What to Know About INFINITI’s VC Turbo Engine

Conventional engines have fixed compression ratios, which forces a trade-off between power and efficiency. However, INFINITI’s variable compression turbocharged (VC-Turbo) engine, the world’s first production-ready VC ratio model, overcomes this challenge. INFINITI’s breakthrough technology enables the engine to operate at any compression ratio between 8:1 (for high performance) and 14:1 (for high efficiency), giving you the best of both worlds. Our team at INFINITI of Hoffman Estates created this guide showcasing what to know about INFINITI’s VC-Turbo engine.

How INFINITI’s VC-Turbo Engine Works

The compression ratio refers to the difference between the cylinder volume when the piston is at the top and bottom of its travel. INFINITI’s cutting-edge VC-Turbo engine uses an advanced multi-link system to change the compression ratio based on driving conditions, seamlessly raising or lowering the height of the pistons’ stroke on the fly.

When a change in the compression ratio is necessary, the VC-Turbo’s engine management computer signals an electric motor to move the actuator arm, which rotates the control shaft at the base of the engine and changes the angle of the multi-link system. This adjustment modifies the reach of the pistons, lowering the compression ratio for greater power output and immediate acceleration or increasing it to maximize efficiency at steady speeds, offering unparalleled performance and fuel economy.

Advantages of INFINITI’s VC-Turbo Engine

The INFINITI VC-Turbo engine offers various benefits that make it a standout in the automotive world.

Impressive Power and Efficiency

INFINITI’s VC-Turbo engine delivers exceptional power and fuel efficiency in a revolutionary four-cylinder platform, switching seamlessly between compression ratios between 8:1 and 14:1, depending on driving conditions. For example, the engine adopts a lower compression ratio under hard acceleration or heavy loads to generate maximum horsepower and torque. This configuration provides spirited acceleration and responsiveness that rivals traditional high-performance engines.

During cruising or low-demand situations, the engine shifts to a higher compression ratio to optimize fuel efficiency, offering significant fuel savings without sacrificing performance.

Seamless Engine Transitions

The INFINITI VC-Turbo engine’s sophisticated multi-link system ensures fluid transitions between compression ratios. This feature adjusts the pistons’ reach within milliseconds depending on real-time driving inputs. It does this without any noticeable lag or interruption, delivering a consistent and responsive driving experience. The powertrain adapts automatically, offering robust performance when you want it and efficiency when you need it.

Versatile Driving Modes

The flexibility of INFINITI’s VC-Turbo engine enables you to customize your driving experience at the touch of a button, switching between different driving modes according to your preferences and the road conditions. For example, in Eco mode, the engine utilizes a higher compression ratio to lower power and prioritize fuel economy. This setting is perfect for city driving or long-distance cruising.

Selecting Sport mode shifts the focus to performance. By reducing the compression ratio, the engine maximizes power and throttle response, creating an engaging and dynamic driving experience that’s excellent for winding roads or open highways.

Smooth and Quiet Operation

INFINITI’s VC-Turbo engine design includes advanced noise reduction techniques and an active engine mount vibrating damping system to ensure a smooth ride and quiet cabin experience. The Active Torque Rod system uses a sensor to detect vibrations and creates opposing, reciprocating vibrations, reducing the engine’s noise levels to provide a relaxing environment. INFINITI’s VC technology also contributes to lower engine vibrations, making the engine almost as quiet as a conventional V-6. The engine maintains its composure even during high-performance driving, offering a refined ride.
