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.

2014 Toyota Prius crash test rating drops to four stars

If nothing has changed, then how come something changed? That's the question behind the recent drop from five to four stars in the crash test rating for the Toyota Prius. As you can see on the National Highway Traffic Safety Administration (NHTSA) website, the 2014 Prius gets four stars overall while the 2013 got five. The two cars are basically identical, so what gives? Toyota says it is not sure why NHTSA rated the Prius a four this time. Starting with the 2011 model year, NHTSA updated its rating system and says in a FAQ that vehicles that had four- or five-star ratings could get lower ratings "even if no changes have been made to the vehicle." Green Car Reports says that the issue is a new set of frontal barrier tests that were conducted on the 2014 Prius last month and that resulted in the first new bits of crash test data for the car in years. The 2012 and 2013 Prius models were rated based on tests done in February 2011 on a 2011 Prius. All of these are variants of the third-generation model. The next-gen Prius is expected in 2015. Jana Hartline, environmental communication manager at Toyota Motor Sales, USA, told AutoblogGreen that the company doesn't quite know what's going on with the drop in crash test scores: There have been no changes in the test standards and no changes in the car, other than minor reinforcement for small overlap crash test which we believe did not compromise integrity. We are not sure why it rated a 4 this time. We are looking at the test results and we are confident the new generation will move back to 5 stars. 2014 Prius still has a five-star rating for the side crash test and four in the rollover test.

Toyota, Suzuki partner on hybrids, EVs, building cars for each other

NAGOYA, Japan — Toyota and Suzuki on Wednesday said they planned to produce electric vehicles and compact cars for each other to better compete with fast-changing technologies in the global auto industry. The agreement follows an initial R&D tie-up announced by Japan's No. 1 and No. 4 automakers in 2017, and will see more vehicles produced by Suzuki for Toyota, one of the world's biggest carmakers. Although Suzuki is far smaller, it is a dominant force in the fast-growing Indian market. The two automakers have been pooling their strengths. Toyota is a leader in hybrid technology and is investing heavily in automated driving, while Suzuki specializes in affordable compact cars — as many automakers struggle to keep pace with ballooning investment in EVs and self-driving cars. Under the latest agreement, Suzuki will source gasoline hybrid systems for cars it sells worldwide from Toyota, which pioneered hybrid vehicles with the Prius more than 20 years ago, the companies said in a joint statement. In return, Suzuki will produce two compact models for Toyota in India based on its Ciaz and Ertiga models. Further cooperation with Suzuki will help Toyota expand its presence in India, the world's fifth-largest passenger car market where it has struggled to grow sales due to lean demand for its lower-cost models. The deepening partnership between the two automakers will enable cost-conscious Suzuki to tap into Toyota's R&D firepower to develop lower-emission vehicles and self-driving cars — areas which Suzuki has admitted it is struggling to keep up. "We believe that the expansion of our business partnership with Suzuki ... will help give us the competitive edge we will need to survive this once-in-a-century period of profound transformation," Toyota President Akio Toyoda said in a statement. The two automakers will deepen their cooperation in India, where Suzuki's hybrid vehicles will be made using engines and batteries locally produced by Toyota. They will also join forces in Europe, where Toyota will produce electric vehicles based on its RAV4 SUV crossover and Corolla wagon for Suzuki, while Suzuki will supply Toyota with gasoline engines for compact vehicle models sold in the region. Suzuki will also produce its Baleno, Vitara Brezza, Ciaz, and Ertiga models for Toyota which will be rebranded and renamed as Toyota models for the African market.
