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.

Recharge Wrap-up: Renault-Nissan hits 250,000 EVs, will the next Toyota Prius be an SUV?

Will the next Toyota Prius be an SUV? Mazda and Toyota recently reached an agreement to share powertrain technologies, which will help Mazda comply with California's tightening ZEV restrictions with a plug-in vehicle. On the flip side, Toyota will have access Mazda's Skyactiv diesel powertrain, which a source tells Motoring will be used in an SUV based on the Toyota Prius (and, as Hybrid Cars suggests, on the Toyota C-HR concept). Interestingly, the collaboration will also give Mazda access to Toyota's fuel cell technology, which could mean more hydrogen powered cars on the road and the subsequent expansion of hydrogen fueling infrastructure. Could it also make way for a long-awaited hydrogen powered rotary-engine sports car from Mazda? Read more at Motoring. Samsung SDI unveiled two new lithium-ion stationary batteries at Intersolar Europe. In doing so, Samsung throws its hat in the ring with the likes of automakers Tesla and Mercedes-Benz, using knowledge from electric vehicle batteries in the arena of home solar energy storage. In addition to its 3.6-kWh battery, its new 5.5-kWh and 8.0-kWh batteries offer storage solutions at a larger, more practical scale for solar customers. Called the All-in-One, the battery system, borrowed from electric vehicles, is made up of a photovoltaic inverter, battery PCS and lithium-ion battery, and promises efficiency, compactness, fast installation and an affordable price.

The quarter-millionth EV was a white Renault Zoe sold to a French computer engineer from Bordeaux named Yves Nivelle. While he credits a government program offering a ˆ10,000 rebate for EV buyers trading in an older diesel vehicle for helping him make the decision to pull the trigger on the new Zoe, "I have to say, I was convinced the first time I drove the car. It's a real pleasure to drive and it feels good to do my part for the environment," says Nivelle. The Alliance had sold around 31,600 EVs from January to May this year, up 15 percent from the first five months of 2014. See the video above, and read more in the press release below. Renault-Nissan Alliance sells its 250,000th electric vehicle • Historic EV milestone reached in early June • Alliance sells half of all EVs globally • EV sales up nearly 15 percent through May vs.

New Toyota Supra may get a twin-turbo Lexus V6

We've heard endless rumors that a successor to the much loved and much missed Toyota Supra is in the works. Toyota hasn't done much to deny these conversations. On the contrary, the FT-1 concept from two years ago and the partnership with BMW have only fueled the fire. Now, talk of a new Lexus engine has led to speculation about the supposed Supra's powertrain. To be clear, this is mostly heresay. Few things have actually been confirmed, but based on what we know a few conclusions can be drawn. We know that BMW and Toyota are working on a joint product. We've seen mules testing out in the wild. In BMW guise, the possibly Austrian-built car will more than likely powered by turbocharged inline four and six-cylinder engines. Unless Toyota wants to use Bimmer power, they'll need to shoehorn one of their own under the hood. That leads us to this rumor of a twin-turbocharged V6 that will presumably power the new Lexus GS and LS. Japanese automotive publication Mag-X first reported on this engine. It was then picked up by YouWheel and Car Keys. Mag-X cites Toyota insiders and even gives an engine code, 943F. This engine allegedly will make more than 400 horsepower and more than 300 lb-ft of torque. While unconfirmed, this makes sense for Lexus. Nearly every luxury competitor has a six-cylinder engine with forced induction. While Toyota has previously had turbocharged inline-sixes, they've never produced a factory turbo V6. Every automaker is downsizing engines in an effort to meet fuel economy and emissions regulations. Toyota and Lexus will follow suit. Taking that V6 and tuning it for a performance application is a solid, if unverified, possibility. Related Video:
