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:

Cadillac CT6 hybrid likely to appear in Shanghai

Cadillac is poised to reveal a hybrid version of the CT6 sedan later this month at the Shanghai Motor Show. Rumors have swirled of the sedan's pending reveal, and General Motors product chief Mark Reuss reportedly confirmed its existence last fall during an investor conference. On Wednesday, Reuss again said that GM is working on the hybrid CT6, and when asked by Autoblog, he hinted at the pending debut. "We've really got to wait until we finish rounding out the portfolio," he said. "The Shanghai show is where you should look for all of it. So stay tuned." A Cadillac spokesman declined to comment, but confirmed "we will add variants." The brand has already announced two V6 engines and is looking to expand the line. Reuss also said GM has considered a V-Series model for the CT6, but it's focusing on launching the four-cylinder and V6-powered sedans first and promoting V-Series versions of the CTS and ATS that arrive this year. "The [CT6] architecture is certainly capable of doing it," he said. "The question is who's going to buy the CT6? What kind of person? And do we need a V-Series off of that is the question we haven't answered yet. It's certainly capable of doing it ... we've certainly thought about it." Details of the hybrid powertrain aren't known, but it could use plug-in technology. Chevrolet announced the 2016 Malibu will get a hybrid model that employs electric powertrain features from the new generation of the Volt. For the CT6, electric-vehicle technologies would likely be used to extend range and aid the performance of the conventional engine. Related Video:

2015 Cadillac ATS Coupe First Drive

Save for a few years of its century-plus existence, Cadillac has offered its unique brand of American elegance in two-door, fixed-roof bodystyles. Most of these cars were big, floaty barges, of course, though its most recent offering was the wedge-shaped CTS Coupe. But whereas the CTS Coupe was a statement car – angular and severe, with somewhat limited appeal except to design snobs and provocateurs – the ATS Coupe represents a return to form for Cadillac, with a proper three-box (engine-cabin-trunk) body and a slightly lower price point that should broaden its appeal among a larger swath of the market. Generally speaking, the 2015 ATS Coupe is a two-door version of the sporty ATS Sedan, though, surprisingly, the only common exterior components are the hood, headlamps, and sundry trim pieces on the front fascia (which features a slightly larger grille, a wider lower air intake, and the redesigned, laurel-less Cadillac crest). Even the mirrors are different. The body stretches 0.8 inches in length and 1.4 inches in width, the roof is 1.1 inches lower and the rear windscreen slopes at a flatter, sleeker angle. Interestingly, the windowsills are actually quite a bit lower, further slimming the car. Thanks to its 0.8-inch wider front and rear wheel tracks as well as more tumblehome in the C-pillar area, the coupe sits lower and looks more planted than the ATS sedan, particularly from the rear three-quarter view. Filling the wheel wells is a family of slick 18x8-inch wheels, with 18x9-inchers coming on the rear axle of performance models. Even if all those changes haven't resulted in a wholly new look the way the CTS Coupe departs from its sedan progeny, the ATS two-door is a truly beautiful car that looks considerably better on the road than on a show stand. And for that, Cadillac deserves mighty praise. The ATS two-door is a truly beautiful car that looks considerably better on the road than on a show stand. It is a proper coupe, of course, and as such is saddled with the expected limitations that accompany modern two-door packaging, notably rear seat access and limited rear headroom. Since the floorpan is common to both bodystyles, rear legroom is the same as the sedan's, though headroom shrinks a considerable 1.8 inches, making it hard for even average-sized adults to sit back there without their heads touching the window glass.
