The 2013 Subaru Impreza STI hatchback remains a high-water mark for analog performance cars, combining a turbocharged boxer engine with a rally-bred chassis. If you're hunting for a used 2013 Subaru Impreza STI hatchback, you're looking at the final year of the wide-body GD/GR generation hatchback before Subaru dropped the five-door body style for the subsequent generation. It delivers 305 horsepower, symmetric all-wheel drive, and genuine everyday utility, but it also demands disciplined maintenance and a careful eye for past modifications.
Understanding what makes this specific model year tick requires looking past the spec sheet and into real-world ownership. While the car offers blistering grip and an engaging six-speed manual gearbox, it also carries well-documented engine vulnerabilities that catch second- and third-time buyers off guard. This guide breaks down exact technical specifications, real driving dynamics, common failure points, and what you need to inspect before handing over your cash.
Core Technical Specifications
The mechanical backbone of the 2013 STI is the legendary EJ257 2.5-liter turbocharged boxer-four engine. In stock form, it pushes out 305 horsepower at 6,000 rpm and 290 pound-feet of torque at 4,000 rpm. Power routes through a driver-controlled center differential (DCCD) six-speed manual transmission, sending drive to all four wheels via Subaru's Symmetrical AWD system.
The suspension layout relies on MacPherson struts up front and a double-wishbone setup in the rear, stiffened significantly compared to the base Impreza or standard WRX. Brembo performance brakes—four-piston front calipers and two-piston rears clamping ventilated discs—come standard. Curb weight sits at roughly 3,380 pounds, giving the hatch a solid, planted footprint on twisty tarmac.

Suspension and Handling Evolution
Subaru overhauled the STI's suspension tuning for the 2011 model year and carried those stiffer springs, thicker stabilizer bars, and revised bushing geometry straight into 2013. These changes dramatically reduced body roll compared to the soft-sprung 2008 launch models.
The hydraulic-assist steering rack is quick, offering a 15.0:1 ratio that translates to sharp turn-in. However, the steering column transmits plenty of road chatter, which drivers love on smooth canyon roads but find fatiguing on cracked urban asphalt. The DCCD system lets you manually lock or loosen the center diff split, shifting bias between a neutral 41:59 front-to-rear torque distribution and a locked 50:50 setup for loose gravel or snow.
Interior Comfort and Hatchback Practicality
The 2013 cabin leans hard into utilitarian function over luxury. Alcantara and leather-trimmed bucket seats hold you firmly in place during hard cornering, but the dashboard plastics feel dated and prone to squeaks and rattles.
The hatchback body style is where this car wins back points against its sedan sibling. With the rear seats up, you get 19 cubic feet of cargo space. Drop the 60/40 split-folding rear seats flat, and that expands to over 44 cubic feet, easily swallowing bicycles, track wheels, or camping gear. Rear passenger legroom measures 33.5 inches, which is tight for adults on long road trips but manageable for kids.
Common Reliability Issues and Buyer Warnings
Buying a used 2013 STI requires separating clean, enthusiast-owned cars from abused project builds. Because these cars invite modification, factory-stock examples command a heavy price premium.
Ringland Failure
The most notorious issue with the EJ257 engine is piston ringland failure, typically cylinder #4. It's caused by a combination of factory lean air-fuel ratios, high stock boost spikes, and poor fuel quality (detonation). If a previous owner installed an intake or exhaust without a proper ECU tune, the risk multiplies. Always insist on a pre-purchase compression and leak-down test. Healthy engines should show consistent compression across all four cylinders within a 10% variance.
Turbocharger and Oil Pickup Failures
The stock VF48 turbocharger is generally robust, but oil starvation can kill it instantly. The factory oil pickup tube has been known to crack at the bracket under heavy vibration. Upgrading to a reinforced aftermarket pickup is one of the first reliability mods owners perform.
Head Gasket Seepage
While multi-layer steel head gaskets largely solved the catastrophic external leaks of older EJ engines, the EJ257 can still weep oil or coolant externally around the rear of the cylinder heads as mileage climbs past 100,000 miles.
Modification Culture: What to Watch For
Walk through any local car meet and you'll spot modified STIs. While upgraded cat-back exhausts and upgraded sway bars are harmless, tread carefully around engine modifications.
- Stage 2 Tunes: If a seller claims the car has a "Stage 2" setup (downpipe, exhaust, boost controller, and ECU flash), ask for dyno sheets and proof of professional tuning from a reputable Subaru tuner (like Cobb Tuning or Perrin Performance). Generic off-the-shelf maps can run dangerous air-fuel ratios.
- Aero and Cosmetic Mods: Check behind aftermarket mudflaps and front lips for trapped moisture and rust, especially on cars driven in northern winter climates where road salt is prevalent.

Frequently Asked Questions
Is the 2013 Subaru Impreza STI hatchback reliable as a daily driver?
It can be, provided you check oil levels weekly and adhere strictly to 3,000-mile synthetic oil change intervals. It rides stiffly and demands premium fuel, making it an expensive daily commuter compared to standard economy hatchbacks, but it handles daily chores without drama if maintained.
How do I know if an STI has engine damage?
Look for blue or white smoke from the exhaust under acceleration or deceleration, oil pooling around the intercooler boots, and check engine lights related to misfires (P0301 through P0304). A professional pre-purchase inspection with a mechanic who specializes in turbocharged Subarus is non-negotiable.
What is the difference between the 2013 WRX and the 2013 STI hatchback?
The standard WRX uses a smaller 2.5-liter EJ255 engine making 265 horsepower, a five-speed manual transmission, narrower bodywork, and a simpler viscous-coupling center differential. The STI steps up to the EJ257 (305 hp), a bulletproof six-speed manual (TY85 transmission), DCCD, Brembo brakes, and a wider track with flared fenders.
Can I run regular 87 octane gas in an emergency?
No. Running lower-octane fuel under boost induces severe engine knock, which can shatter piston ringlands within minutes. Always run 91 or 93 octane gasoline.
Does the 2013 STI hatchback hold its resale value?
Yes. Because Subaru discontinued the STI hatchback body style after this generation, clean, unblemished 2013 models hold their market value remarkably well compared to sedans of the same era. Enthusiasts actively seek out the final hatchback iteration.
