Consumer Reports says infotainment systems 'growing first-year reliability plague'

The Consumer Reports Annual Auto Reliability Survey (right) is out, and the top two spots look much the same as last year's list with Lexus and Toyota in first and second place, respectively. However, there are some major shakeups for 2014, with Acura plunging eight spots from third in 2013 to 11th this year, and Mazda replaces it on the lowest step of the podium. Honda and Audi round out the top five. This year's list includes six Japanese brands in the top 10, two Europeans, one America and one Korean.
Acura isn't the only one taking a tumble, though. Infiniti is the biggest loser this year by dropping 14 spots to 20th place. Other big losses come from Mercedes-Benz with an 11-place fall to 24th, and GMC, which declines 10 positions to 19th.
Perhaps unsurprisingly, it's not traditional mechanical bugs hauling down these automaker's reliability scores. Instead, pesky problems with infotainment systems are taking a series toll on the rankings. According to Consumer Reports, complaints about "in-car electronics" were the most grumbled about element in new cars. Problem areas included things like unresponsive touchscreens, issues pairing phones and multi-use controllers that refused to work right.

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 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.
