    Chrysler Chelsea Proving Grounds Hosts 2008 Michigan State Police Vehicle Evalua



    More than 200 police and public safety department representatives converged on the Chrysler Chelsea Proving Grounds today to take part as observers in the 2008 Michigan State Police Vehicle Evaluation.

    Conducted by the Michigan State Vehicle Test Team, this annual event is widely considered to be the national benchmark evaluation of police and special-service vehicles. Many jurisdictions base their fleet purchasing decisions of the performance data generated by this multi-day, multi-venue test.

    Michigan State Police tested a number of vehicles from Chevrolet, Dodge and Ford and motorcycles from Harley-Davidson and BMW. In last year's test, the Dodge Charger and Dodge Magnum were the top performers in all automotive categories. Results and methodology can be found at http://www.michigan.gov/documents/ms...p_182663_7.pdf.

    The event officially christened the newly resurfaced Chelsea Proving Grounds High-Speed Oval. The 4.71-mile high-banked track underwent a comprehensive $12 million reconstruction over the spring and summer, the first since it was originally laid in 1953.

    Seen from the air, the oval is a six-lane asphalt road, and is in nearly continuous use. The banking in the turns is designed to accommodate vehicle speeds from 30 to 140 mph without producing any lateral loading.

    When not hosting the Michigan State Police, the Chelsea Proving Grounds are utilized by Chrysler for new vehicle design development and validation. Several types of tests are performed at CPG, including vehicle durability, emissions certification, crash worthiness, brake development and certification, performance testing, wind and pass-by noise testing, steering-suspension tests, exposure to hot and cold temperatures -- prior to the vehicles being brought to the marketplace.

    The Chelsea Proving Grounds evaluate 29,300 emissions test miles, 11 million durability test miles and 750 crash tests each year.

    In addition to validating vehicles to prepare them for on-the-road driving, the Chelsea Proving Grounds have also hosted their share of historical moments including two world speed records.

    The first was set July 20, 1969, by Buddy Baker in a high-winged Dodge Charger Daytona NASCAR stock car. Running high-speed tests prior to its competitive debut, the car went 203 mph, marking the first time anyone had ever gone over 200 mph on a closed course. Because the location was the Chelsea Proving Grounds, the record was never officially published.

    On Feb. 2, 2004, the Chelsea Proving Grounds and the Dodge Ram SRT-10 made history, entering the Guinness Book of World Records as the "World's Fastest Production Pickup Truck." The Dodge Ram SRT-10 -- driven by NASCAR Craftsman Truck Series star Brendan Gaughan -- posted a two-lap, both-directions average speed of 154.587 mph over a "flying kilometer" on the oval.

    The 3,850-acre Chelsea Proving Grounds site in Sylvan Township is just south of the Village of Chelsea, covering an area approximately two by three miles wide, and contains approximately 95 miles of test roads, including: the high-speed oval; two straightaways, 1-1/2 and 2-1/4 miles long; a skid-traction facility; a 14-acre paved vehicle dynamics area with a three-mile oval; a handling and evaluation road; a replica of the Rubicon Trail off-road test;and several accelerated durability. In addition to the network of roads, there are a number of buildings on the site totaling approximately 750,000 square feet. The facility, which opened in 1952, employs 675.

    Yeah, that seems like a totally realistic, real-world test of the abilities of these vehicles in the field...

    And that's what cop cars are all about, fun.

    Well, high-speed handling characteristics and durability under abusive conditions must also be evaluated. That is part of the reason for the high-speed test loop.

    Did you read my quoteback? "The banking in the turns is designed to accommodate vehicle speeds from 30 to 140 mph withoug producing any lateral loading." That's no test of handling at all. It's the opposite. It's like being able to do laps on a dragstrip.

    Trust me, the course was not built for "fun" - and the tests are done for serious reasons. It may be fun to do the tests, but that's another matter!

    The purpose of the tests is to subject the cars to various conditions it would be hard (or dangerous to publis safety) to reproduce on the street. What specific thing they were evaluating in this case I can't say from the text - but I assure you they don't use the proving grounds as an amusement park..

    A high-speed oval like that, that doesn't produce any lateral loading, would only be good for sustained high speed testing.

    What they need is a "sustained idle outside a donut shop" test.

    Well that's a bit of a red herring, since YOU were the one who brought up the subject of fun in the first place.




    But if a banked oval is the major portion of Chrysler's test track, then it's no wonder they've never made a car with decent real world handling.

    The Proving Grounds encompass a very large area and include a wide variety ot test loops/roads designed to replicate "real world" conditions in a controlled environment. The high speed circuit is just one element of the testing. I'm sure there are good reasons for evaluating police vehicles as described in the original story; that doesn't mean the drivers aren't enjoying their work, though.

    Oh. The article only mentioned the oval.
