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:

A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

2022 Infiniti QX80 gets an interior update with new, big touchscreen

The 2022 Infiniti QX80 is getting a light interior update in the form of a new touchscreen infotainment system and center stack. If you’ve seen the 2021 Nissan ArmadaÂ’s refreshed interior, then youÂ’ve seen the new QX80Â’s, because they share the same center stack and touchscreen now. This new infotainment system runs on a 12.3-inch high-res screen that sits perched at the top. ItÂ’s capable of wireless Apple CarPlay, but only wired Android Auto. Infiniti says navigation comes standard, too. We liked the new touchscreen in the Armada far more than its outgoing unit, which was ancient technology by the time it was replaced. This new screen is vibrant, features much quicker responses to inputs and is all around a massive step up in tech. YouÂ’ll see the new QX80 also has all the updated controls below the touchscreen, too. We get new dials and buttons (far fewer than before) for the radio and climate controls. Plus, the new layout necessitated a new air vent design. Say goodbye to the dual-screen layout, too, as thereÂ’s no second touchscreen in the lower part of the stack — thatÂ’s a very good thing. Taking up some of that space is a new storage cubby that can be hidden via a piece of wood trim. Flip it open, and youÂ’ll reveal a wireless phone charger and access to a 12-volt outlet.  Besides this interior change, the rest of the 2022 QX80 is carryover. It looks the same from the exterior, and itÂ’s still rocking the 5.6-liter V8 that makes 400 horsepower and 413 pound-feet of torque. Neither pricing nor availability for the updated QX80 were made available today, but donÂ’t expect it to be too much more than the $70,545 base price it enjoys now.
