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 asking NHTSA for fuel cell car safety exemption regarding electric shocks

Toyota is requesting an exemption from federal safety regulations that govern electric cars as it prepares to launch a small-scale hydrogen fuel-cell vehicle fleet.
The Japanese automaker is targeting Federal Motor Vehicle Safety Standard 305, which covers the packaging of high-voltage parts in electric cars. According to Uncle Sam, these systems need to be isolated so that passengers and first responders aren't electrocuted in the event of a crash. That seems pretty smart, but it's become a problem for Toyota's upcoming production fuel cell vehicle, as the mechanism that prevents electric shocks in low-speed crashes will apparently simply keep Toyota's car from even functioning.
Instead of the federally approved system, Bloomberg reports that Toyota plans to insulate the high-voltage wires and cables in the car, along with shielding electrical components like the fuel cells, electric motor and batteries with (presumably non-conductive) metal barriers.

Could high demand, low supply doom Toyota Mirai?

Toyota recently gave the world a behind-the-scenes look at the small-scale production of the Mirai hydrogen fuel cell sedan. A team of just 13 people assembles three of them per day, and the Japanese automaker is using this rigorous build process to prioritize quality for each one. Although, there's some concern about whether the Mirai could become a victim of its own, growing success. The company reportedly already has 2,000 orders for the Mirai just in Japan, and an anonymous Toyota executive tells Automotive News that the waiting list is now "two years or something" to receive one. Keep in mind, this figure is before customers elsewhere in the world have any requests in, and the US launch is planned for California this fall with sales in Europe starting this summer. The automaker is keeping North American demand somewhat in check by only planning to move 200 vehicles or fewer on the West Coast in 2015. So, unless Toyota can pick up the production pace, the waiting list seems likely only to grow longer. Automotive News speculates that the company might be in danger of Mirai customers losing interest if they are forced to build anticipation for too long. That especially could be the case with a new Prius likely to be unveiled by the end of the year that could lure folks away It seems that Toyota is trying to react to the higher-than-expected demand for its hydrogen-powered model, though. In December, the automaker invested $168 million to add two more assembly lines for the Mirai's fuel cell stack and hydrogen tank. Related Video:
