New systems increase efficiency without compromising the driving experience
Cadillac has recently added dynamic driving performance to its list of attributes. Now as 2016 model year production begins, Cadillac adds new fuel-saving technologies. Active Fuel Management and Automatic Stop/Start technologies, and widespread use of a new 8-speed transmission, are combining to raise fuel economy ratings and reduce emissions in Cadillac’s portfolio.
Cadillac’s all-new six-cylinder engine contains Active Fuel Management, or cylinder deactivation, technology enabling it to seamlessly switch from six-cylinder to four-cylinder operation under certain light-load conditions, while maintaining excellent performance. The new 3.6-liter engine is part of the 2016 ATS, CTS and Escalade product lines. The luxury SUV’s V8 will shift to four-cylinder operation in many daily driving conditions, as will Cadillac’s all-new high performance CTS-V sedan.
Cadillac’s advanced engine technology will accelerate in the new Twin Turbo-powered CT6 prestige sedan, which will be the world’s only six-cylinder engine to combine turbocharging with cylinder deactivation and Stop/Start technology.
Cadillac’s ATS and CTS also offer a 2.0-liter turbocharged four-cylinder engine, the most popular choice among buyers. These models also see fuel economy improvements in 2016 via the use of Automatic Start/Stop, or AutoStop, technology. This system reduces emissions and fuel consumption by automatically turning off the engine when the car is stationary, such as at red light. The engine quickly and automatically resumes as soon as the driver releases the brake.
Previous Start/Stop systems often relied on the car’s battery system. Cadillac employs a voltage stabilization system powered by ultracapacitors to re-start the engine. This alternative power source inside the car enables smoother and quicker re-starts compared to previous systems, while enhancing durability by reducing strain on the existing electrical systems.
Cadillac’s new 8-speed transmission nets another efficiency gain, and like the new V6 engine, just started production in the 2016 ATS and CTS.
“While these new systems increase efficiency, a main focus in engineering at Cadillac is to integrate these systems smoothly with no compromise to the driving experience,” says David Leone, Cadillac executive chief engineer. “Our new 8-speed transmission was developed internally for fast and smooth shifting in every situation with Cylinder Deactivation and Start/Stop are integrated in a more seamless manner than our competitors.”
The result is cleaner and more fuel-efficient Cadillac models. CO2 output has been reduced up to 6 percent on 2016 ATS and CTS models.
