Chevrolet unveiled the production model of the 2006 HHR, a unique
vehicle that combines styling and interior adaptability to create a
vehicle suited to all lifestyles. Chevy introduced the HHR at the
2005 Greater Los Angeles Auto Show, the spiritual home of the custom
The HHR has a distinct design that fuses elements of the 1949 Chevy
Suburban – the original utility vehicle – and the SSR roadster. It
is built on the same solid platform as the new Chevy Cobalt. The HHR
will be available in the second half of 2005.
“The HHR is what you want it to be, whether you’re hauling band
equipment around the country or hauling your friends across town,”
said Lori Queen, GM vehicle line executive for small car. “With its
unmistakable styling and innovative features, the HHR is further
proof that there is a new spirit at Chevrolet.”
With its overall length of 174.5 inches (4472 mm) and a cargo
capacity of approximately 63.1cubic feet (1787 liters), the
five-passenger HHR has easy-to-maneuver dimensions and room for just
about any lifestyle interest. Its reconfigurable interior with
clever storage solutions accommodates everything from groceries to
HHR rounds out Chevrolet’s small-vehicle strategy that began last
year with the successful Aveo – a vehicle which recently claimed the
leadership position in its segment after just nine months on the
market – and continues this year with Cobalt.
HHR comes well equipped
from the factory with two model levels: LS and LT. The LT also comes
in two packages – 1LT and 2LT. The LS and 1LT are powered by an
Ecotec 2.2L four-cylinder rated at 140 horsepower (104 kw) and 150
lb.-ft. of torque (207 Nm). An Ecotec 2.4L four-cylinder is standard
in the 2LT and is available in the 1LT; it delivers 170 horsepower
(126 kw) and 170 lb.-ft. of torque (235 Nm). A five-speed manual
transmission is standard and an electronically controlled four-speed
automatic is available in all models.
Both LS and LT HHR models include standard features such as air
conditioning, power windows and door locks, six-speaker CD stereo,
and remote keyless entry. Additional product highlights include:
enhanced-performance audio system with subwoofer
Large power sunroof
XM Satellite Radio
tank provides more than 400 miles cruising range
16-inch and 17-inch
(standard with automatic transmission)
The 1LT model also
includes a standard MP3 player, six-way power seat with power
lumbar, and a satin exterior finish. Bright chrome exterior trim and
a bright exhaust tip are available. ABS and traction control are
available (traction control only available with automatic
HHR 2LT includes
standard features that include ABS, fog lamps, bright exhaust tip,
leather-wrapped steering wheel and shifter, the Pioneer sound system
with subwoofer, 17-inch wheels, FE3 sport suspension and a bright
chrome exterior trim. Heated leather seats also are available on
both LT packages.
HHR is a four-door
vehicle with a rear touch-pad liftgate. Its high roof evokes the
look of the innovative 1949 Chevy Suburban, while other exterior
cues carry the expressive attributes of the SSR roadster – all
unmistakably Chevy traits.
Like the SSR, the HHR features deep-draw, flared fenders which tuck
in at the rockers for a solid, firmly-planted stance. A one-piece,
stamped metal hood is reminiscent of the ’49 Suburban’s heritage and
is evidence of precise assembly quality. More quality touches are
found in the single-cavity headlamp design, which incorporates
jeweled lighting effects, as well as a flared, twin-taillamp design
in the rear that creates a look that is half street machine and half
vintage Corvette. Stamped door and window appearances with a
one-piece wraparound molding contribute to the clean, detailed
design and are uncommon in contemporary vehicles. The HHR’s rear
window is flush with the body side.
The outside mirrors are integrated into the overall design theme for
a more custom appearance, and the available integrated roof racks
are designed to retain the HHR’s overall aesthetic. The HHR also
incorporates contemporary Chevy styling cues, including a prominent
cross-grille bar with a Bowtie logo.
A variety of expressive exterior colors will be available.
Haul, store, pack more
Like the rest of the
vehicle, the HHR’s interior combines the reassuring high visibility
and cargo flexibility of an SUV with the comfort, appointments,
driving ease and ergonomics of an upscale sedan. The high roof
provides excellent headroom and creates a more open, airy
environment, while the instrument cluster carries the heritage theme
of the vehicle.
The HHR’s interior evokes a feeling of roominess and an upscale aura
is created by detailed, jewel-like instrument displays and chrome
accents. Interior color combinations feature darker colors on upper
sections of the interior and lighter colors for lower sections.
Quality also is conveyed in the tailored seats, which provide firmer
support, sculpture and plenty of comfort for long drives.
HHR also has standard air conditioning, providing comfortable levels
of airflow, cooling capability and reduced cool-down time. The
system is designed to provide efficient side-window defogging and
enhanced rear-window defogging.
