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 EV coming in 2021

Infiniti announced that it will offer new electrified vehicles starting in 2021. Nissan CEO Hiroto Saikawa said that its luxury brand will build its first all-electric car in 2021, as well as new "e-Power" vehicles – series hybrids with batteries charged by gasoline generators. Nissan has introduced e-Power vehicles in other markets, including the Note e-Power and the Serena e-Power minivan. Now it will extend that technology to Infiniti, providing a similar driving experience to an EV with the convenience of a gas-powered vehicle. Infiniti also said that we can expect "beautiful vehicles" like the Q Inspiration Concept that debuted at the 2018 Detroit Auto Show. Infiniti doesn't plan on producing the Q Inspiration, but it will certainly influence future vehicles in terms of both styling and technology. The Q Inspiration uses variable compression technology, which the company intends to use to improve efficiency and performance of its gasoline-powered cars. Infiniti expects half of its global sales to be electric vehicles by 2025 (it's not clear whether the automaker is lumping series hybrids into the electric vehicle category). And while there's no way that Infiniti will release a production version of its all-electric Prototype 9 EV, seen above, we'll hold onto that dream anyway.

2023 Infiniti QX80 gets higher base price and Amazon Alexa compatibility

Infiniti has released pricing information for the 2023 QX80, its biggest and most expensive SUV. The body-on-frame family hauler costs more than during the previous model year, but it gains a handful of additional tech features and the Infiniti Premium Care maintenance plan. Offered in three trim levels, the 2023 QX80 carries a base price of $74,395 including a $1,695 destination charge. That figure corresponds to the rear-wheel-drive Luxe model, but "entry-level" is a relative term: it comes standard with 20-inch wheels, a 13-speaker Bose sound system, leather upholstery and wood interior trim. For context, the 2022 QX80 Luxe cost $71,995 including a $1,395 destination charge. Pricing for the full range is as follows: QX80 Luxe rear-wheel-drive: $74,395 ($2,400 more than in 2022) QX80 Luxe four-wheel-drive: $77,495 ($2,400 more than in 2022) QX80 Premium Select rear-wheel-drive: $78,995 ($2,215 more than in 2022) QX80 Premium Select four-wheel-drive: $82,095 ($2,215 more than in 2022) QX80 Sensory rear-wheel-drive: $86,045 ($2,415 more than in 2022) QX80 Sensory four-wheel-drive: $89,145 ($2,415 more than in 2022) While prices are up across the board, which is par for the course, Infiniti expanded the QX80's list of standard features with Amazon Alexa compatibility and a haptic feedback function in the steering wheel for the lane departure warning system. And, like every member of the 2023 range, the QX80 comes with the Infiniti Premium Care plan that includes up to three years of inspections, oil changes, and tire rotations. Built in Japan, the 2023 Infiniti QX80 will reach dealers across the nation in the coming weeks. Related video: This content is hosted by a third party.
