Infiniti Emerg-E Concept

The Infiniti Emerg-E is a two-place hybrid gasoline-electric concept that made its world debut at the 2012 Geneva Motor Show. While its sleek shape and stunning styling dropped jaws, those on the green side of things immediately recognized it as a reskinned and updated Lotus 414E - itself a concept based on the Evora that debuted at the same show only two years earlier. Yet there is little wrong with a reworked, Infiniti-badged Lotus boasting 402 horsepower and 738 pound-feet of torque, especially when it features a lightweight, all-aluminum bonded chassis beneath an attractive carbon fiber skin penned by the automaker's Southern California design team.
The hybrid powertrain is all contained aft of the cockpit. Primary propulsion is accomplished with two electric motors, one on each rear wheel, both featuring its own single-speed transmission (this design eliminates the need for a differential and provides electronic torque vectoring control). Energy for the electric motors is stored in a 15-kWh lithium-ion battery placed behind the seats, which is chemically different from the lithium-polymer pack Lotus used in its 414E. Auxiliary propulsion comes from a Lotus-designed, all-aluminum, 1.2-liter three-cylinder gasoline engine, rated at 50 horsepower, that serves as a range-extender after the 30-mile life of the battery pack is extinguished. Teamed with an 8.1-gallon fuel tank, the combo allows the Emerg-E to cruise about 300 miles without stopping.
Offered the chance to take the Emerg-E for a quick loop around an autocross course in Southern California, I jumped at the opportunity.

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 Q50 Eau Rouge Concept could be something special

With one of Infiniti's chief goals being to adopt a less US-centric product lineup and burnish its standing on the global stage, Nissan's premium outpost will have to get serious about enhancing its offerings' performance and image credentials if it wants to take on the Germans model for model. It dabbled with the idea when it launched its Infiniti Performance Line (IPL), but its sole emissary to this point, the G37 IPL, offered little in the way of actual enhanced performance, focusing instead on visuals and a hefty price tag. This just-revealed Q50 Eau Rouge Concept suggests Infiniti is starting to get the message. Based on the cooking Q50, the Eau Rouge concept features both enhanced visuals courtesy of much more aggressive (and 20-millimeter-wider) carbon fiber bodywork inspired by the company's RB9 Formula One car and an improved stance thanks to a lowered, firmed suspension. As for what's lurking underhood this Detroit Auto Show star, that may be as much a theoretical at this point as anything else, but Infiniti president Johan de Nysschen offers a hint: "If we built this car I would expect it to feature over 500 horsepower and 600 pound-feet of torque," power arrived at via "a big personality, V-cylinder engine with forced induction." Johan, that sounds like a fine place to start. Infiniti Q50 Eau Rouge: Muscular, purposeful, refined - Q50 Eau Rouge concept provides a glimpse of Infiniti's design prowess for high-performance vehicles - Exterior features Infiniti Red Bull Racing Formula One design influences - Q50 Eau Rouge hints at future powerful product line Detroit / Hong Kong – The Infiniti Q50 Eau Rouge, revealed at the 2014 NAIAS Detroit Motor Show, is a concept car that expresses Infiniti's design vision of a high-performance Q50 premium sports sedan. The Q50 Eau Rouge embodies the arresting design features of the Q50 premium sports sedan – infused with the enticing spirit of Formula One. Featuring bespoke aerodynamic carbon fiber bodywork, Q50 Eau Rouge is lower and wider, possessing genuine road presence. This striking design is inspired by muscularity, aerodynamics, refinement, and understated power. "If we built this car I would expect it to feature over 500hp and 600lb/ft of torque. Through our various alliance partners we have access to a range of engines featuring this performance capability which, with a fair amount of engineering effort, can be developed to exhibit Infiniti character and accommodated within the Q50 engine bay.
