Although they are not known for it, hybrid engines can actually be used to enhance performance, rather than fuel economy. Given the current climate (and fuel prices!) it’s understandable the more successful hybrid cars (i.e. the Toyota Prius) gets more air time, but there have been some performance hybrid cars out there.
What Makes a Hybrid a Hybrid
But first, the basics. What is a hybrid car and what do I mean they can be tuned for performance? A hybrid car is, once you get down to it, a merger of two engines. Normally, one of the engines is gas (or diesel) and the other is an electric motor. There are other hybrids out there, including fuel cell/electric or fuel cell/gas hybrids, but for the most part when someone says hybrid, they mean gas/electric vehicles.
Now, by mating a gas and an electric motor together, you can actually use the strengths of each to complement each other. For instance, electric motors can give you a very good acceleration, because they provide constant power, while gas engines are less efficient. But in constant road conditions (highway traveling), the power supplied by the gas engine is easier to manage (and it’s a lot easier to refuel with gas). The constant drain on a battery at highway speeds just isn’t as efficient.
In city driving (frequent stop and go), you can recharge the battery pack through regenerative braking. Out on the highway, the gas engine is needed to power the battery pack.
BTW, hybrids tend to have very efficient gas engines, so the myth that says if you have a highway commute you shouldn’t buy a hybrid doesn’t make a lot of sense to me. The Prius gets 45 mpg on the highway. Most people would be ecstatic to get half that.
And so, automakers have used hybrid technology to emphasize the two motors strengths. Electric motor powers the car at low speeds, while the gas engine takes over at highway speeds. Put them together and you get a more efficient vehicle. But efficiency in a car can be taken in other directions. Instead of emphasizing fuel efficiency, you can emphasize power efficiency. And that’s just what Honda did with the Accord Hybrid. Continue Reading…
