The day after Ford announced that the 2020 Ford Police Interceptor Utility was now the fastest pursuit-rated police car in North America, social media lit up with comments about how, “they still can’t catch my BMW/Corvette/Ferrari/Tesla/super-turbocharged Civic … etc.”
These types of comments all miss the point. Top speed may be one of the least important factors in choosing a modern police vehicle. Actual pursuits are only a small part of their purpose. They also have to be a comfortable and safe workplace for one or two officers for up to 12 hours at a time.
On the other hand, the new Ford SUV ties the 2020 Dodge Charger 5.7-litre Hemi for top speed at 150 miles per hour (mph), and bests its 0-to-60 time of 5.81 seconds by 0.38 seconds. That’s close. That’s fast.
Model year 2020 is indeed a year of both firsts and lasts for Ford: the first pursuit-rated SUV hybrid; the first year a combined gas/electric hybrid drivetrain is standard in both the Ford Sedan and the Ford Utility; the last of the Ford sedans.
In 2019, Ford stopped selling the Ford Taurus, which was the base for the Ford Police Interceptor Sedan. Now called the Police Responder Hybrid, the sedan continues for 2020 but only in a front-wheel-drive, 188-horsepower hybrid version. A version of the Ford Taurus is still being built by a joint venture between Ford and Chongqing Changan Automobile of China, and the Chinese Taurus just received a body redesign and a new 2.0-litre hybrid engine, so there is some speculation that Ford may import a version from China for the police market in North America.
Or perhaps the sedan may just disappear after 2020. In the United States, police SUVs have been out-selling sedans by almost five to one in recent years. In 2018 for example, Ford sold just over 7000 police sedans and almost 34,000 police SUVs in the U.S. They are still popular in urban areas, but with the only choice in Ford being a relatively slow front-wheel-drive sedan, the only option for police agencies in North America may be Dodge.
Dodge has already announced (and tested) two new sedan models for 2021: an all-wheel-drive (AWD) version of the 3.6-litre V6 Charger Pursuit and a rear-wheel-drive (RWD) version of the 5.7-litre V8 Charger. Both versions of the Dodge Charger will now be available in either RWD or AWD for 2021.
Jumping on the SUV bandwagon, Dodge also sells two pursuit-rated versions of its AWD Durango.
While all the following vehicles are advertised as “pursuit-rated,” there is no specific definition of the term, but Michigan State Police (MSP) and Los Angeles County Sheriff’s Department document and test every police model offered for sale in North America, and both agree that police category vehicles should be designed for the full spectrum of police work, including pursuits.
Traditionally, a pursuit capable vehicle must be able to reach 60 mph in nine seconds, 100 MPH in 24.6 seconds, complete all 32 laps of the dynamic testing without major component failure, and maintain an average deceleration rate of 25.79 feet/sec2 while performing 20 threshold braking stops from 60 mph. As always, it will be up to the individual agencies to determine if a particular vehicle is suitable for their mission.
Also, as far as pursuing and catching plug-in electrics like a Tesla… there is nothing to worry about. Four minutes at top speed and its batteries are pretty much depleted.
As for the BMWs and Ferraris of the world… well, radio waves still travel at 186,000 miles per second.
MICHIGAN STATE POLICE YEARLY VEHICLE TESTS
Every fall MSP, in conjunction with the U.S. National Institute of Justice (NIJ), test the handling and performance of every new police vehicle on the market. These eagerly anticipated tests are seen as the most comprehensive analysis of police vehicles in North America. 2020 will mark the 22nd year Blue Line has reported the results.
The Michigan State Police Precision Driving Unit evaluates police vehicles in two categories: police category vehicles and Special Service vehicles. Police category vehicles are designed for the full spectrum of general police activities including high-speed pursuit. Special service vehicles are designed only for specialized duties such as canine units or adverse weather conditions and are not intended or recommended for pursuits.
