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.

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.

2022 Infiniti QX55 marks the company's foray into crossover 'coupes'

Using a formula proven by the major German luxury car companies, Infiniti is now getting in on the crossover "coupe" game. The 2022 Infiniti QX55 takes the QX50 small crossover and adds a fastback roofline for a sportier look. Infiniti says the design makes the QX55 a spiritual successor to the FX crossover of the mid-to-late-2000s and early 2010s. We're not sure if the mechanical bits live up to the rear-drive-based FX chassis, but the low roof and curvy body do share a connection to that old SUV. In fact, the QX55 looks rather striking, and the flowing lines work nicely with the simple, arcing roof. Some other small tweaks to the base styling emphasize the QX55's style focus including a more pronounced grille with larger air intakes surrounding it at the front. At the back, the license plate mount has been moved to the bumper, allowing for prominent Infiniti lettering on the hatch. Additionally, 20-inch wheels are a standard feature on all QX55 models. The rest of the QX55 is basically the same as the QX50. It shares the turbocharged, variable-compression engine making 268 horsepower and 280 pound-feet of torque. It's mated to a CVT and all-wheel-drive, which is standard on all QX55 models. The interior is carry-over with dual infotainment screens and an asymmetric, driver-focused dash design. Like the QX50, it can be slathered in two-tone leather for a very premium feel. The debut vehicle features a bold black and red color combination. The QX55 goes on sale this coming spring. It will be available in three trim levels: Luxe, Essential and Sensory. Pricing hasn't been announced, but expect it to be a bit more costly than the equivalent QX50. For reference, a QX50 Luxe with all-wheel-drive starts around $44,000, and at the other end of the spectrum is the QX50 Sensory with all-wheel-drive starting at around $53,000. Related Video:

Nissan could report first quarterly loss since March 2009

TOKYO — Nissan may report its first quarterly loss in more than a decade on Thursday because of slumping sales, sources familiar with the company said, adding more pressure on efforts to rebuild the company after Carlos Ghosn's ouster. Deteriorating profits underscore the challenges facing Nissan, which is unwinding many of the expansionist strategies championed by ex-Chief Executive Officer and Chairman Ghosn by slashing jobs, production sites and product offerings to save cash and ensure its survival. In addition to slumping sales, production disruptions caused by China's coronavirus outbreak could also drag profits lower. Three senior officials at Japan's No. 2 automaker told Reuters that they anticipate a poor results announcement on Thursday, with one of them calling the figures "dismal". Two of the officials cautioned that there is the possibility of an operating loss, which would be the first quarterly loss since the period ending in March 2009. Nissan said it could not comment on its financial results ahead of its official announcement. The company is likely to report operating profit of 48.6 billion yen ($442.5 million) for the quarter ending in December, less than half the 103 billion yen profit a year ago, according to SmartEstimate's survey of three analysts, who revised their forecasts in January. However, those forecasts were issued before the release of the December vehicle sales figures on Jan. 30, which show third-quarter sales dropped by 11% from the year earlier period, according to Reuters calculations. That is the biggest quarterly slump of its current sales downturn that began two years ago. That sales decline led one auto equities analyst based in Japan to scrap his forecast and also warn that Nissan could post a loss. "It will be a question of whether there will be a profit or a loss. For the quarter, a loss is a possibility," he said, declining to be named as his forecast had not been updated to reflect his latest view. One of the three Nissan officials said there is a risk the automaker may cut its full-year profit forecast of 150 billion yen, which would be an 11-year low. The company announced that forecast in November after an initial 230 billion yen outlook.
