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:

Twin-turbo Cadillac CTS coming

New Mercedes E-Class nearly exposed, may be Maybach

The all-new Mercedes-Benz E-Class is marching closer and closer to production, with a new round of spy photos giving us our best look yet at the S-Class-inspired looks of the German brand's executive luxury car. There really is very little camouflage this time around – what's there looks more like the kind of plastic wrapping you'd see on a freshly imported vehicle at the port. In front, we can see the new E will wear similar LED accents to the S- and C-Class. The E-Class' big and little brothers also inspired the tail of the new model, where we can see slightly disguised, vertically oriented LED taillights. Prominent, enclosed exhausts are very similar to what we saw in our spy shots of the Mercedes-Maybach E-Class. Aside from the exhausts, this particular car also wears the same blingy wheels as the range-topping tester we spied last August. The thick-rimmed, multi-spoke design isn't the only giveaway to this car's luxurious intentions, though. Our last Maybach sighting showed a car completely covered in camo, making it difficult to tell just how large the rear doors are relative to the car we're seeing today. Instead of the doors, though, we suggest you look at the windows. Like the August spy photos, this prototype features tinted rear glass, which could perhaps indicate that we're looking at yet another example the second Mercedes-Maybach model. So is this yet another Maybach E-Class? We're leaning towards yes. The size of the back doors – and the rear quarter window, in particular – is close enough to what we saw last month, and the presence of tinted glass, the same exhausts, and the same wheels can't be discounted either.
