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.

2017 Infiniti QX30 First Drive

If you've heard anything before about this car, the 2017 Infiniti QX30, it probably has to do with its corporate parents, an odd couple if there ever was one. Renault-Nissan, Infiniti's corporate overlords, inked a deal with Mercedes-Benz to share some mechanical components and platforms. That deal put a new, very modern 2.0-liter turbocharged inline-four under the hood of the Q50 and was the genesis of what you're looking at here. What are you looking at here? We drove this car in 2015, when it was called a Q30 – originally it was going to be the lower-riding counterpart to the slightly jacked-up QX30. Then Infiniti decided it'd make more sense to sell all variants of this vehicle as CUVs in the US, so we have three slightly different flavors of the QX30 instead. There's the normal version; the Sport, which is 0.6 inches lower; and the AWD, which is 1.2 inches higher. Infiniti brought us to Seattle to sample the Sport and AWD flavors on a semi-circumnavigation of the Puget Sound. It didn't rain a drop, thanks for asking, and instead was sunny and mild the whole time. It's easy to make the QX30 sound more confusing than it actually is. This is essentially a Mercedes-Benz GLA250 with full exterior styling and partial interior design by Infiniti, built in the UK alongside several other Nissans. The powertrain and chassis, including the optional AWD system, were all "co-developed" with partner Daimler, with final calibration and tuning by Infiniti engineers. Here's another way of explaining it: Infiniti needs an entry-level car to appeal to new premium car shoppers, and the QX30 is the prescription. It's a hatchback that's been given the mildest of CUV treatments and a lot of marketing descriptors. That's because hatchbacks are sales death in America. In Europe, they'll see right through the CUV posturing and realize it's just a hatchback offered in three different suspension heights. Whatever you call it to make it palatable to Americans, it's a useful little vehicle. This car is mechanically identical to the Q30, so there are some things we can gloss over. Both are powered by a transverse-mounted 2.0-liter Mercedes inline-four. It's a turbocharged, direct-injection gasoline engine, and it sure feels like one. It sounds like a rock tumbler full of nickels and runs out of breath at about 5,000 rpm. All versions make 208 hp at 5,500 rpm and 258 lb-ft of torque between 1,200 and 4,400 rpm – more than adequate but less than thrilling.

Weekly Recap: An '80s encore in the auto world

The '80s returned in a big way this week, as National Lampoon's, Ghostbusters, Miami Vice, and even Tetris were back in the news. While there were far more serious topics (see below), nostalgia mingled with modern marketing to put these Reagan-era favorites back in the spotlight. The '80s were alternately cold and corny at times, but their cultural touchstones can still generate big money. That's why Infiniti recreated an iconic scene from National Lampoon's Vacation (1983) for an advertisement that hawks the QX60 crossover. Actor Ethan Embry, who played Rusty Griswold in a later Lampoon's movie, pilots the Infiniti – which is serving as a modern Family Truckster – for a trip to Walley World. A blonde pulls alongside in a red Lamborghini. They flirt, and she drives on. Christie Brinkley, who played the original girl in the red sports car (she drove a Ferrari in the '83 flick), is riding shotgun and chides Embry with: "A blonde. In a convertible. Seriously?" Okay, it's hardly on the level of "here's looking at you," or even "you can't handle the truth," but it should resonate with '80s babies, many of whom are now having children of their own and moving into three-row SUVs like the QX60. Naturally, Hollywood is going back to the well, too, with a Vacation remake that premiers July 29. Meanwhile, Ghostbusters is returning next year, and director Paul Feig offered a peak at the new Eco-1 in this tweet. In the 1984 classic, the team drove a modified 1959 Cadillac. Now, it will drive a late '80s Cadillac. As expected, the announcement generated support and controversy from movie and car enthusiasts. His tweet had generated several thousand retweets and favorites in the days following the news. Though the '80s Caddy looks, uh, less elegant in comparison to the now-iconic fins and curves of the original Ecto-1, it's about the same time lapse into the past as the '59 Caddy was to viewers in 1984. Speaking of 1984, Miami Vice, which debuted that year on NBC, is seeing one of its hero cars hit the auction block, Mecum Auctions announced this week. The 1986 Ferrari used on the show will be offered for sale Aug. 15 during Monterey classic car week. The white supercar runs a 390-hp flat 12-cylinder engine paired with a five-speed manual transmission and was in storage after the show ended in 1989 until earlier this year. It has 16,124 miles on the odometer and is authenticated by Ferrari North America and Classiche.
