How do you make power even more powerful? ZR1 engineers were tasked with that mission. Charge air coolers paired with dual mono-scroll, ball-bearing turbos work together to deliver unrelenting power, along with integrated exhaust manifold turbos to provide the quick responsiveness you expect. Electronically controlled waste gates combined with other engine controls virtually eliminating turbo lag – especially during more dynamic driving situations. To sum it up, you get more power in less time and massive torque out of the gate. Mission accomplished.
Completely unique to the LT7 engine, the Edge Blue Intake System brings air from the charge air coolers into the engine's intake manifold, where it's mixed with fuel from two systems: Port and Direct Injection (PDI). The cool air and fuel mixture are then sent into the combustion chambers, where it ignites and drives the never-ending torque. Prepare for takeoff.
The goal was to take power and performance to the next level. That goal was achieved with the LT7 engine. A unique cylinder head casting with updated combustion chambers works seamlessly with the intake system to help increase airflow and reduce compression ratio, while the exhaust port enables an optimized turbocharging system. The valve train was refined for boosted performance to bring the powerful output you expect. This is more than an engine. This is a system that knows the difference between just moving and making power moves.
The crank train supports extreme force as it converts pressure into torque and horsepower. The flat-plane crankshaft is the backbone that holds it all together, allowing seamless interaction with other engine parts, such as the stronger forged pistons. The wrist pin is bigger and thicker with stronger forged titanium rods. The piston converts the energy released during combustion into mechanical work as it reacts against the titanium rod. Every part has a purpose because when it comes to achieving power, it doesn’t happen alone.
One of the most unique and recognizable Corvette attributes now features ventilation and a louvered spine for increased engine bay cooling – integrating form and function. This is paired with new carbon-fiber hatch intakes to draw in colder air for improved engine performance.
Designed with the known strength of carbon fiber to reduce section width and mass and improve aerodynamics.
A smooth underbody minimizes drag and reduces turbulence underneath ZR1, and also helps to engage downforce.
The flat-top and -bottom steering wheel makes the unique ZR1 badging the focal point. A heated, leather-wrapped steering wheel with carbon-fiber accents is standard. Or opt for the sueded microfiber-wrapped steering wheel, only available on 3LZ.
