What does WRX mean? What does STi stand for?

The Subaru WRX performs. The rally powerhouse added to its scores of first place finishes with the top spot at the Rally in the 100-Acre Wood.

David Higgins and Craig Drew dominated at this weekend's snowy Rally in the 100 Acre Wood. With ice covering 50% of the roads yesterday and steady snow all day with 6+" of accumulation, this was a true snow event. The 2015 Subaru WRX STI handled the treacherous conditions with ease and performed flawlessly all weekend.

"These were some of the toughest conditions I've ever driven on," explained Higgins at the podium. "There was a mix of everything. At a snow rally you at least know you are dealing with ice or snow, but here we also had gravel, frozen gravel, icy gravel and everything in between to go with the snow. Then when it began to snow late in the event the fresh snow hid the icy parts from view. Our new 2015 Subaru WRX STI was perfect again and Craig Drew did a fantastic job, this was a huge challenge."

So what does WRX mean?

Subaru World Rally eXperimental (some locations: World Rally Cross). The WRX was developed to showcase Subaru's technical prowess, including showing off the symmetrical all-wheel drive which gives an incredibly responsive feel. Subaru basically modified an Impreza, giving it a turbocharged engine with the boosted horsepower and torque. Within five years of being rolled out, the WRX had won three World Rally Championships.

Subaru won't rest on its laurels, though. Always looking to improve performance and handling, the WRX has been improved with a stiffer body, which improves the action of the suspension. Engineers have even gone so far into performance details as to adjust the direction and angle of suspension springs, to squeeze out every bit of improvement possible. And it's paying off. In the last ten years, Rally Team USA has won seven championships.


What does STi stand for?

Subaru Tecnica international. Basically, Subaru's skunkworks for motorsports. Subaru Tecnica international develops the Subaru racing vehicles, and the WRX's that bear the cherry blossom red STi badge are those with the highest high performance parts.

The WRX STi was introduced in 1994, and at the time was basically made just like the WRX that had some key parts replaced. At the end of 1994, the WRX STi had its own dedicated assembly.
