The greenest cars of 2024: Vehicles that use the least fuel and cost less to operate

All-electric vehicles may make headlines for environmental friendliness and fuel efficiency, but the “greenest” car in America in 2024 has a gasoline engine. According to the American Council for an Energy-Efficient Economy's annual GreenerCars ratings of the most environmentally friendly cars, the latest Toyota Prius Prime SE plug-in hybrid tops the list of greenest cars, although it's something of an anomaly, because battery-electric EVs follow it in spots two to five. Of the top 10 vehicles in the ratings, six are electric and four are hybrids: Rank Make & Model Powertrain Green Score MSRP Estimated Annual Fuel Cost* 1 Toyota Prius Prime SE PHEV 71 $32,975 $529 2 Lexus RZ 300e EV 67 $55,150 $651 3 Mini Cooper SE EV 67 $30,900 $747 4 Nissan Leaf EV 66 $28,140 $741 5 Toyota bZ4X EV 66 $43,070 $689 6 Toyota RAV4 Prime PHEV 64 $43,690 $741 7 Hyundai Elantra Blue Gas Hybrid 64 $26,250 $864 8 Hyundai Kona Electric EV 63 $34,050 $695 9 Toyota Camry LE Gas Hybrid 63 $28,855 $907 10 Kia EV6 EV 63 $43,975 $689 11 Toyota Corolla Gas Hybrid 62 $23,500 $944 12 Hyundai Ioniq 5 EV 62 $41,650 $737 *ACEEE analysis using EIA data of annual cost—from gasoline, electricity, or a combination—of driving 15,000 miles The ACEEE also compiled two other vehicle rankings: the so-called “Greener Choices” and the “Meanest List.” The Greener Choices list includes a variety of high-scoring conventional vehicles, and the Meanest List identifies the worst-performing mass-market models. Finishing first in the “greener” list — which the organization says is about cars “available nationwide with among the lowest environmental impacts” — is the Honda Accord Hybrid. As far as the “worst-performing mass market” vehicle, that dubious distinction goes to the $184,000 Mercedes-Benz AMG G63. “ItÂ’s important for automakers to keep expanding affordable EV options rapidly so that the benefits of EVs are available to drivers across a wider spectrum of incomes as we transition away from cars that burn gasoline,” said Peter Huether, ACEEEÂ’s senior transportation research associate and lead researcher for the GreenerCars rankings. “For drivers whose needs are not met by todayÂ’s charging infrastructure, many efficient and affordable hybrid options are available.” Just over half the cars on the 2024 Greenest List start at under $35,000, including four EVs and three gas hybrids.

Toyota develops new pre-collision system with steering assist

A number of automakers are working on developing fully autonomous cars, but it looks like the groundwork for such technologies will likely show up first as semi-autonomous systems for both safety and convenience. Following recent announcements from Nissan and Ford in this area, Toyota has now released information for some of its advanced semi-autonomous technologies that could be offered in production cars over the next few years.
On the safety front, Toyota's new pre-collision system with pedestrian-avoidance steering assist is aimed at protecting the folks who aren't in the car. This system combines visual and audible alerts with automatic brake assist and automatic steering. If warnings don't get the driver to slow down, the brake assist kicks in if a collision is very likely, but if that is still not able to avoid the impending collision (and if there is enough room to do so), the car can automatically steer itself around the pedestrian. This sounds most beneficial for last-second dangers such as a person accidently stepping out into the road in front of a car. Toyota hopes to have this technology available to customers by 2015.
The Japanese automaker is also testing a suite of technologies called Automated Highway Driving Assist (AHDA). The key part of this is a new adaptive cruise control system that uses vehicle-to-vehicle (V2V) communications rather than a radar-based system. This cooperative-adaptive cruise control allows vehicles to communicate their acceleration and deceleration data with other cars, which Toyota says this helps to improve fuel efficiency and traffic flow. Also a part of AHDA is the Lane Trace Control feature, which sounds like a next-gen lane keep assist. This system uses cameras, radar and a computer to keep the vehicle in a "smooth driving line" by being able to change steering angle, engine torque and braking force. Toyota says this technology could be in place by the "mid-2010s."

2021 Toyota Camry AWD vs. midsize all-wheel-drive sedans | How they compare on paper

Just as crossovers have become the dominant body style in the car market, the all-wheel drive they frequently feature has become more popular. In fact, all-wheel drive is so popular that automakers are increasingly putting it in traditional cars. The latest car to add driven wheels is the 2021 Toyota Camry. It will offer all-wheel drive on most of its trim levels, though only with the four-cylinder engine. It isn't alone in this market, though. So we've compiled the Camry's specifications, along with those of a couple of its competitors for comparison. For the purposes of this analysis, we're sticking with the AWD veteran 2020 Subaru Legacy equipped with a naturally aspirated 2.5-liter engine and the relative newcomer 2020 Nissan Altima. Both are similar in pricing and power to Camry. We've skipped the turbocharged Legacy and the turbocharged Ford Fusion with all-wheel drive as both have higher base prices and significantly more power. We'll take a look at these three sedans engine output, fuel economy, pricing and space. Below is a chart with all the raw numbers, and below that is more in-depth discussion of the cars. Performance and Fuel Economy These sedans are very closely matched, but one area where a clear winner emerges is in output. The Camry has a solid 21 horsepower and roughly 10 pound-feet of torque over the Subaru and Nissan. This, despite all of the engines having the same displacement. That power should make it quicker than the approximately 50-pound-heavier Subaru, though the Nissan Altima may stay with it thanks to its curb weight being about 100 pounds less than the Toyota. Also worth noting is that only the Toyota offers a traditional automatic transmission, whereas the Subaru and Nissan rely on CVTs. Subaru and Nissan have both dramatically improved their CVTs to the point they're quite unobtrusive, but if you strongly prefer the feel of softly shifting gears, the Toyota is your choice. In our experience, all three of these sedans are pleasant to drive with suspension and handling clearly tuned in favor of comfort over quickness. Fuel economy is close to a dead heat. Toyota hasn't announced official fuel economy numbers for the all-wheel-drive model, but we can estimate that, as with most all-wheel-drive variants, mileage will be slightly lower than normal models. We're betting it will only about 1 mpg worse than front-drive variants. That puts it in the same 29 to 30 mpg overall range as the Subaru and Nissan.
