2020 Chevy Silverado HD vs. 2019 Ram, Ford heavy duty trucks: How they compare on paper

Last year was all about the latest in light-duty full-size pickup trucks, so this year, Ram, Ford and Chevy are launching the heavy-duty variants. The first out of the gate is the redesigned 2019 Ram 2500 and 3500 HD, and Ram dropped all the pertinent specs with the reveal. Chevy followed with the new Silverado HD in Chicago, and Ford revealed updates to the Super Duty at the same show. Ford hasn't released details on output, payload capacity, towing capacity or pricing for the updated Super Duty. As such, we'll be comparing the current Super Duty with the all-new Silverado HD and Ram HD. Both Chevy and Ram have revealed full specs for each of their respective trucks, leaving out only pricing, which we've estimated based on the outgoing models. You can see the raw details in the chart below, followed by extra information and analysis. Some things to keep in mind: These specifications cover all versions of the Ram HD, Silverado HD and Super Duty, such as 2500 and 3500 models, and all the way up to F-450. Specifications can vary widely based on engine, drivetrain, cab and bed configurations, so be sure to take a close look at the specific model you're interested in when you get particularly serious about buying. And of course, be sure to check out our car comparison tool if you'd like to look at other trucks on the market. Engines and drivetrains All three of these trucks offer gasoline and diesel engines, but only the Ram has two versions of the diesel. Starting with gas engines, Ram's 6.4-liter V8 has the power advantage with 25 more horsepower than the next-most-potent Super Duty, but the new Silverado HD's 6.6-liter V8 takes the torque crown at 464 pound-feet, nearly 35 more than the other two gas engines. The Ram is also the only one to pair an eight-speed automatic with the gas engine, whereas the Ford and Chevy make do with a six-speed. With diesel engines, horsepower is a weak point for the Ram. The Ram's entry-level turbo 6.7-liter inline-six is the weakest, as the only one with under 900 pound-feet of torque and under 400 horsepower. Even the high-output version only makes 400 horsepower, while the Chevy makes 445 and the Ford 450. But the tables turn with torque, as the Ram makes a best-in-class 1,000 pound-feet followed by the Ford's 935 and the Chevy's 910. Both the Ram and the current Super Duty diesels each get a six-speed automatic, but the new Silverado HD's diesel gets a 10-speed unit.

10 automakers sued over keyless ignitions

Keyless ignition has rapidly proliferated throughout the auto industry to become a fairly normal feature on new cars. It's supposed to offer the convenience of keeping the fob in your pocket and just pressing a button to drive away. However, ten major automakers are now being sued in US District Court over claims that the system is dangerous, Reuters reports. The suit alleges that people are forgetting to shut off the engine, and the lack of an idle timer is the cause for 13 deaths by carbon monoxide poisoning and multiple injuries. The suit currently includes 28 plaintiffs, according to Reuters, but the lawyers are asking for class-action status to potentially add many more. The case goes after a major swath of the industry, including BMW, Daimler, FCA, Ford, General Motors, Honda, Hyundai, Nissan, Toyota, and Volkswagen, plus their related brands like Acura, Infiniti, Mini, and Lexus. In all, over five million vehicles are affected. The assertion here is that people walk away from their vehicle without shutting it off because they believe the engine shuts off automatically. If parked in a garage, carbon monoxide can build up, leading to poisoning. The lawyers claim automakers know this is a problem and also cite 27 complaints to the National Highway Traffic Safety Administration about the issue, according to Reuters. The plaintiffs are asking for an automatic shut-off and damages from the companies. These concerns have come up before, though. Toyota previously faced a lawsuit over a carbon monoxide death after a woman accidentally left her Lexus running. Also earlier this year, GM recalled 64,186 examples of the 2011-2013 Chevrolet Volt because owners weren't shutting them off. The problem resulted in two injuries, and the company released a software update to limit the idling time.

2015 Hennessey VelociRaptor 600 fills an F-150 Raptor-sized void

Ford is rumored to possibly debut a new F-150 Raptor at the upcoming Detroit Auto Show in January, but whether that's the case or not, Hennessey Performance is ready to fill the muscle truck niche now with its latest VelociRaptor 600 Supercharged based on the 2015 F-150. The fantastically named VelociRaptor package has been available on the regular Raptor for the past few years, taking power up to 600 horsepower or more, depending on what the buyer desired. With the latest one, the performance truck is now based on the aluminum-bodied F-150, specifically the FX4 Super Crew model with the 5.0-liter V8. "Having Ford's world-class new truck design, with a weight savings of nearly 700 pounds, our VelociRaptor 600 Supercharged will have an even greater level of performance and driving excitement," said founder John Hennessey in the company's release. The heart of VelociRaptor is the Roots-type supercharger running at 8 psi on the V8. With help from upgraded fuel injectors, a proprietary engine management system and stainless steel exhaust, it boosts grunt from a stock 385 horsepower to over 600 hp. To make sure that power gets to the road, the package also includes 33-inch BFGoodrich mounted on 17-inch Hennessey wheels. For buyers in need of more, the company offers optional parts including an off-road coilover suspension, different front and rear bumpers, a winch, LED light bar and Brembo brakes. Speaking to Autoblog, Hennessey said he feels confident that the latest VelociRaptor could do high-four-second sprints to 60 miles per hour, compared to the outgoing model in the low-five-second range. Prices for the VelociRaptor start at $73,500, which includes the donor F-150, and orders are open now. Actual deliveries should start by March at the latest, according to Hennessey. The company also plans to offer a similar package for EcoBoost F-150s later. Scroll down to read the full announcement about this muscle truck.
