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.

Nissan, Infiniti issue recall for replacement Takata air bags in older models

Nissan and Infiniti are recalling older vehicles that were repaired after collision damage to address problems with Takata replacement air bag inflators that were potentially installed. The overall campaign population is difficult for Nissan to pin down because the only vehicles impacted would be those that Nissan and Infiniti know to have been serviced with the replacement units in question. Officially, the recalled population numbers just 375, but Nissan says more than 18,000 cars could have the defective parts installed.  Drivers of 2001-2003 Nissan Maximas, 2002-2006 Nissan Sentras, 2007-2012 Nissan Versa Sedans/Hatchbacks, 2002-2003 Infiniti QX4s and 2006-2010 Infiniti M35s/M45s that had their vehicles repaired after a collision or theft should be aware that these deadly replacement parts may have been used.  "The potentially affected inflators may have been installed on vehicles after final remedy repair completion under the vehicle recalls as part of a subsequent theft or collision repair," Nissan's notice said. "Vehicles that received the subject parts prior to December 9, 2016, are not affected as they would have been subsequently included in the final remedy recalls and replaced with a final remedy driver and/or passenger air bag inflator. Nissan has identified 18,422 vehicles that may have had these parts installed during service." The air bag inflators in question were inadvertently shipped to service inventory between December 9, 2016 and November 12, 2021 — after the dangers of Takata's inflator design were known to the industry. Notices are already being mailed; owners will be asked to bring their cars in for inspection, and if defective parts are found, they will be replaced.  Related video: This content is hosted by a third party.

New Infiniti QX crossover: expect a pretty Q60 on stilts

When the doors open at the Beijing Motor Show later this month, Infiniti will have a new concept to show off dubbed the QX Sport Inspiration. It takes the form of a mid-size sport-ute that could preview the next-generation QX70 crossover. The Japanese luxury automaker isn't giving us much to go on aside from the decidedly enigmatic teaser image above. But we're expecting the crossover concept to follow closely along the stylistic lines of the Q60 coupe concept we saw in Detroit earlier this year – albeit in a taller form with more space inside. And that's no bad thing, considering how sexy that two-door show car was. Infiniti tells us to anticipate such design elements as floating A-pillars and wide wheel arches, giving it a forward-looking and aggressive appearance that will foreshadow the company's next generation of crossovers. Watch this space for more as the Chinese auto expo prepares to open its doors on April 25. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.
