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.

Nissan considering 200-mile Leaf to take on Chevy Bolt?

With 30,200 units sold, the Nissan Leaf posted its best year ever in the US in 2014. However, Nissan needs to keep looking over its shoulder because the Chevrolet Bolt Concept from the 2015 Detroit Auto Show clearly has success EV in its sights. Chevy claims that for roughly the same price (after incentives) as a Leaf, the future Bolt could offer a 200-mile range. Although, evidence continues to mount that the Japanese brand is hard at work on its next-gen electric hatchback capable of significantly longer driving distances. According to TheDetroitBureau.com, the next Leaf will reportedly debut in about two years and will be offered in a high-output version with 200 miles or more of range. It will all be possible thanks to new lithium-ion batteries with lower weight and higher power density. If accurate, the changes would more than double the model's current EPA-estimated 84-mile range and put the hatchback on sale at roughly the same time as the Bolt's debut, if it happens. "We want to be competitive," said Nissan CEO Carlos Ghosn to TheDetroitBureau.com during the Detroit Auto Show. "It may have even more range." In another speech, he also predicted that the company's EVs would become even more affordable. The statements are hardly a surprise from the company boss. Ghosn is a big proponent of electric power over other zero-emissions alternatives because it is cheaper overall, among other reasons. The latest speculation about battery innovations from the next Leaf actually echoes earlier leaks about the car. Ghosn suggested during a Japanese TV interview that the range could double for the new generation, and an unnamed engineer believed that 250 miles of driving was at least possible.

Nissan demonstrates GT-R LM Nismo's radical aero

Nissan took a radical approach in designing its GT-R LM Nismo, turning the usual LMP1 form on its head to create a rather unusual prototype. So why did it take such a drastic approach? In a word: aero. In designing a front-engined, front-drive Le Mans prototype, Nissan was able to free itself from many of the restrictions placed on aerodynamic development. So while the likes of Toyota, Audi and Porsche struggle to create as much downforce as the regulations will allow at the rear of their cars, Nissan is finding boatloads more at the front. It's an innovative approach if we've ever seen one, and you can see and hear the team explain how it all works in this latest video clip above.
