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:

Despite strong profits, GM still fighting flat market share

Looking at the progress General Motors has made since it entered bankruptcy, it's easy to forget that the company still has a long way to go before it's the juggernaut it once was. A recent report from Reuters points out that, while GM is making money, it isn't making any gains in terms of US market share. Quite the opposite, really. Consider this factoid: In 1963, nearly half of the cars sold in the United States were from Chevrolet, Cadillac, Buick, GMC or Pontiac. Now, the company's US market share is stagnant at 17.9 percent. That same number is half of just Chevy's 1963 market share. This is all despite GM going on a binge replacing or updating its models. "Market share increases are not instantaneous," Mark Reuss told Reuters at the 2014 Detroit Auto Show. "We've got a lot of baggage. Don't underestimate what people though of us, or these brands, through these hardships and 30 years." The reasons for the stagnant market share are numerous. Reuters points out that retooling of factories and a focus on limiting incentives are both good things for profit, but not necessarily for market share. There's also the troubling turnover of the brand's marketing department. These issues don't change the fact that Chevrolet has lost 1.4 percent of its market share in two years, and that Cadillac - arguably GM's most improved brand overall - has lost 1.2 percent in the same period. Part of that can be blamed on GM's avoidance of fleet sales in favor of more profitable customer sales. "Our focus has really been on retail and that's where we've got the growth," said Alan Batey, GM's interim global marketing boss. "We want to grow GM and that means growing market share and profits, but it's not at all costs," Reuss said.

Cadillac Elmiraj sedan RWD flagship finally caught testing

While we still have no insight as to it being named Elmiraj, STS or some other permutation of the -TS nomenclature ("LTS" has apparently been registered by GM, as well), new spy shots give us proof positive that Cadillac is indeed hard at work on a rear-wheel-drive flagship model. Spied for the very first time in some north country testing, these shots provide a first look at the upcoming range-topper from Cadillac.
Impressively long and large bodywork ride atop new General Motors' corporate Omega rear-drive architecture here. Heavy cladding over camouflage may discourage finding any details, but the overall, sharp-edged and blocky design is clearly reminiscent of what we've seen on the new CTS and the recently debuted ATS coupe. A strong, wheels-at-each-corner stance helps emphasize the length of this stretched Caddy, and everything about the proportions seem spot-on for a new fullsize flagship for the brand.
It's quite possible that Cadillac will ultimately festoon this large sedan with detailing reminiscent of the original Elmiraj coupe, though thus far we've only seen prototypes wearing four-doors.
