This Is Speed Lab

We want to start by setting something straight: “Speed” for our purposes doesn’t just stand for acceleration or how fast a vehicle can go—although we certainly relish testing those limits. It’s about the rapid pace at which the automotive industry is reinventing itself. After decades of slow, steady improvements, we’re now in an age of dramatic change.

In the next year alone, we can expect great leaps in autonomy and fuel economy. Honda, Hyundai, Toyota, and others are in a race to put hydrogen-powered fuel-cell vehicles on the road by 2015—or even sooner, in Hyundai's case. (I tested Toyota’s prototype late last year in Tokyo, and let me tell you, it was a blast to drive.) Meanwhile, Mercedes-Benz and Nissan aim to offer autonomous-driving vehicles by 2020.
