Does an HHR have a turbo?
Only the Chevrolet HHR SS model came with a factory turbocharged engine; standard HHR trims use naturally aspirated four-cylinders. This article explains which HHRs had forced induction, how to identify them, and what buyers should know.
Overview of the HHR engine lineup
GM offered a mix of naturally aspirated four-cylinders for most HHRs, with turbocharged power reserved for the high-performance variant. The following outlines the core engine options found across the model run.
Turbo vs NA: Quick distinction
The turbocharged option is exclusive to the HHR SS. Regular trims rely on naturally aspirated engines, so turbo presence is a key differentiator for buyers and owners.
Key engine options by trim and year include:
- 2.2-liter Ecotec inline-4 (NA): Used in early and lower-trim HHRs; typically around 140–143 horsepower and modest torque; not turbocharged.
- 2.4-liter Ecotec inline-4 (NA): Appeared in some mid-range HHRs; around 172 horsepower and 162 lb-ft of torque; not turbocharged.
- 2.0-liter turbocharged inline-4 (turbo): Exclusive to the HHR SS; about 260 horsepower and roughly 260 lb-ft of torque; introduced in the latter years of the model run (roughly 2009–2011).
Notes: The HHR was discontinued after the 2011 model year. Turbo availability is restricted to the SS variant; regular HHR trims do not come with factory turbocharging. Aftermarket turbo kits exist but are not GM factory offerings for the HHR.
How to tell if your HHR has a turbo
Verifying whether a specific HHR has a factory turbo involves checking badges, engine details, and original documentation. The turbo-equipped SS variant displays distinctive clues beyond raw horsepower figures.
Indicators to look for:
- Badging: An "SS" badge on the exterior and often a "Turbo" designation on the engine cover or under-hood labels.
- Engine bay: Visible turbocharger housing and intercooler piping; the turbo setup is typically more conspicuous than NA engines.
- VIN/window sticker: The vehicle’s documents will indicate the engine option (often listing a 2.0L turbo engine for SS models).
- Performance cues: The SS usually offers sport-tuned suspension and stronger acceleration characteristic of a turbocharged powertrain.
Bottom line: If you want a turbocharged HHR from the factory, target an SS; non-SS HHRs are not turbocharged unless modified after purchase.
Buying considerations for turbo vs non-turbo
The choice between turbocharged and naturally aspirated HHRs involves trade-offs in performance, maintenance, and cost. The following considerations help buyers decide.
- Performance vs fuel economy: The SS delivers significantly more power, but fuel economy is typically lower than NA trims.
- Maintenance and potential turbo issues: Turbo engines can require more careful maintenance (oil quality, intercooler reliability, boost control). Repairs specific to turbo components can be pricier.
- Insurance and resale: Turbo models can carry higher insurance costs; resale value varies with maintenance history and market demand.
- Warranty coverage: Factory turbo components may have specific warranty terms; base engine components have standard GM powertrain coverage.
Conclusion: If you value performance and the HHR badge, look for an SS; if you prioritize fuel efficiency and lower upkeep, a non-turbo trim may be preferable. Always verify the engine option via the window sticker or VIN before purchase, and be aware that aftermarket turbo setups exist but are not factory GM equipment for the HHR.
Summary
In short, the HHR only uses a factory turbo in the SS model. All other trims are naturally aspirated. To ensure you’re getting turbocharged performance, verify the presence of the SS badge, confirm the engine option on the window sticker or via the VIN, and beware of non-factory modifications when evaluating a used HHR.
