Race Distance: 184.8* miles/296.76* km (66 laps on the 2.8*-mile/4.51*-km temporary street circuit).

*-Precise distances will be determined following measurement of new official track length this week.

Potenza Race Tires Supplied: Bridgestone delivered 740 dry-condition ("slicks") and 320 wet-condition ("rains") Potenza race tires for use this weekend. All were produced at the Bridgestone Technical Center in Akron, Ohio. Per Champ Car World Series regulations, Bridgestone brought two dry-tire specifications and a single wet-tire spec, broken down in the following manner:

* Standard dry-condition tires: Each car receives six sets of standard specification slicks (24 tires) for the weekend, to use in the practice, qualifying and race sessions. New for 2006, the primary Potenza selected for Mexico City falls into the mid-range for "softness" in the current Bridgestone road-course tire family. The same specification served as the standard spec tires for races earlier this season at Cleveland and Edmonton.

* Alternate dry-condition tires: Each car receives two sets of alternate slicks (eight tires) to use this weekend; they are easily identified by their bright red sidewalls. At least one set of alternates must be used for a stint in Sunday's race. The Bridgestone alternate tire's construction is identical to the standard slick, but the alternate possesses a tread compound with better grip ("softer"), making it faster but possibly not quite as durable. The alternate Potenza for this weekend was previously used this season as the alternate selection at Portland and Montreal.

* Wet-condition tires ("rains"): Each car receives up to four new sets of grooved-tread Potenza rain tires (16 tires) per weekend on road and street courses, as needed. In addition, each car may use two sets of same-spec rain tires issued at a previous event. Bridgestone opted for more dur able rain-tire specification for the long Mexico City course this weekend.

Quote from Al Speyer, Executive Director, Bridgestone Motorsport: "Another great Champ Car season comes to a conclusion this weekend in Mexico City. We must congratulate Sebastien Bourdais for etching his name alongside some of the greats in motorsports history with his third consecutive championship. While the title may have been decided, that should not detract from what is always an exciting event in front of the energetic Mexico fans. All three of the Bridgestone tire specifications available this weekend are proven commodities. The Potenza alternates provided nearly a second per lap advantage to the standard slicks last year at Mexico City, so tire performance should be an integral part of the competitive story again this weekend. We're eager to see how it unfolds."
