Nissan, Mitsubishi confirm plans to invest in Renault EV unit Ampere

PARIS — Renault's longstanding alliance partners Nissan and Mitsubishi confirmed plans to invest in the French car maker's electric vehicle unit Ampere and use it to develop EVs for the European market, the companies said on Wednesday. After years of contentious partnership, the announcement on Wednesday confirms that the new alliance between the three automakers is smaller and more pragmatic, focusing on regional cooperation. Nissan and Mitsubishi confirmed they would invest respectively up to 600 million euros ($647.46 million) and 200 million euros in Ampere, which has been carved out from the rest of Renault and is due for a public listing next year. Nissan will become "a strategic investor" in Ampere, Makoto Uchida, CEO of the Japanese car marker told reporters, adding the company may use the EV unit's software and connectivity innovations in other markets outside Europe. "Developing electric vehicles all over the world alone would be very challenging," he said. Ampere will develop and manufacture an electric version of the compact Nissan Micra for the European market and a medium-sized electric SUV for Mitsubishi. Renault CEO Luca de Meo said Ampere will cut the costs for the Micra for Nissan by 50%. The alliance partners also confirmed their joint projects in Latin America and India. In September, Renault, Nissan and Mitsubishi ended their common purchasing agreement, which they said would allow them to focus on individual projects and adapt more quickly to regional differences in automotive markets. At the end of July, Renault and Nissan finalised the terms of a restructured alliance after months of negotiations. Talks dragged on for months longer than expected due in part to Nissan, which was concerned about protecting its intellectual property in future collaborations.

Daimler and Nissan venture to build cars in Mexico

Nissan and Daimler have been partnering ever closer for years, and now an unnamed source has told Reuters that the automakers have agreed to a 50-50 joint venture in Mexico that would build Infiniti and Mercedes-Benz models. Given that the rumors about just such a deal go back nearly six months and similar rumblings are years old, this arrangement has been a long time coming.
The insider tells Reuters that a memorandum of understanding was signed between them last month to build the Mercedes GLA-Class and new Infinitis at Nissan's Aguascalientes factory. The rumor didn't say when production would begin. It wouldn't be the first time the two automakers have decided to share this platform - Infiniti will build its Q30 compact on it in the UK next year.
The partnership between the Renault-Nissan Alliance and Daimler goes back to 2010 when the companies signed an agreement to share engines, factories and platforms. Since then, products of the partnership have included the underpinnings for the next-generation Smart and Renault Twingo and shared engines among some other models.

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.
