Sounds good, but will it get more power? That's been the No. 1 followup question since long before joint Toyota/Subaru effort that became the U.S. bound 2013 Scion FR-S (and its Subaru BRZ twin) rear drive sports coupe ever saw the light of day.

Reading the tea leaves after our recent drives of the FR-S and BRZ, it's all but certain that the Subaru-derived 200-horsepower 2.0-liter four-cylinder 4U-GSE boxer will eventually be boosted to deliver more horses, but when?

If the FR-S prototype that our very own Web production manager Kirill Ougarov recently spotted at Mazda Raceway Laguna Seca is any indication, it looks like it won't be long. Ougarov, who shot the photos and video, indicated that the white car was 'definitely' turbocharged -- turn up the sound as it drifts briefly around the corner and you'll likely agree.

Speaking of drifting, given that both the white-winged car and the car behind it were FR-S models, it stands to reason that this could be the Scion drift team getting in some testing before the 2012 season. Scion is heavy into drifting and has campaigned a tC modified to rear drive specifically for the team.

It's an absolute no brainer for the FR-S to take over as the Scion drift team star, but it stands to reason that in order to really get its drift on, the FR-S would need more power.

Whatever the reason for its presence at Mazda Raceway, the FR-S turbo sighting is good news for drift fans and all those who already can't wait for a higher spec version of the FR-S. Given that the base FR-S and BRZ won't be on sale in base form until mid-year, we wouldn't expect any turbocharged production model until close to the end of 2012.
