BMW 3-cylinder engine like a 6-cylinder

A BMW 3-cylinder that drives like a 6-cylinder engine

Dr. Heidelinde Holzer is the head of the 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 North American International Auto Show (NAIAS)

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 dinner plates under hot lights to explain how they keep fuel efficiency at it’s optimum.
