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:

2016 Cadillac ATS-V First Drive [w/video]

If you get hot and bothered for hot-rodded sedans and coupes, you probably know that Germans have long dominated that cutthroat scene. For years, the Audi RS/BMW M/Mercedes-AMG triumvirate has ruled the microcosm of grunty, mid-level luxury cars. But a funny thing happened when Cadillac's first V car hit the market in 2004. Since the CTS-V crashed the high horsepower party, German tuning houses started thinking less about the "Daddy's Caddy" stereotypes and more about the next imminent threat – in this case, the inevitable high-horsepower spinoff of the smaller, nimbler Cadillac ATS. The standard ATS' defense against the German triad hasn't been triumphant so far (GM's Michigan plant was idled for three weeks in 2014 due to excess inventory), but the souped-up 2016 Cadillac ATS-V presents a fresh bid to put the Teutonic competition on alert. The ATS-V's flared bodywork and quad exhaust pipes offer bits of visual shock and awe, but significant hardware upgrades back up the go-fast looks. Front and center is a twin-turbocharged, 3.6-liter V6 with reworked internals including a charge-air cooler, titanium connecting rods, and titanium-aluminide turbines. The new engine produces 464 horsepower and 445 pound-feet of torque, up a staggering 262 hp and 173 lb-ft compared to a base, four-cylinder ATS. Those output figures eclipse the BMW M3/M4 (425 hp, 406 lb-ft) and Audi RS5 (450 hp, 317 lb-ft), but lag slightly behind the V8-powered Mercedes-AMG C63 (476 hp, 479 lb-ft), and more so the C63 S (503 hp, 516 lb-ft). The chassis benefits from several structural braces, most notably a shear panel intended to boost front-end stiffness. Extra poundage from the add-ons are minimized through lighter-weight materials – in the case of the shear panel, stamped aluminum. Cadillac says though it intended to make the ATS the quickest car in its segment (stated 0-60 mph times between 3.8 and 3.9 second virtually match the BMW M4 and Mercedes-AMG C63 S' 3.9 figure), the development team says they also focused on subjective qualities like turn-in quickness and steering response. As such, toe links have been replaced with ball joints, mounts have been retuned, and reworked magnetic damping offer greater responsiveness. Six suspension bushings have been stiffened and ten have been completely redesigned, and the Performance Traction Management system that tames beasts like the Corvette Z06 and Camaro ZL1 also helps lay down power in the ATS-V.

2017 Cadillac CT6 Plug-in Hybrid is the most efficient and torquey CT6 of all

Cadillac is returning to the hybrid game after discontinuing the ill-fated ELR, this time with an existing car and a new drivetrain. The company has taken its CT6 flagship and given it a turbocharged 2.0-liter four-cylinder, a pair of motors, and a big battery pack. The result of this combination is a CT6 that manages a rating of 65 MPGe, can go 30 miles on a full electric charge or 400 miles combined with the engine. The powertrain produces 335 horsepower and 432 lb-ft of torque. That's the same amount of power as the 3.6-liter V6 CT6, and more torque than that engine or the twin-turbo 3.0-liter V6. Cadillac claims the CT6 plug-in is capable of hitting 60 miles per hour in 5.2 seconds and reaching a top speed of 150 mph. The green and grunty CT6 plug-in will be available this coming spring, and it will have a premium price of $76,090. Cadillac says that its equipment list is comparable to the CT6 Premium Luxury trim level, which starts at $64,590 with the 3.6-liter V6, and $68,590 with the twin-turbo V6. However, in addition to the hybrid powertrain, Cadillac throws in a number of features that are options on the conventional gasoline models. To get the hybrid's rear seat infotainment system and enhanced night vision, a buyer would have to add $5,800 in option packages. That still leaves the twin-turbo model $1,700 shy of the hybrid, but that's not a terrible trade for the option of fuel-free driving for at least some of the time.
