Subaru shows racing versions of STI and BRZ

While we gear up for next week's Detroit Auto Show, the 2015 Tokyo Auto Salon is currently on going, and Subaru has marked the occasion by trotting out a pair of new racers. First up, we have the car shown above, with the company's entry to the 2015 Nurburgring 24 Hour Race. Subaru is entering a WRX STI in the grueling endurance race, which runs from May 14 to May 17. The left-hand-drive racer has received a fair crop of upgrades for endurance duty, although Subaru didn't really bother to elaborate on them, unfortunately. Next to the N24 car, Subaru introduced a striking version of its rear-drive BRZ, destined for the Japanese Super GT series. The team campaigning the BRZ will be led by Subaru's Hideharu Tatsumi, who will also be one of the drivers for the Nurburgring effort. Again, Subaru hasn't offered any info on technical changes for the BRZ GT300. Scroll down for the brief press release, and then check out the galleries of both cars. 2015 SUBARU Motorsport Activities Tokyo, January 9, 2015 – Fuji Heavy Industries Ltd. (FHI) - the maker of Subaru automobiles and Subaru Tecnica International Inc.

Toyota GT86 engineer Tada recounts how sports car came to be

Because the Toyota GT86, Scion FR-S and Subaru BRZ coupes are now a reality, it's almost hard to imagine the struggle that had to happen within the large, conservative corporate structures at both automakers for the joint project to even get off of the ground.
Speaking to those struggles on Toyota UK's Toyota Blog, GT86 Chief Engineer Tetsuya Tada enlightens us with a recap of the sports car's earliest origins. For Tada, the first stages of the project must have seemed almost as dreamlike as the final product is to drive.
Said the Chief, "I had been working in the minivan department engineering new product, but a month after the meeting I was summoned. 'Forget about minivans,' they said, 'you are now working on the sports-car project.'"

Cosworth announces Power Packages for Subaru BRZ, Scion FR-S with up to 380 hp [w/video]

Cosworth stands on the list of the most famous engine tuners in the world with its DFV engine engine dominating Formula One for a time in the '70s. So when it teases plans to take on the FA20 engine from Subaru and Toyota found in the BRZ, Scion FR-S and Toyota GT86 abroad, our interest is indeed piqued. Cosworth is promising to take the 2.0-liter, four-cylinder boxer engine from its current 200 horsepower all the way to 325 hp and even 380 hp in a future track version through a series of staged Power Packages. At the moment, only the first stage is available that takes the mill to a potent 230 hp.
Cosworth says that its new strategy is to offer its upgrades in kits rather than individually so that it can be sure that everything works and fits when owners receive it. The Stage 1 Power Package emphasizes helping the FA20 breathe better and includes a nearly complete replacement for the stock exhaust system. There is a sports exhaust with four-inch, diagonally cut, polished tips and Y-shaped muffler, an overpipe front pipe with a spherical resonator and a new manifold header that is 22 percent lighter the standard unit. In addition to that, the kit comes with a software reflash, low temperature thermostat, Cosworth badge and plaque.
The stage one kit is available now, and stages two and three go on sale later this summer, according to its website. Autoblog contacted Cosworth for pricing information for the kits. We will update this story, if we hear back. The company also released a video showing off the exhaust upgrades. Scroll down to watch it and read the full release, below.
