How Infiniti's 'gas-generated EV' isn't the jumbo shrimp of powertrains

LOS ANGELES — Infiniti recently introduced the concept of what it's calling "gas-generated EV" powertrain technology. At first read, and perhaps everyone thereafter, the term seems contradictory, not unlike "jumbo shrimp." How can an electric vehicle use gasoline? The answer to that is both a technological one and a marketing one. Technologically speaking, Infiniti's electrified powertrain concept is a series hybrid, most comparable to what Honda employs in its Insight, Accord Hybrid and new CR-V Hybrid. In the most basic of terms, the car's electric motor powers the wheels, the battery pack powers the electric motor, and the gasoline engine recharges the battery pack along with regenerative braking. By contrast, a parallel hybrid system as used by Toyota and others can power the wheels with the electric motor, the engine or, most frequently, both simultaneously. The result of a series hybrid is a powertrain that performs and feels more like an electric vehicle, while the engine generally whirs away, often not in step with what your right foot is doing. The Infiniti system is comparable to this, albeit with more powerful motors resulting in a more performance-oriented bent. Here's where things diverge, however. Under certain constant cruise conditions, say on the highway, the Honda system directly connects the engine with the drive wheels for greater efficiency. The Infiniti "gas-generated EV" concept will not, which frees engineers and designers to package the gasoline engine someplace other than under a front hood. In that way, it benefits from the sort of packaging advantages associated with electric vehicles. The closest comparable in this way is the BMW i3, which locates its tiny gasoline engine under the cargo area and does not attach it mechanically to the drive wheels. That's a range extender for an electric vehicle, though, which Infiniti is quick to insist is not what's going on here. There is no plug. This is a hybrid. So what's the deal with that name? If it walks like a duck and talks like a duck Â… Talking with Infiniti Group VP Jeff Pope, "gas-generated EV" is definitely a work in progress or at least a placeholder for something catchier and perhaps less contradictory in the future. "Why we're using 'gas-generated EV' is to get away from 'hybrid,' because 'hybrid' is associated with a parallel hybrid system, which has a gas engine and an electric motor that both run the powertrain.

New details emerge on Inifiniti QX50’s unique new variable-compression engine

Infiniti will release the world's first production variable-compression engine when it releases the 2019 QX50 midsize SUV sometime next year. Now we have some new details on the innovative new engine, which Infiniti is calling VC-T, for Variable Compression Turbo, after the luxury brand offered a prototype test drive. We wrote extensively about the complicated technology underpinning the new engine last year. It's the latest novel development that could represent a range-extender, if you will, for the embattled internal combustion engine in an era when automakers and governments are shifting their focus to electric vehicles. The VC-T is a new inline-four, 2.0-liter that combines the power of a high-performance turbo gasoline engine with the torque and efficiency of an advanced diesel engine, but without the latter's notorious emissions. It features the ability to seamlessly raise or lower the stroke of the pistons in the combustion chamber, depending on the driving conditions it detects and inputs from the driver, to select the best compression ratio—anywhere between 8:1, typical for high-performance engines, and 14:1 for high efficiency. In essence, it delivers the performance of a V6 but is much more efficient, with improved fuel efficiency of between 10 to 15 percent with its best competitors, per Car and Driver. You can view how it works in motion via the video below. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. It's also quieter, more lightweight and compact than V6 engines with comparable power outputs, estimated at 268 horsepower and 288 pound-feet of torque. In a prototype test drive, Car and Driver writes that the engine "felt very conventional" and responsive, with strong and smooth acceleration. "The only indication you have that the compression ratio is changing is from an indicator in the instrument cluster next to the boost gauge." The engine is expected to deliver fuel economy gains of 27 percent in combined city-highway EPA rating over the outgoing QX50, which had a 3.7-liter V6. The 2019 model, fitted with the VC-T, should get about 26 mpg in combined fuel economy, and it will get to 60 mph almost one second faster than its four-cylinder counterparts, Nissan's chief powertrain engineer, Shinichi Kiga, told Automotive News. The VC-T engine is the result of 20 years of development spanning more than 100 prototypes and around 300 patents at Nissan.

2017 Infiniti QX30 brings style in a small package to LA

There are already no shortage of luxurious compact crossovers on the market, like the Lexus NX and Mercedes-Benz GLA-Class. Infiniti clearly sees room for growth with the debut of the production QX30 at the Los Angeles Auto Show. The highly sculpted CUV arrives next year to offer another stylish entry in the segment. The production QX30 clearly adapts the swoopy concept's design from the Geneva Motor Show, but the designers soften things slightly. The kinked C-pillar comes straight from the earlier shape, and the arching character line now runs through both door handles along the side. Narrow lights at the front and rear also give the CUV a sporty look. Inside, leather and metallic trim abound, and the infotainment system sits high on the center stack. The QX30 will be available with diesel and gasoline engines, depending on the market, but the 2.0t on the fender here suggests this one uses the turbocharged unit from its Q30 hatchback sibling with 208 horsepower and 258 pound-feet of torque. A seven-speed dual clutch gearbox is standard on the CUV, and an all-wheel-drive system can send up to 50-percent of the power to the rear wheels as necessary. Infiniti hopes young buyers gravitate toward the model's bold shape when the QX30 goes on sale. LA seems like the perfect place to catch the eye of these potential customers. Infiniti QX30: A premium active crossover for all purposes • QX30 debuts as a new premium offering for global markets • Combines crossover appearance with signature Infiniti design cues • Delivers a confident drive and versatile attitude, aided by intelligent all-wheel drive • Intuitive technologies enhance safety, comfort and convenience • Part of first Infiniti production in Europe, at new facilities in Sunderland, UK • Simultaneous world premieres at Los Angeles and Guangzhou motor shows HONG KONG – The Infiniti QX30 premium active crossover is making its simultaneous global debut at the 2015 Los Angeles and Guangzhou international motor shows – signalling the next phase of the company's global growth strategy. Created for a new generation of premium buyers who appreciate category-defying design inside and out, the QX30 boasts a purposeful appearance that makes a bold visual statement as part of Infiniti's premium model line-up.
