Subaru claims adding a turbo would harm BRZ’s performance
Although most enthusiast faithful seem to have given Subaru’s newly released BRZ (and its bump in power over the outgoing model, their blessing) their blessing, there’s still an undercurrent of fans who seem perplexed as to why the model neglected a turbocharger.
As reported yesterday, the new BRZ sports a new (to it) 171kW/249Nm ‘FA24’ 2.4-litre naturally aspirated four cylinder. Peak power comes at 7000rpm, with redline following at 7500rpm. This means those behind the wheel will need to wring the sportster’s neck in order to extract peak performance — a negative to those wanting instant results but a huge positive for enthusiasts seeking a true driver’s car.
Now, Subaru has offered another reason for not tacking a turbo onto its 2.4-litre flat four — performance.
It’s an odd bit of reasoning that will have the eyebrows of a few enthusiasts dancing, but it’s true according to Subaru PR chief Dominick Infante. Speaking to Road&Track, Infante said that lifting the turbocharger from the Subaru Ascent (the American market seven-seat SUV that the BRZ borrows its engine from) would have harmed the car’s abilities.
According to Infante, the turbo would have added weight and required an increase to the BRZ’s centre of gravity to a level that would have made the rear-driven sports coupe worse to drive. The 2.4’s turbo is mounted to its bottom, which at first makes Infante’s claims sound like gobbledygook. But, the PR chief says that because of this the whole car would need to be constructed differently to have the engine sit higher to allow for the turbo.
Infante doesn’t explain whether Subaru investigated putting a turbo elsewhere on the new engine. Undoubtedly, the tuning community will find a way to tackle the challenge when the model eventually hits showrooms at the end of 2021.
The same report also notes that adding a turbo to the BRZ would have harmed its pricing. While pricing hasn’t been confirmed for the model just yet, it’s expected to occupy the same space as its long-time rival, the Mazda MX-5.
