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:

2014 Infiniti Q50 priced from $36,450*

With the 2014 Infiniti Q50 going on sale this summer, Infiniti has finally released pricing for its all-new and newly named sedan. In base form, the Q50 will start at $36,450 (*including $905 for destination and handling), which represents a drop of $900 compared to the current G37 Sedan.
In standard form, the Q50 is available in base, Premium and Sport trim levels with each offering the option of all-wheel drive for an additional $1,800. All gas-only Q50s come with the automaker's excellent 3.7-liter V6 engine, but stepping over to the Q50 Hybrid gets you a smaller 3.5-liter V6 paired with an electric motor. The Q50 Hybrid, which is available in Premium and Sport trim levels only, will begin at $43,700 for a rear-wheel-drive Sport model.
Potential buyers who preorder and ultimately purchase a Q50 during the unspecified "program period" will also get a free iPad mini. Scroll down for the official press release breaking down all trim levels and price points.

Infiniti parts ways with Red Bull Racing

The partnership between Infiniti and Red Bull Racing is done. The team announced that it will no longer run under branding from the luxury automaker and will drop the Infiniti name from its own. The shift is effective at the end of this year. Infiniti signed on as a sponsor of the Formula One team back in 2011 when Red Bull was at the height of its dominance and on the path to the second of four consecutive world championships. Two seasons later it stepped up to naming rights, with the team officially rebranded as Infiniti Red Bull Racing. But while the cars ran under motivation from the automaker's ally Renault, they stopped short of rebranding the engines as Infiniti's, leaving it in the unusual situation of being a title sponsor of (but not directly involved in) an F1 racing team. For next season, Red Bull will continue running the Renault power unit, albeit rebranded under the TAG Heuer name. In the process, the team will no longer have any branding from the French automaker or any of its associated brands. Meanwhile sister-team Toro Rosso is switching from Renault to Ferrari power for next season, while Lotus is prone to switch back to Renault engines and ownership. The French automaker also recently canceled its support of the feeder series known until now as Formula Renault 3.5. Infiniti has carried out only limited racing programs in its quarter-century history. Aside from the Red Bull partnership, it directly sponsored Sebastian Vettel up until his departure for Ferrari. The company also supplied IndyCar engines in the late 1990s, then sponsored the Indy Lights series for a few years. It recently helped a privateer team prepare a Q50 for the British Touring Car Championship, but otherwise hasn't had any top-tier factory racing programs to speak of. That makes it one of the few Renault Nissan Alliance brands (and Japanese automakers) not to actively participate in motorsports. Related Video:
