Subaru Impreza 2007-2011 Specifications

The 2007-2011 Subaru Impreza offers two main engine options: a 2.5L naturally aspirated 4-cylinder engine producing 170 hp and 170 lb-ft of torque, and a 2.5L turbocharged 4-cylinder engine in the WRX and STI models, producing 224 hp (265 hp in the STI) and 226 lb-ft of torque (290 lb-ft in the STI). The turbocharged engines provide significantly higher performance, while the naturally aspirated engine focuses on reliability and fuel efficiency.

The Impreza comes with a 5-speed manual transmission as standard. An optional 4-speed automatic transmission is available for the naturally aspirated models. The WRX and STI models offer a 5-speed manual (WRX) or a 6-speed manual (STI), with no automatic option for these performance trims.

Standard safety features include dual front airbags, side-impact airbags, anti-lock brakes (ABS), and electronic brake-force distribution (EBD). Optional features include stability control, traction control, and a rearview camera. The Impreza also features a reinforced ring-shaped reinforcement frame for enhanced crash protection.

The 2007-2011 Impreza achieves an EPA-estimated 20-24 mpg city and 27-32 mpg highway, depending on the engine and transmission. This is competitive with similar compact cars like the Honda Civic and Toyota Corolla, though the turbocharged models have lower fuel efficiency due to their higher performance.

Subaru recommends oil changes every 3,750 miles or 3 months for turbocharged models and every 6,000 miles or 6 months for naturally aspirated models. Other maintenance tasks, such as air filter replacement and brake inspections, should be performed every 15,000-30,000 miles, depending on driving conditions.

Standard features include air conditioning, power windows, and a CD stereo. Optional features include a sunroof, leather upholstery, heated seats, and a premium audio system. The WRX and STI trims add performance-oriented features like sport-tuned suspension, larger wheels, and Brembo brakes.

The Impreza offers 11.3 cubic feet of trunk space in the sedan and 19.0 cubic feet in the hatchback. Passenger space is competitive, with 92.6 cubic feet of interior volume. This is comparable to the Honda Civic and Mazda3, though the Impreza�s all-wheel-drive system may slightly reduce interior space.

The Impreza is not designed for heavy towing, with a maximum towing capacity of 1,500 lbs when properly equipped. Payload capacity varies by trim but is generally around 900-1,000 lbs. For heavier towing needs, a larger Subaru model like the Outback is recommended.
