Excitement Meets Efficiency with VCM.
Accord V-6 models with the 6-speed automatic transmission feature Variable Cylinder Management™ (VCM®) for the best of both worlds.
The 2013 Accord’s new, more powerful V-6 can also stretch fuel further with an overall improvement in fuel efficiency compared to the outgoing model. Plus, it offers greater smoothness and more consistent power delivery than the turbocharged 4-cylinder engines in some competitive cars.
How does VCM work? During startup, aggressive acceleration or when climbing hills – any time high power output is required – the engine operates on all six cylinders. During moderate-speed cruising and at low or moderate engine loads, the system operates on a reduced number of cylinders.
The VCM system can change the working displacement of the engine to match the driving requirements from moment to moment. It’s like having a small engine when you only need a little power and a big engine when you really need to move. Since the system automatically closes both the intake and exhaust valves of the cylinders that are not used, pumping losses associated with intake and exhaust are eliminated and fuel efficiency gets a further boost.
The VCM system combines maximum performance and maximum fuel efficiency – two characteristics that don’t happily coexist in conventional engines. Glad to say they get along just fine in the new Accord V-6 automatic. An archive of this message is available here.
