GM’s engineers have created a powerful exhaust note by tuning each drive mode to provide a specific sound in the all-new 2014 Cadillac CTS. However, the engineers have a trick up their sleeves: they’re using the new CTS’s sound system to do it.
This isn’t the first time a manufacturer has used the sound system to enhance a vehicle’s engine note; BMW currently does it with its M5 sport sedan. Cadillac takes it a step further though, enhancing the car’s three driving modes–Tour, Sport, and Track–with a unique sound to give the driver a better impression of what is going on underneath the hood.
The team of engineers surveyed what sounds were pleasing to human ears. By listening to the sounds created by competing models, the engineers were able to create these tones in the new CTS. Microphones have been placed strategically throughout the cabin to listen to the engine and relay the enhanced tones through the Bose audio system.
“The sound enhancement system acts like a choir conductor, calling forth certain engine sounds to sing the loudest depending on the driving mode. 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,” said Dave Leone, CTS executive chief engineer, Performance Luxury Vehicles, in a statement.
As the centerpiece of the Cadillac brand for over a decade, the new 2014 Cadillac CTS continues to improve. Now in its third generation, the new CTS is now lower, longer, and lighter than its predecessors. Along with these innovations, the 2014 Cadillac CTS has a lower curb weight, more horsepower, and a higher structural stiffness than its main competitors. Pricing starts at $46,025 with destination, while the V-Sport model starts at $59,995 with destination.
