2010 Chevrolet Corvette Grand Sport
Dry-sump oil systems are the apple of many a race-engineer's eye, and the technology has been making its way into passenger cars for some time now. Chevrolet's Corvette range is one of those adopters, having dry-sump oil systems in the ZR1, Z06 and, for 2010, the Grand Sport.
Though all three of those cars use similar small-block V-8 engines, they are all different: the ZR1 uses the supercharged 6.2-liter LS9, the Z06 uses a 7.0-liter LS7, and the Grand Sport uses a modified version of the 6.2-liter LS3. All three applications use the same dry-sump oil tank, however.
The main purpose of a dry-sump oil system is to allow an engine to pull higher g-forces without causing oil starvation issues than would be possible with a standard wet-sump oil system. In some applications, the lack of a tall oil pan on the bottom of the engine also allows it to be placed lower in the chassis, lowering the car's overall center of gravity and further improving performance.
