Toyota's refreshed Sai is a Lexus HS by any other name

Toyota first launched Lexus in the United States back in 1989, but it wasn't until 2005 that it brought the luxury marque home to roost. But don't think that Toyota didn't find a way of selling many of its premium models in the Japanese Domestic Market in the meantime. The Lexus LS was sold as the Toyota Celsion, the ES as the Vista and Camry Prominent, and the SC as the Soarer. (We could go on, but you get the point.)
These days Lexus sells in markets around the world, including Japan, but Toyota still spins off its own versions of Lexus models to sell domestically as well. Like the new Sai, for example. Sharing its platform, hybrid propulsion and much more with the Lexus HS (which you may remember as the world's first dedicated luxury hybrid until it was pulled from the market early last year), the Sai was introduced to Japan at the same time as the HS was rolled out around the world. Now nearly four years on the market, Toyota has given it a bit of a refresh.
Boasting a far more aggressive front end and a restyled rear, the revised Sai features LED headlights, 16-inch alloys and a higher-quality interior in which JDM buyers will find a new center console and trim, along with an optional 10-speaker infotainment system. Toyota also boasts that the new Sai is made of 20-percent Ecological Plastic and recycled resin.

This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.
