2019 Autoblog Technology of the Year finalists revealed

Every fall, we line up a range of new models with the latest and most compelling automotive technology from the past year. We test everything from semi-autonomous systems like Tesla's Autopilot to trick suspension setups like the Multimatic spool-valve shocks on the Chevy Colorado ZR2. We spend months paring down the list to a small group of contenders. After testing, dinner and healthy debate, we tally up the votes and name our winner. For Autoblog's 2019 Technology of the Year Award, our three finalists are the Cadillac CT6 with Super Cruise, the Infiniti QX50 with Variable Compression Turbo and the Mercedes-AMG E 53 with EQ Boost. Super Cruise is an advanced SAE Level 2 semi-autonomous system, though Cadillac (unlike some of its rivals) is reluctant to push that point. Cadillac would like you to think of this as an advanced driver assistance feature rather than a semi-autonomous system. Super Cruise allows completely hands-free highway driving. Thanks to a driver-facing camera, the system forces the driver to keep his or her eyes on the road even if hands are off the wheel. Although the CT6 is being discontinued, look for Super Cruise to make its way to other Cadillacs soon. VC Turbo is a little more complicated. Basically, Infiniti's 2.0-liter turbocharged inline-four can vary the compression ratio on the fly. In general, turbocharged engines are more efficient than naturally-aspirated engines when on boost, but can perform worse at low revs. VC Turbo allows for a best-of-both-worlds situation, increasing the compression at low revs and backing it off once the turbo spools up. The best part is that it does so seamlessly, with only a dash readout letting you know what's going on under the hood. Our third finalist is the EQ Boost 48-volt system in the Mercedes-AMG E 53. Like VC Turbo, EQ Boost does a lot just beneath the surface. Mercedes has developed a new turbocharged 3.0-liter inline-six and paired it with a small electric motor. While the car can't run on electricity alone, the motor helps improve both efficiency and performance, smoothing shifts and filling in low-end torque before the turbos spool up. Think torque fill, similar to a McLaren P1. Who can complain about better fuel economy and more torque? Look for the 48-volt system to make its way into most of the Mercedes-Benz lineup. The winner will be revealed next week on Autoblog, and we'll present the award Jan. 15 at the Detroit Auto Show. Related Video:

Recharge Wrap-up: Cool new Euro VI railroader Unimog, Car2go hearts charity

Mercedes-Benz's mega-cool road-railer Unimog now boasts Euro VI compliance. Used for railroad track maintenance and train shunting work, this diesel-powered Unimog offers about a 90-percent improvement in particulate emissions over the Euro V. The new engine also offers improved efficiency. It provides 231 horsepower, and with eight forward and eight reverse gears, it can travel up to 31 miles per hour in either direction. It also has new in-cabin features that make it easier to use for the driver. Read more about the new road-railer Unimog in the press release below. Carsharing group Car2go has launched a donation feature within its mobile app, called "ride2provide." The feature lets users find "heart cars," which, when used, include a $1 donation to Whole Planet Foundation. The money raised by the ride2provide program goes towards the Whole Planet Foundation's mission of providing microcredit to the poor for creating or expanding home-based businesses. Car2go's ride2provide program started August 4, and runs for 90 days. Learn more in the press release below. China continues to pave the way for more EVs, but some people are still skeptical they'll catch on. Charging station operators will be forgiven some of their electricity fees until 2020, said the National Development and Reform Commission (NDRC). China has already extended tax exemptions on EVs through 2017. The NDRC is also urging local governments to offer subsidies and free charging. Still, the costs involved with installing chargers are keeping many from doing it, and many consumers are hesitant to become early adopters of EVs.

Mercedes warms up the SLC

The Mercedes-Benz SLC moniker was once thought to be revived for the vehicle that became the Mercedes-AMG GT, but the German luxury brand is now rumored to use the name for its upcoming refresh for the SLK. Our spies recently snapped some shots of the updated hardtop convertible testing while not wearing much camouflage. These photos suggest not to expect any significant changes in styling for the refreshed SLK. The lower portion of the front bumper has a single center opening, and the grille gets the latest iteration of Mercedes' single-bar design. The camouflage offers more concealment at the rear, but there's clearly something to hide. The exhausts are better incorporated in the shape, as well. Mercedes is also expected to update the SLK's powertrains with the refresh into the SLC. There could be an AMG Sport version to slot between the regular model and full-bore AMG. Like the C450 AMG Sport, this one might use the brand's 3.0-liter, twin-turbo V6 with 362 horsepower. Related Video:
