Price and value

The K4 starts around $22,290, under the Impreza’s roughly $24,000 opening price, and it was named U.S. News Best Compact Car for the Money for 2026. At ALM Kia South, a new K4 also adds ALM VIP Club benefits and, on qualifying new vehicles, our Included Lifetime Warranty.

Awards, quality, and safety

The K4 was the Compact Car segment winner in the J.D. Power 2026 U.S. Initial Quality Study (second overall in the industry) and earned the 2026 IIHS Top Safety Pick+. The Impreza did not earn a 2026 Top Safety Pick, though Subaru’s larger models did.

Drivetrain and body style

This is the Impreza’s calling card: standard all-wheel drive on every model, which the front-wheel-drive K4 does not offer. The Impreza is hatchback-only, while the K4 gives you a sedan or a hatchback and adds an available 190-horsepower turbo the Impreza cannot match. Choose the Impreza for all-weather traction, the K4 for value, power, and body-style choice.

Warranty

The K4 carries the longer warranty: 5-year / 60,000-mile basic and 10-year / 100,000-mile powertrain, versus the Impreza’s 3-year / 36,000-mile basic and 5-year / 60,000-mile powertrain.

The bottom line for Union City shoppers

Choose the Impreza if standard all-wheel drive is a must. Choose the K4 for the lower price, the 190-horsepower turbo, the J.D. Power and IIHS honors, the longer warranty, and the ownership perks at ALM Kia South. Browse our K4 inventory or contact our team to compare them in person.
