The new mid-engined Chevrolet Corvette Stingray also comes with a brand new engine that sits snugly in the middle. Here’s how it works.
The 2020 Stingray is powered by the 6.2-L LT2 V8 engine. It’s an evolution of the LT1 engine that powered the C7-generation Stingray and is much more powerful. Without the performance exhaust from the Z51 Performance Package, the LT2 produces 490 horsepower and 465 lb-ft of torque. That’s 40 more horsepower than the LT1. With the performance exhaust, the engine produces 495 horsepower and 470 lb-ft of torque.
It also sits low and in the middle of the chassis, unlike the LT1. This provides the new Corvette with better weight distribution and a lower center of gravity for enhanced handling.
It also sits below a clear glass hatch, meaning that the entire world will see this engine at work at all times. GM engineers were forced to consider aesthetics in its design far more than any other engine they built. According to Chevy's press release, "Every part, including the exhaust system’s wires, tubes, routing fasteners, coolant hoses, exhaust manifold, and even the bolts and fasteners, is built with appearance in mind."
The LT2 also uses a completely redesigned dry-sump system. In most wet-sump engines, oil collects in a large reservoir at the bottom (called the oil pan) and is distributed throughout by a single pump. In a dry-sump system, oil is actively scavenged from the engine through two or more pumps and collects it in a single reservoir (the sump). Then another pump distributes that oil throughout the engine.
A dry-sump system is far better able to deal with prolonged usage as it circulates far more often and the additional pumps help maintain oil pressure. This additional circulation helps to keep the engine cooler during long race sessions and is why you’ll often see dry-sump engines in performance and racing applications.
The dry-sump is also what allows the engine to be placed lower down on the chassis. Without a bulky oil pan to worry about, Chevy engineers were able to place this motor an inch lower to the ground.