Complementing the HHR’s comfortable and expressive interior is a
highly adaptable cargo system, which maximizes storage capability
with a host of clever and useful configuration options, including:
The front passenger
seat folds fully flat, extending the total load length from the
liftgate to the instrument panel.
The center armrest
of the front seats is integrated into the seat back frame, so it
is out of the way when pivoted into a stowed position; a
characteristic of trucks and SUVs.
The rear seats have
a 60/40-split, which fold to form a flat load surface in
conjunction with the folded front passenger seat. The 60-percent
side was thoughtfully positioned on the passenger side, enabling
wider objects to be placed in the vehicle securely.
The cargo area in the
rear also is thoughtfully designed:
It provides a
continuous flat load floor when the rear seats are folded down.
The floor conceals a
5-inch-deep recess bin; the spare tire is located beneath the
The primary load
floor can become a shelf when raised and mounted approximately 2
feet higher – the shelf can be mounted level or at a 45-degree
angle to provide quick access to the cargo beneath it when the
liftgate is opened.
Two large storage
bins are found forward of the load floor, nested behind the rear
seat, and plastic bag holders are conveniently located on the
rear compartment bin.
HHR relies on the
renowned Ecotec family of technologically sophisticated inline
four-cylinder engines, which balances usable power with fuel and
emissions efficiency. Both the 2.2L engine and 2.4L engines in the
HHR have distinct performance and hardware differences, but share a
basic structure and construction that includes:
camshafts (DOHC) and four valves per cylinder
counter-rotating balance shafts for operational smoothness
roller-finger follower valvetrain with hydraulic lash adjusters
accessories, which reduce or eliminate traditional sources of
noise and vibration
transmission mount to reduce noise and vibration
GM Oil Life System,
which can reduce the frequency for oil changes
oil filter housing, which eliminates the need to crawl under the
vehicle to perform oil changes and eliminates throwaway oil
filter cans that retain used oil
located close to exhaust manifold to speed catalyst “light off,”
reducing hydrocarbon emissions
HHR’s Ecotec engines
also benefit from features designed to reduce noise and vibration.
The pistons, for example, have a polymer coating and skirt design
that reduces noise during cold starts, while a new, two-layer
acoustic engine cover is tuned to reduce noise. NVH is reduced with
a new automatic tensioner that maintains optimal tension on the
Transmissions include a standard Getrag F23 five-speed manual
transmission or an available Hydra-Matic 4T45-E electronically
controlled four-speed automatic, which are available with both
engines. The F23 five-speed manual transmission delivers smoothness
and durability, with all gears – including reverse – featuring
synchronization. Final gearing of the transmission varies between
2.2L and 2.4L applications to optimize the performance of both.
The available 4T45-E is a smooth-shifting, highly durable automatic
transmission. Like the F23 manual transmission, there are
calibration differences to optimize the performance of 2.2L-equipped
models and 2.4L-equippped models.
Strong body structure provides a
HHR is built on the same
robust GM Small Car structure as the recently introduced Chevy
Cobalt. This lower-dominant structure is designed with strength in
the lower portions of the chassis, contributing to an overall
feeling of rigidity and superior noise and vibration
characteristics. In fact, with the use of materials such as Quiet
Steel laminated panels in the plenum, the HHR is expected to offer
the quiet, high-quality NVH traits of a more expensive car.
Extensive use of high-strength steel and ultra-high-strength steel
in key structural components, including ultra-high-strength steel
rocker panels and cross-car reinforcing beam, bolsters the vehicle’s
rigid feel while providing additional side-impact support. The
cockpit “safety cage” provides load-carrying protection and, along
with laser-welded blanks used in the door frames, front doors and
rear doors, contributes to the HHR’s excellent NVH characteristics
and precision build quality.
HHR’s uses a MacPherson
strut front suspension design, along with a semi-independent,
torsion beam rear suspension and five-lug wheels. Two suspension
systems are available: FE1 suspension standard on LS and 1LT, with
an FE3 suspension standard on LT models. The FE1 suspension is tuned
for a softer ride and includes 16-inch wheels, while the FE3
provides sportier handling traits and offers standard 17-inch wheels
and monotube shocks, which provide better ride and handling.
All models are equipped with rack-and-pinion steering with electric
power steering (EPS) – a speed-sensitive, variable-effort system
that is tuned to match the performance characteristics of two
separate suspension settings. EPS eliminates the use of an
engine-driven power steering pump, as well as the corresponding
fluid reservoir and plumbing, reducing both fuel consumption and the
potential source of an environmental contaminant.
Brakes consist of large front discs and rear drums, with ABS and
traction control standard on 2LT models (traction control only
available with automatic transmission) and available on LS and 1LT
