Renault has announced an all-new diesel engine which promises 25 percent improvement in fuel consumption over a similar engine. The Renault Energy dCi 160 is the first engine from the French carmaker to benefit from twin-turbocharging.
This 1,598 cc diesel engine produces 160 hp and 380 Nm of torque, which, according to Renault, is in the league of 2-liter engines in terms of performance. Thanks to the twin-turbos, fuel consumption and CO2 emissions face reductions of 25 percent, says Renault.
Speaking about the turbochargers, Renault says that the first turbo is a "very low inertia" turbo providing high low-end torque for pull-away and mid-range acceleration. About 90 percent of the 380 Nm of torque is available from 1,500 rpm thanks to this turbo.
The second turbocharger works at higher engine speeds and produces as much as 100 hp per liter of displacement. Thanks to these twin-turbos, the engine is always at its optimum efficiency, which in turn results in better fuel efficiency and emissions, says Renault.
Renault says that this engine will find application in its D- and E-segment models. In India, this engine could be an ideal fit for the Koleos SUV, which otherwise uses a 2.0-liter diesel engine. Renault may also extend this engine to Mercedes-Benz, which could use it to power the base models of the new C and E Class.
