Used 2018 Subaru WRX Sedan Trims Comparison

Base WRX models start with a 2.0-liter turbocharged four-cylinder engine (268 hp, 258 pound-feet of torque), a six-speed manual transmission and all-wheel drive. The standard equipment list also includes 17-inch wheels, performance tires, heated side mirrors, cloth upholstery, a rearview camera, 60/40-split folding rear seats, Bluetooth phone and audio connection, and a six-speaker media system with a 6.2-inch touchscreen, satellite and HD radio, CD player, USB and auxiliary inputs, and smartphone app integration.

The WRX Premium adds 18-inch wheels, foglights, a sunroof, heated front seats, windshield wiper de-icers, and a 7-inch touchscreen.

The Limited builds on that with LED headlights and foglights, automatic high beams, a 10-way power-adjustable driver seat, leather-trimmed upholstery, keyless ignition and entry, and an optional continuously variable automatic transmission (CVT) with paddle shifters.

Options for WRX Premium models with manual transmission include the 7-inch touchscreen, an upgraded Harman Kardon audio system, and a new Performance package that bundles Recaro front seats (including an eight-way power-adjustable driver seat), upgraded brake pads, and red-painted brake calipers. This package deletes the sunroof, however, in the interests of weight savings.

A manual-equipped WRX Limited is eligible for options including navigation, upgraded audio, blind-spot monitoring and rear cross-traffic alert systems, while Limited models equipped with the CVT can add Subaru's EyeSight system, which bundles features such as adaptive cruise control, automatic emergency braking, lane departure warning, automatic high beams, and adaptive ("bending") foglights that help illuminate corners and curves. The EyeSight system is not available with the stick shift, though.

STI models come equipped like the WRX Premium but with a bigger engine, 19-inch wheels, and no sunroof. The base STI adds a more powerful 2.5-liter engine engine (305 hp, 290 lb-ft), Brembo brakes, front and rear limited-slip differentials, and more aggressive suspension tuning. Options include Recaro sport seats, an eight-way power-adjustable driver seat, and keyless ignition and entry.

The STI Limited adds back the sunroof plus keyless ignition and entry, an eight-way power driver seat, blind-spot monitoring, rear cross-traffic alert and the premium audio system with navigation. The lone option is a low-profile trunk lip spoiler. EyeSight is not offered for the WRX STI.

Several dealer-installed options are available for the WRX and STI, including a performance exhaust (base WRX), an auto-dimming rearview mirror, short-throw shifter, carbon-fiber trim, unique shift knobs and interior lighting accents.
