Is there a timing chain in the 2019 Infiniti Q50?

The 2019 INFINITIQ50 features a timing chain instead of a timing belt. The decision to opt for a chain was made because it offers a much longer lifespan compared to a belt, sometimes lasting even longer than the car itself is in service. Additionally, there are various advantages to using a chain over a belt. Belts have a tendency to stretch over time, leading to unpredictable timing variations. Moreover, rubber, which belts are made of, does not hold up well against oil, gas, and coolant – substances that are commonly found in the engine bay. Despite the clear benefits of using a chain, some manufacturers still choose to use belts due to cost considerations. Belts are much cheaper to produce compared to chains, making them a cost-effective option when aiming to keep the manufacturer's suggested retail price as low as possible.
