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.

Retro review of the twin-turbo Toyota Supra you missed in the '90s

The twin-turbo fourth-generation Toyota Supra has slowly built up a reputation as one of the premiere sports coupes of the 1990s. The image was partially helped by its inclusion in the original The Fast and the Furious in 2001, but even before that it was part of the quartet of Japanese performance machines along with the Acura NSX, Mazda RX-7 and Nissan 300ZX Twin-Turbo that defined speed for a generation of enthusiasts. Thanks to Motorweek's Retro Review series, now we get a chance to hear opinions on the Toyota from its original release. Two things strike the viewer in the review. First, it shows what a performance standout the Supra TT is. A run to 60 miles per hour in 5.1 seconds and 14 seconds in the quarter mile is strong against its contemporaries and makes it hardly a slouch today. The second surprising thing is just how flabbergasted the reviewers seem at the coupe. The price is up about $8,000 from the previous year, and MotorWeek isn't entirely impressed with the Toyota's weight saving measures that make the fourth-generation Supra a bit more raw than the last model. The great thing about these retro takes is that there's no nostalgia in the way to cloud the reviewers' judgment. Check out the video to find out how the twin-turbo Supra was received before it became part of the performance pantheon.

2022 Lexus IS 500 F Sport Performance brings back the V8

The 2022 Lexus IS 500 F Sport Performance revives the dormant IS F formula, bringing V8 power back to the compact luxury Japanese sport sedan for the first time since 2014 and confirming rumors of a new series of V8-powered performance (small p) cars from Lexus. Very little surprises us these days, especially in the luxury segment, but if you'd told us a month ago that we'd be confirming a V8-powered Lexus IS and a new, all-four-cylinder lineup for the Mercedes-Benz C-Class in the same week, we'd have called you crazy. Parent company Toyota's presence in Texas may have rubbed off on Lexus, though, because after a years-long hiatus, the V8-powered IS sedan returns. That's right. A V8. In a brand-new compact sport sedan. In 2021.  The new sport sedan will pack a 472-horsepower, 5.0-liter V8 with 395 pound-feet of torque, making it the spiritual successor to the discontinued Lexus IS F. For those keeping track at home, yes, that's the same V8 Lexus has utilized elsewhere in recent years. It currently powers the RC F coupe and, until last year, was also found under the hood of the larger GS F sedan. Like the BMW M3 it matches for power, the Lexus will come standard with rear-wheel drive and a limited-slip differential, making it a true performance machine. Power will go to the rear end by way of the same eight-speed automatic Lexus uses elsewhere as well. Sorry, folks, there's no stick, but hey, the IS F didn't have one either, so let's not get too picky. The original IS F also offered just 416 horsepower and 371 lb.-ft. of torque, so remember, this is all upside here. The original also launched without the LSD, if you'll remember; that came later.  2022 Lexus IS 500 F Sport Performance View 26 Photos The other significant edge the IS 500 F Sport Performance will have over its two-generations-removed predecessor will be the benefit of almost a decade's worth of interior development. While the IS platform was not significantly overhauled for the 2021 "re-imagining" (as Lexus puts it; we prefer the term "remodel"), the interior was, and the IS 500 F Sport Performance will benefit from all of the base sedan's upgrades, including a thoroughly overhauled infotainment system, which is night-and-day better than what was offered previously.
