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 may return to F1 under Lexus banner

A new report in from the website Club Lexus claims to have insider knowledge about a return to Formula One racing by Toyota, this time under the auspices of the Lexus brand. Toyota competed in F1 from 2002 through the 2009 season. That final year saw the team return competitive, if inconsistent results, but the larger economic woes in the automotive market made a decision to pull the plug relatively easy at the time.
Now, citing recent interviews with Toyota executives and insider sources, Club Lexus says that the move to re-enter F1 for the 2014 season is "all but finalized." The choice to go with the Lexus nameplate over Toyota makes some sense, too, considering the success that rival Infiniti has had in recent years through its partnership with Red Bull Racing. Further, the emerging Lexus identity as a performance car builder, with a strong background in hybrid vehicles, could help the F1 move resonate with buyers.
A few technological factors and formula changes within F1 offer some credence to the Lexus rumor, too. F1 will increase the available capacity of KERS from 60kW to 120kW, a change that theoretically benefits the hybrid-savvy Toyota. What's more, 2014 will see a switch from the current 2.4-liter V8 engines to 1.6-liter turbocharged V6s. A Lexus team that goes racing in 2014 will be on a level playing field with the rest of the grid then, with all teams adjusting to and continuing to develop the new engines.

Why is there a huge bulge in 2021 Lexus IS 300 AWD's driver footwell? We explain

After an initial turn a few weeks ago for the 2021 Lexus IS first drive review, the revised luxury sedan has returned to the Autoblog garage for a second look. This middle-of-the-road IS 300 AWD pairs a 260-horsepower V6 with a six-speed automatic transmission and four driven wheels, and frankly it's the least interesting way to spec out the redesigned sedan. While there are cars in this segment designed to get a performance boost from their all-wheel-drive systems even in dry conditions, the IS isn't one of them. Adding insult to injury, you get stuck with a cramped driver-side footwell care of the engineering shenanigans that went into making this system possible.  While we've mentioned this particular compromise before, we rarely touch on the reasons why it exists in the first place. The fundamentals are fairly obvious; the standard IS utilizes a longitudinal, rear-wheel-drive powertrain. As is typical with this configuration, the transmission sits in a tunnel beneath the center console. This arrangement works just fine, provided you don't need to power the front wheels.  To do so in a traditional car like the IS requires a literal end-around maneuver involving the engine and transmission, which we've diagrammed for you below care of MSPaint. This is a bit simplified for the sake of this write-up, and it should be noted that this is not the only way to implement AWD in an inherently RWD platform, but it illustrates how the power for the front axle (red) and rear axle (blue) flows from the transmission to the drive wheels. To get juice flowing to the front axle, Lexus had to add a parallel output shaft, exiting the transmission from the front with enough clearance for the bell housing and engine, which sits between the transmission and the front differential. This requires quite a bit of lateral reach, meaning the housing has to extend much farther out than usual to accommodate it (yellow arrow). As a result, the all-wheel-drive transmission looks a lot like a sci-fi gun with a chunky drum magazine hanging off the side of it. The hump (above right) in the footwell is there to clear this protrusion. This basic configuration isn't unique to Lexus. In fact, if you look at a BMW xDrive cutaway, it's similar. So, why no "hump" in other cars? There are multiple factors, but to boil it down to what is most relevant, it's a combination of the resulting shape of the Lexus transmission housing and the size of the IS chassis.
