The new Chevrolet Malibu, due for an Australian launch next year as the Holden Malibu, will be offered in the US with a new 2.5 litre four-cylinder Ecotec petrol engine.
Earlier this year, GM confirmed that the new engine would deliver 140kW of power and 250Nm of torque - marking an increase of 25kW and 13Nm over the 2.5 litre petrol engine driving the outgoing Holden Epica.
This week, GM has finalised fuel consumption figures for the new direct-injected twin-cam engine. Paired with a six-speed automatic transmission, GM promises a highway figure of 7.8 l/100km. City and combined-cycle figures have not been released, however.
Among the new Ecotec engine's features is a redesigned combustion system, with a higher compression ratio and higher-flowing intake and exhaust ports in the cylinder head.
GM says it has reduced engine friction with the new Ecotec by an average of 16 percent across the operating range, thanks to a variable-displacement oil pump and an actively-controlled thermostat.
“The noise intensity is 40 percent less than our 2.4L direct-injected engine, which was named one of Ward’s 10 Best Engines,” Mike Anderson, global chief engineer, said.
“Engineers also tuned the 2.5L to deliver more of its torque at lower rpm, giving the Malibu a stronger feel at launch and during on-demand maneuvers, such as passing or accelerating on a freeway entrance ramp.”
Holden has confirmed that its Epica replacement will wear the Malibu badge when it launches in Australia sometime in 2012.
“Malibu will represent another major step forward in the Holden product offensive when it arrives late next year, filling a gap in our model line-up between our leading Cruze and Commodore models,” Holden Executive Director of Sales, Marketing and Aftersales, John Elsworth said.
Holden will release details specific to the Malibu model sold sold in Australia closer to its local launch in 2012.
