Stop-start technology will be offered as standard on the 2015 Chevrolet Impala’s base 2.5-liter engine, General Motors has disclosed. The technology improves the new Impala’s fuel economy by 5 percent. According to GM spokesman Chad Lyons, the implementation of stop-start technology in the Impala is part of the carmaker’s bid to widen the use of the system in its vehicles.
He said that the stop-start technology will become “more prevalent” in GM vehicles. The stop-start technology improves fuel economy by turning off the engine in certain conditions like stop-and-go traffic.
The revamped Impala has become a flagship vehicle for Chevrolet and is the second GM vehicle to offer the stop-start technology as standard. The 2014 Chevrolet Malibu was the first GM unit to offer the system as standard, improving its fuel economy by around 14 percent.
The 3.6-liter engine Impala will not be offered with the stop-start system as standard due to its weight. Lyons remarked that the technology is not so effective in a heavier engine.
According to a Navigant Research report, sales of vehicles laden with stop-start technology will surge to 55.4 million units in 2022 from 8.8 million in 2013. GM will start rolling out the 2015 Impala this summer.
“Stop/start system customer research indicates they want the engine to start up as quickly and smoothly as possible after a stop,” said Mark Meyers, Chevrolet Global Vehicle Performance manager.
The 2.5-liter Impala will have a starting price of $27,735 while the 3.6-liter Impala will have a base tag of $30,960. Both prices include shipping.
