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:

2014 Mercedes-Benz E-Class lineup shows its freshened face

Mercedes-Benz showed us its redesigned 2014 E-Class more than a month ago, but the Detroit Auto Show finally gave us a chance to see the full family of mid-size luxury cars and wagons in the flesh. Dieter Zetsche introduced the cars, including sedan, coupe, convertible and station wagon, on stage showing the stylish new design direction.
The wagon and sedan versions (shown as the E400 Hybrid above) will go on sale this spring, while the coupe and cabriolet will hit showrooms over the summer. Check our new gallery of live shots for the entire 2014 E-Class lineup, as well as the previously released press release below.

2017 Infiniti QX30 First Drive

If you've heard anything before about this car, the 2017 Infiniti QX30, it probably has to do with its corporate parents, an odd couple if there ever was one. Renault-Nissan, Infiniti's corporate overlords, inked a deal with Mercedes-Benz to share some mechanical components and platforms. That deal put a new, very modern 2.0-liter turbocharged inline-four under the hood of the Q50 and was the genesis of what you're looking at here. What are you looking at here? We drove this car in 2015, when it was called a Q30 – originally it was going to be the lower-riding counterpart to the slightly jacked-up QX30. Then Infiniti decided it'd make more sense to sell all variants of this vehicle as CUVs in the US, so we have three slightly different flavors of the QX30 instead. There's the normal version; the Sport, which is 0.6 inches lower; and the AWD, which is 1.2 inches higher. Infiniti brought us to Seattle to sample the Sport and AWD flavors on a semi-circumnavigation of the Puget Sound. It didn't rain a drop, thanks for asking, and instead was sunny and mild the whole time. It's easy to make the QX30 sound more confusing than it actually is. This is essentially a Mercedes-Benz GLA250 with full exterior styling and partial interior design by Infiniti, built in the UK alongside several other Nissans. The powertrain and chassis, including the optional AWD system, were all "co-developed" with partner Daimler, with final calibration and tuning by Infiniti engineers. Here's another way of explaining it: Infiniti needs an entry-level car to appeal to new premium car shoppers, and the QX30 is the prescription. It's a hatchback that's been given the mildest of CUV treatments and a lot of marketing descriptors. That's because hatchbacks are sales death in America. In Europe, they'll see right through the CUV posturing and realize it's just a hatchback offered in three different suspension heights. Whatever you call it to make it palatable to Americans, it's a useful little vehicle. This car is mechanically identical to the Q30, so there are some things we can gloss over. Both are powered by a transverse-mounted 2.0-liter Mercedes inline-four. It's a turbocharged, direct-injection gasoline engine, and it sure feels like one. It sounds like a rock tumbler full of nickels and runs out of breath at about 5,000 rpm. All versions make 208 hp at 5,500 rpm and 258 lb-ft of torque between 1,200 and 4,400 rpm – more than adequate but less than thrilling.
