At long last, Infiniti plans a production EV

After years of false starts, it appears that Nissan's Infiniti division will finally launch a production electric car in 2019 and debut it as a concept in January at the North American International Auto Show in Detroit. Details at this point are scant, but Infiniti Executive Design Director Alfonsa Albaisa told Autocar the EV would be an all-new electric-only vehicle based on a new platform. Citing the company's grand prix-inspired Prototype 9 racecar concept that was shown a few weeks ago at Pebble Beach, Albaisa said consumers would see "parts of the car in a different context" on the concept EV. The Prototype 9's all-electric powertrain was developed by parent company Nissan's Advanced Powertrain Department. The last we saw of any electric offering from Infiniti was way back in 2012 with the LE Concept sedan, which was supposed to show up in dealerships two years later. Those plans were initially postponed in 2013 and then again in 2015 amid doubts over EV sales projections and larger concerns over boosting overall Infiniti sales. The LE had a 24 kWh lithium-ion battery pack paired with a 100 kilowatt electric motor delivering 134 horsepower and 240 pound-feet of torque.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.

Mystery shoppers love Infiniti, hate Tesla

Infiniti, followed by Lexus tied with Mercedes-Benz took the top two spots for best sales experience according to mystery shoppers from the latest Pied Piper Prospect Satisfaction Index, while EV manufacturer Tesla recorded the lowest overall score. Not surprisingly, premium brands dominated the top ranks. Including the three already mentioned, luxury brands occupied seven of the top ten spots and included Audi, BMW, Porsche, and the only American brand to crack the upper echelon, Cadillac. Toyota, Volkswagen, and Nissan rounded out the first ten positions. The news for domestic automakers isn't good. Aside from Caddy, the only other star-spangled automaker to score above the industry average is Chrysler. The rest of FCA, most of GM, and all of Ford fell below the line. But Pied Piper's mystery shoppers handed Tesla the biggest walloping – the company is ten full points below the next lowest brand, Volvo, and its score of 86 is 17 below the average of 103. It's baffling, considering the company's touted direct-sales model. "Tesla leaves me scratching my head," Fred O'Hagan, Pied Piper's president and CEO, told Wards Auto. "They own all of their stores, so you would think each one would be doing the same thing. But they're not. Tesla is consistent in its inconsistencies." O'Hagan added that there's a "huge variation" in Tesla's store-to-store effectiveness, and that in some cases, shoppers found showroom workers that acted more like "museum curators," Wards Auto reports. It might be popular to call Tesla the Apple of the car world, but based on Pied Piper's work, the brand has a long way to go to emulate the uniform shopping experience of an Apple Store. The news might be bad for Tesla, but even for the brands that scored below average, there's cause for celebration. Only Tesla and Mini lost points in this year's rankings, and only Mercedes and Lincoln held steady. Every other brand, including Infiniti, which topped the index for the first time, gained at least one point. The biggest improvements belong to Porsche, Land Rover, and Mitsubishi, which all jumped five points. Pied Piper's annual Prospect Satisfaction Index uses mystery shoppers – over 6,100 this year – from across the country to assess dealers and generate rankings from over 50 individual factors.
