The HHR has easy access and a flexible cargo area, with split rear seats that fold to create a generous and flat load floor. The ride is comfortable enough and handling is secure, though not agile. Tall gearing and an unresponsive automatic transmission leave the HHR feeling lethargic in everyday driving, and we still only measured 24 mpg overall from its noisy 2.4-liter engine. Short windows and thick roof pillars impair visibility and interior quality is unimpressive. Thankfully, window controls were relocated to the doors starting with 2009 models. Both engines received a power boost for 2007 and 2011 was the last year.
