Infiniti G37 to be renamed Q40; new flagship sedan confirmed

Infiniti has already made it known that its aging G37 sedan will live on alongside the all-new Q50 through the 2015 model year, but little else for this sporty four door has been announced past the 2013 model year. As of this writing, there is no 2014 model shown on the company's consumer website. A new report from Car and Driver, however, indicates that like other models carried over to Infiniti's new naming convention, the four-door G37 will live out the rest of its days with a "Q" name after all.
Unlike the G coupe and convertible - renamed Q60 - the sedan will reportedly wear the Q40 designation until its ultimate demise. We reached out to Infiniti for more information, but a spokesperson only had this for us: "we have not provided any product details for post-2013 models. That will come at a later time." Previously, we had been told that the sedan would continue to live out its days under the G37 nameplate.
As for products that are actually new to the lineup, C/D says that the Q30 and the next-gen QX50 are both expected to arrive before the company launches a new range-topping flagship sedan as soon as 2016. Aside from a handful of reports suggesting this sedan exists (C/D says it's confirmed for production), there isn't much we know about it - including whether it will be called Q80, Q90 or something else entirely. It would appear there's plenty to look forward to from Infiniti's upcoming product lineup, and we are eagerly awaiting a 550-horsepower Q70 sedan and/or a production version of the Q50 Eau Rouge.

Infiniti Q60 Concept previews sexy styling, twin-turbo V6

Okay Infiniti, this was worth the waiting and teasing. Behold, the Q60 Concept, the coupe that foreshadows a future production two-door while also introducing a new family of 3.0-liter, twin-turbocharged V6 engines. It's fair to say we like it very much. Of course, this is not our first unfettered look at the Q60 Concept. Infiniti's final "teaser" image showed off the final product, but now we can analyze it from all angles, including the lovely, almost S-Class Coupe-like rear end and the clean, fashionable cabin. The Q60 Concept's design, particularly in the swoopy profile, comes across as organic and muscular, particularly in the shape of the front fenders and rear haunches. The car's dead front view reveals a few styling details that were overshadowed by the angle of the teaser image, like the interesting ridge that runs from the grille into the powerfully domed hood. A fixed glass roof gives the cabin an open-air feel, while the overall layout is largely reminiscent of the current Q50 sedan, only with cleaner, updated materials that we wouldn't bet on making production. Thin sport seats look supporting and feature quilted leather bolsters, while a two-tone steering wheel spices up the driving environment. Under the Q60 Concept's hood is the same 3.0-liter, twin-turbocharged V6 that was first shown on the Q80 Inspiration Concept from the 2014 Paris Motor Show. According to Infiniti, the direct-injected six-pot will arrive in a production car within the next two years. In the Q60, a seven-speed automatic handles power delivery, although it's unclear if a similar gearbox would be used alongside the production engine. Other notable features on this sleek two-door include Infiniti's Direct Adaptive Steering system and the new InTuition system, which promises a "fully customizable digital environment." Of course, we'll have much, much more on the Q60 Concept tomorrow, when it makes it arrives on the floor of the 2015 North American International Auto Show in Detroit.

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:
