Join Autoblog editors for a full video tour of the 2019 Detroit Auto Show

The 2019 North American International Auto Show might have been a little more quiet than past years, but there were still some pretty major reveals, including the Toyota Supra, new Ford Explorer, Shelby GT500, Subaru WRX STI S209 and Kia Telluride. We also saw some lovely concepts like the Nissan IMs and Lexus LC Convertible. Senior Editor Alex Kierstein, Consumer Editor Jeremy Korzeniewski and Senior Green Editor John Beltz Snyder join me, Associate Editor Reese Counts — with Social Media Manager Michael Dylan Ferrara behind the camera — on a long walk through the show. We discuss cars, poke around the stands, dress a bloody wound and answer your questions in the Facebook comments. For more Detroit coverage, you can check out Autoblog's picks for the best in show, listen to our podcast or look at the best images from all the reveals. Finally, don't forget to watch Editor-in-Chief Greg Migliore hand over our 2019 Technology of the Year award.

Nissan backing off IDx, BladeGlider and Infiniti Eau Rouge amid focus shift

Nissan and Infiniti are officially under the microscope after their presentations at the 2015 Detroit Auto Show focused on the new Titan pickup and Q60 Concept, but lacked any and all mention of allegedly production-bound examples of the Q50 Eau Rouge, IDx and BladeGlider EV concepts. Automotive News reports that the lack of info on the three concept cars, which had previously heralded a more performance-minded Nissan/Infiniti, has signaled a shift in priorities at the Japanese company. Instead of driver-oriented models, emphasis is seemingly being focused more on volume offerings. Nissan was subject to a pair of high-level executive departures last year, with both Andy Palmer and Johan de Nysschen departing for Aston Martin and Cadillac, respectively. Both execs were strong proponents of more driver-oriented offerings, with Palmer championing the compact, rear-drive IDx coupe and de Nysschen backing the high-performance Q50 Eau Rouge. While Palmer has been mum on his former employer's alleged move away from performance, de Nysschen made headlines last month after calling out a Nissan vice president in a Facebook post saying he "heard a rumor that Noboru Tateishi is going to cop-out and shelve the Eau Rouge project now that I'm not there to pressure him," while adding that the VP has "more enthusiasm for 'driver's aid's,' apparently, than 'driver's cars.'" AN reached out to Infiniti, with North American VP Michael Bartsch telling the publication that no decision had been reached about the Eau Rouge and that the company was more focused on rebuilding its core portfolio.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
