In an article published yesterday, the results of this 545-mile trip (originally reported in the Sunday Times in London) were summarized.....
"Whilst the BMW "doesn't have the external look of a green car and you don't get the same self-righteous glow when you are driving it," it does have a series of energy-saving features BMW calls EfficientDynamics: battery recharge when braking, good aerodynamics, low rolling resistance, a continuous fuel consumption gauge on the dashboard, and a six-speed manual transmission that is rated as improving fuel economy by about 10%."(You have to love British reporting style.)
While I don't agree with the statement that the Prius was a "gas guzzler" when compared with the BMW (1.8 mpg less = guzzler?!?), this article is a good overview of the technology BMW uses to achieve their higher mpg ratings on their vehicles.
Any ideas on how to pitch this to my adviser?
