An Unusual Collaboration Between Porsche and Subaru

When people hear “Porsche,” they often picture a German luxury sports car.

But did you know that Porsche Design once collaborated with Japanese automaker Subaru on a high-performance sedan? Meet the Legacy B4 Blitzen. Sold exclusively in Japan from 2000 to 2003, this special model featured exterior and interior design by Porsche Design.

Porsche Design is a design company founded in 1972 by Professor Ferdinand Alexander Porsche, known for designing the 911.

The company has created everything from luxury watches and pens to kitchenware, earning worldwide acclaim for its sophisticated designs. For car enthusiasts, Porsche Design’s involvement in a Subaru sedan was a fascinating meeting of two very different automotive worlds.

What Made the Legacy B4 Blitzen Special?

The Legacy B4 Blitzen was a special-edition model based on the Subaru Legacy of its time. “Blitzen” is German for “lightning,” a fitting name for a car built to deliver high performance. Its tagline was “God is in the details.”

Porsche Design gave the exterior a major makeover. The front bumper featured two large air intakes, while the side skirts and rear bumper were designed specifically for the Blitzen. The standout feature was the double-bubble-style rear wing. Together, these aerodynamic details gave the car a distinctive presence, with a more upscale and aggressive look than the standard Legacy.

The interior was also extensively refreshed, with premium leather and other high-quality materials throughout. A MOMO steering wheel and shift knob, along with a boost gauge mounted on the steering column, brought together sporty character and an upscale feel.

A 280-PS Twin-Turbo Engine

At the heart of the Legacy B4 Blitzen was Subaru’s signature boxer engine. Its 2.0-liter, four-cylinder engine paired with sequential twin turbos produced 280 PS—the maximum permitted under Japan’s voluntary horsepower limit for domestic cars at the time. With 343 Nm of torque, it could sprint from 0 to 100 km/h in just over five seconds.

The sequential turbo system was designed to deliver smooth acceleration across the rev range. One turbo operated from low to mid engine speeds, with the second joining in from the midrange to higher revs.

Buyers could choose between a five-speed manual and a four-speed automatic. Manual versions also came with a dedicated limited-slip differential. A front strut-tower brace was added to improve body rigidity.

A six-cylinder version, the Blitzen 6, was later added to the lineup. Its naturally aspirated 3.0-liter engine produced 220 PS at 6,000 rpm and 29.5 kg·m of torque at 4,400 rpm.

What’s Next for This Elusive Performance Sedan?

Although production of the Legacy B4 Blitzen ended after a limited run of just three years, it has remained fondly remembered by enthusiasts. At the 2015 Tokyo Auto Salon, a Blitzen concept based on the sixth-generation Legacy drew attention—but it never made it into production.

Sadly, Subaru has also decided to retire the Legacy nameplate after 2024. The end of a model line that had been cherished for so many years is sure to leave many fans feeling nostalgic.

Perhaps the Legacy’s story might have taken a different turn if Subaru had once again called on Porsche Design to create a high-performance sedan for a new era. There are plenty of possibilities to imagine, including a new model that packages WRX performance in a more refined form.

The Legacy B4 Blitzen was a one-of-a-kind car born from the unlikely pairing of Porsche and Subaru. Its story reminds us how important it is for automakers to take bold creative risks.

Car enthusiasts everywhere will surely be hoping to see another refreshingly unexpected collaboration like this one.
