The 2021 WRX STI range consists of two models: the base STI, and the STI Limited. Both of them are powered by a turbocharged 2.5-liter flat-four engine with 310 hp and 290 lb-ft. A six-speed manual gearbox is the only transmission option, and Subaru's symmetrical all-wheel-drive is standard fitment. The base STI has 19-inch alloy wheels, daytime running lights, and LED headlights. On the inside, it has manually-adjustable Ultrasuede/leather sports seats, dual-zone climate control, STI gauges, and keyless entry with push-button start. The standard infotainment system has a seven-inch touchscreen with HD Radio, Apple CarPlay, and Android Auto. The STI Limited adds Recaro front seats with eight-way power adjustment for the driver, navigation, a nine-speaker Harman Kardon premium sound system, a power moonroof, blind-spot detection, lane-change assist, and rear cross-traffic alert.
The base WRX STI has an MSRP of $37,245 while the WRX STI Limited costs $41,945. The brand also charges a destination and delivery charge of $925 in the US.
On the base STI, there is one optional package which retails for $2,250. It only adds the Recaro performance front seats with eight-way power adjustment for the driver. There's only one optional package for the STI Limited and it's the low profile trunk spoiler. It's a no-cost option, and one you should tick if you like seeing out of the rear window. There are a few standalone options you can spec, including an Ultrasuede steering wheel ($499), an STI-branded shift knob ($185), and an auto-dimming mirror with a compass and Homelink ($359).
There's a $4,700 price difference between the base STI and the STI Limited in the USA. Considering that the Recaro seats alone nearly account for half of that price difference, the STI Limited does make more sense. In addition to the fancier seats, you also get a Harman Kardon premium sound system, navigation with voice activation, blind-spot detection with lane-change assist, and rear cross-traffic alert. Look at it that way, and the Limited makes more sense. If, however, you want the driving experience and nothing else, the base STI should do just fine.
