Remember earlier this year when it was revealed that the Toyota Supra actually produced more power than Toyota advertised? Well, it looks like it isn’t the only Toyota that’s more powerful than we thought.

A recent dyno test conducted on the GR Yaris revealed that Toyota’s firecracker of a hot hatch comes with a 1.6-liter turbocharged three-cylinder engine that produced more than Toyota’s claimed output of 268 horsepower and 272 pound-feet of torque. A video of the GR Yaris getting tested on a dyno shows just how much more power the turbocharged three-cylinder can crank out, and without dumping any spoilers, it’s a lot of extra power that we didn’t think the GR Yaris had at its disposal.

How much more power are we talking about here?

Before answering that, let’s set the table first with Toyota’s claimed output for the GR Yaris. According to the automaker, the GR Yaris’ 1.6-liter turbocharged three-cylinder engine produces 268 horsepower 272 pound-feet of torque. It's an impressive amount of power for a compact hatchback, but in the interest of full disclosure, the GR Yaris that’s strapped on a dyno in the video is a Euro-spec model. That model produces 257 horsepower and 265 pound-feet of torque, which makes the results of the dyno test look even more impressive.

What does this mean?

It means that there’s more power available to the driver than Toyota claims. That’s always a good thing to know, especially if you’re buying a GR Yaris specifically to go to town with it.

Granted, the dyno test does come with a few qualifiers, including the caveat that the output clocked during the dyno test was not recorded at the wheels. Instead, the figures are “estimates” on the amount of power the engine produces at the crankshaft based on the horsepower and torque figures recorded at the wheels.

The other important caveat is just as important. This is the first dyno test we’ve seen of the new GR Yaris, and while the numbers it generates are impressive, more data from other dyno tests have to come out in order to validate the numbers that this dyno test managed to show. If future dyno runs involving the GR Yaris reveal higher outputs than Toyota’s claims, then that’s the time to start getting excited. On the other hand, if this test turns out to be an aberration, then, well, that’s a bummer.

Mind you, this isn’t the first time that a Toyota performance car produced more power on the dyno than the automaker’s claims. The Supra was tested on a dyno numerous times earlier this year, and it was revealed that it had more power on tap than Toyota’s claims. Car and Driver, for example, independently tested the Supra on a dyno and that rest revealed an output of 339 horsepower and 427 pound-feet of torque at the wheels.

Mind you, that’s at the wheels, which typically receive around 90 percent of the power that comes out at the crank because of the 10 to 15 percent driveline and hydraulic power loss that’s normal on automotive drivetrains. So if C&D’s test for the Supra revealed 339 ponies and 427 pound-feet of torque, an output of around 380 horsepower and 480 pound-feet of torque at the crank was possible.

Here’s the bottom line: we need to see more dyno tests involving the GR Yaris to determine whether the 1.6-liter turbocharged three-cylinder engine that powers the hot hatch produces more juice than Toyota says it does.

The signs do point to that, so if you’re looking to buy a Toyota GR Yaris anytime soon, that should ring as music to your ears.
