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 drops detail about 414-hp Hybrid-R concept powertrain

The Toyota Yaris Hybrid-R Concept has been teased already, offering up little glimpses and details of the Frankfurt-bound vehicle. And while those few, shadowy shots have been great, we've really wanted to know how this hatchback would deliver its promised 400-plus horsepower. Under hood sits a 1.6-liter, race-derived, direct-injection, turbocharged four-cylinder that powers the front wheels. Sounds peachy, but with 414 horsepower splashed across the page, we're going to need something more than a 1.6-liter, turbo four.
A supercapacitor, developed from the Toyota TS030 Hybrid Le Mans racer sits in place of a hybrid's traditional battery packs. The benefit, according to Toyota, is that power can be more rapidly absorbed and discharged than in a traditional battery system, like nickel metal-hydride.
The gas engine is joined by a trio of 60-horsepower electric motors. Two of the them power the rear wheels, while the third sits between the engine and the six-speed, sequential gearbox. Developing the same amount of power as the rear-axle motors, this centrally located motor channels power to the race-derived supercapacitor during braking, and ships extra grunt to the rear wheels under acceleration when the front wheels start to lose grip. Besides the distributive power of the central motor, the rear electric motors can adjust the amount of torque flowing to each wheel, much like a differential.

Unintended acceleration settlement hits Toyota's Q4 bottom line

Depending on how you want to look at things, the US Attorney's Office $1.2-billion dollar settlement with Toyota in March over its unintended acceleration recall was either a big blow to the company or completely inconsequential. From January to March, net income fell five percent to 297 billion yen ($2.89 billion), compared to 313.9 billion yen ($3.05 billion) a year ago. However, the automaker still posted record full-year profits worldwide.
Operating profit also fell in the US by 9 percent to $498.1 million for the quarter, but sales were up by 6 percent to 581,261 vehicles. According to Automotive News, global revenue was still up from January to March by about 13 percent and vehicle sales were up 6 percent to 2.58 million units.
However, the payment to the feds did little to hold the company back last year. For the fiscal year ending March 31, 2014, Toyota had net income of 1.82 trillion yen ($17.7 billion), compared to 962.1 billion yen ($9.5 billion) in the last fiscal year. Total vehicle sales were also up.
