2004 Subaru Impreza WR1

SUBARU UNVEILS SPECIAL EDITION STi TO CELEBRATE RALLY WIN

Subaru has unveiled a special edition Impreza WRX STi to celebrate Petter Solberg winning the Driver's Title in the 2003 World Rally Championship.

On sale in the spring and limited to 500 units, the ‘WR1' – as it will be called – will feature a power upgrade to around 320 PS plus a host of technical and visual upgrades.

For example, the Impreza ‘WR1' will feature a driver's control centre-differential (DCCD) via a switch mounted next to the handbrake.

It means the torque distribution between front and rear wheels can be manually selected. This allows the choice, for example, between a sharper cornering turn-in or more stable straight-line running. The system defaults to ‘automatic' mode whenever the ignition is restarted.

Also new for the ‘WR1' are special, Prodrive-developed uprated springs and bump-stops with a 25 mm lower ride-height.

Other handling-enhancing features include 18 ins diameter P-FF7 (Prodrive Flow Forming seven-spoke) alloy wheels with Pirelli PZero tyres.

Externally, the new ‘WR1' will be instantly recognisable thanks to its new Ice Blue Metallic paint plus driving lamps and a stainless steel mesh grille.

Interior changes include anthracite instead of blue suede-effect seats, a special gear knob, imaged carpet mats and a numbered tax disc holder.

Shared features with all Impreza WRX STi's range from a six-speed gearbox to Brembo brakes and front and rear ‘Suretrac' differentials.

The new Subaru Impreza STi ‘WR1' will enter dealer showrooms in April costing £29,995 on-the-road.

Subaru's fastest and most powerful Impreza ever – the WRX STi ‘WR1' – is about to enter dealer showrooms, with more than half of the 500 limited run already spoken for.

The special edition Impreza WRX STi celebrates Petter Solberg winning the Driver's Title in the 2003 World Rally Championship. It features a power upgrade to 320 PS plus a host of technical and visual upgrades and costs £29,995 on-the-road.

First unveiled in January at the ‘Autosport' show, the Prodrive-developed ‘WR1' has just received official Subaru (UK) engineering approval after recording the best performance figures ever for a road-going UK-spec Impreza.

Only 4.25 Seconds To Reach 60 mph

For example, 60 mph is reached in an astonishing 4.25 seconds with the 0-100 mph time at an equally impressive 10.67 seconds. Prodrive technicians also logged a quarter mile time of 12.8 seconds while the top speed is limited to 155 mph.

By comparison, the ‘standard' 265 PS Impreza STi is quoted with a 0-60 mph time of 5.1 seconds and a top speed of 151.5 mph.

Peak power for the ‘WR1' is 320 PS at a relatively low 5,800 rpm, with maximum torque or pulling power of 309.8 lb.ft at 4,000 rpm.

The ‘standard' STi produces 265 PS at 6,000 rpm and 253 lb.ft torque at 4,000 rpm while the optional Prodrive-developed Performance Pack liberates 305 PS and 299 lb.ft torque at the same revs and reaches 60 mph in 4.6 seconds and 100 mph in 12.2 seconds.

Other test track statistics see the ‘WR1' shaving 0.7 seconds off the STi's 30-50 mph time in 4th gear – down to 4.0 seconds – and 0.8 seconds off the 50-70 mph time in 5th – now 4.6 seconds.

Finally, illustrating its supercar-like performance, the new ‘WR1' boasts an 80-100 mph time of a staggering 3.6 seconds in 4th gear and 6.5 seconds in 6th (4.6 and 7.8 seconds for the 265 PS STi).

The ‘WR1's extra power and torque are achieved thanks to a revised engine control unit (ECU), high-flow catalyst and sports silencer.

Driver-Selected Torque Split Tailors Handling Balance

Also guaranteed to excite enthusiasts is a driver's control centre-differential (DCCD) via a switch mounted next to the handbrake.

It means the torque distribution between front and rear wheels can be manually selected. This allows the choice, for example, between a sharper cornering turn-in or more stable straight-line running. The system defaults to ‘automatic' mode whenever the ignition is restarted.

Also new for the ‘WR1' are special, Prodrive-developed uprated springs and bump-stops with a 25 mm lower ride-height.

Special Wheels, Body Colour And Interior

Other handling-enhancing features include 18 ins diameter P-FF7 (Prodrive Flow Forming seven-spoke) alloy wheels with 225/45 Pirelli PZero tyres.

Externally, the new ‘WR1' is instantly recognisable thanks to its new Ice Blue Metallic paint plus driving lamps and a stainless steel mesh grille.

Interior changes include anthracite instead of blue suede-effect seats, a special gear knob, imaged carpet mats and a tax disc holder engraved with the special edition number.

Features shared with all Impreza WRX STi's range from a six-speed gearbox to Brembo brakes and front and rear ‘Suretrac' differentials.

Introduced by Subaru in November of 1992, the Impreza is a compact car that was offered in either front wheel or all wheel drive and featured sporty curves. The Impreza came in both four-door sedan/saloon versions or five-door station wagon/estate. More compact than the Legacy, the Impreza had a more enhanced high-performance driving and feeling of quality than its predecessor.

The Impreza became Subaru's entry into the small-car maket segment in U.S., European, Japanese and numorous other world markets. ‘Subura' a Japanese word meaning ‘unite' has a reputation for reliability and customer satisfaction that is represented in their more than 10 million vehicles sold worldwide.

Equipped with a flat engine (or an internal combustion engine, also called a boxermotor) the Impreza came with distinguishable Subaru characteristics. With an engine choice of 1.5: or 1.8L naturally-aspirated engines that were neither turbocharged nor supercharged.

