VTEC vs Valvetronic: Honda vs BMW Engine Tech 🚗

VTEC vs Valvetronic. Honda versus BMW. Who makes a technology that makes for a better engine? Both technologies are used to alter how much the intake valve opens, thus how much air an engine gets, and thus how much power it makes. Honda’s system, VTEC, acts like a simple switch. At low RPM, the intake operates on a cam lobe with less lift and duration, which tends to be efficient. At high RPM, a pin locks the rocker arms together, forcing the intake valves to operate on a higher lift cam lobe - boom, VTEC kicks in yo! BMW’s system actually eliminates the need for a traditional throttle, because the intake valve can open to any lift height within it’s operating range. It’s far more complex than Honda’s system, but allows for much finer control of your intake valves. What’s your pick?
