2019 Chevy Silverado 1500 vs. 2019 Ram 1500 vs. 2018 Ford F-150: How they compare

The full-size pickup truck market is seriously hot right now. Both Ram and Chevrolet have introduced completely redesigned trucks, the 2019 Ram 1500 and the 2019 Chevy Silverado, and as the companies slowly roll each one out, more and more information comes to light. We've put together this comparison post to help you keep track of all the features and specifications of each of these new models, along with the updated 2018 Ford F-150. Among the stats we'll take a look at are engines, power, fuel economy, trim levels, weight and more. Weight savings Both the 2019 Ram 1500 and 2019 Chevy Silverado 1500 have gone on a diet for the new model year, similar to the one the F-150 went on in 2015. The Silverado is the weight-loss leader, having shed 450 pounds when comparing quad-cab V8 models. The Ram 1500 lost 225 pounds compared to the current truck. Both trucks achieve their weight loss in part due to the use of aluminum parts. On the Silverado, the hood, doors, and tailgate are aluminum, while on the Ram, just the hood and tailgate are aluminum on the body. Compare that to the F-150, which uses aluminum for all exterior body panels for a total weight loss of up to 732 pounds, which makes the aluminum-intensive F-150 the weight-loss leader. View 160 Photos Engines and transmissions There's only a bit of overlap in powertrains on the Ram 1500 and Chevy Silverado. Each has a V8 for the top engine. The Ram's is a 5.7-liter Hemi V8 making 395 horsepower and 410 pound-feet of torque. The Silverado will once again use a 6.2-liter V8 as its range topper with the same 420 horsepower and 460 pound-feet of torque as the current model. Both of these V8s boast some extra fuel saving technology. The Chevy's 6.2-liter (and some 5.3-liters) comes with the company's latest cylinder deactivation system that can shut off any or nearly all of the eight cylinders. The Ram's V8 boasts an optional 48-volt mild-hybrid system that, in addition to likely helping fuel economy, can provide up to 130 pound-feet of torque right off the line. With the Ram, fuel economy sees an improvement of 2 mpg in the city and combined ratings for 17 and 19 respectively. Highway fuel economy improves by 1 mpg to 23 with two-wheel drive and 22 with four-wheel drive. The Silverado's 6.2-liter V8 only improves city fuel economy by 1 mpg to 16, and actually loses 1 mpg on the highway. The new 5.3-liter engine with the fancy cylinder deactivation does see an improvement over the simpler version.

GM recalls 200k Hummer H3s for fire risk

An issue with fires erupting in some Hummers has prompted General Motors and the National Highway Traffic Safety Administration to issue a recall for nearly 200,000 vehicles around the world. The bulk of them are in the United States. According to the first statement (below) obtained by Autoblog from GM, the issue stems from the HVAC system in Hummer H3 models. The connector module for the blower motor has, in certain cases, overheated, melted the surrounding plastic, and started a fire. 42 such cases have been reported, including three instances of occupants citing minor burns. GM confirms that two of those three cases lead to the vehicle being destroyed in the fire, but states that no crashes or fatalities have resulted. The issue affects 196,379 examples of the 2006-10 H3 wagon and the 2009-10 H3T pickup, with 164,993 estimated to be in the United States. In order to fix the issue, dealers are being instructed to replace the relevant parts of the connector and harness. In a second, unrelated campaign, GM is also calling in 50,731 Chevy Spark and Sonic small cars – 45,785 of them in the US – due to a software glitch. In those affected vehicles fitted with the base radio and OnStar system, the audio system may not be able to switch out of turn-by-turn direction mode, causing the display to go blank and all sound to mute – including key safety warnings. In addition, the system may not switch off, draining the battery. GM states that no crashes, injuries, or fatalities have resulted from this issue, and all that dealers will need to do in this case is reflash the software.

The heat could melt the plastic surrounding the connector module, increasing the risk of a fire. Dealers will replace the affected portion of the connector and harness. GM is aware of three reported minor burns and 42 fires but no crashes or fatalities related to this condition. Including Canada, Mexico and exports, the total recall population is 196,379. ### General Motors is recalling 45,785 2014-2015 model year Chevrolet Sparks, and 2015 model year Chevrolet Sonics in the U.S.

GM shows off 'digital vehicle platform' enabling more in-car tech and OTA updates

It appears to have dropped the sobriquet "Global B," but General Motors' new electrical architecture has bowed in drawings and video. This is the "digital vehicle platform" GM president Mark Reuss spoke to Reuters about in 2015, saying it would move a great deal of a vehicle's computer work to the cloud and enable over-the-air updates. Reuss took the microphone for the debut, too, saying, "Our new digital vehicle platform and its eventual successors will underpin all our future innovations across a wide range of technological advancements, including EVs and expanded automated driving." The system will go into production later this year, appearing in dealerships first either on the 2020 Cadillac CT5 or the mid-engined 2020 Chevrolet Corvette. Yes, these are the same electronics cited for delaying the launch of the C8 Corvette over excessive draw, security and getting the more-than-100 computer modules to communicate seamlessly. When Car and Driver asked about that, GM replied with "No comment." Volkswagen's having the same issues with the Mk8 Golf right now, though, so GM isn't alone, and this will be the new normal among OEMs for a while. What's certifiable is that the new architecture is robust enough to handle 4.5 terabytes of data per hour, which is five times what GM's current wiring can handle. And thanks to Ethernet connections of 100 Mbps, 1 Gbs and 10 Gbs, communication within and without the vehicle happens much faster. The advances mean better screen resolutions, better battery management for hybrids and electric vehicles, the capability for over-the-air updates and "functionality upgrades throughout the lifespan of the vehicle." Cadillac's Super Cruise has already been lined up as a leading candidate for constant improvements in the driving assistance suite, a key part of GM's "vision for a world with zero crashes, zero emissions and zero congestion." And whenever GM decides to take the plunge, it will mean a 48-volt electrical system. More than 300 specialists worked on the digital platform, and security was a huge part of the task. We've already heard that GM consulted with Boeing and military contractors on how to prevent hacking. The carmaker has an internal Product Cybersecurity group that reached out to the research community, and created a "bug bounty" program to crowdsource uncovering any flaws.
