By remapping the delivery of power in the shape of a peaking wave rather than in a short-lived burst, Infiniti redesigned the way you experience acceleration. It is called Acceleration Swell: a progressive, seemingly limitless rush that builds faster the faster you push the 328-hp 3.7-liter VVEL® V6.
Engineers took 1,000 acoustic measurements to understand how sound would behave in the Q40 so that the speaker choices and locations would reproduce music with the richness of a live performance. Then they used a $30,000 home audiophile system as a benchmark to build the available Infiniti Studio on Wheels® by Bose®. With the unique Driver's Audio Stage setting, the sound is optimized to focus on the driver, creating a closer connection between artist and audience.
To help enhance rear-wheel grip when accelerating, the Traction Control System senses wheelspin and automatically reduces engine output and/or brakes the spinning wheel to help give you a surer foothold. Acting in tandem with the Traction Control System, Vehicle Dynamic Control[*](VDC) compares actual vehicle cornering performance to the driver's input, adjusting power levels and applying appropriate brake pressure to individual wheels to help correct oversteer or understeer, helping keep the vehicle on the steered path.
The switches and controls in your central console have been carefully engineered for instinctive reach and use. With a consistent level of resistance, and crafted for instant recognition, each button is designed with the philosophy that every little detail matters.
