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:

NHTSA opens investigation into Nissan's handling of airbag recall

In March of 2014, Nissan recalled eight models among its Nissan and Infiniti brands, totaling more than one million vehicles, over faulty occupant classification system software controlling the passenger airbag. The company discovered a variety of factors that would interfere with the system's ability to detect an adult passenger in the shotgun seat, resulting in an illuminated warning on on the dashboard and the passenger airbag not deploying in an accident. Yet 124 complaints submitted to the National Highway Traffic Safety Administration since the recall allege that the dealer-installed fix hasn't actually fixed the problem; some consumers say the problem persists after multiple trips to the dealer. The Detroit News reports that NHTSA is opening an investigation into the matter to determine whether a new recall is needed. The occupant sensor has been a bugbear for Nissan over the past couple of years; a much smaller recall for the issue in 2013 covered five of the eight vehicles that were recalled in 2014, and that earlier recall also continued to generate complaints after the issue had supposedly been fixed. At the same time, the company learned that in two instances there was another twist, where the dashboard warning wasn't illuminated but the passenger airbag still didn't go off in an accident. Nissan isn't alone, though, with airbag recalls on a steep upswing across the industry even before the Takata debacle.

Infiniti Q50 BTCC ready to race

A few months ago, Infiniti announced it would field its Q50 sedan (or a racing derivative thereof) in the British Touring Car Championship, and now the Japanese automaker has revealed the tin-top racer in its final form as it prepares to roll onto the grid. Like the rest of the BTCC field, the Q50 racer is based on the series Next Generation Touring Car (NGTC) regulations. That means it's based on the production model, and not on a control chassis (like the one you'd find in NASCAR) done up to look like the showroom version. It also means a 2.0-liter turbocharged engine driving upwards of 300 horsepower through an Xtrac six-speed sequential gearbox with AP Racing clutch, throttle by wire and the manufacturer's choice of front- or rear-wheel drive, the latter of which we assume Infiniti has chosen for its touring car. Two examples of the Q50 BTCC will be fielded by Infiniti Support Our Paras Racing, a non-profit venture with proceeds (assuming there are any) going towards the British paratroopers' charity. The team is being run by Derek Palmer Sr, whose son Derek Jr will drive one, with the other piloted by Richard Hawken, and injured paratroopers filling out the pit crew and support staff. The Infiniti Q50 BTCC will be showcased on the Dunlop stand at the Autosport International show in Birmingham this weekend. NEW Q50 BTCC LIVERY AT AUTOSPORT INTERNATIONAL SHOW Wednesday, 7 January 2015 The recently announced 'Infiniti Support Our Paras Racing' team, which will contest the Dunlop British Touring Car Championship this season, will unveil a new livery for its two NGTC Infiniti Q50 race cars at the Autosport International Show in Birmingham later this week. The new livery on the Q50, being displayed on the Dunlop stand, has been designed by Infiniti's own design team in Paddington London, further enhancing the ongoing partnership of Infiniti with the Mallory Park-based team, which will employ injured ex-Paratroopers to prepare both race cars. Simon Cox, Infiniti Design Director from Infiniti Design London, said "The new Q50 race car livery was developed to contrast against the traditional branding schemes normally associated with the BTCC grid. However, it still retains a high level of visibility, reflecting both the dynamic qualities of the Infiniti Brand along with the performance and striking contours of the Q50 road car.
