Subaru announces WRX STI Diamond Edition


It was just last week that Subaru teased us with the JDM TC380, a 380hp special, developed in partnership with Japanese rally driver Toshihiro Arai. Now, to make matters worse, the manufacturer's South African operation has announced its own limited-run car, the Diamond Edition.

Uprated to produce a claimed 348hp and 342lb ft thanks, in true modded Subaru fashion, to a remap and a new performance exhaust, the model is the most powerful the region has ever seen - though still not as potent as the UK's 395hp CS400 or, of course, that TC380.


Nonetheless, 0-62mph in 5.0 seconds - a 0.7 second improvement on the standard STI - sounds plenty quick to us. Handling ought to be improved too, thanks to a new engine brace and six-piston calipers all-round for the Brembo brakes. Spacers on the 19-inch Y-design wheels make for a 20mm wider track, and a more aggressive stance, while High Viz Yellow detailing completes the package aesthetically.

Inside, each Diamond Edition car receives a unique numbered plaque and model-specific dashboard inlays, as well as a seven-speaker Harman Kardon audio system and a seven-inch CarPlay/Android Auto-enabled infotainment system.


Just 30 examples of the Diamond Edition will be produced to mark the 30th anniversary of STI, with deliveries expected to begin in January of next year. Still, with South Africa and Japan both driving on the left, add those 30 to the 50 TC380s being made and the odds of a determined UK Scooby fan getting their hands on a new, limited-run car have just increased significantly...

    I think this shape is really handsome, I saw one fly off a round about last week and it sounded so dramatic and racey compared the the usual 4 pot hatches circa 300hp.

    You guys probably know I'm a huge Subaru fan. And this just leaves me very unimpressed.

    Subaru were great back in the 90's, and even some of the early noughties cars like the JDM versions of Spec C, Type RA, s202/3/4 were scalpels around a track.

    But these are just fat bds with a few trinkets sprinkled around the cabin, while the rest of the world has moved on.

    That is a real missed opportunity as far as I'm concerned. Put that pig on a diet, give it some muscles, and then let's have another look at it.

    If I remember correctly, my RB320, with 320bhp, did 0-60 in 4.8s. This is 0.2s slower and 28bhp more. Too many pies maybe.....?
    Maybe they've strengthened the engine? Let's hope so.

    I tend to agreed. Having had a number of scoobies over the year and an avid fan of the early rally hay days and drivers (one main ingredient in me love of all things petrol and driving). These seem just a bit soft and lacking. I am a fan of the design and would choose one over a bunch of other more expensive luxury cars.

    That said. When compared to the rest of the fair on sale today i still think its stands fairly outside the "norm" for brutish saloons. I guess they have to compete with the more modern VAG / German super saloon equivalents and that means more kit and therefore more weight. Which i think is a shame. Plus they don't do it that well, so just accept that and don't do it. Subaru's USP is how it drives, feels, sounds. How it holds the road - it should use that to sell cars not try and compete in ways where it can only fail.

    A celebration of everything STI should include lightweight body panels, stripped back interior, a modified forged engine with circa 380-420hp. You, the steering wheel and that boxer and drive train. And if they were really a celebration then they should wear the "impreza" badge. It seems a bit sad that it doesn't, perhaps above all else.

    For a country that proved so popular for subaru and imparticular imprezas its also a shame that subaru doesn't feel its right to provide the UK with a celebration model - massively frustrating. Please bring it back!!!

    Are those 0-60 times using South African fuel or something?

    5.7 seconds to 60 for the standard STI is slow, frankly
