VTEC Technology revolutionized engine performance and fuel economy for Honda, with variations like SOHC VTEC and i-VTEC enhancing efficiency and power. Known for durability and high power output, Honda’s VTEC engines continue to be used in popular models today. Originating in the Japanese Bubble Era, VTEC changed Honda’s trajectory, particularly in performance cars like the Civic and NSX. The technology was first featured in a bike in 1983 before making its way to cars, with the 1989 Honda Integra XSi being one of the first vehicles to showcase VTEC in action. The B-series engine was the first to feature VTEC, operating on a system of switching between mild and aggressive cam profiles for optimal performance at different RPMs. Over the years, Honda has developed different variations of VTEC engines, such as DOHC VTEC, SOHC VTEC, and VTEC-E, each aimed at improving performance and fuel efficiency. Honda’s VTEC technology has set the standard for variable valve timing systems in the automotive industry, leading to continued advancements and improvements in engine technology.
