Diesel details: Comparing Ram 1500 EcoDiesel, Chevy Silverado Duramax, Ford F-150 Powerstroke

With specifications for the 2019 Ford F-150 Power Stroke diesel already out, and the details on the 2020 Ram 1500 EcoDiesel and Chevy Silverado Duramax (and its GMC Sierra twin) trickling out, we felt it was a good time to start comparing the full-size trucks' light-duty diesels. Bear in mind, we've only driven one of these new diesel trucks, so we'll be sticking to numbers for now. Some numbers haven't been announced yet, either, but stay tuned, because we'll be updating this post with additional specifications as they become available. And if you want to compare any other versions of these trucks with other vehicles, be sure to check out our comparison tool. Now let's start comparing, starting with our big chart of numbers below. As we can plainly see, these trucks are quite closely matched. Each one has six cylinders, a displacement of 3.0 liters and a turbocharger to boost it. The output of each is somewhat close, too. The Ram 1500 EcoDiesel is the torque king at 480 pound-feet, 20 more than the GM trucks and 40 more than the Ford. The GM trucks win on power, though, with 277 ponies, 17 more than the Ram, and 27 more than the Ford. GM does report that you get their trucks' peak 460 pound-feet of torque from 1,500 rpm to 3,000 rpm, whereas the others only report peak torque at a particular point in the rev band, but all of these trucks should have wide, flat torque curves as you would expect from modern turbodiesels. 2020 Ram 1500 EcoDiesel View 8 Photos Engine output is only one part of the truck performance equation. We also have towing and payload capacity, as well as fuel economy. With towing, the Ram 1500 is the current leader with a maximum capacity of 12,560 pounds. That tops the Ford F-150's 11,400-pound tow rating by well over 1,000 pounds. The F-150 can carry 2,020 pounds in its bed, but we don't know yet whether that's better or worse than the Ram or the GM trucks. We also don't have numbers for the GM trucks' towing capacities. View 9 Photos As for fuel economy, the Ford F-150 manages a thoroughly impressive 22 mpg in the city and 30 on the highway with two-wheel drive. Choosing four-wheel drive drops those numbers to 20 and 25 respectively. The fuel economy numbers for the Ram, Chevy and GMC haven't been revealed yet, but for some comparison, we can look at the old Ram EcoDiesel. That truck's best fuel economy was 20 in the city and 27 on the highway with two-wheel drive.

2016 Chevrolet Malibu Hybrid Quick Spin [w/video]

If a Chevy Volt is like a hybrid that prefers its electric motor, then the new Malibu hybrid is like a Volt you never have to plug in. That's partly because you can't plug it in, but more because the Volt and the gas-electric Malibu share a lot of major components. Since we happen to like the newly refined Volt, that's good news for the larger family sedan. The shared parts include the blended braking system, A/C compressor, the auxiliary power module, and most of the hybrid transaxle (what you might call a fancy electro-transmission). In the Malibu, the electric motors use neodymium magnets for efficiency and power, while the Volt has weaker ferrite magnets to reduce drag, and the Volt also gets an extra clutch to lock out the engine. The two use different batteries, with their size, power capabilities, and chemistry suited to the task for each vehicle. Unlike most of the midsized sedan leaders, the Malibu has never had a full hybrid option. For a few years in the last generation, Chevy offered the Malibu Eco with a version of GM's eAssist mild-hybrid system, which featured a small motor-generator in place of an alternator hooked up to a bigger battery that could harvest energy during deceleration and add some back in when you hit the throttle; it also brought engine stop-start functionality to save a little more fuel. But it saved only a little fuel, so eAssist was nixed in favor of a more efficient four-cylinder with a standalone stop-start system. Driving Notes Mode switches between gas and electric are just as smooth as in the Volt. No shudder or weirdness in the throttle. It drives as much like a gas-only car as any midsized hybrid does. The blended braking system is also noticeably well sorted. There's no deadness in the pedal, no touchiness, and no artificial, wooden feeling when you step through the regen portion of its travel. There's nothing abrupt or jarring about any of the experience, and the Malibu's baked-in quietness helps to deal with noise from the somewhat coarse 1.8-liter gas engine. Engine startup and shutdown are noisy from outside, but much less noticeable from within. The 2016 Malibu is larger yet lighter. The hybrid weighs about 125 pounds more than a comparably equipped 1.5T. You don't notice the extra weight, but there is some space eaten out of the trunk by the battery.

GM 8-speed transmission lawsuit granted class action certification

A story on Autoblog about potentially faulty 8-speed automatic transmissions from General Motors in 2019 has, as of the day this was published, 166 comments, mostly from owners of cars and trucks who say they are experiencing "a hesitation, followed by a significant shake, shudder, jerk, clunk, or 'hard shift' when the vehicle's automatic transmission changes gears." At the time, lawyers were seeking statewide classes in at least six states. As of today, the Detroit Free Press reports that a judge has granted class action status to a lawsuit brought by 39 plaintiffs across 26 states covering the transmission issue. The lawsuit specifically applies to vehicles that are equipped with GM's 8L90 or 8L45 8-speed automatic transmissions made between 2015 and March 1, 2019. Both of these transmissions are similar units, the 8L45 being slightly lighter version used in fewer vehicles than the beefier 8L90, and are designed for front-engine, rear- or all-wheel drive applications. The lawsuit alleges that the erratic transmission behavior makes some vehicles unsafe to drive. Ted Leopold, partner at Cohen Milstein and the court-appointed lead counsel for the case, said in a statement, "General Motors knowingly sold over 800,000 eight-speed transmission vehicles, which they knew to be defective for years, and yet made the business decision not to tell its customers before purchase." He added, "Dealers were directed to tell the customers that harsh shifts were ‘normal' or ‘characteristic.Â’ Such decision making is both highly irresponsible and emblematic of what GM believes it can get away with." The vehicles included in the court order with potentially faulty transmissions includes: 2015-2019 Chevrolet Silverado 2017-2019 Chevrolet Colorado 2015-2019 Chevrolet Corvette 2016-2019 Chevrolet Camaro 2015-2019 Cadillac Escalade and Escalade ESV 2016-2019 Cadillac ATS, ATS-V, CTS, CT6, and CTS-V 2015-2019 GMC Sierra, Yukon, Yukon XL, and Yukon Denali XL 2017-2019 GMC Canyon Some additional details of the lawsuit can be found at the Cohen Milstein site, including claims that "since 2015, GM has issued thirteen versions of a “technical service bulletin,” or “TSB,” related to this shifting issue alone." The statement from Cohen Milstein says that a "second action regarding GM vehicles with 8L transmissions is also underway in Battle v. General Motors, LLC, 2:22-cv-108783.
