Less Attitude, More Space
So you want the big news with the 2008 Subaru Impreza WRX? It makes the same power but is lighter, roomier and still rips to 60 mph in just 5.9 seconds.
This is a rare combination. These days, every new model weighs more than the one before, and manufacturers keep adding power to compensate. Subaru has done exactly the opposite. Through the same clever engineering that brought the WRX to the U.S. in the first place, the Japanese carmaker has minimized the weight of this more spacious, all-wheel-drive WRX to retain its head-snapping acceleration.
But it's not all roses. The new WRX is marginally slower in the quarter-mile than the car it replaces — 14.5 seconds at 94.4 mph vs. 14.3 seconds at 95.5 mph. The chassis setup is also noticeably softer and there's no shortage of body roll.
On paper, it sounds as if the WRX really hasn't changed, but the WRX we loved for its finger-in-the-air attitude is gone, replaced by a WRX with its finger on the pulse of the mainstream market.
Stretch It Out
Probably the most notable change to the WRX is a 3.7-inch-longer wheelbase. Just two body styles are available — a sedan and a five-door hatchback. Subaru expects the sedan to make up 80 percent of WRX sales. The overall length of the five-door hatch has been reduced by 2.0 inches (to 172.8 inches), while the length of the sedan has increased 4.5 inches (to 180.3 inches). This means the five-door has shorter overhangs — a key trait for responsive handling. We're told that both the world- and U.S.-spec rally cars as well as the WRX STI version due early next year will all use the five-door body.
There's a new double-wishbone rear suspension to replace the struts used in the rear of the old car. In addition to adding camber control during cornering, the new suspension packages more efficiently and creates more passenger and cargo space in both body styles.
The 2.5-liter flat-4 power plant has only minor revisions for 2008. Some of the overall weight savings have come from a lightweight intercooler (which also flows more efficiently), and a new, lighter plastic intake manifold. The exhaust system is also lighter. Subaru's Active Valve Control System and swirl valves in the intake manifold remain.
Power delivery is improved, as peak power of 224 horsepower comes 400 rpm earlier at 5,200 rpm, while peak torque of 226 pound-feet arrives 800 rpm earlier at 2,800 rpm. Peak boost is 11.9 psi. The five-speed transmission has less aggressive ratios in 1st through 3rd gears, but the final drive is shorter: 3.90:1 instead of the former 3.70:1.
The majority of the weight savings comes from a redesigned body structure, which is 45 pounds lighter yet retains the same rigidity as the previous car. Subaru engineers tell us the suspension pickup points have been beefed up to improve ride control. Our five-door test car weighs 3,167 pounds, only about 4 pounds heavier than the last Mazdaspeed 3 we had on our scales. And the Mazdaspeed 3 doesn't offer all-wheel drive.

This is one ugly car inside and especially out, IMO. Edmunds didn't even take as many pictures of it as they normally do for a roadtest!
