Nissan CEO Makoto Uchida rules out closer capital ties with Renault

YOKOHAMA — Nissan is committed to its automaking alliance with Renault but will not look to deepen its capital ties with the French automaker any time soon, its new CEO said on Monday. On his first day in the new position, chief executive Makoto Uchida also pledged to repair profitability at Japan's No. 2 automaker and said setting realistic targets would be key toward that goal, as it tries to make a clean break from the leadership of former chairman Carlos Ghosn. "Closer capital ties with Renault are not a focus in the short term," he told reporters. Uchida became CEO of Nissan on Dec. 1, as the car maker tries to recover from a profit slump and draw a line under a year of turmoil after the Ghosn scandal. The ousted chairman is fighting financial misconduct charges in Japan. One of the new CEO's big tasks is to salvage ties with Renault, which have deteriorated since Ghosn's ouster as chairman of both companies. Renault holds a 43.4% stake in Nissan after it saved the Japanese automaker from financial ruin two decades ago, and has pushed for the two companies to merge. In rejecting a notion of a merger with Renault, Uchida, 53, echoes his predecessor Hiroto Saikawa, who stepped down in September. He added that the alliance must re-think how it can serve all of its three members, which also includes Mitsubishi Motors. "The alliance has to benefit each of its partners in terms of revenue and profit," he said. "We need to re-evaluate what has worked and what hasn't worked in the alliance in the past few years." The CEO called for Nissan to set "challenging but achievable" targets, adding that this and the launch of more new car models and vehicle technologies would be key to its financial recovery. Nissan is bracing for its lowest annual profit in 11 years and has slashed its dividend by 65%. Its struggles come at a time when car companies desperately need scale to keep up with sweeping technological changes like electric vehicles and ride-hailing. "Somewhere along the way we created a culture of setting targets which could not be achieved," Uchida said, adding that this had resulted in a focus on short-term results. "Years of this had led Nissan to its current "difficult situation," he said, using heavy vehicle discounting in the U.S. market as an example of how aggressive sales targets to grow market share had deteriorated the company's brand.

Nismo toying with crossovers and pickups

Nissan is apparently committed to turning its racing and tuning division into a bigger player, with new Nismo models coming out all the time. But while the Nismo division has until now focused primarily on hatchbacks and sports cars, the next project could be a truck. According to Aussie website CarAdvice in speaking to Nissan marketing chief Darren Cox and Nismo boss Shoichi Miyatani, the prospect of a Nismo-tuned SUV or pickup are definitely on the table. That could include a performance-oriented take on the Navara pickup, but also the Qashqai crossover – a prospect first mooted a year ago. And if the Qashqai and Navara are under consideration, there's no telling what Nismo might do with the likes of the Frontier, Rogue, Murano or even the Pathfinder. None of that is concrete at the moment, of course, but the market for performance crossovers seems only to be growing – and growing more accessible, too. The Germans keep making smaller crossovers and performance variants thereof, and even Fiat is said to be working on an Abarth version of the 500X. The Juke Nismo itself bridges the gap between hot hatches and performance crossovers, but apart from the 370Z Nismo and GT-R Nismo, most of the division's projects seem to be focusing on hatchbacks like the Pulsar and Versa Note.

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.
