Toyota’s Chief Engineer Satoshi Ogiso figures that efficiency improvements of traditional gasoline engines may soon hit a wall. He gives the gasoline engine an improvement potential of “maybe 10 to 20 percent.” Today, we have proof that it is a fight of diminishing returns. Mazda is now at a point where it saves up to 10 percent of gas by idling the alternator. How is that done? (Read More…)

As I noted in an earlier piece on the macro-level issues with EVs, it’s dangerously misleading to assume that electric cars can simply replace internal combustion-engine vehicles without a basic re-think of nearly every way in which we relate to our cars. That’s true in terms of consumer-end issues like refueling grid impacts and “range anxiety” but it’s also true in terms of manufacturer-end issues like development and differentiation. It’s even true for the auto media.

One of the giant re-thinks spawned by EV development is in how manufacturers make their vehicles reflect their brand values and stand out in the marketplace, as the electric motor in (say) a Ferrari EV wouldn’t be as fundamentally different as an electric motor in (say) a Kia. This, in turn, makes reviewing EVs extremely difficult, as they all display similar power attributes, weight challenges, single-speed transmissions and battery ranges. So when you are asked to drive a pre-production EV from a major manufacturer, the major question in the mind of the conscientious reporter is the same as the question that drove the vehicle’s development: how is this vehicle different than any other EV? In the case of the Golf blue-e-motion, the answer to that question reflects the challenges of developing a major-market electric vehicle.
