What Is 2012 American Le Mans Series

Overview

The 2012 American Le Mans Series (ALMS) marked the 44th season of one of North America’s premier sports car racing series, showcasing high-performance endurance racing across the United States. Organized by the International Motor Sports Association (IMSA), the season featured 10 events, beginning with the 12 Hours of Sebring and concluding with the 10-hour Petit Le Mans at Road Atlanta.

The series emphasized fuel efficiency and innovative technology, aligning with its 'Green Challenge' initiative that scored teams on performance, emissions, and fuel economy. Manufacturers such as Audi, Porsche, BMW, and Chevrolet competed in multiple classes, drawing international attention and strong fan engagement throughout the season.

• 12 Hours of Sebring (March 16): The season opener saw Muscle Milk Pickett Racing dominate the P1 class with their HPD ARX-03a prototype, setting a strong tone for the year.
• Long Beach Grand Prix (April 14): A street circuit event that featured tight competition in the GT class, with Corvette Racing narrowly edging out BMW Team RLL.
• Mid-Ohio Sports Car Challenge (May 5): Level 5 Motorsports won in P2, highlighting the depth of competition outside the top prototype class.
• Canadian Tire Motorsports Park (June 30): Porsche claimed a GT victory here, one of several wins that kept them in championship contention.
• Petit Le Mans (October 20): The season finale at Road Atlanta served as a 10-hour endurance test, with dramatic weather and mechanical challenges shaping final standings.

How It Works

The American Le Mans Series operated on a multi-class endurance racing format, where different vehicle types raced simultaneously but were scored within their own categories. Each race tested reliability, driver stamina, and team strategy over extended durations.

• P1 (Prototype 1):Top-tier prototypes like the HPD ARX-03a and Lola B12/60 were eligible, with engines up to 6.0L naturally aspirated or 4.0L turbocharged.
• P2 (Prototype 2):Smaller, cost-capped prototypes such as Oreca FLM09 and LMPC cars competed here, promoting closer racing and accessibility for privateer teams.
• GT (Grand Touring):Production-based sports cars like the Chevrolet Corvette C6.R and BMW Z4 GTE raced here, modified for track performance and safety.
• GTC (Grand Touring Challenge):Entry-level GT class featuring Porsche 911 GT3 Cup cars, aimed at amateur drivers and smaller teams.
• Challenge Class:Porsche 911-based single-make series provided support races and driver development opportunities across the ALMS weekends.
• Green Challenge:Environmental performance metric awarded points based on fuel efficiency, emissions, and energy use, reinforcing ALMS’s sustainability goals.
