Infiniti is blazing an unconventional path to electrification

When it comes to electrification, Infiniti has a history of speaking a great deal but doing little. The Nissan-owned company's plug-in offensive will start in the 2020s, and it provided preliminary details about the technology that motorists can expect to find in showrooms in the not-too-distant future. Eric Rigaux, Infiniti's general manager of product strategy and planning, told Roadshow the firm's engineering department is putting the final touches on two forward-thinking electrified powertrains. The first one will run solely on electricity, while the second one will rely on a gasoline-powered generator to provide more range. Both are being developed to fit into a flexible new platform. Technical details about the electric setup remain vague, so we don't know how big of a battery pack Infiniti will use, or how many motors will draw electricity from it. However, Roadshow learned the gasoline-electric layout will never need to be plugged in, because a 1.5-liter, three-cylinder engine equipped with Infiniti's innovative variable-compression technology will produce the electricity it needs to run. The triple won't directly spin the wheels; it will channel the juice it creates to a battery pack. It's not a zero-emissions solution, but it's one that makes a lot of sense, because users won't need to wait for a charge, and they'll be able to drive for about 500 miles between fill-ups. The now-defunct Chevrolet Volt featured a similar drivetrain, but owners had the possibility of plugging it in. Infiniti won't give motorists that option; there won't be a plug anywhere on the car. Fluid-filled motor mounts and active noise cancellation will ensure the passengers don't feel or hear the triple whirring away. Meanwhile, two electric motors (one over each axle) will deliver between 248 and 429 horsepower; final specifications haven't been signed off yet. And, because power will come from gasoline, there's no need to integrate a bulky battery pack into the chassis. Infiniti's future gasoline-electric models won't require anything bigger than a 5.1-kilowatt-hour unit, which can unintrusively be stuffed under the trunk floor or sandwiched between the floor and the rear seat. Infiniti chose a crossover to inaugurate its battery-electric powertrain; the QX Inspiration concept (pictured) unveiled during the 2019 Detroit Auto Show shed light on what the model will look like.

Infiniti Q50 steer-by-wire system took 10 years to develop [w/video]

Infiniti's Direct Adaptive Steering (DAS) is quite a novelty - the system employs no physical connection between the steering wheel and the front wheels under normal circumstances and instead relies on a computer, clutch and steering-angle actuator to guide vehicles down the road with input from the driver.
In our First Drive review of a 2014 Infiniti Q50 equipped with the system, we weren't overly impressed by the artificial feedback. But we can't help but be impressed with how long Infiniti spent on its development: a full 10 years, according to Autoline Daily in the video report below. A staggering 70 percent of the research and development time spent on DAS was devoted to getting the steering feel right, and unfortunately, our first impression suggests their results still leave something to be desired, as we found it lacked the sporty feeling a sport sedan should have.
The weight of DAS is comparable to that of a conventional steering system due to its complexity. For example, three ECUs are used in the first-generation DAS system to ensure there's never a loss of steering, but Infiniti is refining the technology and is working to simplify it to reduce weight. One day Infiniti hopes that only one ECU will be needed to control DAS. We just hope it doesn't take the Japanese automaker another ten years to get the steering feel right.

Race Recap: Singapore Grand Prix is about a safety car and submission

The Singapore Formula One Grand Prix is the Monaco GP of the Orient - a weekend known more for its glamour and time-slot than on-track action, with a temporary circuit that punishes every mistake, usually terminally.
Lewis Hamilton in the Mercedes-AMG Petronas got the best of Free Practice 1, opening the curtain on a possible resurgence of Silver Arrows performance. By the time qualifying was done, though, it was his teammate Nico Rosberg who lined up second on the grid, followed by Romain Grosjean with a beautiful performance in the Lotus, Mark Webber in the Infiniti Red Bull, and Hamilton all the way back in fifth. Behind them were Felipe Massa outqualifying Ferrari teammate Fernando Alonso, Jenson Button getting the McLaren into eighth, Daniel Ricciardo with another good Q3 effort to get into ninth, and the shocker of Esteban Gutiérrez getting his Sauber into the top ten for the first time this year.
At the front of the pack was Sebastian Vettel. Again. But he was only ahead of Rosberg by a single tenth of a second...
