Unless you’re a racing fan or work in the industry, the types and classes of racing can be a little confusing.
When talking about racing, there are four different types:
1. American Le Mans Series (ALMS)
2. Formula One
3. IndyCar Series
4. Nascar
However, unlike the other three, ALMS has different classes of cars all racing on the same track.
2010 Le Mans Prototypes 1 (LMP1) Class Champion
These ultra-engineered racing cars typically produce between 475-575 horsepower, have a minimum weight of approximately 1,985 lbs, can accelerate from 0-100 mph in 4 seconds and reach top speeds near 200 mph. All LMP1 race cars have red Leader Light System race position lights and red car numbers.
2010 GT Class Champion
The GT class is comprised of production-based, moderately modified two-wheel drive race cars. With top speeds of up to 180 mph, these elite GTs produce between 450-500 horsepower and have a minimum weight of 2,480 lbs. All GT race cars have green Leader Light System race position lights and green car numbers.
2011 Le Mans Prototypes 2 (LMP2) Class
Smaller and less powerful than their LMP1 counterparts, LMP2 cars can produce similar horsepower figures to GT cars (450-500) with speeds up to 170 mph but weigh 900 kilograms. All LMPC race cars have blue Leader Light System race position lights and blue car numbers.
2010 LMP Challenge Class Champions

All LMPC race cars have yellow car numbers and a single green light at the rear of the car.
2010 GT Challenge Class Champion
The GT Challenge class features the Porsche 911 GT3 Cup car. With 450 hp and top speeds of up to 150 mph, the minimum weight is approx. 2,655 pounds. All GTC race cars have orange car numbers and a single green light at the rear of the car.
