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.

Toyota outsells VW for global sales crown, apologizes with a vow to 'be honest'

Toyota Chairman Akio Toyoda bows in apology during a press conference Tuesday over the group companies' quality scandals. (Getty Images)   Every quarter, the stock market hangs on how much sales growth Tesla and other startups have experienced. There's growth, but then there's sheer output, and when it comes to deliveries dominance, one company can't be touched. Toyota on Tuesday announced that it remained the world's top-selling automaker for the fourth year running, with record sales of 11.2 million vehicles in 2023. Toyota's global group sales jumped 7.2% last year; the numbers include sales at Daihatsu and truck unit Hino Motors. Toyota's parent-only vehicles, which include the Toyota and Lexus brands, hit a record of 10.3 million vehicles in 2023. Gasoline-electric hybrids made up about a third of those. Battery electric vehicles accounted for less than 1%. Toyota's annual output handily beat runner-up Volkswagen Group, which this month reported a 12% rise in deliveries last year to 9.2 million cars. That growth was driven largely by demand for Audi, which sold 1.9 million vehicles. The auto industry in 2023 enjoyed a post-pandemic recovery as supply chain bottlenecks eased, though shipping problems through the Red Sea so far this year have stalled that progress by some automakers, causing some car plants in Europe to suspend production. Toyota's global group sales have now topped 10 million vehicles for nine of the past 10 years, except for 2020 when the COVID-19 pandemic delivered a blow to the auto sector. Scandals and an apology Toyota's chairman apologized on Tuesday for scandals at the three group companies. Daihatsu, Hino and affiliate Toyota Industries have been beset by governance issues involving certification test procedures for cars and engines that could potentially hurt the brand's global reputation for quality and safety. "I would like to express my deepest apologies to our customers and stakeholders for the inconvenience and concern caused by the successive irregularities at Hino Motors, Daihatsu and Toyota Industries," Toyota Chairman Akio Toyoda told reporters. He was speaking at an event to announce a vision for the Toyota group, which was founded by his great-grandfather and now includes 17 companies.

Lexus LFA prototype spied lapping the Nurburgring with new bodywork

The Lexus LFA was a real engineering tour de force. Sure, it was stuck in development hell for years, and the 4.8-liter V10's 552-horsepower output wasn't super impressive when it came out, but it integrated a ton of expertise Toyota gained from its F1 team in the early to mid 2000s. Unfortunately, it didn't sell well. Last year, we found there were a few new models sitting on dealer lots, five years after the 500-model run ended. Still, it looks like Toyota may not have given up on the idea of a race-derived flagship for Lexus, at least based on this prototype running around the Nurburgring this week. At first glance, the car pictured here looks like an LFA with the Nurburgring Package and some camouflage on the front and rear fenders. If you look closely, you can see that the fenders are significantly wider than on the standard LFA. Based on the license plate, this appears to be the same car with two different sets of wheels. Lexus may simply be swapping out worn tires, or they may be testing different wheel and tire combinations to fit the wider wheel wells. Anything beyond this is just speculation. There have been rumors of a new flagship Lexus sports car that sits atop the LC 500 and LC 500h. We saw the Toyota GR Super Sport Concept back in January, though that car looks nothing like what we see here. As much as we would love that sweet Yamaha co-developed V10 to carry over, we're not holding our breath. Some sort of hybrid powertrain is almost a certainty. Maybe Lexus and Toyota could pull some tech from its Le Mans-winning TS050 Hybrid race car. Related Video:
