DaimlerChrysler to repave Michigan proving grounds
Chelsea, Michigan – A 7.6 km oval track at DaimlerChrysler’s Chelsea Proving Grounds (CPG) in Michigan will undergo reconstruction this spring and summer to replace its pavement surface. The existing surface, which was laid in 1953, has deteriorated to the point where it no longer provides a test surface acceptable for high-speed testing requirements.
The Chrysler Group uses CPG for new vehicle design development and validation. Several types of tests are conducted at the site, including vehicle durability, emissions certification, crash worthiness, brake development and certification, performance testing, wind and bypass noise testing, steering suspension tests and exposure to hot and cold temperatures.
The CPG has also entered twice into the history books for world speed records: on July 20, 1969, Buddy Baker drove a Dodge Charger Daytona stock car at 203 mph (326.7 km/h), the first time anyone surpassed 200 mph on a closed course. On February 2, 2004, a Dodge Ram SRT-10 was driven by Brendan Gaughan and posted a two-lap, both-directions average speed of 154.587 mph (248.78 km/h) over a “flying kilometre” on the oval.
