Toyota says president, chairman of scandal-hit Daihatsu unit to step down

TOKYO — Toyota Motor Corp said on Tuesday both the president and chairman of Daihatsu Motor will step down almost a year after the small-car unit said it had rigged collision safety-tests. The departures are among the most drastic changes Daihatsu has made so far, as Toyota seeks to return the brand to its roots as one of Japan's most iconic compact car makers. Toyota faces a potential hit to its reputation from the safety certification lapses at Daihatsu, as well as separate governance issues at truck maker Hino Motors and affiliate Toyota Industries. The scandals at the three companies triggered a rare apology of Toyota Chairman Akio Toyoda last month. In a statement, the world's top-selling automaker said its chief executive officer for the Latin America and Caribbean region, Masahiro Inoue, will replace Soichiro Okudaira as Daihatsu's president effective March 1. Daihatsu's chairman, Sunao Matsubayashi, will also step down and will not be replaced, Toyota added. The outgoing Okudaira had worked at Toyota for nearly four decades before becoming president of Daihatsu in 2017, a year after it became a wholly owned Toyota subsidiary. Toyota Chief Executive Koji Sato told reporters, however, that the organizational change at Daihatsu was not carried out as a punishment for the outgoing executives. In volume terms, Daihatsu accounted for 7% of Toyota's total group sales of 11.2 million vehicles in 2023, including those of the luxury Lexus brand and Hino Motors. Given the misconduct over the safety test certification applications, Daihatsu also will be removed from a commercial vehicle partnership known as the Commercial Japan Partnership Technologies (CJPT), the automaker said in a separate statement. The partnership was established in April 2021 by Toyota, Hino and Isuzu Motors to facilitate technology development for commercial vehicles. Suzuki Motor and Daihatsu joined in July the same year. Daihatsu's 10% equity stake in the partnership will be transferred to Toyota, the statement said.

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.

Thanks to smaller engines, vehicle dependability falls for first time in 16 years

As automakers have made engines smaller and smaller to improve fuel economy, problems in those vehicles have gotten bigger and bigger. That's the synopsis of a J.D. Power vehicle-dependability study, which found that dependability dropped for the first time in 16 years, largely because the proliferation of four-cylinder engines is causing the vehicles to be less reliable. Specifically, the number of problems per 100 vehicles (or what J.D. Power calls PP100) during the past 12 months for 2011 model-year vehicles rose six percent from the year-earlier figures for 2010 model-year cars. Singling out four-cylinder vehicles revealed about a 10-percent increase in problems during the past year. This issues largely related to engine hesitation, rough transmission shifting and lack of power, signaling the inability of vehicle makers to iron out some of the problems in their smaller engines as they strove for better fuel economy. Six- and five-cylinder engines proved far more reliable. Among car brands, BMW's Mini sub-brand came out as least reliable, with 185 problems per 100 vehicles during the past year. Toyota's Lexus badge was easily the most reliable, with just 68 problems per 100 vehicles. Coming in second place was Mercedes-Benz. The overall average was 133. Check out J.D.

Power Reports: Increased Engine and Transmission Problems Contribute to Decline in Vehicle Dependability for The First Time in More Than 15 Years General Motors Company Receives Eight Segment Awards, While Toyota Motor Corporation Garners Seven and Honda Motor Company Earns Six WESTLAKE VILLAGE, Calif.: o Owners of 3-year-old vehicles (2011 model year) report more problems than did owners of 3-year-old vehicles last year, according to the J.D. Power 2014 U.S. Vehicle Dependability StudySM (VDS) released today. The study, now in its 25th year, examines problems experienced during the past 12 months by original owners of 2011 model-year vehicles. Overall dependability is determined by the number of problems experienced per 100 vehicles (PP100), with a lower score reflecting higher quality. The study finds that overall vehicle dependability averages 133 PP100, a 6 percent increase in problems from 126 PP100 in 2013. This marks the first time since the 1998 study that the average number of problems has increased. "Until this year, we have seen a continual improvement in vehicle dependability," said David Sargent, vice president of global automotive at J.D.
