The Toyota GT 86, Scion FR-S, and Subaru BRZ are inching closer to getting a release date, and the lucky dogs over at Edmunds managed to get their hands on an FR-S a little early. Being the true car buffs that they are, what’s the first thing they did with it? They threw it on the dyno, of course!
You may be alarmed wondering why they are dyno testing a car that we all know produces 200 horsepower. Well, that’s not always the case. See, 99.9 percent of the time, automakers release horsepower numbers based off of the engine’s power, not the entire car. On average, you can expect to lose 10 to 20 percent of the horsepower through the driveline – transmission, driveshaft, and differential.
So what was Edmunds’ final determination of its horsepower? It was nothing short of impressively consistent. It repeatedly produced 173 horsepower at roughly 7,000 rpm and 143 pound-feet of torque at about 2,800 rpm. Not only were the peaks identical, but the horsepower and torque curves were nearly identical on every run.
To have that kind of consistency in a car is a testament to just how much engineering went into it. This also proves that the 2.0-liter flat-four that Subaru and Toyota collaborated on is truly a work of art to crank out 173 wheel horsepower. There are not too many sub-$30K four-bangers hitting that kind of horsepower consistently without the use of some forced air.
There is one very odd thing in this engine that again shows how much engineering went into it. At about 4,000 rpm you will see a 14-percent drop in torque, which the Subaru and Toyota engineers intentionally did to allow greater torque on the lower rpm range. Our collective hats go off to the team of engineers that developed this car. Now, can we just get a hold of a turbocharged model, please?
