The 2014 Chevrolet Malibu arriving in dealerships this fall will be the first midsize sedan sold in the U.S. to offer fuel-saving stop/start technology standard on its 2.5L base model.

The Malibu has an EPA-estimated 25 city and 36 highway mpg – a 14 percent improvement in city fuel economy – at a starting price of $22,965, including an $825 destination charge but excluding tax, title, and license and dealer fees.

Stop/start technology helps customers conserve fuel by automatically shutting off the engine when the car comes to a stop, such as at stoplights. The engine automatically restarts when the driver takes his or her foot off the brake. During engine restarts, an auxiliary 12-volt battery powers electric accessories such as heating and air conditioning, power windows and radio.

Malibu’s stop/start system monitors – among other things – vehicle speed, climate control system operation and the force a driver applies to the brake pedal, to determine whether it is efficient to shut off the engine in certain driving conditions, such as stop-and-go driving.

In addition to stop/start technology, Chevrolet engineers incorporated valve-actuation technology known as Intake Valve Lift Control into Malibu’s 2.5L engine, which also contributes to improved fuel economy.

A new six-speed transmission makes its first appearance in the 2014 Malibu 2.5L. The 6T45 transmission includes improvements that reduce the energy required to pump transmission fluid, which enables additional fuel economy savings.

The new technologies on the 2.5L model enable the Malibu to deliver a higher combined fuel economy rating than the base engines of several midsize sedan competitors, including the Toyota Camry, Ford Fusion, Kia Optima, Hyundai Sonata and Chrysler 200.
