Cadillac applies art and science to CTS engine sounds

Cadillac engineers applied the principles of psychoacoustics, the science of sound perception, and car-guy instinct to create powerful and pleasant exhaust notes for the all-new 2014 CTS midsize luxury sedan.

Knowing that engine sound communicates throttle response to the driver, CTS engineers uniquely tuned each selectable driving mode – Tour and Sport– to provide the driver with a specific sound impression of what’s happening under the hood.

Tour mode purrs with refinement and the Sport mode growls with power.

The team drew upon its knowledge of what tones sound the most pleasing to human ears based on the study of psychoacoustics, surveyed the sounds made by competitor models and relied on their own ears when selecting final tones. The integrated electronic sound enhancement system gathers and measures information from the engine and uses Bose digital signal processing to deliver desirable tones through the Bose audio system inside the normally quiet passenger cabin.

“The sound enhancement system acts like a choir conductor, calling forth certain engine sounds to sing the loudest depending on the driving mode,” said Dave Leone, CTS executive chief engineer, Performance Luxury Vehicles. “We used our ears to tell us what sounded the best and programmed the system to listen for those tones. It is Cadillac’s Art and Science design philosophy applied to engine sound,” he added.

The CTS has been the centerpiece of Cadillac’s portfolio for more than a decade. The third-generation CTS is one inch lower, 127 mm longer and more than 91 kg lighter than its predecessor. The new car also has lower curb weight, higher structural stiffness and more horsepower than its primary competitors.

Engineered from the ground up to deliver a driving experience that combines sport-tuned handling with world-class comfort, the all-new CTS includes segment-exclusive Magnetic Ride Control and electronic limited slip differential, which constantly monitors rear-wheel rotation from one side versus the other to ensure optimal handling on a variety of road conditions.
Pricing for the 2014 CTS standard model in the UAE starts at Dhs185,000 . Two Collections of option packages – Luxury and Performance– will be offered with either the 2.0T turbocharged four cylinder or 3.6L naturally aspirated V6 engine in either rear- or all-wheel drive.
