Dr. Heidelinde Holzer is the head of functional integration of powertrain components for BMW AG. Dr. Holzer talked to Lou Ann Hammond, CEO, www.drivingthenation.com, at a media briefing at BMW’s U.S. headquarters in New Jersey on the eve of the 2013 New York auto show.
When will we see a 3-cylinder engine in a car that can be purchased?
We drove a 3-cylinder engine that will go into the BMW i8 plug-in hybrid, produced out of carbon fiber that will have great horsepower (around 350 horsepower) and get over 50 miles per gallon (MPG).
Dr. Holzer explains the downsizing technology of going from a 6-cylinder to a 3-cylinder, going from an equal number of cylinders to an odd number of cylinders.
Wouldn’t 3-cylinders make the car feel lopsided? Dr. Holzer explains how BMW stabilizes the engine.
How does the valvetronic system enhance the 3-cylinder?
Dr. Holzer uses the analogy of dinnerplates under hot lights to explain how they keep fuel efficiency at it’s optimum.
