Subaru releases specs on Impreza WRC 2008
Click above for a high-res gallery of the Subaru Impreza WRC 2008.
WRC teams are gearing up in Greece ahead of this week's Acropolis rally, and just before its world racing debut, Subaru has released the details on its all-new Impreza rally car. You can pore over the specs after the jump, but the highlights of the Impreza WRC2008 include a 1994cc turbocharged flat four, running an IHI turbo equipped with the WRC-mandated 34mm restrictor plate and Subaru's own anti-lag system to produce 300 hp at 5,500 rpm and... wait for it... 479 lb.-ft. of torque at 3,000 rpm.
Power is sent to a six-speed electro-hydraulic transmission, through an electronically controlled center diff and down to the wheels through mechanical differentials, fore and aft. Bos shocks are being used in conjunction with the front and rear MacPherson setup, while AP Racing, 310mm discs are clamped by six-piston calipers both in front and in the rear. BBS wheels are fitted at all four corners, with 15-inchers used for gravel stages and 18-inch rollers for tarmac attacks. The rally racer's weight is set at the WRC minimum of 2,712 pounds. As always, you can follow the progress of the Impreza and the rest of the teams at the WRC website.

+1 Schwarma so good!

Doesn't look bad at all, but man WRC has been really boring for the last few years.....it's almost painful to watch now. The FIA really needs to give the sport a real work over, for some reason these days the cars look almost the same as the street versions and almost as slow....I really don't understand why.

Slow as the street versions?! I'm not seeing you doing +160kph on the edge of a cliff or in tight forest roads in street cars...
Maybe WRC is boring because of Loabs total control over it but it is definitely not slow.
anyway , this car looks much better than the hideous road STi version with that ugly bonnet.
Neil 2:09PM (5/29/2008)
I'm not saying drivers aren't putting their lives on the line and that the sport isn't dangerous. But to me the cars seem much slower than previous years, and what happens when they're not running by the side of a cliff? Then 160kph doesn't really seem all that impressive, I mean thats like what 100mph ? (give or take)

Ding! Ding! +10000...000
That, and he's about as charismatic as a cow. The Solberg brothers and the two young Finns of Ford's are much more interesting to watch and listen to. Even Sordo (Loeb's "team mate") is more interesting.

The WRC was never as fast as today... thanks to modern technic tires etc.
What makes WRC currently boring that the race cars shares noting with the road going versions... only the shape and look
Stuka 3:08PM (5/29/2008)
nagmashot: Say what? Class B cars were loads faster than todays cars. Todays cars are limited to 300hp, but unlimited torque. Class B cars had no limit on power, period. Hense you had cars like the Delta S4 with its twin-charged engine, the Ford RS200 with its space frame chassis, etc. The reason Class B was banned was because the cars were too fast.
Cortez 3:16PM (5/29/2008)
Mate you should really go too a WRC,you have no idea what speeds they are doing when you watch it on TV.160kph isn't fast!! then try doing it in a gravel road,Mate you have no idea.
nagmashot 3:33PM (5/29/2008)
@Stuka
lot of power means nothing without controll.. Group B cars were beasts .. on paper and to drive fast...
Formula 1 turbo cars of the past were much mor powerfull as the one today... and a today F1 car would drive circules around the more powerfull old F1 cars...
sure the power is limited to 300hp.. but they take turn faster, are earlyer on the throttle have MUCH MUCH better brakes can brake much later, they have much better suspensions that allows much higher speed on rough trails... fast is not only hp claiming

The stock rear suspension geometry is multi-link or A-arm, which is usually considered superior to Mac struts (better dynamic camber, etc.). I wonder why they put Mac struts on the rear?
Reply
Krystian 2:15PM (5/29/2008)
I believe they use Mac Struts because they are superior on Off road surfaces (compared to Multi Link which is superior on smooth surfaces).
RoadrunnerSTi 1:56PM (5/29/2008)
Wow... that must be a super tight fit over those 6-piston calipers when they are running the 15" wheels on the gravel stages.
I'd still keep my pig-nose STi over this one.

remember they run a different brake spec on gravel.
rouse42 1:58PM (5/29/2008)
baby godzilla!
top gear should test this thing against the GT-R
how about the ZR1 GT-R and this thing at the Ring!

oh and then just for fun remove the restrictor and watch it kick ass.
Neil 2:14PM (5/29/2008)
I really don't get why the pinnacle of rallying would feel the need for restrictor plates....other than for a few races where maximum speed might pose an unacceptable amount of risk to spectators.
DJ_Swammi 2:18PM (5/29/2008)
Why restrictor plates?

Eric 3:38PM (5/29/2008)
so people don't die. which i believe the previous poster was getting out.
group b was nick named the killer bee's because there where so many deaths. it eventually got banned.
the restrictor plates are a way to slow the cars down as well as level the playing field. A lot of motor racing use this in various forms, including f1 with the maximum size intakes.
Karan Shah 3:12PM (5/29/2008)
Is it odd that I find that car sexy?
