Video: How the Chevy Corvette ALMS engines are built
The Chevrolet Corvettes that do battle in the American LeMans Series are, at first glance, acres removed from their street-dwelling cousins. Beneath the skin, though, the two cars are more similar than you might think, given their differing purposes.
For starters, Chevrolet uses similar engine architecture for both cars. The ALMS Vettes use the exact same block that goes into the Corvette Z06. That's where the similarities end. The racing engine is limited to two 28-mm air intakes in a bid to level the GT Class playing field. The ALMS engines are also limited to 5.5 liters of displacement, versus the production car's 7.0 liters.
Though the means may be different, the end is the same: maximized power and efficiency. Chevrolet develops and builds its racing engines in-house, to try and insure that some of the technology that goes into its endurance racers makes it into its street cars.
