The latest is the Crouching Tiger. You can't miss it, because it's very orange. It's also very rare, with just 10 examples going on sale. Subaru's last limited-edition WRX, the Ace of Spades, was produced in a run of 10 examples as well.
In fact, the Crouching Tiger has a lot in common with the Ace of Spades under that orange finish. The 2.5-litre boxer-turbo engine has been tweaked to 211kW (more than the standard WRX's 195kW, a bit less than the STI's 221kW), there's an STI strut brace under the bonnet and STI front springs. Like the Ace of Spades, the Crouching Tiger has privacy glass, a 'WRX' garnish on the front fender and glossy black alloys.
However, the orange crusher ups the ante on rear spoiler size. And orangeness of course. The Tiger features orange stitching on the leather seats and 'WRX' logos in the seatbacks in the same lurid colour.
If you're thinking the Tiger is simply a brighter version of the Ace of Spades then you're probably on the right track.
I can't see anything wrong with that either, as there are only 10 to go around and it's a brilliant package. This particular setup makes for what is arguably the best WRX ever and once you drive it you can't get enough.
Sure, it looks a bit old-fashioned now and the interior fit/finish is diabolical compared with the new Impreza, but the WRX still offers a real connection between car and driver.
It would make sense to say that the car's drawback is you have to go crazy to really enjoy it, but that's a WRX myth. Sure, this can be a mad machine, but it's also one of those rare cars crammed with feedback and dynamic character even at urban speeds. Like any action star with enduring appeal, the WRX knows how to pace itself.
THE BOTTOM LINE
The Crouching Tiger costs $54,990. That $5000 over the standard WRX is well spent, even if you don't like orange. Although it definitely helps to like orange as well.
