The 2007
Silverado and Sierra are available with five suspension systems, each
tuned to provide an optimized ride with smoothness, a greater feeling
of isolation from the road and minimal body movement; all suspensions
feature monotube front shocks. The suspensions include:
Z83 –
solid, smooth ride
Z85 –
enhanced handling and trailer towing
Z71 –
enhanced off road capability
Z60 –
maximum street performance (offered with 20-inch wheels)
NHT –
maximum capacity trailering package
In a first
for the segment, GM’s sophisticated StabiliTrak electronic stability
control system is standard on crew cab models and available on extended
cab models. Partnered with the new brake system and four-channel electronic
brake controls, the system provides more precise, controlled ABS stops,
as well as enhanced traction/yaw stability.
360-degree
perimeter of safety protection
Silverado and Sierra are built on new, stronger fully boxed frames that
are designed to provide increased crush protection during a crash. High-strength
steel reinforcements are strategically located on the frame to enhance
crashworthiness. They also feature new compatibility brackets that ensure
better interaction with lower-riding vehicles during a crash.
Driver control
is bolstered through enhanced dynamics, such as wider front and rear tracks,
as well as more responsive suspensions – including a new coil-over-shock
front suspension design and rack-and-pinion steering – that deliver
smoother, linear and more precise characteristics for a more confident,
sure-footed driving performance.
Additional
safety features include:
New,
roof-mounted head curtain side air bags inflate to restrain outboard
passengers in both seating rows, offering protection during side-impact
and rollover events; they are sized specifically to all three cab styles
and each has its own dedicated inflator for optimized fill rates into
each curtain. The air bags are integrated into the chassis and body
structures for enhanced passenger protection.
Dual-stage
frontal air bags with GM’s passenger sensing system are standard
on all models.
Segment-first
front safety belt pretensioners with both front and rear crash sensors.
StabiliTrak
electronic stability control system is standard on crew cab models and
available on extended cab models – and is a first for the segment.
Partnered with the new brake system and four-channel, four-sensor electronic
brake controls, the system provides more precise, controlled ABS stops,
as well as enhanced traction/yaw stability.
A high
capacity brake system with a new, four-channel ABS system provides superior
stopping capability. ABS is standard on all models and is linked to
the StabiliTrak electronic stability control system to help mitigate
the occurrence of rollover events.
Four-wheel
drive models feature the Autotrac active transfer case, which helps
keep the vehicle sure-footed in slippery driving conditions. When shifted
to the “Auto” mode, Autotrac engages all-wheel drive traction
automatically.
An exclusive
Eaton automatic locking rear axle also helps provide additional traction
when needed, particularly when towing.
A new
Ultrasonic Rear Parking Assist system is available and provides visual
(LED lights) and audible warnings of objects behind the vehicle.
A revised
and easier-to-use tire pressure monitoring system is standard on all
models. It alerts the driver via a signal on the instrument panel driver
information center if a tire’s inflation status requires attention.
A segment-exclusive
factory-installed remote vehicle starting system is available on most
models – a first for GM’s full-size trucks – providing
customers with the convenience of starting the vehicle during inclement
weather or other situations.
Power-adjustable
pedals complement increased front seat fore/aft travel to enable smaller-stature
drivers to find an optimized driving position.
All retail
models come standard with the OnStar Generation 7 system, including a
one-year subscription to the Safe & Sound plan. The OnStar service
includes the General Motors Advanced Automatic Crash Notification (AACN)
system, making crash data available to emergency services to potentially
dispatch the appropriate life-saving personnel and equipment to crash
scenes faster. If the vehicle is in a crash that activates an air bag,
the OnStar system automatically notifies an OnStar advisor, who will check
on the occupants or summon emergency help if necessary. OnStar also can
assist authorities in locating a vehicle if it is reported stolen and
provides remote door-unlocking service (when the vehicle is equipped with
power locks).
