The problem with battery electric and fuel cell cars is gasoline. Petrol is genuinely a superior fuel, at least in terms of energy. It has so much energy per gallon, 116,000 btu/gal, that we can use it in an engine whose theoretical maximum efficiency is only 37%. That means that with all the gizmos a modern gasoline powered internal combustion engine has that increase fuel economy, still two thirds or more of the energy in the fuel is being turned into unusable heat, not motive force.
I’ve been driving the 2014 Mazda 6 GT w/ Mazda’s SkyActive Technology Package for about a week now. It’s a stunner, looking for all the world like the kind of sports sedan Aston Martin would build if it had any stones. On top of that, the car has some seriously trick fuel-savings features and, I must admit, handles brilliantly (even on my tester’s Blizzak winter tires). For each of the Mazda’s highs, however, there is a low, and I will do my very best to remain objective as I share these, leaving you, dear reader, to decide whether the highs outweigh the lows.
Get comfy, then. We’re about to get weird.
Even though we’re subjected to relentless claims that the golden age of automobiles has long passed us, I can think of worse things than a 900-horsepower supercar with C02 emissions comparable to a Scion FR-S.
