Fisker stock trades halted as talks with Nissan collapse

Fisker's talks with a large automaker for a potential deal have collapsed, it said on Monday amid growing uncertainty for the cash-strapped startup that last week paused electric-vehicle production.  Trading in the shares of the company, which did not name the automaker with which it was in talks, has been halted pending an announcement.  Fisker also said it will not be able to meet a closing condition related to its attempt to raise up to $150 million in funding by selling convertible notes after missing an interest payment.  Separately, Fisker said it would ask investors to vote on a proposal for a reverse stock split at a shareholder meeting on April 24, as it looks to maintain compliance with the Nasdaq's listing norms.  Reuters had reported earlier this month that Nissan was in advanced talks to invest in the company, however, earlier in the day, the Japanese automaker held an event in which it announced a long-term business plan, including its EV strategy, and said it was looking for partners in the United States.  Raising funds has been hard for loss-making electric vehicle startups, which have little in way of revenue as they struggle to ramp up production and deliver to customers, as the companies battle stiff competition and a tough economy.  The EV startup's shares have cratered this year, losing more than 90% of their value, after it flagged going concern risk in February and paused investments in future projects until it secured a partnership with an automaker.  Fisker pivoted to a dealer-partner model earlier this year, after it delivered less than half of the vehicles it made in 2023 due to logistics issues.    Earnings/Financials Fisker Nissan

Renault-Nissan goes for closer cooperation, outsells VW and Toyota

PARIS — Renault-Nissan plans to double cost savings to nearly $12 billion by 2022, partly through closer cooperation with Mitsubishi, but left key questions about the automakers' alliance unresolved. Chairman Carlos Ghosn has pledged to step up the pace of integration after Nissan took a controlling stake in Mitsubishi last year. The 18-year-old Renault-Nissan pairing has only recently begun rolling out cars on common architectures. Combined sales volumes are expected to rise to 14 million vehicles by 2022 from 10.5 million expected this year, with revenue advancing by a third to $240 billion, the alliance said at a news conference in Paris on Friday. However, any investors impatient for a new capital or management structure to speed integration and prepare Ghosn's succession were likely to be disappointed. There was "no answer from Ghosn on the possibility of a merger by 2022," Jeffries analyst Philippe Houchois noted.12 NEW ALL-ELECTRICS Ghosn has been seeking a new second-in-command, sources told Reuters in June. But such plans are linked to thornier questions about the balance of power between the two main carmakers and the French government's outsize clout as Renault's biggest shareholder, supported by double voting rights. Twelve new pure-electric models will be on the road by 2022 as Renault-Nissan seeks to defend the head-start it gained with the current generation of battery cars, spearheaded by the Nissan Leaf and Renault Zoe, as more competitors join the fray. With 5.27 million cars and vans delivered in the first half of the year, Renault-Nissan now claims the mantle of the world's biggest carmaker, ahead of Volkswagen and Toyota, even though Renault has never consolidated the sales of its 43.4 percent-owned Japanese affiliate into its own. Under existing plans, the alliance is seeking to increase synergies — from cutting costs and boosting revenue — to 5.5 billion euros next year from 5 billion recorded in 2016. SHARED PLATFORMS A fourth common vehicle platform will be shared across the alliance by 2022, the companies said on Friday, underpinning a future generation of electric cars which, together with hybrids, are expected to account for 30 percent of group sales. Renault-Nissan will aim to deliver more electric vehicles and also make greater use of shared technology and manufacturing processes.

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.
