Infiniti Q50 Eau Rouge revealed ahead of Detroit

As fast as Infiniti is on the track with its sponsored Formula One racecar, the automaker sure is taking its time releasing details for the Q50 Eau Rouge Concept. This performance- and aero-tuned version of the Q50 sedan is heading for a big debut at the Detroit Auto Show, and Infiniti just released a new image and some more info on what we can only hope is a glimpse at future Infiniti Performance Line (IPL) products.
Influenced by the Red Bull Racing program, Infiniti's design team gave the Q50 a substantial once over with the concept getting an entirely new body compared to the production version of the luxury sedan making it both lower and wider. Previewed by an earlier teaser, the face of the Q50 Eau Rouge Concept has a mean look with massive intakes and a carbon fiber splitter. This new image also shows off additional cues like the lightweight, 21-inch wheels as well as the carbon fiber roof, side sills and door mirrors. While we only get this single image of the Q50 Eau Rouge Concept, Infiniti promises a carbon fiber rear splitter, dual exhaust and a "large integrated rear spoiler."
There is still no word on what handling or engine upgrades are in store, but hopefully those GT-R-inspired hood vents are only a hint at something monstrous lurking beneath the hood. Check out the full press release posted below for a few more details on the car, but we expect Infiniti to drop some more info on the Eau Rouge Concept before its official debut.

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 Q50S getting G37's hydraulic steering for 2016

Sometimes, new technology doesn't make things better. Take the march of power steering technology as an example. Electrically assisted systems are in vogue at the moment for their ability to increase fuel efficiency, but tuning them to offer good feedback remains something of a dark art. Some automakers get it, but most don't. The previous hydraulically assisted setups just seem to be inherently more communicative when driven with enthusiasm. And it looks like Infiniti might be learning this lesson the hard way.
In talking with Keith St. Clair, the luxury brand's head of product planning, Car and Driver has learned that the Q50S is probably going to ditch its standard electrically assisted steering in favor of a hydraulic system derived from the old G37, a model soon to be renamed the Q40. The system should make the sedan more engaging behind the wheel, but it still won't help those who tick the option box for Infiniti's controversial Direct Adaptive Steering drive-by-wire system.
According to St. Clair, Infiniti's engineers have heard the complaints of critics and previous G37 owners about the Q50S model's electric steering system, and wanted to see what they could do. They didn't have to go far to figure it out - all it required was taking the steering rack off of a G37 and putting it onto the Q50S. After a little tweaking, "the car is a blast to drive," St. Clair reports. Now, the company is said to be fast-tracking the switch, and it could be ready for the 2016 model year.
