Overview

The Subaru Impreza WRX and WRX STi are fun, fast and well built, with standard all-wheel drive and overall performance that's rare in their class. A redesign for 2008 hasn't significantly diluted the character and enthusiasm that have made the WRX so appealing over the years. The new models just raise the bar on comfort and refinement.

The 2008 WRX and WRX STi can legitimately be called all new, meaning virtually everything from the interior to the styling to the suspension and underlying structure have been overhauled. Both are somewhat larger than before, with a corresponding increase in interior and cargo space. The available engines and transmissions are essentially the same, though the extra-muscular STi gets a slight power increase.

The WRX and STi are higher-performance versions of Subaru's standard Impreza, though both are different enough that they might be considered separate cars. Both were developed within and made famous by Subaru's highly successful World Rally Championship racing program. While its roots rest in the smallest car line Subaru sells in the United States, the STi's price, performance and reputation make it a flagship of the company's lineup.

The WRXs have achieved cult status among driving enthusiasts and boy racers, but more than ever that image is too narrow and confining. These cars are also practical, with decent room in the back seat and good cargo capacity. Measured in the full spectrum of vehicles available today, they get good mileage (though less than many comparably sized, two-wheel-drive cars). Their all-wheel-drive system can legitimately be considered a safety and foul-weather advantage, even if, with the powerful, turbocharged engines in the WRX, it's marketed primarily as a performance enhancement.

And now, the WRXs are even more refined. They're smoother, more comfortable, and easy to live with during the typical commute. Their cabins are roomier, with an overall improvement in appointments and finish quality. There's also an upgrade in the equipment available, including better audio systems and an optional navigation system for the first time. In short, the 2008 WRX models should appeal to a broader range of buyers.

The standard WRX is powered by a 2.5-liter, 224-horsepower turbo four-cylinder, with cylinders arranged in Subaru's familiar flat, or horizontally opposed, configuration (like a Porsche engine). Both body styles are available with an optional automatic transmission that doesn't substantially reduce the fun-to-drive factor.

The WRX is available as a four-door sedan with a conventional trunk or a five-door hatchback that more than doubles maximum cargo capacity and adds another level of flexibility. At about $25,000, both sedan and hatchback come well equipped, with automatic climate control, an 80-watt stereo and more power than all but a couple cars in this size/price class. The bang-for-the-buck surpasses many more expensive sports sedans.

The WRX STi is essentially its own car, and available only as a hatchback. Nearly every major mechanical system is unique to this model: six-speed manual transmission, special suspension and brakes, unique interior appointments and a high-tech, manually adjustable all-wheel-drive system. Yet the STi's centerpiece is a higher-tech, higher-boost version of the 2.5-liter four, generating 305 horsepower. Its acceleration times match those delivered by exotic sports cars such as the Aston Martin V8 Vantage. STi stands for Subaru Technica International, the high-performance division that made the WRX famous through considerable success in the World Rally Championship. Beyond its more powerful engine, the STi adds a host of mechanical and performance upgrades, including bigger brakes, more sophisticated chassis electronics and a unique, manually adjustable center differential.

The new STi is at least as fast as ever, but it's also quieter, more understated, and easier to drive quickly. It reeks refinement when compared to the STi that first went on sale in the United States in 2004. It's grown from an in-your-face, sport-compact icon to something more like a true, brand-building performance flagship. It also starts $10,000 higher than the base WRX. We suspect that most buyers will be just as happy with the standard version.

Buyers seeking a smaller car with a lot of safety features should also like the WRX. Beyond all-wheel drive, all models come with a fairly comprehensive list of active safety systems, including Vehicle Dynamics Control anti-skid electronics and sophisticated anti-lock brakes (ABS) with electronic brake-force distribution (EBD). The WRX gets excellent ratings in National Highway and Traffic Safety Administration (NHTSA) crash tests, and all come with dual-stage front airbags, front passenger side-impact airbags and curtain-style head airbags for all outboard occupants.

Model Lineup

The Subaru WRX comes as a sedan ($24,350) and a five-door hatchback ($24,850). Both are powered by a 2.5-liter, 224-horsepower turbocharged engine in Subaru's unusual horizontally opposed design, and both come standard with a five-speed manual transmission. A four speed automatic ($1,000) is available with the Premium option package. All WRX models are equipped with Subaru's Symmetrical All-Wheel Drive.

The WRX comes reasonably well equipped, with a full complement of power features, cruise control, 80-watt audio with an auxiliary input jack, automatic climate control, interior air filter and 17-inch alloy wheels. The hatchback adds nearly 70 percent more cargo capacity, a rear-window wiper and a split/folding rear seat.

Options include the Premium package ($2,000) with heated front seats and an 11-speaker audio system with a 100-watt amplifier, among other things. The Navigation package ($4,000) includes the Premium package contents plus a GPS navigation system with seven-inch screen, satellite radio, digital sound processing, Bluetooth connectivity and an auxiliary video jack. Standalone options include body molding colors ($180), various deck-lid spoilers ($335), a battery warmer ($30), a subwoofer and power amp for the base audio system ($370), and XM or Sirius satellite radio hardware ($398).

The WRX STi ($34,995) is available only as a hatchback, and only with a six-speed manual transmission. The STi is equipped comparably to the standard WRX with Premium package, though the extra money mainly adds performance, starting with the 305-hp 2.5-liter engine.

STi options include forged, 18-inch BBS wheels ($2,000), in gold or silver, and a Navigation package ($3,800) that includes the navigation system, BBS wheels, and leather upholstery.

Safety features, in addition to all-wheel drive, include Vehicle Dynamics Control anti-skid electronics and four-channel, four-sensor anti-lock brakes (ABS) with electronic brake-force distribution (EBD). EBD keeps stopping power balanced between wheels regardless of the traction underneath. All models come with dual-stage front airbags with occupant sensors. Front passenger side-impact airbags and curtain-style head airbags for all outboard occupants are also standard. The WRX has achieved some of the best ratings in its class in National Highway and Traffic Safety Administration (NHTSA) crash tests, with five stars for front impacts, five stars for front passengers in side impacts, and four stars in rollover tests.
