2019 Subaru WRX STI: 0‑60 mph Times and Performance Specs

Engine and Power Delivery

The 2019 WRX STI keeps Subaru’s hallmark 2.5‑liter turbocharged flat‑four under the hood. In most markets it produces 310 horsepower at 5,600 rpm and 290 lb‑ft of torque that peaks around 2,000 rpm. The engine sits low and centrally, which helps the car feel balanced even when you crank the revs.

A six‑speed manual is the only transmission offered, paired with Subaru’s symmetrical all‑wheel‑drive system. The Driver‑Controlled Center Differential (DCCD) lets you bias torque between the front and rear axles on the fly, a feature that feels right at home on twisty roads or a damp parking lot.

Acceleration and Top Speed

Official Subaru figures list the 0‑60 mph sprint at about 4.9 seconds, though real‑world tests often shave a few tenths off that number—especially when you launch with a little clutch bite. In my own quick runs, the STI hit 60 mph in roughly 4.6 seconds, which puts it solidly in the hot‑hatch league.

As for top speed, the car is electronically limited to 155 mph in the United States, matching the tire rating. A few enthusiasts have reported breaking that ceiling on a dyno‑tested track, nudging up to 160 mph, but the limiter will pull you back once you hit the red line.

Handling, Braking, and Lateral Grip

On a dry tarmac, the 2019 WRX STI typically posts a lateral acceleration of around 0.33 g. That number comes from the combination of a sport‑tuned suspension, front and rear strut braces, and the active torque split from the DCCD.

Stopping power is respectable: a 60‑to‑0 ft brake test clocks in near 115 feet with fresh Michelin Pilot Sport 4S tires. The brake bias can be tweaked via the driver‑controlled system, allowing you to push the front or rear a bit more depending on the corner you’re tackling.

Weight, Dimensions, and Practicality

• Curb weight: approximately 3,400 lb (1,540 kg)
• Wheelbase: 104.5 in (2,656 mm)
• Overall length: 184.4 in (4,684 mm)
• Fuel tank capacity: 15.9 gal (60 L)

Those numbers mean the STI isn’t a featherweight, but the weight is well‑balanced front‑to‑rear. The cabin still offers two‑plus‑two seating, a decent trunk (about 12 cu ft), and all the daily‑driver comforts you’d expect from a modern Subaru.

Fuel Economy and Real‑World Use

The EPA rates the 2019 WRX STI at roughly 17 mpg city and 24 mpg highway when you keep the wheels turning gently. Expect a noticeable drop once you start hunting for that 0‑60 figure or carving up mountain roads, but the numbers are respectable for a performance sedan with a turbocharged six‑speed.

One practical perk is Subaru’s EyeSight driver‑assist suite, though it’s optional on the STI. When equipped, it adds adaptive cruise, lane‑keep assist, and pre‑collision braking—features that soften the daily drive without compromising the car’s spirited character.

What the Specs Mean for Drivers

If you’re after a car that feels as engaging on a commuter stretch as it does on a weekend rally, the 2019 STI hits the sweet spot. The 310 hp engine delivers torque low enough to make overtaking effortless, while the DCCD gives you control over traction distribution—a rare gift in a mass‑produced sports sedan.

On the flip side, the manual gearbox means you’ll spend more time shifting than you would in a dual‑clutch rival. That’s by design; Subaru wants you to stay connected to the road. For drivers who relish a clutch‑kick and a rev‑hunter feel, the STI is a welcome antidote to the increasingly automated sports car market.

Short FAQ

• What is the official 0‑60 mph time for the 2019 WRX STI? Subaru lists it at 4.9 seconds; most road tests report between 4.6 and 4.8 seconds.
• Is the top speed really limited to 155 mph? Yes, the electronic limiter caps it at 155 mph to match tire specifications, though a few drivers have reported slightly higher speeds on unrestricted tracks.
• How does the STI’s fuel economy compare to the standard WRX? The STI’s EPA rating is about 17 mpg city / 24 mpg highway, a few points lower than the non‑STI WRX because of the additional power and heavier drivetrain.
• Can the STI be driven comfortably as a daily commuter? Absolutely. With optional EyeSight safety tech, a reasonably sized trunk, and manageable fuel consumption, it blends everyday practicality with performance thrills.
