The Wikipedia article on VTEC should be good at helping you understand it all. VTEC is a trademark of Honda’s patented technology (the original patents have expired but Honda have patented newer implementations such as A-VTEC). So no other manufacturer’s production engine can do exactly the same thing.
- What is a Honda VTEC engine?
- Perhaps one of the greatest selling points of the Honda VTEC system is the fact that it is one of the strongest engines in its class. Reaching 160 kW @ 7,500 EPM, the VTEC engine uses air circulation technology to increase the airflow through the cam, easily changing it to a lower angle.
- What is Honda i-VTEC?
- Honda i-VTEC is intelligent variable valve timing and electronic lift control system that is engaged at 3,500 rpm. The main purpose of that system is to provide high fuel efficiency together with max performance. The R18 doesn’t have hydraulic tappets (checking and adjusting valve clearance is needed every 25,000 miles or 40,000 km).
- What is VTEC & how does it work?
- Honda developed its Variable Valve Timing & Lift Electronic Control (VTEC) technology to make its cars quicker, more efficient, and more enjoyable to drive overall. The technology’s frequent appearance in Fast and Furious movies has turned it into a widely known meme. Many have heard the phrase “VTEC just kicked in, yo!” but few know how it works.
- When was VTEC first introduced in a motorcycle?
- Apart from the Japanese market-only Honda CB400SF Super Four HYPER VTEC, introduced in 1999, the first worldwide implementation of VTEC technology in a motorcycle occurred with the introduction of Honda’s VFR800 sportbike in 2002.
- Is VTEC fuel efficient?
- The variable valve timing and electronic lift control technology optimize engine response giving it power and fuel efficiency at the same time.
