2018 Autoblog Technology of the Year finalists

After months of prepping and several days of testing, we narrowed the field for Autoblog's 2018 Tech of the Year award to the Nissan Rogue with ProPilot Assist semi-autonomous driving system, the Lexus LC 500h and its new hybrid powertrain, and the Chevy Colorado ZR2 and its trick Multimatic spool-valve off-road shocks. Three very different cars with very different technologies duking it out for the award. Look for news of our winner at the 2018 Detroit Auto Show. We hand out this award every year to the technology or feature that we feel moves the bar forward for the automotive industry. Read more here on how our testing process works. We discuss, debate and count up score sheets, judging each vehicle and technology on a few different criteria. Is its purpose noteworthy? Does it work well? Does it advance the industry? The Nissan Rogue with ProPilot Assist was actually a prototype, as the technology will first debut in the 2018 Nissan Leaf. Still, we're here to test the tech and not the car. ProPilot Assist combines adaptive cruise control system combined with lane-keeping assistance. The system uses sonar, radar and a number of cameras for some light semi-autonomous driving and enhanced safety. While these systems aren't new individually, Nissan's system is affordable, intuitive, and coming to a mainstream product — democratizing the tech in a novel way, if you will. That's why it's here. The Lexus LC 500h uses a new powertrain that Lexus has dubbed the Multi-Stage Hybrid System. Basically it combines two types of transmissions — a CVT and a four-speed automatic — in a single unit mated to a naturally aspirated V6. That's complex and unorthodox technology, and Lexus engineered it to give drivers the efficiency of a CVT without sacrificing driving enjoyment. The package is subtle, working in the background to create a nearly seamless driving experience. It's engaging in a way most other hybrids can only dream of. The fact that it's wrapped in such gorgeous sheetmetal only makes things better. The Multimatic spool valve shocks in the Chevy Colorado ZR2 might seem low-tech compared to ProPilot Assist and the Lexus Multi-Stage Hybrid, but they represent a completely novel application of a technology that several years ago was so expensive that it was reserved for top-tier race cars. Like the LC 500h, these shocks really change your perception of how a vehicle like this should drive.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).

2016 Chevy Silverado unveiled in full at Texas State Fair

It's State Fair time down in the Lonestar State, which means a lot of things to a lot of Texans: rodeos, cook-offs, country music concerts, big belt buckles, and even bigger hats. But it also means new trucks. Ford used the occasion this year to roll out its new F-Series Super Duty pickups, but the Blue Oval won't have the show all to itself as Chevy is also on hand to reveal in full its latest updates to the Silverado. The Bowtie brand gave us our first glimpse at its updated 1500-series pickup back in July, but has now revealed the revised truck in full – and not just in Z71 spec, either. Buyers will be able to choose between WT, LS, LT, LTZ, and High Country trim levels – to say nothing of the various cab, box, and powertrain configurations. The top three get all-LED exterior lighting. And while the Z71 adopts the color-keyed trim we saw previously, other models like the LT, LTZ, and (to a lesser extent) the top-of-the-line High Country still bring the chrome for those who want it. Whichever the model, the new Silverado boasts a more muscular-looking front-end and a more sculpted hood. Inside, the new Silverado gets an optional MyLink system with Apple CarPlay and Android Auto support. The revised truck also benefits from added safety technology and convenience features. Engine options include a 4.3-liter V6 with 285 horsepower and 305 pound-feet of torque, a 5.3-liter V8 with 355 hp and 383 lb-ft, and a 6.2-liter V8 with 420 hp and 460 lb-ft. The news when it comes to powertrains is that the eight-speed automatic launched last year on the larger V8 is now being offered on the smaller 5.3 as well. 2016 Silverado: The New Face of Strong 2016 Silverado designed to build on Chevrolet's truck momentum 2015-09-24 - Bolder, more muscular look reflects Silverado strength, dependability - Expanded use of 8-speed transmissions; additional safety technologies - Available support for Apple CarPlay and Android Auto DALLAS – The new 2016 Chevrolet Silverado 1500 brings muscular designs and new customer-focused technologies to the most dependable, longest-lasting family of full-size pickups on the road. The new Silverados make their public debut today at the State Fair of Texas in Dallas. "The new 2016 Silverado will build on the Chevy truck legacy of dependability," said Sandor Piszar, marketing director for Chevrolet trucks.
