The car achieved 887 horsepower on a hub dyno, and the tuning company now says it’s ready for racing.

- LamSpeed Racing in Australia claims to have built the world’s first 1,000 horsepower (745 kW) GR Yaris engine.
- This car delivered 887 horsepower (661 kW) and 573 lb-ft (776 Nm) of torque to the hubs.
- Now, the tuner is preparing for its next challenge: harnessing all that power on the road.
The Toyota GR Yaris and GR Corolla stand out for several reasons, particularly for the engine platform they share. This platform features a compact 1.6-liter three-cylinder turbocharged unit that produces 257 hp (192 kW) in its standard form. Now, LamSpeed Racing, a company with an insatiable appetite for power, claims to have built one with 1,000 horsepower at the crankshaft.
To clarify, the GR Yaris in question produced 887 horsepower (661 kW) and 573 lb-ft (776 Nm) of torque at the hubs. This measurement was taken on a hub dyno, so referring to wheels would be technically inaccurate. You might wonder where the 1,000 horsepower figure originates.
LamSpeed accounts for a conservative estimate of at least 11.3 percent drivetrain loss between the crankshaft and the hubs.
In reality, the only way to verify that figure is by removing the engine from the car and testing it on an engine stand. Nevertheless, the performance is incredibly impressive, regardless of the exact output at the crank.
According to the dynamometer readout, the G16E-GTS engine achieved that power and torque at 8,730 and 7,701 rpm, respectively. In other words, once it started building power, it continued all the way to the redline. However, the power curve doesn’t really ramp up until around 4,200 rpm. If that doesn’t suit a small rally rocket, nothing will.

Even more impressive is that the engine is handling about 50 psi of boost from around 7,000 rpm and up. Now, LamSpeed Racing is set to take it to the track to see if they can effectively put that power to the ground.
The team has already set records at the drag strip, and with this level of power, they’re poised to do it again.