Available in a 4-wheel drive turbo charged version that delivered 211Bhp and had the distinction of the turbo charger mounted on the right side of the engine. The intercooler is located above the engine, therefore the reason for the big central air vent on the bonnet of the Impreza. On the racing version of the Impreza, the intercooler is located in the front bumper.

The Impreza came with an engine that was mounted longitudinally, making the gearbox and transmission much easier to fit and service.

For drivers searching for a car that provides thrills without major frills, the Japanese manufacturers have gained the status of being the only ones still able to produce a car for such a low price. Subaru Impreza turbo is gaining impressive commercial success due to price to performance ratio, its racing successes and reliable features.

The Impreza turbo's commercial success has led to production of more impressive versions that aren't available outside of Japan. The Impreza GT turbo evolved into becoming a multiple World Rally Champion with three world championship titles.

Common in Japan and Europe, special editions of the Impreza were available, usually coinciding with significant victories at World Rally Championships.

For the 1997 model year, the Impreza received an updated exterior facelift that was followed by a complete interior redesign in 1998.

A first-generation Impreza, turbocharged was never received in the North American market.

Subaru introduced its Impreza Compact Car in 1993 and has since become a pinnacle of performance. The name 'Impreza' was derived from an Italian word 'impresa', meaning a feat or achievement. In Polish, the name 'Impreza' means to 'party', an 'event' or 'show'. In either language, the name is suitable.

When the Impreza was first introduced in November of 1993, it was available in either front wheel drive or all wheel drive configuration. Two bodystyles were offered, a four-door sedan or five-door station wagon. The two-door coupe followed a few years later, in 1995. Trim levels included the LX, GL, and Sport. Adding to the vehicles versatility, the Impreza was offered with a variety of engines, including a 1.6, 1.8, and 2.0-liter engine. To boost performance further, a turbocharger and intercooler was available on the 2-liter engine. Horsepower for the forced-induction engine was an impressive 208. In the Japanese market, the output was even higher.

Subaru Tecnica International (STi) was formed in 1988; their purpose was to specialize in the preparation of vehicles for rallies. In 1994, they were given the opportunity to create a version of the Impreza to bear the 'STi' nameplate. When introduced, it was only available in the Japanese Domestic Market (JDM) and European Domestic Market (EDM). These versions featured performance-tuned engines, transmission, and suspensions. Horsepower was raised above the normal WRX models, and could carry the vehicles from zero-to-sixty in just 4.9 seconds. Top speed was electronically limited at 122 mph. The European market had a slightly de-tuned version of the engine, though performance was still impressive. Additional steps were taken to prepare the vehicles for rally competition. The soundproofing material was reduced, the air conditioning removed, and void of many non-essential amenities. The overall weight of the vehicle was reduced significantly.

The Impreza received cosmetic changes in 1997 and the interior was redesigned in the following year. The design-inspiration for the interior was borrowed from the Forester.

Special edition Impreza's have been introduced throughout its production lifespan. These limited edition models are often tuned for greater performance or given unique cosmetic changes. The purpose is often to commemorate a racing success or to honor a racing legend. Editions include the Series McRae, 555, Catalunya, Terzo, RB5, P1, and 22B. A limited edition version of the Impreza Wagon was even offered for a short time, dubbed the CasaBlanca.

The European market received a performance upgraded version of the Impreza in 1999 which featured an improved turbocharger and 4-pot calibers with larger disc brakes. The suspension was improved and the seating became more racer-oriented with bucket seats similar to the STi version.

While the rest of the world was offered the turbocharger version of the Impreza, the North American market was left to sit on the side-lines. The turbocharger would not come across 'the pond' during the first generation of the Impreza. The Impreza was offered with the 1.8-liter engine with either front- or all-wheel drive. A 2.2-liter version of the engine became available in 1995. The FWD was later droped and all Subaru's became all-wheel drive as standard.

Subaru was unsure of the performance market in North America, and thus, offered only basic engines. In 1998, the year the 1.8-liter engine was no longer available, Subaru decided to explore the possibilities of performance in the US. They offered a performance model dubbed the Impreza 2.5RS. The 2.5-liter DOHC naturally-aspirated engine produced 165 horsepower and had performance upgrades throughout the vehicle, including larger brakes and 16-inch five-spoke gold-colored wheels. Hood vents, rear spoiler, and a hood scoop helped segregate the styling from this 'special' model and its non-tuned sibling.

In 2001, Subaru introduced a larger, more refined and improved, Impreza. For some, the changes were a step in the wrong direction, as the car grew in size and weight. It was tamer beast for the typical day-to-day driving conditions and the extra size meant it was more versatile. Also, the coupe model was no longer offered.

The WRX version, for the United States, with its 2.0-liter turbocharged engine that cranked out nearly 230 horsepower became available the following year, in 2002. The US had to wait a long time to get the STi version, which did not enter into production for the States until 2004. To comply with safety and emission control laws in the United States, it was not the same thoroughbred racer as in other parts of the world. Still, it was a very impressive machine. In other markets, the STi was equipped with a twin-scroll turbocharger 2.0-liter engine. In the US, the STi was powered by a 2.5-liter EJ25 engine mated with a turbocharger.

In 2003, the Impreza was given a facelift, mainly due to the negative reaction by some media outlets. One of the more noticeable changes were to the headlamps, which became more square. Another redesign occurred in 2006 on all Impreza's, featuring changes to its headlights, taillights, and bumpers - among other changes.

The Third generation of the Impreza was introduced to the world at the 2007 New York Auto Show, ready for sale in 2008. It will be available as a four-door sedan and five-door hatchback.
