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.

The next steps automakers could take after sales drop again in April

DETROIT (Reuters) - Major automakers on Tuesday posted declines in U.S. new vehicle sales for April in a sign the long boom cycle that lifted the American auto industry to record sales last year is losing steam, sending carmaker stocks down. The drop in sales versus April 2016 came on the heels of a disappointing March, which automakers had shrugged off as just a bad month. But two straight weak months has heightened Wall Street worries the cyclical industry is on a downward swing after a nearly uninterrupted boom since the Great Recession's end in 2010. Auto sales were a drag on U.S. first-quarter gross domestic product, with the economy growing at an annual rate of just 0.7 percent according to an advance estimate published by the Commerce Department last Friday. Excluding the auto sector the GDP growth rate would have been 1.2 percent. Industry consultant Autodata put the industry's seasonally adjusted annualized rate of sales at 16.88 million units for April, below the average of 17.2 million units predicted by analysts polled by Reuters. General Motors Co shares fell 2.9 percent while Ford Motor Co slid 4.3 percent and Fiat Chrysler Automobiles NV's U.S.-traded shares tumbled 4.2 percent. The U.S. auto industry faces multiple challenges. Sales are slipping and vehicle inventory levels have risen even as carmakers have hiked discounts to lure customers. A flood of used vehicles from the boom cycle are increasingly competing with new cars. The question for automakers: How much and for how long to curtail production this summer, which will result in worker layoffs? To bring down stocks of unsold vehicles, the Detroit automakers need to cut production, and offer more discounts without creating "an incentives war," said Mark Wakefield, head of the North American automotive practice for AlixPartners in Southfield, Michigan. "We see multiple weeks (of production) being taken out on the car side," he said, "and some softness on the truck side." Rival automakers will be watching each other to see if one is cutting prices to gain market share from another, he said, instead of just clearing inventory. INVESTORS DIGEST BAD NEWS Just last week GM reported a record first-quarter profit, but that had almost zero impact on the automaker's stock. The iconic carmaker, whose own interest was once conflated with that of America's, has slipped behind luxury carmaker Tesla Inc in terms of valuation.

These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.
