BMW, Toyota outline new tech joint venture, new sports car

Back in June, Toyota and BMW announced a "memorandum of understanding" outlining plans for the two companies to join forces on future products and technology development. On Thursday, they signed a more formal and binding agreement that goes further into detail about the partnership, and it all sounds pretty exciting. The two announced they will work together in four main areas:
Joint development of a fuel cell system
"Set up a feasibility study to define a joint platform concept for a mid-size sports vehicle"

Lexus eschews production in China over quality concerns

One of the more popular trends in the auto industry is setting up production operations in China. Mainstream manufacturers like Ford, General Motors and Volkswagen have done it, and even luxury marques like Audi, BMW and Mercedes-Benz have or will soon have manufacturing ops in the People's Republic.
One company that isn't building cars in China, though, is Lexus. The Toyota-owned luxury brand still manufactures all of its vehicles in Japan (aside from a few RXs, which are built at a Toyota factory in Canada). According to Tokuo Fukuichi, Lexus just isn't ready to build cars there yet.
"The German Three have a brand image that they have cultivated over the past century in their long history, but Lexus is not in people's minds like that yet," Fukuichi-san told Reuters UK.

Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.
