Enhanced Ride Comfort and a Quieter Cabin

The original Mazda CX-7 was one of its segment's most sophisticated vehicles, and this aspect is carried forth with the facelift. Its body shell's torsional rigidity is increased by 5 percent, which improves ride comfort and softens the road noise.

The engine line-up now includes a new-generation 2.2-litre turbo diesel that is one of the quietest and most refined in the non-premium SUV segment. Its aluminium lower block, for instance, is mounted to the cylinder block at 18 separate points for extreme rigidity and low engine noise. A front chain drive cassette-type balancer shaft helps reduce engine noise and vibrations, and a special rear-wheel torque control of the diesel version suppresses resonance in the rear drivetrain.

The bonnet and engine compartment noise insulators have been improved to efficiently suppress highfrequency noise. New insulators are installed on the suspension towers and the wheel housings. New urethane foam used in the A-pillars, and a thicker dash insulator and floor mat are used for the first time.

Mazda CX-7 facelift's high-performance DISI petrol version also has NVH (noise, vibration and harshness) updates, including new suspension tower insulators and new engine compartment and dash insulators that are denser and better at keeping noise levels in the cabin low.

Wind noise is lower than ever before, too. NVH engineers counteracted the noise that side winds make when striking the A-pillars by using a large moulding that prevents air separation. This can cause a major pressure difference at this part of the car, which increases noise. The new moulding keeps the air from separating and results in a significant reduction of wind noise into the cabin.
