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:

Infiniti takes to Facebook to explain model names, mentions 550-hp flagship

Infiniti caused quite a stir this week when it announced that it would be changing its vehicle names so that all of its cars start with Q and all of its crossovers and SUVs start with QX. Many displeased fans and owners took to social media to voice their opinions, and Johan de Nysschen, the new Infiniti boss, responded today with a Facebook post of his own.
In the note, de Nysschen talks about the challenge of product expansions with alphanumeric names that allow for flexibility without encroaching on the trademarked names of other automakers, although we're sure de Nysschen's former colleagues at Audi aren't looking forward to a Q30 or Q50. He also says that as Infiniti grows to become a global brand, the new naming structure - which closely mimics Volvo - is also designed to reduce confusion (just don't tell that to current owners). One thing that de Nysschen assured wouldn't happen is a confusing "X" added to the end of all-wheel-drive model names that would result in names like the Q60X or, even worse, the QX50X.
While we are not looking forward to relearning Infiniti's product lineup, de Nysschen has given us something to look forward to courtesy of a new performance sedan. From the brief explanation of this car, which was used as a key example in explaining the validity of the new names, we learned that the new model will be a performance version of what is now the M sedan, and it will be powered by a "charged induction" 3.0-liter V6 producing more than 550 horsepower. The M's name will become the Q70, but as of right now, it isn't clear if this will be an IPL model or something else.
