GM trucks get hybrid versions, but you'll probably never see one

A few years ago, General Motors sold hybrid versions of its Chevy Silverado and GMC Sierra pickups. They weren't very good, using GM's old two-mode hybrid system that resulted in only negligible fuel economy gains. But GM's trying again, launching eAssist models of the 2016 Silverado and Sierra that are said to offer 2-mpg improvements in city, highway, and combined fuel economy ratings. Problem is, you probably won't be able to get one. Only 700 eAssist trucks will be made for the 2016 model year – 500 Silverados and 200 Sierras. When you consider that GM moved 824,683 examples of its light-duty pickups in 2015, this small run represents 0.08-percent of all Silverado/Sierra production, and GM says it "will monitor the market closely ... and adjust as appropriate moving forward." But that's not the only limitation. The eAssist trucks will only be sold through California dealers. For the Silverado, eAssist can only be optioned on the 1500 Crew Cab 1LT 2WD model, and for the Sierra, the fuel-saving technology is solely available on the 1500 SLT Crew Cab 2WD model with the SLT Premium Plus package. Granted, in terms of the Sierra, that means you get niceties like LED headlights and taillights, Apple CarPlay and Android Auto, Bose premium audio, heated seats and steering wheel, lane keep assist, and more. In the trucks, eAssist combines a small electric motor and 0.45-kWh battery pack with the pickups' 5.3-liter V8. GM estimates total output of 355 horsepower and 383 pound-feet of torque – no more horsepower than the non-eAssist trucks, but three more pound-feet of torque. GM says the eAssist trucks can tow up to 9,400 pounds, and the battery only adds 100 pounds to the trucks' weight. The electric motor provides 13 hp and 44 lb-ft of torque for a boost of acceleration off the line, or during passing. It also allows the engine to run in four-cylinder mode for longer periods of time. eAssist uses regenerative braking to help power onboard electrical systems, and adds start/stop to the powertrain. Finally, the so-equipped trucks have a six-percent improvement in aerodynamics, thanks to a soft tonneau cover and active grille shutters in the front fascia. Great news is, the eAssist option is relatively inexpensive, only costing $500. But good luck getting your hands on one.

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.

GMC Syclone spools up a storm on Jay Leno's Garage

A storm was brewing on American roads in the early 1990s. That's when Detroit's automakers were producing some of the hottest performance trucks ever devised – models like the Ford Lightning, GMC Typhoon, and its flyweight pickup sibling, the GMC Syclone. Jay Leno just happens to have one of the latter in his garage, and took it out to showcase in this latest video segment. The Syclone was an exercise in absurdity, and could not only trounce any other pickup on the road, it could outrun anything else GM made and just about anything else on the road – beating Ferraris and Porsches off the line. In a pickup, for crying out loud. The kicker is that its engine wasn't such a monster, either: under the hood sat a 4.3-liter turbocharged V6 pumping out what would seem by today's standards to be an adequate 280 horsepower and 350 pound-feet of torque. Even the smaller of the EcoBoost V6s available in today's Ford F-150 produces more than that. But in a lightweight, compact pickup, those figures were enough to propel the Syclone to 60 in 4.3 seconds and run the quarter-mile in 13.6 seconds. Long before the dune-jumping Ford F-150 SVT Raptor or even the Viper-powered Dodge Ram SRT-10, GM made fewer than 3,000 Syclones based on the compact Sonoma (sister to the Chevy S-10) and another 4,700 of the Typhoon, which was mechanically similar but more practical (albeit heavier) wagon bodywork from the Jimmy. But as Jay aptly points out, the Syclone was the one you wanted. Scope it out in the ten-minute video clip above.
