9C1 (Chevrolet Police package)
9C1 is a code used by Chevrolet, in reference to a vehicle intended for use as a police car. Considered a fleet vehicle by General Motors, the 9C1 package is considered a Special Equipment Options (SEO) code, as opposed to a Regular Production Order (RPO) code. Both groups of options are found on the production code sticker (which on most modern GM vehicles is located in the glove box).
Specific modifications and upgrades of each version of the 9C1 option package differs by vehicle platform, though it centers around increased durability and performance. Other parts of the 9C1 package are designed to allow for the fitment of required emergency lighting and equipment.
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 silicone coolant hoses; four-wheel disc brakes; HD steel wheels and speed-rated tires; quick-ratio power steering and transmission and power steering oil coolers; certified digital speedometer; stiffer body mounts and more of them; true dual exhaust; anti-stab steel plates in the front seat backs; performance 3.08 final drive ratio (3.23 w/std.); 200 hp/245 ft·lbf L99 V8 4.3 L (265 cid) SFI engine); and extra wiring for the emergency equipment.
Since the 1970s, Chevrolet has offered factory-produced police car variants of the Chevrolet Nova, Chevrolet Malibu, Chevrolet Celebrity, Chevrolet Impala, Chevrolet Caprice, and Chevrolet Lumina.
The Nova 9C1 was offered to police agencies between 1975 & 1979 originally starting off as a prototype for the Los Angeles County Sheriff's Department in 1974. The Nova 9C1 was available to police agencies as either a 2-door coupe or 4 door sedan with an array of different options.
A 9C1-equipped Malibu with an LM1 350 Z-28 Camaro V8 engine driven by E. Pierce Marshall placed 13th of 47 in the 1979 Cannonball Baker Sea-To-Shining-Sea Memorial Trophy Dash, better known as the Cannonball Run.
Impala/Caprice 9C1 (B-platform)
Starting in 1986 the Caprice would replace Impala for the retail, taxi, & 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 & would remain the same until 1990. The Caprice 9C1 was available with either a V6 or V8 in this generation.
When the 1991 models came the V6 was dropped & only 2 choices of V8 were offered which would remain until 1993. When the car lost its closed rear wheel well design with all models this also affected the 9C1 too. The 1991-1992 4th generation Caprice wasn't popular due to the closed rear well design.
From 1994 to 1996, the 260 hp (190 kW) LT1 350 c.i. engine was a popular option on the 9C1 (the 4.3 V8 (RPO L99) being standard), and standard equipment on the Impala SS, Buick Roadmaster and the Cadillac Fleetwood. The 9C1 option, however was not offered on any of these three models.
In 1999 the Caprice 9C1 name would be revived for the Middle East based on the Holden Caprice from the WH Statesman/Caprice range for the 2000 model year. This same police package was used in the VT Commodore range at the time which was also sold in the Middle Eastern market as the Lumina. 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.
The Caprice 9C1 returned in 2011 in the form of the 2011–2017 Caprice PPV (based on the WM/WN Caprice range manufactured in Australia in left-hand drive) for the North American market. This generation would mark the return of the V6 since the third generation Caprice & is standard since the 2012 model year and a v8 which was standard in 2011 & has become optional since 2012. This vehicle is not offered for direct sale in the United States by General Motors except to Law Enforcement accounts. Some individuals have purchased these vehicles, however, as used cars by virtue of factory demonstrators being cycled out by GM, surplus unsold dealer inventory, and special one-time purchases (usually by fleet upfitters for equipment demonstration use).
Impala 9C1 (W-platform)
The modern day 9C1 police package has been offered with the 2000-2005 8th generation Impala & 2006-2013 9th generation Impala/2014-2016 Impala Limited in FWD form.
Holden Commodore 9C1
The 9C1 name was also offered with the Holden Commodore starting with the 1997-2000 Holden Commodore (VT) & ending with the 2004-2006 Holden Commodore (VZ) by GM's Australian affiliate Holden. The VZ Commodore 9C1 (or VZ Commodore Police Pack) was available to all police organisations in Australia, New Zealand and several in the Middle East as the Lumina 9C1. It was based on the Commodore Executive and added various specification upgrades to cater to the needs of police. Most 9C1s were delivered in white, but were also offered in other colours, normally used as unmarked vehicles.
The 9C3 feature package is a variant based on the 9C1 package, and has been historically offered alongside 9C1. The largest difference is the interior design differences 9C3 is intended for undercover or supervisor use, and typically features a more consumer-oriented interior starting with the 8th generation Impala in 2001 all the way to the 9th generation Impala Limited. This police package code was originally offered with the Chevrolet Lumina's 1st generation model starting in 1992 & again with the 2nd generation in 1995 as the mid size front wheel drive alternative to the rear wheel drive Caprice sold between 1991 & 1996.
The current-generation Caprice PPV was offered with a 9C3 package in the 2011, 2012, and 2013 model years it used the standard interior same as the Middle Eastern Caprice base model LS which both were sourced from the VE II Commodore Omega, instead of the custom gear-shifter and center column/armrest that the 9C1 featured.
