificing durability or quality.

All wheel drive: fast and sophisticated

Steve-577 wrote:

I wrote to BorgWarner and asked if the new system sends torque to the rear wheels at a standing start before there is wheel spin at the front wheels, or after. What I find exciting about this system is that if you floor the gas

at a stoplight, you’ll get instant torque sent to the rear wheels BEFORE the front wheels spin or do the torque-steer dance we all dislike. And at highway speeds, the system disengages, allowing fuel mileage equal to FWD Pacificas.

He wrote: “The AWD system on the 2007 Pacifica all wheel drive uses information from the steering wheel, throttle, and wheel speeds, to determine the optimal system response to match driver desired vehicle behavior. It will update this system response many times per second. At low speed, sudden changes in amount of throttle applied can facilitate prompt system activation – in amounts determined by all of the underlying parameters. The amount of torque transferred is continuously variable, is of no set value and, if needed, can go to the maximum allowable torque specified by Chrysler.”

Pacifica safety features

Safety was paramount in the design of the Chrysler Pacifica. The National Highway Traffic Safety Administration (NHTSA) rated the Chrysler Pacifica 5-star for front- and side-impact, and four stars (the highest rating of vehicles tested in its class) for roll-over. The 2007 Chrysler Pacifica enhances the existing safety features by adding standard all-row side curtain air bags, standard ESP, traction control and brake assist.

A ParkSense rear back up system and ParkView rear back up camera also are available.

“Chrysler Pacifica is designed to give drivers and other occupants peace of mind while traveling,” said Lyons. “Loaded with safety and security features, the 2007 Chrysler Pacifica offers a wide stance, with suspension, steering and ride calibrated for optimal handling and stability.”

Meeting the new Pacifica

We met the Pacifica at a press event, along with two of its siblings. Outside, the Pacifica clearly resembles the new Aspen and Sebring, with their ribbed hoods (those are speed grooves, in case you were wondering; six concave, one convex), rounded-trapezoid grille, chrome, and similar front-end lines. Inside, they could hardly be more different, with interiors that appeared to have been designed by three different companies with very different cultures.

Cosmetically, the Pacifica remains much as it was, with a large black driver pod and a two-tone passenger pod, both featuring curves to personalize the dashboard to the occupants; there is light woodgrain on the wheel, with strips on the dash and door. Care was taken to provide an unobstructed 180 degree view from the driver, for a light, spacious feel.

The Pacifica is largely an enhancement of the current version, and it carries forward things that worked while making the appearance more distinctive. Pacifica will start at $25,000 and go on up to about $36,000; and frankly, it’s a bargain compared to many of its competitors.

Chrysler’s head of marketeing, Dave Rooney, noted that the 4 liter engine new to the Pacifica was designed to have more low-end torque and to provide a better off-the-line launch than most vehicles.


valiant67 noted that those with the Mopar Keyless Entry Module (part number 04883257, known as EVS II) can change their own alarm settings (proceed at your own risk):

1) Unplug the harnesses from the EVS module.

2) Remove the 4 phillips screws from the bottom of the housing.

3) Carefully separate the halves of the housing so as not to disturb the circuit boards.

You should see 4 switches, Sw1 – Sw 4.

Delayed (15 sec) trigger – Sw 4 Off
