A $30 million federal- government grant, half funded by the Department of Energy is development of a high efficiency Cummins four-cylinder diesel engine to be used in the Nissan Titan.
This engine will allow the Titan to shed its guzzler status and become one of the most fuel-efficient full size pickup trucks on the market. This 2.8-liter direct-injection turbocharged four-cylinder will likely boast over 30 mpg on the highway and promises to deliver as much torque as small-displacement gasoline V-8s. The Cummins ISF engine is offered in 2.8 and 3.8-liter displacements is capable of 168-hp and 443 lb-ft of torque. This engine is being developed for use in the next generation 2015 Nissan Titan.
