The new 2012 "Sonic" (still called "Aveo" in most other markets outside of North America) debuted at the 2011 NAIAS (North American International Auto Show) in Detroit.

Sonic’s highlights include:
- Available efficient Ecotec 1.4L turbo engine rated at an estimated 138 horsepower (103 kW) – 18 horsepower (14 kW) more than Ford Fiesta – that delivers competitive fuel economy. It’s the same engine used in the Chevrolet Cruze in a smaller, lighter package for a greater feeling of performance
- Standard Ecotec 1.8L engine paired with five-speed manual or six-speed automatic transmissions
- Ecotec 1.4L turbo available with a six-speed manual transmission
- Ride and handling tuned by Chevy Corvette engineers; standard electronic power steering and StabiliTrak electronic stability control with rollover sensing
- Sedan model offers segment-best trunk capacity that is greater than most compact cars; hatchback and sedan offer better rear-seat roominess than Ford Fiesta. With a rear seat that folds nearly flat, the Sonic hatchback has greater cargo capacity than Fiesta
- Connectivity includes OnStar with six months of Turn-by-Turn navigation. Available features include XM Satellite Radio, USB and Bluetooth functionality and MyChevrolet mobile application with OnStar MyLink vehicle connectivity
- Remote start, heated front seats and sunroof, all rarities in the segment
- Comprehensive safety features include 10 standard air bags, antilock brakes, electronic brake force distribution, brake assist and OnStar with Automatic Crash Response.
Cruze-based powertrains
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 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.
EDIT: a Sonic diesel option hasn't been announced, though the European 2012 Aveo (Sonic) is available with a 1.3L turbodiesel.
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 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. Features include:
- Low-mass hollow-frame cast iron block
- Dual overhead camshafts with variable valve timing
- Chain-driven cams
- Roller-finger camshaft followers
- Piston-cooling oil jets and integrated oil cooler
- Variable-flow oil pump
- 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 estimated at 135 horsepower (101 kW), along with 123 lb.-ft. of torque (167 Nm) at 3,800 rpm.
Engineered for agile, athletic ride and handling
The Sonic brings agility and a fun-to-drive feel that is rare in the segment. Engineers who also work on the Corvette tuned the Sonic’s confident ride and handling, giving it a more direct and athletic 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, and a semi-independent, torsion beam axle-mount compound link-type rear suspension – featuring a robust, 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 excellent balance.
Electronic power steering is standard 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. Its rigidity enabled engineers to tune the ride and handling more precisely. Sonic’s unique “flat top frame” cradle, for example, 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. 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.
