Toyota unveils two new small displacement engines

Toyota introduced a pair of brand-new engines in Japan today, that it says will eventually spawn 14 different variants by 2015. Where these two engines stand out in today's world, is that neither mill boasts direct injection, and both are naturally aspirated.
The larger of the two is a 1.3-liter, while the smaller engine, a 1.0-liter, was developed in collaboration with Daihatsu. What makes these two unique is that they both use the Atkinson cycle. Now, we aren't going to bore you by explaining just what this is - there's Google for that. Suffice it to say, Atkinson engines are highly efficient, but that efficiency comes by sacrificing power. That's why they're so popular in hybrids, which can offset the power losses.
This focus on fuel efficiency extends throughout the new engines, which also benefit from tweaks like a cooled exhaust gas recirculation system and a trick intake port, while the 1.3 employs Toyota's iE variant of variable valve timing. Both engines can be fitted with stop-start tech. According to Toyota, when fitted with stop-start the 1.3 should provide around a 15-percent bump while the 1.0-liter will increase economy around 30 percent, when they arrive on the road.

Details about next-gen Toyota Prius emerge

The Toyota Prius is undeniably the king of the hybrid market in the United States, with a 39.4 percent market share in 2013. With the next-generation Prius likely to go on sale in 2015, Toyota is trying to build an even more efficient hybrid to keep its control of the market.
Keeping cost down will be one of the major concerns of the new Prius. The next generation will ride on the new, modular Toyota New Global Architecture platform. The lighter underpinnings will improve efficiency and will reduce production costs by allowing for more shared components among vehicles. Toyota will not reveal how many vehicles will use the new platform. But even with the cheaper platform, price will remain a concern. Toyota is still deciding whether all versions of the next Prius will use lithium-ion batteries or whether some models will stick with the heavier nickel-metal hydride batteries to keep cost down.
Of course, the reason most people buy the Prius is because of its great fuel efficiency. Toyota will aim for at least an 8 percent improvement in fuel economy in the next Prius, which would increase it to 58 miles per gallon city and 52 mpg highway.

Toyota recalling 342k Tacomas due to faulty seatbelt pretensioners

Toyota is voluntarily recalling 342,000 Tacoma Access Cab pickups, produced between 2004 and 2011. The wide-ranging recall is due to faults in the screws that attach the belt pre-tensioner to the belt retractor. There are concerns that the screws can loosen themselves over time, especially if the access door is opened and closed with too much force. It's important to note that the recall only covers the driver and front passenger seat, and is limited to just the Access Cab trucks. Other body styles aren't affected.
If the screws come loose, the pre-tensioner and retractor spring could separate from the belt entirely, which would be bad news in a crash. There's no mention of injuries or accidents due to the faulty pre-tensioners. Owners affected by the recall will be notified soon, and asked to come in for recall service.
