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.

Toyota, Honda, Mazda and Nissan recall 3.4 million vehicles for faulty airbags

Most vehicle recalls that take place these days are a result of some problem that happens during the manufacturing process by the automaker, but as we see here, parts suppliers can also factor in to problematic safety issues. Automotive News is reporting that a total of 3.4 million vehicles produced by Japanese automakers between 2000 and 2004 are being recalled globally due to faulty airbags produced by an outside supplier, Takata Corp.
According to the report, vehicles from Toyota, Honda, Nissan and Mazda are being recalled because of passenger front airbags that do not inflate properly. Globally, Toyota is said to be recalling around 1.73 million cars including 510,000 in the US composed of Toyota Corolla, Matrix, Sequoia and Tundra as well as the Lexus SC430 for the 2001 through 2003 model years; this is the second time this year the 2003 Corolla and Matrix have been recalled for an airbag problem. Honda is recalling 1.14 million models, Nissan another 480,000 and Mazda 45,463. The article says that Takata supplied faulty airbags to non-Japanese automakers, but it did not specify which ones.
Honda and Toyota have released information on their own websites about the recall, while Nissan and Mazda have not yet commented. Read official press releases from Honda and Toyota, below, and look for updates as we have word from the others.

Toyota outsells VW for global sales crown, apologizes with a vow to 'be honest'

Toyota Chairman Akio Toyoda bows in apology during a press conference Tuesday over the group companies' quality scandals. (Getty Images)   Every quarter, the stock market hangs on how much sales growth Tesla and other startups have experienced. There's growth, but then there's sheer output, and when it comes to deliveries dominance, one company can't be touched. Toyota on Tuesday announced that it remained the world's top-selling automaker for the fourth year running, with record sales of 11.2 million vehicles in 2023. Toyota's global group sales jumped 7.2% last year; the numbers include sales at Daihatsu and truck unit Hino Motors. Toyota's parent-only vehicles, which include the Toyota and Lexus brands, hit a record of 10.3 million vehicles in 2023. Gasoline-electric hybrids made up about a third of those. Battery electric vehicles accounted for less than 1%. Toyota's annual output handily beat runner-up Volkswagen Group, which this month reported a 12% rise in deliveries last year to 9.2 million cars. That growth was driven largely by demand for Audi, which sold 1.9 million vehicles. The auto industry in 2023 enjoyed a post-pandemic recovery as supply chain bottlenecks eased, though shipping problems through the Red Sea so far this year have stalled that progress by some automakers, causing some car plants in Europe to suspend production. Toyota's global group sales have now topped 10 million vehicles for nine of the past 10 years, except for 2020 when the COVID-19 pandemic delivered a blow to the auto sector. Scandals and an apology Toyota's chairman apologized on Tuesday for scandals at the three group companies. Daihatsu, Hino and affiliate Toyota Industries have been beset by governance issues involving certification test procedures for cars and engines that could potentially hurt the brand's global reputation for quality and safety. "I would like to express my deepest apologies to our customers and stakeholders for the inconvenience and concern caused by the successive irregularities at Hino Motors, Daihatsu and Toyota Industries," Toyota Chairman Akio Toyoda told reporters. He was speaking at an event to announce a vision for the Toyota group, which was founded by his great-grandfather and now includes 17 companies.
