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.

FCA-Renault merger faces tall odds delivering on cost-cutting promises

FRANKFURT/DETROIT — Fiat Chrysler Automobiles and Renault promise huge savings from a mega-merger, but such combinations face tall odds because of the industry's long product cycles and problems translating deal blueprints into real world success, industry veterans told Reuters. BMW's 1994 purchase of Rover, and Daimler's 1998 merger with Chrysler both made sense on paper. The companies promised to hike profits by combining vehicle platforms and engine families. Both combinations proved unworkable in reality, and were unwound. Renault and Nissan, which have been in an alliance since 1999 designed to share vehicle components, have only managed to use common vehicle platforms in 35% of Nissan's products despite an original target of 70%, according to Morgan Stanley. FCA and Renault have raised the stakes for themselves by ruling out plant closures. That increases the pressure to achieve more than $5 billion in promised annual savings from pooling procurement and research investments. The two companies have yet to fill in many of the blanks in the merger plan put forward by Fiat Chrysler. Renault's board is expected to act soon to accept the proposal, but that would lead only to a memorandum of understanding to pursue detailed operational and financial plans. A final deal and the legal combination of the two companies could take months to complete if all goes well. Pressure to cut automotive pollution is driving the latest round of consolidation. Automakers are looking at multibillion-dollar bills to develop electric and hybrid cars and cleaner internal combustion engines. Fiat Chrysler and Renault are betting they can design common electric vehicle systems, then sell more of them through their respective brands and dealer networks, cutting the cost per car. Developing all-new electric vehicles can bring more opportunities to share costs from the outset, industry experts said. "With the emergence of connected, autonomous, electric and shared vehicles, carmakers face immediate investments, so new opportunities for sharing costs have emerged," said Elmar Kades, managing director at Alix Partners. However, most electric vehicles lose money. This is a challenge for city car brands in Europe in particular. Both Renault and Fiat rely heavily on this segment for sales.

Basic Continuously Variable Transmission explained with Legos

In recent years, the search for better fuel efficiency and smoother shifting has produced automatic transmissions with double-digit gears. Alternatively, the same quest has boosted the popularity and usage of a different type of automatic transmission without any fixed gears, the continuously variable transmission, or CVT. YouTuber Sariel's Lego Workshop recently took the time to build a CVT demonstration model out of Legos to help explain how they work. Sariel begins by showing the model's input and output shafts that are parallel to each other. Each shaft has a cone attached to it, and they are inversely placed so that the large part of one cone is next to the small part of the other cone. The two cones are connected using a rounded rubber band.  By shifting the rubber band up and down the cones, the machine changes the effective ratio between the cones. So, a 1:4 ratio can be smoothly transitioned to 4:1. No clutch is required to operate the mechanism, and it eliminates hitches or pauses between gear changes. CVTs are also advantageous over 9- or 10-speed automatics in that they are far less complex and weigh less.  To demonstrate how the CVT operates in a vehicle, Sariel used a joke about Top Gear. The original Top Gear is represented by a faster-moving car that has the rubber band around the large part of the cone on the input shaft. Top Gear without former hosts Richard Hammond, Jeremy Clarkson, and James May is represented by a slow-moving car with the rubber band around the large part of the cone on the output shaft.  For an even more detailed explanation of how CVTs work — albeit one that doesn't involve toys — you can click here.
