2025 Infiniti QX80 First Drive Review: So close to being great

NAPA, Calif. – Confession time. I kind of forgot that the Infiniti QX80 exists. Sure, itÂ’s gotten a refresh or two in the past few years, but it's essentially been the same big olÂ’ three-row SUV since 2010. IÂ’m pretty sure I used to call it Fudgie the Whale. Or maybe it was Pudgie the Whale. Like I said, itÂ’s been a minute. Now IÂ’ve gotten a taste of the 2025 QX80 and hey, what do you know, there is a lot to like. The third-generation of the body-on-frame SUV goes big on tech, style and comfort, making it a respectable triple into the right-center gap. However, its ride quality keeps the QX80 from being a home run. FudgieÂ’s V8 was nixed in favor of a 3.5-liter twin-turbo V6 good for 450 horsepower and 516 pound-feet of torque. Sure, it doesnÂ’t sound quite as good as the older powerplant, but it produces more power and better fuel economy to boot – 18 mpg combined with rear-wheel drive and 17 with four-wheel drive. The old one managed only 15 mpg with four-wheel drive. With low-mpg numbers like these, thatÂ’s actually a huge difference. The new turbo V6 is well-mated to a nine-speed automatic transmission, putting the power down to the rear wheels as standard in Pure and Luxe trims, or all four wheels as an option with those trims or as standard with the higher Sensory and Autograph. There are no complaints about power delivery. It has more than enough grunt for merging and the transmission downshifts readily for easy passing. There are five drive modes as well as a Personal setting, but I spend my time alternating between Standard and Sport. The latter tightens up the steering and powertrain, allowing the SUV to hustle fairly well on a twisty road without much body roll. ItÂ’s no Mercedes-AMG GLS, but starting at under $85,000 including destination, itÂ’s not nearly as expensive either. ItÂ’s when youÂ’re just toddling around town that the ride quality becomes a problem. All but the base Pure trim comes equipped with an “Electronic Air Suspension” and “Dynamic Digital Suspension,” the latter function monitoring the QX80Â’s motions to electronically apply damping forces. This isnÂ’t necessarily anything new in the automotive world, but other manufacturers just do it better. Up and down motions are well-controlled, but IÂ’ve been in row boats with more side-to-side stability. My head gets tossed around like IÂ’m piloting a Jeep on a dusty back road, and all IÂ’m doing is driving the paved streets of Napa Valley, California.

Infiniti QX30 Concept is ready to join the compact crossover fray

Today, the compact crossover market is an automotive Klondike. Automakers are scrambling to stake their claim on an increasingly segmented, increasingly valuable landscape. That's especially true in the premium market, where every Audi Q3, BMW X1, Mercedes-Benz GLA, Lexus NX and Buick Encore sold takes up a piece of market share that requires a great deal of effort for another automaker, in this case Infiniti, to reclaim. That makes the new QX30 Concept, debuting this week at the 2015 Geneva Motor Show, an extremely important vehicle for the Nissan-owned brand. The QX30 Concept has already been "earmarked for production" and will be launched next year, according to Infiniti. When that happens, we'll see a compact CUV with toned down styling from the vehicle shown here, much like the upcoming Q30 production model. It's fair to say the looks of the QX30 are in direct opposition to those of the aforementioned Lexus NX. Where that car is sharp and angular, Infiniti's designers emphasized the "spontaneous and fluid" look of the new concept. Infiniti's most recent, Q50-inspired design language works nicely in a compact CUV form factor. The double-arch grille and its flanking headlights give the QX30 a refined, almost predatory look. That, as it turns out, is intentional. "The Q30 Concept was like a panther, lithe and slender. We transformed the QX30 Concept into a mountain lion, strong and muscular," Infiniti's Executive Design Director Alfonso Albaisa said in a statement. The strong, wavy character lines in the profile lead into the short, chopped rear overhangs. Above the beltline, the rear window is raked forward aggressively, lending the QX30 a coupe-like profile. In the cabin, we can already see the makings of a production car's interior, with two strong material choices – dark brown and blue leather – highlighting the dash. On the concept, purple accent lighting is emitted from the center stack's controls, while the violet shade carries over into what looks like a digital instrument cluster and the speaker surrounds in the doors. Sections of quilted leather on the seats, meanwhile, look very nice, but we doubt they will make it to production on what is ultimately going to be a reasonably priced vehicle.

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.
