Overview

The 2012 American Le Mans Series (ALMS) marked the 44th season of endurance sports car racing in North America, featuring high-performance prototypes and grand touring cars competing across multiple classes. The season spanned from March to September, showcasing 10 grueling events that tested speed, strategy, and mechanical endurance.

Organized by the International Motor Sports Association (IMSA), the 2012 season highlighted technological innovation and manufacturer rivalry, with Audi, Porsche, BMW, and Chevrolet among the key participants. The series emphasized fuel efficiency and alternative energy, aligning with its 'Green Challenge' initiative to promote sustainable racing.

Muscle Milk Pickett Racing dominated the P1 class, securing the championship with victories at Sebring, Long Beach, and Petit Le Mans.
Corvette Racing earned the GT title, winning six of the 10 races with their Chevrolet Corvette C6.R driven by Antonio Garcia and Jan Magnussen.
The season opener, the 12 Hours of Sebring on March 15, featured 58 entries and set a tone of intense competition across all classes.
HPD (Honda Performance Development) took the P2 class manufacturers' title, with teams like Level 5 Motorsports winning seven races.
GTC class was fiercely contested, with Alex Job Racing’s Porsche 911 GT3 Cup winning four times and clinching the team title.

How It Works

The ALMS used a multi-class racing format where different vehicle types competed simultaneously, with results separated by class. Each race emphasized endurance, fuel strategy, and driver rotations, typically lasting 2.5 to 12 hours.

P1 (Prototype 1): The top-tier class featured custom-built, closed-cockpit prototypes like the HPD ARX-03a, limited to 500 horsepower and using advanced aerodynamics.
P2 (Prototype 2): Slightly smaller and less powerful than P1, P2 cars like the Oreca FLM09 used 2.8L V6 engines and were capped at 450 horsepower.
GT (Grand Touring): Based on production sports cars, GT vehicles like the Corvette C6.R and BMW Z4 GT3 featured modified V8 engines and weighed approximately 2,800 pounds.
GTC (Grand Touring Challenge): A cost-capped class for amateur drivers, using Porsche 911 GT3 Cup cars with 450-horsepower flat-six engines and standardized parts.
Green Challenge: A scoring system awarded points for fuel efficiency, emissions, and performance, encouraging hybrid and alternative fuel technologies.
Race Duration: Events ranged from 2-hour 45-minute sprints to 12-hour endurance marathons, requiring multiple driver changes and pit strategy.

Comparison at a Glance

The 2012 ALMS featured diverse vehicle specifications across its four primary classes:

Class	Top Team	Engine	Top Speed	Championship Points
P1	Muscle Milk Pickett Racing	4.0L V8 (Nissan)	210 mph	188
P2	Level 5 Motorsports	2.8L V6 (Honda)	195 mph	177
GT	Corvette Racing	7.0L V8 (Chevrolet)	190 mph	172
GTC	Alex Job Racing	3.8L Flat-6 (Porsche)	175 mph	168
Overall	Muscle Milk Pickett Racing	N/A	N/A	188 (highest)

While P1 cars were the fastest and most technologically advanced, the GT and GTC classes attracted major manufacturers due to closer ties to consumer vehicles. The table illustrates how different engineering priorities shaped performance and competitiveness across the board.
