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:

Autoblog Unplugged: 2015 Mercedes-Benz GLA45 AMG

Mercedes-Benz's AMG division entered new territory in late 2013 with the launch of the CLA45, an all-wheel-drive sedan (with front-wheel-drive underpinnings) motivated by a turbocharged, four-cylinder engine. But it wasn't any old turbo-four – the boosted 2.0-liter powerplant claimed the title of most powerful production four-cylinder engine. From behind the wheel, we loved its turbo-heavy antics and steer-it-with-the-throttle dynamics. Now, Mercedes offers the GLA-Class – a small crossover based on that CLA architecture. And rather than just leave it alone in GLA250 guise, the AMG folks created the tiny-tough GLA45 high-riding hatch you see here. It's got the same 355-horsepower, 332-pound-feet turbo-four underhood, a seven-speed dual-clutch transmission, and a unique sound that's unlike anything you might expect from a small CUV. That's why we took to some of our favorite backroads to capture another Autoblog Unplugged video with the GLA45. There's no talking, no music, no rizzle-razzle – just shots of the GLA45 driving down our favorite winding roads with nothing but the sweet, throaty sounds of the AMG powerplant. Good luck holding back your giggles when you hear the braaap of a quick gear-change. Mercedes-Benz Crossover Luxury Performance Videos mercedes gla-class mercedes gla45 amg

Smart Cross Connect app changes how ForTwos get used [UPDATE]

UPDATE: The story's been updated with a response from a Smart representative. There are parking spaces, and then there are Fortwo parking spaces. Smart, which is owned by Mercedes-Benz parent Daimler, is looking for a way for its customers to take advantage of the difference. Think of it as a big thing for really small cars. Smart is working on an app for the redesigned Fortwo called Cross Connect that will be available as soon as next month, says Automotive News, citing Smart chief Annette Winkler. The idea is to connect owners of the diminutive two-seat vehicles to, for example, let them tell each other when there's a parking space that's too small for just about any other vehicle but big enough for a Smart. If you think that's a small thing, think again. The Fortwo is 8 feet, 10 inches long. That's almost six feet shorter than a Toyota Prius, which itself isn't exactly a stretch limo. In fact, the length of a Smart Fortwo is just 10 inches longer than the width of a Ford F-150, in case anyone was having misgivings about parking perpendicular in a parallel spot. Parking has become more relevant, and tougher, as more people move to urban centers. For instance, BMW said earlier this month that it would discontinue its DriveNow car-sharing operations in San Francisco because of the challenge of parking vehicles on that city's streets. Other possible amenities with the Cross Connect app including the enabling of personal car sharing as well as information on car washes that offer discounted rates for Smart Fortwo. Yes, there are some out there, apparently, and we salute them. Michael Minielly, a spokesman for Mercedes-Benz, confirmed to Autoblog that the Cross Connect features would be available in November.
