A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

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 Q50 Eau Rouge running prototype driven by Sebastian Vettel

Infiniti's high-performance Q50 Eau Rouge concept might be one of the biggest teases in the current automotive world. It was first shown at the 2014 Detroit Auto Show as a body without an engine. Then, the sports sedan arrived at the Geneva Motor Show with a modified version of the turbocharged V6 from the GT-R under the hood, tuned to 560 horsepower and 443 pound-feet of torque, and with all-wheel drive. However, it was still just a concept. Finally, the Japanese luxury automaker is showing us what the Eau Rouge can do on the road - briefly.
The company brought reigning Formula One champ Sebastian Vettel along to get behind the wheel, for this all-too-short video from the Millbrook Proving Ground in the UK. There's more good news too. While Infiniti isn't saying that it's definitely going to build the Eau Rouge, it is "pressing ahead with the evaluation." More info about these tests will be released at the 2014 Beijing Auto Show at the end of April. Scroll down to watch Vettel drive the Q50 Eau Rouge and read a little more about it.
