The 2018 Chevrolet Sonic did not see a high-performance SS variant. Instead, the subcompact sedan and hatchback offers three gasoline engines without a high-performance model.
| Engine | Cylinders | Displacement | Aspiration | Fuel Type | Features | Power @ RPM | Torque @ RPM |
|---|---|---|---|---|---|---|---|
| LUW/LWE | 4 cylinder | 1.8L | Atmospheric | Gasoline | DOHC with Variable Valve Timing (VVT) and sequential MFI | 138 hp (103 kW) @ 6300 rpm | 125 lb-ft (168.8 Nm) @ 3800 |
| LUV | 4 cylinder | 1.4L | Turbocharged | Gasoline | DOHC with Variable Valve Timing (VVT) and sequential MFI | 138 hp (103 kW) @ 4900 rpm | 148 lb-ft (199.8 Nm) @ 1850 rpm (auto) / 2500 rpm (manual) |
As such, a subcompact, high-performance sedan or hatchback is not part of the Chevy lineup for the 2018 model year. However, the brand continues to offer two high-performance two-door vehicles — the Camaro and Corvette.
