Toyota mulling Cummins diesel for Tundra?

When Bloomberg spoke to Toyota USA Sales CEO Kazua Ohara recently, we highlighted his comments on the possible return of the Toyota Supra. However, the interview started with Ohara discussing the Tundra, and how it would take time to pinpoint and hone the pickup truck's brand image in the minds of consumers. That effort could get a boost, with a report in Edmunds saying that Toyota is "evaluating" the addition of a Cummins turbodiesel to the Tundra's engine options.
The Cummins powerplant is one of two options for the moment, the other being a hybrid powertrain. If the oil-burner got the thumbs-up, Toyota would follow the recent example of Nissan, which announced it would put a Cummins turbodiesel into its 2015 Titan. While the two Japanese companies make a closer comparison since they're both talking about Cummins applications in light-duty trucks, if it happens, it could be seen as further diluting the once-exclusive tie-up that Ram trucks has had with Cummins even though Ram has used Cummins in its heavy-duty truck.
Toyota hasn't said when it will decide on which direction to take, but either will be a move for the better in the view of segment watchers; PickupTrucks.com said the first of its top-five fixes for the Tundra would be a better engine, perhaps a diesel-electric hybrid from Toyota's Hino unit. Cummins told Edmunds it can supply a second manufacturer with the 5.0-liter diesel that Nissan will be using, so we wouldn't be surprised to see it end up in a Toyota or somewhere else.

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.

Recharge Wrap-up: Audi to build Q6 e-tron in Brussels, Boris Johnson test drives Toyota Mirai

Audi will build the Q6 e-tron at its factory in Brussels, Belgium. Production for the electric vehicle - which will be based on the concept car from the Frankfurt Motor Show in September - is slated for 2018. Its expected driving range of about 311 miles should help make it competitive against the Tesla Model X. Audi's Brussels plant is also where the A1 is made. It employs about 2,500 workers and produced about 115,000 vehicles in 2014. Read more from Automotive News Europe. During a visit to Toyota Headquarters, London Mayor Boris Johnson confirmed that Transport for London will be the UK's first Toyota Mirai customer. Mayor Johnson traveled to Japan on a three-day trade mission, and took a test drive of the fuel cell vehicle. "By embracing this technology of the future, we aim to consolidate hydrogen's role as a practical alternative fuel for the 21st century and beyond," says Johnson. "I am sure that Transport for London will provide the ideal environment for us to see everything Mirai can do and, in doing so, take another great step towards improving air quality in our city and protecting the health of Londoners."

The South Coast Air Quality Management District (SCAQMD) has delivered 12 electric commercial lawn mowers to government and nonprofit organizations in San Bernardino County. The donation of the electric mowers is part of a demonstration program to promote zero-emissions equipment. At prices ranging from $3,000 to $20,000, the electric mowers cost about 25 percent more than their gas-powered counterparts, but their lower operating costs can make up for the price difference in about two years. In addition, they produce about half the noise, and save about 600 pounds of harmful emissions per year. SCAQMD plans to deliver five more of the mowers as part of the same program.
