5 classic trucks and their polarizing modern revivals

EVs are helping eliminate Detroit's gas-guzzling problem. Some revivals of gas-powered classics are getting the EV treatment.  But not every revived model looks exactly like its original counterpart. We're in a new era of hulking Detroit metal, and you can thank EVs. Americans can't get enough of their big, beefy trucks and SUVs. But for many years, some of the biggest gas guzzlers fell out of fashion as gas prices rose and emissions regulations tightened. But in the past few years, some of the most iconic American truck nameplates have been brought back to life with electric motors, like the GMC Hummer. In other cases, as with the Ford Bronco, improvements in engine technology and more interest in rugged adventure vehicles made a gas-powered revival possible. Even some revivals that started as gas-powered, like the Chevy Blazer and the Jeep Wagoneer, are now getting electrified spinoffs. (Even if they don't always look quite as sleek as their original inspiration.) Here are side-by-sides of five classic American trucks and their modern counterparts. The Jeep Wagoneer 1975 Jeep Wagoneer and 2024 Electric Jeep Wagoneer SStellantis After a long wait, Jeep released its revival of the classic Wagoneer and Grand Wagoneer in 2020. Starting later this year, an electric version of the luxury Jeep SUV will join the Wagoneer lineup. The Chevrolet Blazer A 1973 Chevrolet Blazer and a 2024 Chevrolet Blazer EVGetty Images, General Motors The Chevrolet Blazer was first rebooted in 2019 as a sporty family SUV. The modern Blazer shares zero resemblance to its boxy, off-roading older sibling, but it has still managed to become one of Chevy's more popular SUVs in recent years. The Blazer EV came later, and was one of the first models GM built on its new Ultium battery platform. The Hummer A Hummer H2 and the 2023 Hummer EV pickup truckGetty Images, General Motors Once the poster child for Detroit's big, bad gas guzzlers, the Hummer got new life as an electric pickup truck in 2021. The Ford Bronco A 1971 Ford Bronco and a 2022 Ford BroncoFord Motor Co. After a rouge group of engineers and designers inside Ford spent years trying to breathe life back into the Blue Oval's boxy off-roader, the Ford Bronco was finally resurrected in 2020 amid a rise in popularity for rugged adventure vehicles.

The tricky business of octane, power, and MPG

Given tepid green-car sales numbers this year, consumers in the US aren't making the transition away from internal combustion engines too quickly. Regulations are still mandating cleaner emissions, though. In addition to downsizing and turbocharging, there's growing consideration about moving to higher-octane fuel to improve overall efficiency. In a new report, engineers at FCA, Ford and General Motors Powertrain are showing that it could work, too. The major advantage to higher-octane fuel is that it supports higher compression ratios. That in turn can lead to more power from burning the same amount of gas. "Higher ethanol content is one available option for increasing the octane ratings of gasoline and would provide additional engine efficiency benefits for part and full load operation," the researchers write in the study's abstract. The authors even think it could be possible to update some modern vehicles' engine calibration to be optimized for the better gas. While the benefits are there, we still have a long way to go before higher-octane fuel becomes a national standard. According to Green Car Congress, 87 percent of the gas sold in the US is regular grade 87-octane. Meanwhile, premium 91-93 octane makes up just 10 percent. The various grades of fuel illuminate even more annoyances with the current system. For example, Ford generally recommends 93-octane for EcoBoost engines, and the power outputs that the company publishes are based on using it. However according to Green Car Reports, such premium gas is very difficult to find in some regions of the US, especially along the West Coast. The powertrains still run on lesser grades but with lower power output. The researchers' discussion of possibly increasing ethanol in gas also comes during a heated debate on the substance. The current administration is pushing for less of the corn-based fuel in the coming years. Although, several presidential hopefuls might be favor of reversing that course.

Recharge Wrap-up: California breaks ground on high-speed rail, Ford launches global mobility experiments

California has celebrated the groundbreaking of the country's first high-speed rail system. The ceremony took place in Fresno, in the San Joaquin Valley, situated along the line's initial route through California's Central Valley. The train will travel at speeds of up to 220 miles per hour, delivering passengers from San Francisco to LA in less than three hours when finished by 2029. California eventually plans to extend high-speed rail service north to Sacramento and south to San Diego, with a total of 24 stations. The project is expected to cost a total of $68 billion, but could potentially ease road and air traffic, as well as the pollution that comes with it. See the groundbreaking ceremony in the video below, and read more at Engadget or the California High-Speed Rail Authority website. Elon Musk (barely) commented on the Tesla Model 3 during his Reddit AMA. A commenter asked for any new information on the upcoming electric sedan, to which Musk merely replied, "It won't look like other cars." Unfortunately for Tesla fans, the lone comment was the only reference to the electric automaker Musk leads as CEO. The event was full of some really cool space talk, though. Musk also noted he gets an average of six hours of sleep per night, and that showering is the daily habit that impacts his life the most positively. Read the entire AMA at Reddit. Ford outlined its Smart Mobility Plan at the 2015 Consumer Electronics Show in Las Vegas. It includes 25 global mobility experiments designed to provide insights into the future of transportation needs around the world. "We see a world where vehicles talk to one another, drivers and vehicles communicate with the city infrastructure to relieve congestion, and people routinely share vehicles or multiple forms of transportation for their daily commute," says Ford President and CEO Mark Fields. The mobility experiments include carsharing programs in Michigan, London, Germany and India, a fast-charging infrastructure experiment, a shuttle service in New York and London and even a cycling focused data program in Palo Alto.
