Toyota Tundra could get Cummins diesel option

Toyota is weighing whether to offer the Tundra with an optional Cummins diesel motor.

Toyota has been roundly criticized for its conservative redesign of the Tundra full-size pickup, but now the automaker is mulling the addition of a new engine that could go a long way towards returning the truck to relevance.

Speaking with Edmunds, Rick LoFaso, corporate manager for light trucks at Toyota Motor Sales, revealed that Toyota is weighing whether to follow Nissan's lead and offer a Cummins diesel in the Tundra. Nissan recently announced plans to source a 5.0-liter turbodiesel V8 with roughly 550 lb-ft of torque from Cummins for the next-generation Titan.

"I think Cummins would bring instant name recognition and obviously they are a leader in diesel engine technology," LoFaso said. "The diesel engine is something that is on our evaluation list."

LoFaso stated that Toyota is also considering hybrid technology for the Tundra. Toyota began jointly developing gas-electric truck technology with Ford in 2011, and, while that partnership has since fizzled, the Japanese automaker is continuing to work on its own version of the system, which would be a natural fit for the Tundra.

Toyota hasn't indicated when it might reach a decision about adding diesel and hybrid powertrains to the Tundra's options list.
