2012 Chevrolet Sonic Hatchback
Both model displayed at the 2011 North American International Auto Show, there are the Chevrolet Sonic four-door sedan and a sporty five-door (hatchback). Its youthful, aggressive design is backed by turbocharged performance and agile ride and handling, combining to deliver an efficient, fun-to-drive small car.
Both delivers class-leading rear-seat roominess and cargo space. A variety of connectivity features enhance the driving experience. Its combination of great design, fun driving experience and the latest connectivity features create a serious competitor with a fun spirit.
Production of the Chevrolet Sonic begins later in 2011 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.
Chevrolet Sonic sedan and five-door models convey aggressive cues, including fender flares and motorcycle-inspired round headlamps, are blended with global design cues - a dual-element grille and round taillamps - for a design instantly recognizable as Chevrolet.
The five-door carries a tight, two-box shape with aggressive, diving feature lines, while the sedan's "notchback" profile has a more upscale and mature presence. At first glance, the five-door model looks like a three-door hatch because the rear door handles are discreetly located in the "C"-pillar area. The rear of the five-door continues with unconventional details, including exposed, motorcycle-inspired rear taillamps.
Chevrolet Sonic's quality detail include chrome grille surrounds and matte black honeycomb grille inserts on all models, while a range of large wheel sizes, including 17-inch alloy wheels, reinforces its sporty demeanor.
In interior of Chevrolet Sonic complements instrument cluster featuring a large, round analog tachometer set within an asymmetrical LCD readout, with a large digital speedometer display. The rear seats fold flat for carrying larger items. Front bucket seats are standard and heated front seats are available.
Additional interior highlights include:
- 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.
A range of wheel sizes is available, including 17-inch wheels and sport tires. Power-assisted front disc and rear drum brakes are standard, along with a four-channel antilock braking system. The four-sensor system - one at each wheel - incorporates electronic brake force distribution, which balances braking performance based on such factors as road conditions and the weight of passengers and/or cargo.
It is 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 new 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 estimated at 138 horsepower (103 kW) and 148 lb.-ft. of torque (200 Nm) between 1,850 rpm and 4,900 rpm.
The naturally aspirated Ecotec 1.8L engine has many of the same features of the Ecotec 1.4L turbo. 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 estimated at 135 horsepower (101 kW), along with 123 lb.-ft. of torque (167 Nm) at 3,800 rpm.
