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:

Mercedes-Benz B-Class Electric Drive gets official US launch

It's finally time to plug in the first production Mercedes-Benz-branded electric vehicle in the US. The Daimler division, which also sells a few of its battery-electric Smart ForTwo vehicles here in the states, has officially launched sales of the Mercedes-Benz B-Class ED. Even better, the US will be the first market in the world to give the general public access to the new plug-in. As with many other EV debuts, the flyover states will have to wait a bit. Mercedes-Benz is only selling the B-Class ED in 10 coastal states, including California, Oregon, New York, New Jersey, Maryland and Maine, and hasn't said anything about when a broader release might happen. Earlier this month, the US Department of Energy rated the B-Class electric with an 87-mile single-charge range, which is comparable to that of the Nissan Leaf and BMW i3. The other shoe dropped, though, when it was revealed that the model has an 84 miles per gallon equivalent rating, which is about 30 percent less then both of those other EVs. The culprit for the model, which puts out 177 horsepower and has a base price of $41,150, is its heavier curb weight. Check out Autoblog's "First Drive" impressions here.

2016 Mercedes-Benz GLE-Class First Drive

The name has changed, but the song remains, well, mostly the same. The updated 2016 Mercedes-Benz GLE-Class (nee M-Class) is all about refinement and a new attitude. Further up the range things have gone all Daft Punk – harder, better, faster, stronger. Merc's bread-and-butter SUV was last revamped in 2012, and this redesign essentially grafts the company's new corporate face and tail onto the vehicle formerly known as ML. A two-bar grille runs the expanse between stretched headlights. Above them sits a more sculpted hood with dual power lines. Below all that is a bumper with three large intakes, similar to Mercedes' sedans. The sides are untouched, but in back you'll find a new LED taillight design and trapezoidal tailpipe finishers. On the AMG Line trim pictured here, the elements rendered in chrome on the base model – like the central guard in front and diffuser panel in back – are done in black. The interior changes start with the driver staring at a new three-spoke steering wheel front-and-center, and a larger, eight-inch infotainment display on the right. That screen stands proud of the instrument panel, with two vents flanking it to remind you this isn't a clean redesign. Compare that to the freestanding tablet look, like on the C-Class, and you'll get what we're talking about. Below the big screen are the infotainment and HVAC controls that we've been looking at since 2012. The center stack newness ends there. Below the big screen are the infotainment and HVAC controls that we've been looking at since 2012. They feel really old now – perhaps because these same dials and buttons were in the E-Class sedan in mid-2009. The controls on the console, however, are overhauled, with the glossy, swoosh-shaped COMAND controller taking up residence next to the driver's arm. Beside that are a few buttons controlling functions like ride height and hill descent control, as well as the new Dynamic Select knob. This dial controls up to six driving modes. There's Comfort, Sport, Slippery, Off-Road Light, and Individual. Buyers who opt for the Off-Road Package will get a sixth mode, Off-Road+. Mercedes expects only 10 percent of GLE customers will want that capability. Every GLE comes with the basic five-setting Dynamic Select knob, no matter which of the five engines are under the hood. Here's where things get tricky, so we'll list the details for the sake of clarity.
