Lexus LX to get diesel engine?

Australian consumers appear poised to get another diesel-burning luxury SUV in the near future, and word is it's coming from Lexus, of all automakers. Sean Hanley, chief executive of the company's branch in Oz, recently told Aussie website Drive that he's "pretty confident" that the new engine for the LX is getting the green light.
Like in the US, the LX in Australia is currently only offered with a 5.7-liter, gasoline-burning V8. However, sales of the big SUV are presently minuscule Down Under, with Drive reporting just 153 LX570s sold in all of Oz last year. Hanley is negotiating with Japan to get the new diesel in hopes of boosting flagging sales. If his efforts are successful, it would be the first diesel engine offered in a Lexus there. Hanley didn't specify exactly which mill the SUV would get. However, given the LX's close relationship with Toyota Land Cruiser, the diesel 4.5-liter twin-turbo V8 already available in the Toyota in markets outside of North America seems like a natural choice.
Don't expect the variant to be hopping across the Pacific, though. Lexus spokesperson Allison Takahashi tells Autoblog she has heard "nothing" about an oil-burning LX coming to the US. That's not a huge surprise, though, because neither Toyota nor Lexus offer any diesels in their lineups today. Also, Lexus has only sold 1,981 LX570s through June, which only placed it ahead of the LFA supercar in the brand's sales. It's probably just not worth certifying the engine for such a low-volume model.

Toyota working on cars that hover above the roadway

Toyota is one of the largest automakers in the world, but it's not content simply building and selling conventional cars - it's been at the forefront of numerous advancements in ground transportation. It is widely credited with advancing the cause of hybrid propulsion, and alongside Audi and Google, is among the first automakers seriously testing self-driving cars. We could go on, but the news here is that Toyota is reportedly developing vehicles that hover above the road surface instead of rolling along it.
The news comes from Hiroyoshi Yoshiki, one of Toyota's tech gurus, who revealed at Bloomberg's Next Big Thing summer in San Francisco that the company is working on hovering cars - ones that travel just above the road surface, but don't actually fly in three-dimension space.
According to The Verge, a spin-off of our own sister-site Engadget, Yoshiki refused to elaborate on what the project entails and how far along it is. He was speaking along acting NHTSA chief David Friedman, who lauded such advancements as a "great taste of innovations to come," but stressed the significance of more concrete improvements to conventional automobiles - like inter-car communications to keep vehicles from colliding on the highway - as more relevant to today's industry.

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.
