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 GT86 14R-60 shows how to do lightweight at a steep price

Toyota is finally making good on its Griffon concept from last year with this limited-edition 14R-60 that basically hops through the Toyota Racing Development catalog to imagine the ultimate lightweight GT86 (the continental relative to the Scion FR-S/Subaru BR-Z). Unfortunately, it's not coming stateside, and even if this modded Toyobaru were coming here, you might not want to pay the rather steep price.
Like the concept, the 2.0-liter boxer engine still makes the same 197 horsepower and 151 pound-feet of torque. However, the drivetrain isn't entirely untouched thanks to a new air filter, engine oil cooler, a reinforced clutch, lightweight flywheel, and mechanical limited-slip differential from TRD. The six-speed transmission is also tweaked, with different gearing in first and second and an altered final drive ratio.
To keep things planted the suspension gets a new coilovers, a V-shaped tower brace in the front and another in the rear. Improved deceleration comes thanks to upgraded brakes. There also are even more goodies on the outside, including a complete body kit that includes a carbon-fiber roof and massive rear spoiler. The stock wheels are replaced with 18-inch forged magnesium units, as well.

New Toyota semiconductors could increase hybrid fuel efficiency by 10%

Toyota may have an ace up its sleeve in the fuel economy wars, as it's developed a new type of semiconductor that will allegedly help the company's hybrids net a ten-percent improvement in fuel economy.
The tech is still in development, although Toyota is already reporting five-percent gains during testing, six years before it plans to implement the new semiconductor in production vehicles, meaning the ten-percent improvement doesn't seem like an untenable goal. That is, until you hear from Kimimori Hamada, the project general manager of Toyota's electronics division.
"We are aiming for great improvement in fuel economy and miniaturization," Hamada told Automotive News. "This is a very challenging target."
