Renault and Nissan in talks that could reshape autos alliance

PARIS/TOKYO – Renault and Nissan said on Monday they were in talks about the future of their alliance, including the Japanese automaker considering investing in a new electric vehicle venture by its French partner. The talks, which could prompt the biggest reset in the alliance since the 2018 arrest of longtime executive Carlos Ghosn, have included consideration of Renault selling some of its Nissan stake, two people with knowledge of them said. Negotiations are expected to continue ahead of a Renault investor presentation in early November, when the French carmaker is expected to give an update on its new EV unit, which is code-named "Ampere." Renault owns about 43% of Nissan, which in turn has a 15% stake in its long-term partner. The French state also has a 15% holding in Renault. Shares in Renault rose by as much as 6% in early trading, making the stock the best performer on France's benchmark CAC-40 equity index. They were up 3.54% by 1105 GMT. Renault and Nissan said in a joint statement that they were "engaged in trustful discussions around several initiatives" including a potential Nissan investment in the EV venture and what they called "structural improvements" in their alliance. Renault CEO Luca De Meo, who was in Japan over the weekend, and Nissan CEO Makoto Uchida have been central to talks about reshaping its terms, a person familiar with the talks said. A group of Nissan executives, including Chief Operating Officer Ashwani Gupta, have also been involved in developing discussions in recent months, the person said. Renault is looking to win Nissan as an investor in its new EV venture, which it is setting up alongside a separate combustion engine unit, essentially splitting out the higher-growth and investment-hungry portion of its auto business. In exchange for investing in the EV venture, Nissan is looking to Renault to reduce its stake in the Japanese automaker, a person familiar with the talks said. The French dominance of the alliance has long been a point of contention for Nissan, which wants Renault to cut its stake to 15% to draw level with its own holding in Renault, the source familiar with the matter told Reuters. For Nissan, the talks could represent a chance to reset a structure that many executives at the Japanese firm have seen as unbalanced, given the way vehicle development work between the two carmakers has progressed in recent years.

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.
