A lot can happen in a decade in the world of sports, politics, art, technology and life in general. The same can also be said about the auto industry. Aside from the Volvo XC90, every surviving model has gone through at least one complete generation and some are on their third. With that in mind let's take a look at five models over the past decade that have had the greatest impact on the industry through their design or technology. The list is in chronological order to avoid picking favorites.
2004 Toyota Prius
It wasn't the first hybrid, it wasn't even the first Prius but the second generation Prius was the one that put hybrids on the map and eventually made nearly every automaker produce their own. Even the German brands. The second generation brought about 20% better city and 10% better highway fuel economy, at the time the Prius posted an unrealistic 60 mpg city and 51 highway labels*. Even more importantly the Prius brought a unique shape to the market in a usable size. The first generation Prius had an awkward sedan shape that didn't help its cause. Toyota would commit the same exact mistake a few years later with the Lexus HS hybrid that struggled to sell as well. The second generation Prius didn't make hybrids cool but it made them mainstream relevant. The latest million dollar halo cars from Ferrari, McLaren and Porsche are all... hybrids.
