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.

Infiniti QX60 Monograph previews a handsome next-gen three-row crossover

Infiniti has pulled the sheet off its QX60 Monograph — a styling exercise meant to preview the forthcoming production replacement for its three-row crossover. Infiniti insists that while this is not the production QX60 replacement, it is close enough to not merely be labeled a "concept." Whatever Infiniti wants to call it, it's impressive. This slick design blends elements of the original Infiniti FX line with some of the luxury brand's more recent artistic direction (see: the big, fat grille) and perhaps a little dose of European flavor; we'd be lying if we said there wasn't some Jaguar F-Pace evident in that profile.  "More than a design study or concept, a 'Monograph' provides a tangible insight into how Infiniti plans to transform a future model. The QX60 Monograph previews some of the proportions and design elements that will adorn the brandÂ’s future three-row SUV, " Infiniti said in the QX60's official announcement. "We commenced the design of the Monograph knowing this was an opportune time to start a discussion about where we are planning to take the QX60 in the future," said Alfonso Albaisa, senior vice president, Global Design, Nissan Motor Co. Ltd.  "In crafting this Monograph, we wanted to change the tonality of the QX60 and transform the nameplate from a sculptural and architectural point of view. We raised the visual center of gravity, giving it a strong, straight shoulder line that carries through to the hood, with a higher, more prominent grille, and longer-looking cabin to deliver a sense of muscularity and a commanding presence," Albaisa said. Every element of the QX60 Monograph's exterior was designed deliberately to convey that image, from the heat-sink-inspired shape of the headlamps to the slick, well-integrated segments of the rear lighting signature, which blends into a single wrap-around element when not illuminated.  As close to production-ready as this QX60 Monograph might be, there are some obvious signs that there's still work yet to be done. As you'll note, there's not a single shot of this crossover's interior, and that's because it doesn't have one yet. Infiniti knows it can't afford to fumble a new launch, especially of a crossover, so we have fairly high expectations for its cabin, especially since Infiniti has been known to produce some top-notch interiors when it tries. Look for the real-deal next-generation QX60 to be shown sometime in 2021. 

Infiniti will reinvent its models, tech and design language as part of reboot

Infiniti raised more than a few eyebrows when it announced plans to follow a strategy it described as Nissan-Plus. Although this term suggests the brand's image will be dangerously watered down, its chief executive stressed its flag will remain firmly planted in the luxury car segment as he outlined what to expect in the coming years. The executive team led by Infiniti boss Peyman Kargar will reboot the company with a focus on profitability. "Premium brands should bring more money to the company, so that's the objective. We are not at the level we want to be," he told Automotive News. Several new products are on their way, including a crossover with a fastback-like roofline named QX55, and Kargar clarified many future models will ride on an architecture shared with parent company Nissan. It will be compatible with gasoline-powered, hybrid and electric drivetrains. He explained sharing platforms and components is necessary to save money because the company, like its peers and rivals, is spending a small fortune on developing electrified, autonomous, and connected technology. The shift will likely spell the end of the driver-friendly rear-wheel drive platform found under the Q50 and the Q60, but don't expect Infiniti to put its emblem on, say, a Sentra, and call it a day. It will remain a luxury brand. "The objective is to use these assets of the company, and then to reinject the money we are saving into the luxury experience and ingredients of Infiniti. We will put more money into Infiniti's future, but this money will come from the savings in globalized platforms," Kargar explained. The strategy he's outlining is one many of the firm's competitors have already adopted. Lexus, Acura, and Audi all build cars using parts sourced from their respective parent company. Lamborghini's Urus is related to the Volkswagen Touareg under the sheetmetal. Kargar noted every upcoming new model will be defined by an overhauled design language. We don't know if recent concept cars (like the QX Inspiration introduced in Detroit in 2019; pictured) will influence its upcoming vehicles. However, its future cars will offer nicer interiors, more user-friendly infotainment systems, and they'll receive tech features before Nissan's variants get them, which, oddly, hasn't always been the case in recent years. Infiniti's turn-around will start in 2020, when the aforementioned QX55 makes its debut after a brief delay.
