Infiniti's variable compression engine in the 2019 QX50 is the first of its kind

The world's first variable compression ratio engine is here, in a production car. That car is the 2019 Infiniti QX50, debuting this week at the Los Angeles Auto Show. The midsize crossover has seen a refresh that has brought it an all-new platform together with new driver assist features, but it's the engine that's the centerpiece here. Nearly everything is continuously variable under the hood of the QX50 – not only the new shift-by-wire XTRONIC CVT. The new VC-Turbo gasoline engine is able to change its compression ratio from 8:1 to 14:1, or anything in between depending of the driving situation; whether there is need for top-end power or turbodiesel-like torque from low revs, or optimized fuel economy. The pistons' reach is continuously adjusted by an electric "Harmonic Drive" motor, which controls a multi-link system, affecting the top-dead-center of the pistons and changing the compression. The engine can also switch between efficiency-maximizing Atkinson cycle and regular combustion cycle, on the go – and there's both multipoint injection and gasoline direct injection employed. The result is 268 horsepower at 5,600 rpm and 280 pound-feet of torque at 4,400 rpm; good figures for a 2.0-liter four-cylinder gasoline engine with a single-scroll turbocharger. Infiniti says that the FWD version's fuel economy of 27 miles per gallon combined is 35-percent better than the previous-generation V6 engine; in AWD guise, it reaches 26 mpg, which is a 30-percent improvement. The new engine is pretty much all-aluminum, but the vaguely magical-sounding "transformative multi-link components" behind the variable compression system are made from high-carbon steel alloy. The engine's multi-link system also enables it to do away with any balancing shafts, and Infiniti compares its smoothness to a V6 rather than a regular four-cylinder. In addition to the aforementioned tech, the VC-Turbo engine has the world's first active engine mount vibration damping system to smoothen its operation even further. Related Video:

Infiniti to offer pair of designer Q50 sedans on Gilt.com

As Infiniti continues to roll out its 2014 Q50, the luxury branch of Nissan is looking to the online luxury purveyors at Gilt to move a couple of special editions of the new luxury sedan. Infiniti has teamed with designers Thom Browne and Zac Posen to create a pair of unique Q50 models, as part of the sale.
The exterior of Browne's car is finished in nearly reflective chrome. Now, we'd love to hold that against him (it's a bit too Bieber), but we think the interior that includes the designer's signature red, white and blue stripes and sterling silver accents is a bit classier. Posen's Q50 is more subdued, with a shades that seem to blend into each other. This ombré look starts in a light silver matte up front before terminating in a glossy, dark gray in back. We know plenty about the appearance of these two cars, but we're kind of in the dark about which powertrain they feature.
Rather than just throw these up on the web and pocket the profits, Infiniti is doing it right. It'll donate proceeds from each car's $75,000 sale price to St. Jude Children's Research Hospital. As for the people that shell out $75K for the unique Q50s? Not only will they get a new vehicle, but they'll be gifted a $10,000 shopping spree on Gilt, along with a "style consultation."

Infiniti readying small crossover for China, is it Juke based?

The small crossover is the superstar segment of the global automotive industry at the moment. With the love that Nissan has for the form with vehicles like the Juke and the Rogue, it should come as no surprise that Infiniti is going to hop into the market as well. However, its luxury CUV is likely going to remain exclusive to China for the time being.
The first hint of the Chinese Infiniti crossover leaked as dark silhouette looking a lot like the Juke, during a brand press conference said to be held in Beijing. It suggested that the model would use the Nissan platform but incorporate unique styling.
Leftlane News speculated that it could be among the company's debuts at the upcoming Beijing Motor Show, but that appears not to be the case. Infiniti spokesperson Kyle Bazemore has confirmed to Autoblog that a "small premium crossover" is under development for China. However, "Details of the vehicle will be announced at a later date. It will not debut at Beijing Motor Show," he said. Also, don't get too excited about the prospects of driving an Infiniti small CUV, because Bazemore says the company has no plans to offer this model elsewhere.
