Infiniti QX Sport Inspiration Concept fits perfectly in the QX50's shoes

If there was any doubt about whether the Infiniti QX Sport Inspiration Concept is a preview of the next QX50, the official details presented at the 2016 Beijing Motor Show should erase them. The concept is smaller – a lot smaller – than the last QX70. And despite a recent update to the QX50, the brand's midsize crossover is due for a new model. We're basing that statement on dimensions. The QX Sport Inspiration Concept rides on a 110.2-inch wheelbase, and is 181.1 inches long, 74.8 inches wide, and 65 inches high. The last QX50, meanwhile, rides on a 113.4-inch wheelbase, and is 186.8 inches long, 71.0 inches wide, and 62.7 inches high. Ignore the different lengths – the concept's front and rear overhangs are remarkably short and aren't likely to translate to production – but the wheelbase, width, and most importantly the height, present a footprint that's remarkably similar to the QX50. Combine that with our assessment of the QX Sport Inspiration Concept's styling, and it's a virtual certainty that we're looking at the QX50's successor. As we said yesterday, the high beltline, tight greenhouse, long hood, and aggressive headlights are all trademarks of both the QX50 and QX70. Infiniti didn't say what kind of engine is under this concept car's hood (if there even is one – it might just be an engineless shell), but we're almost certain it's something performance-oriented. That would prove true if and when a new production QX50 is unleashed. We're betting the company will opt for the increasingly familiar setup of the new 3.0-liter, twin-turbocharged V6, a seven-speed automatic transmission, and all-wheel drive, like what you can get on the Q50 Red Sport 400 and new Q60. With 300- and 400-horsepower versions of this engine available, it could signal an introduction of a two-tier QX50 lineup. We're getting ahead of ourselves, of course. The QX Sport is still only a concept, but Infiniti's latest information dump at the 2016 Beijing Motor Show serves as even stronger evidence that its CUV lineup will grow back to four vehicles sooner rather than later.

Infiniti replaces Americas chief

The Nissan-Renault alliance has been something of a revolving door for high-level executives of late, and the latest shakeup comes at its luxury unit, Infiniti, where Michael Bartsch (shown above) has been replaced as vice president of its Americas division by Randy Parker. Bartsch had a short tenure – he only took the helm in September 2013. In a press release, Infiniti said he was leaving to "pursue other interests." Bartsch, a veteran of more than 30 years in the auto industry, came to Infiniti from Porsche. Parker comes from within the Nissan empire, formerly heading up the company's sprawling west region, including its marketing, distribution and dealer network. Before that, he served stints at GMAC and General Motors. Bartsch isn't alone in leaving Renault-Nissan recently. Ex-Renault COO Carlos Tavares took the top spot at Peugeot, Infiniti boss Johan de Nysschen left for Cadillac and Nissan executive vice president Andy Palmer took over at Aston Martin.

New details emerge on Inifiniti QX50’s unique new variable-compression engine

Infiniti will release the world's first production variable-compression engine when it releases the 2019 QX50 midsize SUV sometime next year. Now we have some new details on the innovative new engine, which Infiniti is calling VC-T, for Variable Compression Turbo, after the luxury brand offered a prototype test drive. We wrote extensively about the complicated technology underpinning the new engine last year. It's the latest novel development that could represent a range-extender, if you will, for the embattled internal combustion engine in an era when automakers and governments are shifting their focus to electric vehicles. The VC-T is a new inline-four, 2.0-liter that combines the power of a high-performance turbo gasoline engine with the torque and efficiency of an advanced diesel engine, but without the latter's notorious emissions. It features the ability to seamlessly raise or lower the stroke of the pistons in the combustion chamber, depending on the driving conditions it detects and inputs from the driver, to select the best compression ratio—anywhere between 8:1, typical for high-performance engines, and 14:1 for high efficiency. In essence, it delivers the performance of a V6 but is much more efficient, with improved fuel efficiency of between 10 to 15 percent with its best competitors, per Car and Driver. You can view how it works in motion via the video below. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. It's also quieter, more lightweight and compact than V6 engines with comparable power outputs, estimated at 268 horsepower and 288 pound-feet of torque. In a prototype test drive, Car and Driver writes that the engine "felt very conventional" and responsive, with strong and smooth acceleration. "The only indication you have that the compression ratio is changing is from an indicator in the instrument cluster next to the boost gauge." The engine is expected to deliver fuel economy gains of 27 percent in combined city-highway EPA rating over the outgoing QX50, which had a 3.7-liter V6. The 2019 model, fitted with the VC-T, should get about 26 mpg in combined fuel economy, and it will get to 60 mph almost one second faster than its four-cylinder counterparts, Nissan's chief powertrain engineer, Shinichi Kiga, told Automotive News. The VC-T engine is the result of 20 years of development spanning more than 100 prototypes and around 300 patents at Nissan.
