Geely and Renault joint venture will develop internal combustion and hybrid tech

China's Geely Automobile Holdings and French car maker Renault SA on Tuesday said they will invest up to 7 billion euros ($7.71 billion) in a new equally held joint venture to develop gasoline engines and hybrid technology for automobiles. The JV is aimed at manufacturing more efficient internal combustion engines and hybrid systems at a time when the focus of much of the automobile industry has been on the capital-intensive transition to purely electric vehicles. "We are pleased to be embarking on this journey to become a global leader in hybrid technologies, providing low-emission solutions for automakers around the world," said Eric Li, Geely Holding Group chairman. The new company will employ 19,000 people at 17 engine plants and five research and development hubs, Renault said. At launch, it is expected to supply to multiple industrial customers including Volvo, Proton, Nissan, Mitsubishi Motors, and PUNCH Torino. The JV aims to have an annual production capacity of up to five million internal combustion, hybrid and plug-in hybrid engines and transmissions, Renault added. Reuters reported in March that the new venture will see 15 billion euros ($16.53 billion) in annual revenue. Saudi Aramco, which signed a letter of intent with Renault and Geely in March, is evaluating a strategic investment in the new company, Renault said. The Saudi oil producer has been involved in advanced discussions to take a stake of up to 20% in the JV, sources said earlier this year. Big oil firms have worked with automakers to develop sustainable fuels and hydrogen engines in recent years. But a deal here would make Aramco the first major oil producer to invest in the car business. The joint venture is expected to be launched in the second half of 2023.

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.

Renault gives rhinoplastic upgrade to Versa for Indian market

What do you call a Nissan Versa with a new nose and a home in the Indian car market? A Renault Scala. Given a chrome grille insert, the blacked-out crossbar common to Renaults and a few other "status-enhancing" tweaks, the Scala is Renault's fifth offering in India and rounds out its segment coverage.
The Scala is not only positioned as a sedan with value pricing and luxurious equipment, it is presented as a carriage for the chauffeured classes: best-in-class roominess, leather seating, rear vents for the climate control and two cupholders in the rear armrest attend to the boss in the back.
An 86-horsepower diesel and a 99-hp gas engine take care of matters up front. Available now in three trims, it joins the Pulse hatch, Fluence sedan, and Koleos and Duster SUVs in Renault's Indian line-up, and comes with Renault's CompleteCare service and 24/7 Roadside Assistance.
