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.

Lexus planning a hydrogen fuel-cell LS by 2017

Toyota's Fuel Cell System will certainly migrate to other vehicles in the carmaker's lineup, but Australian car site Motoring reports that one of the models at the head of the queue is the Lexus LS. According to its sources, the executive barge powered by hydrogen will be released by 2017 and take the top spot in the range, rolling in above the LS Hybrid. We're told that Toyota engineers will find a way to slide two hydrogen tanks into its bodywork with the same general setup as on the Mirai – one under the rear seats and another under the rear parcel shelf. The 150-kW fuel cell stack will be placed under the front seats. Motoring says the resulting sedan and its 220-kW electric motor would come in "at around 2,100 kg," which is 4,620 pounds; that's a ginormous 539 pounds less than the listed curb weight of the current LS Hybrid, and 387 pounds more than the standard LS. Assuming all goes as planned, it would have a range of roughly 238 miles, a few dozens less than the Mirai's range of about 300 miles. It would look slightly different, too, the front end getting larger intakes to cool the power unit. It wouldn't surprise us if Lexus does have a hydrogen LS planned – it would be a statement car, and the company likes making statements, even if few heed them; it has stuck with its LS 600h for the past seven years, yet of the 7,539 LS models sold through the end of November this year, only 61 of them were hybrids. The timing would be intriguing, however; by the time the LS hybrid came out, Lexus had already worked over its filet-and-potatoes models. And if the hydrogen version is going to come in above the $120,440 hybrid, well, that will be a statement indeed.

Lexus RC F GT3 will compete in IMSA SportsCar Championship

Lexus will field its new RC F GT3 in the GT Daytona class of the IMSA SportsCar Championship. GTD is the lowest of the four classes of which the series is comprised, equivalent to the FIA's GT3 class. The team is owned by Trans-Am champion Paul Gentilozzi and his partners, and it's based out of East Lansing, MI. It will contest only a handful of races this season, though the schedule was not announced. The plan is to expand into a "multi-car effort" for 2017. Driving duties will be shared by the previously announced Scott Pruett and the newly signed Sage Karam. Both drivers were recently released from their contracts with Chip Ganassi Racing, for which Pruett drove in NASCAR and Karam in the IndyCar Series. He won the Indy Lights title in 2013 and impressed with a third-place finish last year in Iowa. This year's IMSA SportsCar calendar kicked off this weekend at Daytona, and will head next to Sebring in mid-March, Long Beach in mid-April, Laguna Seca in early May, and Detroit in early June. July will see races at Watkins Glen, Mosport, and Lime Rock, followed by rounds at Road America and VIR in August. The seasons concludes at Austin in September and Road Atlanta at the beginning of October. LEXUS TO COMPETE IN IMSA WEATHERTECH SPORTSCAR CHAMPIONSHIP AND F PERFORMANCE RACING ANNOUNCES SAGE KARAM AS DRIVER TORRANCE, Calif., Jan. 29, 2016 -- Lexus and their F Performance Racing group have reached an agreement with the International Motor Sports Association to campaign the RC F GT3 in the IMSA Weather Tech SportsCar Championship. The agreement gives the Japanese Luxury automaker a presence in the GT Daytona (GTD) class race series through the 2018 season. "We are excited to reach this agreement with IMSA to campaign the RC F GT3 at such a high level. Our hope is to build a strong foundation for the new F Performance Racing organization during 2016 season, seizing the opportunity to develop the team and the race vehicle in anticipation of the multi-car effort during the 2017 season," said Jeff Bracken Group Vice President and General Manager, Lexus division. Additionally, F Performance Racing also announced that Sage Karam will join veteran racer Scott Pruett as drivers for F Performance Racing when the East Lansing, Michigan-based team campaigns the Lexus RC F GT3 for a limited schedule in the 2016 WeatherTech SportsCar Championship. "We have had our eye on Sage for some time," said Paul Gentilozzi, Managing Partner of F Performance Racing.
