All-wheel drive, turbocharged and adorned with a big flat spoiler, the Subaru WRX STI is sure to be popular with driving enthusiasts. Seen alongside the less powerful WRX, the STI makes its Canadian debut this weekend. While the WRX uses a 2.0-liter turbocharged engine to make 268 hp, the STI will use a 2.5-liter boxer engine to make 305 ponies. Either way you take it, these cars are built for snowy Canadian winters.
