Equipment
Heavy-duty (HD) features include full perimeter steel frame (there is debate as to whether the 9C1 Caprice uses a thicker frame than the civilian car; GM replacement frame part numbers for the civilian auto and the 9C1 Caprice are the same); oversized front and rear sway bars; full-size spare tire (in the case of the 4th generation 1994-96 Caprice Classic police car); high-output alternator; lifetime-rated green

Impala/Caprice 9C1 (B-platform)
Starting in 1986 the Caprice would replace the Impala for the retail, taxi, and police markets based on the third generation model which was launched in 1977. Like its civilian counterparts the car would get a facelift in 1987 and would remain the same until 1990. The Caprice 9C1 was available with either a V6 or V8 in this generation.
When the fourth generation 1991 model came, the former V6 was reintroduced for the 1992-93 9C6 taxi packages only and two new choices of V8 were offered for civilian, taxi, and police markets (the 5.0 V8 carried from the former generation and 5.7 V8) and featured a digital instrument cluster unlike its civilian version's analog interface, which would remain until 1993 when the LTZ version was introduced. When the 1993-96 model cars lost its rear

From 1994 to 1996, the detuned LT1 350 c.i. engine found on the fourth generation Chevrolet Corvette was a popular option on the 9C1 (the 4.3 V8 (RPO L99) being standard for police agencies looking for a more fuel efficient option), and standard equipment on other GM B/D-bodies at the time such as the; Chevrolet Impala SS, Buick Roadmaster, and the Cadillac Fleetwood. The 9C1 option, however, was not offered on any of these three models outside the Caprice.

Despite General Motors ending production of the fourth generation model Caprice 9C1 in 1996, many police departments across the nation kept them in service a lot longer than most other police vehicles from that time period, reasons being for lack of finding a good enough equivalent for replacement with decent fuel mileage for its large size, high horsepower, affordable sales pricing, and reliability. With General Motors leaving the police market in 1996, Ford's second generation

Dodge Charger police interceptor, serving as an indirect successor to the Caprice's muscle sedan image in the police market after a decade hiatus.
Caprice 9C1 (V-platform)
In 1999 the Caprice 9C1 name would be revived for the Middle East based on the
Holden Caprice
The Holden Caprice is a full-sized car which was produced by Holden in Australia from 1990 to October 2017. The similar Holden Statesman, which was also introduced in 1990 as a model below the Caprice, was discontinued in September 2010. Betwe ...

The same range of Holden Caprice almost got imported in North America right around the time that the Impala 9C1 based on the 8th generation Impala in FWD form was about to hit the police market.
Impala 9C1 (W-platform)
The modern day 9C1 police package was offered with the 2000 to 2005 8th generation Impala & 2006-2013 9th generation Impala/2014-2016 Impala Limited in FWD form. The 9th generation model would be the last

Mechanically, the 8th generation 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 8th generation 9C1 had a 0-60 time of 9.2 seconds and a top speed of 124 mph. Also, traction control was not available on the 9C1. 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. 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. This generation 9C1 was very popular with large inner-city departments such as the

V6 was now the standard and only powerplant, making 242 horsepower and 242 ft-lb of torque. It was mated to a 4T65-E HD transmission, which was carried over from the previous generation. 0-60 time was improved at 8.4 seconds, as was top speed at 139 mph. The steel wheels were also a carryover from the 8th generation Impala 9C1, as were the optional hubcaps. Traction control was once again unavailable on the 9C1 model. 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). 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. Additionally, the alternator was upgraded to a heavy duty 150 amp unit and the battery was upgraded to a larger 720cca unit. Furthermore, dual exhaust was now standard. For 2007, engine output was reduced to 233 hp and 240 ft-lbs of torque. 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. In 2008, the 9C1 became Flex Fuel capable in a move to compete with the

. 2008 models also saw the addition of an external trunk lock tumbler. Engine output was once again reduced in 2009 to 224 hp and 235 lb-ft of torque, and 9C1's now featured standard dual zone automatic climate control; which would be deleted after 2010.
The biggest updates to the 9th generation 9C1 came in 2012. The 3.9L V6 was dropped in favor of a much more powerful 3.6L
LFX V6. The new 3.6L V6 made 300 hp and 262 lb-ft of torque, and was mated to a six speed automatic transmission. 0-60 time was drastically improved at 7.2 seconds, and the 9C1 now had a top speed of 150 mph. For the first time,

was standard on the 9C1. The 2012 9C1 also received larger, 17 inch steel wheels with front brake ventilation via the fog light housings. The front fascia also received a minor refresh in line with the civilian model Impala, which brought SS style upper and lower front grilles to the 9C1. In addition, the rear fascia now had body color trim compared to the chrome on previous models. For 2014, GM released the 10th generation Impala. The 10th generation Impala did not offer a 9C1 version, but the 9th generation Impala 9C1 remained in production alongside the 10th generation Impala with "Limited" badging. In 2016, the 9th generation 9C1 was discontinued. This generation 9C1, like the 8th generation version, was also very popular with inner city police departments.
Caprice 9C1 (Caprice PPV)
![14 Chevrolet Caprice (14344068939)](https://upload.wikimedia.org/wikipedia/commons/a/ae/14_Chevrolet_Caprice_%2814344068939%29.jpg)
Replacing the Impala, the Caprice PPV (Police Patrol Vehicle) was manufactured by Holden in Australia, a left-hand drive version of the
Holden WM/WN Caprice exported to North America. Introduced for 2011, the PPV was offered exclusively for sale to law enforcement. The 9C1 package made its return, denoting patrol-ready versions, deleting the standard center console (for police computers), handbrake (for a footbrake), and vinyl flooring. In 2012, a 3.6L V6 was introduced as a standard engine, with the 6.0L V8 becoming an option (the first time since 1990 that a V6 was offered in a Caprice).
Following the introduction of the WN Caprice for 2014, all PPVs adopted the 9C1 package, with the update including a column-mounted transmission shifter. Coinciding with the closure of Australian manufacturing operations by General Motors after the 2017 model year, the Holden/Chevrolet Caprice ended production without a successor.
While not directly offered to sale outside of law enforcement, some initial examples of the Caprice PPV were purchased from General Motors as used cars by virtue of factory demonstrators being cycled out by the company, surplus unsold dealer inventory, and special one-time purchases (usually by fleet upfitters for equipment demonstration use).
Tahoe 9C1 (Tahoe PPV)
2021 brought a new Tahoe PPV which for the first time in the history of the Chevrolet Tahoe the 9C1 while all previous versions of the Tahoe PPV used the Z56 police package code. Features for the Tahoe 9C1 include rocker covers are borrowed from the
GM LT4 engine found in high performance Corvettes, Camaros and Cadillacs. Engine and transmission coolers are PPV specific.
