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 spruces up Q70L Bespoke Edition for Shanghai [w/video]

"Luxury" is a relative term. Take the Infiniti Q70, for instance, which most of us would find plenty luxurious. But some buyers – in China especially – wanted more, so Infiniti stretched it out into the Q70L. And now it's revealed the even more luxurious Q70L Bespoke Edition. Revealed for the first time at the Shanghai Motor Show down the coast from the company's global headquarters in Hong Kong, the Infiniti Q70L Bespoke Edition is designed to "fill the gap between the current interiors in production cars and luscious interiors of Infiniti's concept cars." That's been materialized through a quilted white leather cabin space with four individual seats hewn "by meticulous craftsmanship and three-dimensional textures." It all looks pretty swank to us, but not the kind of space you'd want to put your kids in with their juice boxes, crayons and dirty soccer uniforms.

2022 Infiniti QX60 Review | Redesigned and relevant for the first time

Previously an afterthought in its segment, the completely redesigned 2022 Infiniti QX60 is a large luxury SUV now worth considering. It's far more stylish on the outside, and it's combined with a more luxurious interior with great standard technology and convenience features. It drives much better thanks to a new transmission and sharper suspension tuning. It all adds up to a real competitor. That doesn't mean it's a class-leader, but it's well matched to similarly priced options from Acura, Lincoln, Cadillac, Volvo, Jeep and Hyundai. In fact, with a base price of just over $47,000, it's cheaper than many of the luxury-branded alternatives, and very competitive with the high-end options of mainstream brands. Its one real weakness is a lack of powertrain options. Many vehicles in this segment have at least a couple engines to choose from, including hybrid options. Infiniti offers only a single V6 option. But the affordable price point, spacious and well-appointed interior, and good driving dynamics nevertheless make it a luxury SUV you should check out.

The Infiniti QX60 is completely redesigned for 2022. You can read more about the changes in our first drive review. What are the QX60 interior and in-car technology like? Some of the biggest improvements to the QX60 are inside. The dash has a low and wide lower plane that feels modern and airy. The air vents are hidden in one wide opening in this zone, and various surfaces feature stitched upholstery. Base models feature gloss black trim, with upper trims getting aluminum or natural finish wood trim. The top Autograph trim, which is pictured in this review, combines that lovely wood trim with unique-looking quilted leather on top of the dash. All QX60s feature a 12.3-inch touchscreen infotainment system. It runs basically the same infotainment suite that you find on Nissans, and that's a good thing. It features large, easy-to-find and easy-to-press icons. It all runs quickly and smoothly and is responsive to taps. We also appreciate that climate and audio controls have dedicated controls below the air vents. The volume and climate knobs are particularly appreciated, though the touch-sensitive buttons are less so.
