The all-new 2012 Sonic is a small car with a large array of features and 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. And each delivers class-leading rear-seat roominess. A variety of connectivity features enhance the driving experience.
Power-dense four-cylinder engines, including an Ecotec 1.4L turbo, are offered in the Sonic 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, which received a $545-million investment in upgrades and retooling, and will help restore approximately 1,000 jobs in the metropolitan Detroit area. That makes it the only small car built in the United States.
; 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
; A range of large wheel sizes, including 17-inch alloy wheels.
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.
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. Several transmissions are available: a five-speed manual and six-speed automatic with the 1.8L , along with a six-speed manual and six-speed automatic 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
; The rear suspension consists of a semi-independent, torsion beam axle-mount
compound link-type design – featuring a tubular V-shape beam – with gas-
; 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, eliminates the need for steering fluid
and a pump needed with hydraulic systems, and 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 antilock 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
; LATCH (Lower Anchors and Tethers for CHildren) child seat attachment
system, which is included in all second-row seating positions. ; Tire pressure monitoring system, 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.
Sonic is offered with OnStar on all models. 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 Camaro 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.