Thirteen vehicles were submitted to the NIJ in the police category for the 2020 (and early 2021) model years:
- 2020 Chevrolet Tahoe PPV 5.3L RWD
- 2020 Chevrolet Tahoe PPV 5.3L 4WD
- 2020 Dodge Charger Pursuit 3.6L RWD
- 2021 Dodge Charger Pursuit 3.6L AWD
- 2021 Dodge Charger Pursuit 5.7L RWD
- 2020 Dodge Charger Pursuit 5.7L AWD
- 2020 Dodge Durango Pursuit 3.6L AWD
- 2020 Dodge Durango Pursuit 5.7L AWD
- 2020 Ford Police Interceptor Utility Hybrid AWD
- 2020 Ford Police Interceptor Utility 3.0L EcoBoost AWD
- 2020 Ford Police Interceptor Utility 3.3L AWD
- 2020 Ford F-150 Police Responder 3.5L EcoBoost 4WD
- 2020 Ford Police Responder Hybrid Sedan FWD
These are the police category vehicles that will be available for sale in Canada for 2020 and early 2021 (with figures from the 2020 Michigan State Police vehicle tests, and additional comments from Blue Line.)
Michigan State Police Precision Driving Unit and the NIJ’s Justice Technology Information Center (JTIC) test all the vehicles together over a three-day period at the Chrysler Proving Grounds and the Grattan Raceway. Each vehicle is tested without rooftop lights, spotlights, sirens or radio antennas in place. Tires are original equipment rubber provided by the manufacturer.
Acceleration, braking and top speed tests are performed at the Chrysler proving ground and vehicle dynamics tests are done using the two-mile road course at the Grattan Raceway. (All dimensions and measurements are given in U.S. numbers.)
Vehicle dynamics testing
The objective of the vehicle dynamics testing is to determine the high-speed pursuit handling characteristics. Except for the absence of traffic, the two-mile road course simulates actual pursuit conditions. It evaluates the blend of suspension components and acceleration and braking ability.
Four different drivers test each vehicle over an eight-lap road course, with the five fastest laps counting toward each driver’s average lap time. Final score is the combined average of all four drivers for each vehicle.
Acceleration and top speed
The objectives of the acceleration and top speed tests are to determine the ability of each vehicle to accelerate from a standing start to 60 mph, 80 mph and 100 mph, and to record the top speed achieved within a distance of 14 miles from a standing start.
Each vehicle is driven through four acceleration sequences, two in each direction to allow for wind. Acceleration score is the average of the four tests. Following the fourth acceleration sequence, each vehicle continues to accelerate to its highest attainable speed within 14 miles of the standing start point.
The objective of the braking test is to determine the deceleration rate attained by each vehicle on twenty 60-0 mph full stops to the point of full ABS. Each vehicle is scored on the average deceleration rate it attains.
Each test vehicle makes five measured 60-0 mph stops to full ABS engagement in one direction, and then five measured 60-0 mph stops to full ABS engagement in the opposite direction. After ten stops, each vehicle completes one lap around the test oval to cool the brakes, and the test is repeated.
The resulting score is the average of all 20 stops. Stopping distance from 60 mph is calculated by interpolation of results.
Communications and ergonomics
The objectives of the communications and ergonomics tests are to rate a vehicle’s ability to provide a suitable environment for patrol officers to perform their job, to accommodate required communication and emergency warning equipment and to assess the relative difficulty in installing this equipment. A minimum of four officers independently evaluate ergonomic factors, and Michigan State Police Communications Division personnel then evaluate each vehicle on the ease of equipment installation.
A total of three communications factors are evaluated on a scale of one to 10 and averaged among all the testers. The final score is the overall average of all three factors, including dashboard, trunk and engine compartment accessibility.
A total of 27 ergonomic factors are evaluated on a scale of one to 10 and averaged among all the testers. The final score is the overall average of all 27 factors, such as seat design, padding, ease of entry, head room, instrument placement, HVAC control placement, visibility and ease of entry and exit.
While not an indicator of actual mileage that may be experienced, the EPA mileage figures serve as a good comparison of mileage potential from vehicle to vehicle.
Vehicle figures are based on data published by the vehicle manufacturers and certified by the U.S. Environmental Protection Agency. Mileage figures are given in U.S. miles per gallon.
