Buying a Subaru WRX STI may seem like an almost out-of-reach goal. Many new models sell for well over $40,000, making the idea of driving off the lot an expensive daydream. It may seem like a better idea to settle for the Subaru WRX. The WRX has a decent drive, about 35 fewer horsepower, and an optional CVT by rights. Though it may seem like a better idea, a third option presents itself. The 2016 Subaru WRX STI. 2016 is removed from the model split of 2015, so some bugs have been worked out. Does the discount in price worth the increase in age?

Each sports car features the classic AWD Subaru is known for. The boxer engine platform is also present in each, another well-known trademark of the Subaru brand. Though five years separate the 2021 and 2016 models, the 2016 STI ultimately proves that age is just a number.

9 The Difference Is In the Displacement

Subaru's AWD sports cars don't share the same engine. In fact, the 2021 Subaru WRX has a half-liter smaller displacement compared to its bigger brother. The 2.0L turbocharged boxer-four is capable of 268hp in the WRX, but that peak horsepower comes in 5,600RPM.

The 2016 Subaru WRX STI makes good use of the extra displacement by putting out 305hp. Though it is more horsepower, the peak doesn't kick in until 6,000 rpm. Each engine is a DOHC design, but the STI has undoubtedly more power!

8 Shifting Made Easy

For 2021, the Subaru WRX came in two transmissions. Of course, the six-speed manual is still available, and it joins the Sport Lineartronic Transmission, which offers six and eight-speed manual modes. The automatic transmission provides the WRX feel without the need for precision shifting.

Though the automatic CVT only comes on the WRX, the STI is all sports car with an upgraded version of the transmission found on manual WRX models. This close-ratio version of the manual transmission allows more torque to be distributed through the powerband.

Luckily the 2021 model isn't as ugly as the 2022 model, but the clear winner is the WRX STI. The 2021 WRX has 17-inch alloy wheels, silver WRX badging, and a pretty minimalist lip spoiler on the trunk. The WRX is more of the road-friendly style sedan that Subaru produces.

The WRX STI hasn't gone through significant changes since the 2015 model split, and that is certainly true for the 2016 model. Featuring 18-inch rims, red STI badging, and the iconic large wing spoiler. Additionally, some models featured additional trim around the body paneling, and if it isn't there, to begin with, aftermarket parts always look good!

Subaru upgraded the interior of the WRX for the 2021 model. The six-speaker sound system plays through Harmon-Kardon speakers available on the limited trims. Additionally, both cars sport split screens for gauges up top and a 7-inch infotainment system.

It is possible to find STI models with the Recaro seats installed, but they're not critical to the car. The interior is quite similar to the WRX. There are six speakers throughout the cabin, so not the nicest in terms of audio. The backup cam is adequate and displayed on the dash's split-screen gauge display.

With the half-liter displacement difference, there are significant differences in the gas mileage in these two sports cars. The 2021 WRX features an excellent daily driver rating of 20mpg in the city and 27 on the highway. This leads to a max range of 429 miles before a fill-up.

The extra power in the STI comes at a premium. Premium fuel, that is, as both cars take 91 octane to fill their almost 16-gallon tanks. The STI has a city rating of 17mpg and 23 on the highway for a max range of 365 miles. The difference can add up when on the road constantly!

4 Maintenance Costs and Issues

It's no fun when the car is in the shop. Luckily these sports cars aren't on par with a Porsche. The 2021 Subaru WRX runs an average of $682 annually for maintenance. In addition to the upkeep, Repair Pal has also noted several complaints about the 2021 model. In particular, check engine errors due to failed knock sensors and spark plug wires.

On the other hand, the 2016 Subaru WRX STI is a bit pricier per year for maintenance at $780. Despite the higher cost, the STI has no complaints reported to Repair Pal, which means the STI can stay on the road longer before needing some critical repairs!

3 Initial Purchase Price

Here's where the battle hits the wallet. The biggest question is about the price. Though a brand new STI starts almost $10,000 more than a base WRX, the several years of difference between the 2021 WRX and the 2016 WRX STI has brought a closer battle in terms of price.

Finding a 2016 STI can be tricky, but the average model sells for around $26,000. This price is quite the discount considering the average 2021 Subaru WRX sells for $29,000, and with options and features, that price extends well into the $30,000 range.

2 Trims And Options

2021 gives the Subaru WRX three trim choices. Base, Premium, and Limited trims are available for the WRX with leather seats and sunroof available on the Limited trim. Further, these trims and options can add significant increases to the price!

For 2016, the Subaru WRX STI only has two trim options, the Base and Limited trims. Though for 2016, spoiler type was an option, giving drivers their pick between the big wing or the subtle trunk lip spoiler. Again, the Limited trim offers upgraded interior seats and a sunroof.

1 Which Subaru to get

The 2021 Subaru WRX upgrades the interior over what 2016 had to offer in the STI. Despite the upgrade, though, the interior doesn't make up for the increase in power the STI has over the WRX. Additionally, the STI features advanced drive modes that alter torque, suspension feel, and steering response, options that still remain missing in the WRX.

Finally, the 2021 Subaru WRX price can't compete with the 2016 STI. The several thousands of dollars saved by buying several years used are more than adequate to fix any mechanical issues. Though, there might be more issues to worry about with the WRX than the STI, which makes it a no-brainer decision for which Subaru to buy!
