For 2018, the biggest changes to the Subaru WRX STI are invisible to the naked eye

Subaru released a brand-new Impreza late last year, but the WRX STI (and the less powerful WRX) won’t be replaced until 2020 at the earliest. In the meantime, the Japanese brand has updated both models inside and out to keep them looking fresh.

Although exceedingly minor, the visual modifications help bring the WRX and the WRX STI in line with Subaru’s newest design language. The front end receives a smaller grille, and a redesigned bumper with bigger air dams, while the rear end carries on all but unchanged. Select models benefit from pivoting headlights that illuminate curves, and the WRX STI is available with 19-inch alloy wheels for the first time in the nameplate’s history.

Many of the more important updates are invisible to the naked eye. Subaru has comprehensively updated both models’ suspension system to obtain better stability and a more comfortable ride, upgraded the brakes, and made the steering system more responsive. The STI’s Driver Controlled Center Differential (DCCD) is now fully electronic, which speeds up its response time. In other words, the 2018 models should be better to drive than the outgoing 2017 models.

Inside, the passengers are treated to a bigger information screen on the dashboard, and a larger touchscreen that displays Subaru’s Starlink infotainment system. Thicker glass, revised door seals, and additional sound-deadening material make both models easier to live with on a daily basis.

There are no major mechanical modifications to report under the hood. The WRX continues to offer a turbocharged, direct-injected 2.0-liter four-cylinder engine rated at 268 horsepower and 258 pound-feet of torque. The WRX STI benefits from a 2.5-liter flat-four tuned to produce 305 horses at 6,000 rpm and 290 pound-feet of twist at 4,000 rpm with the help of a turbocharger.

Both models come standard with a six-speed manual transmission and Subaru’s proven symmetrical all-wheel drive system. The WRX is optionally available with a continuously variable transmission (CVT) that features a built-in manual mode with pre-programmed virtual gears, but WRX STI buyers who want two pedals are out of luck.

The 2018 Subaru WRX and WRX STI will reach showrooms in the spring. Pricing information will be published in the weeks leading up to their on-sale date.

Subaru turned its WRX STI into a 600-horsepower monster that eats supercars
Subaru WRX STI Typa RA NBR Special

It may be based on a humble economy car, but this Subaru WRX STI just lapped one of the world's most grueling racetracks as fast as some elite supercars.

A specially modified version of the WRX STI recently lapped Germany's 12.8-mile Nurburgring Nordschleife in 6:57.5. Subaru claims that's a record for a sedan, and at any rate it puts the car in some elite company. The Subaru is virtually tied with the mighty Porsche 918 Spyder, and just a few seconds behind the Lamborghini Huracán LP640-4 Performante, which did a 6:52.01 lap.

Subaru’s 2018 Outback continues its one-wagon fight against SUVs
2018 Subaru Outback

The Subaru Outback has achieved the near-impossible, surviving the onslaught of SUVs that killed nearly every other wagon. Thanks to standard all-wheel drive and some plastic body cladding, Subaru is able to market the Outback as an SUV alternative. It has made for a profitable niche, but how does Subaru improve on that success?

Debuting at the 2017 New York Auto Show, the 2018 Subaru Outback gets some of the same styling tweaks as the 2018 Legacy that debuted in Chicago in February, plus more tech features. Overall, these make for relatively small changes to the current-generation Outback, which has been on sale since the 2015 model year. Will it be enough to keep Subaru's sales champ sharp?
