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.

Lexus planning a hydrogen fuel-cell LS by 2017

Toyota's Fuel Cell System will certainly migrate to other vehicles in the carmaker's lineup, but Australian car site Motoring reports that one of the models at the head of the queue is the Lexus LS. According to its sources, the executive barge powered by hydrogen will be released by 2017 and take the top spot in the range, rolling in above the LS Hybrid. We're told that Toyota engineers will find a way to slide two hydrogen tanks into its bodywork with the same general setup as on the Mirai – one under the rear seats and another under the rear parcel shelf. The 150-kW fuel cell stack will be placed under the front seats. Motoring says the resulting sedan and its 220-kW electric motor would come in "at around 2,100 kg," which is 4,620 pounds; that's a ginormous 539 pounds less than the listed curb weight of the current LS Hybrid, and 387 pounds more than the standard LS. Assuming all goes as planned, it would have a range of roughly 238 miles, a few dozens less than the Mirai's range of about 300 miles. It would look slightly different, too, the front end getting larger intakes to cool the power unit. It wouldn't surprise us if Lexus does have a hydrogen LS planned – it would be a statement car, and the company likes making statements, even if few heed them; it has stuck with its LS 600h for the past seven years, yet of the 7,539 LS models sold through the end of November this year, only 61 of them were hybrids. The timing would be intriguing, however; by the time the LS hybrid came out, Lexus had already worked over its filet-and-potatoes models. And if the hydrogen version is going to come in above the $120,440 hybrid, well, that will be a statement indeed.

NHTSA may investigate new Toyota unintended acceleration case

After paying a $1.2-billion settlement to the US government last year, Toyota largely put the unintended acceleration recall behind it. Although, there were still some civil lawsuits to handle. A new case where the owner of a 2009 Lexus ES350 is petitioning the National Highway Traffic Safety Administration to open another analysis could draw the issue back to the forefront. Investigators are still deciding whether to research these claims further, though. According to this petition, the owner's wife was driving the ES350 in February 2015. While pulling into a parking space, the sedan allegedly surged forward, and there was a low-speed accident. The claim asserts there are at least two other similar cases in NHTSA's database: one in a 2009 Camry in 2009 and another in a 2010 Corolla in 2014. Specifically, this person wants an "investigation into low-speed surging in different models of Toyota automobiles in which the car starts accelerating and the engine RPM increases even when the accelerator pedal is not depressed," according to the agency. NHTSA will do further research into this person's claim and will decide whether to conduct a full investigation into the alleged issue. This won't be the first reappraisal of unintended acceleration in Toyotas by the agency in recent months, though. Between September 2014 and May 2015, NHTSA evaluated a similar petition with allegations covering 2006-2010 Corollas, and the government body decided to deny that one because the problem couldn't be replicated.

The petition was prompted by a February 2015 crash involving a model year (MY) 2009 Lexus ES350, which allegedly surged as the petitioner's wife was pulling into a parking spot.
