- Standard easy-access, steering wheel-mounted cruise control buttons
- Steering wheel radio controls on uplevel models
- Eight-way, heated power driver seat standard on LTZ and SS leather-appointed seats; six-way power driver seat standard on LS, LT with cloth seats
- New 7.0 Generation OnStar system offers Turn-by-Turn navigation

Three audio systems feature new, simple-to-operate radios that are compatible with the enhanced OnStar system. The base CD-radio includes a six-speaker system. An uplevel MP3/CD-radio is configured for XM Satellite Radio, with a two-line, 32-character reconfigurable display and the capability to select between AM, FM and XM stations without having to reset the frequency. An uplevel ICDX radio adds an in-dash six-CD changer. Impala also offers a premium Bose audio system. All radios include a standard auxiliary input jack for external devices such as an iPod or remote cassette player. Located in the lower right-hand corner of each radio, the input allows for plug-and-play through Impala's sound system.

XM Satellite Radio is standard on 2007 Impala SS, and available on LS, LT and LTZ.


2007 Chevrolet Impala Chassis and suspension

Quiet, smoothness and refinement are the ride and handling traits conveyed through the Impala's chassis and suspension systems. A robust front-end structure provides a firmer foundation to help reduce noise, vibration and harshness (NVH), while also enhancing steering and handling performance.

Impala's fully boxed upper frame rail assemblies have a wider, deeper and structurally stronger upper front tie bar, with slight machining differences between V-6 and V-8 models to provide room for the 5.3L small-block V-8 engine. Stronger ties between the upper and lower rails stiffen the front structure for improved ride and handling and a large, lower front-of-dash panel has been strengthened. It is constructed of Quiet Steel laminated steel, which consists of sound deadening material bonded between sheets of steel and reduces resonant sound.

An extruded aluminum engine cradle is used on both vehicles, too, and contributes to a smoother, vibration-free ride. The cradle's lateral stiffness (at the steering joint) is increased with a new, one-piece machined rear cross member and new aluminum rear body mounts, which helps improve handling control. Models equipped with a V-6 engine have a two-point engine-mounting system, while V-8 models have a three-point mounting system.

A power rack-and-pinion steering system is standard on all models, with entry-level LS model now sharing the same, responsive 13.3:1 steering ratio of LT, LTZ and SS models. All models also receive a quieter, improved-performance power steering pump and fluid reservoirs. The new system optimizes internal flow of the hydraulic steering fluid within both the pump and the reservoirs.

The front suspension features a MacPherson strut coil-over-spring independent setup with gas-charged struts and a stabilizer bar. Taller jounce bumpers in the front suspension help enhance stability and control. The rear suspension uses a trailing arm, tri-link setup with gas-charged struts and coil springs. A rear stabilizer bar is standard on all models. Based on the basic front and rear suspension designs, the Impala offers three levels of suspension tuning, each matched to the power and expected performance level of its respective model:

FE1 (16-inch wheels): Standard on models with the 3.5L V-6, the FE1 suspension provides improved control over previous base models without compromising ride quality.
