2007 models also saw the addition of GM’s Active Fuel Management as standard equipment, which shuts off a bank of cylinders to preserve fuel. For 2007, engine output was reduced to 233 hp and 240 ft-lbs of torque. Furthermore, dual exhaust was now standard. Additionally, the alternator was upgraded to a heavy duty 150 amp unit and the battery was upgraded to a larger 720cca unit. Like the 8th generation 9C1, the 9th generation version had auxiliary coolers for the engine oil, power steering, and transmission, heavy-duty police calibrated ABS brakes, a heavy duty 4 wheel independent suspension, and a heavy duty cooling system this time based on the cooling system from the 9th generation Impala SS. The new 9th generation Impala 9C1 featured dual power seats, automatic headlights, cruise control, keyless entry, tire pressure monitor, digital speedometer readout, reinforced front seat frames with a center-mounted crush box, and side curtain airbags (which could also be deleted as an option). Traction control was once again unavailable on the 9C1 model. The steel wheels were also a carryover from the 8th generation Impala 9C1, as were the optional hubcaps. 0-60 time was improved at 8.4 seconds, as was top speed at 139 mph. It was mated to a 4T65-E HD transmission, which was carried over from the previous generation. A 3.9L GM High Value Engine V6 was now the standard and only powerplant, making 242 horsepower and 242 ft-lb of torque. For the 9th generation, the 9C1 was based on the LS trim. The 9C1 was also included in the redesign, and it received significant upgrades over the previous generation. The Chevrolet Impala was re-designed for the 2006 model year, once again riding on the W-body platform. This generation 9C1 was very popular with large inner-city departments such as the NYPD. The 9C1 featured a standard AM/FM radio, standard dual zone climate control, a standard driver side torso airbag (2005), and lockout protection which prevents the driver from locking the keys in the ignition in the event someone tries to lock the doors. The interior featured several features not available on civilian Impalas including stab-proof front seatbacks, heavy duty front seats, a 100 amp auxiliary power point in the trunk, and “Surveillance Mode” which was a button that disabled all interior lights to allow officers to hide themselves better. Also, traction control was not available on the 9C1. The Impala 9C1 had a 0-60 time of 9.2 seconds and a top speed of 124 mph. Mechanically, the Impala 9C1 featured many upgrades over the standard Impala including auxiliary oil coolers for the engine oil, power steering, and transmission, a heavy duty radiator with heavy duty fans and extended life coolant, heavy duty front struts, heavy duty shock absorbers, police calibrated brakes, heavy duty front brake pads, and a 125 amp alternator. The 3.8L V6 was mated to a heavy duty four-speed 4T65-E HD transmission. The 2000-2005 Impala was powered by the 3.8L Buick V6 engine that made 200 horsepower and 200 lb-ft of torque. Sales for the Impala 9C1 and 9C3 were strong with law enforcement and they were especially popular with large city fleets such as the NYPD and Philadelphia Police Department. The 9C3 was comparably equipped to the 9C1, but the ability to add other convenience options and more paint and interior choices set the 9C3 apart. This enabled the driver to turn off all lights in the vehicle and “hide” something not allowed with the civilian models, as automatic headlights were standard. Another addition was the “SURV MODE” switch that replaced the fog light switch found on the LS. It was only available in a few basic colors. It also offered preparation for a criminal cage to be installed between the front and rear seats. It also came with the option for a rear vinyl bench seat and front cloth bucket or bench seats, both cloth front and rear seats, or vinyl front and rear seats. The 9C1 was a base model with a stronger suspension and the 3.8 liter (231 cu in) V6 engine. Available only to law enforcement agencies, fire departments, and EMS agencies, it has had much more success than its predecessor, the Lumina 9C3. Unlike the earlier Impalas built on a B-body, this one was front-wheel drive.Ĭhevrolet also released a 9C1 Police Package version of the car in 2000, as well as the 9C3 Undercover Police Package first released in 2001. Based on the Lumina’s W-body platform, it was built at Oshawa Car Assembly in Oshawa, Ontario, Canada. With a wheelbase three inches longer (though an inch shorter overall) than the Mid-size Lumina, the new Chevy Impala was categorized as full-size by but mid-size by Consumer Guide Automotive. Chevrolet revived the Impala name for the 2000 model year.
