Infiniti's variable compression engine in the 2019 QX50 is the first of its kind

The world's first variable compression ratio engine is here, in a production car. That car is the 2019 Infiniti QX50, debuting this week at the Los Angeles Auto Show. The midsize crossover has seen a refresh that has brought it an all-new platform together with new driver assist features, but it's the engine that's the centerpiece here. Nearly everything is continuously variable under the hood of the QX50 – not only the new shift-by-wire XTRONIC CVT. The new VC-Turbo gasoline engine is able to change its compression ratio from 8:1 to 14:1, or anything in between depending of the driving situation; whether there is need for top-end power or turbodiesel-like torque from low revs, or optimized fuel economy. The pistons' reach is continuously adjusted by an electric "Harmonic Drive" motor, which controls a multi-link system, affecting the top-dead-center of the pistons and changing the compression. The engine can also switch between efficiency-maximizing Atkinson cycle and regular combustion cycle, on the go – and there's both multipoint injection and gasoline direct injection employed. The result is 268 horsepower at 5,600 rpm and 280 pound-feet of torque at 4,400 rpm; good figures for a 2.0-liter four-cylinder gasoline engine with a single-scroll turbocharger. Infiniti says that the FWD version's fuel economy of 27 miles per gallon combined is 35-percent better than the previous-generation V6 engine; in AWD guise, it reaches 26 mpg, which is a 30-percent improvement. The new engine is pretty much all-aluminum, but the vaguely magical-sounding "transformative multi-link components" behind the variable compression system are made from high-carbon steel alloy. The engine's multi-link system also enables it to do away with any balancing shafts, and Infiniti compares its smoothness to a V6 rather than a regular four-cylinder. In addition to the aforementioned tech, the VC-Turbo engine has the world's first active engine mount vibration damping system to smoothen its operation even further. Related Video:

Infiniti previews its own Vision Gran Turismo

Every automaker and its parent company is lining up to design its own set of wheels for the GT6 as part of the Vision Gran Turismo program, and this latest one comes from Infiniti. Although nothing in the way of details were disclosed at this point, the two teaser images released today show that, like most of its compatriots, Infiniti's design is for a low-slung, track-focused, two-door sports car. Its long bonnet suggests a front-engined layout, with an intriguingly ovoid windshield framed by raised buttress A-pillars and Infiniti's signature dog-leg rear pillars. The aerodynamic profiling looks suitably advanced for a mythical beast like this one, with deep extractor vents cut into the hood, intersecting side sills running from the front brake vents, an enormous rear diffuser and an even bigger rear wing. More than that we couldn't tell you at this point, but we're sure video racers will enjoy driving this super-Datsun as much as the Nissan Concept 2020 Vision Gran Turismo released back in June.

Mystery shoppers love Infiniti, hate Tesla

Infiniti, followed by Lexus tied with Mercedes-Benz took the top two spots for best sales experience according to mystery shoppers from the latest Pied Piper Prospect Satisfaction Index, while EV manufacturer Tesla recorded the lowest overall score. Not surprisingly, premium brands dominated the top ranks. Including the three already mentioned, luxury brands occupied seven of the top ten spots and included Audi, BMW, Porsche, and the only American brand to crack the upper echelon, Cadillac. Toyota, Volkswagen, and Nissan rounded out the first ten positions. The news for domestic automakers isn't good. Aside from Caddy, the only other star-spangled automaker to score above the industry average is Chrysler. The rest of FCA, most of GM, and all of Ford fell below the line. But Pied Piper's mystery shoppers handed Tesla the biggest walloping – the company is ten full points below the next lowest brand, Volvo, and its score of 86 is 17 below the average of 103. It's baffling, considering the company's touted direct-sales model. "Tesla leaves me scratching my head," Fred O'Hagan, Pied Piper's president and CEO, told Wards Auto. "They own all of their stores, so you would think each one would be doing the same thing. But they're not. Tesla is consistent in its inconsistencies." O'Hagan added that there's a "huge variation" in Tesla's store-to-store effectiveness, and that in some cases, shoppers found showroom workers that acted more like "museum curators," Wards Auto reports. It might be popular to call Tesla the Apple of the car world, but based on Pied Piper's work, the brand has a long way to go to emulate the uniform shopping experience of an Apple Store. The news might be bad for Tesla, but even for the brands that scored below average, there's cause for celebration. Only Tesla and Mini lost points in this year's rankings, and only Mercedes and Lincoln held steady. Every other brand, including Infiniti, which topped the index for the first time, gained at least one point. The biggest improvements belong to Porsche, Land Rover, and Mitsubishi, which all jumped five points. Pied Piper's annual Prospect Satisfaction Index uses mystery shoppers – over 6,100 this year – from across the country to assess dealers and generate rankings from over 50 individual factors.
