Toyota recalls 4,000 Tacoma pickups over valve springs

When you build as many cars and trucks as Toyota does, you're bound to run into the occasional recall. In the past month alone, the Japanese auto giant has recalled over 800,000 Camry, Avalon and Venza models over problems with the air-conditioning units, and 10,000 more before that over windshield wiper issues. Now Toyota has issued another recall notice, but this time for far fewer vehicles.
The recall revolves around the engine valve springs in the 2013 and 2014 Tacoma, specifically those fitted with the standard 2.7-liter four-cylinder engine and not the optional 4.0-liter V6. The issue is that the valve springs are prone to cracking and breaking over time, and results from improper maintenance of the manufacturing equipment used by one of the two suppliers that outfit Toyota with the components in question.
All told, some 4,000 vehicles will be subject to the voluntary recall, the owners of which will receive notice by mail. If you think that could be you and want to get a jump on the problem, you can read the announcement below and call Toyota yourself.

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.

Subaru Viziv 2 presages Tribeca replacement with diesel hybrid tech

Subaru is in the middle of a new product bonanza. It has recent replacements for the Impreza and Forester at dealers, and soon we're getting the WRX, Legacy and if rumors are right the new Outback as well. Now, there are rumblings that there could be two more models from the Japanese brand on the way with styling inspired by the Viziv 2 concept from the Geneva Motor Show.
According to a company insider speaking with Motor Trend, the crossover concept shows the way for the brand's future design language. The shape would be used on a smaller CUV that is still being kept quite secret, and a second, larger one that would replace the recently axed Tribeca. The bigger model is the first priority and is planned as a new technology showcase.
It's rumored to use a turbodiesel, four-cylinder boxer engine that would be boosted with one electric motor on the front axle and two at the rear, with a plug-in hybrid system sourced from Toyota. It should provide a great mix of torque and fuel economy. A smaller flat-six engine would be a second powertrain option. Though the Viziv 2 concept only seats four, the production version would probably offer three rows.
