Highlights
The all-new 2012 Sonic is a small car with a large array of
amenities. It is offered in two body styles: a four-door sedan and a
five-door, each with distinctive design elements, including
motorcycle-inspired round headlamps. Sonic also delivers class-leading rear-seat
roominess and connectivity features that enhance the driving
experience.
The Sonic is equipped with power-dense four-cylinder engines,
including an Ecotec 1.4L turbo, and it is designed to be one of the safest
vehicles in the segment, with 10 standard air bags.
Production of the Sonic takes place at the General Motors Orion
Assembly Center in Michigan, making it the only subcompact built in the United
States. The plant received a $545-million investment in
upgrades and retooling, and will help restore approximately 1,000 jobs in the
metropolitan Detroit area.
Sonic design
- Two distinct body styles: four-door sedan and
five-door.
- A wide, planted stance, with wheels-at-the-corners
proportions, conveys performance. Progressive, raked body lines suggest
movement even when the car is stationary.
- Motorcycle-inspired round headlamps and
taillamps.
- Rear door handles on the five-door are located in a
C-pillar area, suggesting the style of a three-door hatch.
- Chrome grille surrounds and matte black honeycomb grille
inserts on all models.
- A range of large wheel sizes, including 17-inch alloy
wheels.
Sonic interior
Sonic's cabin complements the motorcycle-inspired exterior with
a detailed instrument cluster featuring a large, round analog tachometer set
within an asymmetrical LCD readout, with a large digital speedometer
display.
- The mid-instrument panel surface is available in two
colors (dark titanium and brick) and flows seamlessly into the upper doors, with
premium low-glass finishes.
- The automatic shift knob has a "cobra head" design,
while the manual shifter has a chrome-finished knob.
- Tubular outboard climate outlets protrude from the
instrument panel surface.
- The interior includes storage compartments in the center
stack and doors.
- The rear seats fold virtually flat for carrying larger
items.
- Front bucket seats are standard and heated front seats
are available.
Sonic powertrain
Chevrolet Sonic models are powered by efficient, power-dense,
small-displacement engines, including the Ecotec 1.4L turbo and the Ecotec 1.8L
- the same engines used in the Chevrolet Cruze. Three transmissions are
available: a five-speed manual and six-speed automatic with the 1.8L and a
six-speed manual with the 1.4L turbo.
- The Ecotec 1.4L turbo's power ratings are 138 horsepower
(103 kW) and 148 lb.-ft. of torque (200 Nm) between 1,850 rpm and 4,900
rpm.
- The wide rpm range for the maximum torque - a specific
trait of turbocharged engines - helps the engine deliver a better driving
experience and performance.
- Premium design elements give the engine world-class
smoothness and durability, including a low-mass hollow-frame cast iron block,
dual overhead camshafts with variable valve timing, chain-driven cams and
roller-finger camshaft followers, piston-cooling oil jets and integrated oil
cooler, a variable-flow oil pump and an electronically controlled
thermostat.
- The 1.4L's turbocharger is integrated within the
exhaust manifold, for reduced weight and greater packaging flexibility in
small vehicles. A reinforced crankshaft and stronger connecting rods deliver
additional strength to support the engine's pressurized power and torque over a
wide rpm band.
The naturally aspirated Ecotec 1.8L engine has many of the same
features of the Ecotec 1.4L turbo.
- It is a compact and durable four-cylinder engine
designed for low maintenance, low emissions and fuel efficiency.
- Its two-stage variable intake manifold allows
approximately 90 percent of peak torque to be available from 2,400 rpm to 6,500
rpm.
- It is rated at 138 horsepower (103 kW) along with 125
lb.-ft. of torque (170 Nm) at 3,800 rpm.
Sonic chassis and suspension
Engineers who also work on the Corvette tuned the Sonic's ride
and handling, giving it a more direct feel, while balancing the vehicle for the
broad range of driving conditions in North America.
- All models feature a MacPherson strut front suspension
with coil springs and stabilizer bar.
- The rear suspension consists of a semi-independent,
torsion beam axle-mount compound link-type design - featuring a tubular V-shape
beam - with gas-charged shocks.
- The front and rear tracks are identical at 59.4 inches
(1,509 mm), for well-planted stability and balance.
- Electronic power steering is standard, and eliminates the
need for steering fluid and a pump needed with hydraulic systems. It
features a wear compensator that continually adjusts the system interaction
with the steering gear to ensure precise steering action over the life of the
system.
- Sonic's body structure is designed to be one of the
stiffest in the segment and its rigidity enabled engineers to tune the ride and
handling more precisely.
- A unique "flat top frame" cradle assures optimal
stiffness in the front chassis portion of the vehicle.
- The rear axle is essentially a straight axle without
contour for packaging restraints and reduced noise, vibration and harshness.
- A range of wheel sizes is available, including 17-inch
wheels and sport tires.
Sonic safety and crash-avoidance features
The Sonic is designed to help drivers avoid crashes, while
protecting the occupants in the event a crash occurs.
- Ten standard air bags include side curtain air bags,
which provide head protection for outboard passengers in the event of a
side-impact or rollover crash.
- StabiliTrak electronic stability control system helps
reduce the risk of rollover crashes by keeping the vehicle in the driver's
intended path by applying throttle, braking or a combination of
both.
- Power-assisted front disc and rear drum brakes are
standard.
- Four-channel anti-lock braking is standard and
incorporates electronic brake force distribution, which balances braking
performance based on such factors as road conditions and the weight of
passengers and/or cargo.
- Pretensioners minimize forward movement during a
collision, and are standard on the front safety belts. Load-limiting retractors
cinch the belt more tightly.
- LATCH (Lower Anchors and Tethers for Children) child
seat attachment system, which is included in all second-row seating
positions.
- Tire pressure monitoring system is standard on all
models.
- Strong body structure to absorb crash energy and provide
a protective "safety cage" around occupants. More than 60 percent of the body
structure is composed of advanced steels.
OnStar details
All Sonic models are equipped with OnStar. It uses GPS and cellular
phone technology to automatically call for help in the event of crash. OnStar
subscribers also can use the service to be Good Samaritans by sending help to
other motorists, and to call for help in other non-crash emergencies.
- OnStar is the leading provider of in-vehicle safety,
security and information services in the United States and Canada.
- Six months of complimentary OnStar Directions and
Connections service with Turn-by-Turn Navigation for easier route guidance
on all Sonic models. The feature is easy to use because all directions are
sent to the car by an advisor, without the need to stop. Turn-by-Turn can be
cost-effective, since map updates and aftermarket navigation systems are not
needed.
- Stolen Vehicle Assistance helps police track the
vehicle.
- MyChevrolet mobile app gives owners remote access to
vehicle OnStar features including door unlock, vehicle diagnostics, emergency
assistance and more.
